The relationship between testosterone and aggression: a meta-analysis

In non-human animals, the relationship between testosterone and aggression is well established. In humans, the relationship is more controversial. To clarify the relationship, Archer conducted three meta-analyses and found a weak, positive relationship between testosterone and aggression. Unfortunately, each of the analyses included only five to six studies. The aim of the present study was to re-examine the relationship between testosterone and aggression with a larger sample of studies. The present analyses are based on 45 independent studies (N=9760) with 54 independent effect sizes. Only studies that reported a p-value or effect size were included in the analyses and the sample may underestimate the proportion of non-significant findings in the population. Correlations ranged from −0.28 to 0.71. The mean weighted correlation (r=0.14) corroborates Archer's finding of a weak positive relationship.     

Context and Message Content During Organizational Socialization

This study examined the socialization experiences of 85 newly hired managers over a 4‐month period. Results indicated partial support for a model proposing a mediating relationship among structured and unstructured socialization contexts, socialization message content, and newcomer adjustment. Performance proficiency message content mediated the impact of fixed and serial tactics on role ambiguity while sequential tactics and trial by fire experiences had a direct effect. Investiture tactics were negatively related to new manager role innovation.
