TY - THES A1 - Liesner, Marvin Paul T1 - I control it, but does it mean it is part of me? 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.
