Perception of line‐up suggestiveness: effects of identification outcome knowledge

Research on the hindsight bias has shown that knowledge of an event outcome makes the observed outcome appear more predictable than it does in the absence of outcome knowledge. It was hypothesised that perceptions of the suggestiveness of a line‐up would be similarly influenced by knowledge of a witness' identification decision, with a positive identification of the suspect increasing, and a negative non‐identification decreasing, perceived suggestiveness. The ratings of undergraduate students (N = 50) in Experiment 1 showed the predicted influence of positive outcome, whereas negative outcome had no demonstrable influence. In contrast, Experiment 2, conducted with police trainees (N = 126) and with the line‐up presented in the context of a criminal investigation, partially supported the predicted influence of negative, but not positive, outcome. The discrepant findings are discussed in terms of the cognitive mechanisms underlying the hindsight bias and the implications for real‐life judgements of line‐up suggestiveness.

Patientensuizid im psychiatrischen Fachkrankenhaus

Suicide prevention especially with psychiatric inpatients is traditionally a very important aspect of psychiatric treatment. During the 1970s and 1980s there was a noticeable increase in so-called hospital suicides in Germany, especially suicides of schizophrenic inpatients. The number of psychiatric inpatient suicides has currently decreased again and a shift to more depressive suicides has also been observed. Furthermore questions which are asked in court are presented and discussed.     

On the Proof-theoretic Foundation of General Definition Theory

A general definition theory should serve as a foundation for the mathematical study of definitional structures. The central notion of such a theory is a precise explication of the intuitively given notion of a definitional structure. The purpose of this paper is to discuss the proof theory of partial inductive definitions as a foundation for this kind of a more general definition theory. Among the examples discussed is a suggestion for a more abstract definition of lambda-terms (derivations in natural deduction) that could provide a basis for a more systematic definitional approach to general proof theory.     

Power and Participation: Social Representations among Children in Pre-school

Children’s play is usually connected with qualities such as happiness and innocence, and regarded as important and necessary for learning and development. However, play is not always a state of joy. Experiences of being socially excluded or ignored and of taking part in such activities are occurring. The article draws on a re-analysis of empirical data from a study of pre-school children’s play. The focus in the article is directed towards how pre-school children within the context of play communicate and act in relation to social participation and power. The theoretical framework is built upon a socio-cultural research tradition, particularly emphasising context and communication. Interpretive reproduction, secondary adjustment, and social representations are used as additional theoretical concepts in the analyses and discussions of the results. Empirical data show that children’s social representations of power and participation in play include rationales for who can join the play and who can not, and also how to allow exceptions from the main rule that ‘anyone can join’.     

Short-term plasticity of the visuomotor map during grasping movements in humans

During visually guided grasping movements, visual information is transformed into motor commands. This transformation is known as the "visuomotor map." To investigate limitations in the short-term plasticity of the visuomotor map in normal humans, we studied the maximum grip aperture (MGA) during the reaching phase while subjects grasped objects of various sizes. The objects seen and the objects grasped were physically never the same. When a discrepancy had been introduced between the size of the visual and the grasped objects, and the subjects were fully adapted to it, they all readily interpolated and extrapolated the MGA to objects not included in training trials. In contrast, when the subjects were exposed to discrepancies that required a slope change in the visuomotor map, they were unable to adapt adequately. They instead retained a subject-specific slope of the relationship between the visual size and MGA. We conclude from these results that during reaching for grasping, normal subjects are unable to abandon a straight linear function determining the relationship between visual object size and MGA. Moreover, the plasticity of the visuomotor map is, at least in short term, constrained to allow only offset changes, that is, only "rigid shifts" are possible between the visual and motor coordinate systems.     

Collective fit increases team performances: extending regulatory fit from individuals to dyadic teams

People experience “regulatory fit” when they pursue a goal in a manner that suits their chronic regulatory orientation. This regulatory fit impacts performance positively. The present research extends performance gains due to fit from individuals to dyadic team performance. Study 1 manipulated team fit of 32 table football participants (i.e., promotion vs. prevention orientation and offense vs. defense positions). Team fit significantly predicted team success in an experimental tournament beyond team skill level. Study 2 replicated this result with data from a real‐life tournament including 66 highly experienced competitors. These findings broaden the concept of regulatory fit from individual to dyadic teams, and suggest collective fit as a possible important predictor for team success.     

Reduce Ourselves to Zero?: Sabina Lovibond,Iris Murdoch,and Feminism

In her book Iris Murdoch, Gender and Philosophy, Sabina Lovibond argues that Iris Murdoch's philosophical and literary work is covertly dedicated to an ideology of female subordination. The most central and interesting aspect of her multifaceted argument concerns Murdoch's focus on the individual person's moral self‐scrutiny and transformation of consciousness. Lovibond suggests that this focus is antithetical to the kind of communal and structural criticism of society that has been essential for the advance of feminism. She further reads Murdoch's dismissal of “structuralism” as proof of Murdoch's alleged conservatism and neglect of feminist concerns. In this article I will argue that this line of argument—though not completely off‐base concerning the awkwardness of Murdoch's relation to feminism—(1) gives a misleading picture of Murdoch's philosophical and ideological position, and (2) establishes a problematic (though not unusual) antagonism between moral self‐scrutiny and social criticism, which a closer look at Murdoch's work can help us overcome.     

Changes in Attachment‐Related Behavioural Problems of Internationally Adopted Toddlers in Finland: Results from the FinAdo Study

This study investigated attachment‐related behavioural problems and their change over time among internationally adopted toddlers (N = 171, boys 40%) in Finland. The parents filled in questionnaires posted in 2007 and again in 2009. At the baseline (on average, 1.9 years from adoption), the mean age of the adoptees was 2.8 years. The comparison group (N = 244, boys 46%) was collected through well‐baby clinics. Results from the paired t‐test and mixed models showed that the adoptees' attachment‐related behavioural problems decreased during the 2‐year follow‐up and that they did not manifest more problems than their age‐mates any more 4 years after adoption. The decrease in behavioural problems was associated with the child's female gender, country of origin and adoptive parents' positive experience about adoption. A child's stereotypic or self‐injurious behaviour was not associated with the change in attachment‐related behaviour over time, although both were associated with behavioural problems.
