TY - THES A1 - Forster, André T1 - Targeting Temporally Stable Vulnerability Factors in the Prediction of Long-Term Courses of Depression: Diagnostic Considerations and Therapeutic Protocols Based on Transcranial Ultrasonic Neuromodulation of Endophenotypes T1 - Untersuchung Zeitlich Stabiler Vulnerabilitätsfaktoren für die Vorhersage Langfristiger Depressionsverläufe: Diagnostische Erwägungen und Therapeutische Protokolle auf der Grundlage Transkranieller Ultraschall-Neuromodulation von Endophänotypen N2 - Depressive disorders represent one of the main sources for the loss of healthy years of life. One of the reasons for this circumstance is the recurrent course of these disorders, which can be interrupted by current therapeutic approaches, especially in the shortterm, but seem to be maintained at least in part in the long-term. Subsequently, on one hand, this thesis deals with methodological measurement issues in the longitudinal prediction of depressive courses. On the other hand, it addresses two currently discussed neuroscience-based treatment approaches, which are investigated experimentally in a basic-psychological manner and reviewed in the light of their potential to translate results to the application in patient care. These two approaches each address potential mechanisms that may negatively impact long-term disease trajectories: First, stable endophenotypes for vulnerability factors that could regain control over the organism and reactivate maladaptive experiences, or behaviors with increasing temporal distance from therapeutic methods are focused on. In the studies presented, these were influenced by a recently rediscovered method of neuromodulation (transcranial low-intensity focused ultrasound) which is discussed in light of its unique capability to address even deepest, subcortical regions at a high spatial resolution. Lastly, as a second approach, an experimental design for the use of reconsolidation interference is presented, which could provide a first insight into the applicability of corresponding protocols in the field of depressive disorders and thus contribute to the modification, instead of inhibition, of already mentioned endophenotypes. In sum, methodological considerations for monitoring and predicting long-term courses of depression are deducted before two approaches are discussed that could potentially exert positive influences on the recurrent nature of depressive symptoms on their own, in combination with each other, or as augmentation for existing therapeutic procedures. N2 - Depressive Erkrankungen stellen eine der Hauptquellen für das Einbußen gesunder Lebensjahre dar. Einer der Gründe für diesen Umstand liegt im rezidivierenden Verlauf dieser Erkrankungen, der auch durch bisherige Therapieansätze vor allem kurzfristig unterbrochen werden kann, jedoch langfristig zumindest in Teilen erhalten zu bleiben scheint. Daran anschließend befasst sich die hier vorgelegte Thesis zum einen mit der Messproblematik longitudinaler Vorhersagen depressiver Verläufe und zum anderen mit zwei aktuell diskutierten neurowissenschaftlich begründeten Behandlungsansätzen, die experimentellgrundlagenpsychologisch aufgearbeitet und im Lichte eines translationalen Ansatz hin zur Anwendung in realen Patientensituationen erörtert werden. Die beiden genannten Ansätze adressieren dabei jeweils Mechanismen, die sich negativ auf langfristige Krankheitsverläufe auswirken können: Zunächst werden hier stabile Endophänotypen für Vulnerabilitätsfaktoren, die mit zunehmendem zeitlichem Abstand zu Therapiemethoden erneut Kontrolle über den Organismus gewinnen und maladaptives Erleben und Verhalten reaktivieren könnten, in den Fokus gestellt. Diese wurden in den hier vorgestellten Studien mit einer vor wenigen Jahren wiederentdeckten Methode der Neuromodulation (transkranieller, niedrigintensiver, fokussierter Ultraschall) beeinflusst und vor dem Hintergrund der einzigartigen Möglichkeit dieser Technik, auch tiefste, subkortikale Regionen bei hoher räumlicher Auflösungsfähigkeit adressieren zu können, diskutiert. Zuletzt wird ergänzend, als zweiter Ansatz, ein experimentelles Design zur Nutzung der Rekonsolidierungsbeeinflussung vorgestellt, das erste Informationen über die Anwendbarkeit entsprechender Protokolle im Bereich der depressiven Erkrankungen liefern und somit zur Veränderung, Anstelle von Inhibition bereits genannter Endophänotypen beitragen könnte. Zusammengenommen ergeben sich hieraus zunächst allgemeine methodische Überlegungen für das Überwachen und Vorhersagen langfristiger Verläufe der Depressionen, aber auch zwei Ansätze, die für sich genommen, in Kombination miteinander oder auch als Augmentation für bestehende Therapieverfahren, potentiell positive Einflüsse auf die rezidivierende Natur dieser Diagnosegruppe haben könnten.

Therefore, we developed a self-guided IBI for family caregivers of patients with cancer (OAse), which, in addition to patients' spouses, also addresses other family members (e.g., adult children, parents). This study aimed to determine the feasibility of OAse (recruitment, dropout, adherence, participant satisfaction). Secondary outcomes were caregivers’ self-efficacy, emotional state, and supportive care needs. N = 41 family caregivers participated in the study (female: 65%), mostly spouses (71%), followed by children (20%), parents (7%), and friends (2%). Recruitment (47%), retention (68%), and adherence rates (76% completed at least 4 of 6 lessons) support the feasibility of OAse. Overall, the results showed a high degree of overall participant satisfaction (96%). There were no significant pre-post differences in secondary outcome criteria, but a trend toward improvement in managing difficult interactions/emotions (p = .06) and depression/anxiety (p = .06). Although the efficacy of the intervention remains to be investigated, our results suggest that OAse can be well implemented in caregivers’ daily lives and has the potential to improve family caregivers’ coping strategies.

Using a longitudinal research design with two measurement points, we investigated the ramifications of various psychological and organizational resources on employees' careers during the COVID-19 pandemic. Specifically, in a sample of German employees (N = 305), we investigated the role of psychological capital (PsyCap) for four career-related outcomes: career satisfaction, career engagement, coping with changes in career due to COVID-19, and career-related COVID-19 worries. We also employed leader–member exchange (LMX) as a moderator and career adaptability as a mediating variable in these relationships. Results from path analyses revealed a positive association between PsyCap and career satisfaction and career coping. Furthermore, PsyCap was indirectly related to career engagement through career adaptability. However, moderation analysis showed no moderating role of LMX on the link between PsyCap and career adaptability. Our study contributes to the systematic research concerning the role of psychological and organizational resources for employees' careers and well-being, especially for crisis contexts.

A1 - Richter, Aylin A1 - Hilger, Kirsten T1 - Multimodal brain signal complexity predicts human intelligence JF - eNeuro N2 - Spontaneous brain activity builds the foundation for human cognitive processing during external demands. Neuroimaging studies based on functional magnetic resonance imaging (fMRI) identified specific characteristics of spontaneous (intrinsic) brain dynamics to be associated with individual differences in general cognitive ability, i.e., intelligence. However, fMRI research is inherently limited by low temporal resolution, thus, preventing conclusions about neural fluctuations within the range of milliseconds. Here, we used resting-state electroencephalographical (EEG) recordings from 144 healthy adults to test whether individual differences in intelligence (Raven’s Advanced Progressive Matrices scores) can be predicted from the complexity of temporally highly resolved intrinsic brain signals. We compared different operationalizations of brain signal complexity (multiscale entropy, Shannon entropy, Fuzzy entropy, and specific characteristics of microstates) regarding their relation to intelligence. The results indicate that associations between brain signal complexity measures and intelligence are of small effect sizes (r ∼ 0.20) and vary across different spatial and temporal scales. Specifically, higher intelligence scores were associated with lower complexity in local aspects of neural processing, and less activity in task-negative brain regions belonging to the default-mode network. Finally, we combined multiple measures of brain signal complexity to show that individual intelligence scores can be significantly predicted with a multimodal model within the sample (10-fold cross-validation) as well as in an independent sample (external replication, N = 57). In sum, our results highlight the temporal and spatial dependency of associations between intelligence and intrinsic brain dynamics, proposing multimodal approaches as promising means for future neuroscientific research on complex human traits.

In addition to the physical threat posed by the viral disease (COVID-19), the pandemic also has implications for psychological well-being. Using a small sample (N = 51), we examined how Big Five personality traits relate to coping with contact restrictions during three consecutive weeks in the first wave of the COVID-19 pandemic in Germany. We showed that extraversion was associated with suffering from severe contact restrictions and with benefiting from their relaxation. Individuals with high neuroticism did not show a change in their relatively poor coping with the restrictions over time, whereas conscientious individuals seemed to experience no discomfort and even positive feelings during the period of contact restrictions. Our results support the assumption that neuroticism is a vulnerability factor in relation to psychological wellbeing but also show an influence of contact restrictions on extraverted individuals.

Here we show that visuo-tactile congruency indeed does not add to already high measures for body ownership on explicit measures, but does modulate movement behavior when walking in the laboratory. Specifically, participants who took ownership over a more corpulent virtual body with intact visuo-tactile congruency increased safety distances towards the laboratory's walls compared to participants who experienced the same illusion with deteriorated visuo-tactile congruency. This effect is in line with the body schema more readily adapting to a more corpulent body after receiving congruent tactile information. We conclude that the action-oriented, unconscious body schema relies more heavily on tactile information compared to more explicit aspects of body ownership.

A1 - Gromer, Daniel A1 - Pauli, Paul A1 - Hilger, Kirsten T1 - A virtual reality social conditioned place preference paradigm for humans: Does trait social anxiety affect approach and avoidance of virtual agents? JF - Frontiers in Virtual Reality N2 - Approach and avoidance of positive and negative social cues are fundamental to prevent isolation and ensure survival. High trait social anxiety is characterized by an avoidance of social situations and extensive avoidance is a risk factor for the development of social anxiety disorder (SAD). Therefore, experimental methods to assess social avoidance behavior in humans are essential. The social conditioned place preference (SCPP) paradigm is a well-established experimental paradigm in animal research that is used to objectively investigate social approach–avoidance mechanisms. We retranslated this paradigm for human research using virtual reality. To this end, 58 healthy adults were exposed to either a happy- or angry-looking virtual agent in a specific room, and the effects of this encounter on dwell time as well as evaluation of this room in a later test without an agent were examined. We did not observe a general SCPP effect on dwell time or ratings but discovered a moderation by trait social anxiety, in which participants with higher trait social anxiety spent less time in the room in which the angry agent was present before, suggesting that higher levels of trait social anxiety foster conditioned social avoidance. However, further studies are needed to verify this observation and substantiate an association with social anxiety disorder. We discussed the strengths, limitations, and technical implications of our paradigm for future investigations to more comprehensively understand the mechanisms involved in social anxiety and facilitate the development of new personalized treatment approaches by using virtual reality.

To this end, we (1) provide a taxonomy of rest breaks according to which empirical studies can be classified (e.g., by differentiating between long, short, and micro-rest breaks based on context and temporal properties). Then, we (2) evaluate the theorizing in both the basic and applied fields of research and explain how popular concepts (e.g., ego depletion model, opportunity cost theory, attention restoration theory, action readiness, etc.) relate to each other in contemporary theoretical debates. Here, we highlight differences between all these models in the light of two symbolic categories, termed the resource-based and satiation-based model, including aspects related to the dynamics and the control (strategic or non-strategic) mechanisms at work. Based on a critical assessment of existing methodological and theoretical approaches, we finally (3) provide a set of guidelines for both theory building and future empirical approaches to the experimental study of rest breaks. We conclude that a psychometrically advanced and theoretically focused research of rest and recovery has the potential to finally provide a sound scientific basis to eventually mitigate the adverse effects of ever increasing task demands on performance and well-being in a multitasking world at work and leisure.

In part, this may be caused by insufficiently standardized analysis methods that may be subject to state dependent variations in performance. In this work, we show how to easily adapt the two-layer feedforward neural network architecture provided by Huang1 to a behavioral classification problem as well as a physiological classification problem which would not be solvable in a standardized way using classical regression or “simple rule” approaches. In addition, we provide an example for a new research paradigm along with this standardized analysis method. This paradigm as well as the analysis method can be adjusted to any necessary modification or applied to other paradigms or research questions. Hence, we wanted to show that two-layer feedforward neural networks can be used to increase standardization as well as replicability and illustrate this with examples based on a virtual T-maze paradigm\(^{2−5}\) including free virtual movement via joystick and advanced physiological data signal processing.

However, the cognitive underpinnings of this effect and of rule violations in general have only attracted little scientific attention yet. In this study, we investigated whether cues of being observed not only reduce the likelihood of violating rules but also affect the underlying cognitive processes of such behavior when still putting a rule violation into action. Therefore, we applied a motion-tracking paradigm in which participants could violate a simple stimulus-response mapping rule while being faced with pictures of either open or closed eyes. In line with prior research, temporal and spatial measures of the participants' movements indicated that violating this rule induced substantial cognitive conflict. However, conflict during rulebreaking was not moderated by the eye stimuli. This outcome suggests that rule retrieval constitutes an automatic process which is not or is only barely influenced by situational parameters. Moreover, our results imply that the effect of perceived observation on rule conformity is driven by normative influences on decision-making instead of social facilitation of dominant action tendencies.

Participants moved a small cursor with their unseen hand twice to a large visual target object and then judged either the relative distance of the hand movements (Exp.1), or the relative number of dots that appeared in the two consecutive target objects (Exp.2) using a two-alternative forced choice method. During a learning phase, the numbers of dots that appeared in the target object were correlated with the hand movement distance. In Exp.1, we observed that after the participants were trained to expect many dots with larger hand movements, they judged movements made to targets with many dots as being longer than the same movements made to targets with few dots. In Exp.2, another group of participants who received the same training judged the same number of dots as smaller when larger rather than smaller hand movements were executed. When many dots were paired with smaller hand movements during the learning phase of both experiments, no significant changes in the perception of movements and of visual stimuli were observed. These results suggest that changes in the perception of body states and of external objects can arise when certain body characteristics co-occur with certain characteristics of the environment. They also indicate that the (dis)integration of multimodal perceptual signals depends not only on the physical or statistical relation between these signals, but on which signal is currently attended.

T1 - Towards robust in vivo quantification of oscillating biomagnetic fields using Rotary Excitation based MRI JF - Scientific Reports N2 - Spin-lock based functional magnetic resonance imaging (fMRI) has the potential for direct spatially-resolved detection of neuronal activity and thus may represent an important step for basic research in neuroscience. In this work, the corresponding fundamental effect of Rotary EXcitation (REX) is investigated both in simulations as well as in phantom and in vivo experiments. An empirical law for predicting optimal spin-lock pulse durations for maximum magnetic field sensitivity was found. Experimental conditions were established that allow robust detection of ultra-weak magnetic field oscillations with simultaneous compensation of static field inhomogeneities. Furthermore, this work presents a novel concept for the emulation of brain activity utilizing the built-in MRI gradient system, which allows REX sequences to be validated in vivo under controlled and reproducible conditions. Via transmission of Rotary EXcitation (tREX), we successfully detected magnetic field oscillations in the lower nano-Tesla range in brain tissue. Moreover, tREX paves the way for the quantification of biomagnetic fields.

Potential end-users with impaired vision, however, cannot use these BCIs efficiently and require a non-visual alternative. Both auditory and tactile paradigms have been developed but are often not sufficiently fast or accurate. Thus, it is particularly relevant to investigate if and how users can train and improve performance. We report data from 29 healthy participants who trained with a 4-choice tactile P300-BCI during five sessions. To identify potential training factors, we pre-post assessed the robustness of the BCI performance against increased workload in a dual task condition and determined the participants’ somatosensory sensitivity thresholds with a forced-choice intensity discrimination task. Accuracy (M = 79.2% to 92.0%) and tactually evoked P300 amplitudes increased significantly, confirming successful training. Pre-post somatosensory sensitivity increased, and workload decreased significantly, but results of the dual task condition remained inconclusive. The present study confirmed the previously reported feasibility and trainability of our tactile BCI paradigm within a multi-session design. Importantly, we provide first evidence of improvement in the somatosensory system as a potential mediator for the observed training effects.

T1 - Motivations underlying self-infliction of pain during thinking for pleasure JF - Scientific Reports N2 - Previous research suggested that people prefer to administer unpleasant electric shocks to themselves rather than being left alone with their thoughts because engagement in thinking is an unpleasant activity. The present research examined this negative reinforcement hypothesis by giving participants a choice of distracting themselves with the generation of electric shock causing no to intense pain. Four experiments (N = 254) replicated the result that a large proportion of participants opted to administer painful shocks to themselves during the thinking period. However, they administered strong electric shocks to themselves even when an innocuous response option generating no or a mild shock was available. Furthermore, participants inflicted pain to themselves when they were assisted in the generation of pleasant thoughts during the waiting period, with no difference between pleasant versus unpleasant thought conditions. Overall, these results question that the primary motivation for the self-administration of painful shocks is avoidance of thinking. Instead, it seems that the self-infliction of pain was attractive for many participants, because they were curious about the shocks, their intensities, and the effects they would have on them.

A1 - Scherbaum, Stefan A1 - Pittig, Andre T1 - Costly avoidance of Pavlovian fear stimuli and the temporal dynamics of its decision process JF - Scientific Reports N2 - Conflicts between avoiding feared stimuli versus approaching them for competing rewards are essential for functional behavior and anxious psychopathology. Yet, little is known about the underlying decision process. We examined approach-avoidance decisions and their temporal dynamics when avoiding Pavlovian fear stimuli conflicted with gaining rewards. First, a formerly neutral stimulus (CS+) was repeatedly paired with an aversive stimulus (US) to establish Pavlovian fear. Another stimulus (CS−) was never paired with the US. A control group received neutral tones instead of aversive USs. Next, in each of 324 trials, participants chose between a CS−/low reward and a CS+/high reward option. For the latter, probability of CS+ presentation (Pavlovian fear information) and reward magnitude (reward information) varied. Computer mouse movements were tracked to capture the decision dynamics. Although no more USs occurred, pronounced and persistent costly avoidance of the Pavlovian fear CS+ was found. Time-continuous multiple regression of movement trajectories revealed a stronger and faster impact of Pavlovian fear compared to reward information during decision-making. The impact of fear information, but not reward information, modestly decreased across trials. These findings suggest a persistently stronger weighting of fear compared to reward information during approach-avoidance decisions, which may facilitate the development of pathological avoidance.

The present study expands this research by exploring whether people also non-strategically detect information that threatens their social identity. Participants (N = 77) completed a task in which they had to respond to a “True” or “False” probe after reading true, false, identity-threatening, or non-threatening sentences. Replicating previous studies, participants reacted more slowly to a positive probe (“True”) after reading false (vs. true) sentences. Notably, participants also reacted more slowly to a positive probe after reading identity-threatening (vs. non-threatening) sentences. These results provide first evidence that identity-threatening information, just as false information, is detected at a very early stage of information processing and lends support to the notion of a routine, non-strategic identity-defense mechanism.

It was only in recent years that increased efforts have been made to organize available research findings and thereby bring back greater uniformity to the field of giftedness and gifted education. For example, Preckel et al.’s (2020) Talent Development in Achievement Domains (TAD) framework integrates theoretical perspectives and empirical knowledge from different parts of the field. It is general in concept and can be applied to a wide range of achievement domains. By specifically focusing on measurable psychological constructs as well as their relevance at different stages of the talent development process, Preckel et al.’s (2020) TAD framework is well suited as a starting point for generating more domain-specific talent development models. The present thesis represents one of the first attempts to empirically test the validity of Preckel et al.’s (2020) TAD framework in academic domains using longitudinal data. The longitudinal data came from a sample of former junior students at Julius-Maximilians-Universität (JMU) Würzburg who showed high academic achievement potential. There were two related research issues: Research Issue 1 first aimed to document in detail how the educational trajectories of former junior students unfold in the years following their Abitur. To this end, a follow-up was conducted among 208 young adults who had participated in the junior study program at JMU Würzburg between the winter semester of 2004/2005 and the summer semester of 2011. The design of the follow-up questionnaire was based on a series of research questions that had emerged from the relevant literature on junior study programs in Germany. The follow-up ran from October 2019 to February 2020. The data were analyzed descriptively and documented as a detailed report. The results of Research Issue 1 revealed that the former junior students continued to be academically (and later professionally) successful long after their school years. For example, at the time of the follow-up, almost all former junior students had earned a bachelor’s and a master’s degree, most often with notable academic successes (e.g., scholarships, awards/prizes). In addition, more than half of those who responded had begun or already completed a doctoral degree, also recording special academic accomplishments (e.g., scientific publications, scholarships). A significant proportion of the former junior students had already entered the workforce at the time of their response. A look at their current professional situation revealed an above-average expression of success indicators (e.g., income, professional status). The clear majority of the former junior students reported that, even in retrospect, they would choose to take part in the junior study program at JMU Würzburg again. Research Issue 2 aimed to determine the extent to which the structure of Preckel et al.’s (2020) TAD framework could be empirically validated in academic domains. The educational trajectories of 84 former junior students at JMU Würzburg who had chosen a subject from the same subject field in their regular studies as in their junior studies served as the data basis. The educational trajectories were compiled from the former junior students’ follow-up data and from their data on the selection process for the junior study program at JMU Würzburg. Combining the structural assumptions of Preckel et al.’s (2020) TAD framework with relevant insights from individual academic disciplines made it possible to derive hypotheses regarding potential predictors and indicators of the talent development stages aptitude, competence, and expertise in academic domains. Structural equation models were used for data analysis. The results of Research Issue 2 suggested that the talent development stages aptitude, competence, and expertise, while being predictive of each other in their chronological order, could be satisfactorily modeled using framework-compliant indicators in academic domains. In comparison, the talent development stage transformational achievement could not (yet) be modeled based on the longitudinal data. Among the hypothesized predictors, former junior students’ investigative interests and their metacognitive abilities reliably determined the talent development stages competence and expertise, whereas the remaining predictors did not make significant contributions. Taken together, the results of the present thesis suggest that the validity of Preckel et al.’s (2020) TAD framework can only be partially confirmed in academic domains. Unlike the postulated indicators, the predictors in Preckel et al.’s (2020) TAD framework do not seem to be easily generalizable to academic domains but to be highly specific with regard to the talent domain under consideration. Therefore, a natural progression of the present thesis would be to examine the structure of Preckel et al.’s (2020) TAD framework at the subordinate level of subject fields or even at the level of individual academic disciplines, for example. N2 - Der Bereich der (Hoch-)Begabung und Begabtenförderung galt aufgrund inkonsistenter Definitionen von Kernkonzepten lange Zeit als intern zersplittert (z.B., Ambrose et al., 2010; Coleman, 2006; McBee et al., 2012). Erst in den letzten Jahren sind vermehrt Bemühungen entstanden, bestehende Forschungsbefunde zu ordnen und dem Bereich der (Hoch-)Begabung und Begabtenförderung wieder zu mehr Einheitlichkeit zu verhelfen. Das Integrative Talententwicklungsmodell von Preckel et al. (2020) vereint beispielsweise theoretische Perspektiven und empirisches Wissen aus verschiedenen Teilen des Forschungsbereichs. Es ist allgemein konzipiert und kann auf eine Vielzahl von Leistungsdomänen angewendet werden. Durch eine gezielte Konzentration auf messbare psychologische Konstrukte sowie deren Relevanz auf unterschiedlichen Stufen der Talententwicklung ist das Integrative Talententwicklungsmodell von Preckel et al. (2020) gut als Ausgangspunkt für die Generierung domänenspezifischer Talententwicklungsmodelle geeignet. Die vorliegende Arbeit stellt einen der ersten Versuche dar, die Gültigkeit des Integrativen Talententwicklungsmodells von Preckel et al. (2020) in akademischen Domänen anhand längsschnittlicher Daten empirisch zu überprüfen. Die längsschnittlichen Daten stammten dabei aus einer Stichprobe ehemaliger Frühstudierender der Julius-Maximilians-Universität (JMU) Würzburg, die nachweislich über eine hohe akademische Leistungsfähigkeit verfügten. Es wurden zwei zusammenhängende Forschungsfragen betrachtet: Forschungsfrage 1 verfolgte zunächst das Ziel, die Bildungsverläufe ehemaliger Frühstudierender in den Jahren nach ihrem Abitur ausführlich zu dokumentieren. Dazu wurde eine Nachbefragung unter 208 jungen Erwachsenen durchgeführt, die im Zeitraum von Wintersemester 2004/2005 bis Sommersemester 2011 am Frühstudium der JMU Würzburg teilgenommen hatten. Die Gestaltung des Fragebogens für die Nachbefragung orientierte sich an einer Reihe von Fragestellungen, die sich aus der einschlägigen Literatur zum Frühstudium in Deutschland ergeben hatte. Der Erhebungszeitraum der Nachbefragung erstreckte sich von Oktober 2019 bis Februar 2020. Die Daten wurden in erster Linie deskriptiv ausgewertet und in Berichtsform dargestellt. Die Ergebnisse von Forschungsfrage 1 zeigten, dass die ehemaligen Frühstudierenden weit über ihre Schulzeit hinaus herausragende (akademische und berufliche) Leistungen erbrachten. So hatten zum Zeitpunkt der Nachbefragung beinahe alle Ehemaligen einen Bachelor- und Masterabschluss, meist mit beachtlichen akademischen Erfolgen (z.B. Stipendium, Auszeichnungen/Preise), erworben. Mehr als die Hälfte der ehemaligen Frühstudierenden hatte darüber hinaus eine Promotion begonnen oder bereits abgeschlossen und dabei ebenfalls außerordentliche akademische Erfolge (z.B. Publikationen, Stipendien) erzielt. Ein wesentlicher Teil der ehemaligen Frühstudierenden war zum Befragungszeitpunkt bereits ins Berufsleben eingetreten. Ein Blick auf ihre aktuelle berufliche Situation zeigte eine überdurchschnittliche Ausprägung von Erfolgsindikatoren (z.B. Einkommen, beruflicher Status). Die deutliche Mehrheit der ehemaligen Frühstudierenden gab an, dass sie sich auch rückblickend wieder für eine Teilnahme am Frühstudium der JMU Würzburg entscheiden würde. Forschungsfrage 2 untersuchte schließlich, inwieweit sich die Struktur des Integrativen Talententwicklungsmodells von Preckel et al. (2020) für akademische Domänen empirisch validieren lässt. Als Datengrundlage dienten die Bildungsverläufe von 84 ehemaligen Frühstudierenden der JMU Würzburg, die im Regelstudium ein Fach aus derselben Fächergruppe wie im Frühstudium belegt hatten. Die Bildungsverläufe wurden aus den Daten der Nachbefragung und aus den Daten des Auswahlverfahrens für das Frühstudium an der JMU Würzburg gewonnen. Eine Kombination der strukturellen Annahmen des Integrativen Talententwicklungsmodells von Preckel et al. (2020) mit relevanten Erkenntnissen aus der Talentforschung zu einzelnen Studienfächern machte es möglich, Hypothesen über potenzielle Prädiktoren und Indikatoren der Talententwicklungsstufen Begabung, Kompetenz und Expertise für akademische Domänen aufzustellen. Zur Datenanalyse wurden Strukturgleichungsmodelle herangezogen. Die Ergebnisse von Forschungsfrage 2 ließen darauf schließen, dass die Talententwicklungsstufen Begabung, Kompetenz und Expertise anhand modellkonformer Indikatoren in akademischen Domänen zufriedenstellend abgebildet werden können und sich in ihrer chronologischen Reihenfolge gegenseitig vorhersagen. Die Talententwicklungsstufe transformatorische Leistung konnte dagegen auf Basis der Daten (noch) nicht modelliert werden. Unter den potenziellen Prädiktoren sagten das forschungsbezogene Interesse sowie die metakognitiven Fähigkeiten der ehemaligen Frühstudierenden die Talententwicklungsstufen Kompetenz und Expertise verlässlich vorher. Die restlichen Prädiktoren leisteten keinen signifikanten Beitrag. Insgesamt weisen die Ergebnisse der vorliegenden Arbeit darauf hin, dass sich die Gültigkeit des Integrativen Talententwicklungsmodells von Preckel et al. (2020) in akademischen Domänen nur zum Teil bestätigen lässt. Im Gegensatz zu den postulierten Indikatoren scheinen die Prädiktoren des Integrativen Talententwicklungsmodells von Preckel et al. (2020) nicht einfach auf akademische Domänen übertragbar zu sein, sondern unter Umständen eine hohe Spezifität in Bezug auf die betrachtete Domäne der Talententwicklung aufzuweisen. Eine sinnvolle Fortsetzung der vorliegenden Arbeit würde somit darin bestehen, die Struktur des Integrativen Talententwicklungsmodells von Preckel et al. (2020) beispielsweise auf der untergeordneten Ebene von Fächergruppen oder sogar auf der Ebene einzelner Studienfächer zu untersuchen.

The EmpaToM is a validated social video task that allows for independent manipulation and assessment of the two capacities. First applications revealed that empathy and ToM are dissociable constructs on a neuronal as well as on a behavioral level. As the EmpaToM has been designed for the assessment of social understanding in adults, it has a high degree of complexity and comprises topics that are inadequate for minors. For this reason, we designed a new version of the EmpaToM that is especially suited to measure empathy and ToM in youths. In experiment 1, we successfully validated the EmpaToM-Y on the original EmpaToM in an adult sample (N = 61), revealing a similar pattern of results across tasks and strong correlations of all constructs. As intended, the performance measure for ToM and the control condition of the EmpaToM-Y showed reduced difficulty. In experiment 2, we tested the feasibility of the EmpaToM-Y in a group of teenagers (N = 36). Results indicate a reliable empathy induction and higher demands of ToM questions for adolescents. We provide a promising task for future research targeting inter-individual variability of socio-cognitive and socio-affective capacities as well as their precursors and outcomes in healthy minors and clinical populations.

However, these studies mainly used static and highly controlled stimulus material, thus revealing little about the robustness of attentional processes across diverging situations. Secondly, the influence of affective stimulus characteristics on visual exploration patterns remains poorly understood. Participants in the present study freely viewed a set of naturalistic, contextually rich video clips from a variety of settings that were capable of eliciting different moods. Using recordings of eye movements, we quantified to what degree social information, emotional valence and low-level visual features influenced gaze allocation using generalized linear mixed models. We found substantial and similarly large regression weights for low-level saliency and social information, affirming the importance of both predictor classes under ecologically more valid dynamic stimulation conditions. Differences in predictor strength between individuals were large and highly stable across videos. Additionally, low-level saliency was less important for fixation selection in videos containing persons than in videos not containing persons, and less important for videos perceived as negative. We discuss the generalizability of these findings and the feasibility of applying this research paradigm to patient groups.

Modulation of Revenge Interactions based on Opponent State Indicators of Suffering T1 - Im Angesicht des Feindes. Die Modulation von Racheinteraktionen basierend auf der Wahrnehmung von Leid Indikatoren innerhalb des Gegners N2 - Research on revenge often treats vengeful acts as singular one-way experiences, an approach which fails to account for the social nature and functions of revenge. This dissertation aims to integrate emotional punishment reactions into dynamic revenge sequences to investigate the affective and cognitive consequences of revenge within a social interaction. Exacting revenge can evoke intense affective consequences, from feelings of guilt to the genuine enjoyment of the suffering of others. In Chapter 2, affective responses towards suffering opponents and the regulation of aggression based on the appraisal of distinct suffering indicators were investigated. Results indicate that the observation of opponent pain evokes positive affect (measured via facial muscle contractions during the observation), which is followed by a downregulation of subsequent punishment. Both, positive affective reactions and the downregulation of punishment, were only observed following pain and not sadness expressions. Empathic distress, indexed by negative affective reactions, was only present following the observation of pain in non-provoking opponents. Showcasing the modulation of empathy related processes due to provocation and competition. In Chapter 3, a significant escalation of punishment, when being confronted with Schadenfreude, was observed. Results are interpreted as supporting the assumption that opponent monitoring processes inform subsequent action selection. The observation of opponent smiles led to imitation behavior (facial mimicry), which was partially attenuated due to previous provocation. The different functions of smile mimicry in the context of the aggressive competitive setting are discussed as containing simulation aspects (to aid in opponent understanding) and as a potential mirroring of dominance gestures, to avoid submission. In an additional series of studies, which are presented in Chapter 4, changes in memory of opponent faces following vengeful encounters were measured. Based on provocation, and punishment outcomes (pain & anger), face memory was distorted, resulting in more positive representations of opponents that expressed pain. These results are discussed as evidence of the impact of outcome appraisals in the formation of opponent representations and are theorized to aid empathy avoidance in future interactions. The comparison of desired and observed opponent states, is theorized to result in appraisals of the punishment outcomes, which evoke affective states, inform the action selection of subsequent punishments, and are integrated into the representation of the opponent in memory. Overall, the results indicate that suffering cues that are congruent with the chosen punishment action are appraised as positive, evoking an increase in positive affect. The emergence of positive affect during the observation of successful aggressive actions supports recent theories about the chronification of aggressive behavior based on reinforcement learning. To allow positive affect to emerge, affective empathic responses, such as distress, are theorized to be suppressed to facilitate the goal attainment process. The suffering of the opponent constitutes the proximate goal during revenge taking, which highlights the importance of a theoretical differentiation of proximate and ultimate goals in revenge to allow for a deeper understanding of the underlying motives of complex revenge behavior. N2 - Die bisherige Forschung zu den Mechanismen von Racheverhalten behandelt die Ausübung von Rache häufig als eine singuläre und unilaterale Erfahrung. Diese Herangehensweise berücksichtigt den sozialen Kontext und die Funktion von Rache nur unzureichend. Die vorliegende Dissertation zielt darauf ab, mittels empirischer Befunde emotionale Reaktionen in dynamische Rachesequenzen zu integrieren. Die Ausübung von Rache kann intensive affektive Zustände wie Schuldgefühle bis hin zu dem Empfinden von Freude über das Leid Anderer (Schadenfreude) auslösen. In Kapitel 2 werden Ergebnisse geschildert, welche die unterschiedlichen affektiven Reaktionen des Aggressors in Abhängigkeit zu Indikatoren des Leides des Gegners untersuchen. Im Rahmen der durchgeführten Studien wurde eine positive Reaktion (gemessen anhand von fazialen Muskelaktivierungen) während der Beobachtung von Schmerzausdrücken des Gegners beobachtet. Die positive affektive Reaktion geht mit einer Reduktion der darauffolgenden Strafe einher. Sowohl der positive Affekt als auch die Reduktion von Strafe wurden nur in Folge von Schmerzindikatoren und nicht nach Ausdrücken von Trauer beobachtet. Empathischer Stress nach ausgeführten Rachehandlungen, indiziert durch negative affektive Reaktionen, wurde nur gezeigt, nachdem nicht-provokative Gegner Schmerzreaktionen zeigten. Dies zeigt die Modulation von empathischen Prozessen in Abhängigkeit von Provokation und Konkurrenz. Kapitel 3 beschreibt die signifikante Eskalation von aggressiven Interaktionen durch eine Konfrontation mit Schadenfreude des Gegners während der Bestrafung. Dies lässt darauf schließen, dass die Beobachtung des Gegnerzustandes während der gesamten Interaktion die Wahl von Handlungen beeinflusst. Die Beobachtung des Lächelns beim Gegenüber führt zu Nachahmungsverhalten (faziale Mimikry), welches durch vorherige Provokation graduell abgeschwächt wird. Die verschiedenen Funktionen der Mimikry des Lächelns im Kontext einer aggressiv kompetitiven Situation enthalten Elemente von Simulation, zum besseren Verständnis der Gegnerreaktion, und dienen dazu als potenzielle Reaktion auf Dominanzverhalten Submission zu vermeiden. In einer weiteren Experimentalreihe, beschrieben in Kapitel 4, wird die Integration von erlebter Provokation und daraus resultierenden empfundenen Ärger in die Erinnerung an den Gegner demonstriert. Ergebnisse dieser Studienreine legen nahe, dass die Repräsentation des Gesichtes des Gegners in der Erinnerung basierend auf vorheriger Provokation und distinkten emotionalen gegnerischen Reaktionen auf Strafe (Schmerz & Ärger) systematisch variiert. Gegner, welche Schmerzreaktionen zeigten, wurden mit positiveren Gesichtskonfigurationen repräsentiert, im Gegensatz zu Gegnern, welche Ärger zeigten. Diese Ergebnisse werden als Belege für den Einfluss von Ergebnisbewertungen auf die Formation von Gegnerrepräsentationen und ihren potenziellen Nutzen für die Vermeidung von Empathie in zukünftigen Auseinandersetzungen diskutiert. Aus dem Abgleich zwischen dem gewünschten und beobachteten gegnerischen Reaktionen resultiert eine Bewertung des Erfolgs der Strafe. Dieser Bewertungsvorgang kann positive Affekte auslösen, die als Information in die Wahl der nächsten Handlung einfließen und die Repräsentation des Gegners in der Erinnerung verändern. Die Ergebnisse der hier dargestellten Studien deuten darauf hin, dass Signale des Leidens, die unmittelbar kongruent zu den zuvor gewählten Strafhandlungen sind, als positiv bewertet werden und somit zu einem unmittelbar erlebten positiven Affekt führen. Das Vorhandensein von positivem Affekt während der Beobachtung des leidenden Gegners nach erfolgreicher Bestrafung stimmt mit neueren Forschungsansätzen überein, die Verstärkungslernen als zentralen Prozess bei der Chronifizierung von aggressivem Verhalten postulieren. Das Auftreten von positivem Affekt wird durch die Herabsetzung von affektiv empathischen Prozessen gegenüber dem Gegner ermöglicht. Die Unterdrückung von affektiver Empathie erleichtert hierbei den Prozess der Zielerreichung. Das Leid des Gegners wird als proximales Ziel der Rachehandlung diskutiert. Eine Unterscheidung zwischen proximalen und distalen Zielen bei der Ausübung von Rache ermöglicht ein tieferes Verständnis für die zugrundeliegende Motive komplexen Racheverhaltens.

Here, we review studies that elucidate the actual content of social action representations and that explore factors that can distinguish action control processes involving social and inanimate action effects. Specifically, we address two hypotheses on how the social context can influence effect-based action control: first, by providing unique social features such as body-related, anatomical codes, and second, by orienting attention towards any relevant feature dimensions of the action effects. The reviewed empirical work presents a surprisingly mixed picture: while there is indirect evidence for both accounts, previous studies that directly addressed the anatomical account showed no signs of the involvement of genuinely social features in sociomotor action control. Furthermore, several studies show evidence against the differentiation of social and non-social action effect processing, portraying sociomotor action representations as remarkably non-social. A focus on enhancing the social experience in future studies should, therefore, complement the current database to establish whether such settings give rise to the hypothesized influence of social context.

These factors may be particularly relevant in contexts requiring social distancing, e.g., during the COVID-19 pandemic or in states of immunodeficiency. We present the Loneliness and Isolation during Social Distancing (LISD) Scale. Extending existing measures, the LISD scale measures both state and trait aspects of loneliness and isolation, including indicators of social connectedness and support. In addition, it reliably predicts individual differences in anxiety and depression. Data were collected online from two independent samples in a social distancing context (the COVID-19 pandemic). Factorial validation was based on exploratory factor analysis (EFA; Sample 1, N = 244) and confirmatory factor analysis (CFA; Sample 2, N = 304). Multiple regression analyses were used to assess how the LISD scale predicts state anxiety and depression. The LISD scale showed satisfactory fit in both samples. Its two state factors indicate being lonely and isolated as well as connected and supported, while its three trait factors reflect general loneliness and isolation, sociability and sense of belonging, and social closeness and support. Our results imply strong predictive power of the LISD scale for state anxiety and depression, explaining 33 and 51% of variance, respectively. Anxiety and depression scores were particularly predicted by low dispositional sociability and sense of belonging and by currently being more lonely and isolated. In turn, being lonely and isolated was related to being less connected and supported (state) as well as having lower social closeness and support in general (trait). We provide a novel scale which distinguishes between acute and general dimensions of loneliness and social isolation while also predicting mental health. The LISD scale could be a valuable and economic addition to the assessment of mental health factors impacted by social distancing.

Here, MAOA methylation was analyzed via direct sequencing of sodium bisulfite-treated DNA extracted from blood cells before and after a 2-week exposure therapy in a sample of n = 28 female patients with acrophobia as well as in n = 28 matched healthy female controls. Clinical response was measured using the Acrophobia Questionnaire and the Attitude Towards Heights Questionnaire. The functional relevance of altered MAOA methylation was investigated by luciferase-based reporter gene assays. MAOA methylation was found to be significantly decreased in patients with acrophobia compared with healthy controls. Furthermore, MAOA methylation levels were shown to significantly increase after treatment and correlate with treatment response as reflected by decreasing Acrophobia Questionnaire/Attitude Towards Heights Questionnaire scores. Functional analyses revealed decreased reporter gene activity in presence of methylated compared with unmethylated pCpGfree_MAOA reporter gene vector constructs. The present proof-of-concept psychotherapy-epigenetic study for the first time suggests functional MAOA methylation changes as a potential epigenetic correlate of treatment response in acrophobia and fosters further investigation into the notion of epigenetic mechanisms underlying fear extinction.

Therefore, research on the underlying mechanisms of pain processing and modulation is necessary and warranted. One crucial part of this pain research includes identifying resilience factors that protect from chronic pain development and enhance its treatment. The ability to use emotion regulation strategies has been suggested to serve as a resilience factor, facilitating pain regulation and management. Acceptance has been discussed as a promising pain regulation strategy, but results in this domain have been mixed so far. Moreover, the allocation of acceptance in Gross’s (1998) process model of emotion regulation has been under debate. Thus, comparing acceptance with the already established strategies of distraction and reappraisal could provide insights into underlying mechanisms. This dissertation project consisted of three successive experimental studies which aimed to investigate these strategies by applying different modalities of individually adjusted pain stimuli of varying durations. In the first study (N = 29), we introduced a within-subjects design where participants were asked to either accept (acceptance condition) or react to the short heat pain stimuli (10 s) without using any pain regulation strategies (control condition). In the second study (N = 36), we extended the design of study 1 by additionally applying brief, electrical pain stimuli (20 ms) and including the new experimental condition distraction, where participants should distract themselves from the pain experience by imagining a neutral situation. In the third study (N = 121), all three strategies, acceptance, distraction, and reappraisal were compared with each other and additionally with a neutral control condition in a mixed design. Participants were randomly assigned to one of three strategy groups, including a control condition and a strategy condition. All participants received short heat pain stimuli of 10 s, alternating with tonic heat pain stimuli of 3 minutes. In the reappraisal condition, participants were instructed to imagine the pain having a positive outcome or valence. The self-reported pain intensity, unpleasantness, and regulation ratings were measured in all studies. We further recorded the autonomic measures heart rate and skin conductance continuously and assessed the habitual emotion regulation styles and pain-related trait factors via questionnaires. Results revealed that the strategies acceptance, distraction, and reappraisal significantly reduced the self-reported electrical and heat pain stimulation with both durations compared to a neutral control condition. Additionally, regulatory efforts with acceptance in study 2 and with all strategies in study 3 were reflected by a decreased skin conductance level compared to the control condition. However, there were no significant differences between the strategies for any of the assessed variables. These findings implicate similar mechanisms underlying all three strategies, which led to the proposition of an extended process model of emotion regulation. We identified another sequence in the emotion-generative process and suggest that acceptance can flexibly affect at least four sequences in the process. Correlation analyses further indicated that the emotion regulation style did not affect regulatory success, suggesting that pain regulation strategies can be learned effectively irrespective of habitual tendencies. Moreover, we found indications that trait factors such as optimism and resilience facilitated pain regulation, especially with acceptance. Conclusively, we propose that acceptance could be flexibly used by adapting to different circumstances. The habitual use of acceptance could therefore be considered a resilience factor. Thus, acceptance appears to be a promising and versatile strategy to prevent the development of and improve the treatment of various chronic pain disorders. Future studies should further examine factors and circumstances that support effective pain regulation with acceptance. N2 - Schmerzen und chronische Schmerzstörungen, welche eine enorme Belastung für Betroffene und das Gesundheitssystem darstellen, zählen zu den häufigsten Gründen für eine medizinische Behandlung. Die Erforschung von Mechanismen der Schmerzverarbeitung und -modulation ist daher hochgradig relevant. Ein Teil dieser Schmerzforschung befasst sich mit der Ermittlung von Resilienzfaktoren, die der Chronifizierung von Schmerzen vorbeugen und deren Behandlungen erleichtern sollen. Emotionsregulationsstrategien können als solche Resilienzfaktoren fungieren und die Behandlung von Schmerzen unterstützen. Studien zur Strategie Akzeptanz zeigten bereits Hinweise auf eine effektive Schmerzregulation, jedoch ist die Befundlage hinsichtlich der Effektivität noch uneindeutig. Eine weitere Unklarheit besteht bei der Einordnung von Akzeptanz als eine antezedent- oder reaktionsfokussierte Strategie in Gross Prozessmodel der Emotionsregulation (1998). Ein direkter Vergleich zwischen Akzeptanz und den bereits intensiv beforschten Strategien Ablenkung und Neubewertung könnte dabei Klarheit über die zugrunde liegenden Mechanismen und deren Einordnung schaffen. Das Ziel des aktuellen Dissertationsprojekts bestand daher darin, diese drei Strategien einander experimentell in einem akuten Schmerzkontext gegenüberzustellen. Zu diesem Zweck wurden drei aufeinanderfolgende Studien mit gesunden Probanden durchgeführt, die jeweils individuell eingestellte Schmerzreize erhielten. In der ersten Studie (N = 29) im Within-Design wurden den Probanden kurze Hitzeschmerzreize von 10 s verabreicht, welche sie akzeptieren (Akzeptanzbedingung) oder auf welche sie reagieren sollten, ohne eine Strategie anzuwenden (Kontrollbedingung). In der zweiten Studie (N = 36) wurde Studie 1 um zwei Bedingungen erweitert, indem phasische, elektrische Schmerzreize von 20 ms zum Within-Design hinzugefügt wurden. Darüber hinaus sollten sich die Versuchspersonen zusätzlich mithilfe neutraler Vorstellungen von den Schmerzreizen ablenken (Ablenkungsbedingung). In der dritten Studie (N = 121) wurden alle drei Strategien – Akzeptanz, Ablenkung und Neubewertung – einander sowie einer neutralen Kontrollbedingung in einem gemischten Within-Between-Design gegenübergestellt. Die Teilnehmenden wurden zufällig einer der drei Strategiegruppen zugewiesen, welche jeweils die Kontrollbedingung und eine der drei Strategiebedingungen enthielt. Die Probanden erhielten in allen Gruppen sowohl kurze, 10-sekündige als auch lange, 3-minütige Hitzeschmerzreize. Bei der Strategie Neubewertung sollten sich die Probanden vorstellen, dass der Hitzereiz eine positive Wirkung hätte. In allen Studien gaben die Probanden nach jedem Durchgang an, wie schmerzhaft und unangenehm sie die Schmerzreize erlebt hatten und wie gut es ihnen gelungen war, mit der jeweiligen Strategie zu regulieren. Außerdem wurden die peripherphysiologischen Messverfahren Herzrate und Hautleitfähigkeit als Schmerzkorrelate kontinuierlich aufgezeichnet. Zuletzt wurden die Emotionsregulationsstile und schmerzrelevante Persönlichkeitsfaktoren anhand von Fragebögen erfasst. Über alle Studien zeigte sich, dass die drei Strategien Akzeptanz, Ablenkung und Neubewertung die selbstberichtete Wahrnehmung der kurzen und langen Hitzeschmerzreize sowie der phasischen elektrischen Reize im Vergleich zur Kontrollbedingung signifikant verringerten. Des Weiteren deutete eine signifikant verminderte Hautleitfähigkeit in der Akzeptanzbedingung in Studie 2 und in allen Strategiebedingungen in Studie 3 – verglichen mit der Kontrollbedingung – auf peripherphysiologisch erkennbare Regulationsprozesse hin. Zwischen den Strategien ließen sich jedoch bei keiner der Messvariablen signifikante Unterschiede finden. Dieses Ergebnis könnte auf ähnliche, den Strategien zugrunde liegende Mechanismen hindeuten, sodass im Rahmen des Dissertationsprojekts ein erweitertes Prozessmodell der Emotionsregulation aufgestellt wurde. Dabei wurde der emotionsgenerierende Prozess um einen Schritt erweitert und es wurden mindestens vier Positionen vorgeschlagen, an welchen Akzeptanz flexibel ansetzen könnte. Korrelationsanalysen ergaben außerdem, dass der Emotionsregulationsstil keinen Einfluss auf den Regulationserfolg hatte, was darauf hindeutet, dass Schmerzregulationsstrategien unabhängig von gewohnheitsmäßigen Tendenzen effektiv erlernt werden können. Darüber hinaus gab es Hinweise darauf, dass höhere Ausprägungen von Persönlichkeitsfaktoren wie Optimismus und Resilienz zu einer effektiveren Schmerzregulation insbesondere mit Akzeptanz führen können. Insgesamt scheint Akzeptanz flexibel einsetzbar und anpassungsfähig zu sein, was sie zu einem Resilienzfaktor im alltäglichen Gebrauch sowie zu einer vielversprechenden Strategie in der Prävention und Behandlung chronischer Schmerzerkrankungen macht. Zukünftige Forschung sollte daher die Faktoren und Umstände untersuchen, die zu einer wirksamen Schmerzregulation mit Akzeptanz beitragen können.

In learning from texts, the benefits of distribution might even go beyond distributed practice, i.e. distribution of repeated materials. In realistic learning scenarios as for example school or university learning, the reader might read multiple texts that not repeat but complement each other. Therefore, distribution might also be implemented between multiple texts and benefit long-term learning in analogy to distributed practice. The assumption of beneficial effects of this distributed learning can be deduced from theories about text comprehension as the landscape model of reading (van den Broek et al., 1996) in combination with theories of desirable difficulties in general (R. A. Bjork & Bjork, 1992) and distributed practice in particular (Benjamin & Tullis, 2010). This dissertation aims to investigate (1) whether distributed learning benefits learning; (2) whether the amount of domain-specific prior knowledge moderates the effects of distribution, (3) whether distributed learning affects the learner’s meta-cognitive judgments in analogy to distributed practice and (4) whether distributed practice is beneficial for seventh graders in learning from single text. In Experiment 1, seventh graders read two complementary texts either massed or distributed by a lag of one week between the texts. Learning outcomes were measured immediately after reading the second text and one week later. Judgements of learning were assessed immediately after each text. Experiment 2 replicated the paradigm of Experiment 1 while shortening the lag between the texts in the distributed condition to 15 min. In both experiments, an interaction effect between learning condition (distributed vs. massed) and retention interval (immediate vs. delayed) was found. In the distributed condition, the participants showed no decrease in performance between the two tests, whereas participants in the massed condition did. However, no beneficial effects were found in the delayed test for the distributed condition but even detrimental effects for the distributed condition in the immediate test. In Experiment 1, participants in the distributed condition perceived learning as less difficult but predicted lower success than the participants in the massed condition. Experiment 3 replicated the paradigm of Experiment 1 with university students in the laboratory. In the preregistered Experiment 4, an additional retention interval of two weeks was realized. In both experiments, the same interaction between learning condition and retention interval was found. In Experiment 3, the participants in the distributed condition again showed no decrease in performance between the two tests, whereas participants in the massed condition did. However, even at the longer retention interval in Experiment 4, no beneficial effects were found for the distributed condition. Domain-specific prior knowledge was positively associated with test performance in both experiments. In Experiment 4, the participants with low prior knowledge seemed to be impaired by distributed learning, whereas no difference was found for participants with medium or high prior knowledge. In the preregistered Experiment 5, seventh graders read a single text twice. The rereading took place either massed or distributed with one week. Immediately after rereading, judgements of learning were assessed. Learning outcomes were assessed four min after second reading or one week later. Participants in the distributed condition predicted lower learning success than participants in the massed condition. An interaction effect between learning condition and retention interval was found, but no advantage for the distributed condition. Participants with low domain-specific prior knowledge showed lower performance in short-answer questions in the distributed condition than in the massed condition. Overall, the results seem less encouraging regarding the effectiveness of distribution on learning from single and multiple texts. However, the experiments reported here can be perceived as first step in the realistic investigation of distribution in learning from texts. N2 - Verteiltes Üben ist eine bekannte Lernstrategie, deren positiver Effekt auf die langfristigen Behaltensleistung in vielen Experimenten gezeigt wurde. Beim Lernen mit Texten können die Vorteile der Verteilung von Lerninhalten sogar über verteiltes Üben, also die Verteilung von sich wiederholenden Materialien, hinausgehen. In realistischen Lernszenarien, wie zum Beispiel Lernen in der Schule oder Universität, werden multiple Texte gelesen, die einander nicht wiederholen, sondern ergänzen. Verteilung im Sinne des verteilten Übens könnte demensprechend auch zwischen diesen multiplen Texten eingesetzt werden und analog zum verteilten Üben langfristiges Behalten fördern. Annahmen über eine Wirksamkeit dieses sogenannten verteilten Lernens können von Theorien zum Textverständnis wie zum Beispiel dem Landscape Model of Reading (van den Broek et al., 1996) in Kombination mit Theorien zu wünschenswerten Erschwernissen im Allgemeinen (R. A. Bjork & Bjork, 1992) und verteiltem Üben im Besonderen (Benjamin & Tullis, 2010) abgeleitet werden. In dieser Dissertation soll untersucht werden, (1) ob verteiltes Lernen Behalten fördert, (2) ob die Ausprägung des domänenspezifischen Vorwissens die Effekte des verteilten Lernens moderiert, (3) ob verteiltes Lernen die meta-kognitive Beurteilung des Lernprozesses des Lernenden beeinflusst und (4) ob verteiltes Üben für 7. Klässler*innen beim Lernen mit einzelnen Texten vorteilhaft ist. Im ersten Experiment lasen 7. Klässler*innen zwei komplementäre Texte entweder massiert oder verteilt mit einem Abstand (lag) von einer Woche. Die Behaltensleistung wurde unmittelbar nach dem Lesen des zweiten Textes und eine Woche später erfasst. Die Beurteilung des Lernprozesses wurde direkt nach dem Lesen eines Textes erhoben. Experiment 2 replizierte das Paradigma von Experiment 1, wobei der Abstand zwischen den Texten in der verteilten Bedingung auf 15 Min reduziert wurde. In beiden Experimenten wurde eine Interaktion zwischen der Lernbedingung (massiert vs. verteilt) und dem Behaltensintervall (unmittelbar vs. später) gefunden. In der verteilten Bedingung zeigten die Teilnehmenden keine Verringerung in der Leistung zwischen den beiden Tests, die Teilnehmenden in der massierten Bedingung jedoch schon. Trotzdem wurden keine Vorteile des verteilten Lernens beim späteren Test gefunden. Stattdessen zeigten sich unmittelbar nach dem Lernen Nachteile des verteilten Lernens. In Experiment 1 nahmen die Teilnehmenden der verteilten Bedingung das Lernen als weniger schwierig wahr, erwarteten jedoch geringeren Lernerfolg als Teilnehmende der massierten Bedingung. Experiment 3 replizierte das Paradigma von Experiment 1 mit Studierenden in einem Laborsetting. In dem präregistrierten Experiment 4 wurde ein Behaltensintervall von zwei Wochen ergänzt. In beiden Experimenten fand sich eine ähnliche Interaktion zwischen Lernbedingung und Behaltensintervall. In Experiment 3 zeigten die Teilnehmenden in der verteilten Bedingung erneut keine Verringerung in der Leistung zwischen den zwei Tests, in der massierten Bedingung jedoch schon. Es fanden sich jedoch keine Vorteile des verteilten Lernens, auch nicht nach dem längeren Behaltensintervall in Experiment 4. Domänenspezifisches Vorwissen stand in beiden Experimenten in einem positiven Zusammenhang mit der Behaltensleistung. In Experiment 4 zeigten die Teilnehmenden mit geringem Vorwissen geringere Behaltensleistungen, wenn sie verteilt lernten, während keine derartigen Unterschiede für Teilnehmende mit mittlerem oder hohem Vorwissen gefunden wurden. Im präregistrierten Experiment 5 lasen 7. Klässler*innen einen einzelnen Text zweimal. Das zweite Lesen erfolgte hier entweder unmittelbar (massiert) oder nach einer Woche (verteilt). Unmittelbar nach dem zweiten Lesen wurden die Beurteilung des Lernprozesses erhoben. Die Behaltensleistung wurde 4 Minuten oder eine Woche nach dem zweiten Lesen erfasst. Teilnehmende in der verteilten Bedingung erwarteten geringeren Lernerfolg als Teilnehmende in der massierten Bedingung. Es wurde ein Interaktionseffekt zwischen der Lernbedingung und dem Behaltensintervall gefunden, aber kein Vorteil für die verteilte Bedingung. In der verteilten Bedingung zeigten Teilnehmende mit geringem Vorwissen geringere Leistung bei Fragen im Kurzantwortformat als vergleichbare Teilnehmende in der massierten Bedingung. Zusammenfassend wirken diese Ergebnisse wenig vielversprechend bezüglich der Wirksamkeit des verteilten Lernens und Übens mit einzelnen und multiplen Texten. Trotzdem sind die hier berichteten Experimente als ein erster Schritt zur Untersuchung des Verteilungseffektes beim Lernen mit Texten in realistischen Lernszenarien zu betrachten.

In this task, the participants have to decide which two of four rotated figures match the target figure. The dependent measures were performance speed and accuracy. In our exploratory investigation, we further examined midline frontal theta band activation, parietal alpha band activation, and parietal alpha band asymmetry in EEG as indicator for the chosen rotation strategy. Additionally, we explored the gender influence on performance and EEG activation, although a very small female sample section was given. The expected gender difference concerning performance accuracy was negated by expertise in pen and paper role-playing women, while the gender-specific difference in performance speed was preserved. Moreover, gender differences concerning electro-cortical measures revealed differences in rotation strategy, with women using top-down strategies compared to men, who were using top-down strategies and active inhibition of associative cortical areas. These strategy uses were further moderated by expertise, with higher expertise leading to more pronounced activation patters, especially during successful performance. However, due to the very limited sample size, the findings of this explorative study have to be interpreted cautiously.

However, not all readers are able to adequately understand texts or decode individual words. Findings from the Progress in International Reading Literacy Study (PIRLS; German: IGLU) show that about one fifth of fourth graders can only establish coherence at the local level, and in some cases they only have a rudimentary understanding of the text they read (Bremerich-Vos et al., 2017). In addition, these reading deficits persist and have a negative impact on academic and professional success (Jimerson, 1999). Therefore, identifying the causes of these deficits and creating opportunities for interventions at an early stage is an important research objective. The aim of this dissertation was to examine the relationship between the aspects of reading fluency and their influence on reading comprehension. Despite the increasing scientific interest in reading fluency in recent years, a research gap still exists in the relationship between word recognition accuracy and both speed and the relevance of prosodic patterns for reading comprehension. Study 1 investigated whether German fourth graders (N = 826) were required to reach a certain word-recognition accuracy threshold before their word-recognition speed improved. In addition, a sub-sample (n = 170) with a pre-/posttest design was examined to assess the extent that the existing word-recognition accuracy can influence the effects of a syllable-based reading intervention on word-recognition accuracy and word-recognition speed. Results showed that word-recognition speed improved after children achieved a word-recognition accuracy of 71%. A positive intervention effect was also found on word-recognition accuracy for children who were below the 71% threshold before the intervention, whereas the intervention effect on word-recognition speed was positive for all children. However, a positive effect on reading comprehension was only found for children who were above the 71% threshold before the intervention. Study 2 investigated the relationship between word-recognition accuracy threshold and word-recognition speed shown in the first study in a longitudinal design with German students (N = 1,095). Word-recognition accuracy and speed were assessed from the end of Grade 1 to 4, whereas reading comprehension was assessed from the end of Grade 2 to 4. The results showed that the developmental trajectories of word recognition speed and reading comprehension were steeper in children who reached the word-recognition accuracy threshold by the end of the first grade than in children who later reached or had not reached this threshold. In Study 3, recurrence analysis (RQA) was used to extract prosodic patterns from reading recordings of struggling and skilled readers in the second (n = 67) and fourth grade (n = 69) and was used for the classification into struggling and skilled readers. In addition, the classification based on the prosodic patterns from the recurrence quantification analysis was compared with the classification of prosodic features from the manual transcription of the reading recordings. The results showed that second-grade struggling readers have lengthier pauses within or between words and take more time between pauses on average, whereas fourth-grade struggling readers spend more time between recurring stresses and have multiple diverse patterns in pitch and more recurring accents. Although the recurrence analysis had a good goodness of fit and provided additional information about the relationship of prosody with reading comprehension, the model using prosodic features from transcription had a better fit. In summary, the three studies in this dissertation provide four important insights into reading fluency in German. First, a threshold in word-recognition accuracy must be achieved before word-recognition speed improves. Second, the earlier this accuracy level is reached, the greater the gain in word-recognition speed and reading comprehension. Third, the intervention effects of a primary school reading intervention are influenced by the accuracy level. Fourth, although incorrect pauses within or between words play an important role in identifying and describing struggling readers in second grade, the importance of prosodic patterns increases in fourth grade. N2 - Lesefähigkeiten zählen zu den wichtigsten Grundfertigkeiten in der heutigen Gesellschaft. Jedoch gelingt es nicht allen Lesern und Leserinnen Texte angemessen zu verstehen oder einzelne Wörter zu dekodieren. Erkenntnisse der Internationale Grundschul-Lese-Untersuchung (PIRLS; Deutsch: IGLU) belegen, dass etwa ein Fünftel der Viertklässler und Viertklässlerinnen Kohärenz nur auf lokaler Ebene herstellen können und in manchen Fällen nur über ein rudimentäres Verständnis des gelesenen Textes verfügen (Bremerich-Vos et al., 2017). Außerdem bleiben diese Lesedefizite bestehen und haben einen negativen Einfluss auf den schulischen und beruflichen Erfolg (Jimerson, 1999). Deshalb ist es wichtig die Ursachen dieser Defizite zu identifizieren und frühzeitig Möglichkeiten für Interventionen zu schaffen. Ziel der vorliegenden Dissertation war es, den Zusammenhang zwischen den Teilaspekten der Leseflüssigkeit und deren Einfluss auf das Leseverständnis näher zu untersuchen. Trotz der zunehmenden wissenschaftlichen Beschäftigung mit der Leseflüssigkeit in den letzten Jahren, besteht hier eine Forschungslücke sowohl bezüglich des Zusammenhangs zwischen Worterkennungsgenauigkeit und -geschwindigkeit als auch bezüglich der Relevanz prosodischer Muster für das Leseverständnis. In Studie 1 wurde untersucht, ob deutsche Viertklässler und Viertklässlerinnen (N = 826) eine bestimmte Worterkennungsgenauigkeitsschwelle erreichen müssen, bevor sich ihre Worterkennungsgeschwindigkeit verbessert. Darüber hinaus wurde in einer Teilstichprobe (n = 170) mit einem Prä-/Posttest Design untersucht, inwiefern die bestehende Worterkennungsgenauigkeit die Effekte einer silbenbasierten Leseintervention auf die Worterkennungsgenauigkeit und Worterkennungsgeschwindigkeit beeinflussen kann. Die Ergebnisse zeigten, dass die Worterkennungsgeschwindigkeit sich verbesserte, nachdem die Kinder eine Worterkennungsgenauigkeit von 71% erreichten. Zudem zeigten sich ein positiver Interventionseffekt auf die Worterkennungsgenauigkeit für die Kinder, die vor der Intervention unter der 71% Schwelle lagen. Auf die Worterkennungsgeschwindigkeit ergab sich für alle Kinder ein positiver Interventionseffekt. Auf das Leseverständnis hingegen zeigte sich nur für die Kinder, die vor der Intervention über der 71% Schwelle lagen, ein positiver Effekt. Studie 2 untersuchte den in der ersten Studie aufgezeigten Zusammenhang zwischen Worterkennungsgenauigkeitsschwelle und Worterkennungsgeschwindigkeit in einem längsschnittlichen Design mit deutschen Schülerinnen und Schüler (N = 1,095). Die Worterkennungsgenauigkeit und -geschwindigkeit wurden von Ende der Jahrgangsstufe 1 bis Jahrgangsstufe 4 erfasst, während das Leseverständnis von Ende der Jahrgangsstufe 2 bis Jahrgangsstufe 4 erfasst wurde. Die Ergebnisse zeigten, dass die Entwicklungsverläufe der Worterkennungsgeschwindigkeit und des Leseverständnisses bei Kindern, die die Worterkennungsgenauigkeitsschwelle bis Ende der Jahrgangsstufe 1 erreichten, steiler waren als bei Kindern, die diese Schwelle erst später oder gar nicht erreichten. In Studie 3 wurden mit Hilfe der Rekurrenzanalyse (RQA) prosodische Muster aus der Leseaufnahmen leseschwacher und -starker Kinder der Jahrgangsstufe 2 (n = 67) und der Jahrgangsstufe 4 (n = 69) extrahiert und für die Klassifikation in leseschwach und lesestark verwendet. Darüber hinaus wurde die Klassifikation anhand der prosodischen Muster aus der Rekurrenzanalyse mit der Klassifikation prosodischer Merkmale aus der manuellen Transkription der Leseaufnahmen verglichen. Die Ergebnisse zeigten, dass leseschwache Kinder der Jahrgangsstufe 2 längere Pausen innerhalb oder zwischen einzelnen Wörtern machen und im Durchschnitt mehr Zeit zwischen Pausen verstreichen lassen, während leseschwache Kinder der Jahrgangsstufe 4 mehr Zeit zwischen wiederkehrende Betonungen verstreichen lassen, viele Muster bei der Tonhöhe aufweisen und häufiger wiederkehrende Betonungen zeigen. Obwohl die Rekurrenzanalyse eine gute Anpassungsgüte hatte und zusätzliche Informationen zu dem Zusammenhang der Prosodie mit dem Leseverständnis lieferte, ergab sich für das Model mit den prosodischen Merkmalen aus der Transkription eine bessere Anpassungsgüte. Zusammenfassend liefern die drei Studien der vorliegenden Dissertation vier bedeutsame Erkenntnisse bezüglich der Leseflüssigkeit im Deutschen. Erstens: Es gibt eine gewisse Schwelle bei der Worterkennungsgenauigkeit, die erreicht werden muss, bevor sich die Worterkennungsgeschwindigkeit verbessert. Zweitens: Je früher diese Genauigkeitsschwelle erreicht wird, desto stärker ist der Zuwachs in der Worterkennungsgeschwindigkeit und im Leseverständnis. Drittens: Die Interventionseffekte einer Leseintervention in die Grundschule werden von der Genauigkeitsschwelle beeinflusst. Viertens: Während inkorrekte Pausen innerhalb oder zwischen einzelnen Wörtern eine wichtige Rolle für die Identifikation und Beschreibung von leseschwachen Kindern in die Jahrgangsstufe 2 spielen, nimmt die Bedeutung der prosodischen Muster in der Jahrgangsstufe 4 zu.

Most importantly, practicing test questions has been found to outperform restudy even when no additional information about the correct answers was provided to practice test takers, rendering practice tests effective and efficient in fostering retention of learning content. Since 15 years, additional scientific attention is devoted to this memory phenomenon and additional research investigated to what extend practicing test questions is relevant in real-world educational settings. This dissertation first presents the evidence for testing effects in applied educational settings by presenting key publications and presenting findings from a methodological review conducted for this purpose. Within this dissertation, theories are presented why practicing test questions should benefit learning in real-world educational settings even without the provision of additional information and key variables for the effectiveness of practicing test questions are presented. Four studies presented in this dissertation aimed at exploring these assumptions in actual university classrooms while also trying to implement new methods of practicing learning content and thus augment course procedures. Findings from these studies—although not often consistent—will be incorporated and interpreted in the light of the theoretical accounts on the testing effect. The main conclusion that can be drawn from this dissertation is that, given the right circumstances, practicing test questions can elicit beneficial effects on the retention of learning content that are independent of additional information and thus taking a practice test per se, can foster retention of real-world learning content. N2 - Seit einem Jahrhundert wird die positive Wirkung von Abrufübungen auf das Behalten gelernter Inhalte untersucht. Diese Untersuchungen belegen durchgängig, dass Abrufübungen für das Behalten förderlicher sind als vergleichbare Lernaktivitäten wie beispielsweise nochmaliges Lesen (Der Testungseffekt). Der Testungseffekt ist besonders bedeutsam wenn er in Settings untersucht wird in denen keine Informationen über die Richtigkeit des abgelegten Tests an die Lernenden gegeben werden und somit belegen, dass Abrufübungen nicht nur effektive sondern auch effiziente Methoden der Behaltensförderung darstellen. Seit 15 Jahren intensiviert sich das wissenschaftliche Interesse am Testungseffekt und immer mehr Forschung untersucht auch das Ausmaß der Übertragbarkeit auf reale Lernumgebungen. Diese Dissertation stellt zuerst Befunde aus Untersuchungen des Testungseffekts in angewandten Lernsettings dar, wobei zentrale Studien besprochen werden und hier ein eigens zu diesem Zweck angestelltes methodisches Review vorgestellt wird. Innerhalb der Dissertationen werden Theorien erläutert, warum Abrufübungen in realen Lernsettings das Behalten auch ohne zusätzliche Darbietung der korrekten Antwort fördern sollten und welche Variablen dafür essentiell sind. In dieser Dissertation warden zudem vier Studien präsentiert, die diese Variablen in universitären Lernumgebungen untersuchten, teilweise mit dem Ziel, Abrufübungen noch effektiver zu machen. Die gewonnenen Erkenntnisse aus diesen vier Studien—obwohl sie nicht immer konsistent sind—werden abschließend diskutiert und in Bezug zu den vorgestellten Theorien gesetzt. Eine zetrale Schlussfolgerung aus den vorgestellten Studien ist die Erkenntnis, dass unter den richtigen Bedingungen Abrufübungen den Testungseffekt hervorrufen können, die unabhängig von zusätlicher Information sind und dass es demnach die Abrufübung per se ist, die zum Behalten gelernter Information beiträgt.

During the construction of a mental model, validation implicitly assesses the plausibility of incoming information by checking its consistency with world knowledge, prior beliefs, and contextual information (e.g., the broader discourse context). However, research on potential influences that shape validation processes has just started. One branch of research is investigating how world knowledge and contextual information contribute to integration and validation. World knowledge usually influences validation more strongly because information plausibility is the primary criterion for validation, but strong contextual information can yield influences as well. Contextual information that may be specifically relevant for routine validation is the credibility of a source providing text information. Source credibility bears a strong conceptual relationship to the validity of information. However, a dearth of research has investigated joint effects of plausibility and source credibility for routine validation. To fill this research gap, the aim of the present dissertation was to examine the role of source credibility in routine validation processes of text information. This dissertation argues that both source credibility and plausibility are considered in these processes. In particular, information plausibility is proposed as the primary criterion, but source credibility may modulate validation as an additional criterion. To this end, three studies with five self-paced reading experiments were conducted in which reading times served as an implicit indicator of validation and plausibility judgments as an explicit indicator, and the convergence or divergence between the two indicators was interpreted. The first study examined the interplay of plausibility and source credibility for the validation of world-knowledge consistent versus inconsistent text information embedded in short narratives. This highly plausible or highly implausible information was provided by a high- or low-expertise source. In Study 1, plausibility dominated validation as suggested by faster reading times and higher plausibility judgments for world-knowledge consistent information. Importantly, source credibility modulated the validation of highly implausible information but seemed to not matter for plausible information. High-credible sources increased the implausibility of highly implausible information to a greater extent compared with low-credible sources as indicated by longer reading times and lower plausibility judgments. These results diverged from recent findings from Foy et al. (2017). The second study investigated whether the modulating role of source credibility depends on the degree of implausibility of an information. Thus, Study 2 extended Study 1 by an intermediate, somewhat implausible level of plausibility (comparable to the implausible claims in Foy et al., 2017). Similar to Study 1, plausibility dominated validation as indicated by lower reading times and plausibility judgments with higher world-knowledge inconsistency. Again, source credibility had no effect on the routine validation of plausible information. However, high-credible sources mitigated the implausibility of somewhat implausible information as indicated by faster reading times and higher plausibility judgments but exacerbated the implausibility of highly implausible information as indicated by slower reading times and lower plausibility judgments. In short, Study 2 findings not only integrates the seemingly divergent results of Study 1 and Foy et al. (2017) but also provides strong support for the assumption that the degree of implausibility determines the modulating role of source credibility for validation. The third study examined the relationship of source credibility and plausibility in an ecologically valid social media setting with short Twitter messages varying in world-knowledge and text-belief consistency by trustworthy and untrustworthy sources. In sum, plausibility and to a lesser extent source credibility mattered for routine validation and explicit evaluation of text information as indicated by reading times and plausibility judgments. However, the pattern partly diverged from Study 1 and 2, possibly because the source information was more salient. In sum, the present dissertation yielded three insights. First, the findings further extends evidence for routine validation based on world-knowledge and prior beliefs. Second, the studies suggest that source credibility can modulate validation. Readers used source credibility cues for routine validation and the explicit evaluation of text information in all studies. Third, the impact of source credibility seems to depend on the degree of implausibility of information. The present findings have theoretical implications for theories of validation and text comprehension as well as practical implications for targeting threats associated with the prevalence of inaccurate information, for example, on the World Wide Web. Future research using eye-tracking methodology could further disentangle the routine and strategic underlying processes of the relationship between source credibility and plausibility. N2 - Zahlreiche empirische Untersuchungen konnten zeigen, dass ein passiver und evaluativer Prozess – genannt Validierung – die Aktivierung und Integration von Textinformationen mit leserseitigem Vorwissen und Überzeugungen als grundlegende Prozesse des Textverstehens begleitet. Während der Konstruktion des Situationsmodells erfassen Validierungsprozesse fortlaufend und implizit die Plausibilität einer eingehenden Information, indem sie die Konsistenz mit leserseitigem Vorwissen und Überzeugungen sowie mit Kontextinformationen (z. B. vorherige Textinformationen) überprüfen. Die Erforschung weiterer Einflussgrößen für die Validierung hat jedoch gerade erst begonnen. Ein Forschungszweig beschäftigt sich mit der Frage, wie sich Kontextinformationen und Vorwissen in ihrem Beitrag zu Integrations- und Validierungsprozessen unterscheiden. Ein Befund dabei ist, dass das Vorwissen häufig einen stärkeren Einfluss auf die Validierungsprozesse hat und folglich die Informationsplausibilität das primäre Kriterium für die Validierung von Textinformationen ist. Starke Kontextinformationen können jedoch ebenfalls für die Bewertung von eingehenden Informationen herangezogen werden. Eine spezifische Kontextinformation, die eine konzeptuelle Verbindung zu der Validität einer Information hat und daher eine besondere Relevanz für die Validierung von Textinformationen besitzt, ist die Glaubwürdigkeit der Quelle, die eine Textinformation liefert. Es gibt jedoch nur vereinzelte Studien, die das interaktive Zusammenspiel der Informationsplausibilität und Quellenglaubwürdigkeit für die Validierung von Textinformationen untersucht haben. Die vorliegende Dissertation setzt an dieser Lücke an und untersucht die Rolle der Quellenglaubwürdigkeit für die routinierte Validierung von Textinformationen. Dabei wird angenommen, dass sowohl die Plausibilität als auch die Quellenglaubwürdigkeit in diesen Prozessen berücksichtigt werden. Die Plausibilität einer Information sollte hierbei das primäre Kriterium sein, das zur Validierung herangezogen wird, aber die Quellenglaubwürdigkeit sollte als zusätzliches Kriterium genutzt werden und die Prozesse potentiell zu modulieren. Zur Überprüfung dieser Annahmen wurden drei Lesezeitstudien mit insgesamt fünf Experimenten durchgeführt. Ob implizite und explizite Maße konvergieren oder divergieren ist aufschlussreich für die Untersuchung der Prozesse des Textverstehens. Daher dienten die Lesezeit als implizites Maß für Validierungsprozesse und die Beurteilung der Plausibilität einer Textinformation als explizites Maß in allen Studien. Die erste Studie untersuchte die Beziehung von Plausibilität und Quellenglaubwürdigkeit bei der Validierung von Textinformationen, die konsistent (plausibel) oder inkonsistent (stark unplausibel) mit dem Vorwissen waren. Diese Textinformationen waren eingebettet in kurzen Geschichten und wurden von einer Quelle mit viel bzw. wenig Expertise hinsichtlich des angesprochenen Wissensbereichs geäußert. In Studie 1 führten plausible Textinformationen zu kürzeren Lesezeiten und höheren Plausibilitätsurteilen als stark unplausible Textinformationen. Für plausible Informationen schien die Quellenglaubwürdigkeit keine Rolle zu spielen, jedoch führten glaubwürdige Quellen zu höheren Lesezeiten und niedrigeren Plausibilitätsurteilen bei stark unplausiblen Informationen. Studie 1 legt nahe, dass die Konsistenz mit dem Vorwissen das Hauptkriterium für die Validierung war und die Quellenglaubwürdigkeit als zusätzliches Kriterium die Validierung unplausibler Informationen modulieren kann, jedoch in der Wirkrichtung scheinbar abweichend zu aktuellen Befunden ist (Foy et al., 2017). Die zweite Studie untersuchte, ob die in Studie 1 gefundene, modulierende Rolle der Quellenglaubwürdigkeit für Validierungsprozesse vom Grad der Unplausibilität einer Information abhängt. Hierzu wurden die Konzeption und die Materialien der ersten Studie um eine mittlere Plausibilitätsstufe, die als „etwas unplausibel“ bezeichnet werden kann, erweitert; sonst waren die Studien sehr ähnlich. In Studie 2 zeigte sich ein dreigestufter Plausibilitätseffekt abhängig von der Konsistenz mit dem Vorwissen. Plausible Textinformationen wurden schneller gelesen und als plausibler beurteilt als etwas unplausible Informationen. Diese wiederum wurden schneller gelesen und als plausibler eingeschätzt als stark unplausible Informationen. Erneut wurde die Quellenglaubwürdigkeit während des Lesens plausibler Informationen nicht berücksichtigt, modulierte aber die Validierung unplausibler Informationen. Glaubwürdige Quellen verglichen mit unglaubwürdigen Quellen führten zu kürzeren Lesezeiten und einer höher eingeschätzten Plausibilität für etwas unplausible Informationen, aber verlängerten die Lesezeiten und verringerten die Plausibilitätsurteile stark unplausibler Informationen – letzteres war identisch mit dem Ergebnis von Studie 1. Studie 2 zeigt, dass die Plausibilität einer Information das Hauptkriterium für wissensbasierte Validierungsprozesse war. Wenn Informationen einen gewissen Grad an Unplausibilität erreichen, können glaubwürdige Quellen die Plausibilität eigentlich unplausibler Informationen erhöhen oder sogar weiter verringern. Die Ergebnisse von Studie 2 belegen die Annahme, dass der Grad der Unplausibilität einer Information die modulierende Rolle der Glaubwürdigkeit einer Quelle bestimmt und darüber hinaus werden die Befunde von Studie 1 und Foy et al. (2017) integriert. Die dritte Studie untersuchte die Beziehung von Plausibilität und Quellenglaubwürdigkeit eingebettet in einem sozialen Medium mit kurzen Twitter-Nachrichten als ein ökologisch valider Kontext. Die Nachrichten unterschieden sich in der vom Text vermittelten Überzeugung und der Vorwissenskonsistenz. Diese Nachrichten wurden präsentiert von stark und wenig vertrauenswürdigen Quellen. Zusammenfassend zeigen Lesezeiten und Plausibilitätsurteile, dass die Informationsplausibilität und in einem geringeren Maße die Quellenglaubwürdigkeit für die routinierte Validierung und explizite Bewertung der Textinformationen von Bedeutung waren, aber mit einem teilweise abweichenden Muster zu Studie 1 und 2. Eine mögliche Erklärung könnte in den stark salienten Quelleninformationen in Studie 3 liegen. Zusammengefasst hat die vorliegende Dissertation drei Erkenntnisse erbracht. Erstens, die Befundlage für routinierte Validierungsprozesse basierend auf der Plausibilität einer Information wurde erweitert. Zweitens, die Studien legen nahe, dass die Glaubwürdigkeit einer Quelle dabei auch eine Rolle spielt: in allen Studien nutzten die Leserinnen und Leser die Quellenglaubwürdigkeit als zusätzlichen Hinweis zur Validierung und zur expliziten Plausibilitätsbewertung von Textinformationen. Drittens, die Stärke und die Richtung des Einflusses der Quellenglaubwürdigkeit für die wissensbasierte Validierung von Textinformationen scheint vom Grad der Unplausibilität einer Information abzuhängen. Diese Ergebnisse erlauben Schlussfolgerungen für Theorien der Validierung und des Textverstehens sowie praktische Implikationen für die Bekämpfung von möglichen Folgen, die mit der Verbreitung von Falschinformationen verbunden sind. Zukünftige Experimente basierend auf Blickbewegungen könnten helfen die routinierten und strategischen Prozesse genauer zu trennen, die die Beziehung von Quellenglaubwürdigkeit und Plausibilität für die Validierung bestimmen.

How the relationship between body movements and controlled object movements influences the sense of agency and the sense of ownership T1 - Ich kontrolliere es, aber ist es deshalb ein Teil von mir? Wie die Umsetzung von Körperbewegungen in Bewegungen von kontrollierten Objekten Sense of agency und Sense of ownership beeinflusst N2 - The “active self” approach suggests that any object we manipulate voluntarily and foreseeably becomes part of our “self” in the sense that we feel control over this object (sense of agency) and experience it as belonging to our own body (sense of ownership). While there is considerable evidence that we can indeed experience both a sense of agency and a sense of ownership over a broad variety of objects when we control these through our actions, the approach has also been criticized for exaggerating the flexibility of the human self. In this thesis, I investigate the influence that the relationship between the body movements controlling an object and the movements of the object itself has on the process of integrating an object into the self. I demonstrate that fully controlling an object is not sufficient for it to be integrated into the self since both explicit and implicit measures of the sense of agency and the sense of ownership indicate less or no integration when body movements are transformed into inverted object movements. Furthermore, I show that such inversions lead to the downregulation of sensory signals either from the body or from the controlled object in order to deal with the conflicting multisensory information when performing such actions. I argue that this downregulation is the underlying factor behind the diminished or eliminated integration of inverted body and object movements and I discuss further pathways for possible future studies building up on these findings. N2 - Der “Active Self”-Ansatz sagt aus, dass jedes Objekt, welches wir willentlich und vorhersehbar manipulieren, Teil unseres „Selbst“ wird in dem Sinne, dass wir Kontrolle über dieses Objekt empfinden (Sense of agency) und es als zu unserem eigenen Körper zugehörig erleben (Sense of ownership). Während es eine beträchtliche Menge an Evidenz dafür gibt, dass wir tatsächlich sowohl Sense of agency als auch Sense of ownership für eine breite Vielfalt an Objekten empfinden können, wenn wir diese durch unsere Handlungen kontrollieren, wurde der Ansatz auch dafür kritisiert die Flexibilität des menschlichen Selbst über zu strapazieren. In dieser Arbeit untersuche ich den Einfluss, den die Beziehung zwischen den Körperbewegungen, welche ein Objekt kontrollieren, und den Bewegungen des Objekts selbst auf den Integrationsprozess eines Objekts in das Selbst hat. Ich demonstriere, dass ein Objekt vollständig zu kontrollieren nicht ausreichend ist, damit es in das Selbst integriert wird, da sowohl explizite als auch implizite Maße für Sense of agency und Sense of ownership weniger oder keine Integration zeigen, wenn Körperbewegungen in invertierte Objektbewegungen transformiert werden. Darüber hinaus zeige ich, dass solche Invertierungen zur Herunterregulierung sensorischer Signale entweder vom Körper oder vom kontrollierten Objekt führen, um mit der konfligierenden multisensorischen Information umzugehen, wenn solche Handlungen ausgeführt werden. Ich argumentiere, dass diese Herunterregulierung der zugrundeliegende Faktor ist für die verringerte oder eliminierte Integration invertierter Körper- und Objektbewegungen und ich diskutiere weitere Richtungen für mögliche zukünftige Studien, die auf diesen Befunden aufbauen.

T1 - Is Applied Ethics Morally Problematic? JF - Journal of Academic Ethics N2 - This paper argues that applied ethics can itself be morally problematic. As illustrated by the case of Peter Singer’s criticism of social practice, morally loaded communication by applied ethicists can lead to protests, backlashes, and aggression. By reviewing the psychological literature on self-image, collective identity, and motivated reasoning three categories of morally problematic consequences of ethical criticism by applied ethicists are identified: serious psychological discomfort, moral backfiring, and hostile conflict. The most worrisome is moral backfiring: psychological research suggests that ethical criticism of people’s central moral convictions can reinforce exactly those attitudes. Therefore, applied ethicists unintentionally can contribute to a consolidation of precisely those social circumstances that they condemn to be unethical. Furthermore, I argue that the normative concerns raised in this paper are not dependent on the commitment to one specific paradigm in moral philosophy. Utilitarianism, Aristotelian virtue ethics, and Rawlsian contractarianism all provide sound reasons to take morally problematic consequences of ethical criticism seriously. Only the case of deontological ethics is less clear-cut. Finally, I point out that the issues raised in this paper provide an excellent opportunity for further interdisciplinary collaboration between applied ethics and social sciences. I also propose strategies for communicating ethics effectively.

Methology One hundred two cancer patients who completed an 8-week yoga therapy were randomly allocated to two groups: reminder (N = 51) vs. no-reminder group (N = 51). After completing yoga therapy, the reminder group received weekly e-mails for 24 weeks, which reminded them of practicing yoga, whereas the no-reminder group did not. Primary outcomes were fatigue and practice frequency, and long-term outcomes were fatigue, depression, and quality of life. Data were assessed using questionnaires after yoga therapy (T1) and 6 months after completing yoga therapy (T2). Result A significantly stronger reduction of general (p = 0.038, d = 0.42) and emotional fatigue (p = 0.004, d = 0.59) and a higher increase of practice frequency (p = 0.015, d = 0.52) between T1 and T2 were found for the reminder group compared to the no-reminder group. In the mediation model, practice frequency as a mediator partially explained the changes in emotional fatigue (indirect effect B =  - 0.10). Long-term effects of yoga therapy regarding fatigue, depression, and quality of life were found (F > 7.46, p < 0.001, d > 0.54). Conclusion Weekly reminder e-mails after yoga therapy can positively affect general and emotional fatigue and help cancer patients with fatigue establish a regular yoga practice at home. However, higher practice frequency did not lead to higher physical or cognitive fatigue improvement, suggesting other factors that mediate efficacy on physical or cognitive fatigue, such as mindfulness or side effects of therapy.

Despite these findings, it is not clear if it is the lack of restriction that leads to the improvement. Our goal was to explore the effects of motor restrictions on divergent thinking for different movement states. In addition, we assessed whether spontaneous eye blinks, which are linked to motor execution, also predict performance. In experiment 1, we compared the performance in Guilford's alternate uses task (AUT) during walking vs. sitting, and analysed eye blink rates during both conditions. We found that AUT scores were higher during walking than sitting. Albeit eye blinks differed significantly between movement conditions (walking vs. sitting) and task phase (baseline vs. thinking vs. responding), they did not correlate with task performance. In experiment 2 and 3, participants either walked freely or in a restricted path, or sat freely or fixated on a screen. When the factor restriction was explicitly modulated, the effect of walking was reduced, while restriction showed a significant influence on the fluency scores. Importantly, we found a significant correlation between the rate of eye blinks and creativity scores between subjects, depending on the restriction condition. Our study shows a movement state-independent effect of restriction on divergent thinking. In other words, similar to unrestrained walking, unrestrained sitting also improves divergent thinking. Importantly, we discuss a mechanistic explanation of the effect of restriction on divergent thinking based on the increased size of the focus of attention and the consequent bias towards flexibility.

Previous studies demonstrated that physicians who behave empathic in their interaction with patients have a positive effect on health outcomes. In this study, we investigated if the mere perception of physicians as empathic/not empathic modulates pain despite an emotionally neutral interaction with the patients. Methods N = 60 women took part in an experimental study that simulated a clinical interaction. In the paradigm, each participant watched two immersive 360° videos via a head-mounted display from a patient’s perspective. The physicians in the videos behaved either empathic or not empathic towards a third person. Importantly, these physicians remained emotionally neutral in the subsequent virtual interaction with the participants. Finally, participants received a controlled, painful pressure stimulus within the narratives of the videos. Results The physicians in the high compared with the low empathy videos were rated as more empathic and more likable, indicating successful experimental manipulation. In spite of later neutral behaviour of physicians, this short observation of physicians’ behaviour towards a third person was sufficient to modulate pain tolerance of the participants. Conclusions The finding of this study that the mere observation of physicians’ behaviour towards a third person modulates pain, despite a neutral direct interaction with the participants, has important clinical implications. Further, the proposed paradigm enables investigating aspects of patient–physician communication that are difficult to examine in a clinical setting.

Traditionally, novel theories and approaches are tested utilizing animal models. One way to study inherent anxiety in rodents is the elevated plus-maze (EPM). The EPM is a plus-shaped platform with two closed, i.e., walled, arms and two open unwalled arms. If given the opportunity to freely explore the apparatus, rodents instinctively avoid the open arms to protect themselves from predators. Hence, they spent less time on open and more time on closed arms, which is behaviorally associated with general anxiety. In the course of the pharmacological validation, it was found that this exploratory pattern can be reversed by anxiolytic substances, e.g., benzodiazepines, or potentiated by anxiogenics. One of the significant advantages of the EPM is that no prior training session is required in contrast to conditioning studies, thus allowing to observe natural behavior. Therefore, together with the economic and uncomplicated setup, the EPM has become a standard preclinical rodent anxiety test over the decades. In order to validate these rodent anxiety tests, there have recently been attempts to retranslate them to humans. A paramount of cross-species validation is not only the simple transferability of these animal tests but also the observation of anxiety behaviors that are evolutionarily conserved across species. Accordingly, it could be possible to conclude various factors associated with the etiology and maintenance of anxiety disorders in humans. So far, convincing translations of the EPM to humans are still lacking. For that reason, the primary aim of this dissertation is to retranslate the EPM throughout three studies and to evaluate cross-species validity critically. Secondly, the undertaken studies are set out to observe ambulatory activity equivalent to rodent EPM behavior, i.e., open arm avoidance. Thirdly, the undertaken studies aimed to assess the extent to which trait anxiety influences human exploratory activity on the platform to associate it with the assumption that rodent EPM-behavior is a reflection of general anxiety. Finally, virtual reality (VR) was the method of choice to maintain the economic advantage and adjust the EPM size to humans. Study 1 (N = 30) was set up to directly transfer the rodent EPM regarding test design and experimental procedure using a Computer Automatic Virtual Environment (CAVE). The results revealed that humans unlike rodents display a general open arms approach during free exploration. However, open arm avoidance was associated with high trait anxiety and acrophobia (fear of height), which was initially assessed as a control variable due to the virtual platform height. Regression analyses and subjective anxiety ratings hinted at a more significant influence of acrophobia on open arm avoidance. In addition, it was assumed that the open arms approach might have resulted from claustrophobic tendencies experienced in the closed arms due to the high walls. Study 2 (N = 61) sought to differentiate the influence of trait anxiety and acrophobia and adapt the virtual EPM to humans. Therefore, parts of the platform held a semi-transparent grid-floor texture, and the wall height on the closed arms was reduced to standard handrail level. Moreover, participants were priorly screened to exclude clinically significant levels of acrophobia, claustrophobia, and agoraphobia. The data on general exploratory activity showed no arm preference. Regression analyses confirmed that acrophobia is related to open arm avoidance, corroborating the finding of Study 1. Surprisingly, for trait anxiety, the result of Study 1 could not be replicated. Instead, for trait anxiety, no significant effect was found indicating that predominantly fear of heights shapes human EPM behavior even on a subclinical stage. In Study 3 (N = 57), the EPM was embedded into a city setting to 1) create a more natural human environment and 2) eliminate height. Furthermore, a head-mounted display was utilized for VR presentation, and arousal ratings were introduced. Participants were screened for high and low levels of trait anxiety and agoraphobia, and claustrophobia. Replicating the findings of Study 2, no difference in open and closed arm activity was observed, and no effect was found in relationship with trait anxiety. The data on anxiety ratings and claustrophobia suggest a positive correlation indicating that in this city EPM, claustrophobic tendencies might play a role in closed arm avoidance. In summary, this thesis added valuable insights into the retranslation of a well-established standard anxiety test used in rodents. However, it also majorly challenges current findings on the cross-species validity of the EPM. Various explanatory models for the results are critically discussed and associated with clinical implications concerning future research. N2 - Die Angstforschung ist eines der wichtigsten psychologischen Forschungsgebiete und blickt auf eine jahrzehntelange Forschungstätigkeit zurück. Traditionell werden neue Theorien und Ansätze anhand von Tiermodellen getestet. Eine Möglichkeit, inhärente Angst bei Nagetieren zu untersuchen, ist das Elevated Plus-Maze (EPM). Das EPM ist eine plusförmige Plattform mit zwei geschlossenen, d. h. mit Wänden versehenen, Armen und zwei offenen, nicht mit Wänden umschlossenen, Armen. Wenn Nagetiere die Möglichkeit haben, die Plattform frei zu erkunden, meiden sie instinktiv die offenen Arme, um sich vor Fressfeinden zu schützen, d.h. sie verbringen weniger Zeit in den offenen und mehr Zeit in den geschlossenen Armen, was verhaltensmäßig mit Ängstlichkeit assoziiert wird. Im Rahmen der pharmakologischen Validierung wurde festgestellt, dass dieses Explorationsmuster durch anxiolytische Substanzen, z. B. Benzodiazepine, umgekehrt oder durch anxiogene Substanzen verstärkt werden kann. Einer der wesentlichen Vorteile des EPM ist, dass im Gegensatz zu Konditionierungsstudien kein vorheriges Training erforderlich ist und somit natürliches Verhalten beobachtet werden kann. Zusammen mit dem ökonomischen und unkomplizierten Versuchsaufbau hat sich das EPM daher im Laufe der Jahrzehnte zu einem Standardtest für präklinische Angstforschung bei Nagern entwickelt. Um diese Angsttests von Nagern zu validieren, wurde kürzlich versucht, diese auf den Menschen zu übertragen. Eine wichtige Voraussetzung für die artenübergreifende Validierung ist nicht nur die einfache Translation dieser Tiertests, sondern auch die Beobachtung von Angstverhalten, das evolutionär über alle Arten hinweg konserviert ist. Darauf aufbauend könnte es möglich sein, auf verschiedene Faktoren zu schließen, die mit der Entstehung und Aufrechterhaltung von Angststörungen beim Menschen in Verbindung stehen. Bislang fehlt es noch an einer überzeugenden Übertragung des EPM auf den Menschen. Aus diesem Grund besteht das primäre Ziel dieser Dissertation darin, das EPM in drei Studien neu zu übersetzen und die speziesübergreifende Validität kritisch zu bewerten. Zweitens sollen die durchgeführten Studien eine dem EPM-Verhalten von Nagetieren äquivalente Bewegungsaktivität beobachten, d.h. die Vermeidung offener Arme. Drittens zielten die durchgeführten Studien darauf ab, das Ausmaß zu bewerten, in dem Angstmerkmale das Explorationsverhalten des Menschen auf der Plattform beeinflussen, um sie mit der Annahme in Verbindung zu bringen, dass das EPM-Verhalten von Nagetieren Ängstlichkeit repräsentiert. Schließlich war die virtuelle Realität (VR) die Methode der Wahl, um die ökonomische Validität zu erhalten und das EPM in seiner Größe an den Menschen anpassen zu können. In Studie 1 (N = 30) wurde das Tier-EPM hinsichtlich des Testdesigns und des Versuchsablaufs unter Verwendung einer computergesteuerten virtuellen Umgebung (CAVE) direkt auf den Menschen übertragen. Die Ergebnisse zeigten, dass Menschen im Gegensatz zu Nagern während der freien Exploration generell eine Annäherung zu den offenen Armen zeigen. Die Vermeidung offener Arme war jedoch mit hoher Traitängstlichkeit und Akrophobie (Höhenangst) verbunden, die aufgrund der Höhe der virtuellen Plattform zunächst als Kontrollvariable erhoben wurde. Regressionsanalysen und subjektive Angstbewertungen deuteten auf einen stärkeren Einfluss der Akrophobie auf die Vermeidung der offenen Arme hin. Darüber hinaus wurde angenommen, dass die Vermeidung der offenen Arme aus klaustrophobischen Tendenzen resultieren könnte, die in den geschlossenen Armen aufgrund der hohen Wände auftreten. In Studie 2 (N = 61) wurde versucht, den Einfluss von Traitängstlichkeit und Akrophobie zu differenzieren und das virtuelle EPM an den Menschen anzupassen. Daher waren Teile der Plattform mit einer halbtransparenten Gitterbodenstruktur versehen, und die Wandhöhe in den geschlossenen Armen wurde auf die Höhe eines Standardgeländers reduziert. Darüber hinaus wurden die Versuchsteilnehmer vorselektiert um klinisch signifikante Werte von Akrophobie, Klaustrophobie und Agoraphobie auszuschließen. Die Daten zu generellem Explorationsverhalten zeigten, dass keine Armpräferenz besteht. Die durchgeführte Regressionsanalyse demonstrierte, dass die Vermeidung der offenen Arme mit Akrophobie zusammenhängt, was die Ergebnisse von Studie 1 bestätigt. Überraschenderweise konnte das Ergebnis von Studie 1 in Bezug auf Traitängstlichkeit nicht repliziert werden. Stattdessen wurde für Ängstlichkeit kein signifikanter Effekt gefunden, was darauf hindeutet, dass hauptsächlich Höhenangst das menschliche EPM-Verhalten sogar in einem subklinischen Stadium prägt. In Studie 3 (N = 57) wurde das EPM in eine städtische Umgebung eingebettet, um 1) eine für den Menschen natürlichere Umgebung zu schaffen und 2) den Faktor Höhe zu eliminieren. Darüber hinaus wurde für die VR-Präsentation eine Virtual-Reality-Brille verwendet, und Arousalratings eingeführt. Die Teilnehmer wurden auf hohe und niedrige Werte von Traitängstlichkeit und Agoraphobie sowie Klaustrophobie untersucht. Wie in Studie 2 konnte kein Unterschied zwischen der Explorationstendenzen der offenen und der geschlossenen Arme beobachtet werden, und es wurde kein Effekt in Bezug auf die erhobenen Angstmerkmale festgestellt. Die Daten zu Angstbewertungen und Klaustrophobie deuten auf eine positive Korrelation hin, was darauf bedeutet, dass bei diesem Stadt-EPM klaustrophobische Tendenzen eine Rolle bei der Vermeidung des geschlossenen Arms spielen könnten. Zusammenfassend lässt sich sagen, dass diese Arbeit wertvolle Einblicke in die Retranslation eines gut etablierten Standard-Angsttests für Nager liefert. Sie stellt jedoch auch die derzeitigen Erkenntnisse über die artenübergreifende Validität des EPM in Frage. Verschiedene Erklärungsmodelle für die Ergebnisse werden kritisch diskutiert und mit klinischen Implikationen für die zukünftige Forschung verbunden.

Several methods have been proposed to quantify the post-error slowing effect, and we discuss two main methods: The traditional method of comparing response times in correct post-error trials to response times of correct trials that follow another correct trial, and a more recent proposal of comparing response times in correct post-error trials to the corresponding correct pre-error trials. Based on thorough re-analyses of two datasets, we argue that the latter method provides an inflated estimate by also capturing the (partially) independent effect of pre-error speeding. We propose two solutions for improving the assessment of human error processing, both of which highlight the importance of distinguishing between initial pre-error speeding and later post-error slowing.

In present study, we varied the arm and finger postures in the context of a virtual reaching and grasping task and tested whether this manipulation can simultaneously affect the perceived size and distance of external objects. Participants manually controlled visual cursors, aiming at reaching and enclosing a distant target object, and judged the size and distance of this object. We observed that a visual-proprioceptive discrepancy introduced during the reaching part of the action simultaneously affected the judgments of target distance and of target size (Experiment 1). A related variation applied to the grasping part of the action affected the judgments of size, but not of distance of the target (Experiment 2). These results indicate that perceptual effects observed in the context of actions can directly arise through sensory integration of multimodal redundant signals and indirectly through perceptual constancy mechanisms.

The sudden direct-gaze effect refers to the processing advantage for targets appearing on peripheral faces that suddenly establish eye contact. Here, we investigate the necessity of social information for attention capture by (sudden onset) ostensive cues. Six experiments involving 204 participants applied (1) naturalistic faces, (2) arrows, (3) schematic eyes, (4) naturalistic eyes, or schematic facial configurations (5) without or (6) with head turn to an attention-capture paradigm. Trials started with two stimuli oriented towards the observer and two stimuli pointing into the periphery. Simultaneous to target presentation, one direct stimulus changed to averted and one averted stimulus changed to direct, yielding a 2 × 2 factorial design with direction and motion cues being absent or present. We replicated the (sudden) direct-gaze effect for photographic faces, but found no corresponding effects in Experiments 2-6. Hence, a holistic and socially meaningful facial context seems vital for attention capture by direct gaze. STATEMENT OF SIGNIFICANCE: The present study highlights the significance of context information for social attention. Our findings demonstrate that the direct-gaze effect, that is, the prioritization of direct gaze over averted gaze, critically relies on the presentation of a meaningful holistic and naturalistic facial context. This pattern of results is evidence in favor of early effects of surrounding social information on attention capture by direct gaze.

A1 - Kirsch, Wladimir A1 - Kunde, Wilfried A1 - Pfister, Roland T1 - Temporal binding as multisensory integration: Manipulating perceptual certainty of actions and their effects JF - Attention, Perception & Psychophysics N2 - It has been proposed that statistical integration of multisensory cues may be a suitable framework to explain temporal binding, that is, the finding that causally related events such as an action and its effect are perceived to be shifted towards each other in time. A multisensory approach to temporal binding construes actions and effects as individual sensory signals, which are each perceived with a specific temporal precision. When they are integrated into one multimodal event, like an action-effect chain, the extent to which they affect this event's perception depends on their relative reliability. We test whether this assumption holds true in a temporal binding task by manipulating certainty of actions and effects. Two experiments suggest that a relatively uncertain sensory signal in such action-effect sequences is shifted more towards its counterpart than a relatively certain one. This was especially pronounced for temporal binding of the action towards its effect but could also be shown for effect binding. Other conceptual approaches to temporal binding cannot easily explain these results, and the study therefore adds to the growing body of evidence endorsing a multisensory approach to temporal binding.

Participants saw a target object while performing finger movements. Then either the size of the target or the size of the adopted finger postures was judged. The target judgment was attracted by the adopted finger posture indicating sensory integration of body-related and visual signals. The magnitude of integration, however, depended on how the task was initially described. It was substantially larger when the experimental instructions indicated that finger movements and the target object relate to the same event than when they suggested that they are unrelated. This outcome highlights the role of causal inference processes in the emergence of action specific influences in perception.

In Experiment 1, participants tried to hit a circular target with a stylus movement under restricted feedback conditions. We measured the perception of target size during action planning and observed larger estimates for larger movement distances. In Experiment 2, we then tested the hypothesis that this action specific influence on perception is due to changes in the allocation of spatial attention. For this purpose, we replaced the hitting task by conditions of focused and distributed attention and measured the perception of the former target stimulus. The results revealed changes in the perceived stimulus size very similar to those observed in Experiment 1. These results indicate that action's effects on perception root in changes of spatial attention.

In this study, an experiment was conducted to investigate whether these levels of representation would be affected by adding illustrations to narrative text and whether the order of text and illustrations would make a difference. Students aged between 7 and 13 years (N = 146) read 12 narrative texts, 4 of them with illustrations presented before their corresponding sentences, 4 with illustrations presented after, and 4 without any illustration. A sentence recognition task was used to assess the accuracy for text surface, textbase, and situation model. For the text surface and situation model, neither the presence of illustrations nor the order of text and illustrations influenced accuracy. However, the textbase was negatively affected by illustrations when they followed their corresponding sentences. We suggest that illustrations can initiate model inspection after situation model construction (Schnotz, 2014), a process that can make substantial changes to the textbase representation.

JF - Motivation and Emotion N2 - Catastrophizing thoughts may contribute to the development of anxiety, but functional emotion regulation may help to improve treatment. No study so far directly compared up- and down-regulation of fear by cognitive reappraisal. Here, healthy individuals took part in a cued fear experiment, in which multiple pictures of faces were paired twice with an unpleasant scream or presented as safety stimuli. Participants (N = 47) were asked (within-subjects) to down-regulate, to up-regulate and to maintain their natural emotional response. Valence and arousal ratings indicated successful up- and down-regulation of the emotional experience, while heart rate and pupil dilation increased during up-regulation, but showed no reduction in down-regulation. State and trait anxiety correlated with evaluations of safety but not threat stimuli, which supports the role of deficient safety learning in anxiety. Reappraisal did not modulate this effect. In conclusion, this study reveals evidence for up-regulation effects in fear, which might be even more efficient than down-regulation on a physiological level and highlights the importance of catastrophizing thoughts for the maintenance of fear and anxiety.

K. A1 - Pittig, Andre T1 - A dimensional measure of safety behavior: A non-dichotomous assessment of costly avoidance in human fear conditioning JF - Psychological Research N2 - Safety behavior prevents the occurrence of threat, thus it is typically considered adaptive. However, safety behavior in anxiety-related disorders is often costly, and persists even the situation does not entail realistic threat. Individuals can engage in safety behavior to varying extents, however, these behaviors are typically measured dichotomously (i.e., to execute or not). To better understand the nuances of safety behavior, this study developed a dimensional measure of safety behavior that had a negative linear relationship with the admission of an aversive outcome. In two experiments, a Reward group receiving fixed or individually calibrated incentives competing with safety behavior showed reduced safety behavior than a Control group receiving no incentives. This allowed extinction learning to a previously learnt warning signal in the Reward group (i.e., updating the belief that this stimulus no longer signals threat). Despite the Reward group exhibited extinction learning, both groups showed a similar increase in fear to the warning signal once safety behavior was no longer available. This null group difference was due to some participants in the Reward group not incentivized enough to disengage from safety behavior. Dimensional assessment revealed a dissociation between low fear but substantial safety behavior to a safety signal in the Control group. This suggests that low-cost safety behavior does not accurately reflect the fear-driven processes, but also other non-fear-driven processes, such as cost (i.e., engage in safety behavior merely because it bears little to no cost). Pinpointing both processes is important for furthering the understanding of safety behavior.

Yet, in human agents, efferent activities produce perceptual changes in various sensory modalities and in various temporal and spatial proximities. Some of these changes occur at the “biological” body, and they are to some extent conveyed by “private” sensory signals, whereas other changes occur in the environment of that biological body and are conveyed by “public” sensory signals. We discuss commonalties and differences of these signals for generating selfhood. We argue that despite considerable functional overlap of these sensory signals in generating self-experience, there are reasons to tell them apart in theorizing and empirical research about development of the self.

However, during experimental investigations of cognitive processes, movements are often highly restricted which is rather unnatural. In order to improve our understanding of natural behavior, this thesis investigates the interaction between cognition and movements by focusing on spontaneous blinks, which naturally interact with other body movements. Spontaneous blinks are inevitably connected to vision as they shut out incoming visual information. Both sensory-based and cognitive factors, for example, stimulus occurrence and evaluation, were reported to influence blink behavior. Our first study investigated if such influences are comparable for visual and non-visual input. The chosen experimental design allowed dissociating sensory-driven and cognitive influences, which then could be compared between the visual and auditory domain. Our results show that blinks are more strongly modulated during passive observation of visual input compared to auditory input. This modulation is however enhanced for both input modalities by an increased attentional demand. In addition, the cognitively defined meaning of a stimulus changes blink latency independent of the sensory domain. Overall, our findings show that spontaneous blinks and cognitive processes are linked beyond vision. Moreover, the underlying cognitive processes that influence blinks are largely the same across different sensory input indicating that blinks are profoundly integrated into our system. When investigating natural behavior, it is important to consider that movements rarely occur in isolation, but are executed side by side. As these movements interact and have a link to cognitive processes, the complexity of our system increases. In order to take this complexity into account, the second part of the experimental research focused on movement interactions, more specifically on the interactions between blinks, pupil size and speaking. Our results reveal that speech-related motor activity increases blink rate and pupil size as well as modulates blink timing. This is in line with previous research that described a relation between different body and eye movements. Importantly, each bodily-induced change in eye movements affects visual information intake. Therefore, different movements can be tightly linked to perceptual processes through complex interactions. Altogether, the work of this thesis provides rich evidence that movements and cognitive processes are deeply intertwined. Therefore, movements should be seen as an integral part of our system. Taking the relevance of movements and their interactions into account during experimental investigations is necessary in order to reveal a more realistic and complete picture of human natural behavior. N2 - Während unseres natürlichen Verhaltens werden kognitive Prozesse und Körperbewegungen wie Kopf- oder Augenbewegungen oder Lidschläge parallel ausgeführt. Allerdings werden Bewegungen in experimentellen Untersuchungen zu kognitiven Prozessen meist stark eingeschränkt, was unnatürlich ist. Um natürliches Verhalten besser zu verstehen, wird in dieser Dissertation die Interaktion zwischen Kognition und Bewegung untersucht. Der Fokus liegt auf spontanen Lidschlägen, die auch mit anderen Körperbewegungen auf natürliche Weise interagieren. Das Blinzeln ist unweigerlich mit dem Sehen verbunden, da bei jedem Lidschluss die Informationsaufnahme unterbrochen wird. Frühere Forschungsergebnisse zeigten, dass sowohl sensorische als auch kognitive Faktoren, wie beispielsweise Reizpräsentation und -evaluation, das Blinzeln beeinflussen können. Die erste Studie dieser Dissertation untersuchte, ob dieselben Einflüsse auf das Blinzeln wirken, wenn auch nicht-visuelle Informationen präsentiert werden. Das gewählte Versuchsdesign erlaubte rein sensorische von kognitiven Einflüssen auf das Blinzeln zu trennen. Diese Einflüsse konnten wiederum zwischen visuellem und auditivem Input verglichen werden. Unsere Ergebnisse zeigen, dass das Blinzeln stärker bei visuellem als bei auditivem Input angepasst wird, wenn dieser nur passiv verfolgt wird. Sobald allerdings Aufmerksamkeit auf den Input gerichtet wird, wird diese Anpassung an den sensorischen Input in beiden Modalitäten auf ähnliche Weise verstärkt. Zusätzlich wird der Zeitpunkt des Blinzelns durch die kognitive Bewertung der Reize verzögert - unabhängig davon, ob ein Reiz visuell oder auditiv präsentiert wird. Insgesamt legen unsere Experimente dar, dass das spontane Blinzeln und kognitive Prozesse über das Sehen hinaus miteinander verknüpft sind. Die zu Grunde liegenden kognitiven Prozesse, die das Blinzeln beeinflussen, sind sogar weitgehend dieselben bei unterschiedlichem sensorischen Input. Das Blinzeln scheint demnach tiefgreifend in unser System integriert zu sein. Ein weiterer wichtiger Aspekt natürlichen Verhaltens ist die gleichzeitige Ausübung mehrerer Bewegungen. Da diese Bewegungen miteinander interagieren und eine Verbindung zu kognitiven Prozessen besteht, erhöht sich die Komplexität unseres Systems. Im zweiten Teil der experimentellen Untersuchungen wurden daher Bewegungsinteraktionen in den Vordergrund gestellt. Die präsentierten Studien haben insbesondere den Einfluss verschiedener Bewegungsaspekte des Sprechens auf unser spontanes Blinzeln bzw. auf die Pupillengröße untersucht. Unsere Ergebnisse zeigen, dass sprechbezogene Bewegungen sowohl die Anzahl der Lidschlüsse als auch die Pupillengröße erhöhen, sowie den Zeitpunkt der Lidschlüsse beeinflussen. Auch andere Forscher fanden solche Zusammenhänge zwischen verschiedenen Körper- und Augenbewegungen. Da jede vom Körper verursachte Veränderung der Augenbewegung zudem unsere visuelle Reizaufnahme verändert, kann man schlussfolgern, dass verschiedene Bewegungen und deren komplexe Interaktionen eng mit unserer Wahrnehmung verbunden sind. Alles in allem liefert diese Arbeit weitreichende Beweise, wie stark Bewegungen und kognitive Prozesse miteinander verwoben sind. Daher sollten Bewegungen als wesentlicher Teil unseres Systems angesehen werden. Wir müssen daher die Bedeutung von Bewegungen und deren Interaktionen in experimentelle Forschung einbeziehen, um ein realistischeres und kompletteres Bild unseres natürlichen Verhaltens zu enthüllen.

A1 - Pauli, Paul T1 - Social cognitive factors outweigh negative emotionality in predicting COVID-19 related safety behaviors JF - Preventive Medicine Reports N2 - Emotion-motivation models propose that behaviors, including health behaviors, should be predicted by the same variables that also predict negative affect since emotional reactions should induce a motivation to avoid threatening situations. In contrast, social cognitive models propose that safety behaviors are predicted by a different set of variables that mainly reflect cognitive and socio-structural aspects. Here, we directly tested these opposing hypotheses in young adults (N = 4134) in the context of COVID-19-related safety behaviors to prevent infections. In each participant, we collected measures of negative affect as well as cognitive and socio-structural variables during the lockdown in the first infection wave in Germany. We found a negative effect of the pandemic on emotional responses. However, this was not the main predictor for young adults’ willingness to comply with COVID-19-related safety measures. Instead, individual differences in compliance were mainly predicted by cognitive and socio-structural variables. These results were confirmed in an independent data set. This study shows that individuals scoring high on negative affect during the pandemic are not necessarily more likely to comply with safety regulations. Instead, political measures should focus on cognitive interventions and the societal relevance of the health issue. These findings provide important insights into the basis of health-related concerns and feelings as well as behavioral adaptations.

T1 - Self-reported mask-related worrying reduces relative avoidance bias toward unmasked faces in individuals with low Covid19 anxiety syndrome JF - Cognitive Research: Principles and Implications N2 - Facial masks have become and may remain ubiquitous. Though important for preventing infection, they may also serve as a reminder of the risks of disease. Thus, they may either act as cues for threat, priming avoidance-related behavior, or as cues for a safe interaction, priming social approach. To distinguish between these possibilities, we assessed implicit and explicit evaluations of masked individuals as well as avoidance bias toward relatively unsafe interactions with unmasked individuals in an approach-avoidance task in an online study. We further assessed Covid19 anxiety and specific attitudes toward mask-wearing, including mask effectiveness and desirability, hindrance of communication from masks, aesthetic appeal of masks, and mask-related worrying. Across one sample of younger (18–35 years, N = 147) and one of older adults (60+ years, N = 150), we found neither an average approach nor avoidance bias toward mask-wearing compared to unmasked individuals in the indirect behavior measurement task. However, across the combined sample, self-reported mask-related worrying correlated with reduced avoidance tendencies toward unmasked individuals when Covid19 anxiety was low, but not when it was high. This relationship was specific to avoidance tendencies and was not observed in respect to explicit or implicit preference for mask-wearing individuals. We conclude that unsafe interaction styles may be reduced by targeting mask-related worrying with public interventions, in particular for populations that otherwise have low generalized Covid19 anxiety.

A1 - Haendel, Barbara F. T1 - Delusional thinking and action binding in healthy individuals JF - Scientific Reports N2 - Action binding is the effect that the perceived time of an action is shifted towards the action related feedback. A much larger action binding effect in schizophrenia compared to normal controls has been shown, which might be due to positive symptoms like delusions. Here we investigated the relationship between delusional thinking and action binding in healthy individuals, predicting a positive correlation between them. The action binding effect was evaluated by comparing the perceived time of a keypress between an operant (keypress triggering a sound) and a baseline condition (keypress alone), with a novel testing method that massively improved the precision of the subjective timing measurement. A positive correlation was found between the tendency of delusional thinking (measured by the 21-item Peters et al. delusions inventory) and action binding across participants after controlling for the effect of testing order between operant and baseline conditions. The results indicate that delusional thinking in particular influences action time perception and support the notion of a continuous distribution of schizotypal traits with normal controls at one end and clinical patients at the other end.

Although the trait chronic regulatory focus has been linked to impulse buying, no evidence yet exists for an effect of situational regulatory focus and no research has examined whether the fit of chronic and situational regulatory focus can influence impulse buying with actual consumptive consequences rather than purchase intentions. Two laboratory experiments (total N = 250) manipulated situational regulatory focus before providing opportunities for impulse buying. In addition, cognitive constraint was manipulated as a potential boundary condition for regulatory focus effects. Situational promotion focus increased impulse buying relative to situational prevention focus in participants with strong chronic promotion, consistent with regulatory fit theory and independently of cognitive constraint. Surprisingly, situational promotion focus also increased impulse buying in participants with strong chronic prevention, but only under low cognitive constraint. These results may be explained by diverging mediating cognitive processes for promotion vs. prevention focus' effect on impulse buying. Future research must focus more on combining relevant states and traits in predicting consumer behavior. Marketing implications are discussed.

Possible causes for underachievement are low motivational dispositions (need for cognition) and metacognitive competences. This study tested the interplay of these variables longitudinally with gifted and non-gifted students from Germany (N = 341, 137 females) in Grades 6 (M = 12.02 years at t1) and 8 (M = 14.07 years). Declarative and procedural metacognitive competences were assessed in the domain of reading comprehension. Path analyses showed incremental effects of procedural metacognition over and above intelligence on the development of school achievement in gifted students (β = .139). Moreover, declarative metacognition and need for cognition interactively predicted procedural metacognition (β = .169), which mediated their effect on school achievement.

We investigated how word and sentence reading skills relate to reading comprehension differentially across the first 6 years of schooling and tested which reading variable best predicted teacher judgements. We conducted our research in a rather transparent language, namely, German, drawing on two different data sets. The first was derived from the normative sample of a reading comprehension test (ELFE-II), including 2056 first to sixth graders with readings tests at the word, sentence and text level. The second sample included 114 students from second to fourth grade. The latter completed a series of tests that measured word and sentence reading fluency, pseudoword reading, AWM, reading comprehension, self-concept and teacher ratings. We analysed the data via hierarchical regression analyses to predict reading comprehension and teacher judgements. The impact of reading fluency was strongest in second and third grade, afterwards superseded by sentence comprehension. AWM significantly contributed to reading comprehension independently of reading fluency, whereas basic decoding skills disappeared after considering fluency. Students' AWM and reading comprehension predicted teacher judgements on reading fluency. Reading comprehension judgements depended both on the students' self-concept and reading comprehension. Our results underline that the role of word reading accuracy for reading comprehension quickly diminishes during elementary school and that teachers base their assessments mainly on the current reading comprehension skill.

T1 - Associative learning shapes visual discrimination in a web-based classical conditioning task JF - Scientific Reports N2 - Threat detection plays a vital role in adapting behavior to changing environments. A fundamental function to improve threat detection is learning to differentiate between stimuli predicting danger and safety. Accordingly, aversive learning should lead to enhanced sensory discrimination of danger and safety cues. However, studies investigating the psychophysics of visual and auditory perception after aversive learning show divergent findings, and both enhanced and impaired discrimination after aversive learning have been reported. Therefore, the aim of this web-based study is to examine the impact of aversive learning on a continuous measure of visual discrimination. To this end, 205 participants underwent a differential fear conditioning paradigm before and after completing a visual discrimination task using differently oriented grating stimuli. Participants saw either unpleasant or neutral pictures as unconditioned stimuli (US). Results demonstrated sharpened visual discrimination for the US-associated stimulus (CS+), but not for the unpaired conditioned stimuli (CS-). Importantly, this finding was irrespective of the US's valence. These findings suggest that associative learning results in increased stimulus salience, which facilitates perceptual discrimination in order to prioritize attentional deployment.

To investigate the affective consequences of opponent suffering on a revenge seeking individual, two experiments (total N = 82) recorded facial muscle activity while participants observed the reaction of a provoking opponent to a (retaliatory) sound punishment in a laboratory aggression task. Opponents reacted via prerecorded videos either with facial displays of pain, sadness, or neutrality. Results indicate that participants enjoyed seeing the provocateur suffer: indexed by a coordinated muscle response featuring an increase in zygomaticus major (and orbicularis oculi muscle) activation accompanied by a decrease in corrugator supercilii activation. This positive facial reaction was only shown while a provoking opponent expressed pain. Expressions of sadness, and administration of sound blasts to nonprovoking opponents, did not modulate facial activity. Overall, the results suggest that revenge-seeking individuals enjoy observing the offender suffer, which could represent schadenfreude or satisfaction of having succeeded in the retaliation goal.

A1 - Pauli, Paul T1 - Thigmotaxis in a virtual human open field test JF - Scientific Reports N2 - Animal models are used to study neurobiological mechanisms in mental disorders. Although there has been significant progress in the understanding of neurobiological underpinnings of threat-related behaviors and anxiety, little progress was made with regard to new or improved treatments for mental disorders. A possible reason for this lack of success is the unknown predictive and cross-species translational validity of animal models used in preclinical studies. Re-translational approaches, therefore, seek to establish cross-species translational validity by identifying behavioral operations shared across species. To this end, we implemented a human open field test in virtual reality and measured behavioral indices derived from animal studies in three experiments (N=31, N=30, and N=80). In addition, we investigated the associations between anxious traits and such behaviors. Results indicated a strong similarity in behavior across species, i.e., participants in our study-like rodents in animal studies-preferred to stay in the outer region of the open field, as indexed by multiple behavioral parameters. However, correlational analyses did not clearly indicate that these behaviors were a function of anxious traits of participants. We conclude that the realized virtual open field test is able to elicit thigmotaxis and thus demonstrates cross-species validity of this aspect of the test. Modulatory effects of anxiety on human open field behavior should be examined further by incorporating possible threats in the virtual scenario and/or by examining participants with higher anxiety levels or anxiety disorder patients.

One prominent mechanism of automatic attentional control is the Orienting Response (OR). Despite the fundamental significance of the OR in everyday life, only little is known about how the OR is affected by healthy aging. We tested this question in two age groups (19–38 and 55–72 years) and measured skin-conductance responses (SCRs) and event-related brain potentials (ERPs) to novels (i.e., short environmental sounds presented only once in the experiment; 10% of the trials) compared to standard sounds (600 Hz sinusoidal tones with 200 ms duration; 90% of the trials). Novel and standard stimuli were presented in four conditions differing in the inter-stimulus interval (ISI) with a mean ISI of either 10, 3, 1, or 0.5 s (blocked presentation). In both age groups, pronounced SCRs were elicited by novels in the 10 s ISI condition, suggesting the elicitation of stable ORs. These effects were accompanied by pronounced N1 and frontal P3 amplitudes in the ERP, suggesting that automatic novelty processing and orientation of attention are effective in both age groups. Furthermore, the SCR and ERP effects declined with decreasing ISI length. In addition, differences between the two groups were observable with the fastest presentation rates (i.e., 1 and 0.5 s ISI length). The most prominent difference was a shift of the peak of the frontal positivity from around 300 to 200 ms in the 19–38 years group while in the 55–72 years group the amplitude of the frontal P3 decreased linearly with decreasing ISI length. Taken together, this pattern of results does not suggest a general decline in processing efficacy with healthy aging. At least with very rare changes (here, the novels in the 10 s ISI condition) the OR is as effective in healthy older adults as in younger adults. With faster presentation rates, however, the efficacy of the OR decreases. This seems to result in a switch from novelty to deviant processing in younger adults, but less so in the group of older adults.

On the Importance of Ecological Validity and Virtual Reality for Social Attention Research T1 - Praktischerweise Valide? Über die Bedeutung von ökologischer Validität und virtueller Realität in der sozialen Aufmerksamkeitsforschung N2 - Gazes are of central relevance for people. They are crucial for navigating the world and communicating with others. Nevertheless, research in recent years shows that many findings from experimental research on gaze behavior cannot be transferred from the laboratory to everyday behavior. For example, the frequency with which conspecifics are looked at is considerably higher in experimental contexts than what can be observed in daily behavior. In short: findings from laboratories cannot be generalized into general statements. This thesis is dedicated to this matter. The dissertation describes and documents the current state of research on social attention through a literature review, including a meta-analysis on the /gaze cueing/ paradigm and an empirical study on the robustness of gaze following behavior. In addition, virtual reality was used in one of the first studies in this research field. Virtual reality has the potential to significantly improve the transferability of experimental laboratory studies to everyday behavior. This is because the technology enables a high degree of experimental control in naturalistic research designs. As such, it has the potential to transform empirical research in the same way that the introduction of computers to psychological research did some 50 years ago. The general literature review on social attention is extended to the classic /gaze cueing/ paradigm through a systematic review of publications and a meta-analytic evaluation (Study 1). The cumulative evidence supported the findings of primary studies: Covert spatial attention is directed by faces. However, the experimental factors included do not explain the surprisingly large variance in the published results. Thus, there seem to be further, not well-understood variables influencing these social processes. Moreover, classic /gaze cueing/ studies have limited ecological validity. This is discussed as a central reason for the lack of generalisability. Ecological validity describes the correspondence between experimental factors and realistic situations. A stimulus or an experimental design can have high and low ecological validity on different dimensions and have different influences on behavior. Empirical research on gaze following behavior showed that the /gaze cueing/ effect also occurs with contextually embedded stimuli (Study 2). The contextual integration of the directional cue contrasted classical /gaze cueing/ studies, which usually show heads in isolation. The research results can thus be transferred /within/ laboratory studies to higher ecologically valid research paradigms. However, research shows that the lack of ecological validity in experimental designs significantly limits the transferability of experimental findings to complex situations /outside/ the laboratory. This seems to be particularly the case when social interactions and norms are investigated. However, ecological validity is also often limited in these studies for other factors, such as contextual embedding /of participants/, free exploration behavior (and, thus, attentional control), or multimodality. In a first study, such high ecological validity was achieved for these factors with virtual reality, which could not be achieved in the laboratory so far (Study 3). Notably, the observed fixation patterns showed differences even under /most similar/ conditions in the laboratory and natural environments. Interestingly, these were similar to findings also derived from comparisons of eye movement in the laboratory and field investigations. These findings, which previously came from hardly comparable groups, were thus confirmed by the present Study 3 (which did not have this limitation). Overall, /virtual reality/ is a new technical approach to contemporary social attention research that pushes the boundaries of previous experimental research. The traditional trade-off between ecological validity and experimental control thus becomes obsolete, and laboratory studies can closely inherit an excellent approximation of reality. Finally, the present work describes and discusses the possibilities of this technology and its practical implementation. Within this context, the extent to which this development can still guarantee a constructive classification of different laboratory tests in the future is examined. N2 - Blicke sind für Menschen von zentraler Relevanz. Sie sind entscheidend für die Navigation in der Welt und für die Kommunikation mit Mitmenschen. Dennoch zeigt die Forschung der letzten Jahre, dass sich Erkenntnisse aus der experimentellen Forschung zu Blickverhalten vom Labor nicht in alltägliches Verhalten übertragen lassen. So ist beispielsweise die Häufigkeit, mit der Mitmenschen angeschaut werden, erheblich höher in experimentellen Kontexten als das beobachtbare alltägliche Verhalten. Kurz: Erkenntnisse aus Laboren lassen sich nicht zu allgemeinen Aussagen generalisieren. Diesem Spannungsfeld ist die hier vorliegende Arbeit gewidmet. Diese Doktorarbeit beschreibt und dokumentiert den aktuellen Forschungsstand zur sozialen Aufmerksamkeit anhand einer Literaturübersicht inklusive einer Metaanalyse zum /gaze cueing/ Paradigma sowie einer empirischen Untersuchung zur Robustheit des Blickfolgeverhaltens. Zudem wird in einer der ersten Studien in diesem Forschungsfeld virtuelle Realität eingesetzt. Virtuelle Realität hat das Potenzial, die Übertragbarkeit zwischen experimentellen Laboruntersuchungen auf alltägliches Verhalten deutlich zu verbessern. Denn die Technologie ermöglicht eine hohe experimentelle Kontrolle in naturalistischen Forschungdesigns. Damit kann sie die empirische Forschung ebenso stark verändern wie die Einführung des Computers für psychologische Forschung vor rund 50 Jahren. Die Literaturübersicht über soziale Aufmerksamkeit wurde durch eine systematische Begutachtung der Publikationen und einer meta-analystische Auswertung zum klassischen /gaze cueing/ Paradigma erweitert (Studie 1). Die kumulierte Evidenz unterstützt die Befunde primärer Studien: Verdeckte räumliche Aufmerksamkeit wird durch Gesichter gelenkt. Allerdings zeigte sich eine überraschend große Varianz in den publizierten Ergebnissen, die durch die untersuchten experimentellen Faktoren nicht erklärt werden konnte. Es scheint also noch Weitere, nicht gut verstandene Einflussgrößen auf diesen sozial-kognitiven Prozess zugeben. Klassische /gaze cueing/ Studien besitzen zudem eine eingeschränkte ökologische Validität. Diese wird als ein zentraler Grund für die fehlende Generalisierbarkeit diskutiert. Ökologische Validität beschreibt die Übereinstimmung von experimentellen Faktoren mit realistischen Situationen. Ein Stimulus oder ein experimentelles Design kann auf verschiedenen Dimensionen hohe und niedrige ökologische Validität aufweisen. Dies kann auf verschiedene Verhaltensbereiche unterschiedlichen Einfluss haben. Die empirischen Untersuchungen zum Blickfolgeverhalten zeigten, dass der /gaze cueing/ Effekt auch bei kontextuell eingebundenen Stimuli auftritt (Studie 2). Die kontextuelle Einbindung des Richtungscues stellte dabei einen Kontrast zu klassichen /gaze cueing/ Studien dar, die in der Regel Köpfe in Isolation zeigen. Die Forschungsergebnisse lassen sich also /innerhalb/ von kontrollierten Laboruntersuchungen auch auf ökologisch validere Forschungsparadigmen übertragen. Forschungsarbeiten zeigen allerdings, dass die mangelnde ökologische Validität in experimentellen Designs die Übertragbarkeit von experimentellen Befunden auf komplexe Situationen /außerhalb/ des Labors erheblich einschränken. Dies scheint insbesondere der Fall zu sein, wenn soziale Interaktionen und Normen untersucht werden. Die ökologische Validität ist in diesen Studien aber auch für weitere Faktoren häufig eingeschränkt, wie beispielsweise die kontextuelle Einbettung /von Versuchspersonen/, freies Explorationsverhalten (und damit Aufmerksamkeitssteuerung) oder Multimodalität. In einer ersten Arbeit in diesem Forschungsfeld wurde für diese Faktoren mit virtueller Realität eine hohe ökologische Validität erreicht, die so bisher nicht im Labor zu erreichen war (Studie 3). Spannenderweise zeigten sich selbst unter /ähnlichsten/ Bedingungen im Labor und in der natürlichen Umgebung Unterschiede in den beobachteten Fixationsmustern. Interessanterweise sind diese ähnlich zu Befunden, die ebenfalls aus Vergleichen von Augenbewegung im Labor und Felduntersuchung stammten. Diese Befunde, die bisher auf wenig vergleichbare Untersuchungsgruppen beruhen, wurden durch die vorliegende Studie 3 (die diese Einschränkung nicht besitzt) bestätigt. Insgesamt steht der heutigen sozialen Aufmerksamkeitsforschung mit /virtueller Realität/ ein neuer technischer Ansatz zur Verfügung, der die Grenzen bisheriger experimenteller Forschung verschiebt. Die traditionelle Abwägung zwischen ökologische Validität und experimenteller Kontrolle wird damit hinfällig und in Laboruntersuchungen kann die Realität extrem nah nachgebildet werden.

Effects on symptom reduction and public health benefits should be examined across different anxiety disorders with comorbid conditions. Methods This multicenter randomized controlled trial compared two variants of prediction error-based exposure therapy (PeEx) in various anxiety disorders (both 12 sessions + 2 booster sessions, 100 min/session): temporally intensified exposure (PeEx-I) with exposure sessions condensed to 2 weeks (n = 358) and standard nonintensified exposure (PeEx-S) with weekly exposure sessions (n = 368). Primary outcomes were anxiety symptoms (pre, post, and 6-months follow-up). Secondary outcomes were global severity (across sessions), quality of life, disability days, and comorbid depression. Results Both treatments resulted in substantial improvements at post (PeEx-I: d\(_{within}\) = 1.50, PeEx-S: d\(_{within}\) = 1.78) and follow-up (PeEx-I: d\(_{within}\) = 2.34; PeEx-S: d\(_{within}\) = 2.03). Both groups showed formally equivalent symptom reduction at post and follow-up. However, time until response during treatment was 32% shorter in PeEx-I (median = 68 days) than PeEx-S (108 days; TR\(_{PeEx-I}\)-I = 0.68). Interestingly, drop-out rates were lower during intensified exposure. PeEx-I was also superior in reducing disability days and improving quality of life at follow-up without increasing relapse. Conclusions Both treatment variants focusing on the transdiagnostic exposure-based violation of threat beliefs were effective in reducing symptom severity and disability in severe anxiety disorders. Temporally intensified exposure resulted in faster treatment response with substantial public health benefits and lower drop-out during the exposure phase, without higher relapse. Clinicians can expect better or at least comparable outcomes when delivering exposure in a temporally intensified manner.

Therefore, it comes naturally, that different surface structures evoke different visual impressions in the viewer even if the material underlying these surface structures is the same. This topic is especially virulent for manufacturing processes in which more than one stakeholder is involved, but where the final product needs to meet certain criteria. A common practice to address such slight but perceivable differences in the visual appearance of structured surfaces is that trained evaluators assess the samples and assign a pass or fail. However, this process is both time consuming and cost intensive. Thus, we conducted two studies to analyze the relationship between physical surface structure parameters and participants visual assessment of the samples. With the first experiment, we aimed at uncovering a relationship between physical roughness parameters and visual lightness perception while the second experiment was designed to test participants' discrimination sensitivity across the range of stimuli. Perceived lightness and the measured surface roughness were nonlinearly related to the surface structure. Additionally, we found a linear relationship between the engraving parameter and physical brightness. Surface structure was an ideal predictor for perceived lightness and participants discriminated equally well across the entire range of surface structures.

To accomplish this goal, three approaches were adopted: First, an overview and systematic comparison of integrity tests was conducted with reference to the construction and application of the tests. Second, the nomological network of integrity tests was expanded with reference to honesty-humility and organizational citizenship behavior at their factor and facet level. Third, two promising methods to reduce faking on integrity tests were tested: the double rating method (Hui, 2001) and the indirect questioning technique. In line with previous research, the results of the overview and comparison of integrity measures confirmed that integrity tests are multidimensional and heterogenous. A clear definition of integrity is urgently needed. The personality trait of honesty-humility and its facets of fairness, and modesty revealed the most significant relationships to integrity. Moreover, organizational citizenship behavior and its facets of altruism, conscientiousness, and sportsmanship were found to significantly relate to integrity. Furthermore, integrity tests were able not only to predict organizational citizenship behavior but also to incrementally predict job performance and organizational citizenship behavior beyond the factor and facet level of the personality traits of conscientiousness and honesty-humility. In contrast to the indirect questioning technique, the double rating method, which includes an other rating and a self rating, was shown to be able to significantly reduce faking on integrity tests in an anonymous survey setting. This dissertation makes an important contribution to better explain the construct and nomological network of integrity, provide a more detailed view on integrity tests and their protection against faking, and expand the predictive and incremental validity of these tests. The implications for future research and practice are further discussed. N2 - Der Fokus dieser Dissertation liegt sowohl auf der Konstrukt- als auch auf der Kriteriumsvalidität von Integritätstests und deren Erhöhung mit Hilfe von drei Ansätzen: (a) Ein Überblick und systematischer Vergleich von Integritätstests mit Bezug auf deren Konstruktion und Anwendung wird erstellt. (b) Das nomologische Netzwerk von Integrität wird erweitert mit Bezug auf Honesty-Humility und freiwilligem Arbeitsverhalten sowohl auf Faktoren- als auch Facettenebene. (c) Zwei vielversprechende Ansätze, um Faking in Integritätstests zu reduzieren, werden getestet: die Doppelte Fragemethode (Hui, 2001) und indirektes Fragen. Im Ergebnis zeigte sich, dass die Multidimensionalität und Heterogenität von Integritätstests bestätigt wurde. Eine klare Definition von Integrität ist dringend notwendig. Mit Blick auf das nomologische Netzwerk zeigte Honesty-Humility und deren Facetten Fairness und Bescheidenheit die höchsten signifikanten Korrelationen mit Integrität. Beim freiwilligen Arbeitsverhalten und deren Facetten Altruismus, Gewissenhaftigkeit und Unkompliziertheit wurden ebenfalls signifikante Zusammenhänge gefunden. Des Weiteren zeigte sich, dass Integritätstests inkrementelle Validität besitzen über die Faktoren und Facetten von Gewissenhaftigkeit und Honesty-Humility hinaus bei der Vorhersage von beruflicher Leistung und bei der Vorhersage von freiwilligem Arbeitsverhalten. Im Hinblick auf die Reduzierung von Faking zeigte nur die Doppelte Fragemethode (d.h. Fremd- und Selbsteinschätzung der Items) in der anonymen Forschungssituation eine signifikante Reduzierung. Diese Dissertation leistet einen wichtigen Beitrag zum besseren Verständnis des Konstruktes und nomologischen Netzwerkes der Integrität, bietet einen detaillierten Einblick in Integritätstests sowie deren Schutz vor Faking und verbessert die prognostische und inkrementelle Validität von Integritätstests.

Their implications may vary across cultures in reference to predicting health-related quality of life (HRQoL). A convenience sample of N = 200 chronic heart failure (CHF) patients was recruited at cardiology centers in Germany (n = 100) and Pakistan (n = 100). Results indicated that trait-EI predicted better mental component of HRQoL in Pakistani and German CHF patients. Friends as social support appeared relevant for German patients only. Qualitative data indicate an internal locus of control in German as compared to Pakistani patients. Strengthening the beneficial role of social support in Pakistani patients is one example of how the current findings may inspire culture-specific treatment to empower patients dealing with the detrimental effects of CHF.

To examine whether such anxiety-modulated behaviors are conserved in humans, we re-translated this paradigm to a human setting using virtual reality in a Cave Automatic Virtual Environment (CAVE) system. In two studies, we examined whether the EPM exploration behavior of humans is modulated by their trait anxiety and also assessed the individuals’ levels of acrophobia (fear of height), claustrophobia (fear of confined spaces), sensation seeking, and the reported anxiety when on the maze. First, we constructed an exact virtual copy of the animal EPM adjusted to human proportions. In analogy to animal EPM studies, participants (N = 30) freely explored the EPM for 5 min. In the second study (N = 61), we redesigned the EPM to make it more human-adapted and to differentiate influences of trait anxiety and acrophobia by introducing various floor textures and lower walls of closed arms to the height of standard handrails. In the first experiment, hierarchical regression analyses of exploration behavior revealed the expected association between open arm avoidance and Trait Anxiety, an even stronger association with acrophobic fear. In the second study, results revealed that acrophobia was associated with avoidance of open arms with mesh-floor texture, whereas for trait anxiety, claustrophobia, and sensation seeking, no effect was detected. Also, subjects’ fear rating was moderated by all psychometrics but trait anxiety. In sum, both studies consistently indicate that humans show no general open arm avoidance analogous to rodents and that human EPM behavior is modulated strongest by acrophobic fear, whereas trait anxiety plays a subordinate role. Thus, we conclude that the criteria for cross-species validity are met insufficiently in this case. Despite the exploratory nature, our studies provide in-depth insights into human exploration behavior on the virtual EPM.

Virtual reality (VR)-based treadmill training can increase motivation and improve therapy outcomes. The present study evaluated an immersive virtual reality application (using a head-mounted display, HMD) for gait rehabilitation with patients to (1) demonstrate its feasibility and acceptance and to (2) compare its short-term effects to a semi-immersive presentation (using a monitor) and a conventional treadmill training without VR to assess the usability of both systems and estimate the effects on walking speed and motivation. Methods: In a within-subjects study design, 36 healthy participants and 14 persons with MS or stroke participated in each of the three experimental conditions (VR via HMD, VR via monitor, treadmill training without VR). Results: For both groups, the walking speed in the HMD condition was higher than in treadmill training without VR and in the monitor condition. Healthy participants reported a higher motivation after the HMD condition as compared with the other conditions. Importantly, no side effects in the sense of simulator sickness occurred and usability ratings were high. No increases in heart rate were observed following the VR conditions. Presence ratings were higher for the HMD condition compared with the monitor condition for both user groups. Most of the healthy study participants (89%) and patients (71%) preferred the HMD-based training among the three conditions and most patients could imagine using it more frequently. Conclusions For the first time, the present study evaluated the usability of an immersive VR system for gait rehabilitation in a direct comparison with a semi-immersive system and a conventional training without VR with healthy participants and patients. The study demonstrated the feasibility of combining a treadmill training with immersive VR. Due to its high usability and low side effects, it might be particularly suited for patients to improve training motivation and training outcome e. g. the walking speed compared with treadmill training using no or only semi-immersive VR. Immersive VR systems still require specific technical setup procedures. This should be taken into account for specific clinical use-cases during a cost-benefit assessment.

This was experimentally in-vestigated in rodents by examining the effect of a distal stress induction on threat conditioning, where stress impaired extinction learning and caused spontaneous recovery. However, this effect has never been experimentally investigated in humans, so far. Thus, the aim of this dissertation was to investigate the effect of distal stress on threat conditioning in humans. Therefore, two subsequent studies were conducted. For both studies, the threat conditioning paradigm comprised threat acquisition, extinction learning, and re-extinction. In the threat acquisition phase, two geometrical shapes were used as conditioned stimulus (CS), from which one (CS+) was paired with a painful electric stimulus (unconditioned stimulus, US), but not the other one (CS-). During extinction learning 24 h later and re-extinction seventeen days later, CSs were again presented but without any US delivery. In Study 1, 69 participants underwent either a stress (socially evaluated cold pressor test; SECPT) or sham protocol 10 days prior to threat conditioning. Furthermore, context effects were examined by placing the stress protocol in the same context (context-A stress, and sham group) or a different context (context-B stress group) than conditioning. Results revealed that the context-A, but not context-B, stress group displayed impaired safety learning (i.e. potenti-ation towards CS-) for startle response during threat acquisition. Moreover, the same stress group showed impaired threat extinction, evident in sustained CS discrimination in valence and arousal ratings during extinction learning, and memory recall. In sum, distal stress on the one hand impaired safety learning during threat conditioning on a level of startle response. On the other hand, stress impaired threat extinction on a level of ratings. Noteworthy, the effect of distal stress was only found when the stressor was placed in the same context as later threat learning. Hence, suggesting that the combination of stressor and stressor-associated context exerted the effect on threat extinction. In Study 2, it was examined if distal stress induction could also have an impact on threat and extinction processes without the necessity of context association. Therefore, the same stress (n = 45) or sham protocol (n = 44) as in Study 1 was conducted in a different context than and 24 h prior to a threat conditioning paradigm. Similar to Study 1, weakened extinction learning was found in fear ratings for the stress (vs. sham) group, which was indicated by persistent CS+/CS- differentiation after the first block of extinction trials. Alterations in safety learning towards the CS- during threat acquisition were only supported by significant correlations between stress measures on the stress day and conditioned startle response of the CS- during acquisition. Taken together, in two subsequent studies this dissertation provided first evidence of impaired threat extinction after distal stress induction in humans. Furthermore, impairments in safety learning, as can be observed in PTSD, were additionally demonstrated. Interestingly, the effects were boosted and more profound when associating the stressor to the later learning context. These results have clinical implications as they can be translated to the notion that prior stress exposure makes an individual more vulnerable for later aversive events. N2 - Stress stellt einen Hauptrisikofaktor für die Entstehung einer psychiatrischen Erkrankung, insbesondere PTSD und Angststörungen, dar. Dieser Prozess wird vermittelt über einen Wechsel des Gehirns in einen Zustand der Sensibilisierung, welcher das Individuum vulnerabler bei der Exposition eines weiteren aversiven Ereignisses macht. Experimentell ließ sich dies in Tierstudien durch Untersuchungen des Effektes von distalem Stress auf Threat-Konditionierung nachweisen. Die Ergebnisse der Studien weisen auf ein verschlechtertes Extinktionslernen und dessen Abruf aufgrund der Stressinduktion hin. Experimentelle Untersuchungen dieses Effektes beim Menschen fehlen jedoch bislang. Daher hat sich diese Dissertation das Ziel gesetzt, eben diesen Effekt von distalem Stress auf Threat-Konditionierung im Menschen zu untersuchen. Hierzu wurden zwei aufeinander aufbauende Studien durchgeführt. In beiden Studien wurden differenzielle Threat-Konditionierungsparadigmen verwendet, welche aus den Phasen der Threat-Akquisition, des Extinktionslernens und der Re-Extinktion bestanden. In der Threat-Akquisitionsphase wurden zwei geometrische Figuren als konditionierte Stimuli (CS) verwendet. Eine dieser Figuren (CS+) wurde mit einem leicht schmerzhaften elektrischen Stromreiz (unkonditionierter Stimulus, US) gekoppelt, wohingegen solch eine Paarung mit der anderen Figur (CS-) ausblieb. Während des Extinktionslernens und der Re-Extinktion, welche jeweils 24 h und 17 Tage nach der Akquisition stattfanden, wurden beide CSs ohne US-Paarung wiederholt präsentiert. In der ersten Studie durchliefen 69 Probanden entweder ein Stress- (Sozial-evaluativer Cold Pressor Test, SECPT) oder ein Sham-Kontrollprotokoll, welches zehn Tage vor dem Threat-Konditionierungsparadigma stattfand. Darüber hinaus wurden Kontexteffekte untersucht. Dieses wurde durch die Platzierung des Stressprotokolls, entweder im gleichen (Kontext-A Stress & Shamgruppe) oder in einem anderen Kontext (Kontext-B Stressgruppe) als das Lernparadigma, realisiert. Die Ergebnisse demonstrieren für die Kontext-A Stressgruppe im Gegensatz zur Kontext-B Stressgruppe während der Akquisitionsphase ein verschlechtertes Sicherheitslernen (d.h. eine Potenzierung der konditionierten Reaktionen des CS-) in der Startle-Reaktion. Darüber hinaus demonstrierte dieselbe Stressgruppe verschlechterte Extinktion, was sich in persistierender CS-Diskrimination in Valenz- und Arousalratings während des Extinktionslernens und des Gedächtnisabrufes äußerte. Zusammenfassend lässt sich sagen, dass distaler Stress einerseits das Sicherheitslernen während der Akquisitionsphase auf der Ebene der Startle-Reaktion verschlechterte. Andererseits verschlechterte Stress die Extinktion und verstärkte die Furchtrückkehr auf der Ebene der subjektiven Ratings. Allerdings ist wichtig zu erwähnen, dass diese Effekte des distalen Stresses nur gefunden wurden, wenn der Stressor im gleichen Kontext wie das Konditionierungsparadigma appliziert wurde. Dieses lässt vermuten, dass die Kombination aus Stressor und stressor-assoziiertem Kontext den verschlechternden Effekt auf die Extinktion ausübten. In der zweiten Studie wurde darauf aufbauend untersucht, ob distale Stressinduktion einen Einfluss auf Threat- und Extinktionsprozesse, auch ohne die Notwendigkeit der Kontextassoziation, haben kann. Hierfür wurden das gleiche Stress- (n = 45) und Sham-Kontrollprotokoll (n = 44) wie in Studie 1 durchlaufen. In diesem Fall jedoch in einem anderen Kontext und 24 h vor dem Konditionierungsparadigma. Vergleichbar mit Studie 1 konnte abgeschwächtes Extinktionslernen für die Stress- im Vergleich zur Shamgruppe festgestellt werden. Es zeigte sich nur für die Stressgruppe eine anhaltende CS+/CS- Differenzierung in den Furchtratings nach dem ersten Block des Extinktionslernens. Unterschiede im Sicherheitslernen bezüglich des CS- während der Akquisitionsphase ließen sich nicht finden. Jedoch deuten signifikante Korrelation zwischen Stressmaßen am Stresstag und der konditionierten Startle-Reaktion auf den CS- während der Akquisition auf einen Einfluss von Stress auf das Sicherheitslernen hin. Zusammengefasst liefern die Studien dieser Dissertation erste Evidenzen für verschlechterte Extinktionsprozesse nach distaler Stressinduktion beim Menschen. Darüber hinaus konnten Einbußen im Sicherheitslernen aufgrund des Stressors verzeichnet werden. Hervorzuheben ist, dass der Stresseffekt durch die Assoziation zwischen Stressor und Konditionierungskontext verstärkt wurde. Die Ergebnisse dieser Dissertation haben klinische Relevanz, da sie erste experimentelle Evidenzen am Menschen für die Annahme liefern, dass vorherige Stresserfahrungen ein Individuum vulnerabler für späteres aversives Lernen machen.

This suggests that what an agent counts as “body” is plastic, depending on what she or he controls. Yet there are possible limitations for such momentary plasticity. One of these limitations is that sensations stemming from the body (e.g., proprioception) and sensations stemming from objects outside the body (e.g., vision) are not integrated if they do not sufficiently “match”. What “matches” and what does not is conceivably determined by long–term experience with the perceptual changes that body movements typically produce. Children have accumulated less sensorimotor experience than adults have. Consequently, they express higher flexibility to integrate body-internal and body-external signals, independent of their “match” as suggested by rubber hand illusion studies. However, children’s motor performance in tool use is more affected by mismatching body-internal and body-external action effects than that of adults, possibly because of less developed means to overcome such mismatches. We review research on perception-action interactions, multisensory integration, and developmental psychology to build bridges between these research fields. By doing so, we account for the flexibility of the sense of body ownership for actively controlled events and its development through ontogeny. This gives us the opportunity to validate the suggested mechanisms for generating ownership by investigating their effects in still developing and incomplete stages in children. We suggest testable predictions for future studies investigating both body ownership and motor skills throughout the lifespan.

JF - Frontiers in Psychology N2 - Distributed learning is often recommended as a general learning strategy, but previous research has established its benefits mainly for learning with repeated materials. In two experiments, we investigated distributed learning with complementary text materials. 77 (Experiment 1) and 130 (Experiment 2) seventh graders read two texts, massed vs. distributed, by 1 week (Experiment 1) or 15 min (Experiment 2). Learning outcomes were measured immediately and 1 week later and metacognitive judgments of learning were assessed. In Experiment 1, distributed learning was perceived as more difficult than massed learning. In both experiments, massed learning led to better outcomes immediately after learning but learning outcomes were lower after 1 week. No such decrease occurred for distributed learning, yielding similar outcomes for massed and distributed learning after 1 week. In sum, no benefits of distributed learning vs. massed learning were found, but distributed learning might lower the decrease in learning outcomes over time.

Discrimination trainings are promising approaches for reducing such fear over-generalization. Here we investigated the efficacy of a fear-relevant vs. a fear-irrelevant discrimination training on fear generalization and whether the effects are increased with feedback during training. Eighty participants underwent two fear acquisition blocks, during which one face (conditioned stimulus, CS+), but not another face (CS−), was associated with a female scream (unconditioned stimulus, US). During two generalization blocks, both CSs plus four morphs (generalization stimuli, GS1–GS4) were presented. Between these generalization blocks, half of the participants underwent a fear-relevant discrimination training (discrimination between CS+ and the other faces) with or without feedback and the other half a fear-irrelevant discrimination training (discrimination between the width of lines) with or without feedback. US expectancy, arousal, valence ratings, and skin conductance responses (SCR) indicated successful fear acquisition. Importantly, fear-relevant vs. fear-irrelevant discrimination trainings and feedback vs. no feedback reduced generalization as reflected in US expectancy ratings independently from one another. No effects of training condition were found for arousal and valence ratings or SCR. In summary, this is a first indication that fear-relevant discrimination training and feedback can improve the discrimination between threat and safety signals in healthy individuals, at least for learning-related evaluations, but not evaluations of valence or (physiological) arousal.

B. T1 - EPOS: EEG Processing Open-Source Scripts JF - Frontiers in Neuroscience N2 - Background: Since the replication crisis, standardization has become even more important in psychological science and neuroscience. As a result, many methods are being reconsidered, and researchers’ degrees of freedom in these methods are being discussed as a potential source of inconsistencies across studies. New Method: With the aim of addressing these subjectivity issues, we have been working on a tutorial-like EEG (pre-)processing pipeline to achieve an automated method based on the semi-automated analysis proposed by Delorme and Makeig. Results: Two scripts are presented and explained step-by-step to perform basic, informed ERP and frequency-domain analyses, including data export to statistical programs and visual representations of the data. The open-source software EEGlab in MATLAB is used as the data handling platform, but scripts based on code provided by Mike Cohen (2014) are also included. Comparison with existing methods: This accompanying tutorial-like article explains and shows how the processing of our automated pipeline affects the data and addresses, especially beginners in EEG-analysis, as other (pre)-processing chains are mostly targeting rather informed users in specialized areas or only parts of a complete procedure. In this context, we compared our pipeline with a selection of existing approaches. Conclusion: The need for standardization and replication is evident, yet it is equally important to control the plausibility of the suggested solution by data exploration. Here, we provide the community with a tool to enhance the understanding and capability of EEG-analysis. We aim to contribute to comprehensive and reliable analyses for neuro-scientific research.

We investigated whether self-rated personality and inferences drawn from partners' faces influence economic decisions. Participants (N = 285) played the trust game in the role of the trustor as well as the ultimatum game in the role of the proposer and interacted with trustees and receivers represented by prototypical personality faces. Participants also evaluated both their own traits and the personality of the faces. In the trust game, trustees represented by faces rated higher on agreeableness yielded higher transferred amounts. This effect was more pronounced for trustors low on dispositional trust, whereas trustors high on dispositional trust did not relate their decisions to the faces. Trustees represented by faces rated higher on conscientiousness yielded higher transferred amounts only for trustors high on dispositional anxiety. In the ultimatum game, receivers represented by faces rated higher on conscientiousness yielded lower offers only for proposers high on dispositional assertiveness. These results extend previous findings on the inferences drawn from facial features and the influence of personality on decision making.

However, if they play an active role during internal perceptual switches is not known. We conducted two experiments involving an ambiguous plaid stimulus, wherein participants were asked to continuously report their percept, which could consist of either unidirectional coherent or bidirectional component movement. Our main results show that blinks and microsaccades did not facilitate perceptual switches. On the contrary, a reduction in eye movements preceded the perceptual switch. Blanks, on the other hand, thought to mimic the retinal consequences of a blink, consistently led to a switch. Through the timing of the blank-introduced perceptual change, we were able to estimate the delay between the internal switch and the response. This delay further allowed us to evaluate that the reduction in blink probability co-occurred with the internal perceptual switch. Additionally, our results indicate that distinct internal processes underlie the switch to coherent vs. component percept. Blanks exclusively facilitated a switch to the coherent percept, and only the switch to coherent percept was followed by an increase in blink rate. In a second study, we largely replicated the findings and included a microsaccade analysis. Microsaccades only showed a weak relation with perceptual switches, but their direction was correlated with the perceived motion direction. Nevertheless, our data suggests an interaction between microsaccades and blinks by showing that microsaccades were differently modulated around blinks compared with blanks. This study shows that a reduction in eye movements precedes internal perceptual switches indicating that the rate of blinks can set the stage for a reinterpretation of sensory input. While a perceptual switch based on changed sensory input usually leads to an increase in blink rate, such an increase was only present after the perceptual switch to coherent motion but absent after the switch to component percept. This provides evidence of different underlying mechanism or internal consequence of the two perceptual switches and suggests that blinks can uncover differences in internal percept-related processes that are not evident from the percept itself.

Contemporaneously, tVNS can be achieved by stimulating either the auricular branch or the cervical bundle of the vagus nerve, referred to as transcutaneous auricular vagus nerve stimulation(VNS) and transcutaneous cervical VNS, respectively. In order to advance the field in a systematic manner, studies using these technologies need to adequately report sufficient methodological detail to enable comparison of results between studies, replication of studies, as well as enhancing study participant safety. We systematically reviewed the existing tVNS literature to evaluate current reporting practices. Based on this review, and consensus among participating authors, we propose a set of minimal reporting items to guide future tVNS studies. The suggested items address specific technical aspects of the device and stimulation parameters. We also cover general recommendations including inclusion and exclusion criteria for participants, outcome parameters and the detailed reporting of side effects. Furthermore, we review strategies used to identify the optimal stimulation parameters for a given research setting and summarize ongoing developments in animal research with potential implications for the application of tVNS in humans. Finally, we discuss the potential of tVNS in future research as well as the associated challenges across several disciplines in research and clinical practice.

A1 - Gamer, Matthias T1 - Reflexive Gaze Shifts and Fear Recognition Deficits in Children with Callous-Unemotional Traits and Impulsivity/Conduct Problems JF - Brain Sciences N2 - The ability to efficiently recognize the emotions on others’ faces is something that most of us take for granted. Children with callous-unemotional (CU) traits and impulsivity/conduct problems (ICP), such as attention-deficit hyperactivity disorder, have been previously described as being “fear blind”. This is also associated with looking less at the eye regions of fearful faces, which are highly diagnostic. Previous attempts to intervene into emotion recognition strategies have not had lasting effects on participants’ fear recognition abilities. Here we present both (a) additional evidence that there is a two-part causal chain, from personality traits to face recognition strategies using the eyes, then from strategies to rates of recognizing fear in others; and (b) a pilot intervention that had persistent effects for weeks after the end of instruction. Further, the intervention led to more change in those with the highest CU traits. This both clarifies the specific mechanisms linking personality to emotion recognition and shows that the process is fundamentally malleable. It is possible that such training could promote empathy and reduce the rates of antisocial behavior in specific populations in the future.

CDH13 regulates axonal outgrowth and synapse formation, substantiating its relevance for neurodevelopmental processes. Several studies support the influence of CDH13 on personality traits, behavior, and executive functions. However, evidence for functional effects of common gene variation in the CDH13 gene in humans is sparse. Therefore, we tested for association of a functional intronic CDH13 SNP rs2199430 with ADHD in a sample of 998 adult patients and 884 healthy controls. The Big Five personality traits were assessed by the NEO-PI-R questionnaire. Assuming that altered neural correlates of working memory and cognitive response inhibition show genotype-dependent alterations, task performance and electroencephalographic event-related potentials were measured by n-back and continuous performance (Go/NoGo) tasks. The rs2199430 genotype was not associated with adult ADHD on the categorical diagnosis level. However, rs2199430 was significantly associated with agreeableness, with minor G allele homozygotes scoring lower than A allele carriers. Whereas task performance was not affected by genotype, a significant heterosis effect limited to the ADHD group was identified for the n-back task. Heterozygotes (AG) exhibited significantly higher N200 amplitudes during both the 1-back and 2-back condition in the central electrode position Cz. Consequently, the common genetic variation of CDH13 is associated with personality traits and impacts neural processing during working memory tasks. Thus, CDH13 might contribute to symptomatic core dysfunctions of social and cognitive impairment in ADHD.

We extended existing research by assuming that both, morning recovery (considered a resource) and anticipated leisure time (considered an anticipated resource gain), relate to work engagement. Anticipated leisure time comprises two constructs: general anticipation of leisure time, which refers to employees’ cognitive evaluation of their entire upcoming leisure time, and pleasant anticipation of a planned leisure activity, which describes a positive affective reaction because of one specific, upcoming leisure activity. We suggested that employees with high pleasant anticipation generate more thoughts of a planned leisure activity (ToPLA), which may distract them from their work, reducing their work engagement. A diary study over five days showed that morning recovery and general anticipation of leisure time were positively related to work engagement. Furthermore, employees with higher pleasant anticipation of a planned leisure activity reported more ToPLA. In contrast to our expectations, neither pleasant anticipation nor ToPLA was related to work engagement. In sum, this study introduced anticipated leisure time as a novel antecedent of work engagement and demonstrated that anticipated resource gains are important for high work engagement.

Here, we performed the largest ever analysis of brain left‐right asymmetry in ADHD, using 39 datasets of the ENIGMA consortium. Methods We analyzed asymmetry of subcortical and cerebral cortical structures in up to 1,933 people with ADHD and 1,829 unaffected controls. Asymmetry Indexes (AIs) were calculated per participant for each bilaterally paired measure, and linear mixed effects modeling was applied separately in children, adolescents, adults, and the total sample, to test exhaustively for potential associations of ADHD with structural brain asymmetries. Results There was no evidence for altered caudate nucleus asymmetry in ADHD, in contrast to prior literature. In children, there was less rightward asymmetry of the total hemispheric surface area compared to controls (t = 2.1, p = .04). Lower rightward asymmetry of medial orbitofrontal cortex surface area in ADHD (t = 2.7, p = .01) was similar to a recent finding for autism spectrum disorder. There were also some differences in cortical thickness asymmetry across age groups. In adults with ADHD, globus pallidus asymmetry was altered compared to those without ADHD. However, all effects were small (Cohen’s d from −0.18 to 0.18) and would not survive study‐wide correction for multiple testing. Conclusion Prior studies of altered structural brain asymmetry in ADHD were likely underpowered to detect the small effects reported here. Altered structural asymmetry is unlikely to provide a useful biomarker for ADHD, but may provide neurobiological insights into the trait.

In addition to curing cancer or prolonging life, increasing the quality of life is thus an important goal of oncology, which is why the burdens of cancer and treatment are becoming more important. A common side effect of cancer and its therapy is cancer-related fatigue, a tiredness that manifests itself on physical, emotional and cognitive levels and is not in proportion to previous physical efforts. Since the etiology of fatigue has not yet been fully clarified, symptom-oriented therapy is preferable to cause-specific therapy. In addition to activity management, sleep hygiene, and cognitive behavioral therapy, mind-body interventions such as yoga are recommended for reducing fatigue. Previous studies with small sample sizes were able to examine the efficacy of yoga regarding fatigue predominantly in patients with breast cancer. Long-term effects of yoga have rarely been studied and there have been no attempts to increase long-term effects through interventions such as reminder e-mails. This dissertation takes a closer look at these mentioned aspects of the study sample and long-term effects. An 8-week randomized controlled yoga intervention was conducted, including patients with different cancer types reporting mild to severe fatigue. Following the 8-week yoga therapy, a randomized group of participants received weekly reminder e-mails for 6 months for regular yoga practice, whereas the control group did not receive reminder e-mails. The first paper is a protocol article, which addresses the design and planned implementation of the research project this dissertation is based upon. This serves to ensure better replicability and comparability with other yoga studies. Due to a very low consent rate of patients in the pilot phase, it was necessary to deviate from the protocol article in the actual implementation and the planned inclusion criterion of fatigue >5 was reduced to fatigue >1. The second paper examines the efficacy of the eight-week yoga intervention. Patients in the intervention group who participated in the yoga classes seven times or more showed a significantly greater reduction in general and physical fatigue than those who participated less often. The efficacy of yoga was related to the number of attended yoga sessions. Women with breast cancer who participated in yoga reported greater reductions in fatigue than women with other cancer types. There was also an improvement for depression and quality of life after eight weeks of yoga therapy compared to no yoga therapy. These results imply that yoga is helpful in reducing depression and cancer-related fatigue, especially in terms of physical aspects and improving quality of life. The third paper focuses on the efficacy of reminder e-mails in terms of fatigue and practice frequency. Patients who received reminder e-mails reported greater reductions in general and emotional fatigue, as well as significant increases in practice frequency, compared to patients who did not receive reminder e-mails. Compared to fatigue scores before yoga, significantly lower fatigue and depression scores and higher quality of life were reported after yoga therapy and at follow-up six months later. Weekly e-mail reminders after yoga therapy may have positive effects on general and emotional fatigue and help cancer patients with fatigue establish a regular yoga practice at home. However, higher practice frequency did not lead to higher improvement in physical fatigue as found in Paper 2. This may indicate other factors that influence the efficacy of yoga practice on physical fatigue, such as mindfulness or side effects of therapy. This research project provides insight into the efficacy of yoga therapy for oncology patients with fatigue. It is important that such interventions be offered early, while fatigue symptoms are not too severe. Regular guided yoga practice can reduce physical fatigue, but subsequent yoga practice at home does not further reduce physical fatigue. Reminder emails after completed yoga therapy could only reduce patients' emotional fatigue. It may be that physical fatigue was reduced as much as possible by the previous yoga therapy and that there was a floor effect, or it may be that reminder emails are not suitable as an intervention to reduce physical fatigue at all. Further research is needed to examine the mechanisms of the different interventions in more detail and to find appropriate interventions that reduce all levels of fatigue equally. N2 - Die Anzahl der Krebs-Neuerkrankungen steigt stetig, während durch verbesserte Früherkennung und neue krebsspezifische Therapien die Sterberate sinkt. Neben der Heilung von Krebs oder Verlängerung der Lebenszeit ist somit eine Erhöhung der Lebensqualität wichtige Aufgabe der Onkologie, weshalb Nebenwirkungen der Krebsbehandlung näher betrachtet werden müssen. Eine häufige Folge von Krebserkrankungen und deren Therapie ist die krebsbedingte Fatigue, eine Müdigkeit, die sich auf physischer, emotionaler und kognitiver Ebene zeigt und nicht im Verhältnis zu vorhergehenden Anstrengungen steht. Da die Ätiologie der Fatigue bisher nicht vollständig geklärt ist, ist eine symptomorientierte Therapie der ursachenspezifischen Therapie vorzuziehen. Neben Aktivitätsmanagement, Schlafhygiene und kognitiver Umstrukturierung werden Mind-Body-Interventionen wie Yoga zur Reduktion von krebsbedingter Fatigue empfohlen. Bisherige Studien mit geringer Stichprobengröße konnten die Wirksamkeit von Yoga hinsichtlich Fatigue überwiegend bei Brustkrebspatientinnen überprüfen. Langfristige Effekte von Yoga wurden nur selten überprüft. Es gibt bisher keine Interventionen, wie beispielsweise Erinnerungs-E-Mails, die darauf zielen, derartige langfristige Effekte zu erhöhen. In dieser Dissertation werden auf die Aspekte Stichprobe und langfristige Effekte, näher eingegangen. Es wurde eine achtwöchige randomisierte, kontrollierte Yoga-Intervention durchgeführt, die in die Stichprobe alle PatientInnen mit onkologischen Erkrankungen einschloss, die leichte bis schwere Fatigue berichteten. Im Anschluss an die achtwöchige Yogatherapie erhielt eine randomisierte Gruppe der Teilnehmenden für sechs Monate wöchentliche Erinnerungs-E-Mails für die regelmäßige Yogapraxis, die die Kontrollgruppe nicht erhielt. Das erste Paper befasst sich als Protokollartikel genauer mit dem Aufbau und der geplanten Durchführung des gesamten Forschungsprojekts. Dies dient der Sicherung einer besseren Replizierbarkeit und Vergleichbarkeit mit anderen Yogastudien. Aufgrund einer sehr geringen Zustimmungsrate der PatientInnen in der Pilotphase musste vom Protokollartikel abgewichen werden und das geplante Einschlusskriterium der Fatigue >5 auf Fatigue >1 gesetzt werden. Das zweite Paper beschäftigt sich mit der Wirksamkeit der achtwöchigen Yoga-Intervention. PatientInnen in der Interventionsgruppe, die sieben Mal oder häufiger an der Yogaintervention teilgenommen haben, zeigten eine signifikant stärkere Reduktion der allgemeinen und physischen Fatigue als die PatientInnen der Kontrollgruppe. Die Wirksamkeit der Yoga-Intervention stand im Zusammenhang mit der Anzahl der teilgenommenen Yogastunden. Frauen mit Brustkrebs, die am Yoga teilnahmen, berichteten eine stärkere Reduktion der Fatigue als Frauen mit anderen Krebsarten. Auch für Depression und Lebensqualität konnte durch die achtwöchige Yogatherapie eine Verbesserung erzielt werden. Diese Ergebnisse implizieren, dass Yoga hilfreich ist, krebsbedingte Fatigue zu reduzieren, vor allem hinsichtlich physischer Aspekte. Das dritte Paper beschäftigt sich mit der Wirksamkeit von Erinnerungs-E-Mails hinsichtlich der Fatigue und Übungshäufigkeit. PatientInnen, die Erinnerungs-E-Mails erhielten, berichteten von einer stärkeren Reduktion der allgemeinen und emotionalen Fatigue, sowie einer signifikanten Erhöhung der Übungshäufigkeit. Im Vergleich zu den Werten vor der Yogatherapie wurden nach Yogatherapie und im Follow-Up sechs Monate später signifikant geringere Fatigue und Depressionswerte sowie eine höhere Lebensqualität berichtet. Wöchentliche Erinnerungs-E-Mails nach einer Yogatherapie können positive Effekte auf die allgemeine und emotionale Fatigue haben und KrebspatientInnen mit Fatigue helfen, eine regelmäßige Yogapraxis zu Hause zu etablieren. Eine höhere Übungshäufigkeit führte jedoch nicht zu einer höheren Verbesserung der physischen Fatigue, wie es in Paper 2 zu finden war. Dies kann auf andere Faktoren hindeuten, die die Wirksamkeit der Yogapraxis auf die physische Fatigue beeinflussen, wie Achtsamkeit oder Nebenwirkungen der Therapie. Dieses Forschungsprojekt gibt Aufschluss über die Wirksamkeit der Yogatherapie bei onkologischen PatientInnen mit Fatigue. Wichtig ist, dass derartige Interventionen früh angeboten werden, solange die Fatigue-Symptomatik nicht stark ausgeprägt ist. Regelmäßige geleitete Yogapraxis kann die physische Fatigue verringern, anschließend mehr Yogapraxis zu Hause reduzierte jedoch die physische Fatigue in diesem Forschungsprojekt nicht mehr weiter. Erinnerungs-E-Mails nach abgeschlossener Yogatherapie wirkten sich nur positiv auf die emotionale Fatigue der PatientInnen aus. Dies kann daran liegen, dass physische Fatigue durch die vorhergehende Yogatherapie bereits so stark wie möglich reduziert wurde und ein Boden-Effekt vorlag oder auch daran, dass die Erinnerungs-E-Mails als Intervention zur Reduktion von physischer Fatigue nicht ausreichend geeignet sind. Weitere Forschung ist notwendig, um die Mechanismen der verschiedenen Interventionen genauer zu überprüfen und geeignete Interventionen zu entwickeln, die alle Ebenen der Müdigkeit gleichermaßen reduzieren.

They do so for various important reasons, such as finding food and escaping predators. Observing these behaviors can inform us about the underlying cognitive processes. In addition, while humans can convey complicated information easily through speaking, animals need to move their bodies to communicate. This has prompted many creative solutions by animal neuroscientists to enable studying the brain during movement. In this review, we first summarize how animal researchers record from the brain while an animal is moving, by describing the most common neural recording techniques in animals and how they were adapted to record during movement. We further discuss the challenge of controlling or monitoring sensory input during free movement. However, not only is free movement a necessity to reflect the outcome of certain internal cognitive processes in animals, it is also a fascinating field of research since certain crucial behavioral patterns can only be observed and studied during free movement. Therefore, in a second part of the review, we focus on some key findings in animal research that specifically address the interaction between free movement and brain activity. First, focusing on walking as a fundamental form of free movement, we discuss how important such intentional movements are for understanding processes as diverse as spatial navigation, active sensing, and complex motor planning. Second, we propose the idea of regarding free movement as the expression of a behavioral state. This view can help to understand the general influence of movement on brain function. Together, the technological advancements towards recording from the brain during movement, and the scientific questions asked about the brain engaged in movement, make animal research highly valuable to research into the human “moving brain”.

In the present experiment, we tested the extent to which vocal demands (speaking) can affect pupil dilation. Based on corresponding preliminary evidence found in a reanalysis of an existing data set from our lab, we setup a new experiment that systematically investigated vocal response‐related effects compared to mere jaw/lip movement and button press responses. Conditions changed on a trial‐by‐trial basis while participants were instructed to keep fixating a central cross on a screen throughout. In line with our prediction (and previous observation), speaking caused the pupils to dilate strongest, followed by nonvocal movements and finally a baseline condition without any vocal or muscular demands. An additional analysis of blink rates showed no difference in blink frequency between vocal and baseline conditions, but different blink dynamics. Finally, simultaneously recorded electromyographic activity showed that muscle activity may contribute to some (but not all) aspects of the observed effects on pupil size. The results are discussed in the context of other recent research indicating effects of perceived (instead of executed) vocal action on pupil dynamics.

A direct replication attempt JF - Applied Cognitive Psychology N2 - Generated information is better recognized and recalled than information that is read. This so‐called generation effect has been replicated several times for different types of material, including texts. Perhaps the most influential demonstration was by McDaniel et al. (1986, Journal of Memory and Language, 25, 645–656; henceforth MEDC). This group tested whether the generation effect occurs only if the generation task stimulates cognitive processes not already stimulated by the text. Numerous studies, however, report difficulties replicating this text by generation‐task interaction, which suggests that the effect might only be found under conditions closer to the original method of MEDC. To test this assumption, we will closely replicate MEDC's Experiment 2 in German and English‐speaking samples.

Economical procedures are essential to identifying children with spelling problems as early as possible. Given the strong evidence showing that reading and spelling are based on the same orthographic knowledge, error-detection tasks (EDTs) could be considered such an economical procedure. Although EDTs are widely used in English-speaking countries, the few studies in German-speaking countries investigated only pupils in secondary school. The present study investigated N = 1,513 children in elementary school. We predicted spelling competencies (measured by dictation or gap-fill dictation) based on an EDT via linear regression. Error-detection abilities significantly predicted spelling competencies (R² between .509 and .679), indicating a strong connection. Predictive values in identifying children with poor spelling abilities with an EDT proved to be sufficient. Error detection for the assessment of spelling skills is therefore a valid instrument for transparent languages as well. N2 - Rechtschreibung zählt zu den Schlüsselkompetenzen für schulischen und beruflichen Erfolg. Um Kinder mit Rechtschreibproblemen adäquat zu unterstützen, ist eine frühe, möglichst niederschwellige Diagnostik essenziell. Aufgaben, in denen Rechtschreibfehler in präsentierten Texten zu identifizieren sind, könnten derartige ökonomische Verfahren darstellen. Obgleich Fehleridentifikationstests im angloamerikanischen Sprachraum weit verbreitet sind, haben sich die wenigen Studien im deutschsprachigen Raum bisher ausschließlich mit Kindern der Sekundarstufe beschäftigt. Die vorliegende Arbeit untersuchte in vier unabhängigen Studien N = 1.513 Grundschulkinder. Mittels linearer Regressionen wurden Rechtschreibkompetenzen (erhoben durch Fließ- und Lückendiktate) durch Leistungen in Fehleridentifikationstests vorhergesagt. Leistungen im Fehleridentifikationstest sagten Rechtschreibkompetenzen in allen Studien signifikant voraus (R² zwischen .509 und .679), was eine starke Assoziation der beiden Maße belegt. Prädiktive Werte zur Identifikation von Kindern mit schwachen Rechtschreibleistungen durch den Fehleridentifikationstest waren gut. Fehleridentifikation als Maß für Rechtschreibkompetenzen ist damit ein valides Instrument nicht nur für den angloamerikanischen Sprachraum, sondern auch für transparente Sprachen.

Participants played a virtual ball-tossing game with a stranger and a friend (friend condition) or a stranger and their romantic partner (partner condition) while being fully included, fully excluded, excluded only by the stranger, or excluded only by their close other. Replicating previous findings, full exclusion impaired participants’ basic-need satisfaction and relationship evaluation most severely.

Aims: This study aims at clarifying the issue by a multifaceted analysis of data from a large German sample. Method: A community sample of 406 bereaved persons answered the Wuerzburg Grief Inventory (WGI), a multidimensional grief questionnaire designed to measure normal grief in the German language, and the General Depression Scale – Short Version (GDS-S), a self-report depression scale. Data were analyzed by factor analysis to identify structural (dis-)similarities of the constructs, and analysis of variance (ANOVA) to identify the influence of the factors relationship to the deceased, type of death, and time since loss on grief measures and depression scores. Results: Factor analysis clustered items referring to grief-related impairments and depression into one factor, items referring to other dimensions of grief on separate factors, however. Relationship to the deceased influenced the grief measures impairments and nearness to the deceased, but not depression scores if controlled for impairments. Type of death showed specific effects on grief scores, but not on depression scores. Time since loss influenced grief scores, but not depression scores. Limitations: The analysis is based on a self-selected community sample of grieving persons, self-report measures, and in part, on cross-sectional data. Conclusion: Factor analysis and objective data show a clear distinction of dimensions of grief and depression. The human experience of grief contains a sense of nearness to the lost person, feelings of guilt, and positive aspects of the loss experience in addition to components resembling depression.

Steinbacher], Eva Katharina T1 - Gaze interaction: Cognitive mechanisms of oculomotor action control T1 - Blickinteraktion: Kognitive Mechanismen der okulomotorischen Handlungskontrolle N2 - Humans use their eyes not only as visual input devices to perceive the environment, but also as an action tool in order to generate intended effects in their environment. For instance, glances are used to direct someone else's attention to a place of interest, indicating that gaze control is an important part of social communication. Previous research on gaze control in a social context mainly focused on the gaze recipient by asking how humans respond to perceived gaze (gaze cueing). So far, this perspective has hardly considered the actor’s point of view by neglecting to investigate what mental processes are involved when actors decide to perform an eye movement to trigger a gaze response in another person. Furthermore, eye movements are also used to affect the non-social environment, for instance when unlocking the smartphone with the help of the eyes. This and other observations demonstrate the necessity to consider gaze control in contexts other than social communication whilst at the same time focusing on commonalities and differences inherent to the nature of a social (vs. non-social) action context. Thus, the present work explores the cognitive mechanisms that control such goal-oriented eye movements in both social and non-social contexts. The experiments presented throughout this work are built on pre-established paradigms from both the oculomotor research domain and from basic cognitive psychology. These paradigms are based on the principle of ideomotor action control, which provides an explanatory framework for understanding how goal-oriented, intentional actions come into being. The ideomotor idea suggests that humans acquire associations between their actions and the resulting effects, which can be accessed in a bi-directional manner: Actions can trigger anticipations of their effects, but the anticipated resulting effects can also trigger the associated actions. According to ideomotor theory, action generation involves the mental anticipation of the intended effect (i.e., the action goal) to activate the associated motor pattern. The present experiments involve situations where participants control the gaze of a virtual face via their eye movements. The triggered gaze responses of the virtual face are consistent to the participant’s eye movements, representing visual action effects. Experimental situations are varied with respect to determinants of action-effect learning (e.g., contingency, contiguity, action mode during acquisition) in order to unravel the underlying dynamics of oculomotor control in these situations. In addition to faces, conditions involving changes in non-social objects were included to address the question of whether mechanisms underlying gaze control differ for social versus non-social context situations. The results of the present work can be summarized into three major findings. 1. My data suggest that humans indeed acquire bi-directional associations between their eye movements and the subsequently perceived gaze response of another person, which in turn affect oculomotor action control via the anticipation of the intended effects. The observed results show for the first time that eye movements in a gaze-interaction scenario are represented in terms of their gaze response in others. This observation is in line with the ideomotor theory of action control. 2. The present series of experiments confirms and extends pioneering results of Huestegge and Kreutzfeldt (2012) with respect to the significant influence of action effects in gaze control. I have shown that the results of Huestegge and Kreutzfeldt (2012) can be replicated across different contexts with different stimulus material given that the perceived action effects were sufficiently salient. 3. Furthermore, I could show that mechanisms of gaze control in a social gaze-interaction context do not appear to be qualitatively different from those in a non-social context. All in all, the results support recent theoretical claims emphasizing the role of anticipation-based action control in social interaction. Moreover, my results suggest that anticipation-based gaze control in a social context is based on the same general psychological mechanisms as ideomotor gaze control, and thus should be considered as an integral part rather than as a special form of ideomotor gaze control. N2 - Der Mensch nutzt die Augen nicht nur zur Wahrnehmung seiner Umwelt, sondern auch als Handlungsinstrument, um intendierte Effekte in seiner Umwelt zu erzeugen. So werden Blicke beispielsweise dazu verwendet, die Aufmerksamkeit eines anderen auf einen bestimmten Ort zu lenken. Dies weist darauf hin, dass Blickkontrolle einen wichtigen Bestandteil in der sozialen Kommunikation darstellt. Die Forschung zu Blickkontrolle im sozialen Kontext hat sich bisher hauptsächlich auf den Blick-Empfänger konzentriert, um die Frage zu beantworten, wie Menschen auf wahrgenommene Blicke reagieren (Gaze Cueing). Dieser Ansatz hat dementsprechend bisher kaum den Standpunkt des Blick-Senders berücksichtigt. So wurde beispielsweise noch nicht untersucht, welche mentalen Prozesse der Ausübung einer Augenbewegung zugrunde liegen, die zum Ziel hat, bei einer anderen Person eine bestimmte Blickreaktion auszulösen. Darüber hinaus werden zielgerichtete Augenbewegungen auch im nicht-sozialen Kontext eingesetzt, beispielsweise beim Entsperren des Smartphones mithilfe der Augen. Diese und andere Beobachtungen zeigen allerdings klar die Notwendigkeit, Blickkontrolle sowohl in der sozialen Kommunikation als auch in anderen, nicht-sozialen Kontexten zu berücksichtigen und dabei gleichzeitig auf Gemeinsamkeiten und Unterschiede zu achten, die der Natur eines sozialen (vs. nicht-sozialen) Handlungskontextes innewohnen. Die vorliegende Arbeit untersucht daher die kognitiven Mechanismen, die solchen zielgerichteten Blickbewegungen in sozialen wie in nicht-sozialen Kontexten zugrunde liegen. Die in der vorliegenden Arbeit vorgestellten Experimente bauen auf bereits etablierten Paradigmen aus der Forschung zu Okulomotorik und zu basalen kognitiven Prozessen auf. Diese Paradigmen basieren auf dem Prinzip der ideomotorischen Handlungskontrolle, das eine Erklärung für die Entstehung zielgerichteter und beabsichtigter Handlungen liefert. Der ideomotorische Gedanke legt nahe, dass Menschen Assoziationen zwischen ihren Handlungen und den daraus resultierenden Effekten erwerben, die in zwei Richtungen wirken können: Eine Handlung kann die Antizipation ihrer Effekte auslösen, aber die aktive Antizipation eines Handlungseffektes kann auch die damit verbundene Handlung auslösen. Nach der ideomotorischen Theorie beinhaltet Handlungsgenerierung die mentale Antizipation des beabsichtigten Handlungseffektes, um das zugehörige motorische Muster zu aktivieren. Die vorliegenden Experimente beinhalten Situationen, in denen die Probanden den Blick eines virtuellen Gesichts mithilfe ihre eigenen Augenbewegungen steuern. Die im virtuellen Gesicht ausgelösten Blickreaktionen repräsentieren die visuellen Handlungseffekte. Die Situationen werden in Bezug auf die Determinanten von Handlungs-Effekt-Lernen (Kontingenz, Kontiguität, Handlungsmodus während des Lernens) variiert, um die zugrundeliegende Dynamik der okulomotorischen Handlungskontrolle in diesen Situationen zu verstehen. Zusätzlich zu den Gesichtern wurden Handlungseffekte in nicht-sozialen Objekten untersucht, um die Frage zu klären, ob sich die der Blickkontrolle zugrundeliegenden Mechanismen für soziale und nicht-soziale Kontextsituationen unterscheiden. Die Ergebnisse der vorliegenden Arbeit lassen sich in drei Hauptergebnisse zusammenfassen. 1. Meine Resultate legen nahe, dass Menschen bi-direktionale Assoziationen zwischen ihren Augenbewegungen und der darauf folgenden Blickreaktion einer anderen Person erwerben, was über die Antizipation der beabsichtigten Effekte die okulomotorische Handlungssteuerung beeinflusst. Die beobachteten Ergebnisse zeigen zum ersten Mal, dass Augenbewegungen in einem Blickinteraktionsszenario in Form einer bei der anderen Person ausgelösten Blickreaktion repräsentiert werden. Diese Beobachtung steht im Einklang mit dem ideomotorischen Prinzip der Handlungskontrolle. 2. Die vorliegende Versuchsreihe belegt und erweitert die wegweisenden Ergebnisse von Huestegge und Kreutzfeldt (2012) in Bezug auf den bedeutenden Einfluss von Handlungseffekten in der okulomotorischen Handlungskontrolle. Ich konnte zeigen, dass sich die Ergebnisse von Huestegge und Kreutzfeldt (2012) über verschiedene Kontexte mit unterschiedlichem Stimulus-Material replizieren lassen unter der Bedingung, dass die wahrgenommenen Handlungseffekte ausreichend stark ausgeprägt waren. 3. Zudem konnte ich zeigen, dass sich Mechanismen der Blickkontrolle in einem sozialen Blickinteraktionskontext vermutlich nicht qualitativ von denen in einem nicht-sozialen Kontext unterscheiden. Zusammenfassend unterstützen die Ergebnisse die jüngsten theoretischen Überlegungen, die die Rolle von antizipativen Prozessen in der Handlungssteuerung in sozialen Interaktionskontexten betonen. Darüber hinaus legen meine Ergebnisse nahe, dass antizipationsbasierte Blickkontrolle im sozialen Kontext auf den gleichen allgemeinen psychologischen Mechanismen wie ideomotorische Blickkontrolle basiert und somit als integraler Bestandteil, und nicht als eine spezielle Form der ideomotorischen Blickkontrolle, betrachtet werden sollte.

Our aim was to dissociate sensory driven bottom-up from cognitive top-down influences on blinking behavior and compare these influences between the auditory and the visual domain. Using an oddball paradigm, we found a significant pre-stimulus decrease in blink probability for visual input compared to auditory input. Sensory input further led to an early post-stimulus blink increase in both modalities if a task demanded attention to the input. Only visual input caused a pronounced early increase without a task. In case of a target or the omission of a stimulus (as compared to standard input), an additional late increase in blink rate was found in the auditory and visual domain. This suggests that blink modulation must be based on the interpretation of the input, but does not need any sensory input at all to occur. Our results show a complex modulation of blinking based on top-down factors such as prediction and attention in addition to sensory-based influences. The magnitude of the modulation is mainly influenced by general attentional demands, while the latency of this modulation allows to dissociate general from specific top-down influences that are independent of the sensory domain.

That project examined children’s comprehension of narrative text and its development in illustrated versus non-illustrated formats. For this purpose, van Dijk and Kintsch’s (1983) tri-partite model was used, according to which text recipients form text surface and textbase rep-resentations and construct a situation model. In particular, predictions referring to the influ-ence of illustrations on these three levels of text representation were derived from the inte-grated model of text and picture comprehension (ITPC; Schnotz, 2014), which holds that text-picture units are processed on both text-based (descriptive) and picture-based (depictive) paths. Accordingly, illustrations support the construction of a situation model. Moreover, in line with the embodied cognition account (e.g., Barsalou, 1999), it was assumed that the situa-tion model is grounded in perception and action; text recipients mentally simulate the situation addressed in the text through their neural systems related to perception (perceptual simulation) and action (motor resonance). Therefore, the thesis also examines whether perceptual simula-tion takes place during story reception, whether it improves the comprehension of illustrated stories, and whether motor resonance is related to the comprehension of text accompanied by dynamic illustrations. Finally, predictions concerning the development of comprehending illus-trated text were made in line with Springer’s (2001) hypotheses according to which younger children, compared with older children and adults, focus more on illustrations during text comprehension (perceptual boundedness) and use illustrations for the development of cogni-tive skills (perceptual support). The first research question sought to validate the tripartite model in the context of children’s comprehension of narrative text, so Hypothesis 1 predicted that children yield representations of the text surface, the textbase, and the situation model during text reception. The second research question comprised the assumptions regarding the impact of illustrations on text comprehension. Accordingly, it was expected that illustrations improve the situation model (Hypothesis 2a), especially when they are processed before their corresponding text passages (Hypothesis 2b). Both hypotheses were derived from the ITPC and the assumption that per-ceptual simulation supports the situation model. It was further predicted that dynamic illustra-tions evoke more accurate situation models than static ones (Hypothesis 2c); this followed from the assumption that motor resonance supports the situation model. In line with the ITPC, it was assumed that illustrations impair the textbase (Hypothesis 2d), especially when they are presented after their corresponding text passages (Hypothesis 2e). In accordance with earlier results, it was posited that illustrations have a beneficial effect for the text surface (Hypothesis 2f). The third research question addressed the embodied approach to the situation model. Here, it was assumed that perceptual simulation takes place during text reception (Hypothesis 3a) and that it is more pronounced in illustrated than in non-illustrated text (Hypothesis 3b); the latter hypothesis was related to a necessary premise of the assumption that perceptual sim-ulation improves the comprehension of illustrated text. The fourth research question was relat-ed to perceptual boundedness and perceptual support and predicted age-related differences; younger children were expected to benefit more from illustrations regarding the situation model (Hypothesis 4a) and to simulate vertical object movements in a more pronounced fash-ion (Hypothesis 4b) than older children. In addition, Hypothesis 4c held that perceptual simu-lation is more pronounced in younger children particularly when illustrations are present. Three experiments were conducted to investigate these hypotheses. Experiment 1 (Seger, Wannagat, & Nieding, submitted).compared the tripartite representations of written text without illustrations, with illustrations presented first, and with illustrations presented after their corresponding sentences. Students between 7 and 13 years old (N = 146) took part. Ex-periment 2 (Seger, Wannagat, & Nieding, 2019) investigated the tripartite representations of auditory text, audiovisual text with static illustrations, and audiovisual text with dynamic il-lustrations among children in the same age range (N = 108). In both experiments, a sentence recognition method similar to that introduced by Schmalhofer and Glavanov (1986) was em-ployed. This method enables the simultaneous measurement of all three text representations. Experiment 3 (Seger, Hauf, & Nieding, 2020) determined the perceptual simulation of vertical object movements during the reception of auditory and audiovisual narrative text among chil-dren between 5 and 11 years old and among adults (N = 190). For this experiment, a picture verification task based on Stanfield and Zwaan’s (2001) paradigm and adapted from Hauf (2016) was used. The first two experiments confirmed Hypothesis 1, indicating that the tripartite model is appli-cable to the comprehension of auditory and written narrative text among children. A benefi-cial effect of illustrations to the situation model was observed when they were presented syn-chronously with auditory text (Hypotheses 2a), but not when presented asynchronously with written text (Hypothesis 2b), so the ITPC is partly supported on this point. Hypothesis 2c was rejected, indicating that motor resonance does not make an additional contribution to the comprehension of narrative text with dynamic illustrations. Regarding the textbase, a general negative effect of illustrations was not observed (Hypothesis 2d), but a specific negative effect of illustrations that follow their corresponding text passages was seen (Hypothesis 2e); the latter result is also in line with the ITPC. The text surface (Hypothesis 2f) appears to benefit from illustrations in auditory but not written text. The results obtained in Experiment 3 sug-gest that children and adults perceptually simulate vertical object movements (Hypothesis 3a), but there appears to be no difference between auditory and audiovisual text (Hypothesis 3b), so there is no support for a functional relationship between perceptual simulation and the situ-ation model in illustrated text. Hypotheses 4a–4c were investigated in all three experiments and did not receive support in any of them, which indicates that representations of illustrated and non-illustrated narrative text remain stable within the age range examined here. N2 - Die vorliegende Doktorthesis ist Teil eines Forschungsprojektes zur Entwicklung des kogni-tiven Filmverständnisses an der Universität Würzburg, das von der Deutschen Forschungs-gemeinschaft im Zeitraum 2013 – 2019 als Zuwendung an Gerhild Nieding finanziert wurde. In diesem Projekt wurde das Verständnis narrativer Texte mit und ohne Illustrationen bei Kindern sowie dessen Entwicklung untersucht. Zu diesem Zweck wurde van Dijk und Kintschs (1983) Drei-Ebenen-Modell verwendet, demzufolge Textrezipient*innen eine Re-präsentation der Textoberfläche und der Textbasis bilden sowie ein Situationsmodell kon-struieren. Im Speziellen wurden Vorhersagen in Bezug auf den Einfluss von Illustrationen auf diese drei Textrepräsentationsebenen vom integrierten Modell des Text- und Bildver-ständnisses (ITPC; Schnotz, 2014) abgeleitet; dieses nimmt an, dass Text-Bild-Einheiten sowohl auf einem textbasierten (deskriptiven) als auch auf einem bildbasierten (depiktiven) Pfad verarbeitet werden. Demzufolge unterstützen Illustrationen den Aufbau eines Situati-onsmodells. Darüber hinaus wurde mit Bezug auf den Ansatz der verkörperten Kognition (z.B. Barsalou, 1999) angenommen, dass das Situationsmodell im Wahrnehmen und Han-deln begründet ist; Textrezipient*innen simulieren demnach die im Text dargestellte Situati-on durch die neuronalen Systeme, die mit Wahrnehmung (perzeptuelle Simulation) und Handlung (motorische Resonanz) in Verbindung stehen. Deshalb untersucht diese Thesis auch, ob perzeptuelle Simulation während der Textrezeption stattfindet, ob diese das Verste-hen illustrierter Geschichten verbessert und ob motorische Resonanz einen Bezug zum Ver-stehen von Texten mit dynamischen Illustrationen aufweist. Schließlich wurden Vorhersagen bezüglich der Entwicklung des Verständnisses illustrierter Texte anhand von Springers (2001) Hypothesen getroffen, wonach jüngere Kinder während des Textverstehens stärker auf Illustrationen fokussieren als ältere Kinder und Erwachsene (perzeptuelle Gebundenheit) und wonach sie Illustrationen für die Entwicklung kognitiver Fertigkeiten nutzen (perzeptu-elle Unterstützung). Die erste Forschungsfrage zielte darauf ab, das Drei-Ebenen-Modell im Zusammenhang mit dem Verständnis narrativer Texte bei Kindern zu validieren, daher sagte Hypothese 1 voraus, dass Kinder während der Textrezeption Repräsentationen der Textoberfläche, der Textbasis und des Situationsmodells aufweisen. Die zweite Forschungsfrage umfasste Annahmen be-züglich des Einflusses von Illustrationen auf das Textverständnis. Demnach wurde erwartet, dass Illustrationen das Situationsmodell verbessern (Hypothese 2a), vor allem, wenn diese vor den ihr jeweils zugeordneten Textpassagen verarbeitet werden (Hypothese 2b). Beide Hypothesen wurden hergeleitet aus dem ITPC sowie aus der Annahme, dass perzeptuelle Simulation das Situationsmodell unterstützt. Es wurde ferner vorhergesagt, dass dynamische Illustrationen genauere Situationsmodelle hervorrufen als statische (Hypothese 2c); dies folg-te aus der Annahme, dass motorische Resonanz das Situationsmodell unterstützt. In Überein-stimmung mit dem ITPC wurde angenommen, dass Illustrationen die Textbasis beeinträchti-gen (Hypothese 2d), vor allem, wenn diese nach den ihnen zugeordneten Textpassagen prä-sentiert werden (Hypothese 2e). Basierend auf früheren Ergebnissen wurde für die Textober-fläche die Hypothese aufgestellt, dass Illustrationen sich günstig auswirken (Hypothese 2f). Die dritte Forschungsfrage nahm Bezug auf den verkörperten Ansatz des Situationsmodells. Hierbei wurde postuliert, dass perzeptuelle Simulationen während der Textrezeption stattfin-den (Hypothese 3a) und dass diese stärker ausgeprägt sind bei illustriertem im Gegensatz zu nicht-illustriertem Text (Hypothese 3b); letztere Hypothese stand in Zusammenhang mit ei-ner notwendigen Voraussetzung der Annahme, dass perzeptuelle Simulation das Verständnis illustrierter Texte erhöht. Die vierte Forschungsfrage stand im Kontext der Annahmen perzeptueller Gebundenheit und perzeptueller Unterstützung und sagte Altersunterschiede voraus; es wurde erwartet, dass jüngere im Gegensatz älteren Kindern in Bezug auf das Situa-tionsmodell mehr von Illustrationen profitieren (Hypothese 4a) und vertikale Objektbewe-gungen stärker simulieren (Hypothese 4b). Zudem nahm Hypothese 4c an, dass die perzeptu-elle Simulation bei jüngeren Kindern vor allem dann stärker ausgeprägt ist, wenn Illustratio-nen gezeigt werden. Zur Überprüfung dieser Hypothesen wurden drei Experimente durchgeführt. Experiment 1 (Seger, Wannagat & Nieding, eingereicht) verglich die drei Repräsentationsebenen bei schriftlichem Text ohne Illustrationen, schriftlichem Text mit Illustrationen, die vor dem jeweiligen Text erschienen und schriftlichem Text mit Illustrationen, die danach erschienen. Schüler*innen im Alter von 7 bis 13 Jahren (N = 146) nahmen daran teil. Experiment 2 (Se-ger, Wannagat & Nieding, 2019) erforschte die drei Repräsentationsebenen bei auditivem Text, audiovisuellem Text mit statischen Illustrationen und audiovisuellem Text mit dyna-mischen Illustrationen in einer Stichprobe von Kindern desselben Alters (N = 108). In bei-den Experimenten wurde eine Satzrekognitionsmethode ähnlich der von Schmalhofer und Glavanov (1986) angewendet. Diese Methode ermöglicht die simultane Messung aller drei Repräsentationsebenen. Experiment 3 (Seger, Hauf & Nieding, 2020) untersuchte die perzep-tuelle Simulation von vertikalen Objektbewegungen bei der Rezeption auditiver und audio-visueller narrativer Texte bei Kindern im Alter von 5 bis 11 Jahren sowie bei Erwachsenen (N = 190). Hierbei wurde eine Bildverifikationsaufgabe verwendet, die auf Stanfield und Zwaans (2001) Paradigma aufbaut und von Hauf (2016) adaptiert wurde. Die ersten beiden Experimente bestätigen Hypothese 1, was darauf hindeutet, dass das Drei-Ebenen-Modell auf den Kontext des Verständnisses auditiver und schriftlicher narrativer Texte bei Kindern angewendet werden kann. Eine günstige Auswirkung von Illustrationen auf das Situationsmodell wurde beobachtet, wenn diese synchron mit auditivem Text (Hypo-these 2a), jedoch nicht wenn diese asynchron mit schriftlichem Text präsentiert wurden (Hy-pothese 2b); dies stellt eine partielle Bestätigung der ITPC in diesem Punkt dar. Hypothese 2c wurde verworfen, demnach trägt motorische Resonanz nicht zusätzlich zum Verständnis narrativer Texte mit dynamischen Illustrationen bei. Im Hinblick auf die Textbasis wurde kein genereller negativer Effekt von Illustrationen beobachtet (Hypothese 2d), jedoch ein spezifischer negativer Effekt wenn diese der ihnen jeweils zugeordneten Textpassage folgten (Hypothese 2e); letzteres Ergebnis steht ebenfalls im Einklang mit der ITPC. Die Textober-fläche (Hypothese 2f) scheint von Illustrationen bei auditivem, jedoch nicht bei schriftlichem Text zu profitieren. Die Ergebnisse von Experiment 3 legen nahe, dass Kinder und Erwach-sene vertikale Objektbewegungen perzeptuell simulieren (Hypothese 3a), es scheint jedoch diesbezüglich keinen Unterschied zwischen auditivem und audiovisuellem Text zu geben (Hypothese 3b); folglich wird die Annahme nicht unterstützt, dass perzeptuelle Simulationen beim Aufbau des Situationsmodells bei illustrierten Texten eine funktionale Rolle spielen. Die Hypothesen 4a–4c wurden in allen drei Experimenten untersucht und in keinem davon bestätigt; daraus folgt, dass Repräsentationen illustrierter und nicht illustrierter narrativer Texte innerhalb des untersuchten Altersbereichs stabil bleiben.

We were interested in whether facial expressions of the recipient in the dictator game influence dictators´ ehavior. To test this, we conducted an online study (n = 106) based on a modified version of a dictator game. The dictators allocated money between themselves and another person (recipient), who had no possibility to respond to the dictator. Importantly, before the allocation decision, the dictator was presented with the facial expression of the recipient (angry, disgusted, sad, smiling, or neutral). The results showed that dictators sent more money to recipients with sad or smiling facial expressions and less to recipients with angry or disgusted facial expressions compared with a neutral facial expression. Moreover, based on the sequential analysis of the decision and the interaction partner in the preceding trial, we found that decision-making depends upon previous interactions.

A dynamic view of body representations, however, holds that these representations cannot only be expanded but that they can also be narrowed down by disembodying elements of the body representation that are no longer warranted. Here we induced illusory ownership in terms of a moving rubber hand illusion and studied the maintenance of this illusion across different conditions. We observed ownership experience to decrease gradually unless participants continued to receive confirmatory multisensory input. Moreover, a single instance of multisensory mismatch – a hammer striking the rubber hand but not the real hand – triggered substantial and immediate disembodiment. Together, these findings support and extend previous theoretical efforts to model body representations through basic mechanisms of multisensory integration. They further support an updating model suggesting that embodied entities fade from the body representation if they are not refreshed continuously.

A1 - Wirth, Robert A1 - Kunde, Winfried T1 - Temporal binding past the Libet clock: testing design factors for an auditory timer JF - Behavior Research Methods N2 - Voluntary actions and causally linked sensory stimuli are perceived to be shifted towards each other in time. This so-called temporal binding is commonly assessed in paradigms using the Libet Clock. In such experiments, participants have to estimate the timing of actions performed or ensuing sensory stimuli (usually tones) by means of a rotating clock hand presented on a screen. The aforementioned task setup is however ill-suited for many conceivable setups, especially when they involve visual effects. To address this shortcoming, the line of research presented here establishes an alternative measure for temporal binding by using a sequence of timed sounds. This method uses an auditory timer, a sequence of letters presented during task execution, which serve as anchors for temporal judgments. In four experiments, we manipulated four design factors of this auditory timer, namely interval length, interval filling, sequence predictability, and sequence length, to determine the most effective and economic method for measuring temporal binding with an auditory timer.

T1 - A genome-wide association meta-analysis of prognostic outcomes following cognitive behavioural therapy in individuals with anxiety and depressive disorders JF - Translational Psychiatry N2 - Major depressive disorder and the anxiety disorders are highly prevalent, disabling and moderately heritable. Depression and anxiety are also highly comorbid and have a strong genetic correlation (r(g) approximate to 1). Cognitive behavioural therapy is a leading evidence-based treatment but has variable outcomes. Currently, there are no strong predictors of outcome. Therapygenetics research aims to identify genetic predictors of prognosis following therapy. We performed genome-wide association meta-analyses of symptoms following cognitive behavioural therapy in adults with anxiety disorders (n = 972), adults with major depressive disorder (n = 832) and children with anxiety disorders (n = 920; meta-analysis n = 2724). We (h(SNP)(2)) and polygenic scoring was used to examine genetic associations between therapy outcomes and psychopathology, personality and estimated the variance in therapy outcomes that could be explained by common genetic variants learning. No single nucleotide polymorphisms were strongly associated with treatment outcomes. No significant estimate of h(SNP)(2) could be obtained, suggesting the heritability of therapy outcome is smaller than our analysis was powered to detect. Polygenic scoring failed to detect genetic overlap between therapy outcome and psychopathology, personality or learning. This study is the largest therapygenetics study to date. Results are consistent with previous, similarly powered genome-wide association studies of complex traits.

This discrepancy, along with theoretical considerations, spawned doubts about the appropriateness of classical laboratory‐based experimental paradigms in social attention research. Several researchers instead suggested the use of immersive virtual scenarios in eliciting and measuring naturalistic attentional patterns, but the field, struggling with methodological challenges, still needs to establish the advantages of this approach. Here, we show using eye‐tracking in a complex social scenario displayed in virtual reality that participants show enhanced attention towards the face of an avatar at near distance and demonstrate an increased reactivity towards her social gaze as compared to participants who viewed the same scene on a computer monitor. The present study suggests that reactive virtual agents observed in immersive virtual reality can elicit natural modes of information processing and can help to conduct ecologically more valid experiments while maintaining high experimental control.

Recent Findings ToM, the capacity to reason about and infer others’ mental states, develops progressively throughout childhood—the exact time course is still a matter of debate. Neuroimaging studies indicate the involvement of a widespread neuronal network during mentalizing, suggesting that ToM is a multifaceted process. Accordingly, the tasks and trainings that currently exist to investigate and enhance ToM are heterogeneous, and the outcomes largely depend on the paradigm that was used. Summary We argue for the implementation of multiple-task batteries in the assessment of socio-cognitive abilities. Decisions for a particular paradigm need to be carefully considered and justified. We want to emphasize the importance of targeted research on the relationship between task specifications and outcomes.

Patients with clinically significant symptoms fulfilling at‐risk criteria for serious mental illness (SMI) require effective and safe treatment. Cognitive‐behavioral psychotherapy (CBT) has shown promising results in early stages of BD and in patients at high risk for psychosis. We aimed to investigate whether group CBT can improve symptoms and functional deficits in young patients at risk for SMI presenting with subthreshold bipolar symptoms. Method In a multicenter, randomized, controlled trial, patients at clinical risk for SMI presenting with subthreshold bipolar symptoms aged 15‐30 years were randomized to 14 weeks of at‐risk for BD‐specific group CBT or unstructured group meetings. Primary efficacy endpoints were differences in affective symptomatology and psychosocial functioning at 14 weeks. At‐risk status was defined as a combination of subthreshold bipolar symptomatology, reduction of psychosocial functioning and a family history for (schizo)affective disorders. A prespecified interim analysis was conducted at 75% of the targeted sample. Results Of 128 screened participants, 75 were randomized to group CBT (n = 38, completers = 65.8%) vs unstructured group meetings (n = 37, completers = 78.4%). Affective symptomatology and psychosocial functioning improved significantly at week 14 (P < .001) and during 6 months (P < .001) in both groups, without significant between‐group differences. Findings are limited by the interim character of the analysis, the use of not fully validated early detection interviews, a newly adapted intervention manual, and the substantial drop‐outs. Conclusions Results suggest that young patients at‐risk for SMI presenting with subthreshold bipolar symptoms benefit from early group sessions. The degree of specificity and psychotherapeutic interaction needed requires clarification.

The participants listened to a series of short narrative texts, in each of which a protagonist pursued a goal. Following each text, we collected the response time to a query word that was either associated with a near or a distant causal antecedent of the final sentence. Analysis of these response times indicated that audiovisual presentation has advantages over auditory presentation for accessing information relevant for establishing both local and global coherence, but there are indications that this effect may be slightly more pronounced for global coherence.

In the present paper, we evaluate and discuss how apparently trivial design choices of researchers may impact participants’ behavior and, consequently, a study’s results. We first provide a thorough comparison of mouse- and finger-tracking setups on the basis of a Simon task. We then vary a comprehensive set of design factors, including spatial layout, movement extent, time of stimulus onset, size of the target areas, and hit detection in a finger-tracking variant of this task. We explore the impact of these variations on a broad spectrum of movement parameters that are typically used to describe movement trajectories. Based on our findings, we suggest several recommendations for best practice that avoid some of the pitfalls of the methodology. Keeping these recommendations in mind will allow for informed decisions when planning and conducting future tracking experiments.

The neuropeptide oxytocin has been shown to modulate activity and functional connectivity in these brain regions, thereby optimizing the processing of emotional and neutral stimuli. To investigate whether oxytocin would be capable of attenuating BPD patients’ hypersensitivity for such stimuli, we recorded brain activity and gaze behavior during the processing of complex scenes in 51 females with and 48 without BPD after intranasal application of either oxytocin or placebo. We found divergent effects of oxytocin on BPD and healthy control (HC) participants’ (para-)limbic reactivity to emotional and neutral scenes: Oxytocin decreased amygdala and insula reactivity in BPD participants but increased it in HC participants, indicating an oxytocin-induced normalization of amygdala and insula activity during scene processing. In addition, oxytocin normalized the abnormal coupling between amygdala activity and gaze behavior across all scenes in BPD participants. Overall, these findings suggest that oxytocin may be capable of attenuating BPD patients’ hypersensitivity for complex scenes, irrespective of their valence.

Methods A total of 173 cancer patients suffering from mild to severe fatigue were randomly allocated to yoga intervention (n = 84) (IG) versus waitlist control group (CG) (n = 88). Yoga therapy consisted of eight weekly sessions with 60 min each. The primary outcome was self-reported fatigue symptoms. Secondary outcomes were symptoms of depression and quality of life (QoL). Data were assessed using questionnaires before (T0) and after yoga therapy for IG versus waiting period for CG (T1). Results A stronger reduction of general fatigue (P = .033), physical fatigue (P = .048), and depression (P < .001) as well as a stronger increase in QoL (P = .002) was found for patients who attended 7 or 8 sessions compared with controls. Within the yoga group, both higher attendance rate and lower T0-fatigue were significant predictors of lower T1-fatigue (P ≤ .001). Exploratory results revealed that women with breast cancer report a higher reduction of fatigue than women with other types of cancer (P = .016) after yoga therapy. Conclusion The findings support the assumption that yoga therapy is useful to reduce cancer-related fatigue, especially for the physical aspects of fatigue. Women with breast cancer seem to benefit most, and higher attendance rate results in greater reduction of fatigue.

In the well-established psychological refractory period (PRP) paradigm, tasks are triggered by two stimuli with a short temporal delay (stimulus onset asynchrony; SOA), thereby allowing control of the degree of task overlap. A decrease of the SOA reliably yields longer RTs of the task associated with the second stimulus (Task 2) while performance in the other task (Task 1) remains largely unaffected. This Task 2-specific SOA effect is usually interpreted in terms of central capacity limitations. Particularly, it has been assumed that response selection in Task 2 is delayed due to the allocation of less capacity until this process has been completed in Task 1. Recently, another important factor determining task prioritization has been proposed—namely, the particular effector systems associated with tasks. Here, we study both sources of task prioritization simultaneously by systematically combining three different effector systems (pairwise combinations of oculomotor, vocal, and manual responses) in the PRP paradigm. Specifically, we asked whether task order-based task prioritization (SOA effect) is modulated as a function of Task 2 effector system. The results indicate a modulation of SOA effects when the same (oculomotor) Task 1 is combined with a vocal versus a manual Task 2. This is incompatible with the assumption that SOA effects are solely determined by Task 1 response selection duration. Instead, they support the view that dual-task processing bottlenecks are resolved by establishing a capacity allocation scheme fed by multiple input factors, including attentional weights associated with particular effector systems.
