OBJECTIVE To determine whether involvement in sporting activity in mid-adolescence would deter delinquent behaviour in late adolescence. METHODS Members of a longitudinal cohort study were interviewed at ages 15 and 18 years and, among other topics, were asked questions relating to involvement in physical activity and delinquent behaviour. Logistic regression models were used to examine the r...

BACKGROUND Antisocial behaviour may partly develop as a consequence of psychopathic personality. However, neither the direction of effects nor the aetiology of the association has previously been clarified. The aim in this study was to investigate the direction of effects between psychopathic personality and antisocial behaviour, and to investigate the genetic and environmental contribution to ...

It has been proven extremely difficult in the past to estimate the prevalence of physical aggression in children for two main reasons: (a) a heterogeneous sampling of behaviors (i.e., mix between physically aggressive and non-physically aggressive antisocial behaviors), and (b) a lack of a "gold standard" to identify children who exhibit physically aggressive behaviors on a frequent basis. The ...

Psychopathy (PP) is associated with marked abnormalities in social emotional behaviour, such as high instrumental aggression (IA). A crucial but largely ignored question is whether automatic social approach-avoidance tendencies may underlie this condition. We tested whether offenders with PP show lack of automatic avoidance tendencies, usually activated when (healthy) individuals are confronted...

Testosterone promotes aggressive behaviour in male vertebrates during the breeding season, but the importance of testosterone in female aggression remains unclear. Testosterone has both beneficial and detrimental effects on behaviour and physiology, prompting the hypothesis that selection favours an association between aggression and testosterone only in certain contexts in which intense or per...

The present work analyses differences in the attachment representations of institutionalized children as compared with children from low and high educational level living with their natural families. Participants were 91 Portuguese children, 52% girls, aged 48-96 months. There were three different groups: 19 institutionalized children, 16 low educational level families' children and 56 from hig...

The reproductive behaviour of the sexually coercive male eastern mosquitofish (Gambusia holbrooki) offers an excellent model system for testing the benefits of reversible thermal acclimation responses to mating success. We acclimated male mosquitofish to either 18 or 30 degrees C (14 h light:10 h dark) for six weeks and tested their ability to obtain coercive copulations in the presence and the...

The aim of investigation was to assess the impact of subjective stress exposure on delinquent behaviour in children and adolescents. The study included 174 young male delinquents, selected by the method of stratified systematic (random) sample and divided into three age groups of <14, 14-17, and 18-21 years. General data, data on the type of criminal offence, and data on the type of deviant beh...

AIM The authors define the term "satisfaction from life" as being able to achieve satisfying objectives, realize one's own needs and desires. Such a vision depends upon personal experience, knowledge, role models and value system. The objective of this study is to establish the styles of coping with stress, as well as kinds and intensity of aggressive behaviours that depend on the degree of lif...

Themes of dominance and territoriality have long been part of automobile driving, which has aLso involved flagrant assaultive actions. Recent episodes of roadway violence in metropolitan areas have raised community concem about aggressive behavior in driving, although common beliefs about why such violence occurs can ...
