Twin study of laboratory-induced aggression

The aim of this study was to explore genetic and environmental contributions to laboratory-induced aggressive behavior. On a sample of 478 adult twins (316 monozygotic), the Competitive Reaction Time Task was used for aggression induction. The results showed that the initial, basic level of aggression could be explained by both shared (45%) and nonshared environmental factors (55%), while only nonshared environmental factors (100%) had a significant influence on changes in aggression as provocation increased. Genetic factors had no influence on laboratory-induced aggression. The results highlight the importance of environmental factors in shaping situation-specific aggressive responses to provocation.     

Fromm’s understanding of the Buddhist philosophical theory and psychoanalysis: From the phenomenal ego to the authentic being1

Abstract

Erich Fromm was one of the first psychoanalytic thinkers who was genuinely interested in Asian philosophies. In the first part of this article, I will show Fromm’s imago of Buddhism as a radical, nontheistic, and ethical philosophy “without God.” I will argue that Fromm made an important difference between the phenomenal ego and being that proves crucial for his understanding of psychoanalysis and his critique of modern society. I will also explore Fromm’s synthesis of Buddhist philosophy and psychoanalysis, and show the similarities and differences between them.     

Idleness and Inmate Misconduct: A New Perspective on Time Use and Behavior in Local Jails

ABSTRACT

A growing body of literature explores how participation in programming in correctional institutions predicts inmate misconduct. Theory and extant research suggest that engagement in structured and prosocial activities promotes positive behavioral and emotional outcomes, while idleness has a negative impact on inmate behavior and well-being. However, the literature that examines these relationships is largely based on qualitative methodology, small samples, and prison population. Using data from the 2002 Survey of Inmates in Local Jails, this study fills the gap in the literature by examining the associations between engagement in various activities in jail and inmate misconduct. This study also explores individual and jail-level factors that predict inmate engagement in different activities in jails. The results show that watching TV and working in jail are associated with lower misconduct, whereas recreation and reading are associated with higher levels of several types of misconduct. The data also reveal that certain personal and institution-level factors predict the extent of engagement in formal and leisure activities.     

Cross-cultural differences in temperament: Comparing paternal ratings of US and Dutch infants

This study conducted longitudinal comparisons of US and Dutch paternal ratings of temperament, measured via the Infant Behaviour Questionnaire-Revised, at 4 months (US n = 99; Dutch n = 127) and 12 months (US n = 66; Dutch n = 112) of age. US fathers rated their infant higher in the broad temperament trait Surgency, and its subscales vocal reactivity, high-intensity pleasure, and activity level. US fathers also rated their infants higher in negative emotionality, and its subscales of sadness, distress to limitations, and fear. Dutch infants received higher ratings in falling reactivity. Though the cultures did not differ in ratings of Orienting/regulatory capacity, US infants were higher on the subscale duration of orienting, and lower in soothability. Significant culture-by-age and culture-by-gender interactions were also noted. Overall, results are largely consistent with those reported for Dutch mothers and speak to considerable differences in early temperament development between cultures viewed as largely similar because of their Western/individualistic orientations.
