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.}, language = {en} } @article{SchindlerRichterMar2021, author = {Schindler, Julia and Richter, Tobias and Mar, Raymond}, title = {Does generation benefit learning for narrative and expository texts?

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.

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.}, language = {en} } @article{MitschkeEder2021, author = {Mitschke, Vanessa and Eder, Andreas B.}, title = {Facing the enemy: Spontaneous facial reactions towards suffering opponents}, series = {Psychophysiology}, volume = {58}, journal = {Psychophysiology}, number = {8}, doi = {10.1111/psyp.13835}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-259672}, year = {2021}, abstract = {The suffering of an opponent is an important social affective cue that modulates how aggressive interactions progress.

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.

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.

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.}, language = {en} } @article{RodriguesMarzbanHewig2021, author = {Rodrigues, Johannes and Marzban, Dorna and Hewig, Johannes}, title = {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}, series = {Symmetry}, volume = {13}, journal = {Symmetry}, number = {12}, issn = {2073-8994}, doi = {10.3390/sym13122337}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-252253}, year = {2021}, abstract = {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.

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.

For instance, glances are used to direct someone else's attention to a place of interest, indicating that gaze control is an important part of social communication. Previous research on gaze control in a social context mainly focused on the gaze recipient by asking how humans respond to perceived gaze (gaze cueing). So far, this perspective has hardly considered the actor's point of view by neglecting to investigate what mental processes are involved when actors decide to perform an eye movement to trigger a gaze response in another person. Furthermore, eye movements are also used to affect the non-social environment, for instance when unlocking the smartphone with the help of the eyes. This and other observations demonstrate the necessity to consider gaze control in contexts other than social communication whilst at the same time focusing on commonalities and differences inherent to the nature of a social (vs. non-social) action context. Thus, the present work explores the cognitive mechanisms that control such goal-oriented eye movements in both social and non-social contexts. The experiments presented throughout this work are built on pre-established paradigms from both the oculomotor research domain and from basic cognitive psychology. These paradigms are based on the principle of ideomotor action control, which provides an explanatory framework for understanding how goal-oriented, intentional actions come into being. The ideomotor idea suggests that humans acquire associations between their actions and the resulting effects, which can be accessed in a bi-directional manner: Actions can trigger anticipations of their effects, but the anticipated resulting effects can also trigger the associated actions. According to ideomotor theory, action generation involves the mental anticipation of the intended effect (i.e., the action goal) to activate the associated motor pattern. The present experiments involve situations where participants control the gaze of a virtual face via their eye movements. The triggered gaze responses of the virtual face are consistent to the participant's eye movements, representing visual action effects. Experimental situations are varied with respect to determinants of action-effect learning (e.g., contingency, contiguity, action mode during acquisition) in order to unravel the underlying dynamics of oculomotor control in these situations. In addition to faces, conditions involving changes in non-social objects were included to address the question of whether mechanisms underlying gaze control differ for social versus non-social context situations. The results of the present work can be summarized into three major findings. 1. My data suggest that humans indeed acquire bi-directional associations between their eye movements and the subsequently perceived gaze response of another person, which in turn affect oculomotor action control via the anticipation of the intended effects. The observed results show for the first time that eye movements in a gaze-interaction scenario are represented in terms of their gaze response in others. This observation is in line with the ideomotor theory of action control. 2. The present series of experiments confirms and extends pioneering results of Huestegge and Kreutzfeldt (2012) with respect to the significant influence of action effects in gaze control. I have shown that the results of Huestegge and Kreutzfeldt (2012) can be replicated across different contexts with different stimulus material given that the perceived action effects were sufficiently salient. 3. Furthermore, I could show that mechanisms of gaze control in a social gaze-interaction context do not appear to be qualitatively different from those in a non-social context. All in all, the results support recent theoretical claims emphasizing the role of anticipation-based action control in social interaction. Moreover, my results suggest that anticipation-based gaze control in a social context is based on the same general psychological mechanisms as ideomotor gaze control, and thus should be considered as an integral part rather than as a special form of ideomotor gaze control.}, subject = {Verhaltenskontrolle}, language = {en} } @article{KrishnaRiedMeixner2021, author = {Krishna, Anand and Ried, Sophia and Meixner, Marie}, title = {State-trait interactions in regulatory focus determine impulse buying behavior}, series = {PLoS One}, volume = {16}, journal = {PLoS One}, number = {7}, doi = {10.1371/journal.pone.0253634}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-261206}, year = {2021}, abstract = {Little research has focused on motivational state-trait interactions to explain impulse buying.

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.

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.

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.}, subject = {Textverstehen}, language = {en} } @article{LiesnerKunde2021, author = {Liesner, Marvin and Kunde, Wilfried}, title = {Environment-Related and Body-Related Components of the Minimal Self}, series = {Frontiers in Psychology}, volume = {12}, journal = {Frontiers in Psychology}, issn = {1664-1078}, doi = {10.3389/fpsyg.2021.712559}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-250007}, year = {2021}, abstract = {Perceptual changes that an agent produces by efferent activity can become part of the agent's minimal self.

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.

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.}, subject = {Erm{\"u}dungssyndrom}, language = {en} } @phdthesis{Schmidts2021, author = {Schmidts, Constantin}, title = {Affective regulation of cognitive conflict}, doi = {10.25972/OPUS-21989}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-219897}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2021}, abstract = {Kognitive Kontrolle beschreibt Prozesse die n{\"o}tig sind um zielgerichtetes Handeln im Angesicht von internen oder externen Widerst{\"a}nden zu erm{\"o}glichen.

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.}, language = {en} } @article{BrychHaendelRiechelmannetal.2021, author = {Brych, Mareike and H{\"a}ndel, Barbara F. and Riechelmann, Eva and Pieczykolan, Aleksandra and Huestegge, Lynn}, title = {Effects of vocal demands on pupil dilation}, series = {Psychophysiology}, volume = {58}, journal = {Psychophysiology}, number = {2}, doi = {10.1111/psyp.13729}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-224425}, year = {2021}, abstract = {Pupil dilation is known to be affected by a variety of factors, including physical (e.g., light) and cognitive sources of influence (e.g., mental load due to working memory demands, stimulus/response competition etc.).

Conditions changed on a trial-by-trial basis while participants were instructed to keep fixating a central cross on a screen throughout.

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.}, subject = {Furcht}, language = {en} } @article{KirschKundeHerbort2021, author = {Kirsch, Wladimir and Kunde, Wilfried and Herbort, Oliver}, title = {Impact of proprioception on the perceived size and distance of external objects in a virtual action task}, series = {Psychonomic Bulletin \& Review}, volume = {28}, journal = {Psychonomic Bulletin \& Review}, number = {4}, issn = {1531-5320}, doi = {10.3758/s13423-021-01915-y}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-273235}, pages = {1191-1201}, year = {2021}, abstract = {Previous research has revealed changes in the perception of objects due to changes of object-oriented actions.

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.

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.

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.}, language = {en} } @article{WeissPaeleckeHewig2021, author = {Weiß, Martin and Paelecke, Marko and Hewig, Johannes}, title = {In Your Face(t) — Personality Traits Interact With Prototypical Personality Faces in Economic Decision Making}, series = {Frontiers in Psychology}, volume = {12}, journal = {Frontiers in Psychology}, issn = {1664-1078}, doi = {10.3389/fpsyg.2021.652506}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-237051}, year = {2021}, abstract = {In everyday life, assumptions about our peers' as well as our own personality shape social interactions.

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.

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.}, language = {en} } @article{PfisterKlaffehnKalckertetal.2021, author = {Pfister, Robert and Klaffehn, Annika L. and Kalckert, Andreas and Kunde, Winfried and Dignath, David}, title = {How to lose a hand: Sensory updating drives disembodiment}, series = {Psychonomic Bulletin \& Review}, volume = {28}, journal = {Psychonomic Bulletin \& Review}, issn = {1069-9384}, doi = {10.3758/s13423-020-01854-0}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-235195}, pages = {827-833}, year = {2021}, abstract = {Body representations are readily expanded based on sensorimotor experience.

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.

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.

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.

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.}, language = {en} } @article{SegerWannagatNieding2021, author = {Seger, Benedikt T. and Wannagat, Wienke and Nieding, Gerhild}, title = {Children's surface, textbase, and situation model representations of written and illustrated written narrative text}, series = {Reading and Writing}, volume = {34}, journal = {Reading and Writing}, number = {6}, issn = {1573-0905}, doi = {10.1007/s11145-020-10118-1}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-269813}, pages = {1415-1440}, year = {2021}, abstract = {According to the tripartite model of text representation (van Dijk \& Kintsch, 1983), readers form representations of the text surface and textbase, and construct a situation model.

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.

Methods Patient-reported ASKp, clinician-reported Karnofsky/Lansky status (KPS/PSS), patient characteristics and cGVHD details were assessed of 55 patients with a median age of 12 years at baseline after day +100 post-HSCT and every 3 months during the next 18 months. The psychometric properties were evaluated and ASKp and KPS/PSS status was compared using ANOVAS and multiple regression models. Results The German version of the ASKp showed good psychometric properties except for ceiling effects. Discrimination ability of the ASKp was good regarding the need for devices but failed to predict cGVHD patients. Both the ASKp and the KPS/PSS were associated with patients after adoptive cell therapy being in need for devices, suffering from overlap cGVHD and from steroid side effects but not with patients' age and gender. In contrast to the KPS/PSS the ASKp only showed significant differences after merging moderate and severe cGHVD patients when comparing them to No-cGVHD (F = 4.050; p = 0.049), being outperformed by the KPS/PSS (F = 20.082; p < 0.001). Conclusion The ASKp showed no clear advantages compared to KPS/PSS even though economical and patients' effort was higher. Further application range may be limited through ceiling effects. Both should be taken into consideration. Therefore, the results may not support the usage of ASKp after HSCT and rather suggest KPS/PSS, both patient and clinician reported.}, language = {en} } @misc{HaufNiedingSeger2021, author = {Hauf, Juliane E.

Trait emotional intelligence (EI) may provide a protective shield against the debilitating effects of maladaptive coping thus contributing to maintained HRQoL. Low trait EI, on the other hand, may predispose individuals to apply maladaptive coping, consequently resulting in lower HRQoL. The current research is comprised of two studies. Study 1 was designed to investigate the protective effects of trait EI and its utility for efficient coping in dealing with the stress caused by chronic heart failure (CHF) in a cross-cultural setting (Pakistan vs Germany). N = 200 CHF patients were recruited at cardiology institutes of Multan, Pakistan and W{\"u}rzburg as well as Brandenburg, Germany. Path analysis confirmed the expected relation between low trait EI and low HRQoL and revealed that this association was mediated by maladaptive metacognitions and negative coping strategies in Pakistani but not German CHF patients. Interestingly, also the specific coping strategies were culture-specific. The Pakistani sample considered religious coping to be highly important, whereas the German sample was focused on adopting a healthy lifestyle such as doing exercise. These findings are in line with cultural characteristics suggesting that German CHF patients have an internal locus of control as compared to an external locus of control in Pakistani CHF patients. Finally, the findings from study 1 corroborate the culture-independent validity of the metacognitive model of generalized anxiety disorder. In addition to low trait EI, high interoception accuracy (IA) may predispose individuals to interpret cardiac symptoms as threatening, thus leading to anxiety. To examine this proposition, Study 2 compared individuals with high vs low IA in dealing with a psychosocial stressor (public speaking) in an experimental lab study. In addition, a novel physiological intervention named transcutaneous vagus nerve stimulation (t-VNS) and cognitive reappraisal (CR) were applied during and after the anticipation of the speech in order to facilitate coping with stress. N= 99 healthy volunteers participated in the study. Results showed interesting descriptive results that only reached trend level. They suggested a tendency of high IA individuals to perceive the situation as more threatening as indicated by increased heart rate and reduced heart rate variability in the high-frequency spectrum as well as high subjective anxiety during anticipation of and actual performance of the speech. This suggests a potential vulnerability of high IA individuals for developing anxiety disorders, specifically social anxiety disorder, in case negative self-focused attention and negative evaluation is applied to the (more prominently perceived) increased cardiac responding during anticipation of and the actual presentation of the public speech. The study did not reveal any significant protective effects of t-VNS and CR. In summary, the current research suggested that low trait EI and high IA predicted worse psychological adjustment to chronic and acute distress. Low trait EI facilitated maladaptive metacognitive processes resulting in the use of negative coping strategies in Study 1; however, increased IA regarding cardioceptions predicted high physiological arousal in study 2. Finally, the German vs. the Pakistani culture greatly affected the preference for specific coping strategies. These findings have implications for caregivers to provide culture-specific treatments on the one hand. On the other hand, they highlight high IA as a possible vulnerability to be targeted for the prevention of (social) anxiety.}, subject = {Deutschland}, language = {en} } @phdthesis{Tibken2020, author = {Tibken, Catharina Maria}, title = {Die Entwicklung phonologischer Bewusstheit im Vorschulalter - Institutionelle Einfl{\"u}sse und wechselseitige Zusammenh{\"a}nge mit phonologischen, fr{\"u}hen schriftsprachlichen und sprachlichen Kompetenzen}, doi = {10.25972/OPUS-20805}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-208056}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2020}, abstract = {Phonologische Bewusstheit stellt die Kompetenz dar, Sprache in kleinere Einheiten wie einzelne Silben und Phoneme untergliedern zu k{\"o}nnen.

Da die Tests zur Erfassung der phonologischen Bewusstheit im weiteren Sinne (auf Reim- und Silbenebene) Deckeneffekte aufwiesen und sich im Vorschulalter insbesondere die phonologische Bewusstheit im engeren Sinne (auf Phonemebene) entwickelt, wurde das latente Konstrukt der phonologischen Bewusstheit im Weiteren ausschließlich durch Messverfahren zur Erfassung der phonologischen Bewusstheit im engeren Sinne modelliert.

Technological progress has brought overwhelming opportunities for learners, but challenges them at the same time. Learners have to regulate their learning process to a much greater extent than in traditional learning situations in which teachers support them through external regulation. This means that learners must plan their learning process themselves, apply appropriate learning strategies, monitor, control and evaluate it. These requirements are taken into account in various models of self-regulated learning (SRL). Although the roots of research on SRL go back to the 1980s, the measurement and adequate support of SRL in technology-enhanced learning environments is still not solved in a satisfactory way. An important obstacle are the data sources used to operationalize SRL processes. In order to support SRL in adaptive learning systems and to validate theoretical models, instruments are needed which meet the classical quality criteria and also fulfil additional requirements. Suitable data channels must be measurable "online", i.e., they must be available in real time during learning for analyses or the individual adaptation of interventions. Researchers no longer only have an interest in the final results of questionnaires or tasks, but also need to examine process data from interactions between learners and learning environments in order to advance the development of theories and interventions. In addition, data sources should not be obtrusive so that the learning process is not interrupted or disturbed. Measurements of physiological data, for example, require learners to wear measuring devices. Moreover, measurements should not be reactive. This means that other variables such as learning outcomes should not be influenced by the measurement. Different data sources that are already used to study and support SRL processes, such as protocols on thinking aloud, screen recording, eye tracking, log files, video observations or physiological sensors, meet these criteria to varying degrees. One data channel that has received little attention in research on educational psychology, but is non-obtrusive, non-reactive, objective and available online, is the detailed, timely high-resolution data on observable interactions of learners in online learning environments. This data channel is introduced in this thesis as "peripheral data". It records both the content of learning environments as context, and related actions of learners triggered by mouse and keyboard, as well as the reactions of learning environments, such as structural or content changes. Although the above criteria for the use of the data are met, it is unclear whether this data can be interpreted reliably and validly with regard to relevant variables and behavior. Therefore, the aim of this dissertation is to examine this data channel from the perspective of SRL and thus further close the existing research gap.

Although, in general, the beneficial effects of story interventions have been demonstrated (Marulis \& Neuman, 2010, 2013), many factors possibly moderating those effects - including method of story delivery as well as questioning style - merit further examination (R. L. Walsh \& Hodge, 2018). The aim of the present doctoral thesis was to test predictions from different theories on methods of story delivery and questioning styles regarding their influence on children's vocabulary learning from listening to stories. Method of story delivery refers to the general way of how stories can be conveyed, with reading aloud and free-telling of stories (i.e., the narrator telling stories without reading from text) representing different approaches that are assumed to differ regarding narrator behavior and linguistic complexity. Questioning styles refer to different combinations of questions' cognitive demand level (low vs. high vs. scaffolding-like increasing from low to high) and/or placement (within the story vs. after the story) during story sessions. In the present doctoral thesis, the first two studies (Studies 1 and 2) compared reading aloud and free-telling of stories as different methods of story delivery. Study 1 consisted of two experiments utilizing a within-subjects design with 3- to 6-year-old preschool children (Nexperiment1 = 83; Nexperiment2 = 48) listening to stories once either presented read aloud or freely told. Study 2 extended the first study by examining effects on story comprehension and additionally including audiotape versions of both story-delivery methods as experimental conditions, which allowed separating narrator behavior and linguistic complexity. With the second study being conducted as a between-subjects design, 4- to 6-year-old preschool children (N = 60) heard each of the stories twice, but listened only to one type of story delivery. The results of Study 1 indicated that no differences between methods of story delivery regarding word learning and child engagement were observable when narrator behavior in terms of eye contact and gesticulation was similar. However in Study 2, when free-telling was operationalized in a more naturalistic way, marked by higher rates of eye contact and gesticulation, it resulted in better child engagement, greater vocabulary learning, and better story comprehension than reading aloud. In contrast, as indicated by both studies, differences in linguistic complexity had no short-term impact on learning and comprehension. The studies, however, could not isolate the influence of eye contact versus gesture usage and could not distinguish between different types of gestures. The second set of studies (Studies 3 and 4) contrasted the effects of different types of question demand level (low vs. high vs. scaffolding-like increasing from low to high) and placement (within the story vs. after the story) and examined potential interactions with children's cognitive skills. In one-to-one reading sessions (Study 3; N = 86) or small-group reading sessions (Study 4; N = 91) 4- to 6-year-old preschool children heard stories three times marked by different types of question demand level and placement or simply read-aloud without questions. The adult narrators encouraged the children to reflect on and answer questions (Study 1) and to give feedback on other children's comments (Study 2), but in both studies, to ensure fidelity of the experimental conditions, the adult narrators did not provide corrective feedback or elaborate on the children's answers. Results on measures of different facets of word learning indicated that asking questions resulted in better vocabulary learning than simply reading the stories aloud. However, in contrast to proposed hypotheses and across both studies, different types of question demand level and placement did not exert differential effects and they did not interact with children's general vocabulary knowledge or memory skills. Thus, both studies suggest that those two types of questions features have no impact on children's vocabulary learning, if questions are not followed up by narrator feedback and elaborations. However, whether different types of question placement and demand level produce differential learning gains through adult-child discussion following different questioning styles has still to be determined. Taken together, the four studies of the present doctoral thesis underline the central role that adults play for successful story sessions with young children not only for engaging children in the story but also for extending and for correcting their utterances. Although the presented studies extend existing knowledge about methods of story delivery and questioning styles during story sessions, further research needs to examine the impact of questioning styles on word learning through subsequent adult-child discussion and to gain a better understanding of the role of nonverbal narrator behavior during story delivery.}, subject = {Sprachf{\"o}rderung}, language = {en} } @phdthesis{Genheimer2020, author = {Genheimer, Hannah}, title = {The acquisition of anxiety and the impact of transcutaneous vagus nerve stimulation on extinction learning in virtual contexts}, doi = {10.25972/OPUS-20639}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-206390}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2020}, abstract = {This thesis aims for a better understanding of the mechanisms underlying anxiety as well as trauma- and stressor-related disorders and the development of new therapeutic approaches. I was first interested in the associative learning mechanisms involved in the etiology of anxiety disorders. Second, I explored the therapeutic effects of transcutaneous vagus nerve stimulation (tVNS) as a promising new method to accelerate and stabilize extinction learning in humans. For these purposes, I applied differential anxiety conditioning protocols realized by the implementation of virtual reality (VR). Here, a formerly neutral virtual context (anxiety context, CTX+) is presented whereby the participants unpredictably receive mildly aversive electric stimuli (unconditioned stimulus, US). Another virtual context (safety context, CTX-) is never associated with the US. Moreover, extinction of conditioned anxiety can be modeled by presenting the same contexts without US delivery. When unannounced USs were administered after extinction, i.e. reinstatement, the strength of the "returned" conditioned anxiety can provide information on the stability of the extinction memory. In Study 1, I disentangled the role of elemental and conjunctive context representations in the acquisition of conditioned anxiety. Sequential screenshots of two virtual offices were presented like a flip-book so that I elicited the impression of walking through the contexts. Some pictures of CTX+ were paired with an US (threat elements), but not some other screenshots of the same context (non-threat elements), nor the screenshots depicting CTX- (safety elements). Higher contingency ratings for threat compared to non-threat elements revealed elemental representation. Electro-cortical responses showed larger P100 and early posterior negativity amplitudes elicited by screenshots depicting CTX+ compared to CTX- and suggested conjunctive representation. These results support the dual context representation in anxiety acquisition in healthy individuals. Study 2 addressed the effects of tVNS on the stabilization of extinction learning by using a context conditioning paradigm. Potentiated startle responses as well as higher aversive ratings in CTX+ compared to CTX- indicate successful anxiety conditioning. Complete extinction was found in startle responses and valence ratings as no differentiation between CTX+ and CTX- suggested. TVNS did not affect extinction or reinstatement of anxiety which may be related to the inappropriate transferability of successful stimulation parameters from epilepsy patients to healthy participants during anxiety extinction. Therefore, in Study 3 I wanted to replicate the modulatory effects of tVNS on heart rate and pain perception by the previously used parameters. However, no effects of tVNS were observed on subjective pain ratings, on pain tolerance, or on heart rate. This led to the conclusion that the modification of stimulation parameters is necessary for a successful acceleration of anxiety extinction in humans. In Study 4, I prolonged the tVNS and, considering previous tVNS studies, I applied a cue conditioning paradigm in VR. Therefore, during acquisition a cue (CS+) presented in CTX+ predicted the US, but not another cue (CS-). Both cues were presented in a second context (CTX-) and never paired with the US. Afterward, participants received either tVNS or sham stimulation and underwent extinction learning. I found context-dependent cue conditioning only in valence ratings, which was indicated by lower valence for CS+ compared to CS- in CTX+, but no differential ratings in CTX-. Successful extinction was indicated by equal responses to CS+ and CS-. Interestingly, I found reinstatement of conditioned fear in a context-dependent manner, meaning startle response was potentiated for CS+ compared to CS- only in the anxiety context. Importantly, even the prolonged tVNS had no effect, neither on extinction nor on reinstatement of context-dependent cue conditioning. However, I found first evidence for accelerated physiological contextual extinction due to less differentiation between startles in CTX+ compared to CTX- in the tVNS than in the sham stimulated group. In sum, this thesis first confirms the dual representation of a context in an elemental and a conjunctive manner. Second, though anxiety conditioning and context-dependent cue conditioning paradigms worked well, the translation of tVNS accelerated extinction from rats to humans needs to be further developed, especially the stimulation parameters. Nevertheless, tVNS remains a very promising approach of memory enhancement, which can be particularly auspicious in clinical settings.}, subject = {Angst}, language = {en} } @phdthesis{Ahrens2020, author = {Ahrens, Lea Marlen}, title = {The Role of Attentional Control and Fear Acquisition and Generalization in Social Anxiety Disorder}, doi = {10.25972/OPUS-17162}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-171622}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2020}, abstract = {Although Social Anxiety Disorder (SAD) is one of the most prevalent mental disorders, still little is known about its development and maintenance. Cognitive models assume that deviations in attentional as well as associative learning processes play a role in the etiology of SAD. Amongst others, deficits in inhibitory attentional control as well as aberrations during fear generalization, which have already been observed in other anxiety disorders, are two candidate mechanisms that might contribute to the onset and retention of SAD. However, a review of the literature shows that there is a lack of research relating to these topics. Thus, the aim of the present thesis was to examine in which way individuals with SAD differ from healthy controls regarding attentional control and generalization of acquired fear during the processing of social stimuli. Study 1 tested whether impairment in the inhibitory control of attention is a feature of SAD, and how it might be influenced by emotional expression and gaze direction of an interactional partner. For this purpose, individuals with SAD and healthy controls (HC) participated in an antisaccade task with faces displaying different emotional expressions (angry, neutral and happy) and gaze directions (direct and averted) serving as target stimuli. While the participants performed either pro- or antisaccades in response to the peripherally presented faces, their gaze behavior was recorded via eye-tracking, and ratings of valence and arousal were obtained. Results revealed that both groups showed prolonged latencies and increased error rates in trials with correct anti- compared to prosaccades. However, there were no differences between groups with regard to response latency or error rates, indicating that SAD patients did not exhibit impairment on inhibitory attentional control in comparison to HC during eye-tracking. Possible explanations for this finding could be that reduced inhibitory attentional control in SAD only occurs under certain circumstances, for example, when these individuals currently run the risk of being negatively evaluated by others and not in the mere presence of phobic stimuli, or when the cognitive load of a task is so high that it cannot be unwound by compensatory strategies, such as putting more effort into a task. As not only deviations in attentional, but also associative learning processes might be pathogenic markers of SAD, these mechanisms were further addressed in the following experiments. Study 2 is the first that attempted to investigate the generalization of conditioned fear in patients with SAD. To this end, patients with SAD and HC were conditioned to two neutral female faces serving as conditioned stimuli (CS+: reinforced; CS-: non-reinforced) and a fearful face paired with a loud scream serving as unconditioned stimulus (US). Fear generalization was tested by presenting morphs of the two faces (GS: generalization stimuli), which varied in their similarity to the original faces. During the whole experiment, self-report ratings, heart rate (HR) and skin conductance responses (SCR) were recorded. Results demonstrated that SAD patients rated all stimuli as less pleasant and more arousing, and overestimated the occurrence of the US compared to HC, indicating a general hyperarousal in individuals with SAD. In addition, ratings and SCR indicated that both groups generalized their acquired fear from the CS+ to intermediate GSs as a function of their similarity to the CS+. However, except for the HR data, which indicated that only SAD patients but not HC displayed a generalization response in this measure, most of the results did not support the hypothesis that SAD is characterized by overgeneralization. A plausible reason for this finding could be that overgeneralization is just a key characteristic of some anxiety disorders and SAD is not one of them. Still, other factors, such as comorbidities in the individuals with SAD, could also have had an influence on the results, which is why overgeneralization was further examined in study 3. The aim of study 3 was to investigate fear generalization on a neuronal level. Hence, high (HSA) and low socially anxious participants (LSA) underwent a conditioning paradigm, which was an adaption of the experimental design used study 2 for EEG. During the experiment, steady-state visually evoked potentials (ssVEPs) and ratings of valence and arousal were recorded. Analyses revealed significant generalization gradients in all ratings with highest fear responses to the CS+ and a progressive decline of these reactions with increasing similarity to the CS-. In contrast, the generalization gradient on a neuronal level showed highest amplitudes for the CS+ and a reduction in amplitude to the most proximal, but not distal GSs in the ssVEP signal, which might be interpreted as lateral inhibition in the visual cortex. The observed dissociation among explicit and implicit measures points to different functions of behavioral and sensory cortical processes during fear generalization: While the ratings might reflect an individual's consciously increased readiness to react to threat, the lateral inhibition pattern in the occipital cortex might serve to maximize the contrast among stimuli with and without affective value and thereby improve adaptive behavior. As no group differences could be observed, the finding of study 2 that overgeneralization does not seem to be a marker of SAD is further consolidated. In sum, the conducted experiments suggest that individuals with SAD are characterized by a general hyperarousal during the exposition to disorder-relevant stimuli as indicated by enhanced arousal and reduced valence ratings of the stimuli compared to HC. However, the hypotheses that reduced inhibitory attentional control and overgeneralization of conditioned fear are markers of SAD were mostly not confirmed. Further research is required to elucidate whether they only occur under certain circumstances, such as high cognitive load (e.g. handling two tasks simultaneously) or social stress (e.g. before giving a speech), or whether they are not characteristics of SAD at all. With the help of these findings, new interventions for the treatment of SAD can be developed, such as attentional bias modification or discrimination learning.}, subject = {Sozialangst}, language = {en} } @phdthesis{LangeneSoehnchen2020, author = {Lange [n{\´e} S{\"o}hnchen], Bastian}, title = {Influence of social anxiety on social attention and corresponding changes in action patterns}, doi = {10.25972/OPUS-18900}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-189001}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2020}, abstract = {People who suffer Social Anxiety Disorder (SAD) are under substantial personal distress and endure impaired normal functioning in at least some parts of everyday life. Next, to the personal suffering, there are also the immense public health costs to consider, as SAD is the most common anxiety disorder and thereby one of the major psychiatric disorders in general. Over the last years, fundamental research found cognitive factors as essential components in the development and maintenance of social fears. Following leading cognitive models, avoidance behaviors are thought to be an important factor in maintaining the developed social anxieties. Therefore, this thesis aims to deepen the knowledge of avoidance behaviors exhibited in social anxiety, which allows to get a better understanding of how SAD is maintained. To reach this goal three studies were conducted, each using a different research approach. In the first study cutting-edge Virtual Reality (VR) equipment was used to immerse participants in a virtual environment. In this virtual setting, High Socially Anxious (HSA) individuals and matched controls had to execute a social Approach-Avoidance Task (AAT). In the task, participants had to pass a virtual person displaying neutral or angry facial expressions. By using a highly immersive VR apparatus, the first described study took the initial step in establishing a new VR task for the implicit research on social approach-avoidance behaviors. By moving freely through a VR environment, participants experienced near real-life social situations. By tracking body and head movements, physical and attentional approach-avoidance processes were studied. The second study looked at differences in attention shifts initiated by gaze-cues of neutral or emotional faces. Comparing HSA and controls, enabled a closer look at attention re-allocation with special focus on social stimuli. Further, context conditioning was used to compare task performance in a safe and in a threatening environment. Next to behavioral performance, the study also investigated neural activity using Electroencephalography (EEG) primarily looking at the N2pc component. In the third study, eye movements of HSA and Low Socially Anxious (LSA) were analyzed using an eye-tracking apparatus while participants executed a computer task. The participants' tasks consisted of the detection of either social or non-social stimuli in complex visual settings. The study intended to compare attention shifts towards social components between these two tasks and how high levels of social anxiety influence them. In other words, the measurements of eye movements enabled the investigation to what extent social attention is task-dependent and how it is influenced by social anxiety. With the three described studies, three different approaches were used to get an in-depth understanding of what avoidance behaviors in SAD are and to which extent they are exhibited. Overall, the results showed that HSA individuals exhibited exaggerated physical and attentional avoidance behavior. Furthermore, the results highlighted that the task profoundly influences attention allocation. Finally, all evidence indicates that avoidance behaviors in SAD are exceedingly complex. They are not merely based on the fear of a particular stimulus, but rather involve highly compound cognitive processes, which surpass the simple avoidance of threatening stimuli. To conclude, it is essential that further research is conducted with special focus on SAD, its maintaining factors, and the influence of the chosen research task and method.}, subject = {Sozialangst}, language = {en} } @phdthesis{Wiedemann2020, author = {Wiedemann, Katharina}, title = {Fr{\"u}hzeitige Informationen {\"u}ber Systemgrenzen beim hochautomatisierten Fahren}, doi = {10.25972/OPUS-21658}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-216581}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2020}, abstract = {Fahrzeughersteller haben die Verf{\"u}gbarkeit sogenannter hochautomatisierter Fahrfunktionen (SAE Level 3; SAE, 2018) in ihren Modellen angek{\"u}ndigt.

Das {\"U}bernahmeerfordernis wird dem Fahrer durch die Ausgabe einer {\"U}bernameaufforderung vermittelt. Die {\"U}bernahme der manuellen Fahrzeugf{\"u}hrung aus dem hochautomatisierten Fahren stellt aus psychologischer Sicht einen Aufgabenwechsel dar. Bei der Untersuchung von Aufgabenwechseln im Bereich der kognitiven und angewandten Psychologie zeigte sich vielfach, dass Aufgabenwechsel mit verl{\"a}ngerten Reaktionszeiten und erh{\"o}hten Fehlerraten assoziiert sind. F{\"u}r den Anwendungsfall des automatisierten Fahrens liegen ebenfalls eine Reihe empirischer Studien vor, die darauf hinweisen, dass der Wechsel zum manuellen Fahren mit einer Verschlechterung der Fahrleistung gegen{\"u}ber dem manuellen Fahren verbunden ist.

Das zweite Experiment befasste sich mit der Frage, wie solche Ank{\"u}ndigungen zeitlich und inhaltlich zu gestalten sind (d. h. wann sie pr{\"a}sentiert werden und welche Informationen sie enthalten sollten), und welchen Einfluss deren Gestaltung auf die Aufgabenbearbeitung (insbesondere deren Unterbrechung und sp{\"a}tere Wiederaufnahme) w{\"a}hrend der automatisierten Fahrt hat. Um herauszufinden, wie ein Anzeigekonzept zur l{\"a}ngerfristigen Planung von fahrfremden T{\"a}tigkeiten w{\"a}hrend des automatisierten Fahrens beitragen k{\"o}nnte, fand im dritten Experiment ein Vergleich von Situationsank{\"u}ndigungen, die vor dem Erreichen einer {\"U}bernahmesituation ausgegeben wurden, mit kontinuierlich pr{\"a}sentierten Informationen {\"u}ber die verbleibende Distanz zur n{\"a}chsten Systemgrenze statt. In allen Studien wurde neben den Auswirkungen fr{\"u}hzeitiger Vorinformationen auf die {\"U}bernahmeleistung und Bearbeitung von fahrfremden T{\"a}tigkeiten auch untersucht, welche Auswirkungen ein erweitertes {\"U}bernahmekonzept auf die Fahrerreaktion in Grenz- und Fehlerf{\"a}llen, in denen Vorinformationen entweder nicht oder fehlerhaft angezeigt wurden, hat.

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.}, language = {en} } @article{DuekingTaflerWallmannSperlichetal.2020, author = {D{\"u}king, Peter and Tafler, Marie and Wallmann-Sperlich, Birgit and Sperlich, Billy and Kleih, Sonja}, title = {Behavior Change Techniques in Wrist-Worn Wearables to Promote Physical Activity: Content Analysis}, series = {JMIR Mhealth and Uhealth}, volume = {8}, journal = {JMIR Mhealth and Uhealth}, number = {11}, doi = {10.2196/20820}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-230556}, year = {2020}, abstract = {Background: Decreasing levels of physical activity (PA) increase the incidences of noncommunicable diseases, obesity, and mortality. 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 V{\´i}voactive 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 V{\´i}voactive 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.}, language = {en} } @phdthesis{Menne2020, author = {Menne, Isabelle M.}, title = {Facing Social Robots - Emotional Reactions towards Social Robots}, edition = {1.

Roboter bekommen milit{\"a}rische Bef{\"o}rderungen, Beerdigungen und Ehrenmedaillen (Garreau, 2007; Carpenter, 2013). Ein Schildkr{\"o}tenroboter wird entwickelt, um Kindern beizubringen, Roboter gut zu behandeln (Ackermann, 2018). Der humanoide Roboter Sophia wurde erst k{\"u}rzlich Saudi-Arabischer Staatsb{\"u}rger und es gibt bereits Debatten, ob Roboter Rechte bekommen sollen (Delcker, 2018). Diese und {\"a}hnliche Entwicklungen zeigen schon jetzt die Bedeutsamkeit von Robotern und die emotionale Wirkung die diese ausl{\"o}sen. Dennoch scheinen sich diese emotionalen Reaktionen auf einer anderen Ebene abzuspielen, gemessen an Kommentaren in Internetforen. Dort ist oftmals die Rede davon, wieso jemand {\"u}berhaupt emotional auf einen Roboter reagieren kann. Tats{\"a}chlich ist es, rein rational gesehen, schwierig zu erkl{\"a}ren, warum Menschen mit einer leblosen (‚mindless') Maschine mitf{\"u}hlen sollten. Und dennoch zeugen nicht nur oben genannte Berichte, sondern auch erste wissenschaftliche Studien (z.B. Rosenthal- von der P{\"u}tten et al., 2013) von dem emotionalen Einfluss den Roboter auf Menschen haben k{\"o}nnen. Trotz der Bedeutsamkeit der Erforschung emotionaler Reaktionen auf Roboter existieren bislang wenige wissenschaftliche Studien hierzu. Tats{\"a}chlich identifizierten Kappas, Krumhuber und K{\"u}ster (2013) die systematische Analyse und Evaluation sozialer Reaktionen auf Roboter als eine der gr{\"o}ßten Herausforderungen der affektiven Mensch-Roboter Interaktion. Nach Scherer (2001; 2005) bestehen Emotionen aus der Koordination und Synchronisation verschiedener Komponenten, die miteinander verkn{\"u}pft sind. Motorischer Ausdruck (Mimik), subjektives Erleben, Handlungstendenzen, physiologische und kognitive Komponenten geh{\"o}ren hierzu. Um eine Emotion vollst{\"a}ndig zu erfassen, m{\"u}ssten all diese Komponenten gemessen werden, jedoch wurde eine solch umfassende Analyse bisher noch nie durchgef{\"u}hrt (Scherer, 2005). Haupts{\"a}chlich werden Frageb{\"o}gen eingesetzt (vgl. Bethel \& Murphy, 2010), die allerdings meist nur das subjektive Erleben abfragen. Bakeman und Gottman (1997) geben sogar an, dass nur etwa 8\% der psychologischen Forschung auf Verhaltensdaten basiert, obwohl die Psychologie traditionell als das ‚Studium von Psyche und Verhalten' (American Psychological Association, 2018) definiert wird. Die Messung anderer Emotionskomponenten ist selten. Zudem sind Frageb{\"o}gen mit einer Reihe von Nachteilen behaftet (Austin, Deary, Gibson, McGregor, Dent, 1998; Fan et al., 2006; Wilcox, 2011). Bethel und Murphy (2010) als auch Arkin und Moshkina (2015) pl{\"a}dieren f{\"u}r einen Multi-Methodenansatz um ein umfassenderes Verst{\"a}ndnis von affektiven Prozessen in der Mensch-Roboter Interaktion zu erlangen. Das Hauptziel der vorliegenden Dissertation ist es daher, mithilfe eines Multi-Methodenansatzes verschiedene Komponenten von Emotionen (motorischer Ausdruck, subjektive Gef{\"u}hlskomponente, Handlungstendenzen) zu erfassen und so zu einem vollst{\"a}ndigeren und tiefgreifenderem Bild emotionaler Prozesse auf Roboter beizutragen. Um dieses Ziel zu erreichen, wurden drei experimentelle Studien mit insgesamt 491 Teilnehmern durchgef{\"u}hrt. Mit unterschiedlichen Ebenen der „apparent reality" (Frijda, 2007) sowie Macht / Kontrolle {\"u}ber die Situation (vgl. Scherer \& Ellgring, 2007) wurde untersucht, inwiefern sich Intensit{\"a}t und Qualit{\"a}t emotionaler Reaktionen auf Roboter {\"a}ndern und welche weiteren Faktoren (Aussehen des Roboters, emotionale Expressivit{\"a}t des Roboters, Behandlung des Roboters, Autorit{\"a}tsstatus des Roboters) Einfluss aus{\"u}ben. Experiment 1 basierte auf Videos, die verschiedene Arten von Robotern (tier{\"a}hnlich, anthropomorph, maschinenartig), die entweder emotional expressiv waren oder nicht (an / aus) in verschiedenen Situationen (freundliche Behandlung des Roboters vs. Misshandlung) zeigten. Frageb{\"o}gen {\"u}ber selbstberichtete Gef{\"u}hle und die motorisch-expressive Komponente von Emotionen: Mimik (vgl. Scherer, 2005) wurden analysiert. Das Facial Action Coding System (Ekman, Friesen, \& Hager, 2002), die umfassendste und am weitesten verbreitete Methode zur objektiven Untersuchung von Mimik, wurde hierf{\"u}r verwendet. Die Ergebnisse zeigten, dass die Probanden Gesichtsausdr{\"u}cke (Action Unit [AU] 12 und AUs, die mit positiven Emotionen assoziiert sind, sowie AU 4 und AUs, die mit negativen Emotionen assoziiert sind) sowie selbstberichtete Gef{\"u}hle in {\"U}bereinstimmung mit der Valenz der in den Videos gezeigten Behandlung zeigten. Bei emotional expressiven Robotern konnten st{\"a}rkere emotionale Reaktionen beobachtet werden als bei nicht-expressiven Robotern. Der tier{\"a}hnliche Roboter Pleo erfuhr in der Misshandlungs-Bedingung am meisten Mitleid, Empathie, negative Gef{\"u}hle und Traurigkeit, gefolgt vom anthropomorphen Roboter Reeti und am wenigsten f{\"u}r den maschinenartigen Roboter Roomba. Roomba wurde am meisten Antipathie zugeschrieben. Die Ergebnisse kn{\"u}pfen an fr{\"u}here Forschungen an (z.B. Krach et al., 2008; Menne \& Schwab, 2018; Riek et al., 2009; Rosenthal-von der P{\"u}tten et al., 2013) und zeigen das Potenzial der Mimik f{\"u}r eine nat{\"u}rliche Mensch-Roboter Interaktion. Experiment 2 und Experiment 3 {\"u}bertrugen die klassischen Experimente von Milgram (1963; 1974) zum Thema Gehorsam in den Kontext der Mensch-Roboter Interaktion. Die Gehorsamkeitsstudien von Milgram wurden als sehr geeignet erachtet, um das Ausmaß der Empathie gegen{\"u}ber einem Roboter im Verh{\"a}ltnis zum Gehorsam gegen{\"u}ber einem Roboter zu untersuchen. Experiment 2 unterschied sich von Experiment 3 in der Ebene der „apparent reality" (Frijda, 2007): in Anlehnung an Milgram (1963) wurde eine rein text-basierte Studie (Experiment 2) einer live Mensch-Roboter Interaktion (Experiment 3) gegen{\"u}bergestellt. W{\"a}hrend die abh{\"a}ngigen Variablen von Experiment 2 aus den Selbstberichten emotionaler Gef{\"u}hle sowie Einsch{\"a}tzungen des hypothetischen Verhaltens bestand, erfasste Experiment 3 subjektive Gef{\"u}hle sowie reales Verhalten (Reaktionszeit: Dauer des Z{\"o}gerns; Gehorsamkeitsrate; Anzahl der Proteste; Mimik) der Teilnehmer. Beide Experimente untersuchten den Einfluss der Faktoren „Autorit{\"a}tsstatus" (hoch / niedrig) des Roboters, der die Befehle erteilt (Nao) und die emotionale Expressivit{\"a}t (an / aus) des Roboters, der die Strafen erh{\"a}lt (Pleo). Die subjektiven Gef{\"u}hle der Teilnehmer aus Experiment 2 unterschieden sich zwischen den Gruppen nicht. Dar{\"u}ber hinaus gaben nur wenige Teilnehmer (20.2\%) an, dass sie den „Opfer"-Roboter definitiv bestrafen w{\"u}rden. Ein {\"a}hnliches Ergebnis fand auch Milgram (1963). Das reale Verhalten von Versuchsteilnehmern in Milgrams' Labor-Experiment unterschied sich jedoch von Einsch{\"a}tzungen hypothetischen Verhaltens von Teilnehmern, denen Milgram das Experiment nur beschrieben hatte. Ebenso lassen Kommentare von Teilnehmern aus Experiment 2 darauf schließen, dass das beschriebene Szenario m{\"o}glicherweise als fiktiv eingestuft wurde und Einsch{\"a}tzungen von hypothetischem Verhalten daher kein realistisches Bild realen Verhaltens gegen{\"u}ber Roboter in einer live Interaktion zeichnen k{\"o}nnen. Daher wurde ein weiteres Experiment (Experiment 3) mit einer Live Interaktion mit einem Roboter als Autorit{\"a}tsfigur (hoher Autorit{\"a}tsstatus vs. niedriger) und einem weiteren Roboter als „Opfer" (emotional expressiv vs. nicht expressiv) durchgef{\"u}hrt. Es wurden Gruppenunterschiede in Frageb{\"o}gen {\"u}ber emotionale Reaktionen gefunden. Dem emotional expressiven Roboter wurde mehr Empathie entgegengebracht und es wurde mehr Freude und weniger Antipathie berichtet als gegen{\"u}ber einem nicht-expressiven Roboter. Außerdem konnten Gesichtsausdr{\"u}cke beobachtet werden, die mit negativen Emotionen assoziiert sind w{\"a}hrend Probanden Nao's Befehl ausf{\"u}hrten und Pleo bestraften. Obwohl Probanden tendenziell l{\"a}nger z{\"o}gerten, wenn sie einen emotional expressiven Roboter bestrafen sollten und der Befehl von einem Roboter mit niedrigem Autorit{\"a}tsstatus kam, wurde dieser Unterschied nicht signifikant. Zudem waren alle bis auf einen Probanden gehorsam und bestraften Pleo, wie vom Nao Roboter befohlen. Dieses Ergebnis steht in starkem Gegensatz zu dem selbstberichteten hypothetischen Verhalten der Teilnehmer aus Experiment 2 und unterst{\"u}tzt die Annahme, dass die Einsch{\"a}tzungen von hypothetischem Verhalten in einem Mensch-Roboter-Gehorsamkeitsszenario nicht zuverl{\"a}ssig sind f{\"u}r echtes Verhalten in einer live Mensch-Roboter Interaktion. Situative Variablen, wie z.B. der Gehorsam gegen{\"u}ber Autorit{\"a}ten, sogar gegen{\"u}ber einem Roboter, scheinen st{\"a}rker zu sein als Empathie f{\"u}r einen Roboter. Dieser Befund kn{\"u}pft an andere Studien an (z.B. Bartneck \& Hu, 2008; Geiskkovitch et al., 2016; Menne, 2017; Slater et al., 2006), er{\"o}ffnet neue Erkenntnisse zum Einfluss von Robotern, zeigt aber auch auf, dass die Wahl einer Methode um Empathie f{\"u}r einen Roboter zu evozieren eine nicht triviale Angelegenheit ist (vgl. Geiskkovitch et al., 2016; vgl. Milgram, 1965). Insgesamt st{\"u}tzen die Ergebnisse die Annahme, dass die emotionalen Reaktionen auf Roboter tiefgreifend sind und sich sowohl auf der subjektiven Ebene als auch in der motorischen Komponente zeigen. Menschen reagieren emotional auf einen Roboter, der emotional expressiv ist und eher weniger wie eine Maschine aussieht. Sie empfinden Empathie und negative Gef{\"u}hle, wenn ein Roboter misshandelt wird und diese emotionalen Reaktionen spiegeln sich in der Mimik. Dar{\"u}ber hinaus unterscheiden sich die Einsch{\"a}tzungen von Menschen {\"u}ber ihr eigenes hypothetisches Verhalten von ihrem tats{\"a}chlichen Verhalten, weshalb videobasierte oder live Interaktionen zur Analyse realer Verhaltensreaktionen empfohlen wird.

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).

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.

However, it was shown that punishment is related to trait anger instead of trait altruism in a third-party dictator game if compensation is also available. 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. }, language = {en} } @article{WeissRodriguesPaeleckeetal.2020, author = {Weiß, Martin and Rodrigues, Johannes and Paelecke, Marko and Hewig, Johannes}, title = {We, Them, and It: Dictator Game Offers Depend on Hierarchical Social Status, Artificial Intelligence, and Social Dominance}, series = {Frontiers in Psychology}, volume = {11}, journal = {Frontiers in Psychology}, issn = {1664-1078}, doi = {10.3389/fpsyg.2020.541756}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-218168}, year = {2020}, abstract = {We investigated the influence of social status on behavior in a modified dictator game (DG).

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.

From time to time, this general preference must yield to dishonest actions, which require an effortful process of overcoming initial honest response activation. This thesis presents three experimental series to elucidate this tug-of-war between honest and dishonest response tendencies in overtly committed instances of lies, thereby joining recent efforts to move from a sheer phenomenological perspective on dishonest responding as being more difficult than honest responding to a precise description of the underlying cognitive processes. The consideration of cognitive theories, empirical evidence, and paradigms from different research fields - dishonesty, cognitive control and sensorimotor stage models of information processing - lay the groundwork for the research questions and methodological approach of this thesis. The experiments pinpoint the underlying conflict of dishonest responding in the central, capacity-limited stage of information processing (Experiments 1 to 4), but they also demonstrate that cognitive control processes (Experiments 5 to 7) and the internalization of false alibis (Experiments 8 to 11) can reduce or even completely eliminate this conflict. The data reveals great flexibility at the cognitive basis of dishonest responding: On the one hand, dishonest responding appears to rely heavily on capacity-limited processes of response selection to overcome honest response tendencies alongside up- and downstream consequences of response activation and monitoring. On the other hand, agents have powerful tools to mitigate these effortful processes through control adaptation and false alibis. These results support and expand current theorizing of the cognitive underpinnings of dishonest responding. Furthermore, they are alerting from an applied perspective on the detection of lies, especially when considering the flexibility of even basic cognitive processes in the face of false alibis. A promising way to move forward from here would be a fine-grained discrimination of response activation, passive decay and active inhibition of honest representations in dishonest responding and the assessment of the adaptiveness of these processes.}, subject = {L{\"u}ge}, language = {en} } @phdthesis{Weiss2020, author = {Weiß, Martin}, title = {The neural principles of behavior modification using socioemotional facial feedback cues in economic decision-making}, doi = {10.25972/OPUS-20865}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-208654}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2020}, abstract = {The present dissertation aims to shed light on different mechanisms of socio-emotional feedback in social decision-making situations. The objective is to evaluate emotional facial expressions as feedback stimuli, i.e., responses of interaction partners to certain social decisions. In addition to human faces, artificial emojis are also examined due to their relevance for modern digital communication. Previous research on the influence of emotional feedback suggests that a person's behavior can be effectively reinforced by rewarding stimuli. In the context of this dissertation, the differences in the feedback processing of human photographs and emojis, but also the evaluation of socially expected versus socially unexpected feedback were examined in detail in four studies. In addition to behavioral data, we used the electroencephalogram (EEG) in all studies to investigate neural correlates of social decision-making and emotional feedback. As the central paradigm, all studies were based on a modified ultimatum game. The game is structured as follows: there is a so-called proposer who holds a specific amount of money (e.g., 10 cents) and offers the responder a certain amount (e.g., 3 cents). The responder then decides whether to accept or reject the offer. In the version of the ultimatum game presented here, different types of proposers are introduced. After the participants have accepted or rejected in the role of the responder, the different proposers react to the participant's decision with specific emotional facial expressions. Different feedback patterns are used for the individual experiments conducted in the course of this dissertation. In the first study, we investigated the influence of emotional feedback on decision-making in the modified version of the ultimatum game. We were able to show that a proposer who responds to the acceptance of an offer with a smiling face achieves more accepted offers overall than a control proposer who responds to both accepted and rejected offers with a neutral facial expression. Consequently, the smile served as a positive reinforcement. Similarly, a sad expression in response to a rejected offer also resulted in higher acceptance rates as compared to the control identity, which could be considered an expression of compassion for that proposer. On a neuronal level, we could show that there are differences between simply looking at negative emotional stimuli (i.e., sad and angry faces) and their appearance as feedback stimuli after rejected offers in the modified ultimatum game. The so-called feedback-related negativity was reduced (i.e., more positive) when negative emotions appeared as feedback from the proposers. We argued that these findings might show that the participants wanted to punish the proposers by rejecting an offer for its unfairness and therefore the negative feedback met their expectations. The altered processing of negative emotional facial expressions in the ultimatum game could therefore indicate that the punishment is interpreted as successful. This includes the expectation that the interaction partner will change his behavior in the future and eventually make fairer offers. In the second study we wanted to show that smiling and sad emojis as feedback stimuli in the modified ultimatum game can also lead to increased acceptance rates. Contrary to our assumptions, this effect could not be observed. At the neural level as well, the findings did not correspond to our assumptions and differed strongly from those of the first study. One finding, however, was that the neural P3 component showed how the use of emojis as feedback stimuli particularly characterizes certain types of proposers. This is supported by the fact that the P3 is increased for the proposer who rewards an acceptance with a smile as well as for the proposer who reacts to rejection with a sad emoji compared to the neutral control proposer. The third study examined the discrepancy between the findings of the first and second study. Accordingly, both humans and emojis representing the different proposers were presented in the ultimatum game. In addition, emojis were selected that showed a higher similarity to known emojis from common messenger services compared to the second study. We were able to replicate that the proposers in the ultimatum game, who reward an acceptance of the offer with a smile, led to an increased acceptance rate compared to the neutral control proposers. This difference is independent of whether the proposers are represented by emojis or human faces. With regard to the neural correlates, we were able to demonstrate that emojis and human faces differ strongly in their neural processing. Emojis showed stronger activation than human faces in the face-processing N170 component, the feedback-related negativity and the P3 component. We concluded that the results of the N170 and feedback-related negativity could indicate a signal for missing social information of emojis compared to faces. The increased P3 amplitude for emojis might imply that emojis appear unexpectedly as reward stimuli in a social decision task compared to human faces. The last study of this project dealt with socially unexpected feedback. In comparison to the first three studies, new proposer identities were implemented. In particular, the focus was on a proposer who reacted to the rejection of an offer unexpectedly with a smile and to the acceptance with a neutral facial expression. According to the results, participants approach this unexpected smile through increased rejection, although it is accompanied by financial loss. In addition, as reported in studies one and three, we were able to show that proposers who respond to the acceptance of an offer with a smiling face and thus meet the expectations of the participants have higher offer acceptance rates than the control proposer. At the neuronal level, especially the feedback from the socially unexpected proposer led to an increased P3 amplitude, which indicates that smiling after rejection is attributed a special subjective importance. The experiments provide new insights into the social influence through emotional feedback and the processing of relevant social cues. Due to the conceptual similarity of the studies, it was possible to differentiate between stable findings and potentially stimulus-dependent deviations, thus creating a well-founded contribution to the current research. Therefore, the novel paradigm presented here, and the knowledge gained from it could also play an important role in the future for clinical questions dealing with limited social competencies.}, subject = {Entscheidungsverhalten}, language = {en} } @phdthesis{Hoffmann2020, author = {Hoffmann, Mareike}, title = {Effector System Prioritization in Multitasking}, doi = {10.25972/OPUS-20108}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-201084}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2020}, abstract = {Multitasking, defined as performing more than one task at a time, typically yields performance decrements, for instance, in processing speed and accuracy. These performance costs are often distributed asymmetrically among the involved tasks. Under suitable conditions, this can be interpreted as a marker for prioritization of one task - the one that suffers less - over the other. One source of such task prioritization is based on the use of different effector systems (e.g., oculomotor system, vocal tract, limbs) and their characteristics. The present work explores such effector system-based task prioritization by examining to which extent associated effector systems determine which task is processed with higher priority in multitasking situations. Thus, three different paradigms are used, namely the simultaneous (stimulus) onset paradigm, the psychological refractory period (PRP) paradigm, and the task switching paradigm. These paradigms invoke situations in which two (in the present studies basic spatial decision) tasks are a) initiated at exactly the same time, b) initiated with a short varying temporal distance (but still temporally overlapping), or c) in which tasks alternate randomly (without temporal overlap). The results allow for three major conclusions: 1. The assumption of effector system-based task prioritization according to an ordinal pattern (oculomotor > pedal > vocal > manual, indicating decreasing prioritization) is supported by the observed data in the simultaneous onset paradigm. This data pattern cannot be explained by a rigid "first come, first served" task scheduling principle. 2. The data from the PRP paradigm confirmed the assumption of vocal-over-manual prioritization and showed that classic PRP effects (as a marker for task order-based prioritization) can be modulated by effector system characteristics. 3. The mere cognitive representation of task sets (that must be held active to switch between them) differing in effector systems without an actual temporal overlap in task processing, however, is not sufficient to elicit the same effector system prioritization phenomena observed for overlapping tasks. In summary, the insights obtained by the present work support the assumptions of parallel central task processing and resource sharing among tasks, as opposed to exclusively serial processing of central processing stages. Moreover, they indicate that effector systems are a crucial factor in multitasking and suggest an integration of corresponding weighting parameters in existing dual-task control frameworks.}, subject = {Mehrfacht{\"a}tigkeit}, language = {en} } @article{EidelKuebler2020, author = {Eidel, Matthias and K{\"u}bler, Andrea}, title = {Wheelchair Control in a Virtual Environment by Healthy Participants Using a P300-BCI Based on Tactile Stimulation: Training Effects and Usability}, series = {Frontiers in Human Neuroscience}, volume = {14}, journal = {Frontiers in Human Neuroscience}, issn = {1662-5161}, doi = {10.3389/fnhum.2020.00265}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-207775}, year = {2020}, abstract = {Tactile stimulation is less frequently used than visual for brain-computer interface (BCI) control, partly because of limitations in speed and accuracy.

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.}, language = {en} } @article{EderMitschkeGollwitzer2020, author = {Eder, Andreas B. and Mitschke, Vanessa and Gollwitzer, Mario}, title = {What stops revenge taking?

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.

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.}, language = {en} } @article{SeitzLenhartRuebsam2020, author = {Seitz, Maximilian and Lenhart, Jan and R{\"u}bsam, Nina}, title = {The effects of gendered information in stories on preschool children's development of gender stereotypes}, series = {British Journal of Developmental Psychology}, volume = {38}, journal = {British Journal of Developmental Psychology}, number = {3}, doi = {10.1111/bjdp.12323}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-214622}, pages = {363 -- 390}, year = {2020}, abstract = {Social-cognitive theory posits that children learn gender stereotypes through gendered information.

VRE was conducted in a driving simulator with a fully equipped mockup. The exposure scenarios were individually tailored to the patients' anxiety hierarchy. A total of 14 patients were treated. Parameters on the verbal, behavioral and physiological level were assessed. Results The treatment was helpful to overcome driving fear and avoidance. In the final BAT, all patients mastered driving tasks they had avoided before, 71\% showed an adequate driving behavior as assessed by the driving instructor, and 93\% could maintain their treatment success until the second follow-up phone call. Further analyses suggest that treatment reduces avoidance behavior as well as symptoms of posttraumatic stress disorder as measured by standardized questionnaires (Avoidance and Fusion Questionnaire: p < .10, PTSD Symptom Scale-Self Report: p < .05).

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.}, language = {en} } @article{PoetzschGermanakosHuestegge2020, author = {Poetzsch, Tristan and Germanakos, Panagiotis and Huestegge, Lynn}, title = {Toward a Taxonomy for Adaptive Data Visualization in Analytics Applications}, series = {Frontiers in Artificial Intelligence}, volume = {3}, journal = {Frontiers in Artificial Intelligence}, issn = {2624-8212}, doi = {10.3389/frai.2020.00009}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-202074}, year = {2020}, abstract = {Data analytics as a field is currently at a crucial point in its development, as a commoditization takes place in the context of increasing amounts of data, more user diversity, and automated analysis solutions, the latter potentially eliminating the need for expert analysts. 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.}, language = {en} } @article{LiesnerKirschPfisteretal.2020, author = {Liesner, Marvin and Kirsch, Wladimir and Pfister, Roland and Kunde, Wilfried}, title = {Spatial action-effect binding depends on type of action-effect transformation}, series = {Attention, Perception, \& Psychophysics}, volume = {82}, journal = {Attention, Perception, \& Psychophysics}, issn = {1943-3921}, doi = {10.3758/s13414-020-02013-2}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-232781}, pages = {2531-2543}, year = {2020}, abstract = {Spatial action-effect binding denotes the mutual attraction between the perceived position of an effector (e.g., one's own hand) and a distal object that is controlled by this effector.

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.}, language = {en} } @article{EndlichRichterMarxetal.2020, author = {Endlich, Darius and Richter, Tobias and Marx, Peter and Lenhard, Wolfgang and Moll, Kristina and Witzel, Bj{\"o}rn and Schulte-K{\"o}rne, Gerd}, title = {Spelling Error Detection : A Valid and Economical Task for Assessing Spelling Skills in Elementary-School Children}, series = {Zeitschrift f{\"u}r Entwicklungspsychologie und P{\"a}dagogische Psychologie}, volume = {52}, journal = {Zeitschrift f{\"u}r Entwicklungspsychologie und P{\"a}dagogische Psychologie}, number = {1-2}, issn = {0049-8637}, doi = {10.1026/0049-8637/a000227}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-244665}, pages = {25-40}, year = {2020}, abstract = {The ability to spell words correctly is a key competence for educational and professional achievement.

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.

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.

Based on general theoretical concepts regarding mental processes it will differentiate between modular, abstract information processing approaches to cognition and interactive, embodied ideas of mental processing. These general concepts will then be transferred to the context of processing voice-related information in the context of parallel face-related processing streams. One central issue here is whether and to what extent cognitive voice processing can occur independently, that is, encapsulated from the simultaneous processing of visual person-related information (and vice versa). In Study 1 (Huestegge \& Raettig, in press), participants are presented with audio-visual stimuli displaying faces uttering digits. Audiovisual gender congruency was manipulated: There were male and female faces, each uttering digits with either a male or female voice (all stimuli were AV- synchronized). Participants were asked to categorize the gender of either the face or the voice by pressing one of two keys in each trial. A central result was that audio-visual gender congruency affected performance: Incongruent stimuli were categorized slower and more error-prone, suggesting a strong cross-modal interaction of the underlying visual and auditory processing routes. Additionally, the effect of incongruent visual information on auditory classification was stronger than the effect of incongruent auditory information on visual categorization, suggesting visual dominance over auditory processing in the context of gender classification. A gender congruency effect was also present under high cognitive load. Study 2 (Huestegge, Raettig, \& Huestegge, in press) utilized the same (gender-congruent and -incongruent) stimuli, but different tasks for the participants, namely categorizing the spoken digits (into odd/even or smaller/larger than 5). This should effectively direct attention away from gender information, which was no longer task-relevant. Nevertheless, congruency effects were still observed in this study. This suggests a relatively automatic processing of cross-modal gender information, which eventually affects basic speech-based information processing. Study 3 (Huestegge, subm.) focused on the ability of participants to match unfamiliar voices to (either static or dynamic) faces. One result was that participants were indeed able to match voices to faces. Moreover, there was no evidence for any performance increase when dynamic (vs. mere static) faces had to be matched to concurrent voices. The results support the idea that common person-related source information affects both vocal and facial features, and implicit corresponding knowledge appears to be used by participants to successfully complete face-voice matching. Taken together, the three studies (Huestegge, subm.; Huestegge \& Raettig, in press; Huestegge et al., in press) provided information to further develop current theories of voice processing (in the context of face processing). On a general level, the results of all three studies are not in line with an abstract, modular view of cognition, but rather lend further support to interactive, embodied accounts of mental processing.}, subject = {Stimme}, language = {en} } @phdthesis{Rubo2019, author = {Rubo, Marius}, title = {Social Attention in the Laboratory, in Real Life and in Virtual Reality}, doi = {10.25972/OPUS-18845}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-188452}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2019}, abstract = {Social attention is a ubiquitous, but also enigmatic and sometimes elusive phenomenon. We direct our gaze at other human beings to see what they are doing and to guess their intentions, but we may also absorb social events en passant as they unfold in the corner of the eye. We use our gaze as a discrete communication channel, sometimes conveying pieces of information which would be difficult to explicate, but we may also find ourselves avoiding eye-contact with others in moments when self-disclosure is fear-laden. We experience our gaze as the most genuine expression of our will, but research also suggests considerable levels of predictability and automaticity in our gaze behavior. The phenomenon's complexity has hindered researchers from developing a unified framework which can conclusively accommodate all of its aspects, or from even agreeing on the most promising research methodologies. The present work follows a multi-methods approach, taking on several aspects of the phenomenon from various directions. Participants in study 1 viewed dynamic social scenes on a computer screen. Here, low-level physical saliency (i.e. color, contrast, or motion) and human heads both attracted gaze to a similar extent, providing a comparison of two vastly different classes of gaze predictors in direct juxtaposition. In study 2, participants with varying degrees of social anxiety walked in a public train station while their eye movements were tracked. With increasing levels of social anxiety, participants showed a relative avoidance of gaze at near compared to distant people. When replicating the experiment in a laboratory situation with a matched participant group, social anxiety did not modulate gaze behavior, fueling the debate around appropriate experimental designs in the field. Study 3 employed virtual reality (VR) to investigate social gaze in a complex and immersive, but still highly controlled situation. In this situation, participants exhibited a gaze behavior which may be more typical for real-life compared to laboratory situations as they avoided gaze contact with a virtual conspecific unless she gazed at them. This study provided important insights into gaze behavior in virtual social situations, helping to better estimate the possible benefits of this new research approach.

What mental processes are involved when people decide not to act to reach certain effects? From the outside it may seem that nothing remarkable is happening, because no action can be observed. However, I present three studies which disclose the cognitive processes that control nonactions. The present experiments address situations where people intentionally decide to omit certain actions in order to produce a predictable effect in the environment. These experiments are based on the ideomotor hypothesis, which suggests that bidirectional associations can be formed between actions and the resulting effects. Because of these associations, anticipating the effects can in turn activate the respective action. The results of the present experiments show that associations can be formed between nonactions (i.e., the intentional decision not to act) and the resulting effects. Due to these associations, perceiving the nonaction effects encourages not acting (Exp. 1-3). What is more, planning a nonaction seems to come with an activation of the effects that inevitably follow the nonaction (Exp. 4-5). These results suggest that the ideomotor hypothesis can be expanded to nonactions and that nonactions are cognitively represented in terms of their sensory effects. Furthermore, nonaction effects can elicit a sense of agency (Exp. 6-8). That is, even though people refrain from acting, the resulting nonaction effects are perceived as self-produced effects. In a nutshell, these findings demonstrate that intentional nonactions include specific mechanisms and processes, which are involved, for instance, in effect anticipation and the sense of agency. This means that, while it may seem that nothing remarkable is happening when people decide not to act, complex processes run on the inside, which are also involved in intentional actions.}, subject = {Intention}, language = {en} } @phdthesis{AdelAbdelrehimMohamedSoliman2019, author = {Adel Abdelrehim Mohamed Soliman, Hadya}, title = {Structural Equation Modeling of Factors Influencing EFL Reading comprehension: Comparative study between Egypt and Germany}, doi = {10.25972/OPUS-18695}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-186957}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2019}, abstract = {In most foreign language learning contexts, there are only rare chance for contact with native speakers of the target language. In such a situation, reading plays an important role in language acquisition as well as in gaining cultural information about the target language and its speakers. Previous research indicated that reading in foreign language is a complex process, which is influenced by various linguistic, cognitive and affective factors. The aim of the present study was to test two structural models of the relationship between reading comprehension in native language (L1), English language (L2) reading motivation, metacognitive awareness of L2 reading strategies, and reading comprehension of English as a foreign language among the two samples. Furthermore, the current study aimed to examine the differences between Egyptian and German students in their perceived usage of reading strategies during reading English texts, as well as to explore the pattern of their motivation toward reading English texts. For this purpose, 401 students were recruited from Germany (n=200) and Egypt (n=201) to participate in the current study. In order to have information about metacognitive awareness of reading strategies, a self-report questionnaire (SORS) developed by Moktari and Sheory (2002) was used. While the L2 reading motivation variable, was measured by a reading motivation survey (L2RMQ) which was based on reviewed reading motivation research. In addition, two reading tests were administrated one to measure reading comprehension for native language (German/Arabic) and the other to measure English reading comprehension. To analyze the collected data, descriptive statistics and independent t-tests were performed. In addition, further analysis using structural equation modeling was applied to test the strength of relationships between the variables under study. The results from the current research revealed that L1 reading comprehension, whether in a German or Arabic language, had the strongest relationship with L2 reading comprehension. However, the relationship between L2 intrinsic reading motivation was not proven to be significant in either the German or Egyptian models. On the other hand, the relationship between L2 extrinsic reading motivation, metacognitive awareness of reading strategies, and L2 reading comprehension was only proven significant in the German sample. The discussion of these results along with their pedagogical implications for education and practice will be illustrated in the following study.}, subject = {Leseverstehen}, language = {en} } @phdthesis{Akakpo2019, author = {Akakpo, Martin Gameli}, title = {The influence of learner characteristics on interactions to seek and share information in e-learning: A media psychology perspective}, doi = {10.25972/OPUS-18593}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-185934}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2019}, abstract = {Research on the deployment and use of technology to assist learning has seen a significant rise over the last decades (Aparicio et al., 2017). The focus on course quality, technology, learning outcome and learner satisfaction in e-learning has led to insufficient attention by researchers to individual characteristics of learners (Cidral et al., 2017 ; Hsu et al., 2013). The current work aims to bridge this gap by investigating characteristics identified by previous works and backed by theory as influential individual differences in e-learning. These learner characteristics have been suggested as motivational factors (Edmunds et al., 2012) in decisions by learners to interact and exchange information (Luo et al., 2017). In this work e-learning is defined as interaction dependent information seeking and sharing enabled by technology. This is primarily approached from a media psychology perspective. The role of learner characteristics namely, beliefs about the source of knowledge (Schommer, 1990), learning styles (Felder \& Silverman, 1988), need for affect (Maio \& Esses, 2001), need for cognition (Cacioppo \& Petty, 1982) and power distance (Hofstede, 1980) on interactions to seek and share information in e-learning are investigated. These investigations were shaped by theory and empirical lessons as briefly mentioned in the next paragraphs. Theoretical support for investigations is derived from the technology acceptance model(TAM) by psychologist Davis (1989) and the hyper-personal model by communication scientist Walther (1996). The TAM was used to describe the influence of learner characteristics on decisions to use e-learning systems (Stantchev et al., 2014). The hyper-personal model described why computer-mediated communication thrives in e-learning (Kaye et al., 2016) and how learners interpret messages exchanged online (Hansen et al., 2015). This theoretical framework was followed by empirical reviews which justified the use of interaction and information seeking-sharing as key components of e-learning as well as the selection of learner characteristics. The reviews provided suggestions for the measurement of variables (K{\"u}hl et al., 2014) and the investigation design (Dascalau et al., 2015). Investigations were designed and implemented through surveys and quasi experiments which were used for three preliminary studies and two main studies. Samples were selected from Germany and Ghana with same variables tested in both countries. Hypotheses were tested with interaction and information seeking-sharing as dependent variables while beliefs about the source of knowledge, learning styles, need for affect, need for cognition and power distance were independent variables. Firstly, using analyses of variance, the influence of beliefs about the source of knowledge on interaction choices of learners was supported. Secondly, the role of need for cognition on interaction choices of learners was supported by results from a logistic regression. Thirdly, results from multiple linear regressions backed the influence of need for cognition and power distance on information seeking-sharing behaviour of learners. Fourthly, the relationship between need for affect and need for cognition was supported. The findings may have implications for media psychology research, theories used in this work, research on e-learning, measurement of learner characteristics and the design of e-learning platforms. The findings suggest that, the beliefs learners have about the source of knowledge, their need for cognition and their power distance can influence decisions to interact and seek or share information. The outlook from reviews and findings in this work predicts more research on learner characteristics and a corresponding intensity in the use of e-learning by individuals. It is suggested that future studies investigate the relationship between learner autonomy and power distance. Studies on inter-cultural similarities amongst e-learners in different populations are also suggested.}, subject = {e-learning}, language = {en} } @phdthesis{Goetz2019, author = {G{\"o}tz, Felix Johannes}, title = {Social Cueing of Numerical Magnitude : Observed Head Orientation Influences Number Processing}, doi = {10.25972/OPUS-18716}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-187161}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2019}, abstract = {In many parts of the modern world, numbers are used as tools to describe spatial relationships, be it heights, latitudes, or distances. However, this connection goes deeper as a myriad of studies showed that number representations are rooted in space (vertical, horizontal, and/or radial). For instance, numbers were shown to affect spatial perception and, conversely, perceptions or movements in space were shown to affect number estimations. This bidirectional link has already found didactic application in the classroom when children are taught the meaning of numbers. However, our knowledge about the cognitive (and neuropsychological) processes underlying the numerical magnitude operations is still very limited. Several authors indicated that the processing within peripersonal space (i.e. the space surrounding the body in reaching distance) and numerical magnitude operations are functionally equivalent. This assumption has several implications that the present work aims at describing. For instance, vision and visuospatial attention orienting play a prominent role for processing within peripersonal space. Indeed, both neuropsychological and behavioral studies also suggested a similar role of vision and visuospatial attention orienting for number processing. Moreover, social cognition research showed that movements, posture and gestures affect not only the representation of one's own peripersonal space, but also the visuospatial attention behavior of an observer. Against this background, the current work tests the specific implication of the functional equivalence assumption that the spatial attention response to an observed person's posture should extend to the observer's numerical magnitude operations. The empirical part of the present work tests the spatial attention response of observers to vertical head postures (with continuing eye contact to the observer) in both perceptual and numerical space. Two experimental series are presented that follow both steps from the observation of another person's vertical head orientation (within his/her peripersonal space) to the observer's attention orienting response (Experimental series A) as well as from there to the observer's magnitude operations with numbers (Experimental Series B). Results show that the observation of a movement from a neutral to a vertical head orientation (Experiment 1) as well as the observation of the vertical head orientation alone (Experiment 3) shifted the observer's spatial attention in correspondence with the direction information of the observed head (up vs. down). Movement from a vertical to a neutral end position, however, had no effect on the observer's spatial attention orienting response (Experiment 2). Furthermore, following down-tilted head posture (relative to up- or non-tilted head orientation), observers generated smaller numbers in a random number generation task (range 1- 9, Experiment 4), gave smaller estimates to numerical trivia questions (mostly multi-digit numbers, Experiment 5) and chose response keys less frequently in a free choice task that was associated with larger numerical magnitude in a intermixed numerical magnitude task. Experimental Series A served as groundwork for Experimental Series B, as it demonstrated that observing another person's head orientation indeed triggered the expected directional attention orienting response in the observer. Based on this preliminary work, the results of Experimental Series B lend support to the assumption that numerical magnitude operations are grounded in visuospatial processing of peripersonal space. Thus, the present studies brought together numerical and social cognition as well as peripersonal space research. Moreover, the Empirical Part of the present work provides the basis for elaborating on the role of processing within peripersonal space in terms of Walsh's (2003, 2013) Theory of Magnitude. In this context, a specification of the Theory of Magnitude was staked out in a processing model that stresses the pivotal role of spatial attention orienting. Implications for mental magnitude operations are discussed. Possible applications in the classroom and beyond are described.}, subject = {Soziale Wahrnehmung}, language = {en} } @phdthesis{Flechsenhar2019, author = {Flechsenhar, Aleya Felicia}, title = {The Ubiquity of Social Attention - a Detailed Investigation of the Underlying Mechanisms}, doi = {10.25972/OPUS-18452}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-184528}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2019}, abstract = {This dissertation highlights various aspects of basic social attention by choosing versatile approaches to disentangle the precise mechanisms underlying the preference to focus on other human beings. The progressive examination of different social processes contrasted with aspects of previously adopted principles of general attention. Recent research investigating eye movements during free exploration revealed a clear and robust social bias, especially for the faces of depicted human beings in a naturalistic scene. However, free viewing implies a combination of mechanisms, namely automatic attention (bottom-up), goal-driven allocation (top-down), or contextual cues and inquires consideration of overt (open exploration using the eyes) as well as covert orienting (peripheral attention without eye movement). Within the scope of this dissertation, all of these aspects have been disentangled in three studies to provide a thorough investigation of different influences on social attention mechanisms. In the first study (section 2.1), we implemented top-down manipulations targeting non-social features in a social scene to test competing resources. Interestingly, attention towards social aspects prevailed, even though this was detrimental to completing the requirements. Furthermore, the tendency of this bias was evident for overall fixation patterns, as well as fixations occurring directly after stimulus onset, suggesting sustained as well as early preferential processing of social features. Although the introduction of tasks generally changes gaze patterns, our results imply only subtle variance when stimuli are social. Concluding, this experiment indicates that attention towards social aspects remains preferential even in light of top-down demands. The second study (section 2.2) comprised of two separate experiments, one in which we investigated reflexive covert attention and another in which we tested reflexive as well as sustained overt attention for images in which a human being was unilaterally located on either the left or right half of the scene. The first experiment consisted of a modified dot-probe paradigm, in which peripheral probes were presented either congruently on the side of the social aspect, or incongruently on the non-social side. This was based on the assumption that social features would act similar to cues in traditional spatial cueing paradigms, thereby facilitating reaction times for probes presented on the social half as opposed to the non-social half. Indeed, results reflected such congruency effect. The second experiment investigated these reflexive mechanisms by monitoring eye movements and specifying the location of saccades and fixations for short as well as long presentation times. Again, we found the majority of initial saccades to be congruently directed to the social side of the stimulus. Furthermore, we replicated findings for sustained attention processes with highest fixation densities for the head region of the displayed human being. The third study (section 2.3), tackled the other mechanism proposed in the attention dichotomy, the bottom-up influence. Specifically, we reduced the available contextual information of a scene by using a gaze-contingent display, in which only the currently fixated regions would be visible to the viewer, while the remaining image would remain masked. Thereby, participants had to voluntarily change their gaze in order to explore the stimulus. First, results revealed a replication of a social bias in free-viewing displays. Second, the preference to select social features was also evident in gaze-contingent displays. Third, we find higher recurrent gaze patterns for social images compared to non-social ones for both viewing modalities. Taken together, these findings imply a top-down driven preference for social features largely independent of contextual information. Importantly, for all experiments, we took saliency predictions of different computational algorithms into consideration to ensure that the observed social bias was not a result of high physical saliency within these areas. For our second experiment, we even reduced the stimulus set to those images, which yielded lower mean and peak saliency for the side of the stimulus containing the social information, while considering algorithms based on low-level features, as well as pre-trained high-level features incorporated in deep learning algorithms. Our experiments offer new insights into single attentional mechanisms with regard to static social naturalistic scenes and enable a further understanding of basic social processing, contrasting from that of non-social attention. The replicability and consistency of our findings across experiments speaks for a robust effect, attributing social attention an exceptional role within the general attention construct, not only behaviorally, but potentially also on a neuronal level and further allowing implications for clinical populations with impaired social functioning.}, subject = {Aufmerksamkeit}, language = {en} }
