Sex and aggression during rhesus monkey group formation

Observational data from 16 newly formed social groups of rhesus monkeys were analyzed to identify patterns of behavior that correlated with the frequency and intensity of aggression directed toward females. The results revealed significant correlations between heterosexual behavior and female-female noncontact aggression and between female homosexual behavior and female-female contact aggression. The role of female homosexual behavior and its relationship to aggression in the formation of new groups is discussed.     

The Relationship Between Religious Orientation,Right-Wing Authoritarianism,and Implicit Sexual Prejudice

The relationship between intrinsic, extrinsic, and quest religious orientations, right-wing authoritarianism (RWA), and implicit and explicit attitudes toward homosexual individuals were examined within a sample of predominantly Protestant college students in the United States. Implicit attitudes were measured with the Implicit Association Test, a computer program that recorded reaction times as participants categorized symbols (of heterosexual and homosexual individuals) and adjectives (good or bad words). Participants displayed fairly negative implicit and explicit attitudes toward homosexual individuals (i.e., sexual prejudice). Intrinsic religious orientation uniquely predicted increased explicit sexual prejudice (when extrinsic, quest, and impression management were statistically controlled), and RWA appeared to mediate this effect. In contrast, the positive relationship between intrinsic religion and implicit sexual prejudice did not disappear when controlling for RWA. Although RWA seemed to be related to self-reports of prejudice, intrinsic religious orientation was uniquely related to automatic negative attitudes toward homosexual individuals.     

Physical aggression: Effects of ethnicity of target and directionality of aggression

Physical aggression of members of a powerful majority ethnic group against an opponent either from a powerless and discriminated against minority or from their own group was tested as a function of aggression directionality and aggressor's attitudes. It was hypothesized that under bidirectional aggression where the opponent could aggress as well, members of the powerful majority group would adjust their aggressive responses to that of their opponent's regardless of his ethnic origin and regardless of aggressor's attitudes. However. under unidirectional aggression where the opponent was powerless, it was expected that those subjects who held unfavourable attitudes toward members of the minority group would be more aggressive against an opponent of that group than against an opponent of his own ethnic group. Subjects who had neutral attitudes would be equally aggressive toward all opponents. Ninety-six 11th grade vocational high school male students of Western origin, were given the opportunity to administer electric shocks to an opponent who was either of Western or Oriental origin in a competitive situation, Subjects were selected according to their attitudes toward Oriental Jews. Half expressed negative attitudes, the other half neutral attitudes. Half of the subjects expected their opponent to reciprocate shocks, the others did not. Contrary to expectations it was found that the attitudes of subjects of Western origin towards Orientals did not effect their aggressive behaviour. When aggression could not be reciprocated, all subjects were more aggressive toward an opponent of Oriental than of Western origin. The findings showed that when aggression was bidirectional, all subjects adjusted their aggressive behaviour, to their opponents'. However, they were less aggressive towards an opponent of Oriental than of Western origin.     

Effects of Victim Gender and Sexuality on Attributions of Blame to Rape Victims

Previous research suggests that homosexual male rape victims receive more blame than heterosexual victims. In this study, we examined effects of victim gender and sexuality on judgments of victims of stranger rape by a male perpetrator. Participants read a rape vignette in which victim gender and sexuality varied, and then rated the amount of blame they attributed to the perpetrator and victim. Victims were attributed more blame if their sexual orientation suggested potential attraction to the perpetrator: gay men and heterosexual women received more blame than did lesbians and heterosexual men. Further, homophobic attitudes toward gay male victims increased the blame attributed to them: perpetrators of rape of gay men were seen as least responsible for their actions, and the character of gay male victims was seen to be a stronger contributory factor than it was for other victims.     

An aggression machine v. determinants in reactive aggression revisited

The relations between reactive aggression, situational cues, and emotion regulation were examined by means of the Pulkkinen Aggression Machine (PAM) task. In the PAM, provocation and response were systematically varied under two conditions: the impulsive aggression condition and the controlled aggression condition. In the impulsive condition, no information about the attacker was provided, while in the controlled condition the attackers were specified in terms of sex, age, and physical strength. The task was administered to 109 children aged 8 to 13 years. Boys (n = 61) and girls (n = 48), as well as subgroups of Adjusted (n = 67) and Maladjusted (n = 26) children were compared. The results confirmed earlier findings showing that there is a strong relationship between attack and response intensity. However, this relationship was consistently modified by the effects of situation and personality‐related variables. This meant that, while for the impulsive condition response intensity was closely tied to stimulus intensity, in the controlled condition this effect was modulated by the characteristics of the opponent: the more equal the opponent the stronger the retaliations displayed. The Maladjusted children reacted more intensively in the impulsive condition and to minor provocation in the controlled condition than the Adjusted children. This suggests that the intensity of the elicited aggression in the Maladjusted group was particularly dependent on contextual rather than internal control. Aggr.

Associations Between Religious Personality Dimensions and Implicit Homosexual Prejudice

Personality correlates of implicit and explicit attitudes toward homosexual and heterosexual individuals were examined within a sample of predominantly Protestant college students in the south-central United States. Implicit attitudes were measured with the Implicit Association Test, a computer program that recorded reaction times as participants categorized symbols (of heterosexual individuals and gay men) and adjectives (good or bad words). Participants also completed self-report measures of religious fundamentalism (RF), Christian orthodoxy (CO), right-wing authoritarianism (RWA), impression management (IM), and attitudes toward heterosexuals, gay men, and lesbians. Participants displayed fairly negative implicit and explicit attitudes toward homosexual relative to heterosexual individuals. Consistent with previous research, RF, CO, RWA, and IM were associated with increases in self-reported homosexual prejudice. Religious fundamentalism was the strongest predictor of a negative implicit attitude toward gay men relative to heterosexuals.     

Homosexuality,Heterosexuality, and Cross-Dressing: Perceptions of Gender Discordant Behavior

This study examined attitudes of heterosexual and homosexual males toward heterosexual and homosexual cross-dressers. It was hypothesized that heterosexual males would be equally intolerant of homosexual cross-dressers, heterosexual cross-dressers, and homosexuals who did not cross-dress, but that homosexuals would be more tolerant of noncross-dressing homosexuals than of the other two groups. It was also hypothesized that homosexual subjects, but not the heterosexual subjects, would rate the homosexual noncross-dressers as more masculine than the cross-dressers. Forty-five heterosexual and 45 homosexual male college students read stories about a character who was described as a heterosexual cross-dresser, a homosexual cross-dresser, or a plain homosexual. 83 subjects were Caucasian, 2 were Asian, and 5 were African American; about 60% of the subjects were middle class; 30% were from lower class families and 10% were upper class. Heterosexuals were much less tolerant of all three vignette characters than homosexuals, but neither group rated the characters much differently when they were labeled differently. Homosexuals, but not heterosexuals, rated the plain homosexual as more masculine than the cross-dressing characters. Results also showed that gay males with highly nontraditional attitudes toward women had higher self-esteem.     

Cognitive and physiological indices of sexual arousal in homosexual,bisexual, and heterosexual males

Cognitive and physiological indices of sexual arousal were investigated utilizing groups of homosexual, bisexual, and heterosexual subjects (ten subjects per group) who were presented both homosexual and heterosexual films and slides. The results indicated that both homosexual and heterosexual subjects were able to estimate accurately their degree of erection to the erotic stimuli. Bisexual subjects, however, showed a large discrepancy between the magnitude of actual erection and verbally reported estimates of penile tumescence. In terms of physiological arousal, the erectile responses of the homosexual and bisexual groups were indistinguishable, a finding which questions the existence of male bisexuality as distinct from homosexuality or as a different sexual orientation in males.     

Aggression Toward Gay Men as Gender Role Enforcement: Effects of Male Role Norms, Sexual Prejudice, and Masculine Gender Role Stress

ABSTRACT This study examined sexual prejudice and masculine gender role stress as mediators of the relations between male gender norms and anger and aggression toward gay men. Participants were 150 self-identified heterosexual men who completed measures of adherence to male gender role norms, sexual prejudice, masculine gender role stress, and state anger. Participants then viewed a video depicting intimate relationship behavior between 2 gay men, reported state anger a second time, and competed in a laboratory aggression task against either a heterosexual or a gay male. Results indicated that adherence to the antifemininity norm exerted an indirect effect, primarily through sexual prejudice, on increases in anger. Adherence to the status and antifemininity norms exerted indirect effects, also through sexual prejudice, on physical aggression toward the gay, but not the heterosexual, male. Findings provide the first multivariate evidence for determinants of aggression toward gay men motivated by gender role enforcement.     

Intellectual ability and aggressive behavior in nonclinical-nonforensic males

The purpose of this study was to test the relationship between IQ and physical aggression in a nonclinical-nonforensic male sample in a laboratory setting. Thirty males completed an abbreviated version of the Wechsler Adult Intelligence Scale—Revised. Aggression was measured using a modified version of the Taylor reaction-time (RT) aggression paradigm in which subjects competed on a RT task and both received and delivered shocks to a fictitious opponent in provoking and nonprovoking conditions. Provocation conditions (High and Low) were defined by the intensity of shocks the subjects received. Results demonstrated strong inverse correlations between IQ and aggressive behavior under both High and Low Provocation conditions.     

Combined Effects of Masculine Gender‐Role Stress and Sexual Prejudice on Anger and Aggression Toward Gay Men

This study was designed to examine the extent to which masculine gender‐role stress, sexual prejudice, and antigay anger collectively facilitate antigay aggression. Participants were 135 heterosexual men who completed a structured interview assessing masculine gender‐role stress, sexual prejudice, anger in response to a vignette depicting a non‐erotic male–male intimate relationship (i.e., partners holding hands, kissing), and past perpetration of antigay aggression. The results indicate that the association between masculine gender‐role stress and antigay aggression is partially mediated by antigay anger among sexually prejudiced men. These findings contribute to theoretical understanding of antigay aggression. Implications for future research and intervention are discussed.     

Inhibition and Disinhibition of Male Aggression Against Females: A Personality Moderator Approach

Three experiments examined the role of individual differences in combination with contextual factors hypothesized to moderate the level of hostility toward females evident in male participants' responses. In Study I, we manipulated survey context and examined the influence of participants' levels of rape myth acceptance (RMA) on self-reported rape likelihood. In Study 2, we examined the interactive role of target gender and participants' levels of sex guilt (SG) on aggression toward the target after exposure to an erotic film. Study 3 results suggested that high SG males have particularly negative responses to women (but not men) who enjoy erotic presentations, consistent with a "Jack-the-Ripper" interpretation of the Study 2 findings.     

What Accounts for Heterosexual Women’s Negative Emotional Responses to Lesbians?: Examination of Traditional Gender Role Beliefs and Sexual Prejudice

This study examined a pathway to heterosexual women’s experience of anger and anxiety in response to lesbian interactions. Participants were 149 18–30 year old heterosexual female undergraduates (56% African American) from a southeastern United States university. Participants completed measures of female gender role beliefs, sexual prejudice, and state affect, viewed a video depicting relationship behavior between a female–female or male–female dyad, and again completed a measure of state affect. Results indicated that traditional beliefs about women were associated with higher levels of sexual prejudice toward lesbians. In turn, higher levels of sexual prejudice predicted increased anger (not anxiety) in response to the female–female, but not the male–female, dyad. Findings elucidate determinants of heterosexual women’s anger, and potentially aggression, toward lesbians.     

The relationship between attitude,assertiveness and condom use

The Australian study investigated condom-specific assertiveness and condom use as a means of prevention infection from sexually transmitted diseases. 211 men participated including 83 homosexual men (aged 19-62 years) and 128 heterosexual men (aged 17-49) who completed a questionnaire that comprised demographic details such as age, monogamy, and sexual activity as well as attitudinal and assertiveness measures. General assertiveness was measured by the Rathus Assertiveness Schedule (RAS) which had been widely used across a wide range of social situations. Assertiveness relating specifically to situations involving condoms was measured by the Condom Assertiveness Scale (CAS). Intention to use condoms was positively related to favorable attitudes, which were related to condom-specific assertiveness for both groups. For the heterosexual men only, general social assertiveness was negatively related to attitudes toward condoms. For both groups, the condom-specific measure of assertiveness was positively correlated with attitudes toward condoms. Condom-specific assertiveness was positively related to general social assertiveness as measured by the Rathus Assertiveness Schedule for the homosexual, but not for the heterosexual men. The negative relationship between general assertiveness and attitude to condoms among the heterosexual men implies that the risk reducing behavior of condom use did not seem to accord with the perceptions of masculinity and social assertiveness among heterosexual men. Thus, female partners of such heterosexual men exhibiting negative attitudes toward condom use combined with assertiveness would have to overcome resistance to insist on the use of condoms. Recently some advertising campaigns have been directed at women. The promotion of condom use among heterosexual men has to deal with the perceptions of condom use as unmasculine behavior.     

Effects of provocation on emotions and aggression in males

The effects of provocation of emotions and human physical aggression were examined using a competitive reaction time paradigm. Fifty-four males participated in the competitive task with a fictitious opponent. Participants were assigned to two conditions, low-constant provocation and increasing provocation. Aggression was defined as the intensity of electric shocks participants selected for the opponent to receive. Negative emotions (threat, harm) and positive emotions (benefit, challenge) were assessed at four times during the experimental task. The results revealed that both aggressive responding and harm emotions differed as a function of opponent's level of provocation. There was little compelling evidence that emotions served as an important intervening variable in the relationship between provocation and aggression. Aggr.

The effects of sexual and/or aggressive film exposure on helping, hostility, and attitudes about the sexes

After viewing an aggressive, sexually aggressive, erotic heterosexual, or control film, 129 females and 135 males expressed their willingness to help and hostility toward the male or female experimenter. Males extended the least help to the experimenter following the aggressive film and expressed more positive affect than females. Erotophilic males expressed slightly less hostility toward a female than a male experimenter. Erotophiles expressed more positive attitudes toward women and toward men after viewing either the rape film shown by a male experimenter or the erotic film shown by a female experimenter, compared to erotophobes. Among erotophobes, these two experimental conditions generally produced the most negative effects on general attitudes about the sexes. Affective responses to sex variations in dominant status and to aggressivity were employed to provide explanations for these results.     

Effects of racial prejudice and race of target on aggression

Three studies were conducted to investigate the relationship between prejudice and physical aggression using the competitive reaction time paradigm. In Study 1, high and low prejudiced subjects competed against either a black or white opponent. The race of the opponent did not differentially affect the aggressive behavior of either high or low prejudiced subjects. In Study 2, high prejudiced subjects were confronted with a competitor who behaved in a nonaggressive fashion. Under these conditions, the high prejudiced subjects attacked the black target more than the white target. In Study 3, high prejudiced subjects competed against an opponent who communicated nonaggressive intentions. The subjects behaved in a nonaggressive manner toward both the black and the white target. It was proposed that prejudice facilitates indiscriminate aggression in the presence of a clear threat and selective aggression in the presence of ambiguous threat.     

The effects of hormones,Type A behavior pattern,and provocation on aggression in men

Thirty-eight male college students, classified as either Type A or Type B based on their Jenkins Activity Survey (JAS-T) scores, competed in a reaction time task that allowed them to administer shocks to an increasingly provocative fictitious opponent. Salivary testosterone and cortisol were measured both prior to and after the task. Aggression was defined as the level of shock the subject was willing to set for the opponent. The results of this study indicate that a relationship exists between endogenous testosterone levels in men and direct physical aggression. Some evidence for the moderating effects of hormones on the level of aggression expressed by Type As was observed. No direct relationship between Type A and aggression was found.     

Development and Validation of the Homophobia Scale

This study describes the development and validation of the Homophobia Scale. The scale was developed to assess the cognitive, affective, and behavioral components of homophobia. The participants (n=321 for the field trials and n=122 for test–retest reliability) were college students from a large Midwestern university. Results yielded a 25-item questionnaire consisting of three factors: a factor that assesses mainly negative cognitions regarding homosexuality, a factor that assess primarily negative affect and avoidance of homosexual individuals, and a factor that assesses negative affect and aggression toward homosexual individuals. Concurrent validity was established using The Index of Homophobia (Hudson & Ricketts, 1980). The phases of scale development and implications of the results are discussed.     

Aspects of Homophobia in Italian High Schools: Students' Attitudes and Perceptions of School Climate

This study investigated Italian high school students' negative attitudes toward gay men and lesbians and their exposure to aspects of homophobia in their schools. Female students viewed gay men and lesbians in similar ways. Male students, on the other hand, held more negative attitudes toward gay men than toward lesbians. Participants reported widespread experiences of homophobic behaviors in their schools, especially verbal abuse. Students' perceptions of a homophobic school climate and respondent sex predicted homophobic attitudes among participants. Homophobic school climate mediated the relationship between respondent sex (male) and homophobia against gay men.
