Background: Behaviour problems and a preference for adult contact are reported to be prominent in the phenotype of Smith-Magenis syndrome. In this study we examined the relationship between social interactions and self-injurious and aggressive/disruptive behaviour in Smith-Magenis syndrome to explore potential operant reinforcement of problem…

Common in the research literature on bullying is the dichotomy of bullying and victim behavior. The present definition of a bully is a person who has engaged in repeated acts of aggression or harm to persons over whom he or she has power. The literature on bullies examines gender differences at length. However, the bully-victim literature has yet…

This study of 12 residents of a treatment facility for individuals with mental retardation examined cycles in occurrences of self-injurious behavior (SIB) and aggression both within and across individuals. The study confirmed that such behavior tended to be rhythmical, with cycles of three-month and five-month periods consistently observed for…

Two studies examined the hypothesis that sexually coercive behavior is part of a larger constellation of non-sexual deviant behaviors. The first study considered the relationship between various antisocial intentions and self-reported levels of sexual aggression. As a part of a larger study, college men (N=108) responded to the Sexual Experiences…

Counteraggression is discussed as a biological function or survival instinct that escalates violence in schools. Expands Fritz Redl's explanation of underlying reasons why staff dealing with delinquent youth become counteraggressive. Preventing or controlling counteraggressive behavior through analysis of the reasons behind the reaction can help…

Studies the aggressiveness of over 600 subjects, their parents, and their children over a 22-year period. Subjects who were more aggressive 8-year-olds were more aggressive 30-year-olds, exhibiting serious antisocial behavior as adults. The stability of aggression across generations within a family was also high. (Author/CB)

The effects of 80 second- through fifth-grade boys and girls of three types of adult commentary (anti-aggressive, nonaggressive, neutral), presented during a violent TV show, were examined and compared to a nonviolent control film group. Subjects' latency in seeking responsible adult assistance when witnessing "real" aggression among…

Summarizes the major research findings on the relationship between television violence and aggressive behavior; concludes that, while there is no definitive proof that such a relationship exists, the evidence points strongly in that direction. (GT)

In a group of 20 severely to profoundly mentally retarded adults, an interactional dominance hierarchy was obtained by observing the frequency of patient contacts, the duration of contact, and the frequency of contact initiation. It was found that 17 of the 20 patients studied displayed territorial behavior. (Author)

This study examined three maladaptive behaviors, self-injurious behavior (SIB), stereotypies, and aggression in 36 adults with either autism, pervasive developmental disorder not otherwise specified (PDD-NOS), and mental retardation. Findings indicated that, for all three diagnostic categories, aggression was primarily maintained for attentional…

This paper summarizes brief functional assessments of 79 cases of people with developmental disabilities and self-injurious, aggressive, stereotypic, or other aberrant behavior. Outcomes were evaluated across three variables: (1) referring topography, (2) control over behavior, and (3) the identified maintaining conditions for aberrant behavior.…

This study presents data on the physical, developmental, and behavioral characteristics of a group of 203 nonambulatory persons with profound mental retardation. It found a high prevalence of physical and medical problems, as well as high rates of self-injurious, stereotypic, and aggressive behavior and high variability in cognitive and adaptive…

Reviewed are longitudinal studies of aggressive behavior and reaction patterns in three groups of males (preschool children, school-age children and adults), as observed or inferred by individuals other than the subjects themselves. (Author/MP)
