Background: There is limited research into the nature and aetiology of temper outbursts in people with intellectual disabilities. In this study, we describe the phenomenology and environmental context of temper outbursts in Lowe syndrome, a rare genetic syndrome in which outbursts are purportedly frequent. Method: A temper outburst interview (TOI)…

Introduction: Children and young adults with Down syndrome can demonstrate increased behavior problems compared to their typically developing peers through childhood and adolescence. Though current tools measure behavior problems in persons with intellectual disabilities, they do not capture all the behavioral problems that can occur in…

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…

Aggressive behaviors in children and adolescents have undergone important conceptual and definitional modifications in the past two decades. In particular, subtypes of aggression have been proposed that separate the form and the function of the aggressive behaviors (i.e., social vs. physical aggression; reactive vs. proactive aggression).…

Twin children were videotaped hitting an inflated clown figure. Three behaviors (number of hits, intensity of hits, and number of quadrants hit) showed adequate response characteristics, rater reliability, and test-retest reliability. Twin analyses of the three behavioral ratings yielded no evidence of hereditary influence. (Author)

The principle thesis of this paper is that an understanding of the functions of fantasy activities is critical to an understanding of the influence of television and other media upon behavior. (Author)

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)

Presented children (N=96) aged 8-11 with verbal pain or nonpain stimuli contingent or noncontingent on a target response. Delivered stimuli within an aggressive or nonaggressive setting and with or without affect. Type of setting did not influence the behavior, but stimuli delivered in an affective manner did facilitate responding. (Author/RC)

A questionnaire was administered to 153 of 181 13-year-olds who had been assessed at ages 8-9. Results supported the hypothesis that for the majority, aggressive behavior is not a stable trait and cannot be accurately predicted as a recurrent pattern when using the opinions of teachers, peers, or the children themselves.

This study investigated aggressive, withdrawn, and prosocial behavior in 21 physically abused, 26 nonabused-neglected, and 21 nonabused-nonneglected children, ages 5-8. No single dimension adequately discriminated children in each of the three groups. Full discrimination was achieved only when aggressive, withdrawn, and prosocial behaviors were…

Offers evidence that exposure to television violence can increase childrens' tolerance of real-life aggression. (MH)

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…

Assessed the relationship between temporally distant antecedent events (TDEs) and the frequency and function of aggressive and out-of-seat behaviors occurring in school. Results were consistent with previous literature that describes certain antecedent events as establishing operations. Discussion includes how these events interact to alter the…
