PURPOSE Aggression continues to challenge caregivers of persons with dementia, and identification of foci for effective interventions is needed. The purpose of this study was to examine the influence of (a) the resident characteristics of depression, communication, and cognition and (b) behavior management strategies on aggression in a group of older nursing home residents (N = 405) with eviden...

Distinguishing between relational and physical aggression has become a key feature of many developmental studies in North America and Western Europe, but very little information is available on relational and physical aggression in more diverse cultural contexts. This study examined the factor structure of, associations between, and gender differences in relational and physical aggression in Ch...

Laboratory studies of alcohol-inexperienced adolescents show that aggression can be primed by alcohol-related stimuli, suggesting that alcohol-related aggression is partly socially learned. Script theory proposes that alcohol-related aggression 'scripts' for social behaviors are culturally-available and learned by individuals. The purpose of the study was to understand the content and origins o...

Boys and girls may display different styles of aggression. The aim of this study was to identify subtypes of aggression within the Child Behavior Checklist (CBCL) aggression scale, and determine their characteristics for both sexes. Maternal CBCL ratings of 7449 7-year-old twin pairs were analyzed using principal components analyses to identify subtypes of aggression, and structural equation mo...

Lactating female rodents protect their pups by expressing fierce aggression, termed maternal aggression, toward intruders. Mice lacking the neuronal nitric oxide synthase gene (nNOS-/-) exhibit significantly impaired maternal aggression, but increased male aggression, suggesting that nitric oxide (NO) produced by nNOS has opposite actions in maternal and male aggression. In contrast, mice lacki...

Captive groups of primates often exhibit higher rates of aggression than wild, free-ranging groups. It is important to determine which factors influence aggression in captivity because aggression, particularly intense aggression, can be harmful to animal health and well-being. In this study, we investigated the effect of ground substrate as well as season, rank, age, and group size on rates of ...

Predatory (towards crickets), intermale, and maternal aggression were examined in four replicate lines of mice that had been selectively bred for high wheel-running (S) and in four random-bred control lines (C). In generation 18, individual differences in both predatory and intermale aggression were significantly consistent across four trial days, but predatory and intermale aggression were unc...

While persuasive evidence has accumulated over the past 15 years documenting an association between schizophrenia and violence, there are 3 unresolved issues. First, does a downward extension of this relationship exist at the nonclinical level with respect to schizotypal personality and aggression in children? Second, is aggression more associated with impulsive reactive aggression or with more...

Crick, Murray-Close, and Woods (2005) encouraged the study of relational aggression as a developmental precursor to borderline personality features in children and adolescents. A longitudinal study is needed to more fully explore this association, to contrast potential associations with physical aggression, and to assess generalizability across various cultural contexts. In addition, parenting ...
