Gender Differences in Biobehavioral Aftereffects of Stress on Eating,Frustration, and Cardiovascular Responses1

Eating, persistence, and cardiovascular responses were evaluated after exposure to a 25‐min noise stressor with or without perceived control. Participants were healthy men (n = 29) and women (n = 34), aged 21 to 45 years. There were no group differences in cognitive task performance or blood pressure during the stressor. However, perceived control resulted in lower mean blood pressure and heart rate after cessation of the stressor for men and women. Women without perceived control displayed greater frustration levels following the stressor, and frustrated women ate more bland food than did nonfrustrated women. Perceived control and frustration did not affect food consumption among men following the stressor. These findings indicate that there are health‐relevant gender differences in biobehavioral responses that occur in the aftermath of stressor exposure. In addition, perceived control was especially important for women to attenuate the behavioral and biological effects of stressor exposure.     

Inter‐category versus intra‐category fit: when social categories match social context

The goal of the research reported in this article was to examine whether social categorization, commonly thought to be a function of accessibility and intra‐category fit, is also sensitive to changes in inter‐category fit. Intra‐category fit refers to the match between a target person's features and stored categorical knowledge, inter‐category fit to the extent to which category memberships and targets' features covary across perceived group members. In Experiments 1, 2, and 3, members of social categories of low, medium, and high accessibility, respectively, were shown in a group discussion. Inter‐category fit was manipulated in three steps. Category salience in memory increased as an additive function of accessibility and inter‐category fit. Experiment 4 replicated the effects of inter‐category fit while intra‐category fit and the information presented for individual discussants were held constant. The present studies are the first to demonstrate an effect of inter‐category fit on a relatively direct measure of spontaneous social categorization. Copyright © 2004 John Wiley & Sons, Ltd.     

Peer victimization and social anxiety in adolescence: a prospective study

This study reports a one‐year prospective investigation of the relations between overt and relational victimization and social anxiety and phobia in a sample of adolescents. The Social Experience Questionnaire—Self Report Form (SEQ‐S), Social Anxiety Scale for Adolescents (SAS‐A), and Social Phobia and Anxiety Inventory for Children (SPAI‐C) were administered to 144 ninth grade adolescents. A follow‐up assessment with the SEQ‐S, SAS‐A, and SPAI‐C was conducted one year later. Results indicated that relational victimization predicted symptoms of social phobia but not general social anxiety and avoidance one year later. Overt victimization was not a significant predictor of social anxiety and phobia one year later. Social anxiety and phobia did not predict peer victimization one year later. However, increases in social anxiety and social phobia symptoms (for boys) over time were positively associated with increases in relational victimization over time. Implications of these findings for peer victimization and social anxiety in the development of social phobia and negative peer experiences are discussed. Aggr.

Social categorization and fit detection under cognitive load: efficient or effortful?

Participants perceived a discussion between members of two social categories in a name‐matching paradigm. Discussions either exhibited inter‐category fit, defined as a covariation of category membership and the category members' attitude positions, or not. Orthogonally, there was cognitive load at encoding, load at retrieval, or no concurrent load. Memory for the statements and memory for the speaker of a statement were affected by load with little evidence for fit effects. Conversely, category memory, reconstructive category guessing and perceived fit were affected by inter‐category fit with little evidence for load effects. The results suggest that category activation is sensitive to inter‐category fit and that fit detection is robust against moderate amounts of cognitive load.

Psychotherapie bei Patienten mit koronarer Herzkrankheit

Psychosomatisch-somatopsychische Interaktionen sind bei Koronarpatienten häufig und verlaufsrelevant. Seit den 1960er-Jahren kommen daher psychosoziale Interventionen zur Verbesserung von Befinden und Krankheitsverlauf zum Einsatz. Neben psychoedukativen und unspezifisch-supportiven Angeboten oder Entspannungsverfahren finden sich auch explizit psychotherapeutische Interventionen. Diese beabsichtigen einerseits, durch Reduktion von Stressbelastungen und Förderung gesundheitsbewusster Verhaltensweisen den Krankheitsverlauf zu verlangsamen. Zuletzt wurde zudem auch die Psychotherapie psychischer Komorbiditäten untersucht. Hier spielt die prognostisch relevante Depression eine besondere Rolle. In der größten Psychotherapiestudie bei Koronarpatienten, der ENRICHD-Studie, wurde bei 2481 Infarktpatienten mit Depression oder mangelnder sozialer Unterstützung eine maximal halbjährige kognitive Verhaltenstherapie eingesetzt. Diese führte zur deutlichen Besserung der Depressivität; bei hoher Spontanremissionsrate in der Kontrollgruppe blieb der Nettoeffekt jedoch bescheiden. Eine Lebensverlängerung wurde in der Interventionsgruppe nicht erreicht. Die Befundlage verlangt differenzielle Indikationsstellungen und behandlungstechnische Weiterentwicklungen der therapeutischen Konzepte bzw. die Erprobung anderer Therapieverfahren, erlaubt jedoch noch keine evidenzbasierte allgemeine Behandlungsempfehlung. Therapieentscheidungen stützen sich heute auf die Würdigung des Einzelfalls, auf gut belegte subjektiven Therapieeffekte, theoretische Annahmen über Stressbewältigungs- und Entspannungsverfahren sowie die an anderen Patientenkollektiven gewonnenen Wirksamkeitsnachweise psychotherapeutischer Verfahren. Dabei sind generell eine Beachtung der kardialen Situation und der typischen Problembereiche der koronaren Herzkrankheit (KHK) sowie eine gute Abstimmung mit den somatischen Behandlern wichtig.

The association between attention control,anxiety, and depression: the indirect effects of repetitive negative thinking and mood recovery

Background and objectives: Attention control deficits and repetitive negative thinking (RNT; i.e., rumination) may be key factors in the development and persistence of depression and anxiety, although their role in symptom development remains poorly understood. This represents a gap in the literature, as interventions targeting attention control and associated RNT may enhance interventions and prevent costly relapse. The current study was designed to examine the serial indirect effects of transdiagnostic RNT and negative affect recovery following a lab-induced stressor on the association between attention control deficits and trait anxiety and depression.

Methods: Participants were N?=?583 university students who completed validated measures of RNT, anxiety, depression, and mood ratings pre- and post-stressor. Stress was induced using a modified version of the Trier Social Stress Test.

Results: Results of cross-sectional indirect effects models indicated that RNT and mood recovery explained the association between attention control deficits and trait anxiety and depression. Results from reversed models indicated that only the indirect effect of RNT was significant.

Conclusions: Findings suggest that RNT and mood recovery processes play an important role in explaining anxiety and depression symptoms. Additional work is needed to examine their role in symptom development and maintenance over time.     

Children's initial sleep‐associated changes in motor skill are unrelated to long‐term skill levels

Sleep is considered to support the formation of skill memory. In juvenile but not adult song birds learning a tutor's song, a stronger initial deterioration of song performance over night‐sleep predicts better song performance in the long run. This and similar observations have stimulated the view of sleep supporting skill formation during development in an unsupervised off‐line learning process that, in the absence of external feedback, can initially also enhance inaccuracies in skill performance. Here we explored whether in children learning a motor sequence task, as in song‐learning juvenile birds, changes across sleep after initial practice predict performance levels achieved in the long run. The task was a serial reaction time task (SRTT) where subjects had to press buttons which were lighted up in a repeating eight‐element sequence as fast as possible. Twenty‐five children (8–12 years) practised the task in the evening before nocturnal sleep which was recorded polysomnographically. Retrieval was tested on the following morning and again 1 week later after daily training on the SRTT. As expected, changes in response speed over the initial night of sleep were negatively correlated with final performance speed after the 1‐week training. However, unlike in song birds, this correlation was driven by the baseline speed level achieved before sleep. Baseline‐corrected changes in speed or variability over the initial sleep period did not predict final performance on the trained SRTT sequence, or on different sequences introduced to assess generalization of the trained behaviour. The lack of correlation between initial sleep‐dependent changes and long‐term performance might reflect that the children were too experienced for the simple SRTT, possibly also favouring ceiling effects in performance. A consistent association found between sleep spindle activity and explicit sequence knowledge alternatively suggests that the expected correlation was masked by explicit memory systems interacting with skill memory formation.
