The response patterns of youth who witness bullying have potential to influence future occurrence and persistence of bullying behaviors. Prevention efforts have included an increased focus on bystander interventions; however, the majority of adolescents rarely intervene in bullying situations. When they do, they often display of mixed pattern of…

Active avoidance (AA) is an important paradigm for studying mechanisms of aversive instrumental learning, pathological anxiety, and active coping. Unfortunately, AA neurocircuits are poorly understood, partly because behavior is highly variable and reflects a competition between Pavlovian reactions and instrumental actions. Here we exploited the…

We examined whether self-restraint in early childhood predicted individual differences in 3 executive functions (EFs; inhibiting prepotent responses, updating working memory, and shifting task sets) in late adolescence in a sample of approximately 950 twins. At ages 14, 20, 24, and 36 months, the children were shown an attractive toy and told not…

One central aspect of children's behavior in play and in situations of response uncertainty may involve the degree to which the child considers available information and forms a plan to guide behavior. Twenty-five boys and 25 girls, aged 27 months, were observed in a 30-minute free play session in which mobility and time spent in sustained…

The main experimental hypothesis of this study, that high sensation seeking subjects would be characterized by a significantly greater number of escape attempts than low sensation seeking subjects, has been strongly supported. (Author)

The present study examines the reactions to injustice between individuals as a function of the race and sex of the subject. Two contrasting hypotheses derived from research on altruism and personality differences indicate that white females/black males and white males/black females differ in their response to inequity. The study supports the…

This paper presents a critical review of empirical and theoretical treatments of group reaction to attitudinal deviancy. Inspired by Festinger's (1950) ideas on resolution of attitudinal discrepancies in groups, Schachter (1951) conducted an experiment that has greatly influenced subsequent research and theory concerning reaction to attitudinal…

Attempts to relate psychological reactance and conformity and concludes that the social situation and personality factors necessarily play a part in specifications of the psychological reactance concept. (MB)

The study makes use of Rotter's (1966) hypothesis that there are consistent individual differences between people who believe in the internal control of reinforcement and those who believe in the external control of reinforcement. Students who are "internals" will believe that their behavior controls academic successes and failures and may,…

The pleasure-arousal hypothesis predicts an interaction between pleasure and arousal levels in determining approach-avoidance, such that approach increases with arousal in pleasant settings and decreases with arousal in unpleasant settings. Results support this hypothesis. (Author)
