TY - JOUR A1 - Rodrigues, Johannes A1 - Marzban, Dorna A1 - Hewig, Johannes T1 - The influence of mental imagery expertise of pen and paper players versus computer gamers upon performance and electrocortical correlates in a difficult mental rotation task JF - Symmetry N2 - We investigated the influence of mental imagery expertise in 15 pen and paper role-players as an expert group compared to the gender-matched control group of computer role-players in the difficult Vandenberg and Kuse mental rotation task. 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.

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.

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.

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. Abschließend werden in dieser Arbeit die Möglichkeiten und die praktische Umsetzung dieser Technologie beschrieben und diskutiert. Dabei wird auch kritisch beleuchtet, inwiefern mit dieser Entwicklung auch in Zukunft noch eine konstruktive Einordnung von verschiedenen Laboruntersuchungen gewährleistet werden kann.

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. Die Implikationen für zukünftige Forschung und Praxis werden weiterführend diskutiert.

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. They highlight the importance of considering the personality of both interaction partner, as well as potential interactions of players' traits.

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.

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. Replicating the effect would suggest that it can be reproduced, at least under limited conditions, which will provide the necessary foundation for future investigations into the boundary conditions of this effect, with an eye towards its utility in applied contexts.

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.

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.

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.

However, not all patients respond to VRET, and some patients relapse after successful treatment. One explanation for this limitation of VRET is that its underlying mechanisms are not yet fully understood, leaving room for further improvement. On these grounds, the present thesis aimed to investigate two major research questions: first, it explored how virtual stimuli induce fear responses in height-fearful participants, and second, it tested if VRET outcome could be improved by incorporating techniques derived from two different theories of exposure therapy. To this end, five studies in virtual reality (VR) were conducted. Study 1 (N = 99) established a virtual environment for height exposure using a Computer Automatic Virtual Environment (CAVE) and investigated the effects of tactile wind simulation in VR. Height-fearful and non-fearful participants climbed a virtual outlook, and half of the participants received wind simulation. Results revealed that height-fearful participants showed stronger fear responses, on both a subjective and behavioral level, and that wind simulation increased subjective fear. However, adding tactile wind simulation in VR did not affect presence, the user's sense of 'being there' in the virtual environment. Replicating previous studies, fear and presence in VR were correlated, and the correlation was higher in height-fearful compared to non-fearful participants. Study 2 (N = 43) sought to corroborate the findings of the first study, using a different VR system for exposure (a head-mounted display) and measuring physiological fear responses. In addition, the effects of a visual cognitive distractor on fear in VR were investigated. Participants' fear responses were evident on both a subjective and physiological level---although much more pronounced on skin conductance than on heart rate---but the virtual distractor did not affect the strength of fear responses. In Study 3 (N = 50), the effects of trait height-fearfulness and height level on fear responses were investigated in more detail. Self-rated level of acrophobia and five different height levels in VR (1 m--20 m) were used as linear predictors of subjective and physiological indices of fear. Results showed that subjective fear and skin conductance responses were a function of both trait height-fearfulness and height level, whereas no clear effects were visible for heart rate. Study 4 (N = 64 + N = 49) aimed to advance the understanding of the relationship between presence and fear in VR. Previous research indicates a positive correlation between both measures, but possible causal mechanisms have not yet been identified. The study was the first to experimentally manipulate both presence (via the visual and auditive realism of the virtual environment) and fear (by presenting both height and control situations). Results indicated a causal effect of fear on presence, i.e., experiencing fear in a virtual environment led to a stronger sense of `being there' in the virtual environment. However, conversely, presence increased by higher scene realism did not affect fear responses. Nonetheless, presence seemed to have some effects on fear responding via another pathway, as participants whose presence levels were highest in the first safe context were also those who had the strongest fear responses in a later height situation. This finding indicated the importance of immersive user characteristics in the emergence of presence and fear in VR. The findings of the first four studies were integrated into a model of fear in VR, extending previous models and highlighting factors that lead to the emergence of both fear and presence in VR. Results of the studies showed that fear responses towards virtual heights were affected by trait height-fearfulness, phobic elements in the virtual environment, and, at least to some degree, on presence. Presence, on the other hand, was affected by experiencing fear in VR, immersion---the characteristics of the VR system---and immersive user characteristics. Of note, the manipulations of immersion used in the present thesis, visual and auditory realism of the virtual environment and tactile wind simulation, were not particularly effective in manipulating presence. Finally, Study 5 (N = 34) compared two different implementations of VRET for acrophobia to investigate mechanisms underlying its efficacy. The first implementation followed the Emotional Processing Theory, assuming that fear reduction during exposure is crucial for positive treatment outcome. In this condition, patients were asked to focus on their fear responses and on the decline of fear (habituation) during exposures. The second implementation was based on the inhibitory learning model, assuming that expectancy violation is the primary mechanism underlying exposure therapy efficacy. In this condition, patients were asked to focus on the non-occurrence of feared outcomes (e.g., 'I could fall off') during exposure. Based on predictions of the inhibitory learning model, the hypothesis for the study was that expectancy-violation-based exposure would outperform habituation-based exposure. After two treatment sessions in VR, both treatment conditions effectively reduced the patients' fear of heights, but the two conditions did not differ in their efficacy. The study replicated previous studies by showing that VRET is an effective treatment for acrophobia; however, contrary to the assumption, explicitly targeting the violation of threat expectancies did not improve outcome. This finding adds to other studies failing to provide clear evidence for expectancy violation as the primary mechanism underlying exposure therapy. Possible explanations for this finding and clinical implications are discussed, along with suggestions for further research. N2 - Die Expositionstherapie in virtueller Realität (VRET) ist ein wirksames kognitiv-verhaltenstherapeutisches Verfahren zur Behandlung von Angststörungen. Bei einer VRET werden Patienten nach psychoedukativer Vorbereitung mit virtuellen Repräsentationen der von ihnen gefürchteten Objekte oder Situationen konfrontiert. Die VRET zeigt allerdings nicht bei allen Patienten die gewünschte Wirksamkeit, und einige Patienten erleben selbst nach erfolgreicher Therapie eine Rückkehr der Angst. Da die zugrunde liegenden Wirkfaktoren der VRET noch nicht ausreichend aufgeklärt sind, lässt sich ihre Effektivtät möglicherweise noch weiter verbessern. Ziel der vorliegenden Arbeit war es daher zwei Fragen zu untersuchen. Zum einen, wie genau virtuelle Reize Furchtreaktionen bei höhenängstlichen Personen auslösen, und zum anderen, ob sich VRET durch den Einsatz spezifischer Techniken, welche aus Theorien zur Expositionstherapie abgeleitet wurden, verbessern lässt. Um die Fragen zu beantworten, wurden im Rahmen der Dissertation fünf Studien durchgeführt. In Studie 1 (N = 99) wurde eine virtuelle Umgebung für Höhenexposition etabliert und Effekte von taktiler Windsimulation in virtueller Realität (VR) untersucht. In der Studie hatten höhenängstliche und nicht-ängstliche Probanden die Aufgabe einen virtuellen Turm zu besteigen, wobei die Hälfte der Probanden währenddessen eine Windsimulation dargeboten bekam. Die Ergebnisse zeigten, dass höhenängstliche Probanden stärkere Furchtreaktionen zeigten, was sich sowohl im Bericht als auch im Verhalten äußerte. Zusätzlich erhöhte die Windsimulation die subjektiv Furcht der Probanden. Die Windsimulation hatte allerdings keinen Einfluss auf das Präsenzerleben, d. h. wie sehr sich Probanden so gefühlt hatten als seien sie tatsächlich in der virtuellen Umgebung gewesen. In der Studie konnten darüber hinaus zwei Befunde vorheriger Studien zum Präsenzerleben repliziert werden. Furcht und Präsenz korrelierten positiv, und dieser Zusammenhang war bei höhenängstlichen Probanden stärker als bei nicht-ängstlichen Probanden. Die Studie konnte zeigen, dass sich VR eignet um Furcht auf verschiedenen Reaktionsebenen zu untersuchen und es darüber hinaus möglich ist, Furcht in VR experimentell zu manipulieren. In Studie 2 (N = 43) sollten die Ergebnisse der ersten Studie bestätigt werden. Hierfür wurden ein anderes VR-System für die Exposition eingesetzt sowie die Erfassung von Furchtreaktionen um physiologische Maße ergänzt. Zusätzlich wurde der Einfluss einer visuell-kognitiven Distraktionsaufgabe in VR auf Furchtreaktionen untersucht. Die Furchtreaktionen der Probanden zeigten sich sowohl auf subjektiver als auch physiologischer Ebene, wobei Reaktionen der Hautleitfähigkeit stärker ausgeprägt waren als Veränderungen der Herzrate. Ein Einfluss der ablenkenden visuell-kognitiven Aufgabe auf Furchtreaktionen konnte nicht gezeigt werden. Die Studie konnte insgesamt verdeutlichen, dass die Eigenschaft von VR, Furcht zu erzeugen, nicht an einen bestimmten Versuchsaufbau gebunden ist und sich Furcht in VR auf allen Reaktionsebenen zeigt. Studie 3 (N = 50) hatte das Ziel, den Einfluss von Höhenängstlichkeit und Höhe auf Furchreaktionen genauer zu untersuchen. Hierfür wurde per Fragebogen erfasste Höhenängstlichkeit sowie fünf verschiedene Höhen (1 m--20 m) als lineare Prädiktoren für subjektive und physiologische Furchtindizes verwendet. Die Ergebnisse zeigten, dass subjektive Furcht und Hautleitfähigkeitsreaktionen in Abhängigkeit von sowohl Höhenängstlichkeit als auch Höhe zunahmen. Für die Herzrate zeigten sich hingegen keine eindeutigen Effekte. Die Studie konnte zusammenfassend zeigen, dass sich die Furchtreaktionen in VR spezifisch auf Höhe zeigten. In Studie 4 (N = 64 + N = 49) sollte der Zusammenhang zwischen Furcht und Präsenzerleben in VR genauer untersucht werden. Vorangegangene Studien zeigten eine positive Korrelation zwischen beiden Maßen, konnten jedoch keine Aussagen über einen möglichen Kausalzusammenhang machen. Die vorliegende Studie war daher die erste, welche sowohl Präsenz als auch Furcht experimentell manipulierte. Präsenz wurde über die Darbietung unterschiedlich realistischer virtueller Umgebungen, Furcht über die Darbietung von Höhen und Kontrollumgebungen manipuliert. Die Ergebnisse der Studie zeigten, dass es einen kausalen Effekt von Furcht auf Präsenzerleben gab, d. h. das Erleben von Furcht in einer Höhensituation in VR führte zu erhöhtem Präsenzerleben. Umgekehrt gab es jedoch keinen Effekt von experimentell manipuliertem Präsenzerleben auf die Stärke der Furchtreaktion. Es zeigte sich allerdings, dass Personen, welche in der ersten sicheren Situation das stärkste Präsenzerleben berichteten, später auch die stärksten Furchtreaktionen zeigten, was darauf schließen lässt, dass es möglicherwiese dennoch Effekte von Präsenzerleben auf Furcht gibt. Dieses Ergebnis weist auf die Bedeutung von möglichen Persönlichkeitsunterschieden hin, welche für das Erleben von Präsenz und Furcht in VR von Bedeutung sind. Die Studie verdeutlichte damit zum einen die Komplexität des Zusammenhangs zwischen Furcht und Präsenzerleben und erlaubte zum anderen erstmals Kausalschlüsse zwischen beiden Maßen. Die Ergebnisse der ersten vier Studien wurden in einem Modell zur Furcht in VR zusammengefasst. Basierend auf bestehenden Modellen zeigt das neue Modell Faktoren auf, welche für die Entstehung von Furcht und Präsenz bedeutsam sind. So konnten die Studien zeigen, dass Furchtreaktionen in Abhängigkeit von habitueller Höhenangst, der furchtbezogenen Relevanz der virtuellen Umgebung (z. B. Höhe), sowie zum Teil vom Präsenzerleben, auftreten. Bezüglich des Präsenzerlebens betont das Modell die Relevanz von aktuellem Furchterleben, Immersion (den Charakteristika des VR-Systems) und immersiven Nutzercharakteristika (z. B. Absorption). Zu erwähnen ist, dass die in der vorliegenden Dissertation untersuchten Manipulationen von Immersion (visueller und auditiver Realismus der virtuellen Umgebung und taktile Windsimulation) jedoch keine sonderlich starken Effekte auf Präsenz hatten. In Studie 5 (N = 34) wurden abschließend im Rahmen einer Therapiestudie zwei verschiedene VRET-Ansätze miteinander verglichen. Die erste Gruppe von Patienten erhielt hierbei eine Therapie auf Basis der Emotional Processing Theory. In dieser Bedingung wurden die Patienten während der Exposition gebeten, sich auf ihr Furchterleben und dessen Rückgang über die Zeit (Habituation) zu konzentrieren. Die zweite Gruppe von Patienten erhielt eine Therapie auf Basis des Inhibitory Learning Models. In dieser Bedingung wurden die Patienten gebeten, gezielt ihre Befürchtungen (z. B. "Ich könnte herunterfallen") zu überprüfen und zu widerlegen. Es wurde auf Basis der Vorhersage des Inhibitory Learning Models, dass Erwartungswiderlegung der zentrale Wirkfaktor der Expositionstherapie ist, angenommen, dass eine Therapie auf Basis der Widerlegung von Befürchtungen effektiver ist als eine Therapie auf Basis von Habituation. Nach zwei Therapiesitzungen berichteten die Patienten in beiden Gruppen einen signifikaten Rückgang ihrer Höhenangst, es zeigten sich jedoch keine Wirksamkeitsunterschiede zwischen den Gruppen. Die Studie konnte damit zwar vorherige Befunde replizieren, die zeigten, dass VRET eine effektive Behandlung für Höhenangst ist, die spezifische Fokussierung auf Erwartungswiderlegung zeigte jedoch keinen Vorteil. Dieser Befund reiht sich damit in eine Reihe von Studien ein, die Erwartungswiderlegung als zentralen Wirkfaktor der Expositionstherapie nicht nachweisen konnten. Mögliche Gründe für diesen Befund sowie daraus folgende klinische Implikationen und Vorschläge für weitere Forschung werden diskutiert.

Participants either pointed themselves or interpreted points while assuming the pointer’s or a typical observer perspective in a virtual reality environment. The perspective had a strong effect on the relationship between pointing gestures and referents, whereas the task had only a minor influence. This suggests that misunderstandings between pointers and observers primarily result from their typically different viewpoints.

Evidence for an averted-gaze advantage in a gaze-discrimination task JF - Attention, Perception, & Psychophysics N2 - Human eye gaze conveys an enormous amount of socially relevant information, and the rapid assessment of gaze direction is of particular relevance in order to adapt behavior accordingly. Specifically, previous research demonstrated evidence for an advantage of processing direct (vs. averted) gaze. The present study examined discrimination performance for gaze direction (direct vs. averted) under controlled presentation conditions: Using a backward-masking gaze-discrimination task, photographs of faces with direct and averted gaze were briefly presented, followed by a mask stimulus. Additionally, effects of facial context on gaze discrimination were assessed by either presenting gaze direction in isolation (i.e., by only showing the eye region) or in the context of an upright or inverted face. Across three experiments, we consistently observed a facial context effect with highest discrimination performance for faces presented in upright position, lower performance for inverted faces, and lowest performance for eyes presented in isolation. Additionally, averted gaze was generally responded to faster and with higher accuracy than direct gaze, indicating an averted-gaze advantage. Overall, the results suggest that direct gaze is not generally associated with processing advantages, thereby highlighting the important role of presentation conditions and task demands in gaze perception.

The current study tested conflict resolution styles and closeness as possible mediating factors. We hypothesized that trait mindfulness would increase the use of constructive conflict resolution styles (positive problem solving), decrease the use of destructive styles (conflict engagement, withdrawal, and compliance), and promote feelings of closeness between partners, which in turn would predict positive relationship outcomes (namely partnership quality, partnership satisfaction, and sexual satisfaction). Methods A total of 209 individuals (86% German, 76% female, mean age = 32 years) living in a relationship (31% married) participated in an online questionnaire. Results Mediation analyses revealed that positive problem solving mediated the association between mindfulness and partnership quality with b = .09 (95% CI = .03–.17), mindfulness and partnership satisfaction with b = .07 (95% CI = .02–.13), and mindfulness and sexual satisfaction with b = .04 (95% CI = .00–.10). Furthermore, a mediating role of withdrawal and closeness was shown for individual relationship outcomes. Conclusions Findings suggest that more positive problem solving, less withdrawal, and more closeness are mechanisms by which mindfulness is associated with positive relationship outcomes. The results of our study thus broaden our understanding of the processes that underlie fulfilling romantic relationships and, in turn, underline the positive effects of mindfulness.

This study examined how the credibility of the information source affects validation processes. Two experiments investigated combined effects of source credibility and plausibility of information during validation with explicit (ratings) and implicit (reading times) measurements. Participants read short stories with a high-credible versus low-credible person that stated a consistent or inconsistent assertion with general world knowledge. Ratings of plausibility and ratings of source credibility were lower when a credible source stated a world-knowledge inconsistent assertion compared with a low-credible source. Reading times on target sentences and on spillover sentences were slower when a credible source stated an assertion inconsistent with world knowledge compared with a low-credible source, suggesting that source information modulated the validation of implausible information. These results show that source credibility modulates validation and suggest a bidirectional relationship of perceived plausibility and source credibility in the reading process.

Such spatial binding can be construed as an implicit measure of object ownership, thus the belonging of a controlled object to the own body. The current study investigated how different transformations of hand movements (body-internal action component) into movements of a visual object (body-external action component) affect spatial action–effect binding, and thus implicit object ownership. In brief, participants had to bring a cursor on the computer screen into a predefined target position by moving their occluded hand on a tablet and had to estimate their final hand position. In Experiment 1, we found a significantly lower drift of the proprioceptive position of the hand towards the visual object when hand movements were transformed into laterally inverted cursor movements, rather than cursor movements in the same direction. Experiment 2 showed that this reduction reflected an elimination of spatial action–effect binding in the inverted condition. The results are discussed with respect to the prerequisites for an experience of ownership over artificial, noncorporeal objects. Our results show that predictability of an object movement alone is not a sufficient condition for ownership because, depending on the type of transformation, integration of the effector and a distal object can be fully abolished even under conditions of full controllability.

Particularly, threat imminence plays a major role for the organization of defensive responses. Acute threat prompts phasic physiological responses, which are usually associated with an intense feeling of fear. In contrast, diffuse and potentially threatening situations elicit a sustained state of anxious apprehension. Detection of the threatening stimulus defines the key event in this framework, initiating the transition from potential to acute threat. Consequently, attention to threat is crucial for supporting defensive behavior. The functions of attention are finely tuned to the characteristics of a threatening situation. Potential threat is associated with hypervigilance, in order to facilitate threat detection. Once a threatening stimulus has been identified, attention is selectively focused on the source of danger. Even though the concepts of selective attention and hypervigilance to threat are well established, evidence for their neural correlates remain scarce. Therefore, a major goal of this thesis is to elucidate the neural correlates of selective attention to acute threat and hypervigilance during potential threat. A second aim of this thesis is to provide a mechanistic account for the interaction of fear and anxiety. While contemporary models view fear and anxiety as mutually exclusive, recent findings for the neural networks of fear and anxiety suggest potential interactions. In four studies, aversive cue conditioning was used to induce acute threat, while context conditioning served as a laboratory model of potential threat. To quantify neural correlates of selective attention and hypervigilance, steady-state visual evoked potentials (ssVEPs) were measured as an index of visuocortical responding. Study 1 compared visuocortical responses to acute and potential threat for high versus low trait-anxious individuals. All individuals demonstrated enhanced electrocortical responses to the central cue in the acute threat condition, suggesting evidence for the neural correlate of selective attention. However, only low anxious individuals revealed facilitated processing of the contexts in the potential threat condition, reflecting a neural correlate of hypervigilance. High anxious individuals did not discriminate among contexts. These findings contribute to the notion of aberrational processing of potential threat for high anxious individuals. Study 2 and 3 realized orthogonal combinations of cue and context conditioning to investigate potential interactions of fear and anxiety. In contrast to Study 1 and 2, Study 3 used verbal instructions to induce potentially threatening contexts. Besides ssVEPs, threat ratings and skin conductance responses (SCRs) were recorded as efferent indices of defensive responding. None of these studies found further evidence for the neural correlates of hypervigilance and selective attention. However, results for ratings and SCRs revealed additive effects of fear and anxiety, suggesting that fear and anxiety are not mutually exclusive, but interact linearly to organize and facilitate defensive behavior. Study 4 tested ssVEPs to more ecologically valid forms of context conditioning, using flickering video stimuli of virtual offices to establish context representations. Contrary to expectations, results revealed decreased visuocortical responses during sustained presentations of anxiety compared to neutral contexts. A disruption of ssVEP signals eventually suggests interferences by continuously changing video streams which are enhanced as a function of motivational relevance. In summary, this thesis provided evidence for the neural correlates of attention only for isolated forms of fear and anxiety, but not for their interaction. In contrast, an additive interaction model of fear and anxiety for measures of defensive responding offers a new perspective on the topography of defensive behavior. N2 - ZusammenfassungDie Anpassung defensiver Verhaltensweisen an die Anforderungen bedrohlicher Sit-uationen ist eine fundamentale Funktion des Gehirns. Akute Bedrohung führt in der Regel zu kurz-anhaltenden, physiologischen Reaktionen, die mit einem Gefühlintensiver Furcht einhergehen, während Situationen potenzieller Bedrohung zu einem anhaltenden Zustand erhöhter Angst führen. Dabei spielt das Erkennen der Gefahr eine besondere Rolle, da sie den Übergang von potenzieller zu akuter Bedrohung initiiert. Demnach kommt der Aufmerksamkeit eine wichtige Funktion bei der Unterstützung defensiver Verhaltensweisen zu. Mechanismen der Aufmerksamkeit sind dabei präzise auf die jeweilige Situation abgestimmt. Potenzielle Bedrohung führt zu Hypervigilanz, um bedrohliche Reize schneller zu entdecken ...

Surprisingly, the role of somatosensory feedback for this phe-nomenon has been largely ignored. We fill this gap by showing that the somatosensory feedback, indexed by keypress peak force, is functional in judging keypress time. Specifically, the strength of somatosensory feedback is positively correlated with reported keypress time when the keypress is not associated with an auditory feedback and negatively correlated when the keypress triggers an auditory feedback. The result is consistent with the view that the reported keypress time is shaped by sensory information from different modalities. Moreover, individual differences in action binding can be explained by a sensory information weighting between somatosensory and auditory feedback. At the group level, increasing the strength of somatosensory feedback can decrease action binding to a level not being detected statistically. Therefore, a multisensory information integration account (between somatosensory and auditory inputs) explains action binding at both a group level and an individual level.

While previous research demonstrated binding for task-relevant, body-related effect features, the role of task-irrelevant or environment-related effect features in action planning is less clear. Here, we studied whether task-relevance or body-relatedness determines feature binding in action planning. Participants planned an action A, but before executing it initiated an intermediate action B. Each action relied on a body-related effect feature (index vs. middle finger movement) and an environment-related effect feature (cursor movement towards vs. away from a reference object). In Experiments 1 and 2, both effects were task-relevant. Performance in action B suffered from partial feature overlap with action A compared to full feature repetition or alternation, which is in line with binding of both features while planning action A. Importantly, this cost disappeared when all features were available but only body-related features were task-relevant (Experiment 3). When only the environment-related effect of action A was known in advance, action B benefitted when it aimed at the same (vs. a different) environment-related effect (Experiment 4). Consequently, the present results support the idea that task relevance determines whether binding of body-related and environment-related effect features takes place while the pre-activation of environment-related features without binding them primes feature-overlapping actions.

A pilot study JF - BMC Psychiatry N2 - Background: Although there is solid evidence for the efficacy of in vivo and virtual reality (VR) exposure therapy for a specific phobia, there is a significant debate over whether techniques promoting distraction or relaxation have impairing or enhancing effects on treatment outcome. In the present pilot study, we investigated the effect of diaphragmatic breathing (DB) as a relaxation technique during VR exposure treatment. Method: Twenty-nine patients with aviophobia were randomly assigned to VR exposure treatment either with or without diaphragmatic breathing (six cycles per minute). Subjective fear ratings, heart rate and skin conductance were assessed as indicators of fear during both the exposure and the test session one week later. Results: The group that experienced VR exposure combined with diaphragmatic breathing showed a higher tendency to effectively overcome the fear of flying. Psychophysiological measures of fear decreased and self-efficacy increased in both groups with no significant difference between the groups. Conclusions: Our findings indicate that diaphragmatic breathing during VR exposure does not interfere with the treatment outcome and may even enhance treatment effects of VR exposure therapy for aviophobic patients.

Unreflective actions differ from reflective, conscious actions in that the intentional description under which the agent knows what she is doing is not available or present to the agent at the moment of acting. Yet, unreflective actions belong to the field in which an agent experiences herself as capable of acting. Some unreflective actions, however, narrow this field and can be characterized by intentionality being inhibited. By studying inhibited intentionality in unreflective actions, the aim of the paper is to show how weaker forms of action urge us to expand our overall understanding of action. If we expand the field of actions such that it encompasses also some of the involuntary aspects of action, we are able to understand how unreflective actions can remain actions and do not fall under the scope of automatic behavior. With the notion of weak agency, the paper thus addresses one aspect of unreflective action, namely, “inhibited intentionality” in which an agent feels a diminished sense of authorship in relation to her possibility for self-understanding. The notion of weak agency clarifies how agency itself remains intact but can involve a process of appropriation of one’s actions as one’s own. With a diachronic account of consciousness in unreflective action, the paper accounts for possible self-understanding in cases where none seems available at the moment of action.

Previous studies suggest that humans are often unaware of the position or movements of their effective body part (mostly the hand) in such situations. It has been suggested that this might be due to a "haptic neglect" of bodily sensations to decrease the interference of representations of body and tool movements. However, in principle this interference could also be decreased by neglecting sensations regarding the tool and focusing instead on body movements. While in most tool use situations the tool-related action effects are task-relevant and thus suppression of body-related rather than tool-related sensations is more beneficial for successful goal achievement, we manipulated this task-relevance in a controlled experiment. The results showed that visual, tool-related effect representations can be suppressed just as proprioceptive, body-related ones in situations where effect representations interfere, given that task-relevance of body-related effects is increased relative to tool-related ones.

The current preregistered study investigated whether previously observed impairing effects of alcohol intoxication on participants' performance in a reaction time CIT (RT CIT) field study also translate to a laboratory environment. In contrast to the previous study of Suchotzki and Gamer (Sci Rep 8:7825, 2018) in which alcohol consumption was voluntary and self-administered, the current study used a randomized assignment of participants to either an alcohol group (n=88; receiving a drink with 3 cl alcohol) or a sober control group (n=89; receiving a drink with just some alcohol drops to hide group assignment). After drink administration, participants completed an RT CIT, in which they were instructed to hide knowledge of their own identity. Blood alcohol concentration (BAC) was estimated via breath alcohol ratio. In contrast to the previous field study, results revealed no differences in CIT-performance between intoxicated and sober participants. Aside from questioning the robustness of the result of the previous field study, our results also point to a number of interesting theoretical explanations for the discrepancy between both results, which are elaborated in the discussion.

The present study examined whether children learn new gender stereotypes from stories when unknown words are linked to a gendered protagonist or context information. In Experiment 1, 40 3‐ to 6‐year‐old preschoolers were read stories with either a gendered protagonist embedded within a non‐gendered context, or a non‐gendered protagonist embedded within a gendered context. In Experiment 2, the same sample of children were read stories with the protagonist and the context displaying congruent or incongruent gender information. Each story featured an unknown activity linked with the stereotypical content. Both experiments indicate that the children rated the activity according to both the gender of the context and of the protagonist; however, the effect of the latter was stronger. In addition, children showed higher interest in the unknown activity if the protagonist’s gender matched their own sex. Thus, gender information in stories influences how children perceive unknown words.

To counteract these developments, interventions aiming to increase PA are urgently needed. Mobile health (mHealth) solutions such as wearable sensors (wearables) may assist with an improvement in PA. Objective: The aim of this study is to examine which behavior change techniques (BCTs) are incorporated in currently available commercial high-end wearables that target users’ PA behavior. Methods: The BCTs incorporated in 5 different high-end wearables (Apple Watch Series 3, Garmin Vívoactive 3, Fitbit Versa, Xiaomi Amazfit Stratos 2, and Polar M600) were assessed by 2 researchers using the BCT Taxonomy version 1 (BCTTv1). Effectiveness of the incorporated BCTs in promoting PA behavior was assessed by a content analysis of the existing literature. Results: The most common BCTs were goal setting (behavior), action planning, review behavior goal(s), discrepancy between current behavior and goal, feedback on behavior, self-monitoring of behavior, and biofeedback. Fitbit Versa, Garmin Vívoactive 3, Apple Watch Series 3, Polar M600, and Xiaomi Amazfit Stratos 2 incorporated 17, 16, 12, 11, and 11 BCTs, respectively, which are proven to effectively promote PA. Conclusions: Wearables employ different numbers and combinations of BCTs, which might impact their effectiveness in improving PA. To promote PA by employing wearables, we encourage researchers to develop a taxonomy specifically designed to assess BCTs incorporated in wearables. We also encourage manufacturers to customize BCTs based on the targeted populations.

Here, we investigated the influence of state anger on punishment and compensation in the third‐party dictator game. Therefore, we used movie sequences for emotional priming, including the target states anger, happy, and neutral. We measured the Feedback‐Related Negativity (FRN) and midfrontal theta band activation, to investigate an electro‐cortical correlate of the processing of fair and unfair offers. Also, we assessed single‐trial FRN and midfrontal theta band activation as a predictor for punishment and compensation. We found that punishment was linked to state anger. Midfrontal theta band activation, which has previously been linked to altruistic acts and cognitive control, predicted less punishment. Additionally, trait anger led to enhanced FRN for unfair offers. This led to the interpretation that the FRN depicts the evaluation of fairness, while midfrontal theta band activation captures an aspect of cognitive control and altruistic motivation. We conclude that we need to redefine “altruistic punishment” into “costly punishment,” as no direct link of altruism and punishment is given. Additionally, midfrontal theta band activation complements the FRN and offers additional insights into complex responses and decision processes, especially as a single trial predictor.  KW - altruistic compensation KW - costly punishment KW - FRN KW - midfrontal theta activation KW - third party dictator game Y1 - 2020 U6 - http://nbn-resolving.de/urn/resolver.pl?urn:nbn:de:bvb:20-opus-214696 VL - 57 IS - 8 ER - TY - JOUR A1 - Eder, Andreas B.

Effects of observed emotional reactions on revenge seeking JF - Aggressive Behavior N2 - What reaction stops revenge taking? Four experiments (total N = 191) examined this question where the victim of an interpersonal transgression could observe the offender's reaction (anger, sadness, pain, or calm) to a retributive noise punishment. We compared the punishment intensity selected by the participant before and after seeing the offender's reaction. Seeing the opponent in pain reduced subsequent punishment most strongly, while displays of sadness and verbal indications of suffering had no appeasing effect. Expression of anger about a retributive punishment did not increase revenge seeking relative to a calm reaction, even when the anger response was disambiguated as being angry with the punisher. It is concluded that the expression of pain is the most effective emotional display for the reduction of retaliatory aggression. The findings are discussed in light of recent research on reactive aggression and retributive justice.

T1 - Overground Walking Decreases Alpha Activity and Entrains Eye Movements in Humans JF - Frontiers in Human Neuroscience N2 - Experiments in animal models have shown that running increases neuronal activity in early visual areas in light as well as in darkness. This suggests that visual processing is influenced by locomotion independent of visual input. Combining mobile electroencephalography, motion- and eye-tracking, we investigated the influence of overground free walking on cortical alpha activity (~10 Hz) and eye movements in healthy humans. Alpha activity has been considered a valuable marker of inhibition of sensory processing and shown to negatively correlate with neuronal firing rates. We found that walking led to a decrease in alpha activity over occipital cortex compared to standing. This decrease was present during walking in darkness as well as during light. Importantly, eye movements could not explain the change in alpha activity. Nevertheless, we found that walking and eye related movements were linked. While the blink rate increased with increasing walking speed independent of light or darkness, saccade rate was only significantly linked to walking speed in the light. Pupil size, on the other hand, was larger during darkness than during light, but only showed a modulation by walking in darkness. Analyzing the effect of walking with respect to the stride cycle, we further found that blinks and saccades preferentially occurred during the double support phase of walking. Alpha power, as shown previously, was lower during the swing phase than during the double support phase. We however could exclude the possibility that the alpha modulation was introduced by a walking movement induced change in electrode impedance. Overall, our work indicates that the human visual system is influenced by the current locomotion state of the body. This influence affects eye movement pattern as well as neuronal activity in sensory areas and might form part of an implicit strategy to optimally extract sensory information during locomotion.

As a consequence, this information will be more likely to become the basis for the absolute judgment which will therefore be assimilated toward the anchor. However, if the activated information overlaps with information that is elicited by the absolute judgment itself, the preceding comparative judgment should not exert an incremental effect and should fail to result in an anchoring effect. The present studies find this result when the comparative judgment refers to a general category and the absolute judgment refers to a subset of the general category that was activated by the anchor value. For example, participants comparing the average annual temperature in New York City to a high 102 °F judged the average winter, but not summer temperature to be higher than participants making no comparison. On the other hand, participants comparing the annual temperature to a low –4 °F judged the average summer, but not winter temperature to be lower than control participants. This pattern of results was shown also in another content domain. It is consistent with the Selective Accessibility Model but difficult to reconcile with other main explanations of the anchoring effect.

Since the DG contains an inherent dominance gradient, we examined the relationship between dictator decisions and recipient status, which was operationalized by three social identities and an artificial intelligence (AI). Additionally, we examined the predictive value of social dominance orientation (SDO) on the behavior of dictators toward the different social and non-social hierarchical recipients. A multilevel model analysis showed that recipients with the same status as the dictator benefited the most and the artificial intelligence the least. Furthermore, SDO, regardless of social status, predicted behavior toward recipients in such a way that higher dominance was associated with lower dictator offers. In summary, participants treated other persons of higher and lower status equally, those of equal status better and, above all, an algorithm worst. The large proportion of female participants and the limited variance of SDO should be taken into account with regard to the results of individual differences in SDO.

A1 - Pauli, Paul A1 - Reicherts, Philipp T1 - Acceptance-Based Emotion Regulation Reduces Subjective and Physiological Pain Responses JF - Frontiers in Psychology N2 - Acceptance-based regulation of pain, which focuses on the allowing of pain and pain related thoughts and emotions, was found to modulate pain. However, results so far are inconsistent regarding different pain modalities and indices. Moreover, studies so far often lack a suitable control condition, focus on behavioral pain measures rather than physiological correlates, and often use between-subject designs, which potentially impede the evaluation of the effectiveness of the strategies. Therefore, we investigated whether acceptance-based strategies can reduce subjective and physiological markers of acute pain in comparison to a control condition in a within-subject design. To this end, participants (N = 30) completed 24 trials comprising 10 s of heat pain stimulation. Each trial started with a cue instructing participants to welcome and experience pain (acceptance trials) or to react to the pain as it is without employing any regulation strategies (control trials). In addition to pain intensity and unpleasantness ratings, heart rate (HR) and skin conductance (SC) were recorded. Results showed significantly decreased pain intensity and unpleasantness ratings for acceptance compared to control trials. Additionally, HR was significantly lower during acceptance compared to control trials, whereas SC revealed no significant differences. These results demonstrate the effectiveness of acceptance-based strategies in reducing subjective and physiological pain responses relative to a control condition, even after short training. Therefore, the systematic investigation of acceptance in different pain modalities in healthy and chronic pain patients is warranted.

Non-visual BCI paradigms, however, may be required for patients who struggle with vision dependent BCIs because of a loss of gaze control. With the present study, we attempted to replicate earlier results by Herweg et al. (2016), with several minor adjustments and a focus on training effects and usability. We invited 16 healthy participants and trained them with a 4-class tactile P300-based BCI in five sessions. Their main task was to navigate a virtual wheelchair through a 3D apartment using the BCI. We found significant training effects on information transfer rate (ITR), which increased from a mean of 3.10–9.50 bits/min. Further, both online and offline accuracies significantly increased with training from 65% to 86% and 70% to 95%, respectively. We found only a descriptive increase of P300 amplitudes at Fz and Cz with training. Furthermore, we report subjective data from questionnaires, which indicated a relatively high workload and moderate to high satisfaction. Although our participants have not achieved the same high performance as in the Herweg et al. (2016) study, we provide evidence for training effects on performance with a tactile BCI and confirm the feasibility of the paradigm.

A central hypothesis of the present paper is that data visualizations should be adapted to both the user and the context. This idea was initially addressed in Study 1, which demonstrated substantial interindividual variability among a group of experts when freely choosing an option to visualize data sets. To lay the theoretical groundwork for a systematic, taxonomic approach, a user model combining user traits, states, strategies, and actions was proposed and further evaluated empirically in Studies 2 and 3. The results implied that for adapting to user traits, statistical expertise is a relevant dimension that should be considered. Additionally, for adapting to user states different user intentions such as monitoring and analysis should be accounted for. These results were used to develop a taxonomy which adapts visualization recommendations to these (and other) factors. A preliminary attempt to validate the taxonomy in Study 4 tested its visualization recommendations with a group of experts. While the corresponding results were somewhat ambiguous overall, some aspects nevertheless supported the claim that a user-adaptive data visualization approach based on the principles outlined in the taxonomy can indeed be useful. While the present approach to user adaptivity is still in its infancy and should be extended (e.g., by testing more participants), the general approach appears to be very promising.

In addition, it was investigated whether these differences can be observed at the behavioural level via spontaneous facial muscle activity. Emotional content of the stimuli did not affect early P1 activity. Emotional faces elicited enhanced amplitudes of the face-sensitive N170 component, while its counterpart, the scene-related N100, was not sensitive to emotional content of scenes. At 220-280 ms, the early posterior negativity (EPN) was enhanced only slightly for fearful as compared to neutral or happy faces. However, its amplitudes were significantly enhanced during processing of scenes with positive content, particularly over the right hemisphere. Scenes of positive content also elicited enhanced spontaneous zygomatic activity from 500-750 ms onwards, while happy faces elicited no such changes. Contrastingly, both fearful faces and negative scenes elicited enhanced spontaneous corrugator activity at 500-750 ms after stimulus onset. However, relative to baseline EMG changes occurred earlier for faces (250 ms) than for scenes (500 ms) whereas for scenes activity changes were more pronounced over the whole viewing period. Taking into account all effects, the data suggests that emotional facial expressions evoke faster attentional orienting, but weaker affective neural activity and emotional behavioural responses compared to emotional scenes.

T1 - Psychological placebo and nocebo effects on pain rely on expectation and previous experience JF - Journal of Pain N2 - Expectation and previous experience are both well established key mediators of placebo and nocebo effects. However, the investigation of their respective contribution to placebo and nocebo responses is rather difficult because most placebo and nocebo manipulations are contaminated by pre-existing treatment expectancies resulting from a learning history of previous medical interventions. To circumvent any resemblance to classical treatments, a purely psychological placebonocebo manipulation was established, namely, the "visual stripe pattern induced modulation of pain." To this end, experience and expectation regarding the effects of different visual cues (stripe patterns) on pain were varied across 3 different groups, with either only placebo instruction (expectation), placebo conditioning (experience), or both (expectation + experience) applied. Only the combined manipulation (expectation + experience) revealed significant behavioral and physiological placebo nocebo effects on pain. Two subsequent experiments, which, in addition to placebo and nocebo cues, included a neutral control condition further showed that especially nocebo responses were more easily induced by this psychological placebo and nocebo manipulation. The results emphasize the great effect of psychological processes on placebo and nocebo effects. Particularly, nocebo effects should be addressed more thoroughly and carefully considered in clinical practice to prevent the accidental induction of side effects.

Wenn wir aus eigenen Stücken oder inspiriert durch unsere Umwelt Handlungen vorbereiten die unseren aktuellen Zielen entgegen stehen, kommt es zu Konflikten. Solche Konflikte können sich auf nachfolgendes Erleben und Verhalten auswirken. Aversive Konsequenzen von Konflikt könnten in einem Konfliktüberwachungsmodul registriert werden, welches anschließend Aufmerksamkeitsänderungen und Handlungstendenzen zur Reduzierung dieses negativen Affektes in Gang setzt. Wenn das der Fall wäre, könnten die vielfach beobachteten Verhaltensanpassungen an kognitiven Konflikt ein Ausdruck von Emotionsregulation sein. Ein theoretischer Eckpfeiler der gegenwärtigen Forschung zur Emotionsregulation ist das Prozessmodell der Emotionsregulation, das aus den Regulationsstrategien Situationsauswahl, Situationsmodifikation, Aufmerksamkeitslenkung, kognitiven Veränderungen und Reaktionsmodulation besteht. Unter der Annahme, dass Konfliktanpassung und Affektregulation auf gemeinsamen Mechanismen fußen, habe ich aus dem Prozessmodell der Emotionsregulation Vorhersagen zur kognitiven Kontrolle abgeleitet und diese in elf Experimenten getestet (N = 509). Die Versuchsteilnehmer zeigten Situationsauswahl in Bezug auf Konflikte, allerdings nur dann, wenn sie ausdrücklich auf Handlungs- und Ergebniskontingenzen hingewiesen wurden (Experimente 1 bis 3). Ich fand Anzeichen für einen Mechanismus, der der Situationsmodifikation ähnelt, aber keine Hinweise auf eine Beteiligung von Affekt (Experimente 4 bis 10). Eine Änderung der Konfliktbewertung hatte keinen Einfluss auf das Ausmaß der Konfliktadaptation (Experiment 11). Insgesamt gab es Hinweise auf eine explizite Aversivität kognitiver Konflikte, jedoch weniger auf implizite Aversivität, was darauf hindeutet, dass Konflikte vor allem dann Affektregulationsprozesse auslösen, wenn Menschen explizit Affektregulationsziele vor Augen haben. N2 - Cognitive control is what makes goal-directed actions possible. Whenever the environment or our impulses strongly suggests a response that is incompatible with our goals, conflict arises. Such conflicts are believed to cause negative affect. Aversive consequences of conflict may be registered in a conflict monitoring module, which subsequently initiates attentional changes and action tendencies to reduce negative affect. This association suggests that behavioral adaptation might be a reflection of emotion regulation. The theoretical cornerstone of current research on emotion regulation is the process model of emotion regulation, which postulates the regulation strategies situation selection, situation modification, attentional deployment, cognitive change, and response modulation. Under the assumption that conflict adaptation and affect regulation share common mechanisms, I derived several predictions regarding cognitive control from the process model of emotion regulation and tested them in 11 experiments (N = 509). Participants engaged in situation selection towards conflict, but only when they were explicitly pointed to action-outcome contingencies (Experiments 1 to 3). I found support for a mechanism resembling situation modification, but no evidence for a role of affect (Experiments 4 to 10). Changing the evaluation of conflict had no impact on the extent of conflict adaptation (Experiment 11). Overall, there was evidence for an explicit aversiveness of cognitive conflict, but less evidence for implicit aversiveness, suggesting that conflict may trigger affect regulation processes, particularly when people explicitly have affect regulation goals in mind.

T1 - Mismatch or allostatic load? Timing of life adversity differentially shapes gray matter volume and anxious temperament JF - Social Cognitive and Affective Neuroscience N2 - Traditionally, adversity was defined as the accumulation of environmental events (allostatic load). Recently however, a mismatch between the early and the later (adult) environment (mismatch) has been hypothesized to be critical for disease development, a hypothesis that has not yet been tested explicitly in humans. We explored the impact of timing of life adversity (childhood and past year) on anxiety and depression levels (N = 833) and brain morphology (N = 129). Both remote (childhood) and proximal (recent) adversities were differentially mirrored in morphometric changes in areas critically involved in emotional processing (i.e. amygdala/hippocampus, dorsal anterior cingulate cortex, respectively). The effect of adversity on affect acted in an additive way with no evidence for interactions (mismatch). Structural equation modeling demonstrated a direct effect of adversity on morphometric estimates and anxiety/depression without evidence of brain morphology functioning as a mediator. Our results highlight that adversity manifests as pronounced changes in brain morphometric and affective temperament even though these seem to represent distinct mechanistic pathways. A major goal of future studies should be to define critical time periods for the impact of adversity and strategies for intervening to prevent or reverse the effects of adverse childhood life experiences.
