Tatbilder schizophrener und wahnhafter Täter

Besides the ongoing discussion on whether persons with schizophrenia have a higher prevalence of criminal offences, it is also of special interest for the prognosis in this group of offenders whether there is a causal relationship between the schizophrenic disease and the type of delinquency. For the construction of causal relationships it is important to determine a typology of offences committed by schizophrenic persons. This article deals with the problem by analyzing the offences of 133 patients diagnosed with schizophrenia, schizo-affective and delusional disorders at the Landschaftsverband Westfalen-Lippe (LWL) Center for Forensic Psychiatry in Lippstadt.     

Auditory color constancy: Calibration to reliable spectral properties across nonspeech context and targets

Brief experience with reliable spectral characteristics of a listening context can markedly alter perception of subsequent speech sounds, and parallels have been drawn between auditory compensation for listening context and visual color constancy. In order to better evaluate such an analogy, the generality of acoustic context effects for sounds with spectral-temporal compositions distinct from speech was investigated. Listeners identified nonspeech sounds—extensively edited samples produced by a French horn and a tenor saxophone—following either resynthesized speech or a short passage of music. Preceding contexts were “colored” by spectral envelope difference filters, which were created to emphasize differences between French horn and saxophone spectra. Listeners were more likely to report hearing a saxophone when the stimulus followed a context filtered to emphasize spectral characteristics of the French horn, and vice versa. Despite clear changes in apparent acoustic source, the auditory system calibrated to relatively predictable spectral characteristics of filtered context, differentially affecting perception of subsequent target nonspeech sounds. This calibration to listening context and relative indifference to acoustic sources operates much like visual color constancy, for which reliable properties of the spectrum of illumination are factored out of perception of color.     

Supervisory mentoring and employee affective commitment and turnover: The critical role of contextual factors

Past research has largely ignored the role of contextual factors in the relationships between supervisory mentoring and individual and organizational outcomes. In order to fill this void, we investigate how job scope and career and development opportunities, two critical contextual factors, moderate the supervisory mentoring-affective commitment-turnover links. Integrating social exchange theory with insights from situational approaches to leadership, we hypothesized that (a) job scope would interact with supervisory mentoring in predicting affective commitment and (b) career and development opportunities would interact with affective commitment in predicting turnover such that the conditional effects of supervisory mentoring on turnover would be stronger at high levels of these contextual moderators. Results of a study conducted with a sample of 228 business alumni, using 15-month voluntary turnover as outcome, supported our predictions. We discuss the implications of these findings for mentoring research and practice.     

Unravelling the Interplay Between Genetic and Environmental Contributions in the Unfolding of Personality Differences from Early Adolescence to Young Adulthood

In two studies, we examined the genetic and environmental sources of the unfolding of personality trait differences from childhood to emerging adulthood. Using self‐reports from over 3000 representative German twin pairs of three birth cohorts, we could replicate previous findings on the primary role of genetic sources accounting for the unfolding of inter‐individual differences in personality traits and stabilizing trait differences during adolescence. More specifically, the genetic variance increased between early (ages 10–12 years) and late (ages 16–18 years) adolescence and stabilized between late adolescence and young adulthood (ages 21–25 years). This trend could be confirmed in a second three‐wave longitudinal study of adolescents' personality self‐reports and parent ratings from about 1400 Norwegian twin families (average ages between 15 and 20 years). Moreover, the longitudinal study provided evidence for increasing genetic differences being primarily due to accumulation of novel genetic influences instead of an amplification of initial genetic variation. This is in line with cumulative interaction effects between twins' correlated genetic makeups and environmental circumstances shared by adolescent twins reared together. In other words, nature × nurture interactions rather than transactions can account for increases in genetic variance and thus personality variance during adolescence. © 2019 European Association of Personality Psychology     

The time course of working memory effects on visual attention

Previous work has generated inconsistent results with regard to what extent working memory (WM) content guides visual attention. Some studies found effects of easy to verbalize stimuli, whereas others only found an influence of visual memory content. To resolve this, we compared the time courses of memory-based attentional guidance for different memory types. Participants first memorized a colour, which was either easy or difficult to verbalize. They then looked for an unrelated target in a visual search display and finally completed a memory test. One of the distractors in the search display could have the memorized colour. We varied the time between the to-be-remembered colour and the search display, as well as the ease with which the colours could be verbalized. We found that the influence of easy to verbalize WM content on visual search decreased with increasing time, whereas the influence of visual WM content was sustained. However, visual working memory effects on attention also decreased when the duration of visual encoding was limited by an additional task or when the memory item was presented only briefly. We propose that for working memory effects on visual attention to be sustained, a sufficiently strong visual representation is necessary.     

AIDS-Related Stigmatization: Instrumental and Symbolic Attitudes1

We investigate the role that instrumental and symbolic functions of attitudes play in the rejection of people infected with HIV. In a series of studies (total N = 431), we manipulate the symbolic component of AIDS, by comparing it to a fictitious disease that is identical in every way to AIDS, excepting its symbolic association with homosexuality and IV drug use. Two studies indicated that the symbolic component had no effect on either social distance or perceptions of disease severity. A third study indicated that instrumental aspects of severity, contagiousness, and treatability were significant determinants of social distance. A fourth study found that the stigma of association with homosexuality increased a mild disease's stigma. A fifth study showed that previous research showing the importance of a symbolic component in AIDS-related attitudes may have relied on a confounded measure of the symbolic component of attitudes. These 5 studies suggest the importance of both instrumental and symbolic attitudes in illness. Instrumental functions seem to outweigh the impact of symbolic functions of AIDS-related attitudes.     

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.     

Best Practice Recommendations Still Fail to Result in Action: A National 10‐Year Follow‐up Study of Investigative Interviews in CSA Cases

The present study examined a national sample of Norwegian investigative interviews in alleged child sexual abuse cases (N = 224) across a 10‐year period (2002–2012), in order to decide whether practice had improved over the decade in terms of the types of questions asked. The results indicate that the frequency of open‐ended, directive, option‐posing, and suggestive questions asked was unchanged during the 10‐year period, but that the frequency of repeated questions had increased significantly. When analyzed together with the results from a previous study of interview practice covering the period of 1990–2002, long‐term trends were found to be similarly stable, with no change in the frequency of open‐ended and suggestive questions asked over a 22‐year perspective. However, a decreasing frequency of option‐posing questions observed accompanied by an increasing frequency of directive questions may be considered a positive trend.
