All animals interact with conspecifics during their life, and nearly all also display some form of aggression. An enduring challenge, however, is to understand how the experiences of an individual animal influence its later behaviours. Several studies have shown that prior winning experience increases the probability of initiating fights in later encounters. Using behavioural assays in the labo...

The relative contributions to sexual aggression of general sexual and aggressive motives and their respective inhibitory factors were compared. One hundred forty-three university males responded to self-report measures of sexual and aggressive drives, sex and hostility guilt, social desirability response bias, and history of coercive sexuality. With the effects of social desirability controlled...

Non Hodgkin Lymphomas (NHL) are nodal or extra nodal monoclonal infiltrations by malignant lymphoid cells (B Lymphocytes in 80% of cases), which are distinguished as indolent or aggressive forms. According to the heterogeneity of lymphoid cells and their ubiquitous anatomical distribution, these disorders can develop in any organ and have very heterogeneous clinical expressions, but they are...

Lizards provide a rich opportunity for investigating the mechanisms associated with arousal and the display of motivated behaviors. They exhibit diverse mating strategies and modes of conspecific communication. This review focuses on anole lizards, of which green anoles (Anolis carolinensis) have been most extensively studied. Research from other species is discussed in that context. By conside...

This study examined adolescent narcissism, temperament (frustration and affiliation), and social goals in association with peer-reported physical and relational aggression (N = 384; 12-14 years). Narcissism was positively associated with dominance goals and negatively with closeness goals for peer interaction. Moreover, narcissism was positively associated with physical aggression via dominance...

To explore the way in which the interpretation of ambiguous social behavior can be influenced by racial stereotypes and cultural differences, 40 black and 40 white 6th-grade males were shown a variety of ambiguously aggressive behaviors performed by black and white stimulus figures. As predicted, both black and white preadolescents rated these behaviors as more mean and threatening when the per...

This study examined the implementation of a model of managing aggressive and harmful behaviour in an adolescent in-patient psychiatric unit. This model, Positive Behaviour Management, replaced a previous model, Control and Restraint, which was considered unsuitable. Both models included the use of physical interventions, and the research into such techniques is considered. The aims of the study...
