Komplexe Traumatisierungen und körperliche Gesundheit

Trauma in childhood, which is considered to be the “prototype” of complex traumatization, is associated with numerous physical diseases, in particular with coronary artery disease (CAD). In this review we present the current state of research on this issue. Despite inconsistencies in details between reported findings, numerous studies consistently show a clear relationship between childhood maltreatment and CAD. This association holds not only for clinical endpoints, e.?g. myocardial infarct and angina pectoris but also for subclinical markers of CAD. In this article three distinct etiopathogenetic pathways are defined linking childhood maltreatment to CAD, namely mental alterations, behavioral alterations, such as harmful health behavior and pathophysiological changes including somatic comorbidities. Methodology critical aspects and future research issues as well as the clinical implications of these findings are briefly discussed.     

That’s not my place: The interacting effects of faultlines,subgroup size,and social competence on social loafing behaviour in work groups

Taking a social relations approach to team diversity, we propose that faultlines—hypothetical dividing lines that split a team into relatively homogeneous subgroups—impact the team members’ propensity to exhibit social loafing behaviour. We further propose that this individual-level reaction to the faultline structure of the team can differ among team members, depending on the size of their subgroup and on their individual social competence. We tested the assumptions with a sample of real teams working on an intellective task during which social loafing behaviour was video-coded. In partial support of the hypotheses, generalized mixed models revealed that social loafing behaviour was most common for team members who were part of a team with strong faultlines, who belonged to the larger subgroup in their team, and who exhibited low levels of social competence. The results therefore highlight the benefits of taking a multilevel approach to the effects of faultlines.     

The Price of a Piece of Cheese: Value from Fit Between Epistemic Needs and a Learning Versus an Outcome Focus

In decision making, people can focus on decisional outcomes (outcome focus), but they can also focus on gaining knowledge about the decisional domain (learning focus). Furthermore, people differ in the strength of their epistemic needs—their preference for developing a rich and accurate understanding of the world. We invoke the regulatory fit theory to predict that higher epistemic needs better fit a learning focus than lower epistemic needs, resulting in a greater increase in valuation of the chosen option when a learning rather than an outcome focus is induced. This general hypothesis was tested and supported in three studies, each focusing on a different proxy to epistemic needs. Thus, individuals experienced greater value when they had lower expertise (Study 1), higher need for assessment (Study 2), and higher need for cognition (Study 3) when a learning rather than an outcome focus was induced. Implications for work on epistemic needs, regulatory fit theory, and decision‐making practice are discussed. Copyright © 2011 John Wiley & Sons, Ltd.     

Metaphysics within Chemical Physics: The Case of Ab Initio Molecular Dynamics

This paper combines naturalized metaphysics and a philosophical reflection on a recently evolving interdisciplinary branch of quantum chemistry, ab initio molecular dynamics. Bridging the gaps among chemistry, physics, and computer science, this cutting-edge research field explores the structure and dynamics of complex molecular many-body systems through computer simulations. These simulations are allegedly crafted solely by the laws of fundamental physics, and are explicitly designed to capture nature as closely as possible. The models and algorithms employed, however, involve many approximations and significant degrees of idealization of their target systems. Therefore, for philosophers of science the pivotal question of whether relying only on the fundamental laws of physics supports a reductionist or realist stance arises. One conceivable answer to this question is that the irreducible approximations and idealizations support rather anti-realist positions. After reviewing an influential attitude in the philosophy of computer simulations and the debate concerning scientific realism, I offer a fair interpretation of such ab initio modelling in quantum chemistry within a naturalistic metaphysical framework that gives rise to a specific type of ontic structural realism.     

Emotions that associate with uncertainty lead to structured ideation

This study tested the role of emotion in structured ideation, a process in which newly generated ideas and insights closely follow previously generated ideas and insights. Emotions can be differentiated on a number of underlying dimensions, including uncertainty, and uncertainty can influence information processing. On these grounds, we proposed and tested the idea that (1) emotions that associate with appraisals of uncertainty (fear, sadness) lead to more structured ideation than emotions that associate with appraisals of certainty (happiness, anger) and that (2) appraisals of uncertainty drive this effect. Findings of four experiments on idea generation in which (un)certainty was primed (Study 1) and emotions were induced through self-generated imagery (Study 2-4) supported these predictions.

When beliefs are not enough: Examining the interaction of diversity faultlines,task motivation,and diversity beliefs on team performance

Diversity faultline strength – the extent to which diversity attributes within a group converge in such a way that they split a group into homogeneous subgroups – can decrease group performance. Based on the categorization–elaboration model (CEM) of workgroup diversity, we assumed that task motivation can overcome the detrimental effects of faultlines. We further assumed that this effect is contingent on the groups' diversity beliefs and that it is mediated by the elaboration of task-relevant information. Forty-three student groups worked on a computer-simulated complex problem solving scenario. The group faultline strength was calculated over the attributes gender, age and educational background. Information elaboration was elicited by means of behavioural coding. Results revealed a three-way interaction of faultline strength, diversity beliefs and task motivation: groups overcame the detrimental effects of faultlines only if they exhibited pro-diversity beliefs and high task motivation. The three-way interaction of faultline strength, diversity beliefs and task motivation was partly mediated by information elaboration. Practical and theoretic implications are discussed.     

The development of creative cognition across adolescence: distinct trajectories for insight and divergent thinking

We examined developmental trajectories of creative cognition across adolescence. Participants (N = 98), divided into four age groups (12/13 yrs, 15/16 yrs, 18/19 yrs, and 25–30 yrs), were subjected to a battery of tasks gauging creative insight (visual; verbal) and divergent thinking (verbal; visuo‐spatial). The two older age groups outperformed the two younger age groups on insight tasks. The 25–30‐year‐olds outperformed the two youngest age groups on the originality measure of verbal divergent thinking. No age‐group differences were observed for verbal divergent thinking fluency and flexibility. On divergent thinking in the visuo‐spatial domain, however, only 15/16‐year‐olds outperformed 12/13‐year‐olds; a model with peak performance for 15/16‐years‐old showed the best fit. The results for the different creativity processes are discussed in relation to cognitive and related neurobiological models. We conclude that mid‐adolescence is a period of not only immaturities but also of creative potentials in the visuo‐spatial domain, possibly related to developing control functions and explorative behavior.     

Between a Rock and a Hard Place: Mental Causation and the Mind-Body Problem

Marx may be taken to hold that productive forces (e.g. the steam engine) explain productive relations (e.g. capitalism) more than the other way on, and that productive relations explain superstructures (e.g. the legal system) more than the other way on. There are no satisfactory standard causal understandings of these claims about explanatory primacy. That is, no standard causal understanding saves Marx from the traditional objection that relations very greatly affect forces, and superstructures very greatly affect relations. One satisfactorily articulated attempt to save Marx has been the attempt to understand the claims teleologically. Three such understandings can be distinguished, but they do not work. The first fails since it attempts to explain events by way of abstract objects. The second fails since it attempts to explain a thing by means of that thing. The third fails for a related reason. Each understanding also fails for another reason as fundamental. So‐called teleological explanations are in fact claims that standard causal explanations exist, which relevant explanations conflict with the ruling idea of Marx's philosophy, that history is somehow independent of men's consciousness and wills. There may be no evidence that Marx himself intended historical materialism to be understood teleologically. There may be evidence against.
