Speeded detection and increased distraction in fear of spiders: evidence from eye movements

Anxiety patients exhibit attentional biases toward threat, which have often been demonstrated as increased distractibility by threatening stimuli. In contrast, speeded detection of threat has rarely been shown. Therefore, the authors studied both phenomena in 3 versions of a visual search task while eye movements were recorded continuously. Spider-fearful individuals and nonanxious control participants participated in a target search task, an odd-one-out search task, and a category search task. Evidence for disorder-specific increased distraction by threat was found in all tasks, whereas speeded threat detection did not occur in the target search task. The implications of these findings for cognitive theories of anxiety are discussed, particularly in relation to the concept of disengagement from threat.     

Forced choice reaction time paradigm in children with separation anxiety disorder, social phobia, and nonanxious controls

Cognitive distortions refer to cognitive processes that are biased and therefore yield dysfunctional and maladaptive products (e.g., interpretation bias). Automatic aspects of information processing need to be considered and investigating these aspects requires forms of assessment other than self-report. Studies focussing on the specificity of cognitive biases across different types of anxiety disorders in childhood are rare. Thus, a forced choice reaction time paradigm with picture stimuli was used to assess the interpretation bias in anxious children online. The study investigated disorder-specific interpretation bias in 71 children with separation anxiety disorder (SAD), 31 children with social phobia, and 42 children without mental disorders, aged 5–13 years. Results indicated that children with SAD rated ambiguous separation pictures as significantly more unpleasant and more arousing than nonanxious children. However, no support was found that children with SAD and social phobia interpret ambiguous separation or social pictures in a more negative way than nonanxious children. Furthermore, no group differences were found in reaction times to all picture categories.     

Whose “Storm and Stress” Is It? Parent and Child Reports of Personality Development in the Transition to Early Adolescence

The present study investigated Big Five personality trait development in the transition to early adolescence (from the fifth to eighth grade). Personality traits were assessed in 2,761 (47% female) students over a 3‐year period of time. Youths’ self‐reports and parent ratings were used to test for cross‐informant agreement. Acquiescent responding and measurement invariance were established with latent variable modeling. Growth curve models revealed three main findings: (a) Normative mean‐level changes occurred for youths’ self‐report data and parent ratings with modest effects in both cases. (b) Agreeableness and Openness decreased for self‐reports and parent ratings, whereas data source differences were found for Conscientiousness (decreased for self‐reports and remained stable for parent ratings), Extraversion (increased for self‐reports and decreased for parent ratings), and Neuroticism (remained stable for self‐reports and decreased for parent ratings). (c) Girls showed a more mature personality overall (self‐reports and parent ratings revealed higher levels of Agreeableness, Conscientiousness, and Openness) and became more extraverted in the middle of adolescence (self‐reports). Personality changes modestly during early adolescence whereby change does not occur in the direction of maturation, and substantial differences exist between parent ratings and self‐reports.     

Independent effects of temporal expectation and stimulus intensity in audition

Temporal orienting—that is, selective attention to instants in time—has been shown to modulate performance in terms of faster responses in a variety of paradigms. Electrophysiological recordings have shown that temporal orienting modulates neural processing at early, probably perceptual, and late, probably decision- or response-related, stages. Recently, it was shown that the effect of temporal orienting on early auditory brain potentials is independent of the effect of the physical sound feature intensity. This indicates that temporal orienting might not affect stimulus processing by increasing the sensory gain of attended stimuli. In the present study, we investigated whether the independence of temporal-orienting and sound-intensity effects could be replicated behaviorally. Sequences were presented that were either rhythmic, most likely creating temporal expectations, or arrhythmic, presumably not creating such expectations. As hypothesized, the main effects of temporal expectation and sound intensity on reaction times were independent (Experiment 1). The exact pattern of results was replicated with a slightly altered paradigm (Experiment 2) and with a different kind of task (Experiment 3). In sum, these results corroborate the notion that the effect of temporal orienting might not rely on the same processes as the effect of sound intensity does.     

Gender constructions from a project on sex offenders

Abstract

The four-year group therapy of 16 sex offenders in prison was videotaped, and 21 sessions were carefully transcribed and analysed by means of conversation analysis and analysis of metaphor and narration. These qualitative methods are apt for verbal data and can be combined with psychoanalytic thinking in a productive way. New forms of process analysis can be developed. The results presented here are selected to relate to the topic of how the imprisoned group therapy participants constructed “gender” by ways of speaking about themselves, women, and their victims, young girls. The results show that it would be a mistake to think of these ways of speaking as if they could be ignored in favour of “deeper” motives, lying “behind” the words. Our results show how unconscious constructions of gender are not beyond language, but in language. “Doing gender” is a conversational practice.     

Depression in early adolescence: Contributions from relational aggression and variation in the oxytocin receptor gene

Interpersonal stress arising from relational aggression (RA)—the intentional effort to harm others via rejection and exclusion—may increase risk for depression in youth. Biological vulnerabilities related to the hormone oxytocin, which affects social behavior and stress responses, may exacerbate this risk. In a community sample of 307 youth (52% female; age range = 10–14 years), we tested whether (1) the association between RA and subsequent depressive symptoms was mediated through social problems and (2) a single nucleotide polymorphism (rs53576) in the oxytocin receptor gene (OXTR) moderated this indirect association between RA and depression, where GG homozygotes are predicted to be more sensitive to the effects of social problems than A‐allele carriers. Youth‐reported RA and depressive symptoms were measured using a structured interview and a questionnaire, respectively. DNA was extracted from saliva collected with Oragene kits. Consistent with the interpersonal theory of depression, the association between relational aggression and subsequent depressive symptoms was mediated by social problems. This indirect effect was further moderated by rs53576 genotype, such that GG homozygotes showed a stronger mediation effect than A‐carriers. These results suggest that rs53576 variants confer vulnerability for depression within the context of interpersonal risk factors, such that youth with the GG genotype may be particularly sensitive to the social consequences resulting from RA.

     

The neural correlates of reward-related trial-and-error learning: an fMRI study with a probabilistic learning task

This fMRI study investigated the neural correlates of reward-related trial-and-error learning in association with changing degrees of stimulus-outcome predictabilities. We found that decreasing predictability was associated with increasing activation in a frontoparietal network. Only maximum predictability was associated with signal decreases across the learning process. The receipt of monetary reward revealed activation in the striatum and associated frontoparietal regions. Present data indicate that during reward-related learning, high uncertainty forces areas relevant for cognitive control to remain activated. In contrast, learning on the basis of predictable stimulus-outcome associations enables the brain to reduce resources in association with the processes of prediction.
