PERCEPTIONS OF RELATIONAL AND PHYSICAL AGGRESSION AMONG COLLEGE STUDENTS: EFFECTS OF GENDER OF PERPETRATOR, TARGET, AND PERCEIVER

This study examined gendered perceptions of relational and physical aggressive behaviors and personal experiences with both types of aggression. Prior research suggested that physical aggression by males and relational aggression by females would be perceived most negatively. College students (186 female, 128 male) rated the acceptability and harmfulness of aggression in scenarios in which type of aggression and perpetrator and target gender were varied. As predicted, relational aggression by female characters and physical aggression by male characters were rated as less acceptable and more aggressive/harmful than the same behavior by the other gender. Thus, expectations regarding the gender-appropriateness of aggression appear to affect perceptions of such acts. Despite popular conceptions that females use and are harmed by relational aggression more than males, there was no gender difference in experience with relational aggression, nor were female targets viewed as more harmed by such aggression than their male counterparts.     

AIRA: Measurement of adolescents’ judgments regarding intentions to respond to physical and verbal aggression

The current study utilized a structural equations approach in developing an instrument to investigate adolescents’ (N = 510; 9th–12th graders) judgments about the likelihood that they would actively respond to a witnessed aggressive situation. Two aggressive subscales were developed: physical and verbal. The instrument controlled for the relationship (acquaintance vs. friend) of the witness to the perpetrator and to the victim involved in the event. Results provided evidence for a domain approach to judgments about active responses to aggression. Furthermore, as predicted, the factors of gender, age, relationship of the witness to both the victim and the perpetrator, and aggressive situation influenced adolescents’ judgments. Regardless of whether the perpetrator and the victim were acquaintances or friends of the witness, younger males indicated that they were less likely to respond to acts of physical aggression than were adolescents in the other three groups. In contrast, when acquaintances were involved in situations involving verbal aggression, younger males were less likely to respond than were younger females. When the perpetrator and the victim were friends of the witness, females, regardless of age, were more likely than males to respond to verbally aggressive acts. Aggr.

Social sanction and threat explanations of gender effects on direct and indirect aggression

The present study examined two explanations for gender differences in expression of direct and indirect aggression. The social sanction model suggests that aggressor and target gender effects may be accounted for in terms of social sanctions against behaving aggressively; indirect aggression is the likely outcome of inhibitions against expression of direct aggression. The threat argument suggests that high levels of direct aggression in male‐male dyads as well as apparent inhibitions against harming females might be accounted for by the fact that males are more threatening targets than are females. Research participants completed a questionnaire measure of direct and indirect aggression twice, once with reference to their behavior toward a same‐gender target and once with reference to their behavior toward an other‐gender target. Although most direct aggression was reported by male aggressors toward male targets, gender of target did not relate to indirect aggression. Males reported approximately equal levels of indirect and direct aggression. Although females reported using more indirect than direct aggression, they did not differ from males in their reports of the frequency of use of indirect aggression. These results provided some support for both models of gender effects on human aggression and suggest the appropriateness of a relatively complex model of gender effects on aggression. Aggr.

Relational aggression in young adults' friendships and romantic relationships

This study examines young adults' experiences with relational aggression among friends and romantic partners. Results suggest that relational aggression occurs more frequently among romantic partners than among friends. A gender difference in relational aggression emerged in the romantic context (females were more aggressive), but no gender difference was found in the friendship context. Relationship exclusivity and normative beliefs about relational aggression predicted aggressive behavior across contexts, while rumination predicted relational aggression in the romantic context but not in the friendship context. Implications of these findings, as well as directions for future research, are discussed.     

Ethnicity,gender, and evaluations of aggression

In order to investigate some of the ways in which ethnicity and gender influence interpretations of aggression, 363 Anglo and Hispanic university students responded to a questionnaire soliciting their evaluations of aggression in three situations. Consistent with previous research and with the stereotype of machismo, Hispanics, particularly Hispanic males, were more likely to endorse some aggressive behaviors than Anglos. However, the same pattern of gender influences emerged for both ethnic groups. As predicted, males were more aggressive and more supportive of fighting back and punishing an aggressor than females, whereas females were more likely to show self-control about aggression and to endorse restraint. Respondents, particularly males, said that they would behave more aggressively toward a male, and they encouraged a male to behave more aggressively. These results are consistent with the social constructionist view that performance and evaluations of aggression are largely influenced by cultural factors. © 1995 Wiley-Liss, Inc.     

Sex,race, and experiences of aggression

Most previous research on sex differences in experienced aggression has confounded the sex of the aggressor and of the target by considering married or dating couples. In the present study, black and white male and female college students were asked about specific acts of aggression which they had received from or directed toward a male or female. As predicted, males were likely to have both received and exhibited more forms of aggressive behavior, although females were somewhat more likely to have been honked at, to have been forced by a male to have sex, and to have slapped someone. Few racial differences were found, but it appeared that blacks might have been relatively more likely to exhibit physical aggression and whites to exhibit nonphysical aggression. Some differences were found in specific behaviors directed toward and received from males and females, but in general subjects said that they received more aggressive behaviors than they directed toward others. © 1992 Wiley-Liss, Inc.     

Team Sports Players' Observed Aggresion as a Function of Gender, Competitive Level, and Sport Type

This study aims at examining observed aggression in team sports as a function of gender, competitive level, and sport type. It was hypothesized that (a) male players display more aggressive behaviors than female players, (b) aggressive behaviors increase when competitive level rises, and (c) gender difference in observed aggression is depending on sport type. One hundred and eighty games, equally shared among males and females, soccer and handball, and departmental, regional, and national competitive levels were recorded on videotapes and observed using a grid to differ instrumental from hostile aggressive behaviors. The results revealed that male players always display more aggressive behaviors than female players, whatever the sport, the competitive level or the nature of the observed aggression; instrumental aggressive behaviors increase and hostile aggressive behaviors decrease when competitive level rises; and the gender difference appears larger in handball than in soccer.     

Gender,the Perception of Aggression,and the Overestimation of Gender Bias

The purpose of this study was to investigate how the gender of aggressor, target, and observer influences the perception and evaluation of aggression. One hundred seventy-one university students (predominantly White) read 1 of 8 vignettes that described an aggressive act. The aggressor–target gender combinations and the aggressive act were varied. Data did not support the hypothesis that, because of the impact of gender stereotypes, participants would perceive more aggressiveness in men's aggression than in women's aggression. Participants rated women's aggression as more acceptable than men's aggression, and male participants considered the aggression more acceptable, apparently because they saw the act as less aggressive. In addition, participants estimated how most men/women would perceive and evaluate the aggression. Results suggest that people overestimate how biased others are toward members of their own gender.     

Gender and aggression I: Perceptions of aggression

To investigate how gender and ethnicity influence evaluation, perceptions, and stereotyping of aggression, two studies were conducted with 115 college students (56% male; 50% Anglo and 26% Hispanic) and 79 individuals (72% male; 92% Anglo) who worked on a military base. Participants were asked to respond to four scenarios depicting aggressive interactions in which the gender of the protagonists varied, give their perceptions of 25 potentially aggressive incidents, and answer questions concerning stereotypes of gender related to these incidents and personal aggressive behaviors. Consistent with previous research on gender and aggression, both studies found that the aggressor, target, and respondent all affected perceptions of aggression and likelihood of aggressive behaviors. Aggression from a male and aggression directed towards a female were particularly likely to be evaluated negatively. Age and educational level were both negatively related to tolerance for aggression, and Anglo vs. Hispanic ethnicity was also associated with perceptions of aggression.We would like to thank Angela Bennett, Gail Bliss, Kayleigh Carabajal, Julie Depree, Carmen Gonzales, Deborah Good, Scott Griffin, Gladys Herrera, George Selix, Ruth Tangman, and Jon Woodland for their assistance with the development, distribution, and coding of the questionnaire.     

Aggressive behavioral characteristics,hormones, and sexual orientation in men and women

Aggressive behavioral characteristics were assessed in groups of men and women by a self-report instrument, the Aggression Inventory, in which adult males reported more physical and verbal aggression than did females. Furthermore, males had higher scores on measures of impulsiveness and lack of frustration tolerance than did females, while women were more likely to avoid confrontation. In a second study, groups of male and female homosexuals and heterosexuals completed this Aggression Inventory after having blood samples taken to assay resting levels of testosterone (T) and estradiol (E). Groups of subjects within each gender were closely matched in terms of age, education, and vocational interests. Women were matched for the same time in their menstrual cycle (early follicular phase). Among men, homosexuals were indistinguishable from heterosexuals on all measures of aggression. Lesbians did not differ from heterosexual women on any aggression subscale except physical aggression, in which the homosexual women had lower scores. T and E were positively correlated with several indices of aggressive behavioral characteristics in men but were negatively correlated with those same measures in women.     

Video Game Violence and the Female Game Player: Self‐ and Opponent Gender Effects on Presence and Aggressive Thoughts

Adding depth and breadth to the general aggression model, this paper presents three experiments that test the relationships among user and opponent gender representation, opponent type, presence, and aggressive thoughts from violent video game play. Studies 1 and 2 suggest that females experience greater presence and more aggressive thoughts from game play when a gender match between self and game character exists. Studies 2 and 3 indicate that playing against a human opponent (rather than a computer) increases aggressive thoughts. Finally, although Studies 1, 2, and 3 indicate that playing as a female against a male opponent increases aggressive thoughts, Studies 1 and 2 suggest that playing as a male against a female opponent consistently and significantly decreases aggressive thoughts.     

Intersexual aggression and male sexual activity in captive rhesus macaques

Rape has been posited to be an outgrowth of male reproductive strategies. Forced copulations may have evolved as a consequence of the low parental investment made by males in producing and raising offspring. We designed a laboratory experiment which paired rhesus macaque males with females in order to assess the influence of intersexual aggression on male sexual activity. Younger and older adult males had comparable levels of sexual behavior, but younger males were more aggressive towards females than were older males. In addition, females threatened younger males more than older males. Male attacks on females did not result in sexual intercourse. On the contrary, a negative correlation existed between male aggression towards females and male success at achieving intromissions. Female aggression towards males appeared to be an effective tactic which reduced the chances of sexual intercourse. We conclude that intersexual aggression acts either as a mechanism of dominance assertion or as a means to increase spatial distance between individuals. These data do not support the idea that rape in humans has an evolutionary foundation derived from male reproductive strategies.     

The Two Worlds of Aggression for Men and Women

The purpose of this research was to assess differences in the nature of physical aggression experienced by men and women. Random digit dialing with Computer Assisted Telephone Interviewing was used to obtain a sample of 1,753 Ontario adults aged 18–60 (response rate of 67%). This method of sampling obtains respondents who reflect the ethnic and social diversity of Ontario. Respondents were asked to describe the most recent incident of physical aggression in which they had been personally involved during the past year. Most incidents reported by females were with a male opponent, usually a spouse, partner, or friend, did not involve alcohol consumption, resulted in high negative emotional impact, and pertained to jealousy. Incidents reported by males tended to be with other males, friends or strangers, in bars or public places, and involved four or more participants who had been drinking. Incidents involving only men had lower emotional impact on respondents and included more punching, threatening, and insulting behavior compared to incidents involving other gender combinations. These results are discussed in terms of the implications for violence generally and the importance of addressing male-to-male aggression and factors that foster this form of aggression.     

Emotional arousal and gender differences in aggression: A meta‐analysis

This meta‐analysis investigated the possibility that gender differences in aggression, and the variability in these differences, are a function of gender differences in the regulation of arousal generated in emotionally evocative contexts. The sample of studies for this analysis was based on an exhaustive search of the relevant research reports from 1965–1999. Studies were excluded from the sample if they were case studies; investigated spousal/familial or societal violence, war, suicide, or political violence; involved clinical or deviant participants; included fewer than 10 participants; included all male, all female, all non‐Caucasian, or non‐US/non‐Canadian participants. Based on previous evidence that males may be more easily aroused by aggressive‐relevant emotional stimuli than females, and that males may have more difficulty regulating emotionally arousing states than females, we hypothesized that the magnitude of the gender differences in aggression would covary, in a nonlinear manner, with the emotional evocativeness of the study context. Consistent with our hypothesis, the magnitude of gender differences in aggression was relatively small in research contexts that appeared to produce no or large increments in emotional arousal and larger (favoring males) in contexts that appeared to produce small or medium increments in emotional arousal.

Aggressive behavior in the free-ranging rhesus monkeys of kathmandu,nepal

We present a composite sample of the aggressive behavior of free-ranging rhesus monkeys (Macaca mulatta), recorded at two temples in Kathmandu, Nepal. We analyze the total number and the rate per monkey of threats, chases, attacks, fights, and aggressive acts directed at other species (principally humans), in order to elucidate social dynamics of the troop as a whole. Our 1,506 hours of observation were divided among the four seasons; between a.m. and p.m.; and among a temple yard, two parklands, and a forested garden. We found seasonal patterns to be the most important correlates of aggressive behavior. Habitat was a modulating influence, and time of day was the least important factor. Rates of aggression were generally higher per male monkey than per female. In terms of total aggression recorded, however, females instigated significantly more than males, both in encounters between monkeys and in aggression against other species. This finding is consistent with the females' greater numbers in the troop and with their lifelong membership in the troop. Analysis of behavior by social groups, rather than by individual rates, points up the iomportance of adult females and their social stability in troop behavior.     

70-kHz vocalizations by male mice do not inhibit aggression in lactating mice

Two experiments investigated the relationship between adult male 70-kHz vocalizations and aggression by lactating female mice (Mus domesticus). Intact, vocalizing males, surgically devocalized males, and naturally nonvocalizing males were used to assess the effects of high frequency vocalizations on maternal aggression. The emission of high frequency vocalizations promoted aggressive behavior by the females. In both experiments, lactating females attacked the vocalizing males more rapidly and showed a higher incidence of aggressive behaviors toward these males than they did to the nonvocalizing male. We suggest that these vocalizations are only one of many situational cues that the female uses to determine her final behavioral response.     

Female behavior in populations of mice in the presence and absence of male hierarchy

Female aggression may be the regulator of population size in small mammals. Freely growing populations of house mice showed several differences in aggressive female behavior in the presence and the absence of a male hierarchy. Territoriality in females and not in males appeared to maintain social order and regulate population density. Certain females were seen patrolling and guarding the territory and chasing and fighting with both male and female intruders. These females did not fight amongst themselves, suggesting that they were not fighting for rank (as do the males) but for territory. Although these aggressive females produced young, the pups were neglected, and few were weaned. The non-aggressive females were the successful breeders. Aggression by the females only occurred when there was reproduction and increased densities. Assembled females with no males present never show this aggression. The occurrence of “male-type” behavior became most apparent when the males were removed at peak population densities. The removed males were then castrated and injected with testosterone cyprionate. Doses were increased by population cage, and therefore all males returned to each freely growing population were given the same dose. The males given oil placebo injections showed no return of a male hierarchy and the females showed high levels of aggression toward them. Males injected with testosterone cyprionate showed return of male aggression and fighting and mounting of females. But the new “dominant” females continued their patrols and chased males away from their territories and did not permit these males to mount. Male-male fighting consisted primarily of frontal attacks to the face and roll and tumble fights. Female-male aggression consisted primarily of attacks to the posterior region targeted at the base of the tail and the genitals of the male. The males were rarely seen attacking females and then only during mating. Females only attacked each other in defense of their territories.     

Men who target women: specificity of target, generality of aggressive behavior

Two studies examined the effects of individual differences identified by the Confluence Model of aggression against women [Malamuth Linz, Hevey et al., 1995] and the General Aggression Model [GAM: Anderson and Carnagey, 2004] as predictors of male-on-female aggression. Study 1, a correlational study, found that hostile masculinity predicts self-reported sexual aggression independently of nonsexual aggression against women, and is itself predicted by proneness to general hostility, masculine gender role stress, and violent attitudes toward women. Furthermore, hostility toward women independently predicted sexual and nonsexual aggression against women, above the effects of general attitudes toward violence and general levels of hostility and aggression. Study 2, an experimental study, found that under high provocation, high hostility toward women predicted increases in male nonsexual aggression against women and slight decreases in male aggression against men. This effect remained significant even after controlling for general attitudes toward violence and for general levels of hostility and aggression, indicating that males who are highly hostile toward women specifically target women and that their aggression toward women generalizes beyond sexual aggression. The findings are discussed in terms of a model that integrates the Confluence Model with GAM.     

Social‐cognitive mediators of the relation of environmental and emotion regulation factors to children's aggression

Tested a theoretical model in which social cognitions about aggression partially mediated the relation of environmental and emotion regulation factors to children's aggressive behavior. An ethnically diverse sample of 778 children (57% girls) in grades 4–6 from both urban and suburban schools participated. Measures included exposure to aggression (seeing/hearing about aggression, victimization), emotion regulation (impulsivity, anger control), social cognitions about aggression (self‐evaluation, self‐efficacy, retaliation approval, aggressive fantasizing, caring about consequences), and aggressive behavior. Results supported the hypothesis that social cognitions mediate the relations of exposure to aggression and anger control to aggressive behavior. Also, social cognitions about direct and indirect aggression differentially predicted the respective behaviors with which they are associated. That is, social cognitions about direct aggression were mediators of direct aggressive behavior, whereas social cognitions about indirect aggression were mediators of indirect aggressive behavior. Finally, gender moderated the relations among the variables such that for girls, retaliation approval beliefs were a strong mediator, whereas for boys, self‐evaluation was more important. Aggr.

Friendly fire: Longitudinal effects of exposure to violent video games on aggressive behavior in adolescent friendship dyads

Research on gaming effects has focused on adolescence, a developmental period in which peer relationships become increasingly salient. However, the impact of peers on the effects of violent gaming on adolescents has been understudied. This study examined whether adolescents’ exposure to violent video games predicted their own and their friend's aggression one year later. Among 705 gaming adolescents, 141 dyads were identified based on reciprocated best friend nominations (73.8% male, M_age = 13.98). Actor‐Partner Interdependence Models indicated that adolescent males’ (but not females’) exposure to violent games positively predicted the aggression of their best friend 1 year later. This effect appeared regardless of whether the friends played video games together or not. The study illustrates the importance of peers in the association between violent gaming and aggression.
