Women's aggression: An African case study

Theories of human aggression tend to emphasize aggression as a male phenomenon. An ecological approach to aggression implies that females ought to be aggressive when confrontation is a viable means of attaining scarce resources. In modern Zambia, intrafemale aggression occurs at the individual and socioeconomic class levels. At the individual level, aggression occurs between women for a specific man or his economic resources both within households and beyond their boundaries. At the class level, elite and poor women combine forces to victimize subelite women. Both levels of aggression involve competition over the scarce resource of socially desirable men and their support. Competition is due to the unequal access of the genders to opportunities for labor-force participation and hence different positions in the stratification system, the desire for hypergamous marriage, marital instability, changing role expectations, and the increased dependency of women on men.     

The pain-aggression relationship and its expression in naturalistic settings

Relationships between environmental events and aggression are briefly reviewed. Response-independent pain is a fundamental antecedent environmental cause of attack. Aggression-contingent pain decrease causes further attack strengthening, while pain increase following aggression can decrease attack and foster escape and avoidance behavior. Recent experiments that have questioned the pain-aggression relation and proposed, in the alternative, a pain-defense relationship are discussed. It is argued that this contradiction results from observational difficulties in naturalistic settings, discordance between field and laboratory terminology, substitution of behavioral taxonomy in the place of functional analysis, incomplete understanding of previous findings, and an absence of essential experimental control observations.     

Effects of reactivity to dorsal stimulation and social role on aggressive behavior in laboratory rats

Rats were selected on the basis of reactivity to dorsal tactile stimulation and then tested in a resident-intruder paradigm. While reactivity of residents did not influence the occurrence of agonistic behaviors or wounding of residents and intruders, reactivity of intruders did affect offensive and defensive patterns of interactions and the wounds sustained by residents and intruders. Subsequent to resident-intruder testing, rats were tested for shock-induced aggression. The pattern of the results and the results of additional experiments demonstrated that resident-intruder experience could affect subsequent shock-induced aggressive behavior.     

Comparison of agonistic behavior in individually-housed male mice with those cohabiting with females

Videotape recordings of male mice group-housed, individually-housed and cohabiting with females, were rated for their agonistic behavior in a “standard opponent” test. Previously mated male mice showed more fighting than isolated or grouped males. Marked differences in other social and non-social behaviors, which could not be accounted for in terms of increased fighting, were not evident. These results suggest that agonistic behavior may be usefully studied by examining male mice that have cohabited with females. One obvious advantage is that such mice cannot be dismissed as being “socially deprived,” as is sometimes claimed for individually-housed mice. Other advantages are that aggressiveness is induced quickly, at high levels, and the mice appear very sensitive to hormone manipulation following castration.     

Interspecific aggression and reactivity in rats: Effects of selective raphe lesions and additional olfactory bulb ablation

Large depletion of brain 5 HT has been shown to induce mouse-killing behavior in the rat. Selective lesions of the raphe nuclei have been investigated in order to determine whether the various components of the 5 HT system exert some specific control over this aggressive behavior. Electrolytic lesions of the dorsal or the median raphe nucleus do not induce mouse killing, whereas combined lesions of these nuclei elicit this behavior in about 40% of naive rats. Consequently, it appears that serotonergic neurons originating in the dorsal and median raphe nuclei work synergistically in mediating inhibitory control over mouse-killing behavior. Loco-motor activity is increased in novel environments by each of the selective lesions and to a larger extent by combined raphe lesions; 24 hours activity in resting conditions is unchanged during the light period, and increased during the dark period of the daily cycle by the various lesions. As it has been shown previously that hyper-activity in response to novelty following raphe lesions is not directly related to the 5 HT decrease in the brain, it appears that interspecific aggression and motor responsiveness must not be dependent on the same neural substrate within the raphe nuclei. The raphe lesions do not facilitate the elicitation of mouse killing by further olfactory bulb ablations, in contrast to earlier results where bulbectomy facilitated the induction of this behavior by raphe lesions.     

攻击者的注意偏向与归因偏向及其关系

在攻击者的认知偏向中,注意偏向与归因偏向尤为引人注目。攻击者常偏向于注意敌意性的刺激,并会对模棱两可的情境作出敌意性的解释。二者的关系存在注意优先模型与解释优先模型两种可能性,注意优先模型认为注意过程先于解释过程,解释优先模型则相反。两种假设各有论据支持,而攻击者注意偏向与归因偏向的关系尚无定论。今后的研究当改进实验方法、运用多种技术从理论和应用两方面更深入地探讨攻击者的这二种偏向及其关系。     

罗夏墨迹测验在西方的发展历史与研究现状

历史上罗夏墨迹测验（RIM）一直被视为投射测验而用精神分析的理论解释它,使其偏离了客观化的发展方向。综合罗夏系统则又回归到了实证的研究道路。综合系统仍视之为一个不完全结构化的、间接的测量方法,因此在人格研究中有独特的作用。关于RIM虽然仍有争议,但其科学研究价值已基本得到公认,目前要做的工作是发展它和完善它     

Interpersonal Relationships and Sex Differences in the Development of Conduct Problems

This article investigates the role of interpersonal relationships in shaping sex differences in the manifestation, etiology, and developmental course of conduct problems and their treatment needs. The review examines whether: (1) Girls conduct problems are more likely than boys to manifest as a function of disrupted relationships with caretakers and peers; (2) For girls more than for boys, the outcomes of conduct problems in adolescence and adulthood, and related treatment needs, are more likely to be a consequence of the quality of interpersonal relationships with others, particularly opposite-sex peers and partners. Evidence reviewed suggests that boys and girls share many similarities in their expression of conduct problems, but that a relational perspective does unify important differences. There is fair evidence that girls with conduct problems are more likely to come to the attention of authorities because of chaotic, unstable family relationships, and to express antisocial behavior in the context of close relationships; there is stronger evidence that the course and outcomes of conduct problems in females versus males pertain to interpersonal relationship impairments. Those sex differences map onto specific differences in treatment needs. Further empirical testing of the proposed relational model is indicated.     

Aggression,friendship, and reconciliation in Russian primary schoolchildren

Aggression and reconciliation were studied in a group of 6‐ to 7‐year‐old Russian schoolchildren using the matched control approach and the two methods used in primate ethology—the postconflict period–matched control period and the time rule methods. Aggression was found to be positively correlated with friendly behavior at the dyadic level. It is demonstrated that children, like nonhuman primates, tend to reconcile within 1 min after the conflict. Victims tend to redirect aggression at other individuals. No effect of gender on reconciliation was found. The reconciliation tendency is less expressed in friends than in children who are not friends. A new reconciliation measure is introduced, and an operational definition of friendship is suggested. Aggr. Behav. 25:125–139, 1999. © 1999 Wiley‐Liss, Inc.     

Social and personal determinants of workplace aggression: Evidence for the impact of perceived injustice and the Type A Behavior Pattern

Four hundred fifty‐two employed persons rated the frequency with which they had been the victims of a wide range of aggressive actions at work. In addition, they also rated the frequency with which they themselves had aggressed against others in their workplaces. Three hypotheses were investigated: (1) covert forms of aggression, in which aggressors seek to conceal their identity from target persons, are significantly more frequent in workplaces than overt forms of aggression; (2) the greater the perceived injustice reported by employees, the greater their tendency to engage in workplace aggression; and (3) the higher individuals' scores on a measure of the Type A Behavior Pattern, the greater their reported frequency of engaging in various forms of workplace aggression. Results offered support for all three hypotheses. In addition, several demographic variables (participants' age and gender; the physical location of their workplaces) were also found to play a role in the occurrence of workplace aggression. Together, these findings were interpreted as underscoring the importance of establishing close conceptual links between research on workplace aggression and basic research on human aggression. Aggr.
