In the current study, we addressed several issues related to the forms (physical and relational) and functions (reactive and proactive) of aggression in community (n = 307), voluntary residential (n = 1,917), and involuntarily detained (n = 659) adolescents (ages 11-19 years). Across samples, boys self-reported more physical aggression and girls reported more relational aggression, with the exc...

Behavioral scientists such as Freudian-Florence believe that aggression is a behavior rooted in human nature. These two believe that aggression as a latent force in humans has a hydraulic state that gradually becomes compacted and compressed in the individual, and eventually needs to be discharged. Aggression is a common phenomenon that athletes often deal with directly or indirectly. Rarely ca...

We have previously tested the hypothesis that differential DNA methylation signatures in peripheral T cells are associated with a chronic aggression trajectory in males. Despite the fact that sex differences appear...

This study used data from 6 sites and 3 countries to examine the developmental course of physical aggression in childhood and to analyze its linkage to violent and nonviolent offending outcomes in adolescence. The results indicate that among boys there is continuity in problem behavior from childhood to adolescence and that such continuity is especially acute when early problem behavior takes t...

Adult humans are characterized by low rates of intra-group physical aggression. Since children tend to be more physically aggressive, an evolutionary developmental account shows promise for explaining how physical aggression is suppressed in adults. I argue that this is achieved partly through extended dominance hierarchies, based on indirect reciprocity and linguistic transmission of reputatio...

Aggressive individuals are at increased risk of poor health, early mortality, mental health problems, and decreased life satisfaction. However, recent research suggests that trait aggression is not a unitary phenomenon. To date, most personality research on the topic has focused on direct aggression. Individuals high in trait direct aggression tend to respond to provocation with immediate anger...
