Impulsive and premeditated subtypes of aggression in conduct disorder: differences in time estimation

Research aimed at identifying and studying subtypes of aggression have historically dichotomized aggressive subtypes, although specific nomenclature has varied; one approach has been to classify aggressive behavior as predominantly impulsive or predominantly premeditated. There are a number of behavioral and cognitive differences between those exhibiting these different forms of aggression. This study was designed to extend understanding of the impulsive/premeditated aggression dichotomy by comparing time estimation among adolescents exhibiting predominantly impulsive or predominantly premeditated forms of physical aggression who have a psychiatric diagnosis of conduct disorder (CD). Time estimation has previously been shown to be disrupted in impulsive and some aggressive individuals. Time estimation was compared between healthy Controls (n = 37) and two groups of adolescents with CD, those with histories of either predominantly impulsive (CD-Impulsive, n = 26) or predominantly premeditated (CD-Premeditated, n = 38) aggressive behaviors. Participants completed five computerized trials during which they estimated when 1 min had passed. Among aggressive adolescents with CD, the misperception of time was specific to those with histories of impulsive aggression, although time estimates improved with repeated testing and performance feedback. This study confirms the importance of considering the role and type of physical aggression when studying heterogeneous diagnostic groups like CD and supports the relevance of time estimation to certain subgroups of adolescents with CD.

Bindungsforschung und therapeutische Beziehung

Zusammenfassung Die von John Bowlby konzipierte Bindungstheorie postuliert ein primäres Bedürfnis nach Bindung und Nähe zu versorgenden Personen, das in der frühen Kindheit zur Ausbildung innerer Repräsentanzen/Arbeitsmodelle von Bindung und Bindungserfahrungen führt, in die sowohl Aspekte des Selbstkonzeptes als auch Konzepte über die Reaktionen relevanter Anderer integriert werden. Die entwicklungspsychologische Forschung hat in den vergangenen Jahrzehnten ein tragfähiges empirisches Fundament für die Bindungstheorie geliefert und mit dazu beigetragen, dass die Theorie auch im klinischen Kontext zunehmend reflektiert wird. Die therapeutische Beziehung kann aus bindungstheoretischer Sicht zumindest unter bestimmten Umständen als eine spezifische Form einer Bindungsbeziehung erachtet werden. Ein derartiges Modell hat in jüngster Vergangenheit zu einer Vielzahl theoretischer Überlegungen über die Qualität der therapeutischen Beziehung aus bindungstheoretischer Sicht geführt. Neben theoretischen Beiträgen zur Thematik gibt es mittlerweile auch eine immer größer werdende Zahl empirischer Untersuchungen, die sich mit der Relevanz bindungstheoretischer Konstrukte für den Therapieerfolg, den therapeutischen Prozess und die therapeutische Allianz beschäftigen. Eine Zusammenfassung dieser Studien zeigt, dass es für Psychotherapeuten lohnend sein kann, sich mit den Konzepten der Theorie näher zu beschäftigen, beispielsweise um Brüche und Schwierigkeiten in der therapeutischen Beziehung besser zu verstehen und ggf. verhindern zu können.Eine modifizierte Version dieser Übersicht wird erscheinen in: Hermer M, Röhrle B (Hrsg) (2006) Handbuch der therapeutischen Beziehung – Beziehungsgestaltung, Bündnisprobleme, Kontexte. dgvt, Tübingen.

Adaptation to a direction-dependent visuomotor gain in the young and elderly

Consistent with the widely accepted notion of separate specification of movement amplitude and direction, it has been argued that there is also a categorical difference between adaptation to novel visuomotor rotations and to novel visuomotor gains. In line with this view, ageing seems to affect rotation and gain adaptation differently in that age-related impairments are consistently found for the former, but not for the latter. In this study we ask whether the contrasting findings could also be ascribed to differences in the level of difficulty of gain and rotation adaptation tasks, respectively. In order to increase the difficulty of gain adaptation, younger and older participants had to adapt to a direction-dependent gain transformation. Results revealed direction-dependent adaptation in both groups. More importantly, we replicated the typical findings of age-related impairments of adaptation, but not of aftereffects, that were previously only reported for rotation adaptation. Younger participants also showed superior explicit knowledge regarding the novel visuomotor mapping as compared to the older participants. We show that this knowledge was used by younger participants to selectively augment adaptive shifts. Finally, our findings suggest that the difficulty of the novel visuomotor transformation and, related to this, the involvement of explicit knowledge in adaptation is critical for age-related changes to show up, but not the type of adaptation task, rotation and gain adaptation, respectively.     

Social relations and presence of others predict bystander intervention: Evidence from violent incidents captured on CCTV

Are individuals willing to intervene in public violence? Half a century of research on the “bystander effect” suggests that the more bystanders present at an emergency, the less likely each of them is to provide help. However, recent meta-analytical evidence questions whether this effect generalizes to violent emergencies. Besides the number of bystanders present, an alternative line of research suggests that pre-existing social relations between bystanders and conflict participants are important for explaining whether bystanders provide help. The current paper offers a rare comparison of both factors—social relations and the number of bystanders present—as predictors of bystander intervention in real-life violent emergencies. We systematically observed the behavior of 764 bystanders across 81 violent incidents recorded by surveillance cameras in Copenhagen, Denmark. Bystanders were sampled with a case–control design, their behavior was observed and coded, and the probability of intervention was estimated with multilevel regression analyses. The results confirm our predicted association between social relations and intervention. However, rather than the expected reversed bystander effect, we found a classical bystander effect, as bystanders were less likely to intervene with increasing bystander presence. The effect of social relations on intervention was larger in magnitude than the effect of the number of bystanders. We assess these findings in light of recent discussions about the influence of group size and social relations in human helping. Further, we discuss the utility of video data for the assessment of real-life bystander behavior.
