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.

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.

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

The purpose of our study was to examine the effects of such hypothesized neurobiological alterations on the behavioral level, and more precisely on the implicit and explicit reward learning. Alcohol users were classified as dependent drinkers (using the DSM-IV criteria), binge drinkers (using criteria of the USA National Institute on Alcohol Abuse and Alcoholism) or low-risk drinkers (following recommendations of the Scientific board of trustees of the German Health Ministry). The final sample (n = 94) consisted of 36 low-risk alcohol users, 37 binge drinkers and 21 abstinent alcohol dependent patients. Participants were administered a probabilistic implicit reward learning task and an explicit reward- and punishment-based trial-and-error-learning task. Alcohol dependent patients showed a lower performance in implicit and explicit reward learning than low risk drinkers. Binge drinkers learned less than low-risk drinkers in the implicit learning task. The results support the assumption that binge drinking and alcohol dependence are related to a chronic reward deficit. Binge drinking accompanied by implicit reward learning deficits could increase the risk for the development of an alcohol dependence.

Here we investigated if such spatial anticipations can be triggered by symbolic information that participants cannot consciously see. In two experiments involving a Posner cueing task and a visual search task, a central cue informed participants about the likely location of the next target stimulus. 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.

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

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

In intuitions of hidden semantic coherence, people can intuitively detect whether a word triad has a common remote associate (coherent) or not (incoherent) before, and independently from actually retrieving the common associate. The present fluency-affect intuition model (FAIM) maintains that semantic coherence increases the processing fluency for coherent compared to incoherent triads, and that this increased fluency triggers brief and subtle positive affect, which is the experiential basis of these intuitions. Published work concerning 25 experiments is reviewed that gathered empirical support for this model. Furthermore, the impact of fluency and affect was also generalized to intuitions of visual coherence, and intuitions of grammaticality in an artificial grammar learning paradigm. N2 - In der vorliegenden Abhandlung wird für eine prozedurale Betrachtungsweise bei der psychologischen Erforschung intuitiver Urteile gestritten. Obwohl intuitive Urteile in einer Vielzahl von Bereichen untersucht werden (z.B. Bechara, Damasio, Tranel, & Damasio, 1997; Kahneman & Tversky, 1996; Reber, 1967), sind theoretische Modelle und empirische Arbeiten, die die intuitiven Urteilen zugrunde liegenden Prozesse darstellen, selten (e.g., Koriat & Levy-Sadot, 2001). Anhand des kürzlich entwickelten Fluency-Affekt Intuitionsmodells (FAIM) von Topolinski und Strack (2008, 2009a, 2009b, im Druck-a, im Druck -b) wird exemplarisch ein sozialkognitiver Ansatz dargestellt, der systematisch die Prozesse untersucht, die zu Intuitionen von Kohärenz führen. Bei dieser Art von Intuition erspüren Individuen, ob eine Wortgruppe einen gemeinsamen Assoziaten als Lösungswort hat (z.B. SALZ TIEF GISCHT implizieren MEER), oder nur eine zufällige Wortgruppe ist (z.B. TRAUM BALL BUCH), ohne das Lösungswort abrufen zu können (Bowers, Regehr, Balthazard, & Parker, 1990). Insbesondere nimmt das FAIM an, daß beim Lesen einer kohärenten Worttriade schrittweise deren Lösungswort semantisch aktiviert wird, was die Verarbeitungsflüssigkeit (Fluency) kohärenter Triade erhöht im Vergleich zu inkohärenten Triaden (vgl. Whittlesea, 1993). Diese erhöhte Verarbeitungsflüssigkeit löst automatisch einen positiven Affekt aus (vgl., Reber, Schwarz, & Winkielman, 2004), der als kognitives Gefühl als Urteilsgrundlage herangezogen wird (vgl. Schwarz & Clore, 2007). Es werden insgesamt 24 Experimente aus 5 veröffentlichten Arbeiten des Autoren und 1 unveröffentlichtes Experiment besprochen, die empirische Hinweise für die Gültigkeit des FAIM geliefert haben. Wichtige Implikationen für zukünftige Forschung unter einem prozeduralen Fokus auf intuitive Urteile werden besprochen.

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

In der psychologischen Forschung unterscheidet man drei Arten der Perspektivenübernahme, nämlich perzeptuelle (visuo-spatiale), affektive (Empathie) und kognitive (Theory of Mind). Die letztgenannten Arten der Perspektivenübernahme werden oft als „psychologische Perspektivenübernahme“ zusammengefasst. Diese Dissertation befasst sich mit der Frage, ob diese verschiedenen Arten der Perspektivenübernahme als theoretisch unterscheidbare Konstrukte oder lediglich als Facetten ein und desselben Konstrukts angesehen werden sollten. Die Befundlage in der psychologischen Fachliteratur ist diesbezüglich nicht eindeutig. Während einige Autoren Korrelationen zwischen verschiedenen Arten der Perspektivenübernahme für zu gering erachten, um ein einheitliches Konstrukt zu konstatieren, bewerten andere Autoren Korrelationen derselben Größe als Evidenz hierfür. Ein weniger arbiträres Vorgehen wäre es, experimentalpsychologisch zugrunde liegende Mechanismen zu identifizieren, die allen Arten der Perspektivenübernahme gemein sind, und zu untersuchen, ob eine Manipulation dieser Mechanismen abhängige Maße affektiver, kognitiver und perzeptueller Perspektivenübernahme gleichermaßen beeinflusst. Diesem Ansatz folgend macht die vorliegende Arbeit die Annahme, dass die mentale Selbstrotation des Körperschemas in die Position einer anderen Person, der zentrale Mechanismus visuo-spatialer Perspektivenübernahme, ein gemeinsamer Mechanismus aller Arten der Perspektivenübernahme ist. Entgegen früherer Ansätze wird diese Einheit somit nicht nur über die zentrale gemeinsame Funktionalität aller Arten von Perspektivenübernahme, 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 Perspektivenübernahme zu psychologischen Konsequenzen führen kann. Dies wurde in 6 Experimenten getestet. In diesen Experimenten mussten die Probanden zunächst 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 würde. Dabei wurde die Position der Zielperson so manipuliert, dass sie in der Hälfte der Fälle im selben visuo-spatialen Referenzrahmen wie der Proband saß, was Perspektivenübernahme zur Lösung der Aufgabe obsolet machte, während sie sich in den verbleibenden Durchgängen in einem anderen visuo-spatialen Referenzrahmen befand, so dass die Probanden die visuelle Perspektive der Zielperson übernehmen mussten um die Aufgabe korrekt zu lösen. 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 Schätzfrage gestellt. Zeitgleich wurde die Antwort des Ziels bekannt gegeben. Entsprechend der Haupthypothese, dass visuo-spatiale Perspektivenübernahme psychologische Konsequenzen erzeugen kann, konnte gezeigt werden, dass die Probanden nach visuo-spatialer Perspektivenübernahme in höherem Maße die Gedanken der Zielperson übernahmen. Dies konnte sowohl anhand der absoluten Größe des Ankereffekts, als auch anhand der Differenz zwischen den Urteilen der Probanden und der Zielperson, gezeigt werden. Weitere Experimente schlossen Stichprobeneigenschaften, die verwendeten Stimuli oder die Aufgabenschwierigkeit als Alternativerklärungen für diese Effekte aus. Die beiden letzten Experimente zeigten zudem, dass dieser Effekt spezifisch für alle Konstellationen ist, in denen eine mentale Selbstrotation in die Zielperspektive notwendig war und dass die Übernahme fremder Gedanken mit einem Gefühl von Ähnlichkeit assoziiert war. Zusammengenommen unterstützen die Ergebnisse dieser Arbeit die theoretisch abgeleitete Sicht eines einheitlichen Perspektivenübernahme-Konstrukts und grenzen dieses zusätzlich von verwandten Konstrukten ab. In der abschließenden Diskussion werden die Bedeutung dieser Befunde für die Forschung in den Bereichen Empathie, Theory of Mind, und Perspektivenübernahme und ebenfalls praktische Implikationen der Ergebnisse aufgezeigt. N2 - „Perspective-taking“ is the ability to put yourself into the place of somebody else. Psychological research distinguishes three kinds of perspective-taking, namely, perceptual (visuo-spatial), affective (empathy), and cognitive (theory of mind) perspective-taking. The last two kinds of perspective-taking are often summarized as “psychological perspective-taking”. This dissertation tackles the question of whether these three kinds of perspective-taking should be conceptualized as independent constructs or as facets of one and the same construct. Prior research findings concerning this are equivocal. While some authors consider correlations between the different kinds of perspective-taking as too low for a unitary construct, others interpret correlations of the same magnitude as evidence for this. A less arbitrary way of deciding this would be to identify common mechanisms that underlie all kinds of perspective-taking and to examine whether manipulating these mechanisms in psychological experiments affects measures of perceptual, affective, and cognitive perspective-taking in parallel. In accordance with this reasoning, the present dissertation assumes that the mental self-rotation of the body schema into the physical location of another person, the main mechanism of perceptual perspective-taking, is a common mechanism of all kinds of perspective-taking. Thus, contrary to previous research a unitary construct is not only justified on the grounds of a common central functionality of all kinds of perspective-taking, that is, overcoming one’s egocentrism in favor of an alternative (perceptual, affective or cognitive) point of view, but additionally on the grounds of a common psychological mechanism. From this, the simple hypothesis that inducing visuo-spatial perspective-taking also leads to psychological consequences is derived. This hypothesis was tested in 6 experiments. In these experiments, participants first had to adopt the visual perspective of another person. To this end, they saw a person sitting at a table with two objects. During every trial, participants had to decide which hand the person would have to use in order to grab one of the two objects. Furthermore, the angular disparity between the participant and the target was manipulated in such a way that during half of the trials the target person was within the same visuo-spatial reference frame as the participant and thus no perspective-taking was necessary to solve the task correctly. During the remaining trials, the target person was sitting in another visuo-spatial reference frame so that the participants had to engage in perspective-taking to solve the task correctly. After every such trial, the target person was imbued with a mental state. This was done using an adapted paradigm for the investigation of the anchoring heuristic. Specifically, participants were asked to answer a trivia question and also saw what the target person from the visuo-spatial perspective-taking task was guessing. In line with the hypothesis that visuo-spatial perspective-taking leads to psychological outcomes, too, it was found that participants adopted the thoughts of the target person more strongly after visuo-spatial perspective-taking. This was evident in the absolute size of the anchoring effect, as well as the differences between participant and target estimations. Further experiments ruled out sample and stimulus characteristics and task difficulty as alternative explanations for these effects. The last two experiments furthermore established that the effects were specific to constellations where an embodied self-rotation into the target’s perspective was necessary and that the adoption of the target’s thoughts was associated with feelings of similarity. Taken together, these findings support the theoretically elaborated unitary view of perspective-taking and furthermore distinguish this construct from other related phenomena. In the general discussion, the significance of these findings for research on empathy, theory of mind, and perspective-taking, as well as practical implications are discussed.

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.

To facilitate home use of BCIs a multifunctional P300 BCI with a graphical user interface intended for non-expert set-up and control was designed and implemented. The system includes applications for spelling, web access, entertainment, artistic expression and environmental control. In addition to new software, it also includes new hardware for the recording of electroencephalogram (EEG) signals. The EEG system consists of a small and wireless amplifier attached to a cap that can be equipped with gel-based or dry contact electrodes. The system was systematically evaluated with a healthy sample, and targeted end users of BCI technology, i.e., people with a varying degree of motor impairment tested the BCI in a series of individual case studies. Usability was assessed in terms of effectiveness, efficiency and satisfaction. Feedback of users was gathered with structured questionnaires. Two groups of healthy participants completed an experimental protocol with the gel-based and the dry contact electrodes (N = 10 each). The results demonstrated that all healthy participants gained control over the system and achieved satisfactory to high accuracies with both gel-based and dry electrodes (average error rates of 6 and 13%). Average satisfaction ratings were high, but certain aspects of the system such as the wearing comfort of the dry electrodes and design of the cap, and speed (in both groups) were criticized by some participants. Six potential end users tested the system during supervised sessions. The achieved accuracies varied greatly from no control to high control with accuracies comparable to that of healthy volunteers. Satisfaction ratings of the two end-users that gained control of the system were lower as compared to healthy participants. The advantages and disadvantages of the BCI and its applications are discussed and suggestions are presented for improvements to pave the way for user friendly BCIs intended to be used as assistive technology by persons with severe paralysis.

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. N2 - Ziel der vorliegenden Arbeit war es, Informationen über das Vorkommen von Fahrten unter Substanzeinfluss in Deutschland und über Prädiktoren für das Auftreten von Drogenfahrten bereitzustellen. Des Weiteren wird ein neuer methodischer Ansatz vorgestellt, mit dem sowohl Daten über den Konsum psychoaktiver Substanzen als auch Daten über das Mobilitätsverhalten von Drogenkonsumenten erhoben und somit verknüpft werden können. Ein herkömmlicher Ansatz zur Schätzung des Vorkommens von Drogenfahrten sind Roadside Surveys. Als alternative Methode wird eine Studie beschrieben, in der 195 Drogenkonsumenten (vorwiegend Cannabiskonsumenten) sowie 100 Kontrollpersonen vier Wochen lang täglich über ein Smartphone ihr Fahr- und Konsumverhalten protokollierten. Aus der Häufigkeit von Drogenfahrten innerhalb der Stichprobe wird über eine entsprechende Gewichtung auf den tatsächlichen Anteil in der Bevölkerung geschlossen. Da von den Probanden sämtliche Aktivitäten im Erhebungszeitraum protokolliert wurden, können auch solche Situationen beschrieben werden, in denen sich die Probanden gegen eine Drogenfahrt entschieden haben. Darüber hinaus wurden Informationen über die persönliche Vorgeschichte, relevante Einstellungen, die Akzeptanz gesetzlicher Regelungen, weitere verkehrsrelevante Auffälligkeiten, soziale Einflüsse sowie Informationen über Persönlichkeitsmerkmale eingeholt. Hierdurch können Umstände und Hintergründe, unter denen Drogenfahrten stattfinden, spezifiziert werden. Die Ergebnisse werden in ein Model integriert, das Abhängigkeiten zwischen gesellschaftlichen Variablen, Verhaltensparametern und gesetzlichen Gegebenheiten aufzeigt. Die Studie liefert aufschlussreiche Befunde, die sowohl die wissenschaftliche Diskussion um Drogenfahrten anregen als auch von praktischem Nutzen für Rehabilitations- und Präventionsmaßnahmen sein können. Die Ergebnisse lassen sich wie folgt zusammenfassen: - Verglichen mit den Ergebnissen einer deutschen Roadside Survey aus dem Jahr 1994 fallen die hier kalkulierten Prävalenzen für Drogenfahrten in Deutschland recht gering aus. Der Befund wird diskutiert und es werden mögliche Gründe für den beschriebenen Trend aufgeführt. Außerdem werden die berechneten Werte mit aktuellen Vergleichsdaten aus anderen europäischen Ländern verglichen. - Der Konsum von Drogen hat gewisse Auswirkungen auf die Gestaltung des Alltags einer Person. Insgesamt scheinen Kontrollpersonen im Vergleich zu Drogenkonsumenten eher einem geregelten Arbeitsalltag nachzugehen (z. B. weniger Mobilität in der Nacht, mehr Mobilität zu Zeiten des allgemeinen Berufsverkehrs, Alkoholkonsum reduziert auf Ausgehzeiten). - Das Ausmaß des individuellen Drogenkonsums variiert in Abhängigkeit von Tageszeit, Wochentag und Art der Substanz. Natürlich wirken sich diese Abhängigkeiten ebenso auf das Auftreten von Drogenfahrten aus. Weitere situative Einflussfaktoren für Drogenfahrten sind die Länge der zurückzulegenden Strecke, die Verfügbarkeit alternativer Fortbewegungsmittel sowie weibliche Begleitpersonen. - Nicht jeder, der Drogen konsumiert, fährt auch unter Drogeneinfluss Auto. Als wesentlicher Prädiktor für häufige Drogenfahrten und hohe Substanzkonzentrationen im Blut während der Fahrt kann ein hoher Konsum genannt werden. Damit verbunden sind riskante Konsummuster sowie eine geringe subjektive Beeinträchtigung nach dem Konsum von Drogen. - Die Einstellung der Versuchspersonen zu Drogenfahrten sowie ihre Annahmen über soziale Normen stimmen zum großen Teil mit ihrem Verhalten überein. Drogenkonsumenten haben eher liberale Einstellungen zu Drogenkonsum und Drogenfahrten. - Eine mögliche abschreckende Wirkung von Sanktionen und polizeilichen Überwachungmaßnahmen und ihre Abhängigkeit von der Akzeptanz und der subjektiven Wahrnehmung der Maßnahmen wird beschrieben. - Eine objektive Leistungsbeeinträchtigung durch die Wirkung von Drogen mittels einer computerbasierten Testbatterie kann nur in geringem Maße nachgewiesen werden. Das Ergebnis wird hinsichtlich der Operationalisierung der untersuchten Gruppen kritisch diskutiert. - Es finden sich keine Hinweise dafür, dass Drogenfahrer, außer durch die Drogenfahrten an sich, auch sonst im Verkehr auffällig werden. - Eltern und Freunde scheinen als Rollenvorbilder Einfluss auf die Entwicklung von Problemverhalten zu nehmen. Eine gute Eltern-Kind-Beziehung wirkt sich positiv auf die Entwicklung konventioneller Werte und Verhalten aus. - Drogenkonsum ist mit einigen wesentlichen Persönlichkeitsmerkmalen assoziiert und Konsumenten weisen etwas häufiger psychische Probleme auf als Kontrollpersonen. Abschließend werden Stärken und Schwächen der neuen Methode diskutiert sowie besondere Anforderungen aufgeführt, die bei der Durchführung zu beachten sind. Insgesamt erwies sich die Methode als vielversprechend und sollte als Standard in künftigen Studien weiterentwickelt werden.

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.

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

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.

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

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