Recalibration of the convergence system.

Adaptation to convergence-altering prism spectacles was studied. The subjects were trained for 8 min with either convergence-increasing or convergence-decreasing prisms. Before and after training they estimated the distance to a binocular dot varying in the stimulus it provided to convergence. Both the preadaptation and postadaptation estimates showed that the reciprocal of estimated target distance is linearly related to convergence. Further there was a consistent change in the direction of adaptation expected from the preadaptation to the postadaptation test. This change was accounted for in terms of a recalibration of the effective absolute convergence level.     

From Validating to Verifying: Public Appeals in Synthetic Biology

Synthetic biology provides a vivid and richly entangled contemporary example of a science being made public. A science, however, can be made public in different ways. A public could validate, legitimate, de-legimate, object to, verify, confirm or dissent from science. Practically, scientists could publicise science—in the mass media—or they could make science public. The contrast between high-profile, media scientists such as J. Craig Venter, and community-based participatory mechanisms such as OpenWetWare allows us to see how these alternatives play out in practice. While it is easy to criticise and dismiss the public-relations oriented promotion of synthetic biology by figures such as Venter, how should we evaluate the open participatory mechanisms of a social media effort such as OpenWetWare? I suggest, drawing on the work of Isabelle Stengers and Michael Warner, that the case of synthetic biology is interesting because many synthetic biologists commit themselves to making it public, and making its public-ness part of how it is done. They place hope in publics to make the science viable. At the same time, however, the publics who are welcomed into OpenWetWare are largely confined to validating the coordination mechanisms on which the claim to public-ness rests. Whether publics can do more than validate synthetic biology, then, remains a question both for publics outside and inside this emerging scientific field. And whether the alternatives of validation or participation themselves adequately frame what is at stake in the emergence of fields such as synthetic biology remains debatable.     

Einschränkungen der Willensfreiheit bei somatoformen Störungen

Etiopathogenetic models of somatoform disorders and philosophical concepts of free will refer to theories of affect processing: affective dysregulation can promote psychosomatic ailments as well as problems in decision making. This observation brings forth the question if freedom of will is impaired in persons with somatoform disorders. By compiling, analyzing and contextualizing relevant models of current neuroscience, psychosomatic medicine and philosophy the psychodynamic construct of alexithymia as an etiologic factor of somatoform disorders and the conceptual integration of affective factors in a model of free will are developed on the basis of a common concept of affect. The synthesis of the discussed results and considerations, the multidimensional impairment of the ability to decide freely and self-determinedly due to somatoform disorders, is critically reflected; however, a blanket assumption is not admissible.     

The relationship between dietary restraint and deficits in reasoning about causes of obesity

Abstract

Objective: Increased levels of dietary restraint are associated with deficits on many cognitive tasks. Less is known about how individual differences in restraint influences complex cognition such as reasoning which is the focus of this research.

Design: Two experimental studies are reported. In study 1, participants (n?=?158) completed a causal conditional reasoning task with statements about weight-related and general causal relationships. Study 2 replicated and extended study 1. Participants (n?=?108) completed a causal conditional reasoning task focusing on behavioural causes of weight change or general statements.

Main outcome measure: Causal conditional reasoning task performance.

Results: In study 1, levels of dietary restraint were negatively associated with reasoning abilities for weight-related statements only. Study 2 replicated the negative association between dietary restraint and reasoning finding the effect in both weight-related, and general, causal judgements.

Conclusion: The novel findings show that individual differences in dietary restraint have a wider relationship with cognition than previously demonstrated. Results tentatively support theoretical explanations of a reduction in cognitive capacity, rather than differences in belief, explaining reasoning deficits. These findings open an interesting avenue for research and might have implications for effective decision making about personal health behaviours, such as food choice.     

How to Model Heterogeneity in Costly Punishment: Insights from Responders' Response Times

We investigate what processes may underlie heterogeneity in social preferences. We address this question by examining participants' decisions and associated response times across 12 mini‐ultimatum games. Using a finite mixture model and cross‐validating its classification with a response time analysis, we identified four groups of responders: one group takes little to no account of the proposed split or the foregone allocation and swiftly accepts any positive offer; two groups process primarily the objective properties of the allocations (fairness and kindness) and need more time the more properties need to be examined; and a fourth group, which takes more time than the others, appears to take into account what they would have proposed had they been put in the role of the proposer. We discuss implications of this joint decision–response time analysis. Copyright © 2013 John Wiley & Sons, Ltd.     

Assessing Aberrant Personality in Managerial Coaching: Measurement Issues and Prevalence Rates across Employment Sectors

The convergent and discriminant validity of two methods to assess a broad spectrum of aberrant personality tendencies was examined in a large sample of managers who were administered the NEO‐PI‐R (N = 11 862) and the Hogan Development Survey (N = 6774) in the context of a professional development assessment. Five‐Factor Model (FFM) aberrant compounds, defined as linear combinations of NEO‐PI‐R facets, converged for the antisocial, borderline, histrionic, avoidant and obsessive–compulsive tendencies with their respective Hogan Development Survey counterparts. Alternative linear FFM combinations did improve convergent results for the schizoid and obsessive–compulsive pattern. Risk for various aberrant tendencies was roughly equal across different employment sectors, with a higher prevalence of borderline, avoidant and dependent tendencies in the legal and more histrionic tendencies in the retail sector. Adopting FFM aberrant compound cut‐offs developed for coaching purposes to flag at risk individuals showed that 20% to 25% of all managers qualified for at least one and 10% to 15% were flagged as at risk for two or more aberrant tendencies. The theoretical implications and the repercussions of this research for the design of professional development and coaching trajectories are discussed.
