The Trophy Effect

By extending a typical endowment effect experiment with the possibility of winning the endowment in a real effort contest, we found two reinforcing effects that led to a complete market failure. Subjects who won the item in the effortful competition had a very high willingness to accept (trophy winner effect). By contrast, subjects who were not successful had an extremely low willingness to pay for the same item (trophy loser effect). We disentangle different components of these effects and investigate the underlying emotional responses. Further, we analyze the duration of the effects and discuss economic implications.

Visual snake aversion in Octodon degus and C57BL/6 mice

Animal Cognition - Phobia against spiders or snakes is common in humans, and similar phobia-like behaviors have been observed in non-human animals. Visual images of snakes elicit phobia in humans,...     

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.     

The Body Grid as an Assessment Tool for Body Image

The aim of this study was to analyze the body grid (BG) as an assessment tool for body image in a sample of patients with breast cancer, after surgery. We explored two measures of cognitive structure, percentage of variance accounted for by the first factor (PVAFF) and polarization, and we compared measures of body image and body self-esteem obtained by means of the BG with those obtained via a validated body image questionnaire. Our sample was composed of 23 patients (12 subjected to radical mastectomy, 11 subjected to conserving surgery) and 24 healthy controls. Participants were administered the BG and the Multidimensional Body Self Relations Questionnaire (MBSRQ). We analyzed the similarities between instruments using correlations and nonparametric tests. We have also provided two case studies to exemplify the use of the BG.

?We found statistical differences in cognitive structure between patients and healthy controls. There were no differences between women subjected to mastectomy and women with breast conserving surgery in the level of PVAFF, but there were significant differences between them in the level of polarization. We found significant correlations between body image indices of both instruments, especially self-evaluated attractiveness (MBSRQ) and distance between real and ideal body (BG). We found similar distributions of these indices in all of the samples. We concluded that the BG provides useful information about body image. The results show that both instruments assess similar constructs. This suggests that the BG is a valid instrument for body image assessment.     

Socialization of prosocial behavior: Gender differences in the mediating role of child brain volume

Evidence has been accumulating for the impact of normal variation in caregiving quality on brain morphology in children, but the question remains whether differences in brain volume related to early caregiving translate to behavioral implications. In this longitudinal population-based study (N = 162), moderated mediation was tested for the relation between parental sensitivity and child prosocial behavior via brain volume, in boys and girls. Both maternal and paternal sensitivity were repeatedly observed between 1 and 4 years of age. Brain volume was assessed using magnetic resonance imaging measurements at age 8, and self-reported prosocial behavior of children was assessed at 9 years of age. Parental sensitivity was positively related to child brain volume, and to child prosocial behavior at trend level. Child brain volume was negatively related to child prosocial behavior. A significant gender-by-brain interaction was found, illustrating that daughters of sensitive parents were more prosocial and that less prosocial behavior was reported for girls with a larger total brain volume. Child gender significantly moderated the indirect effect of parental sensitivity on prosocial behavior via total brain volume. A significant indirect pathway was found only in girls. The results warrant replication but indicate the importance of considering gender when studying the behavioral implications of differences in brain volume related to early caregiving experiences.     

Mangelnde Eignung bei angehenden Psychotherapeuten

Background

Psychotherapy research has shown that some therapists have systematically more negative outcomes than their colleagues. Many attempts have been made to answer the question of whether these unsuccessful therapists have specific features but as yet no consensus has been reached. Particularly in the field of psychotherapy training this issue has rarely been discussed.

Aims

This study focused on the following questions: how many trainees are incompetent, what characteristics do they have and how to deal with them? How are trainees selected?

Material and methods

In a research expertise on psychotherapy training for the German Ministry of Health, directors of training institutions were interviewed and 129 responses were analyzed using, for example content analysis.

Results

A total of 4–5?% of trainees were judged as being not sufficiently competent to become a psychotherapist. Relevant criteria were mainly the lack of personal and interpersonal competencies.

Conclusions

Future psychotherapy training should focus more and earlier on recognizing and intervening regarding incompetence in the given areas.
