In "Drosophila," prior fighting experience influences the outcome of later contests: losing a fight increases the probability of losing second contests, thereby revealing "loser" effects that involve learning and memory. In these experiments, to generate and quantify the behavioral changes observed as consequences of losing…

In order to recognize behavioral patterns in children and adolescents at risk for developing bipolar disorder, this study examined Child Behavior Checklist (CBCL) profiles of bipolar offspring both with (BD group) and without ("at-risk" or AR group) bipolar disorder themselves.

One hundred three adolescents (X age = 12 years, 11 months; SD = 12.46 months) are individually…

Literature assessing knowledge of and attitudes toward social issues has demonstrated that mental health professionals and lay persons often differ greatly. To add to the normative information in the field of psychological abuse and to determine whether the differences previously found between mental health professionals and lay persons extend to…

Research has revealed a considerable degree of stability of Type A behavior from adolescence to adulthood. Other research has reported an association between anger and certain dimensions of cardiovascular risk in adolescent subjects. Such findings suggest that further study of the Type A phenomenon as it is expressed in adolescents may enhance…

The Type A construct, which consists of such psychological components as a sense of time urgency, competitive aggressiveness, and easily aroused hostility wich are manifested under appropriately challenging circumstances, has been studied to a great extent in adult white males. There is less research, however, on how these characteristics are…

Certain characteristics of a Taylor (1965) competitive reaction time task contribute to a lack of awareness of contingencies that exist between two aggressors. The opponent's contingent response to the subject's specific shock setting may be obscured by the reaction time competition, thus concealing the matching contingency. Nine separate steps…

The current study examined the best friendships of aggressive and nonaggressive boys (N=96 boys, 48 dyads, mean age=10.6 years). Friends completed self-report measures of friendship quality, and their interactions were observed in situations that required conflict management and provided opportunities for rule-breaking behavior. Although there…

While a great deal of clinical research attention has been directed toward assertive training, there have been few studies examining the social impact or interpersonal evaluation of assertive versus unassertive behavior, including the differential evaluation of assertiveness exhibited by males and females. In this study, subjects observed a…

Compared child outpatients with diagnoses for both conduct disorder (CD) and attention deficit disorder with hyperactivity (ADD/H) with children with CD but no ADD/H. Children with both CD and ADD/H exhibited more physical aggression and a greater variety and severity of antisocial behaviors despite their younger age at time of referral than did…

Suggests that intrapersonal and interpersonal conflicts are influential in marital relationships.

Happy couples also had more loyalty to their communities, more energy for tasks, and more positive…

Subjects either punished incorrect or rewarded correct responses made by a confederate on a learning task. In three experiments subjects were, interrupted midway through the learning trials. Half were individuated and half were deindividuated; they were provided a "hot-line" to summon the experimenter. Found no reliable methods for inhibiting…

In an extension of an earlier study by Cline, Croft, and Courrier (1973) the effects of amount of television viewing and preference for televised violence upon autonomic responses to violent and nonviolent videotaped movie sequences were examined. Thirty-six male undergraduates watched a six-minute portion of a boxing film and a six-minute portion…

In the first of two studies, male undergraduates were either angered or not angered by a confederate. In the second study, subjects in the angry condition displayed more aggression, and thwarting increased subsequent aggressivity. (Author)

While evidence is mixed about whether aggressive children generate fewer alternative solutions to social problems than do nonaggressive children, research has found consistent deficiencies in the qualitative kinds of solutions that aggressive children produce. This study assessed salience effects on the abilities of aggressive and nonaggressive…
