Predicting post-event processing in social anxiety disorder following two prototypical social situations: State variables and dispositional determinants

This study investigated self-reported state (anxiety, physical symptoms, cognitions, internally focused attention, safety behaviors, social performance) and trait (social anxiety, depressive symptoms, dysfunctional self-consciousness) predictors of post-event processing (PEP) subsequent to two social situations (interaction, speech) in participants with a primary diagnosis of social anxiety disorder (SAD) and healthy controls (HC). The speech triggered significantly more intense PEP, especially in SAD. Regardless of the type of social situation, PEP was best predicted by situational anxiety and dysfunctional cognitions among the state variables. If only trait variables were considered, PEP following both situations was accounted for by trait social anxiety. In addition, dysfunctional self-consciousness contributed to PEP-speech. If state and trait variables were jointly considered, for both situations, situational anxiety and dysfunctional cognitions were confirmed as the most powerful PEP predictors above and beyond trait social anxiety (interaction) and dysfunctional self-consciousness (speech). Hence, PEP as assessed on the day after a social situation seems to be mainly determined by state variables. Trait social anxiety and dysfunctional self-consciousness also significantly contribute to PEP depending on the type of social situation. The present findings support dysfunctional cognitions as a core cognitive mechanism for the maintenance of SAD. Implications for treatment are discussed.     

Face Emotion Processing in Depressed Children and Adolescents with and without Comorbid Conduct Disorder

Studies of adults with depression point to characteristic neurocognitive deficits, including differences in processing facial expressions. Few studies have examined face processing in juvenile depression, or taken account of other comorbid disorders. Three groups were compared: depressed children and adolescents with conduct disorder (n = 23), depressed children and adolescents without conduct disorder (n = 29) and children and adolescents without disorder (n = 37). A novel face emotion processing experiment presented faces with ‘happy’, ‘sad’, ‘angry’, or ‘fearful’ expressions of varying emotional intensity using morphed stimuli. Those with depression showed no overall or specific deficits in facial expression recognition accuracy. Instead, they showed biases affecting processing of low-intensity expressions, more often perceiving these as sad. In contrast, non-depressed controls more often misperceived low intensity negative emotions as happy. There were no differences between depressed children and adolescents with and without conduct disorder, or between children with comorbid depression/conduct disorder and controls. Face emotion processing biases rather than deficits appear to distinguish depressed from non-depressed children and adolescents.     

Can clouds dance? Neural correlates of passive conceptual expansion using a metaphor processing task: Implications for creative cognition

Creativity has emerged in the focus of neurocognitive research in the past decade. However, a heterogeneous pattern of brain areas has been implicated as underpinning the neural correlates of creativity. One explanation for these divergent findings lies in the fact that creativity is not usually investigated in terms of its many underlying cognitive processes. The present fMRI study focuses on the neural correlates of conceptual expansion, a central component of all creative processes. The study aims to avoid pitfalls of previous fMRI studies on creativity by employing a novel paradigm. Participants were presented with phrases and made judgments regarding both the unusualness and the appropriateness of the stimuli, corresponding to the two defining criteria of creativity. According to their respective evaluation, three subject-determined experimental conditions were obtained. Phrases judged as both unusual and appropriate were classified as indicating conceptual expansion in participants. The findings reveal the involvement of frontal and temporal regions when engaging in passive conceptual expansion as opposed to the information processing of mere unusualness (novelty) or appropriateness (relevance). Taking this new experimental approach to uncover specific processes involved in creative cognition revealed that frontal and temporal regions known to be involved in semantic cognition and relational reasoning play a role in passive conceptual expansion. Adopting a different vantage point on the investigation of creativity would allow for critical advances in future research on this topic.     

The More the Better? Effects of Training,Experience and Information Amount in Legal Judgments

In an experimental study involving German lay judges, law students and controls, effects of legal training and experience as well as information amount on legal judgments was investigated. In a three (legal knowledge: legal training versus legal experience versus controls) x two (information amount: high versus low) between‐subjects design, 137 participants judged the premeditation of a perpetrator in eight real‐world cases decided by the German Federal Court of Justice. Judgment congruency with the Court's ruling increased with legal training, but official lay judges showed lower congruency compared with student controls. Additionally, legal training and experience corresponded with higher confidence. Emotional reactions to the legal cases were stronger when more information was given for individuals without legal training but decreased for individuals with training. An information‐processing perspective to explain the observed differences in legal judgments is advanced, and the issue of using untrained individuals in the legal decision making process is discussed.

Independence of data-driven and conceptually driven priming: the case of person recognition

A central tenet of current memory theories is the independence of data-driven and conceptually driven priming. Although these types of repetition priming have different functional properties, it has remained unclear whether they are independent and additive or interact with each other. Therefore, we orthogonally combined these priming types in two experiments requiring occupation judgments for celebrities, represented by their faces or names. In both experiments, the sum of the effects of separate data-driven priming and conceptually driven priming equaled the effect of the combination of these priming types. These findings demonstrate for the first time the independence of data-driven and conceptually driven priming and so confirm a central tenet of current memory theories. This independence may thus be an important element for the development of future overarching memory theories.     

Neurobiologische Grundlagen psychotherapeutischer Verfahren

In the last few years the investigation of the neurobiological basis of psychotherapeutic treatments has gained importance. Therapy-associated functional changes have been studied in a number of different psychiatric diseases. It has been shown that diseases with a central role of emotions (e.g. depression, anxiety disorders, borderline personality disorder) often demonstrate dysfunctions in brain areas that are linked to emotional regulation. Psychotherapeutic interventions can lead to a kind of normalization of brain responses in these areas (e.g. amygdala, ventromedial prefrontal cortex, anterior cingulate cortex, orbitofrontal cortex). In addition, therapy-associated transformations were also demonstrated in areas which are related to attention processes and visual perception. Other studies have aimed at finding neurobiological parameters that can be used to predict a therapeutic outcome or to choose between various therapeutic strategies. For instance, in depression, the amygdala and the anterior cingulate cortex are assumed to play a major role. Altogether, knowledge on the neurobiological basis of psychotherapeutic procedures is limited. A comparatively small number of studies and several methodological problems (e.g. small sample sizes, insufficient control groups, variability of methods used) make it difficult to propose reliable statements.     

Brain oscillatory activity associated with task switching and feedback processing

In this study, we sought to dissociate event-related potentials (ERPs) and the oscillatory activity associated with signals indicating feedback about performance (outcome-based behavioral adjustment) and the signals indicating the need to change or maintain a task set (rule-based behavioral adjustment). With this purpose in mind, we noninvasively recorded electroencephalographic signals, using a modified version of the Wisconsin card sorting task, in which feedback processing and task switching could be studied separately. A similar late positive component was observed for the switch and correct feedback signals on the first trials of a series, but feedback-related negativity was observed only for incorrect feedback. Moreover, whereas theta power showed a significant increase after a switch cue and after the first positive feedback of a new series, a selective frontal beta–gamma increase was observed exclusively in the first positive feedback (i.e., after the selection of the new rule). Importantly, for the switch cue, beta–alpha activity was suppressed rather than increased. This clear dissociation between the cue and feedback stimuli in task switching emphasizes the need to accurately study brain oscillatory activity to disentangle the role of different cognitive control processes.     

The role of action and coping planning in the relationship between intention and physical activity: A moderated mediation analysis

Objective: Using a moderated mediation model, the present study investigated whether the mediation of intention into physical activity (PA) behaviour via action planning depends on the level of coping planning.

Method: A four-month prospective study was conducted among 157 French adults, who were recruited through a web-based survey. They were administrated measures of behavioural intention and sociodemographic variables at baseline and action and coping planning and PA four months later.

Results: Action planning partially mediated the contribution of intention on PA level. However, this indirect effect was conditional on the level of coping planning, insofar as action planning acted as a mediator of the intention–PA relationship only for individuals with high level of coping planning.

Conclusion: The results highlight the complexity of the relationship between intention and behaviour and provide evidence for the distinct role of both forms of planning.     

The effect of rebranding generic medicines on drug efficacy and side effects

Objectives: Subjective age is an important correlate of health, well-being, and longevity. So far, little is known about short-term variability in subjective age and the circumstances under which individuals feel younger/older in daily life. This study examined whether (a) older adults’ felt age fluctuates on a day-to-day basis, (b) daily changes in health, stressors, and affect explain fluctuations in felt age, and (c) the daily associations between felt age and health, stressors, or affect are time-ordered.

Method: Using an eight-day daily diary approach, N = 43 adults (60–96 years, M = 74.65, SD = 8.19) filled out daily questionnaires assessing subjective age, health, daily stressors, and affect. Data were analysed using multilevel modelling.

Main outcome measures: Subjective age, health, daily stressors, affect.

Results: Intra-individual variability in felt age was not explained by time but by short-term variability in other variables. Specifically, on days when participants experienced more than average health problems, stress, or negative affect they felt older than on days with average health, stress, or negative affect. No time-ordered effects were found.

Conclusion: Bad health, many stressors, and negative affective experiences constitute circumstances under which older adults feel older than they typically do. Thus, daily measures of subjective age could be markers of health and well-being.
