Proactive and reactive aggression in early adolescence as precursors to anti- and prosocial behavior in young adults

Three groups of adolescents who were 14 years old in 1974 were formed on the basis of peer nominations and teacher ratings in an ongoing longitudinal study: 1) reactively aggressive (REA) individuals who displayed reactive, that is, self-defensive aggression but not proactive aggression (43 boys, 35 girls); 2) proactively aggressive (PROA) individuals who attacked another person without a reason (56 boys, 35 girls); and 3) nonaggressive (NONA) individuals who were low in proactive and reactive aggression (48 boys, 45 girls). The groups were compared at ages 8, 14, and 27 in variables representing the constructs of a two-dimensional model of emotional and behavioral regulation. The REA Ss were characterized by higher self-control, especially constructiveness, at each age and better adult adjustment than the PROA Ss. The PROA males were prone to externalizing problems and criminality in adulthood, whereas the PROA females were prone to internalizing problems and neuroticism in adulthood. Both exhibited conduct problems in adolescence, and became heavy users of alcohol in adulthood. The PROA Ss had more children at age 27 than the other Ss. © 1996 Wiley-Liss, Inc.     

Children's reasoning about responses to peer aggression: Victim's and witness's expected and prescribed behaviors

This research examined children's reasoning about expected (i.e., what a peer would do) and prescribed (i.e., what a peer should do) responses to unprovoked, intentional aggressive actions in two contexts: as a victim of such a transgression and as a witness to the incident. Physical harm and property damage items were used in a structured interview format. There were 90 subjects drawn from three elementary school grades (2nd, 4th, and 6th). Children differentiated between the expected and prescribed responses of peers and significant developmental differences in children's evaluations were found. Although the majority of the subjects in all grades denounced retaliation on the basis of concerns about others' welfare, older children stated that peers were likely to retaliate against the perpetrator nonetheless. Across different contexts, older children's responses appeared to reveal a greater independence from authority in negotiating peer interactions. In evaluating the witness's responses to aggressive acts, younger children's expected and prescribed responses were less disparate than that of the older children. The utility of including different vantage points of the child in examining children's social reasoning about aggression and the application of the present findings to social information-processing models are discussed. © 1996 Wiley-Liss, Inc.     

Salivary testosterone and self-report aggressive and pro-social personality characteristics in men and women

Measures of salivary testosterone and the personality dimensions of aggression and pro-social behavior were obtained in 306 (155 male and 151 female) university students. Each participant provided two samples of saliva and completed ten self-report personality scales from multiple inventories. A factor analysis of the personality scales produced two factors, an aggression factor and a pro-social behavior factor. Men averaged five times the amount of salivary testosterone as women (99 pg/ml vs. 18.5 pg/ml) and rated themselves as more aggressive and less nurturant. Within each sex, testosterone was positively correlated with aggression and negatively correlated with pro-social personality. Structural equation modelling analyses suggested that a direct effect model best described the relationship between salivary testosterone and the latent personality dimensions of aggression and pro-social behavior. © 1996 Wiley-Liss, Inc.     

EVidence for dorsolateral and orbital prefrontal cortical involvement in the expression of aggressive behavior

Numerous studies have implicated the role of the prefrontal cortex in the expression of aggressive behavior. However, the nature of this relationship remains poorly understood. As such, the purpose of this article is to review both the animal and human literature pertaining to prefrontal cortical functioning and aggression in an attempt to help clarify this relationship. Particular attention is paid to differentiating the functions of the dorsolateral and the orbital regions of the prefrontal cortex in the expression of aggression. Evidence was garnered from four different types of studies: 1) those examining aggressive behavior in animals following ablations to the prefrontal cortex; 2) those examining aggressive behavior in humans following surgical and accidental lesions to the prefrontal cortex; 3) those examining prefrontal cortical functioning in individuals with psychiatric disorders characterized by aggression; and 4) those relating prefrontal cortical functioning to human aggressive behavior in laboratory situations. The general conclusion of this article is that the dorsolateral region of the prefrontal cortex is more likely to be involved in the expression of physical aggression whereas the orbital region is more likely to be involved in the expression of what is termed herein “disinhibited-nonaggressive” behavior. © 1995 Wiley-Liss, Inc.     

Sexual jealousy in young women and men: Aggressive responsiveness to partner and rival

Two studies compared judgments about aggressive components of jealous reactions to the partner and to the rival, specifically, emotional (anger), cognitive (blame), and behavioral components. The first study randomly assigned 172 young women and men to two questionnaires on jealous reactions to mild (flirting) and serious (cheating) transgressions. One questionnaire assessed standards for appropriate behavior and perceptions of how people usually react. The second questionnaire asked people to report how they had reacted or, if not experienced with a sexual transgression, how they would react. The second study asked 113 people to imagine a situation in which they knew their partner had been sexually unfaithful. There were three major findings that were interpreted in the context of courtship, a time when attention is focused on the qualities of one's potential long-term partner. First, the jealous individual's anger and blame were focused more on the partner than the rival. Second, mean anger and blame scores given the partner were well matched. In contrast, the rival received more anger and blame than deemed appropriate and considerably more anger than blame. These data suggest that, in the context of courtship, a rival is not simply a competitor. Third, men were more inclined to think about aggressive action against the rival but women were more emotionally and behaviorally reactive to the rival. The latter result implies that, in the context of competition for an established romantic partner, a rival is more salient for women than for men. © 1993 Wiley-Liss, Inc.     

A comparison of skill-building and desensitization strategies for intervention with aggressive children

Social skills training and desensitization interventions were conducted with 41 institutionalized aggressive children aged 7–13. Subjects were randomly assigned after blocking by aggression and cooperative play to either of the treatments. Dependent measures were direct observations of playground play and teacher ratings. Subjects in the social skills program mastered the basic cognitive skills presented to them. Observational data indicated that both groups experienced marked reduction in aggressive behavior and increases in cooperative play. The social skills training intervention engendered incremental improvement in aggression in comparison to the desensitization condition. However, none of the behavioral changes evident in the observations were reflected in teacher ratings.     

Showing-off behaviour of nursery children

Assertive behaviours like showing-off have an important role for a child in getting attention from other children in a class without being aggressive. This study presented the showing-off behaviour in an English nursery school, and later it was discussed in comparison with that in the German kindergartens reported by Hold-Cavell. As a result, the English children performed showing-off behaviours at only one-half the frequency of German children. No sex difference was seen in either showing-off or physical aggression in the nursery class. The frequency of showing-off did not correlate with that of physical aggression; this result is discussed in terms of Hinde's motivational postulate. Showing-off behaviour is deserving of the further studies cross-culturally and onto-genetically.     

Person perception when aggressive or nonaggressive sports are primed

Previous research investigating the factors contributing to sports spectator violence has focused primarily on conscious processes such as the disinhibiting effects of aggressive models and physiological arousal. The current research borrows a methodology from social cognition work to examine the role of passive, category accessibility effects on fan hostility. Prior research has indicated that as a schema becomes more accessible in memory, the use of it to encode subsequent information is increased. It was therefore hypothesized that individuals for whom the category of hostility had been unobtrusively primed with aggressive-sports names (e.g., boxing) would rate an ambiguous target person as more hostile and as more likely to prefer hostile activities relative to persons who were primed with sports names which were not associated with violence (e.g., golf). The results supported the hypotheses, with subjects who were primed with aggressive-sports rating an unrelated target person's behavior as significantly more hostile and as more likely to prefer aggressive activities relative to subjects exposed to sentences containing references to nonaggressive-sports. Discussion includes the potential ramifications for spectator aggression at sporting events.     

Attributional style of the mother as a predictor of aggressive behavior of the child

The association between the life orientation and attributional styles of a mother and the aggressiveness of her child were studied in 61 mothers and their children, 23 boys and 38 girls, mean age 6.6 years (range 4–13 years). The mother's life orientation and attributional styles were established during interviews using the life-style questionnaire, and a child's aggressiveness was evaluated by the mother using the Health Examination Survey. The factors assessing life orientation were lack of personal control, causal unstability, internal locus of causality, personal responsibility, and democratic educational attitudes. The mother's personal responsibility and internal causal attributions were related to nonaggressiveness in the child, whereas mothers with a lack of personal control were likely to have aggressive children. Educational attitudes were of no importance. The results showed no sex- or age-related variance.
