The Food Cravings Questionnaires (FCQs) assess food cravings on a trait and a state level. Method: The current study examined half-year retest-reliability of the Food Cravings Questionnaire-Trait-reduced (FCQ-T-r) and the Food Cravings Questionnaire-State (FCQ-S) and reports associations with current food deprivation in female students. Results: The FCQ-T-r had higher retest-reliability (rtt = .74) than the FCQ-S (rtt = .39). Although trait food craving was correlated with state food craving, it was unaffected by current food deprivation. Conclusions: Although state and trait food craving are interdependent, the FCQs are able to differentiate between the two. As scores of the FCQ-T-r represent a stable trait, but are also sensitive to changes in eating behavior, they may be useful for the investigation of the course of eating disorders and obesity.}, language = {en} } @article{SollfrankHartGoodselletal.2015, author = {Sollfrank, Teresa and Hart, Daniel and Goodsell, Rachel and Foster, Jonathan and Tan, Tele}, title = {3D visualization of movements can amplify motor cortex activation during subsequent motor imagery}, series = {Frontiers in Human Neuroscience}, volume = {9}, journal = {Frontiers in Human Neuroscience}, number = {463}, doi = {10.3389/fnhum.2015.00463}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-126058}, year = {2015}, abstract = {A repetitive movement practice by motor imagery (MI) can influence motor cortical excitability in the electroencephalogram (EEG). This study investigated if a realistic visualization in 3D of upper and lower limb movements can amplify motor related potentials during subsequent MI. We hypothesized that a richer sensory visualization might be more effective during instrumental conditioning, resulting in a more pronounced event related desynchronization (ERD) of the upper alpha band (10-12 Hz) over the sensorimotor cortices thereby potentially improving MI based brain-computer interface (BCI) protocols for motor rehabilitation. The results show a strong increase of the characteristic patterns of ERD of the upper alpha band components for left and right limb MI present over the sensorimotor areas in both visualization conditions. Overall, significant differences were observed as a function of visualization modality (VM; 2D vs. 3D). The largest upper alpha band power decrease was obtained during MI after a 3-dimensional visualization. In total in 12 out of 20 tasks the end-user of the 3D visualization group showed an enhanced upper alpha ERD relative to 2D VM group, with statistical significance in nine tasks.With a realistic visualization of the limb movements, we tried to increase motor cortex activation during subsequent MI. The feedback and the feedback environment should be inherently motivating and relevant for the learner and should have an appeal of novelty, real-world relevance or aesthetic value (Ryan and Deci, 2000; Merrill, 2007). Realistic visual feedback, consistent with the participant's MI, might be helpful for accomplishing successful MI and the use of such feedback may assist in making BCI a more natural interface for MI based BCI rehabilitation.}, language = {en} } @article{ZieglerEhlisWeberetal.2021, author = {Ziegler, Georg C. and Ehlis, Ann-Christine and Weber, Heike and Vitale, Maria Rosaria and Z{\"o}ller, Johanna E.

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 half of the trials, this cue was rendered invisible by pattern masking. In both experiments, visible cues led to cueing effects, that is, faster responses after valid compared to invalid cues. Importantly, even masked cues caused cueing effects, though to a lesser extent. Additionally, we analyzed effects on attention that persist from one trial to the subsequent trial. We found that spatial anticipations are able to interfere with newly formed spatial anticipations and influence orienting of attention in the subsequent trial. When the preceding cue was visible, the corresponding spatial anticipation persisted to an extent that prevented a noticeable effect of masked cues. The effects of visible cues were likewise modulated by previous spatial anticipations, but were strong enough to also exert an impact on attention themselves. Altogether, the results suggest that spatial anticipations can be formed on the basis of unconscious stimuli, but that interfering influences like still active spatial anticipations can suppress this effect.}, language = {en} } @article{SeibelVolmer2021, author = {Seibel, Sebastian and Volmer, Judith}, title = {A Diary Study on Anticipated Leisure Time, Morning Recovery, and Employees' Work Engagement}, series = {International Journal of Environmental Research and Public Health}, volume = {18}, journal = {International Journal of Environmental Research and Public Health}, number = {18}, issn = {1660-4601}, doi = {10.3390/ijerph18189436}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-246090}, year = {2021}, abstract = {Recovery during yesterday's leisure time is beneficial for morning recovery, and morning recovery fosters employees' work engagement, a positive, motivational state associated with job performance.

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.

However, safety behavior in anxiety-related disorders is often costly, and persists even the situation does not entail realistic threat. Individuals can engage in safety behavior to varying extents, however, these behaviors are typically measured dichotomously (i.e., to execute or not). To better understand the nuances of safety behavior, this study developed a dimensional measure of safety behavior that had a negative linear relationship with the admission of an aversive outcome. In two experiments, a Reward group receiving fixed or individually calibrated incentives competing with safety behavior showed reduced safety behavior than a Control group receiving no incentives. This allowed extinction learning to a previously learnt warning signal in the Reward group (i.e., updating the belief that this stimulus no longer signals threat). Despite the Reward group exhibited extinction learning, both groups showed a similar increase in fear to the warning signal once safety behavior was no longer available. This null group difference was due to some participants in the Reward group not incentivized enough to disengage from safety behavior. Dimensional assessment revealed a dissociation between low fear but substantial safety behavior to a safety signal in the Control group. This suggests that low-cost safety behavior does not accurately reflect the fear-driven processes, but also other non-fear-driven processes, such as cost (i.e., engage in safety behavior merely because it bears little to no cost). Pinpointing both processes is important for furthering the understanding of safety behavior.}, language = {en} } @phdthesis{Topolinski2009, author = {Topolinski, Sascha}, title = {A fluency-affect intuition model}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-38807}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2009}, abstract = {The present approach highlights a procedural account of intuitive judgments.

Using a single-/dual-response switch paradigm, we analyzed switches between dual ([A + B]) and single ([A], [B]) responses across different effector systems and revealed comparable performance in partial repetitions and full switches of behavioral requirements (e.g., in [A + B] → [A] vs. [B] → [A], or [A] → [A + B] vs. [B] → [A + B]), but only when the presence of dimensional overlap between responses allows for Gestalt formation.

In der psychologischen Forschung unterscheidet man drei Arten der Perspektiven{\"u}bernahme, n{\"a}mlich perzeptuelle (visuo-spatiale), affektive (Empathie) und kognitive (Theory of Mind). Die letztgenannten Arten der Perspektiven{\"u}bernahme werden oft als „psychologische Perspektiven{\"u}bernahme" zusammengefasst. Diese Dissertation befasst sich mit der Frage, ob diese verschiedenen Arten der Perspektiven{\"u}bernahme als theoretisch unterscheidbare Konstrukte oder lediglich als Facetten ein und desselben Konstrukts angesehen werden sollten. Die Befundlage in der psychologischen Fachliteratur ist diesbez{\"u}glich nicht eindeutig. W{\"a}hrend einige Autoren Korrelationen zwischen verschiedenen Arten der Perspektiven{\"u}bernahme f{\"u}r zu gering erachten, um ein einheitliches Konstrukt zu konstatieren, bewerten andere Autoren Korrelationen derselben Gr{\"o}ße als Evidenz hierf{\"u}r. Ein weniger arbitr{\"a}res Vorgehen w{\"a}re es, experimentalpsychologisch zugrunde liegende Mechanismen zu identifizieren, die allen Arten der Perspektiven{\"u}bernahme gemein sind, und zu untersuchen, ob eine Manipulation dieser Mechanismen abh{\"a}ngige Maße affektiver, kognitiver und perzeptueller Perspektiven{\"u}bernahme gleichermaßen beeinflusst. Diesem Ansatz folgend macht die vorliegende Arbeit die Annahme, dass die mentale Selbstrotation des K{\"o}rperschemas in die Position einer anderen Person, der zentrale Mechanismus visuo-spatialer Perspektiven{\"u}bernahme, ein gemeinsamer Mechanismus aller Arten der Perspektiven{\"u}bernahme ist. Entgegen fr{\"u}herer Ans{\"a}tze wird diese Einheit somit nicht nur {\"u}ber die zentrale gemeinsame Funktionalit{\"a}t aller Arten von Perspektiven{\"u}bernahme, also dem Verlassen des egozentrischen Referenzrahmens zugunsten einer (visuellen, affektiven oder kognitiven) Fremdperspektive, gerechtfertigt, sondern mit der Annahme eines gemeinsamen zugrundeliegenden Mechanismus. Daraus wird die einfache Hypothese abgeleitet, dass visuo-spatiale Perspektiven{\"u}bernahme zu psychologischen Konsequenzen f{\"u}hren kann. Dies wurde in 6 Experimenten getestet. In diesen Experimenten mussten die Probanden zun{\"a}chst immer die visuelle Perspektive einer anderen Person einnehmen. Hierzu sahen die Probanden eine Person, die mit zwei Objekten an einem Tisch sitzt. In jedem Durchgang mussten die Probanden sich entscheiden, mit welcher Hand diese Person eines der beiden Objekte greifen w{\"u}rde. Dabei wurde die Position der Zielperson so manipuliert, dass sie in der H{\"a}lfte der F{\"a}lle im selben visuo-spatialen Referenzrahmen wie der Proband saß, was Perspektiven{\"u}bernahme zur L{\"o}sung der Aufgabe obsolet machte, w{\"a}hrend sie sich in den verbleibenden Durchg{\"a}ngen in einem anderen visuo-spatialen Referenzrahmen befand, so dass die Probanden die visuelle Perspektive der Zielperson {\"u}bernehmen mussten um die Aufgabe korrekt zu l{\"o}sen. Nach jedem Durchgang wurde dem Ziel dieser visuo-spatialen Aufgabe eine psychologische Eigenschaft zugeschrieben. Dies geschah im Rahmen eines abgewandelten Paradigmas zur Untersuchung der Ankerheuristik. Hierzu wurde den Probanden nach jedem Durchgang der visuo-spatialen Aufgabe eine Sch{\"a}tzfrage gestellt. Zeitgleich wurde die Antwort des Ziels bekannt gegeben. Entsprechend der Haupthypothese, dass visuo-spatiale Perspektiven{\"u}bernahme psychologische Konsequenzen erzeugen kann, konnte gezeigt werden, dass die Probanden nach visuo-spatialer Perspektiven{\"u}bernahme in h{\"o}herem Maße die Gedanken der Zielperson {\"u}bernahmen. Dies konnte sowohl anhand der absoluten Gr{\"o}ße des Ankereffekts, als auch anhand der Differenz zwischen den Urteilen der Probanden und der Zielperson, gezeigt werden.

Such behavior can be assessed with the open field test (OFT), which is a well-established indicator of animal fear. The detection of similar open field behavior in humans may verify the translational validity of this paradigm. Enhanced thigmotaxis related to anxiety may suggest the relevance of such behavior for anxiety disorders, especially agoraphobia. METHODS: A global positioning system was used to analyze the behavior of 16 patients with agoraphobia and 18 healthy individuals with a risk for agoraphobia (i.e., high anxiety sensitivity) during a human OFT and compare it with appropriate control groups (n = 16 and n = 19). We also tracked 17 patients with agoraphobia and 17 control participants during a city walk that involved walking through an open market square. RESULTS: Our human OFT triggered thigmotaxis in participants; patients with agoraphobia and participants with high anxiety sensitivity exhibited enhanced thigmotaxis. This behavior was evident in increased movement lengths along the wall of the natural open field and fewer entries into the center of the field despite normal movement speed and length. Furthermore, participants avoided passing through the market square during the city walk, indicating again that thigmotaxis is related to agoraphobia. CONCLUSIONS: This study is the first to our knowledge to verify the translational validity of the OFT and to reveal that thigmotaxis, an evolutionarily adaptive behavior shown by most species, is related to agoraphobia, a pathologic fear of open spaces, and anxiety sensitivity, a risk factor for agoraphobia.}, language = {en} } @article{KaethnerHalderHintermuelleretal.2017, author = {K{\"a}thner, Ivo and Halder, Sebastian and Hinterm{\"u}ller, Christoph and Espinosa, Arnau and Guger, Christoph and Miralles, Felip and Vargiu, Eloisa and Dauwalder, Stefan and Rafael-Palou, Xavier and Sol{\`a}, Marc and Daly, Jean M. and Armstrong, Elaine and Martin, Suzanne and K{\"u}bler, Andrea}, title = {A Multifunctional Brain-Computer Interface Intended for Home Use: An Evaluation with Healthy Participants and Potential End Users with Dry and Gel-Based Electrodes}, series = {Frontiers in Neuroscience}, volume = {11}, journal = {Frontiers in Neuroscience}, number = {286}, doi = {10.3389/fnins.2017.00286}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-157925}, year = {2017}, abstract = {Current brain-computer interface (BCIs) software is often tailored to the needs of scientists and technicians and therefore complex to allow for versatile use.

Furthermore, a new methodological approach to gather and link data about the consumption of psychoactive substances and the mobility of drug users is shown. Traditionally, roadside surveys are conducted to estimate the prevalence of drug driving within a population. By the present study, an alternative method is introduced. In total, 195 drug users (mainly cannabis users) and 100 controls out of the normal driving population were queried for four weeks about their driving and drug consumption behaviour by a questionnaire that was deployed on smartphones. The prevalences of drug driving within the sample were extrapolated into representative values. Because the subjects reported all daily activities within the study-period, it was also possible to describe situations in which the subjects decided against driving under influence. Besides, relevant previous experiences, attitudes, the approval of legal regulations, other traffic-specific parameters, social influences and personality variables were queried. So, individual factors that are associated with drug driving can be specified. The results are integrated in a model that shows dependencies of different societal, behavioural and legal variables. They can serve as major input to the discussion on drug driving and can be of practical use for rehabilitation and prevention purposes. The results can be summarised as follows: - Compared to the results of a German roadside survey from 1994, the prevalences that are found within the present study seem pretty low. This finding is discussed and possible explanations for the described trend are lined out. Furthermore, the prevalences that were calculated in the present study are compared to current data from other European countries. - The results show differences between users and controls on several variables. The differences indicate that substance use impacts on the structuring of day-to-day life. Overall, the controls' days proceed more along a daily working routine than the users' (e.g. less mobility at night, more mobility at rush-hour, alcohol consumption mainly at nights out). - The individual extent to which drugs are consumed differs dependent on daytime, day of the week and kind of substance. Of course, these dependencies also influence the occurrence of drug driving. Other factors of influence on drug driving are the distance, the availability of alternative modes of transport as well as the presence of female companions. - Not everybody who uses drugs drives under the influence of drugs. A striking predictor for frequent drug driving and highly intoxicated driving is a high consumption, associated with risky consumption patterns and a low subjective feeling of impairment after drug consumption. - The subjects' attitudes towards drug driving and their beliefs about social norms largely go in line with the behaviour they engage in. Drug users have rather liberal attitudes towards drug use and driving under influence. - A possible deterrence effect of sanctioning and police enforcement and its dependence on the acceptance and awareness of the measures is delineated. - Only small effects are found when examining the objective impairment that is caused by drug use by a computer-based test battery. This result is critically discussed with regards to the operationalisation of the study groups. - Except from driving under influence, there is no evidence to suggest that DUI offenders also show problematic behaviour according to other traffic-related measures. - Parents and peers may have an influence as role models on the development of problematic behaviour. A good relationship between parents and children may have a positive impact on the development of conventional values and behaviour. - Drug use is associated with some crucial personality dimensions and drugs are often used to solve personal problems. A less precise but similar difference was found for users who commit many drives under influence compared to users who never or only sometimes drive under influence. Moreover, users marginally more often have psychological problems compared to controls. Finally, the strengths and weaknesses of the new methodological approach of data collection are discussed as well as the challenges that are faced when implementing it. All in all, it has proved to be a promising method and should serve as a standard to which future studies should aspire.}, subject = {Verkehrspsychologie}, language = {en} } @article{ConzelmannReifJacobetal.2012, author = {Conzelmann, Annette and Reif, Andreas and Jacob, Christian and Weyers, Peter and Lesch, Klaus-Peter and Lutz, Beat and Pauli, Paul}, title = {A polymorphism in the gene of the endocannabinoid-degrading enzyme FAAH (FAAH C385A) is associated with emotional-motivational reactivity}, series = {Psychopharmacology}, volume = {224}, journal = {Psychopharmacology}, number = {4}, doi = {10.1007/s00213-012-2785-y}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-126845}, pages = {573-579}, year = {2012}, abstract = {RATIONALE: The endocannabinoid (eCB) system is implicated in several psychiatric disorders. Investigating emotional-motivational dysfunctions as underlying mechanisms, a study in humans revealed that in the C385A polymorphism of the fatty acid amide hydrolase (FAAH), the degrading enzyme of the eCB anandamide (AEA), A carriers, who are characterized by increased signaling of AEA as compared to C/C carriers, exhibited reduced brain reactivity towards unpleasant faces and enhanced reactivity towards reward. However, the association of eCB system with emotional-motivational reactivity is complex and bidirectional due to upcoming compensatory processes. OBJECTIVES: Therefore, we further investigated the relationship of the FAAH polymorphism and emotional-motivational reactivity in humans. METHODS: We assessed the affect-modulated startle, and ratings of valence and arousal in response to higher arousing pleasant, neutral, and unpleasant pictures in 67 FAAH C385A C/C carriers and 45 A carriers. RESULTS: Contrarily to the previous functional MRI study, A carriers compared to C/C carriers exhibited an increased startle potentiation and therefore emotional responsiveness towards unpleasant picture stimuli and reduced startle inhibition indicating reduced emotional reactivity in response to pleasant pictures, while both groups did not differ in ratings of arousal and valence. CONCLUSIONS: Our findings emphasize the bidirectionality and thorough examination of the eCB system's impact on emotional reactivity as a central endophenotype underlying various psychiatric disorders.}, language = {en} } @article{BreilKanskePittigetal.2021, author = {Breil, Christina and Kanske, Philipp and Pittig, Roxana and B{\"o}ckler, Anne}, title = {A revised instrument for the assessment of empathy and Theory of Mind in adolescents: Introducing the EmpaToM-Y}, series = {Behavior Research Methods}, volume = {53}, journal = {Behavior Research Methods}, doi = {10.3758/s13428-021-01589-3}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-302877}, pages = {2487-2501}, year = {2021}, abstract = {Empathy and Theory of Mind (ToM) are two core components of social understanding.

As the EmpaToM has been designed for the assessment of social understanding in adults, it has a high degree of complexity and comprises topics that are inadequate for minors. For this reason, we designed a new version of the EmpaToM that is especially suited to measure empathy and ToM in youths. In experiment 1, we successfully validated the EmpaToM-Y on the original EmpaToM in an adult sample (N = 61), revealing a similar pattern of results across tasks and strong correlations of all constructs. As intended, the performance measure for ToM and the control condition of the EmpaToM-Y showed reduced difficulty. In experiment 2, we tested the feasibility of the EmpaToM-Y in a group of teenagers (N = 36). Results indicate a reliable empathy induction and higher demands of ToM questions for adolescents.

Scores on the FCQ-T have been found to be positively associated with eating pathology, body mass index (BMI), low dieting success and increases in state food craving during cognitive tasks involving appealing food stimuli. The current studies evaluated reliability and validity of a reduced version of the FCQ-T consisting of 15 items only (FCQ-T-r). Study 1 was a questionnaire study conducted online among students (N = 323). In study 2, female students (N = 70) performed a working memory task involving food and neutral pictures. Study 1 indicated a one-factorial structure and high internal consistency (α = 0.94) of the FCQ-T-r. Scores of the FCQ-T-r were positively correlated with BMI and negatively correlated with dieting success. In study 2, participants reported higher state food craving after the task compared to before. This increase was positively correlated with the FCQ-T-r. Hours since the last meal positively predicted food craving before the task when controlling for FCQ-T-r scores and the interaction of both variables. Contrarily, FCQ-T-r scores positively predicted food craving after the task when controlling for food deprivation and the interaction term. Thus, trait food craving was specifically associated with state food craving triggered by palatable food-cues, but not with state food craving related to plain hunger. Results indicate high reliability of the FCQ-T-r. Replicating studies that used the long version, small-to-medium correlations with BMI and dieting success could be found. Finally, scores on the FCQ-T-r predicted cue-elicited food craving, providing further support of its validity. The FCQ-T-r constitutes a succinct, valid and reliable self-report measure to efficiently assess experiences of food craving as a trait.}, language = {en} } @article{KiserGromerPaulietal.2022, author = {Kiser, Dominik P. and Gromer, Daniel and Pauli, Paul and Hilger, Kirsten}, title = {A virtual reality social conditioned place preference paradigm for humans: Does trait social anxiety affect approach and avoidance of virtual agents?}, series = {Frontiers in Virtual Reality}, volume = {3}, journal = {Frontiers in Virtual Reality}, issn = {2673-4192}, doi = {10.3389/frvir.2022.916575}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-293564}, year = {2022}, abstract = {Approach and avoidance of positive and negative social cues are fundamental to prevent isolation and ensure survival. High trait social anxiety is characterized by an avoidance of social situations and extensive avoidance is a risk factor for the development of social anxiety disorder (SAD). Therefore, experimental methods to assess social avoidance behavior in humans are essential. The social conditioned place preference (SCPP) paradigm is a well-established experimental paradigm in animal research that is used to objectively investigate social approach-avoidance mechanisms. We retranslated this paradigm for human research using virtual reality. To this end, 58 healthy adults were exposed to either a happy- or angry-looking virtual agent in a specific room, and the effects of this encounter on dwell time as well as evaluation of this room in a later test without an agent were examined. We did not observe a general SCPP effect on dwell time or ratings but discovered a moderation by trait social anxiety, in which participants with higher trait social anxiety spent less time in the room in which the angry agent was present before, suggesting that higher levels of trait social anxiety foster conditioned social avoidance. However, further studies are needed to verify this observation and substantiate an association with social anxiety disorder. We discussed the strengths, limitations, and technical implications of our paradigm for future investigations to more comprehensively understand the mechanisms involved in social anxiety and facilitate the development of new personalized treatment approaches by using virtual reality.}, language = {en} } @inproceedings{OPUS4-31720, title = {Abstracts of the Wuertual Reality XR Meeting 2023}, editor = {Neumann, Isabel and Gado, Sabrina and K{\"a}thner, Ivo and Hildebrandt, Lea and Andreatta, Marta}, edition = {korrigierte Auflage}, doi = {10.25972/OPUS-31720}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-317203}, pages = {76}, year = {2023}, abstract = {The Wuertual Reality XR Meeting 2023 was initiated to bring together researchers from many fields who use VR/AR/XR.

Moreover, studies so far often lack a suitable control condition, focus on behavioral pain measures rather than physiological correlates, and often use between-subject designs, which potentially impede the evaluation of the effectiveness of the strategies. Therefore, we investigated whether acceptance-based strategies can reduce subjective and physiological markers of acute pain in comparison to a control condition in a within-subject design. To this end, participants (N = 30) completed 24 trials comprising 10 s of heat pain stimulation. Each trial started with a cue instructing participants to welcome and experience pain (acceptance trials) or to react to the pain as it is without employing any regulation strategies (control trials). In addition to pain intensity and unpleasantness ratings, heart rate (HR) and skin conductance (SC) were recorded. Results showed significantly decreased pain intensity and unpleasantness ratings for acceptance compared to control trials. Additionally, HR was significantly lower during acceptance compared to control trials, whereas SC revealed no significant differences. These results demonstrate the effectiveness of acceptance-based strategies in reducing subjective and physiological pain responses relative to a control condition, even after short training.

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} } @phdthesis{Baur2016, author = {Baur, Ramona}, title = {Adult Attention-Deficit/Hyperactivity Disorder (ADHD), Emotion Processing, and Emotion Regulation in Virtual Reality}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-142064}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2016}, abstract = {Attention-Deficit/Hyperactivity Disorder (ADHD) is characterized by symptoms of inattentiveness and hyperactivity/impulsivity. Besides, increasing evidence points to ADHD patients showing emotional dysfunctions and concomitant problems in social life. However, systematic research on emotional dysfunctions in ADHD is still rare, and to date most studies lack conceptual differentiation between emotion processing and emotion regulation. The aim of this thesis was to systematically investigate emotion processing and emotion regulation in adult ADHD in a virtual reality paradigm implementing social interaction. Emotional reactions were assessed on experiential, physiological, and behavioral levels. Experiment 1 was conducted to develop a virtual penalty kicking paradigm implying social feedback and to test it in a healthy sample. This paradigm should then be applied in ADHD patients later on. Pleasant and unpleasant trials in this paradigm consisted of hits respectively misses and subsequent feedback from a virtual coach. In neutral trials, participants were teleported to different spots of the virtual stadium. Results indicated increased positive affectivity (higher valence and arousal ratings, higher zygomaticus activations, and higher expression rates of positive emotional behavior) in response to pleasant compared to neutral trials. Reactions to unpleasant trials were contradictory, indicating increased levels of both positive and negative affectivity, compared to neutral trials. Unpleasant vs. neutral trials revealed lower valence ratings, higher arousal ratings, higher zygomaticus activations, slightly lower corrugator activations, and higher expression rates of both positive and negative emotional behavior. The intensity of emotional reactions correlated with experienced presence in the virtual reality. To better understand the impact of hits or misses per se vs. hits or misses with coach feedback healthy participants' emotional reactions, only 50\% of all shots were followed by coach feedback in experiment 2. Neutral trials consisted of shots over the free soccer field which were followed by coach feedback in 50 \% of all trials. Shots and feedback evoked more extreme valence and arousal ratings, higher zygomaticus activations, lower corrugator activations, and higher skin conductance responses than shots alone across emotional conditions. Again, results speak for the induction of positive emotions in pleasant trials whereas the induction of negative emotions in unpleasant trials seems ambiguous. Technical improvements of the virtual reality were reflected in higher presence ratings than in experiment 1. Experiment 3 investigated emotional reactions of adult ADHD patients and healthy controls after emotion processing and response-focused emotion regulation. Participants successively went through an ostensible online ball-tossing game (cyber ball) inducing negative emotions, and an adapted version of the virtual penalty kicking game. Throughout cyber ball, participants were included or ostracized by two other players in different experimental blocks. Participants were instructed to explicitly show, not regulate, or hide their emotions in different experimental blocks. Results provided some evidence for deficient processing of positive emotions in ADHD. Patients reported slightly lower positive affect than controls during cyber ball, gave lower valence ratings than controls in response to pleasant penalty kicking trials, and showed lower zygomaticus activations than controls especially during penalty kicking. Patients in comparison with controls showed slightly increased processing of unpleasant events during cyber ball (higher ratings of negative affect, especially in response to ostracism), but not during penalty kicking. Patients showed lower baseline skin conductance levels than controls, and impaired skin conductance modulations. Compared to controls, patients showed slight over-expression of positive as well as negative emotional behavior. Emotion regulation analyses revealed no major difficulties of ADHD vs. controls in altering their emotional reactions through deliberate response modulation. Moreover, patients reported to habitually apply adaptive emotion regulation strategies even more frequently than controls. The analyses of genetic high-risk vs. low-risk groups for ADHD across the whole sample revealed similar results as analyses for patients vs. controls for zygomaticus modulations during emotion processing, and for modulations of emotional reactions due to emotion regulation. To sum up, the virtual penalty kicking paradigm proved to be successful for the induction of positive, but not negative emotions. The importance of presence in virtual reality for the intensity of induced emotions could be replicated. ADHD patients showed impaired processing of primarily positive emotions. Aberrations in negative emotional responding were less clear and need further investigation. Results point to adult ADHD in comparison to healthy controls suffering from baseline deficits in autonomic arousal and deficits in arousal modulation.

Over the last decades, the question of whether prosociality undergoes changes over the adult lifespan has gained increased research attention. Earlier studies suggested increased prosociality in older compared to younger individuals. However, recent meta-analyses revealed that this age effect might be heterogeneous and modest. Moreover, the contributing factors and mechanisms behind these age-related variations remain to be identified. To unravel age-related differences in prosociality, the first study of this dissertation employed a meta-analytical approach to summarize existing findings and provide insight into their heterogeneity by exploring linear and quadratic age effects on self-reported and behavioral prosociality. Additionally, two empirical research studies investigated whether these age-related differences in prosociality were observed in real life, assessed through ecological momentary assessment (Study 2), and in a controlled laboratory setting by applying a modified dictator game (Study 3). Throughout these three studies, potential underlying behavioral and computational mechanisms were explored. The outcome of the meta-analysis (Study 1) revealed small linear age effects on prosociality and significant age group differences between younger and older adults, with higher levels of prosociality in older adults. Explorative evidence emerged in favor of a quadratic age effect on behavioral prosociality, indicating the highest levels in midlife. Additionally, heightened prosocial behavior among middle-aged adults was observed compared to younger adults, whereas no significant differences in prosocial behavior were noted between middle-aged and older adults. Situational and contextual features, such as the setting of the study and specific paradigm characteristics, moderated the age-prosociality relationship, highlighting the importance of the (social) context when studying prosociality. For Study 2, no significant age effect on real-life prosocial behavior was observed. However, evidence for a significant linear and quadratic age effect on experiencing empathy in real life emerged, indicating a midlife peak. Additionally, across all age groups, the link between an opportunity to empathize and age significantly predicted real-life prosocial behavior. This effect, indicating higher levels of prosocial behavior when there was a situation possibly evoking empathy, was most pronounced in midlife. Study 3 presented age differences in how older and younger adults integrate values related to monetary gains for self and others to make a potential prosocial decision. Younger individuals effectively combined both values in a multiplicative fashion, enhancing decision-making efficiency. Older adults showed an additive effect of values for self and other and displayed increased decision-making efficiency when considering the values separately. However, among older adults, individuals with better inhibitory control were better able to integrate information about both values in their decisions. Taken together, the findings of this dissertation offer new insights into the multi-faceted nature of prosociality across adulthood and the mechanisms that help explain these age-related disparities. While this dissertation observed increasing prosociality across the adult lifespan, it also questions the assumption that older adults are inherently more prosocial. The studies highlight midlife as a potential peak period in social development but also emphasize the importance of the (social) context and that different operationalizations might capture distinct facets of prosociality. This underpins the need for a comprehensive framework to understand age effects of prosociality better and guide potential interventions.}, subject = {Altersunterschied}, language = {en} } @article{RabinowitzOrnsteinFoldsBennettetal.1994, author = {Rabinowitz, Mitchell and Ornstein, Peter A. and Folds-Bennett, Trisha H. and Schneider, Wolfgang}, title = {Age-related differences in speed of processing: Unconfounding age and experience}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-62223}, year = {1994}, abstract = {No abstract available}, subject = {Psychologie}, language = {en} } @phdthesis{JagiellowiczKaufmann2016, author = {Jagiellowicz-Kaufmann, Monika Sarah}, title = {Akzeptable und effektive Pedal- und Motorkennlinien zur Unterst{\"u}tzung von Eco-Driving im Elektrofahrzeug}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-137031}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2016}, abstract = {Die begrenzte Reichweite ist einer der Hauptgr{\"u}nde f{\"u}r das derzeitige mangelnde Kaufinteresse an Elektrofahrzeugen. Neben rein komponentenoptimierenden Maßnahmen, wie der Verbesserung der Batterie, ist die F{\"o}rderung von Eco-Driving, also einer energieeffizienten Fahrweise, ein effektiver Ansatz zur Steigerung der Reichweite. Trainings und visuell dargebotene Eco-Assistenten k{\"o}nnen Eco-Driving wirksam steigern, sch{\"o}pfen aber nicht dessen gesamtes Potential aus. Angepasste Pedal- und Motorkennlinien k{\"o}nnten Eco-Driving zus{\"a}tzlich f{\"o}rdern. F{\"u}r deren Bewertung sind die Wirksamkeit und Akzeptanz bisher nicht gemeinsam ber{\"u}cksichtig worden oder sie wurden nicht im Elektrofahrzeug evaluiert und validiert. Zu diesen Anpassungen z{\"a}hlen eine Ver{\"a}nderung des Beschleunigungspedals, sodass mit diesem gleichzeitig beschleunigt und rekuperiert werden kann, die Limitierung von Drehmoment und Leistung und der Einsatz eines aktiven Beschleunigungspedals, welches Widerst{\"a}nde abh{\"a}ngig von Fahrzeug- oder Situationsparametern aktiviert. F{\"u}r diese Arbeit habe ich daher die Pedal- und Motorkennlinien entsprechend angepasst und in ein validiertes Elektroautomodell implementiert. Ziel war es, verschiedene Fahrverhaltensbereiche im Elektrofahrzeug, die Eco-Driving kennzeichnen (energieoptimales Beschleunigen und Verz{\"o}gern, Einhalten von Geschwindigkeitsbegrenzungen, vorausschauendes Fahren), benutzerfreundlich, akzeptabel und wirksam zu unterst{\"u}tzen. Zu diesem Zweck habe ich vier Probandenstudien im bewegten Fahrsimulator durchgef{\"u}hrt und geeignete Pedal- und Motorkennlinien empirisch bestimmt. In der ersten Studie habe ich untersucht, ob und warum eine Pedalkennlinie zu bevorzugen ist, bei der mit dem Beschleunigungspedal anstelle des Bremspedals rekuperiert wird. Das Ziel der zweiten Studie war es, eine geeignete Rekuperationsst{\"a}rke f{\"u}r ein kombiniertes Beschleunigungspedal, bei dem mit dem Beschleunigungspedal rekuperiert wird, zu bestimmen. In der dritten Studie habe ich evaluiert, ob die Limitierung der Leistung oder die des Drehmoments zu bevorzugen ist, um das Beschleunigungsverhalten zu optimieren und wie stark die Limitierungen optimaler Weise sein sollten. Basierend auf den Ergebnissen der dritten Studie, habe ich schließlich einen optimierten Limitierungsansatz konzipiert, diesen mit einem aktiven Beschleunigungspedal verglichen und bestimmt, welcher Ansatz zu bevorzugen ist. Aufgrund der Studienergebnisse werden folgende Ans{\"a}tze f{\"u}r die jeweiligen Eco-Driving-Fahrverhaltensbereiche empfohlen und es werden folgende Gestaltungsempfehlungen abgeleitet: Zur F{\"o}rderung eines energieeffizienten Beschleunigungsverhaltens ist die Limitierung von Drehmoment und Leistung geeignet. Die Limitierung des Drehmoments ist hierbei besonders wirksam in geringen, die Limitierung der maximalen Leistung in h{\"o}heren Geschwindigkeitsbereichen. Zu empfehlen sind parallele mittelstarke Limitierungen von maximalem Drehmoment und maximaler Leistung, die Beschleunigungen mit 2.0 m/s² erlauben, bei gleichzeitiger Bereitstellung eines Kick-Downs. Ein aktives Beschleunigungspedal ist insbesondere aus Gr{\"u}nden der Benutzerfreundlichkeit zur F{\"o}rderung eines energieeffizienten Beschleunigungsverhaltens nur eingeschr{\"a}nkt empfehlenswert. Zur F{\"o}rderung eines energieeffizienten Verz{\"o}gerungsverhaltens wird die Implementierung der Rekuperationsfunktion auf dem Beschleunigungspedal anstelle des Bremspedals empfohlen, da dies einerseits erm{\"o}glicht, auf hydraulisches Bremsen zu verzichten und gleichzeitig mehr Energie rekuperiert werden kann. Ersteres tr{\"a}gt zu einer hohen Akzeptanz bei, letzteres zu einer g{\"u}nstigen Energiebilanz. Besonders effektiv und akzeptabel ist ein kombiniertes Fahrbremspedal, wenn es eine starke Rekuperation erm{\"o}glicht (zwischen -1.7 und -2.1 m/s²). Weiterhin ist ein aktives Beschleunigungspedal, das den geeigneten Zeitpunkt f{\"u}r eine maximal energieeffiziente Verz{\"o}gerung mit einem kombinierten Fahrbremspedal anzeigt, wirksam, um die rekuperierte Energie zu steigern. Auf diese Weise kann zudem eine vorausschauende Fahrweise unterst{\"u}tzt werden. Hierbei muss jedoch die Funktionalit{\"a}t und Benutzerfreundlichkeit optimiert werden, um eine gesteigerte kognitive Fahrerbeanspruchung und Minderungen der Akzeptanz zu vermeiden. Zur Unterst{\"u}tzung der Einhaltung von Geschwindigkeitsbegrenzungen ist ebenfalls das aktive Beschleunigungspedal geeignet. Der Fahrer sollte hierbei aber die M{\"o}glichkeit haben, individuell Grenzwerte einzustellen. Die Verkn{\"u}pfung eines kombinierten Fahrbremspedals mit einer Limitierung von Drehmoment und Leistung sowie einem aktiven Beschleunigungspedal kann abschließend, unter Ber{\"u}cksichtigung der abgeleiteten Gestaltungsempfehlungen, als effektive und akzeptable M{\"o}glichkeit zur F{\"o}rderung unterschiedlicher Verhaltensbereiche von Eco-Driving bewertet werden. Die erwarteten Synergieeffekte der evaluierten Ans{\"a}tze in Verbindung mit Eco-Trainings und visuell dargebotenen Eco-Feedback-Assistenten sowie deren Langfristigkeit sollten Gegenstand weiterf{\"u}hrender Forschung sein.}, subject = {Elektrofahrzeug}, language = {de} } @phdthesis{Schnabel2011, author = {Schnabel, Eva}, title = {Alcohol and driving-related performance - A comprehensive meta-analysis focusing the significance of the non-significant}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-69959}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2011}, abstract = {The present work reviews the experimental literature on the acute effects of alcohol on human behaviour related to driving performance. A meta-analysis was conducted which includes studies published between 1954 and 2007 in order to provide a comprehensive knowledge of the substance alcohol. 450 studies reporting 5,300 findings were selected from over 12,000 references after applying certain in- and exclusion criteria. Thus, the present meta-analysis comprises far more studies than reviews on alcohol up to now. In the selected studies, different performance tests were conducted which were relevant for driving. The classification system used in this work assigns these tests to eight categories. The main categories consist of several sub categories classifying the tasks more precisely. The main categories were: (1) visual functions, (2) attention (including vigilance), (3) divided attention, (4) en-/decoding (including information processing and memory), (5) reaction time (including simple reaction time and choice reaction time), (6) psychomotor skills, (7) tracking and (8) driving. In addition to the performance aspect, the classification system takes into account mood and social behaviour variables related to driving safety like tiredness or aggression. Following the evaluation method of vote-counting, the number of significant findings and the number of non-significant findings were summarised per blood alcohol concentration (BAC) group. Thereby, a quantitative estimation of the effects of alcohol depending on the BAC was established, the so-called impairment function, which shows the percentage of significantly impaired findings. In order to provide a general overview of alcohol effects on driving-related performance, a global impairment function was established by aggregating all performance findings. The function is nearly linear with about 30\% significant findings at a BAC of 0.05\% and 50\% significant findings at a BAC of 0.08\%. In addition, more specific impairment functions considering only the findings of the single behavioural categories were calculated. The results revealed that impairment depends not only on the BAC, but also clearly differs between most of the performance categories. Tracking and driving performance were most affected by alcohol with impairment beginning at very low BACs of 0.02\%. Also psychomotor skills were considerably affected by rather low BACs. Impairment of visual functions and information processing occurred at BACs of 0.04\% and increased substantially with higher BACs. Impairment in memory tests could be found with very low BACs of 0.02\%, but varied depending on the kind of memory. Performance decrements in divided attention tests could also be found with very low BACs in some studies. Attention started to be impaired at 0.04\% BAC, but - as in vigilance tasks - considerable impairment only occurred at higher BACs. Choice reaction time was affected at lower BACs than simple reaction time, which was - together with the critical flicker fusion frequency - the least sensitive parameter to the effects of alcohol. To conclude, most skills which are relevant for the safe operation of a vehicle are clearly impaired by BACs of 0.05\%, with motor functions being more affected than cognitive functions and complex tasks more than simple tasks. Generally, the results provided no evidence of a threshold effect for alcohol. There was no driving-related performance category for which a sudden transition from unimpaired to impaired occurred at a particular BAC level. In addition, a comparison was made between the present meta-analysis and two reviews of Moskowitz (Moskowitz \& Fiorentino, 2000; Moskowitz \& Robinson, 1988). Moskowitz reported much lower BACs at which performance was impaired. The reasons for this discrepancy lies in a different way to review scientific findings. On the one hand, Moskowitz focused on significant findings when selecting studies and findings for his reviews. On the other hand, the evaluation method used by Moskowitz ignored non-significant findings and counted each study once at the lowest BAC for which impairment was found. Those non-significant findings are as important as the significant ones in order to determine thresholds of impairment. Therefore, in contrast to Moskowitz, the present work describes the effects of alcohol with functions considering also the non-significant findings. The significance of the non-significant is emphasized with respect to the selection procedure as well as to the evaluation method.}, subject = {Trunkenheit im Verkehr}, language = {en} } @article{SuchotzkiGamer2018, author = {Suchotzki, Kristina and Gamer, Matthias}, title = {Alcohol facilitates detection of concealed identity information}, series = {Scientific Reports}, volume = {8}, journal = {Scientific Reports}, number = {7825}, doi = {10.1038/s41598-018-25811-z}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-176662}, year = {2018}, abstract = {The Concealed Information Test (CIT) is a well-validated means to detect whether someone possesses certain (e.g., crime-relevant) information.

Second, by hampering the inhibition of truthful responses, alcohol intoxication could increase CIT-effects. A correlational field design was employed. Participants (n = 42) were recruited and tested at a bar, where alcohol consumption was voluntary and incidental.

For this reason, BCIs that employ auditory stimuli were suggested. In this study, a multiclass BCI spelling system was implemented that uses animal voices with directional cues to code rows and columns of a letter matrix. To reveal possible training effects with the system, 11 healthy participants performed spelling tasks on 2 consecutive days. In a second step, the system was tested by a participant with amyotrophic lateral sclerosis (ALS) in two sessions. In the first session, healthy participants spelled with an average accuracy of 76\% (3.29 bits/min) that increased to 90\% (4.23 bits/min) on the second day. Spelling accuracy by the participant with ALS was 20\% in the first and 47\% in the second session. The results indicate a strong training effect for both the healthy participants and the participant with ALS. While healthy participants reached high accuracies in the first session and second session, accuracies for the participant with ALS were not sufficient for satisfactory communication in both sessions.

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} } @phdthesis{Hoermann2020, author = {H{\"o}rmann, Markus}, title = {Analyzing and fostering students' self-regulated learning through the use of peripheral data in online learning environments}, doi = {10.25972/OPUS-18009}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-180097}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2020}, abstract = {Learning with digital media has become a substantial part of formal and informal educational processes and is gaining more and more importance. 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.

Contrary to aversive conditioning, appetitive conditioning is rarely investigated in humans, although its importance for normal and pathological behaviors (e.g., obesity, addiction) is undeniable. The present study intents to translate animal findings on appetitive conditioning to humans using food as an US. Thirty-three participants were investigated between 8 and 10 am without breakfast in order to assure that they felt hungry. During two acquisition phases, one geometrical shape (avCS+) predicted an aversive US (painful electric shock), another shape (appCS+) predicted an appetitive US (chocolate or salty pretzel according to the participants' preference), and a third shape (CS) predicted neither US. In a extinction phase, these three shapes plus a novel shape (NEW) were presented again without US delivery. Valence and arousal ratings as well as startle and skin conductance (SCR) responses were collected as learning indices. We found successful aversive and appetitive conditioning. On the one hand, the avCS+ was rated as more negative and more arousing than the CS and induced startle potentiation and enhanced SCR. On the other hand, the appCS+ was rated more positive than the CS and induced startle attenuation and larger SCR.

Traditional emotional theories assume a linear relationship between these dimensions, with valence determining the direction of a behavior (approach vs. withdrawal) and arousal its intensity or strength. In contrast, according to the valence-arousal conflict theory, both dimensions are interactively related: positive valence and low arousal (PL) are associated with an implicit tendency to approach a stimulus, whereas negative valence and high arousal (NH) are associated with withdrawal. Hence, positive, high-arousal (PH) and negative, low-arousal (NL) stimuli elicit conflicting action tendencies. By extending previous research that used several tasks and methods, the present study investigated whether and how emotional valence and arousal affect subjective approach vs. withdrawal tendencies toward emotional words during two novel tasks. In Study 1, participants had to decide whether they would approach or withdraw from concepts expressed by written words. In Studies 2 and 3 participants had to respond to each word by pressing one of two keys labeled with an arrow pointing upward or downward. Across experiments, positive and negative words, high or low in arousal, were presented. In Study 1 (explicit task), in line with the valence-arousal conflict theory, PH and NL words were responded to more slowly than PL and NH words. In addition, participants decided to approach positive words more often than negative words. In Studies 2 and 3, participants responded faster to positive than negative words, irrespective of their level of arousal. Furthermore, positive words were significantly more often associated with "up" responses than negative words, thus supporting the existence of implicit associations between stimulus valence and response coding (positive is up and negative is down). Hence, in contexts in which participants' spontaneous responses are based on implicit associations between stimulus valence and response, there is no influence of arousal. In line with the valence-arousal conflict theory, arousal seems to affect participants' approach-withdrawal tendencies only when such tendencies are made explicit by the task, and a minimal degree of processing depth is required.}, language = {en} } @article{SchroederPfister2015, author = {Schroeder, Philipp A. and Pfister, Roland}, title = {Arbitrary numbers counter fair decisions: trails of markedness in card distribution}, series = {Frontiers in Psychology}, volume = {6}, journal = {Frontiers in Psychology}, doi = {10.3389/fpsyg.2015.00240}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-143481}, pages = {240}, year = {2015}, abstract = {Converging evidence from controlled experiments suggests that the mere processing of a number and its attributes such as value or parity might affect free choice decisions between different actions.

At the same time, other (linguistic) features of a number such as parity are embedded into space and might likewise prime left or right responses through feature words [odd or even, respectively; markedness association of response codes (MARC) effect]. In this experiment we aimed at documenting such influences in a natural setting. We therefore assessed number space and parity space association effects by exposing participants to a fair distribution task in a card playing scenario. Participants drew cards, read out loud their number values, and announced their response choice, i.e., dealing it to a left vs. right player, indicated by Playmobil characters. Not only did participants prefer to deal more cards to the right player, the card's digits also affected response choices and led to a slightly but systematically unfair distribution, supported by a regular SNARC effect and counteracted by a reversed MARC effect.

The results provide no support for the notion that category ambiguity along the DHL is specifically associated with enhanced experience of negative affect.

In comparison, fear is a phasic response to predictable threat. Fear can be experimentally modeled with the help of cue conditioning. Context conditioning, in which the context serves as the best predictor of a threat due to the absence of any conditioned cues, is seen as an operationalization of sustained anxiety. This thesis used a differential context conditioning paradigm to examine sustained attention processes in a threat context compared to a safety context for the first time. In three studies, the attention mechanisms during the processing of contextual anxiety were examined by measuring heart rate responses and steady-state-visually evoked potentials (ssVEPs). An additional focus was set on the processing of social cues (i.e. faces) and the influence of contextual information on these cues. In a last step, the correlates of sustained anxiety were compared to evoked responses by phasic fear, which was realized in a previously established paradigm combining predictable and unpredictable threat. In the first study, a contextual stimulus was associated with an aversive loud noise, while a second context remained unpaired. This conditioning paradigm created an anxiety context (CTX+) and a safety context (CTX-). After acquisition, a social agent vs. an object was presented as a distractor in both contexts. Heart rate and cortical responses, with ssVEPs by using frequency tagging, to the contexts and the distractors were assessed. Results revealed enhanced ssVEP amplitudes for the CTX+ compared to the CTX- during acquisition and during presentation of distractor stimuli. Additionally, the heart rate was accelerated in the acquisition phase, followed by a heart rate deceleration as a psychophysiological marker of contextual anxiety. Study 2 used the same context conditioning paradigm as Study 1. In contrast to the first study, persons with different emotional facial expressions were presented in the anxiety and safety contexts in order to compare the differential processing of these cues within periods of threat and safety. A similar anxiety response was found in the second study, although only participants who Abstract VIII were aware of the contingency between contexts and aversive event showed a sensory amplification of the threat context, indicated by heart rate response and ssVEP activation. All faces irrespective of their emotional expression received increased attentional resources when presented within the anxiety context, which suggests a general hypervigilance in anxiety contexts. In the third study, the differentiation of predictable and unpredictable threat as an operationalization of fear and anxiety was examined on a cortical and physiological level. In the predictable condition, a social cue was paired with an aversive event, while in the unpredictable condition the aversive event remained unpaired with the respective cue. A fear response to the predictable cue was found, indicated by increased oscillatory response and accelerated heart rate. Both predictable and unpredictable threat yielded increased ssVEP amplitudes evoked by the context stimuli, while the response in the unpredictable context showed longer-lasting ssVEP activation to the threat context. To sum up, all three studies endorsed anxiety as a long-lasting defensive response. Due to the unpredictability of the aversive events, the individuals reacted with hypervigilance in the anxiety context, reflected in a facilitated processing of sensory information and an orienting response. This hypervigilance had an impact on the processing of novel cues, which appeared in the anxiety context. Considering the compared stimuli categories, the stimuli perceived in a state of anxiety received increased attentional resources, irrespective of the emotional arousal conveyed by the facial expression. Both predictable and unpredictable threat elicited sensory amplification of the contexts, while the response in the unpredictable context showed longer-lasting sensory facilitation of the threat context.}, subject = {Angst}, language = {en} } @article{MeulePlatte2016, author = {Meule, Adrian and Platte, Petra}, title = {Attentional bias toward high-calorie food-cues and trait motor impulsivity interactively predict weight gain}, series = {Health Psychology Open}, journal = {Health Psychology Open}, doi = {10.1177/2055102916649585}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-168504}, year = {2016}, abstract = {Strong bottom-up impulses and weak top-down control may interactively lead to overeating and, consequently, weight gain.

The first experiment was an emotion classification paradigm which allowed for differentiating reflexive attentional shifts from sustained attention towards diagnostically relevant facial features.

We found that patients as compared to controls reflexively oriented their attention more frequently towards the eyes of emotional faces in the emotion classification paradigm. This initial hypervigilance for the eye region was observed at very early attentional stages when faces were presented for 150 ms, and persisted when facial stimuli were shown for 3 s. Moreover, a delayed attentional orienting into the direction of eye gaze was observed in individuals with social phobia suggesting a differential time course of eye gaze processing in patients and controls.

Bouton (1994) zufolge deutet diese Angstr{\"u}ckkehr durch einen Kontextwechsel darauf hin, dass die Angst nicht gel{\"o}scht wurde. Stattdessen wurde w{\"a}hrend der Expositionssitzung eine neue Assoziation gelernt, die das gef{\"u}rchtete Objekt mit „keiner Angst", also den konditionierten Reiz (conditioned stimulus, CS) mit „keinem unkonditionierten Reiz" (no unconditioned stimulus, no US), verbindet. Bouton argumentiert weiter, dass diese Assoziation kontextabh{\"a}ngig ist, wodurch Effekte wie Angst-Renewal erkl{\"a}rt werden k{\"o}nnen. Da in einem neuen Kontext die CS-no US-Assoziation nicht aktiviert wird, wird die Angst auch nicht gehemmt. Die Kontextabh{\"a}ngigkeit der CS-no US-Assoziation wurde in mehreren Studien belegt (Balooch \& Neumann, 2011; Siavash Bandarian Balooch, Neumann, \& Boschen, 2012; Culver, Stoyanova, \& Craske, 2011; Kim \& Richardson, 2009; Neumann \& Kitlertsirivatana, 2010). Aktuell konzentriert sich die Forschung zur Therapie von Angstst{\"o}rungen auf die Frage, wie Angst reduziert und gleichzeitig ein R{\"u}ckfall verhindert werden kann. Hierzu werden verschiedene Expositionsprotokolle untersucht, wie zum Beispiel (1) Exposition in mehreren Kontexten (multiple contexts exposure, MCE), um Renewal zu reduzieren (z.B. Balooch \& Neumann, 2011); (2) verl{\"a}ngerte Exposition (prolonged exposure, PE), um die hemmende Assoziation w{\"a}hrend des Extinktionslernes zu st{\"a}rken (z.B. Thomas, Vurbic, \& Novak, 2009) und (3) Rekonsolidierungs-Updates (reconsolidation update, RU), die den Rekonsolidierungsprozess durch eine kurze Exposition des CS+ vor der eigentlichen Exposition aktualisieren sollen (Schiller et al., 2010). Bisher liegen jedoch nur sehr wenige Studien vor, die diese neuen Expositionsprotokolle an klinischen Stichproben untersucht haben, und - soweit bekannt - keine Studie, welche die Wirkmechanismen dieser Protokolle an einer klinischen Stichprobe erforscht. Die vorliegende Dissertation hat drei Ziele. Das erste Ziel besteht darin zu pr{\"u}fen, ob Expositionstherapie in multiplen Kontexten die Wahrscheinlichkeit von Renewal reduziert. Das zweite Ziel ist die Untersuchung der Mechanismen, die dem Effekt der Exposition in multiplen Kontexten zugrunde liegen und das dritte ist den Kontext im Zusammenhang mit Konditionierung und Extinktion zu konzeptualisieren. Insgesamt wurden drei Studien durchgef{\"u}hrt. Die erste Studie untersuchte den Effekt von Exposition in multiplen Kontexten auf Renewal, die zweite und dritte Studie die Wirkmechanismen von MCE. In der ersten Studie wurden spinnenphobische Probanden (N = 30) viermal mit einer virtuellen Spinne konfrontiert. Die Expositionstrials wurden entweder in einem gleichbleibenden Kontext oder in vier verschiedenen Kontexten durchgef{\"u}hrt. Am Ende der Sitzung absolvierten alle Teilnehmer einen virtuellen Renewaltest, bei dem die virtuelle Spinne in einem neuen Kontext gezeigt wurde, und einen in vivo Verhaltensvermeidungstest (behavioral avoidance test, BAT) mit einer echten Spinne. Die Ergebnisse zeigten, dass Probanden, welche die vier Expositionstrials in unterschiedlichen Kontexten erfuhren, weniger Angst, sowohl im virtuellen Renewaltest als auch im BAT, erlebten. In dieser Studie konnte die Wirksamkeit von MCE f{\"u}r die Reduktion von Renewal erfolgreich nachgewiesen werden. Studie 2 (N = 35) untersuchte die Wirkmechanismen von MCE in einem differentiellen Konditionierungsparadigma. Die Extinktion wurde in multiplen Kontexten durchgef{\"u}hrt. Hierbei war das Ziel, eine {\"a}hnliche Verminderung von Renewal wie in Studie 1 nachzuweisen. Der Extinktion folgten zwei Tests, mit dem Ziel m{\"o}gliche hemmende Effekte des Kontexts, die w{\"a}hrend der Extinktionsphase erworben wurden, aufzudecken. Bez{\"u}glich des Effektes von MCE wurden drei Hypothesen aufgestellt: (1) Der Extinktionskontext wird mit der Exposition assoziiert, fungiert folglich w{\"a}hrend der Extinktion als Sicherheitssignal und konkurriert daher mit dem Sicherheitslernen des CS. Dies f{\"u}hrt zu einem verminderten Extinktionseffekt auf den CS, wenn die Extinktion nur in einem Kontext durchgef{\"u}hrt wird. (2) Die Elemente im Extinktionskontext (z.B. Raumfarbe, M{\"o}bel) stehen im Zusammenhang mit der CS-no US-Assoziation und erinnern daher an die Extinktion, was zu einer gr{\"o}ßeren Angsthemmung f{\"u}hrt, wenn sie w{\"a}hrend eines Tests gezeigt werden. (3) Nach der emotionalen Prozesstheorie (emotional process theory; Bouton, 1994; Foa et al., 1996) bestimmen die Therapieprozessfaktoren die St{\"a}rke des Renewals. Beispielsweise korrelieren initiale Angstaktivierung, Aktivierung in und zwischen den Sitzungen mit der St{\"a}rke des Renewals. Jedoch waren in dieser Studie keine Unterschiede zwischen den Gruppen im Renewaltest zu beobachten, weswegen die Ergebnisse der zwei Nachtests nicht zu interpretieren sind. Das Ziel von Studie 3 (N = 61) war es, das Konzept des Kontexts im Rahmen von Konditionierung und Exposition zu definieren. In Studie 3 wurde das Auftreten der Generalisierungsabnahme (generalization decrement) genutzt, bei der eine konditionierte Reaktion infolge eines Kontextwechsels nur reduziert auftritt. Auf diesem Weg kann Kontext{\"a}hnlichkeit quantifiziert werden. Nach einer Akquisitonsphase in einem Kontext wurden die Teilnehmer in einem von drei verschiedenen Kontexten getestet. Zwei dieser Kontexte unterschieden sich nur in einer Dimension (Anordnung der Objekte vs. Objekteigenschaften). Die dritte Gruppe wurde im Akquisitonskontext getestet und diente als Kontrollgruppe. Es fanden sich jedoch keine Unteschiede zwischen den Gruppen in den Testphasen. Eine m{\"o}gliche Erkl{\"a}rung ist die Neuartigkeit des Testkontextes. Teilnehmer, die nach der Extinktion einem neuen Kontext ausgesetzt waren, erwarteten in einem anderen Kontext eine zweite Extinktionsphase und zeigten daher mehr statt weniger Angst als erwartet.}, subject = {Angst}, language = {en} } @phdthesis{Kaethner2015, author = {K{\"a}thner, Ivo R.

As a means of communication, in particular BCIs based on event-related potentials (ERPs) as control signal have been researched. Most of these BCIs rely on visual stimulation and have been investigated with healthy participants in controlled laboratory environments. In proof-of-principle studies targeted end users gained control over BCI systems; however, these systems are not yet established as an assistive technology for persons who would most benefit from them. The main aim of this thesis is to advance the usability of ERP-BCIs for target users. To this end, five studies with BCIs have been conducted that enabled users to communicate by focusing their attention on external stimuli. Two studies were conducted in order to demonstrate the advantages and to further improve the practical application of visual BCIs. In the first study, mental workload was experimentally manipulated during prolonged BCI operation. The study showed the robustness of the visual ERP-BCI since users maintained a satisfactory level of control despite constant distraction in the form of background noise. Moreover, neurophysiological markers that could potentially serve as indicators of high mental workload or fatigue were revealed. This is a first step towards future applications in which the BCI could adapt to the mental state of the user (e.g. pauses if high mental workload is detected to prevent false selections). In the second study, a head-mounted display (HMD), which assures that stimuli are presented in the field of view of the user, was evaluated. High accuracies and information transfer rates, similar to a conventional display, were achieved by healthy participants during a spelling task. Furthermore, a person in the locked-in state (LIS) gained control over the BCI using the HMD. The HMD might be particularly suited for initial communication attempts with persons in the LIS in situations, where mounting a conventional monitor is difficult or not feasible. Visual ERP-BCIs could prove valuable for persons with residual control over eye muscles and sufficient vision. However, since a substantial number of target users have limited control over eye movements and/or visual impairments, BCIs based on non-visual modalities are required. Therefore, a main aspect of this thesis was to improve an auditory paradigm that should enable motor impaired users to spell by focusing attention on different tones. The two conducted studies revealed that healthy participants were able to achieve high spelling performance with the BCI already in the first session and stress the importance of the choice of the stimulus material. The employed natural tones resulted in an increase in performance compared to a previous study that used artificial tones as stimuli. Furthermore, three out of five users with a varying degree of motor impairments could gain control over the system within the five conducted sessions. Their performance increased significantly from the first to the fifth session - an effect not previously observed for visual ERP-BCIs. Hence, training is particularly important when testing auditory multiclass BCIs with potential users. A prerequisite for user satisfaction is that the BCI technology matches user requirements. In this context, it is important to compare BCIs with already established assistive technology. Thus, the fifth study of this dissertation evaluated gaze dependent methods (EOG, eye tracking) as possible control signals for assistive technology and a binary auditory BCI with a person in the locked-in state. The study participant gained control over all tested systems and rated the ease of use of the BCI as the highest among the tested alternatives, but also rated it as the most tiring due to the high amount of attention that was needed for a simple selection. Further efforts are necessary to simplify operation of the BCI. The involvement of end users in all steps of the design and development process of BCIs will increase the likelihood that they can eventually be used as assistive technology in daily life. The work presented in this thesis is a substantial contribution towards the goal of re-enabling communication to users who cannot rely on motor activity to convey their thoughts.}, subject = {Gehirn-Computer Schnittstelle}, language = {en} } @article{KruegerKohnenLienert1980, author = {Kr{\"u}ger, Hans-Peter and Kohnen, Ralf and Lienert, Gustav A.}, title = {Aufgabenvariation als Aktivationsparameter in Tranqualizer-Untersuchungen}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-41016}, year = {1980}, abstract = {No abstract available}, language = {de} } @phdthesis{Herber2014, author = {Herber, Kristina}, title = {Ausl{\"o}ser und Modifikation emotionalen Essverhaltens - Feldstudien zum emotionalen Essverhalten und seiner Ver{\"a}nderung durch ein achtsamkeitsbasiertes Training}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-112312}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2014}, abstract = {Emotionale Esser neigen dazu, in emotional belastenden Situationen {\"u}berwiegend s{\"u}ße und fettreiche Nahrung h{\"a}ufig in Abwesenheit von Hunger zu essen, um negative Gef{\"u}hle zu bew{\"a}ltigen.

For this purpose, 9 studies were conducted that employed direct and indirect measures of attitudes, biological measures of affect as well as measures of real eating behavior and food choice, and compared responses of deprived and non deprived subjects on each of these measures. Spontaneous facial reactions were assessed via EMG and revealed that food deprived subjects showed weaker disgust reactions than satiated participants when being confronted with photographs of disgusting foods. Interestingly, deprived and non deprived subjects evaluated disgusting foods equally negative on a conscious level of information processing, indicating that food deprivation has the potential to attenuate food related disgust irrespective of conscious evaluations. Furthermore, it was found that food deprived participants readily consumed disgust related foods ("genetically modified foods"), while satiated participants rejected those foods. Again, no difference emerged between deprived and non deprived subjects in respect to their conscious evaluations of genetically modified foods (that were negative in both experimental groups). The dissociation between conscious evaluations and actual eating behavior that was observed amongst food deprived participants resembles the dissociation between conscious evaluations and facial reactions, thereby corroborating the assumption that alterations in food related disgust might directly influence eating behavior without changing conscious evaluations of foods. The assumption that a shift in automatic attitudes towards disgusting foods might be responsible for these effects received only partial support. That is, there was only a non significant tendency for food deprived subjects to evaluate disgusting foods more positive than satiated subjects on an automatic level of information processing. Instead, the results of the present thesis suggest that food deprived subjects exhibit a stronger motivation than satiated subjects to approach disgusting foods immediately. More precisely, food deprived participants exhibited strong approach motivational tendencies towards both, palatable and disgusting foods in an "Approach- Avoidance Task" whereas satiated participants only approached palatable (but not disgusting) foods on an automatic level of information processing. Moreover, food deprivation seems to change the subjective weighting of hedonic and functional food attributes in the context of more elaborated decisions about which foods to pick for consumption and which foods to reject. It was found that individual taste preferences were of minor importance for food deprived subjects but very important for satiated subjects when actually choosing between several food alternatives. In contrast, functional food attributes (e.g., immediate availability of a given food, large portion size) were more important selection criteria for food deprived subjects than for satiated subjects. Thus, food deprived participants were less picky than satiated participants, but showed a clear preference for those food alternatives that were functional in ending a state of food deprivation quickly - even if this meant choosing a food that was not considered tasty. Taken together, the present thesis shows that physiological need states (e.g., food deprivation) are tightly linked to the affective and motivational processing of need relevant cues. This link is so strong that food deprivation even modulates affective and motivational reactions as well as eating behavior and choice behavior towards disgusting (but need relevant) foods.}, subject = {Ekel}, 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{Schecklmann2009, author = {Schecklmann, Martin}, title = {Behavioraler und hirnphysiologischer Zusammenhang von Arbeitsged{\"a}chtnis und Antworthemmung bei adulter Aufmerksamkeitsdefizit-/Hyperaktivit{\"a}tsst{\"o}rung}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-36466}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2009}, abstract = {Hintergrund: Die Aufmerksamkeitsdefizit-/Hyperaktivit{\"a}tsst{\"o}rung (ADHS) umfasst die klinischen Symptome Hyperaktivit{\"a}t, Impulsivit{\"a}t und Unaufmerksamkeit und besitzt eine große erbliche Komponente. Ver{\"a}nderungen des Dopaminstoffwechsels und des pr{\"a}frontalen Kortex scheinen mit der Erkrankung assoziiert zu sein. Bekannt sind auch Defizite in exekutiven Funktionen wie Arbeitsged{\"a}chtnis und Antworthemmung, welche gemeinsam als ein Endoph{\"a}notyp der ADHS betrachtet werden. Solche sogenannten intermedi{\"a}ren Ph{\"a}notypen bilden m{\"o}glicherweise {\"a}tiopathogenetisch sinnvollere Untergruppen von Krankheitsbildern als die Unterteilung nach den klassischen Diagnosesystemen. Zahlreiche Untersuchungen zu Arbeitsged{\"a}chtnis und Antworthemmung bei ADHS finden Mittelwertsunterschiede im Vergleich zu gesunden Stichproben in behavioralen und hirnphysiologischen Maßen. Ein genetischer Polymorphismus (Val158Met) mit Einfluss auf die Synthese der Catechol-O-Methyltransferase (COMT) moduliert Arbeitsged{\"a}chtnis und Antworthemmung bei Gesunden und Patienten mit ADHS. COMT ist ein Enzym, das den Abbau von pr{\"a}frontalem Dopamin katalysiert. Das Valin(Val)-Allel ist mit einer geringeren, das Methionin(Met)-Allel mit einer h{\"o}heren Verf{\"u}gbarkeit von Dopamin in kortikalen Arealen assoziiert. Letzteres scheint die Funktion pr{\"a}frontaler Hirnareale zu optimieren. Ziel: Es ist unklar, ob die beiden Prozesse Arbeitsged{\"a}chtnis und Antworthemmung miteinander in Verbindung stehen, also einen gemeinsamen Endoph{\"a}notypen bezeichnen, und ob ein m{\"o}glicher Zusammenhang dieser beiden Funktionen durch Dopamin moduliert wird. Gegenstand der vorliegenden Arbeit ist, (1) die bekannten Mittelwertsunterschiede zwischen Patienten mit ADHS und gesunden Kontrollpersonen zu replizieren, (2) den Zusammenhang von Arbeitsged{\"a}chtnis und Antworthemmung mit Korrelationsanalysen zu {\"u}berpr{\"u}fen, (3) den Einfluss des COMT-Polymorphismus auf Arbeitsged{\"a}chtnis und Antworthemmung zu untersuchen und (4) festzustellen, ob der COMT-Polymorphismus die St{\"a}rke der Korrelationen beeinflusst. Die Fragestellungen 3 und 4 sind aufgrund der kleinen Stichproben als explorativ zu bewerten. Methoden: In die Auswertung aufgenommen wurden 45 erwachsene Patienten mit ADHS und 41 nach Alter, Geschlecht, H{\"a}ndigkeit, Intelligenz, Bildungsniveau und Kopfumfang vergleichbare Kontrollen. Arbeitsged{\"a}chtnis und Antworthemmung wurden durch eine N-Back- bzw. eine Stoppsignal-Aufgabe operationalisiert. Als abh{\"a}ngige Variablen dienten als behaviorale Maße die Anzahl richtiger Antworten, Reaktionszeiten und Effizienz und als hirnphysiologische Parameter Konzentrationsver{\"a}nderungen von oxygeniertem (O2Hb) und deoxygeniertem H{\"a}moglobin (HHb) in pr{\"a}frontalen Arealen, die mittels funktioneller Nah-Infrarot Spektroskopie gemessen wurden. Korrelationen wurden zwischen den Kontrollbedingungen (1-Back und Go-Trials) und zwischen den eigentlichen Bedingungen der Arbeitsged{\"a}chtnis- und Stoppsignal-Aufgabe (2-Back und Stopperfolge) berechnet. Ergebnisse: Kontrollen und Patienten zeigten hirnphysiologisch aufgabentypische signifikante Aktivierungsmuster, f{\"u}r das Arbeitsged{\"a}chtnis mehr ausgepr{\"a}gt {\"u}ber dem dorso-lateralen pr{\"a}frontalen Kortex (DLPFC), f{\"u}r die Antworthemmung mehr {\"u}ber dem inferioren frontalen Kortex (IFC). Fragestellung 1: Patienten zeigten im Vergleich zu den gesunden Kontrollpersonen signifikante Defizite in allen erhobenen behavioralen Maßen. Sie zeigten auch signifikant reduzierte Anstiege von O2Hb {\"u}ber dem linken und rechten IFC f{\"u}r Stopperfolge und eine statistisch tendenziell verringerte O2Hb-Konzentration im linken DLPFC f{\"u}r die 2-Back-Bedingung. Es fanden sich jedoch auch Defizite in den einfachen Kontrollaufgaben (behaviorale Maße und O2Hb w{\"a}hrend 1-Back). Nach einer Anpassung der Gruppen f{\"u}r die Unterschiede in den Kontrollaufgaben blieben die Gruppenunterschiede in den Aufgaben f{\"u}r Arbeitsged{\"a}chtnis und Antworthemmung bestehen. Fragestellung 2: Nur bei den Patienten und nur f{\"u}r die behavioralen Maße zeigten sich signifikante positive Assoziationen. Die Effizienz w{\"a}hrend 1-Back korrelierte mit der Reaktionszeit w{\"a}hrend der Go-Trials, und die Effizienz w{\"a}hrend 2-Back korrelierte mit der Stoppsignal-Reaktionszeit. Diese beiden Korrelationen unterschieden sich statistisch nicht in ihrer St{\"a}rke. In den f{\"u}r die Unterschiede in den Kontrollaufgaben angepassten Gruppen blieb nur die Korrelation der Kontrollaufgaben tendenziell signifikant, die Korrelation von Effizienz w{\"a}hrend 2-Back und Stoppsignal-Reaktionszeit verschwand. Die Patienten zeigten erh{\"o}hte Impulsivit{\"a}t (erhoben mit einem Fragebogen), die positiv mit behavioralen Maßen der beiden untersuchten Prozesse korrelierte. Fragestellung 3: F{\"u}r 1-Back (O2Hb in rechter Hemisph{\"a}re) und 2-Back (O2Hb in linker Hemisph{\"a}re) wurden statistisch tendenzielle COMT x Gruppe Interaktionen gefunden. F{\"u}r 1-Back zeigten die Kontrollen mit dem Val/Val-Genoytp sowohl im Vergleich zu Kontrollen mit dem Met/Met-Genotyp als auch im Vergleich zu Patienten mit zwei Val-Allelen eine signifikant h{\"o}here O2Hb-Konzentration. Gleichzeitig wies die Analyse der Verhaltensdaten auf eine h{\"o}here Effizienz der Kontrollen mit Met-Allelen im Vergleich zu Patienten mit Met-Allelen hin. F{\"u}r 2-Back zeigte der Val/Val-Genotyp der Kontrollen eine h{\"o}here O2Hb-Konzentration als der Val/Val-Genotyp der Patienten. Zus{\"a}tzlich wies der Met/Met-Genotyp in der ADHS-Gruppe einen st{\"a}rkeren Anstieg von O2Hb im Vergleich zu dem Val/Val-Genotyp in der ADHS-Gruppe auf. Die Analyse der Verhaltensdaten zeigte eine h{\"o}here Effizienz der Kontrollen im Vergleich zu den Patienten f{\"u}r die Gruppen mit einem oder zwei Val-Allelen. F{\"u}r Stopperfolge zeigten sich signifikante COMT x Gruppe Interaktionen f{\"u}r O2Hb in beiden Hemisph{\"a}ren. Die Kontrollen mit Val/Met-Genotyp hatten h{\"o}here O2Hb-Konzentrationen als Kontrollen mit Val/Val- oder Met/Met-Genotyp und als Patienten mit Val/Met-Genotyp. Patienten mit Val/Met-Genotyp hatten langsamere Stoppsignal-Reaktionszeiten im Vergleich zu den Kontrollen mit Val/Met-Genotyp. Fragestellung 4: Die Korrelationen in Abh{\"a}ngigkeit der Stichproben und COMT-Gruppen zeigten unterschiedlich hohe und unterschiedlich gerichtete Korrelationskoeffizienten. Nur in der Gruppe der Patienten und nur f{\"u}r die Verhaltensdaten wurden positive Assoziationen f{\"u}r alle COMT-Gruppen gefunden, vergleichbar mit den Ergebnissen aus Fragestellung 2. Diskussion: Die behavioralen und hirnphysiologischen Unterschiede in den Aufgaben zum Arbeitsged{\"a}chtnis und zur Antworthemmung zwischen Patienten mit ADHS und Kontrollen replizieren gut die Ergebnisse fr{\"u}herer Arbeiten. Ausgehend von den Gruppenunterschieden in den einfachen Kontrollaufgaben muss aber {\"u}berlegt werden, inwieweit Patienten mit ADHS auch in einfachen psychomotorischen Aufgaben bereits Defizite zeigen. Die Korrelation behavioraler Maße der eigentlichen Arbeitsged{\"a}chtnis- und Inhibitionsaufgabe in der Gruppe der Patienten, die allerdings die Assoziation der Kontrollaufgaben nicht {\"u}berschritt, und die mit dem Anpassen f{\"u}r Unterschiede in den Kontrollenaufgaben verschwand, l{\"a}sst Zweifel an dem spezifischen Zusammenhang der beiden Prozesse bei ADHS aufkommen. Zudem werfen die positiven Assoziationen dieser Prozesse (behaviorale Maße) mit der Impulsivit{\"a}t (Fragebogen) die Frage auf, ob es sich um die Operationalisierung des gleichen Konstrukts handelt bzw. ob Impulsivit{\"a}t in Form behavioraler Tests das Gleiche misst wie Impulsivit{\"a}t auf symptomatischer Ebene. Ein Faktor, der m{\"o}glicherweise Einfluss auf die Korrelationen zwischen den Aufgaben hat, k{\"o}nnte der Dopamingehalt sein, wie er in der vorliegenden Arbeit durch den COMT Polymorphismus operationalisiert wurde. Die Ergebnisse der COMT x Gruppe Interaktionen zeigten eine erh{\"o}hte O2Hb-Konzentration der Val-Alleltr{\"a}ger der Kontrollen f{\"u}r die N-Back-Aufgaben bei teilweise besserer Effizienz und eine erh{\"o}hte O2Hb-Konzentration und teilweise schnellere Stoppsignal-Reaktionszeit der Val/Met-Alleltr{\"a}ger der Kontrollen bei Stopperfolgen. Unsere Ergebnisse entsprechen nicht unbedingt den Annahmen aus der Literatur, dass das Met-Allel das g{\"u}nstige Allel in Bezug auf gute pr{\"a}frontale Hirnfunktion sei. Diese Unterschiede in den COMT x Gruppe Interaktionen legen eine Abh{\"a}ngigkeit pr{\"a}frontaler Hirnfunktionen vom allgemeinen dopaminergen Gehalt (Patienten vs. Kontrollen), vom pr{\"a}frontalen dopaminergen Niveau (COMT-Genotyp) und von der Aufgabenart (Arbeitsged{\"a}chtnis vs. Antworthemmung) nahe. Diese Hypothese wird unterst{\"u}tzt durch die Unterschiede in den Korrelationskoeffizienten der beiden Prozesse in Abh{\"a}ngigkeit der Stichproben und Genotyp-Gruppen. Schlussfolgerung: Die Befunde st{\"u}tzen nicht die Annahme, dass es sich bei Arbeitsged{\"a}chtnis und Antworthemmung um zusammenh{\"a}ngende Funktionen bei ADHS oder Gesunden handelt, oder dass der exekutive Endoph{\"a}notyp einen einheitlichen Subtyp der ADHS darstellt. Zudem scheint eine m{\"o}gliche Assoziation der beiden Prozesse von mehreren Faktoren wie z. B. der Dopamin-Konzentration moduliert zu werden. Zuk{\"u}nftige Arbeiten sollten die Fragestellungen bearbeiten, welche Faktoren den Zusammenhang dieser Prozesse beeinflussen und welche Kombination solcher Faktoren eine Subgruppe von Patienten mit ADHS mit einem gemeinsamen exekutiven Endoph{\"a}notyp darstellen k{\"o}nnten.}, subject = {ADHS}, language = {de} } @article{ReisPfister2022, author = {Reis, Moritz and Pfister, Roland}, title = {Being Observed Does Not Boost Rule Retrieval}, series = {Advances in Cognitive Psychology}, volume = {18}, journal = {Advances in Cognitive Psychology}, number = {3}, doi = {10.5709/acp-0359-8}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-301089}, pages = {173 -- 178}, year = {2022}, abstract = {Previous research, mainly focusing on the situational preconditions of rule violations, indicates that feelings of being watched by other agents promote rule compliance.

In this study, we investigated whether cues of being observed not only reduce the likelihood of violating rules but also affect the underlying cognitive processes of such behavior when still putting a rule violation into action. Therefore, we applied a motion-tracking paradigm in which participants could violate a simple stimulus-response mapping rule while being faced with pictures of either open or closed eyes. In line with prior research, temporal and spatial measures of the participants' movements indicated that violating this rule induced substantial cognitive conflict. However, conflict during rulebreaking was not moderated by the eye stimuli.

Specifically, task order switches (vs. repetitions) yield performance costs (i.e., task-order switch costs), suggesting that task order scheduling is a vital part of configuring a task set. Recently, it has been shown that this process takes specific task-related characteristics into account: task order switches were easier when switching to a preferred (vs. non-preferred) task order. Here, we ask whether another determinant of task order control, namely the phenomenon that a task order switch in a previous trial facilitates a task order switch in a current trial (i.e., a sequential modulation of task order switch effect) also takes task-specific characteristics into account. Based on three experiments involving task order switches between a preferred (dominant oculomotor task prior to non-dominant manual/pedal task) and a non-preferred (vice versa) order, we replicated the finding that task order switching (in Trial N) is facilitated after a previous switch (vs. repetition in Trial N - 1) in task order. There was no substantial evidence in favor of a significant difference when switching to the preferred vs. non-preferred order and in the analyses of the dominant oculomotor task and the non-dominant manual task. This indicates different mechanisms underlying the control of immediate task order configuration (indexed by task order switch costs) and the sequential modulation of these costs based on the task order transition type in the previous trial.}, language = {en} } @article{ZilligPauliWieseretal.2023, author = {Zillig, Anna-Lena and Pauli, Paul and Wieser, Matthias and Reicherts, Philipp}, title = {Better safe than sorry? - On the influence of learned safety on pain perception}, series = {PloS One}, volume = {18}, journal = {PloS One}, number = {11}, doi = {10.1371/journal.pone.0289047}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-349905}, year = {2023}, abstract = {The experience of threat was found to result—mostly—in increased pain, however it is still unclear whether the exact opposite, namely the feeling of safety may lead to a reduction of pain. To test this hypothesis, we conducted two between-subject experiments (N = 94; N = 87), investigating whether learned safety relative to a neutral control condition can reduce pain, while threat should lead to increased pain compared to a neutral condition. Therefore, participants first underwent either threat or safety conditioning, before entering an identical test phase, where the previously conditioned threat or safety cue and a newly introduced visual cue were presented simultaneously with heat pain stimuli. Methodological changes were performed in experiment 2 to prevent safety extinction and to facilitate conditioning in the first place: We included additional verbal instructions, increased the maximum length of the ISI and raised CS-US contingency in the threat group from 50\% to 75\%. In addition to pain ratings and ratings of the visual cues (threat, safety, arousal, valence, and contingency), in both experiments, we collected heart rate and skin conductance. Analysis of the cue ratings during acquisition indicate successful threat and safety induction, however results of the test phase, when also heat pain was administered, demonstrate rapid safety extinction in both experiments. Results suggest rather small modulation of subjective and physiological pain responses following threat or safety cues relative to the neutral condition. However, exploratory analysis revealed reduced pain ratings in later trials of the experiment in the safety group compared to the threat group in both studies, suggesting different temporal dynamics for threat and safety learning and extinction, respectively.

As expected, unpleasant pictures strongly activated the right and left amygdala, the right hippocampus, and the medial occipital lobe, whereas pleasant pictures elicited significant activations in left occipital regions, and in parts of the medial temporal lobe. The direct comparison of unpleasant and pleasant pictures, which were comparable in arousal clearly indicated stronger amygdala activation in response to the unpleasant pictures. Most important, correlational analyses revealed on the one hand that the arousal of unpleasant pictures was significantly associated with activations in the right amygdala and the left caudate body. On the other hand, valence of pleasant pictures was significantly correlated with activations in the right caudate head, extending to the nucleus accumbens (NAcc) and the left dorsolateral prefrontal cortex. These findings support the notion that the amygdala is primarily involved in processing of unpleasant stimuli, particularly to more arousing unpleasant stimuli.

This study investigated brain mechanisms underlying these anticipatory processes. We induced dyspnea using resistive-load breathing in healthy subjects during functional magnetic resonance imaging. Blocks of severe and mild dyspnea alternated, each preceded by anticipation periods. Severe dyspnea activated a network of sensorimotor, cerebellar, and limbic areas. The left insular, parietal opercular, and cerebellar cortices showed increased activation already during dyspnea anticipation. Left insular and parietal opercular cortex showed increased connectivity with right insular and anterior cingulate cortex when severe dyspnea was anticipated, while the cerebellum showed increased connectivity with the amygdala. Notably, insular activation during dyspnea perception was positively correlated with midbrain activation during anticipation. Moreover, anticipatory fear was positively correlated with anticipatory activation in right insular and anterior cingulate cortex. The results demonstrate that dyspnea anticipation activates brain areas involved in dyspnea perception. The involvement of emotion-related areas such as insula, anterior cingulate cortex, and amygdala during dyspnea anticipation most likely reflects anticipatory fear and might underlie the development of unfavorable health behaviors in patients suffering from dyspnea.}, language = {en} } @phdthesis{Botrel2018, author = {Botrel, Loic}, title = {Brain-computer interfaces (BCIs) based on sensorimotor rhythms - Evaluating practical interventions to improve their performance and reduce BCI inefficiency}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-168110}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2018}, abstract = {Brain computer interfaces based on sensorimotor rhythms modulation (SMR-BCIs) allow people to emit commands to an interface by imagining right hand, left hand or feet movements. The neurophysiological activation associated with those specific mental imageries can be measured by electroencephalography and detected by machine learning algorithms. Improvements for SMR-BCI accuracy in the last 30 years seem to have reached a limit. The currrent main issue with SMR-BCIs is that between 15\% to 30\% cannot use the BCI, called the "BCI inefficiency" issue. Alternatively to hardware and software improvements, investigating the individual characteristics of the BCI users has became an interesting approach to overcome BCI inefficiency. In this dissertation, I reviewed existing literature concerning the individual sources of variation in SMR-BCI accuracy and identified generic individual characteristics. In the empirical investigation, attention and motor dexterity predictors for SMR-BCI performance were implemented into a trainings that would manipulate those predictors and lead to higher SMR-BCI accuracy. Those predictors were identified by Hammer et al. (2012) as the ability to concentrate (associated with relaxation levels) and "mean error duration" in a two-hand visuo-motor coordination task (VMC). Prior to a SMR-BCI session, a total of n=154 participants in two locations took part of 23 min sessions of either Jacobson's Progressive Muscle Relaxation session (PMR), a VMC session, or a control group (CG). No effect of PMR or VMC manipulation was found, but the manipulation checks did not consistently confirm whether PMR had an effect of relaxation levels and VMC on "mean error duration". In this first study, correlations between relaxation levels or "mean error duration" and accuracy were found but not in both locations. A second study, involving n=39 participants intensified the training in four sessions on four consecutive days or either PMR, VMC or CG. The effect or manipulation was assessed for in terms of a causal relationship by using a PRE-POST study design. The manipulation checks of this second study validated the positive effect of training on both relaxation and "mean error duration". But the manipulation did not yield a specific effect on BCI accuracy. The predictors were not found again, displaying the instability of relaxation levels and "mean error duration" in being associated with BCI performance. An effect of time on BCI accuracy was found, and a correlation between State Mindfulness Scale and accuracy were reported. Results indicated that a short training of PMR or VMC were insufficient in increasing SMR-BCI accuracy. This study contrasted with studies succeeding in increasing SMR-BCI accuracy Tan et al. (2009, 2014), by the shortness of its training and the relaxation training that did not include mindfulness. It also contrasted by its manipulation checks and its comprehensive experimental approach that attempted to replicate existing predictors or correlates for SMR-BCI accuracy. The prediction of BCI accuracy by individual characteristics is receiving increased attention, but requires replication studies and a comprehensive approach, to contribute to the growing base of evidence of predictors for SMR-BCI accuracy. While short PMR and VMC trainings could not yield an effect on BCI performance, mindfulness meditation training might be beneficial for SMR-BCI accuracy. Moreover, it could be implemented for people in the locked-in-syndrome, allowing to reach the end-users that are the most in need for improvements in BCI performance.}, subject = {Gehirn-Computer-Schnittstelle}, language = {en} } @phdthesis{Kaufmann2013, author = {Kaufmann, Tobias}, title = {Brain-computer interfaces based on event-related potentials: toward fast, reliable and easy-to-use communication systems for people with neurodegenerative disease}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-83441}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2013}, abstract = {Objective: Brain Computer Interfaces (BCI) provide a muscle independent interaction channel making them particularly valuable for individuals with severe motor impairment. Thus, different BCI systems and applications have been proposed as assistive technology (AT) solutions for such patients. The most prominent system for communication utilizes event-related potentials (ERP) obtained from the electroencephalogram (EEG) to allow for communication on a character-by-character basis. Yet in their current state of technology, daily life use cases of such systems are rare. In addition to the high EEG preparation effort, one of the main reasons is the low information throughput compared to other existing AT solutions. Furthermore, when testing BCI systems in patients, a performance drop is usually observed compared to healthy users. Patients often display a low signal-to-noise ratio of the recorded EEG and detection of brain responses may be aggravated due to internally (e.g. spasm) or externally induced artifacts (e.g. from ventilation devices). Consequently, practical BCI systems need to cope with mani-fold inter-individual differences. Whilst these high demands lead to increasing complexity of the technology, daily life use of BCI systems requires straightforward setup including an easy-to-use graphical user interface that nonprofessionals can handle without expert support. Research questions of this thesis: This dissertation project aimed at bringing forward BCI technology toward a possible integration into end-users' daily life. Four basic research questions were addressed: (1) Can we identify performance predictors so that we can provide users with individual BCI solutions without the need of multiple, demanding testing sessions? (2) Can we provide complex BCI technology in an automated, user-friendly and easy-to-use manner, so that BCIs can be used without expert support at end-users' homes? (3) How can we account for and improve the low information transfer rates as compared to other existing assistive technology solutions? (4) How can we prevent the performance drop often seen when bringing BCI technology that was tested in healthy users to those with severe motor impairment? Results and discussion: (1) Heart rate variability (HRV) as an index of inhibitory control (i.e. the ability to allocate attention resources and inhibit distracting stimuli) was significantly related to ERP-BCI performance and accounted for almost 26\% of variance. HRV is easy to assess from short heartbeat recordings and may thus serve as a performance predictor for ERP-BCIs. Due to missing software solutions for appropriate processing of artifacts in heartbeat data (electrocardiogram and inter-beat interval data), our own tool was developed that is available free of charge. To date, more than 100 researchers worldwide have requested the tool. Recently, a new version was developed and released together with a website (www.artiifact.de). (2) Furthermore, a study of this thesis demonstrated that BCI technology can be incorporated into easy-to-use software, including auto-calibration and predictive text entry. Na{\"i}ve, healthy nonprofessionals were able to control the software without expert support and successfully spelled words using the auto-calibrated BCI. They reported that software handling was straightforward and that they would be able to explain the system to others. However, future research is required to study transfer of the results to patient samples. (3) The commonly used ERP-BCI paradigm was significantly improved. Instead of simply highlighting visually displayed characters as is usually done, pictures of famous faces were used as stimulus material. As a result, specific brain potentials involved in face recognition and face processing were elicited. The event-related EEG thus displayed an increased signal-to-noise ratio, which facilitated the detection of ERPs extremely well. Consequently, BCI performance was significantly increased. (4) The good results of this new face-flashing paradigm achieved with healthy participants transferred well to users with neurodegenerative disease. Using a face paradigm boosted information throughput. Importantly, two users who were highly inefficient with the commonly used paradigm displayed high accuracy when exposed to the face paradigm. The increased signal-to-noise ratio of the recorded EEG thus helped them to overcome their BCI inefficiency. Significance: The presented work at hand (1) successfully identified a physiological predictor of ERP-BCI performance, (2) proved the technology ready to be operated by na{\"i}ve nonprofessionals without expert support, (3) significantly improved the commonly used spelling paradigm and (4) thereby displayed a way to effectively prevent BCI inefficiency in patients with neurodegenerative disease. Additionally, missing software solutions for appropriate handling of artifacts in heartbeat data encouraged development of our own software tool that is available to the research community free of charge.

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{Beinicke2017, author = {Beinicke, Andrea}, title = {Career Construction Across the Life Span: Career Choice and Career Development}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-117447}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2017}, abstract = {This dissertation contributes to deepen our understanding of constructs that play a key role in individuals' vocational career construction. In this regard, many previous studies have focused exclusively on a specific phase of an individual's career. Yet, modern societies require continuous investments in one's career to adapt to changing Environments throughout the life span. Consequently, this dissertation takes a broad approach to capture a wide spectrum of career construction processes. According to Super's (1990) developmental stage framework, individuals have to manage vocational developmental tasks corresponding to each of the developmental life stages in order to be career mature across the life span. As the two stages exploration and maintenance set the stage for individuals' future career pathways, they are especially important in individuals' vocational career construction. Therefore, both of them are addressed in this dissertation. By answering open research questions relevant to career choice in early career stages and to career development in later career stages, this dissertation contributes to the overarching goal of shedding more light on constructs relevant to individuals' vocational career construction processes across the life span. Beyond the results presented within each study's horizon, this dissertation aimed at offering practical guidance to career counselors, trainees, and training and development (T\&D) professionals. Career counselors and T\&D professionals are involved in guiding vocational career construction processes of individuals across the life span.

However, the mechanisms how virtual environments elicit and modify fear responses are not yet fully understood. Presence, a psychological construct referring to the 'sense of being there' in a virtual environment, is widely assumed to crucially influence the strength of the elicited fear responses, however, causality is still under debate. The present study is the first that experimentally manipulated both variables to unravel the causal link between presence and fear responses. Height-fearful participants (N = 49) were immersed into a virtual height situation and a neutral control situation (fear manipulation) with either high versus low sensory realism (presence manipulation). Ratings of presence and verbal and physiological (skin conductance, heart rate) fear responses were recorded. Results revealed an effect of the fear manipulation on presence, i.e., higher presence ratings in the height situation compared to the neutral control situation, but no effect of the presence manipulation on fear responses. However, the presence ratings during the first exposure to the high quality neutral environment were predictive of later fear responses in the height situation. Our findings support the hypothesis that experiencing emotional responses in a virtual environment leads to a stronger feeling of being there, i.e., increase presence. In contrast, the effects of presence on fear seem to be more complex: on the one hand, increased presence due to the quality of the virtual environment did not influence fear; on the other hand, presence variability that likely stemmed from differences in user characteristics did predict later fear responses. These findings underscore the importance of user characteristics in the emergence of presence.}, language = {en} } @article{KirschKunde2023, author = {Kirsch, Wladimir and Kunde, Wilfried}, title = {Changes in body perception following virtual object manipulation are accompanied by changes of the internal reference scale}, series = {Scientific Reports}, volume = {13}, journal = {Scientific Reports}, doi = {10.1038/s41598-023-34311-8}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-357876}, year = {2023}, abstract = {Changes in body perception often arise when observers are confronted with related yet discrepant multisensory signals.

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{SodianSchneider1990, author = {Sodian, Beate and Schneider, Wolfgang}, title = {Children's understanding of cognitive cueing: How to manipulate cues to fool a competitor}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-62132}, year = {1990}, abstract = {4-6-year-old children's understanding of cognitive cuing was studied in 2 experiments using a strategic interaction paradigm.

Brain-computer interfaces (BCI) based on electroencephalography represent an important approach to establish communication with these patients. The most common BCI for communication rely on the P300, a positive deflection arising in response to rare events. To foster broader application of BCIs for restoring lost function, also for end-users with impaired vision, we explored whether there were specific time windows during the day in which a P300 driven BCI should be preferably applied. Methods: The present study investigated the influence of time of the day and modality (visual vs. auditory) on P300 amplitude and latency. A sample of 14 patients (end-users) with ALS and 14 healthy age matched volunteers participated in the study and P300 event-related potentials (ERP) were recorded at four different times (10, 12 am, 2, \& 4 pm) during the day. Results: Results indicated no differences in P300 amplitudes or latencies between groups (ALS patients v. healthy participants) or time of measurement. In the auditory condition, latencies were shorter and amplitudes smaller as compared to the visual condition.

Placebo and nocebo effects are among the most prominent examples for such manipulations. Placebo and nocebo manipulations cause reliable psychological and physiological changes, although the administered agent or treatment is inert. The present dissertation aimed at investigating the role of cognitive and emotional influences in the generation of placebo and nocebo effects on pain perception. In addition, the feasibility of solely psychological placebo manipulations to alter the perception of pain was tested. Two commonly discussed preconditions for the generation of placebo and nocebo effects are prior experiences (i.e., past encounter of drug effects) and expectations (i.e., positive or negative attitudes towards an intervention). So far, research on placebo and nocebo effects relied on the administration of sham interventions, which resembled medical treatments like inert pills, creams or injections. However, such experimental procedures deal with confounds due to earlier experiences and expectations resulting from the individual's history with medical interventions. Accordingly, the implementation of a placebo manipulation that is completely new to an individual, seems necessary to disentangle the contribution of experience and expectation for the induction of placebo and nocebo effects. To this end, in Experiment 1 the level of experience and expectation regarding a placebo-nocebo treatment was stepwise manipulated across three different experimental groups. To avoid any resemblances to earlier experiences and individual expectations, a mere psychological placebo-nocebo treatment was chosen that was new to all participants. They were instructed that visual black and white stripe patterns had been found to reliably alter the perception of pain. One group of participants received only the placebo-nocebo instruction (expectation), a second group experienced a placebo-nocebo treatment within a conditioning phase (experience) but no instruction, and a third group received the combination of both that is a placebo-nocebo instruction and a placebo-nocebo conditioning (experience + expectation). It was shown that only the experience + expectation group revealed significantly higher pain ratings and physiological responses during nocebo, compared to placebo trials of the succeeding test phase. These findings demonstrate that the induction of a mere psychological placebo-nocebo effect on pain is in principle possible. Most important, results indicate that such effects most likely rely on both, a positive treatment experience, due to the encounter of an effective intervention (placebo conditioning), and a positive expectation about the intervention (placebo instruction).Besides experience and expectation, the current mood state has been shown to modulate pain and to impact the induction of placebo and nocebo effects. In this vein it has been demonstrated that placebo effects come along with positive affect, while nocebo effects often occur together with elevated feelings of anxiety. To clarify the interaction of emotions and placebo-nocebo manipulations on pain perception, in Experiment 2 the paradigm of Experiment 1 was modified. Instead of black and white stripe patterns, positive and negative emotional pictures were presented, which either cued pain increase (nocebo) or pain decrease (placebo). Two experimental groups were compared, which differed with regard to the instructed contingency of positive pictures serving as placebo and negative pictures serving as nocebo cues or vice versa (congruent vs. incongruent). Results indicate that the differentiation of placebo and nocebo trials (behaviorally and physiologically) was more pronounced for the congruent compared to the incongruent group. However, in the incongruent group, affective pain ratings were also significantly higher for nocebo (positive pictures) than placebo (negative pictures) trials, similar to the congruent group. These findings demonstrate that a placebo-nocebo manipulation is capable to dampen and even reverse the originally pain augmenting effect of negative emotions. The results of Experiment 2 were further corroborated in Experiment 3, when the design was adapted to the fMRI scanner, and again a congruent and an incongruent experimental group were compared. Behavioral, physiological and neurophysiological markers of pain processing revealed a differentiation between nocebo and placebo conditions that was present irrespective of the experimental group. In addition, the fMRI analysis revealed an increased engagement of prefrontal areas for the incongruent group only, supposedly reflecting the reinterpretation or appraisal process when positive pictures were cueing negative outcomes. Taken together, the results of the present studies showed (a) that it is possible to induce a placebo-nocebo effect on pain solely by a psychological manipulation, (b) that both, prior experiences and positive expectation, are necessary preconditions for this placebo-nocebo effect, (c) that the impact of negative emotion on pain can be dampened and even reversed by placebo-nocebo manipulations, and (d) that most likely a cognitive top-down process is crucial for the induction of (psychological) placebo-nocebo effects. These results significantly enhance our understanding of psychological mechanisms involved in the induction of placebo-nocebo effects. Further, a fruitful foundation for future studies is provided, which will need to determine the contributions of primarily nocebo or placebo responses mediating the effects as demonstrated in the present studies. In a long-term perspective, the present findings may also help to exploit placebo effects and prevent from nocebo effect in clinical contexts by further elucidating crucial psychological factors that contribute to the placebo and nocebo response.}, subject = {Placebo}, language = {en} } @book{SmithPasqualiniMachtEllgring2024, author = {Smith Pasqualini, Marcia and Macht, Michael and Ellgring, Heiner}, title = {Cognitive Behavioral Therapy for People with Parkinson's Disease and Caregivers : A Guide for Mental Health Professionals}, publisher = {W{\"u}rzburg University Press}, address = {W{\"u}rzburg}, isbn = {978-3-95826-226-3}, doi = {10.25972/WUP-978-3-95826-227-0}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-345196}, publisher = {W{\"u}rzburg University Press}, pages = {xii, 344}, year = {2024}, abstract = {The need for mental health support within the Parkinson's disease (PD) community has never been greater, yet many practitioners lack the knowledge or experience to address the unique challenges associated with PD.

This hypothesis was supported by the outcome of two out of three experiments. We further manipulated whether all trials or only one random trial determined payoff to modulate reward adaptation over time (Experiment 2) and whether payoff was framed as a financial gain or loss (Experiment 3). The payoff scheme of one random or all trials did not affect lying behavior and, discordant to earlier research, facing losses instead of gains did not increase lying behavior.

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{Wannagat2018, author = {Wannagat, Wienke Charlotte}, title = {Cognitive Processes of Discourse Comprehension in Children and Adults - Comparisons between Written, Auditory, and Audiovisual Modes of Presentation -}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-162515}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2018}, abstract = {In drei Studien wurde untersucht, wie sich unterschiedliche Darbietungsformate (schriftlich, auditiv, audiovisuell (auditiv + Bilder) auf das Verst{\"a}ndnis semantisch identischer Inhalte auswirken. Dabei interessierte insbesondere der Entwicklungsverlauf von der ersten Klasse bis zum Erwachsenenalter. Dass sich Bilder f{\"o}rderlich auf die Verst{\"a}ndnisleistung auswirken k{\"o}nnen, gilt als gut untersucht (z.B. Carney \& Levin, 2002). Anders als viele bisherige Studien erfassen wir Textverstehen mit impliziten Maßen, die differenziertere R{\"u}ckschl{\"u}sse auf die, g{\"a}ngigen Theorien zufolge, zugrundeliegenden Prozesse zulassen: Textverstehen geht mit der Konstruktion von drei Ebenen mentaler Repr{\"a}sentationen einher (vgl. Kintsch, 1998). Weiterhin bedeutet erfolgreiches Textverstehen, eine auf lokaler und globaler Ebene koh{\"a}rente mentale Repr{\"a}sentation zu konstruieren (z.B. Schnotz \& Dutke, 2004). Mit einem Satz-Rekognitionstest (vgl. Schmalhofer \& Glavanov, 1986) untersuchten wir, ob sich das Ged{\"a}chtnis f{\"u}r die Textoberfl{\"a}che, die Textbasis und das Situationsmodell bei 103 8- und 10-J{\"a}hrigen zwischen schriftlicher, auditiver und audiovisueller (Studie 1) und bei 106 7-, 9- und 11-J{\"a}hrigen zwischen auditiver und audiovisueller Darbietung narrativer Texte (Studie 2) unterscheidet. Weiterhin (Studie 3) untersuchten wir mit 155 9- und 11-J{\"a}hrigen, inwieweit sich die F{\"a}higkeit der Inferenzbildung zur Herstellung lokaler und globaler Koh{\"a}renz zwischen schriftlicher, auditiver und audiovisueller Darbietung unterscheidet. Als Indikator dienten die Reaktionszeiten auf W{\"o}rter, die mit einem {\"u}ber (global)- oder untergeordneten (lokal) Protagonistenziel assoziiert sind. Insgesamt zeigte sich, dass Sch{\"u}ler bis zu einem Alter von 11 Jahren nicht nur die Textoberfl{\"a}che besser erinnern, sondern auch besser in der Lage sind ein Situationsmodell zu konstruieren, wenn einem Text Bilder beigef{\"u}gt sind. Dies zeigte sich sowohl im Vergleich mit auditiver als auch mit schriftlicher Darbietung. Bei Erwachsenen zeigte sich kein Effekt der Darbietungsform. Sowohl 9- als auch 11-J{\"a}hrigen gelingt außerdem die Herstellung globaler Koh{\"a}renz bei audiovisueller Darbietung besser als bei auditiver. Die schriftliche Darbietung zeigte sich im Vergleich zur auditiven sowohl im Hinblick auf lokale als auch auf globale Koh{\"a}renz {\"u}berlegen.}, subject = {Textverstehen}, language = {en} } @article{LugoQuitadamoBianchietal.2016, author = {Lugo, Zulay R. and Quitadamo, Lucia R. and Bianchi, Luigi and Pellas, Fr{\´e}deric and Veser, Sandra and Lesenfants, Damien and Real, Ruben G.

We investigated the potential of the P300 as a reliable marker of conscious processing in patients with locked-in syndrome (LIS). Eleven chronic LIS patients and 10 healthy subjects (HS) listened to a complex-tone auditory oddball paradigm, first in a passive condition (listen to the sounds) and then in an active condition (counting the deviant tones). Seven out of nine HS displayed a P300 waveform in the passive condition and all in the active condition. HS showed statistically significant changes in peak and area amplitude between conditions. Three out of seven LIS patients showed the P3 waveform in the passive condition and five of seven in the active condition. No changes in peak amplitude and only a significant difference at one electrode in area amplitude were observed in this group between conditions. We conclude that, in spite of keeping full consciousness and intact or nearly intact cortical functions, compared to HS, LIS patients present less reliable results when testing with ERP, specifically in the passive condition. We thus strongly recommend applying ERP paradigms in an active condition when evaluating consciousness in non-responsive patients.}, language = {en} } @article{WannagatWaizeneggerNiedling2021, author = {Wannagat, Wienke and Waizenegger, Gesine and Niedling, Gerhild}, title = {Coherence formation during narrative text processing: a comparison between auditory and audiovisual text presentation in 9- to 12-year-old children}, series = {Cognitive Processing}, volume = {22}, journal = {Cognitive Processing}, issn = {1612-4782}, doi = {10.1007/s10339-020-01008-z}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-235744}, pages = {299-310}, year = {2021}, abstract = {In an experiment with 114 children aged 9-12 years, we compared the ability to establish local and global coherence of narrative texts between auditory and audiovisual (auditory text and pictures) presentation.

Following each text, we collected the response time to a query word that was either associated with a near or a distant causal antecedent of the final sentence. Analysis of these response times indicated that audiovisual presentation has advantages over auditory presentation for accessing information relevant for establishing both local and global coherence, but there are indications that this effect may be slightly more pronounced for global coherence.}, language = {en} }
