Testosterone,aggressiveness, and antisocial personality

Testosterone levels were examined in prisoners convicted of violent crimes (n = 13), in men previously convicted of violent crimes but currently not in prison (n = 15), in nonviolent alcoholics (n = 15), and in randomly selected control males (n = 16). Morning, afternoon, and evening testosterone levels were assessed after a minimum alcohol abstinence period of 24 hr. Violent and nonviolent men did not differ in plasma total testosterone level on any sampling occasion. In violent men, however, testosterone levels were significantly correlated with hostility, as measured by the Derogatis Symptom Check List. Most violent men were diagnosed with Antisocial Personality Disorder (ASP) [DSM‐III‐R; 301.70], and the unweighted ASP symptom count also correlated significantly with testosterone levels in these subjects. We suggest that individuals whose life histories involve numerous antisocial behaviors tend to have high testosterone levels even when interpersonal violence is excluded. This, however, does not eliminate the possibility that males who are characterized by high hostility may also have elevated testosterone levels. Violent predisposition and antisocial conduct beginning in early adolescence predict adult aggressive behaviors, which are augmented by power‐related alcohol expectancies and alcohol abuse. Aggr.

More Spousal Support for Men Than for Women: A Comparison of Sources and Types of Support

Types and sources of received support among 902 Costa Rican employees were examined; gender and age differences as well as associations with mental health were considered. Four types of support (advice giving, assistance, reassurance, and empathic listening) were measured as received from four sources, namely friends, family, spouses, and groups/organizations. Support types were not very distinct, therefore we aggregated sum scores across these variables. In contrast, sources were discriminant and had to be analyzed separately. An interaction between gender and age pointed to a larger discrepancy of received spousal support in middle-aged men and women than in younger ones. The older the women were, the less support they received from their spouses. In addition to this interaction, further gender differences emerged at the correlation level, where the association between spousal support and depression was significant for men only.     

Microsaccadic modulation of response times in spatial attention tasks

Covert shifts of attention are usually reflected in RT differences between responses to valid and invalid cues in the Posner spatial attention task. Such inferences about covert shifts of attention do not control for microsaccades in the cue-target interval. We analyzed the effects of microsaccade orientation on RTs in four conditions, crossing peripheral visual and auditory cues with peripheral visual and auditory discrimination targets. Reaction time was generally faster on trials without microsaccades in the cue-target interval. If microsaccades occurred, the target-location congruency of the last microsaccade in the cue-target interval interacted in a complex way with cue validity. For valid visual cues, irrespective of whether the discrimination target was visual or auditory, target-congruent microsaccades delayed RT. For invalid cues, target-incongruent microsaccades facilitated RTs for visual target discrimination but delayed RT for auditory target discrimination. No reliable effects on RT were associated with auditory cues or with the first microsaccade in the cue-target interval. We discuss theoretical implications on the relation about spatial attention and oculomotor processes.     

Aesthetics of streetscapes: influence of fundamental properties on aesthetic judgments of urban space

This experiment was designed to investigate the relationship between the fundamental visual, spatial properties of existing complex streetscapes and aesthetic judgments. Participants performed aesthetic judgments over 35 photographs of typical spatial situations taken along the Meissner Strasse in Radebeul, Germany. In a modified Q-Sort procedure, the participants assigned the pictures to five categories, including 1 (beautiful) and 5 (not beautiful). Vegetation, Stylistic Uniformity, Homogeneity of Scale, and Symmetry were identified as primary components of aesthetic judgment by using principal component analysis. Stimuli, photographically edited according to these factors, were then tested using the same Q-Sort procedure, which confirmed these determinants. These results are intended to help the development of the theoretical understanding of the link between the influence of selected spatial properties and the aesthetic judgment of the visual quality of urban spaces.     

Age differences between children and young adults in the dynamics of dual-task prioritization: body (balance) versus mind (memory)

Task prioritization can lead to trade-off patterns in dual-task situations. The authors compared dual-task performances in 9- and 11-year-old children and young adults performing a cognitive task and a motor task concurrently. The motor task required balancing on an ankle-disc board. Two cognitive tasks measured working memory and episodic memory at difficulty levels individually adjusted during the course of extensive training. Adults showed performance decrements in both task domains under dual-task conditions. In contrast, children showed decrements only in the cognitive tasks but actually swayed less under dual-task than under single-task conditions and continued to reduce their body sway even when instructed to focus on the cognitive task. The authors argue that children perform closer to their stability boundaries in the balance task and therefore prioritize protection of their balance under dual-task conditions.     

Whistle-Blowing from the Perspective of General Strain Theory

Authorities in many countries rely on whistle-blowing systems to boost control of organizational deviance. It can hardly be answered whether this practice is legitimate and efficient without knowing the patterns of whistle-blower behavior. So far, little is known about the development process as an interaction of specific individual, organizational, and situational conditions that spawns especially external reports. This article reconstructs such typical progressions based on interviews with whistle-blowers in Germany and from the perspective of the General Strain Theory. It turns out that external whistle-blowing is often the result of an escalating conflict that can be interpreted as a very personal experience of strain.
