Sex differences in the contexts of extreme jealousy

Research on sex differences in jealousy using continuous measures sometimes reveals that women report more intense jealousy than men in response to both sexual and emotional infidelity. Two studies tested whether these findings might have stemmed from sex differences in the interpretation of the upper anchor of the jealousy scales (e.g., “extremely jealous”). In Study 1, women and men offered different types of exemplars when describing situations in which they felt extremely jealous. A significantly greater proportion of women than men reported feeling extreme jealousy in the context of romantic relationships. Additional results demonstrated that women and men confuse the terms “jealousy” and “envy,” although this confusion cannot account for the sex differences in the contexts of extreme jealousy. Study 2 demonstrated that the sex difference in the intensity of reported jealousy disappears if the upper anchor of the scale is modified to include specific contextual information (e.g., “as jealous as you could feel in a romantic relationship”).     

Sex differences in the events that elicit jealousy among homosexuals

When individuals are asked which event would upset them more—a partner's emotional infidelity or a partner's sexual infidelity—among heterosexuals more men than women select a partner's sexual infidelity as the most distressing event, whereas more women than men select a partner's emotional infidelity as the most upsetting event. Because homosexuals’mating psychology is unlike that of heterosexuals, the present study examined which of these two events is more upsetting in a sample of 237 Dutch homosexuals. In support of our hypothesis it was found that, whereas gay men more often than lesbian women chose a mate's emotional infidelity as the most upsetting event, lesbians more often than gay men chose a mate's sexual infidelity as the most upsetting event. In addition, analyses showed that the effect of participant sex on infidelity choice was mediated by beliefs with regard to the co‐occurrence of sexual and emotional infidelity. Apparently, with respect to choosing the most upsetting type of infidelity of their partner, homosexuals resemble heterosexuals of the opposite sex. Several explanations are discussed for this finding.     

Sex differences in jealousy: the (lack of) influence of researcher theoretical perspective

The sex difference in jealousy is an effect that has generated significant controversy in the academic literature (resulting in two meta-analyses that reached different conclusions on the presence or absence of the effect). In this study, we had a team of researchers from different theoretical perspectives use identical protocols to test whether the sex difference in jealousy would occur across many different samples (while testing whether mate value would moderate the effect). In our samples, we found the sex difference in jealousy to occur using both forced choice and continuous measures, this effect appeared in several different settings, and, we found that mate value moderated participant responses. The results are discussed in light of the controversy surrounding the presence of the effect.     

Sex drive, attachment style, relationship status and previous infidelity as predictors of sex differences in romantic jealousy

Recent research examining sex differences in jealousy suggests that more men than women tend to be distressed by sexual infidelity, and that more women than men tend to be distressed by emotional infidelity. The primary explanation for these findings is that evolution has shaped men’s and women’s responses to enhance their chances of reproductive success. However, within-sex differences are also found in terms of relative level of distress at sexual or emotional infidelity. This study examined the effect of alternative variables, particularly those associated with attachment and sexual motivations, on both between- and within-sex differences in relative distress at sexual and emotional infidelity. A community sample of 437 adults provided data using a self-report questionnaire. The results showed that sex drive was a significant predictor of distress at jealousy for both men and women, while attachment avoidance and previously being the victim of a sexual infidelity were significant predictors for men only, and relationship status was a significant predictor for women only. Overall, these findings support the evolutionary model of jealousy, and suggest that sex-specific evolved psychological mechanisms underpinning jealousy are influenced by attachment and sexual motivations.     

Sex differences in expectancy of examination results

Abstract.— Within a group of undergraduates it was found that men had higher expectancy than women in a psychology examination. Although importance of examination results for future career was positively related to expected results in both sex groups, women did not regard results as less important than men did, and the sex difference in expectancy could not be attributed differential value of examination for women and men. Whereas estimated importance of results for future career was positively related to importance of results for self-regard in the male group, no such relationship was found for women.     

Sex differences in jealousy in response to infidelity: Evaluation of demographic moderators in a national random sample

Studies examining sex differences in jealousy have often relied on student samples and were restricted to the evaluation of a selected few moderators. In this study, a nationally representative survey of American households was presented with either an actual or a hypothetical infidelity scenario (which appeared as either a forced choice or as continuous measures). Significant sex differences only emerged for forced choice measures and not for continuous measures. Importantly, this effect appeared most strongly in participants reporting reactions to an actual infidelity. We also explored a number of potential moderators of this effect. These moderators were more influential for the hypothetical than for the actual infidelity scenario. Exploratory analysis of additional demographic variables was conducted.     

Culture and gender differences in romantic jealousy

Jealousy is an intense emotion that is experienced in the context of romantic relationships. Previous research reported gender differences in ratings of jealousy over a sexual versus emotional infidelity. This study explored culture and gender differences in jealousy using a mixed methods survey design. One hundred and forty-five undergraduates from the University of Hawai‘i at Hilo participated. The Horizontal and Vertical Individualism and Collectivism Scale, Self-Report Jealousy Scale, and a modified Emotional and Sexual Jealousy Scale were used for analyses. Two hierarchical multiple regression analyses revealed that gender was a better predictor than culture in jealousy ratings involving an emotional infidelity; but culture was a better predictor for jealousy ratings involving a sexual infidelity. t-Tests also revealed that those who experienced an infidelity in the past reported significantly higher jealousy ratings and that women reported significantly higher jealousy ratings in emotional but not in sexual infidelity than men. The qualitative results revealed four dominant themes related to participant’s causal attributions of jealousy: Infidelity, Expectations of Time and Commitment, Social Media and Self-Esteem. The authors suggest that future research focus on intersexual and intrasexual differences in jealousy, as well the role social media may play in relationship expectations.     

Attachment-style differences in the experience and expression of romantic jealousy

According to attachment theory, the attachment system is activated to manage thoughts, feelings, and behaviors that stem from potential separation and relational threat. Thus, jealousy provides an important situation in which to examine attachment-style differences. In the present study, 144 individuals currently involved in enduring romantic relationships completed questionnaires regarding their jealousy experience, jealousy expression, and attachment styles. Four major findings emerged. First, those with negative self-models reported experiencing more cognitive jealousy than did those with positive self-models Second, jealous individuals with negative other-models reported feeling fear less intensely, using less relationship-maintaining behavior, and engaging in more avoidance/denial than did those with positive other-models. Third, preoccupieds reported displaying more negative affect and engaging in more surveillance behavior than did those with other attachment styles. Finally, dismissives reported feeling less fear than did secures and preoccupieds, and less sadness than preoccupieds, when experiencing jealousy. Attachment-style dimensions, such as lack of confidence and preoccupation with relationships, were also associated with jealousy experience and expression. These results are interpreted in light of attachment-theory principles.     

Sexual jealousy: Gender differences in response to partner and rival

Young women (N = 64) and men (N = 52) were asked to imagine discovering that their romantic partner had been sexually unfaithful. Fewer men than women gave positive endorsements to sets of aggressive actions against the unfaithful partner and against the rival. Gender differences did not appear in the motive for taking action against the rival, but more men than women endorsed releasing frustration as the motive for aggressive action against the partner. The genders appeared equally interested in maintaining the relationship with the unfaithful partner, preventing future infidelity, and attracting another partner. More men than women said they were uncertain about their partner's sexual fidelity. The results were interpreted as evidence that women are devalued more than men by an act of sexual infidelity, resulting in men's greater frustration with the partner's transgression but relative behavioral indifference to both the transgressing partner and rival. Men's greater uncertainty about a partner's infidelity may provide the basis for, as suggested by other data, men's greater tendency to ensure that a partner's infidelity and consequent devaluation never occur. © 1994 Wiley-Liss, Inc.     

Individual differences in romantic jealousy: The moderating effect of relationship characteristics

Previous research suggests that people who experience romantic jealousy in their relationships are typically low in self-esteem and high in neuroticism. The purpose of this paper is to examine whether the effects of personality are moderated by the nature of the relationships. Data based on 101 respondents suggest that the jealousy–personality correlations are more apparent among dating couples with less established relationships.     

Marital status as a candidate moderator variable of male-female differences in sexual jealousy: the need for representative population samples

Evolutionary psychological theories predict pronounced and universal male-female differences in sexual jealousy. Recent cross-cultural research, using the forced-choice jealousy items pioneered by Buss, et al., 1992, repeatedly found a large sex differential on these self-report measures: men significantly more often than women choose their mate's imagined sexual infidelity to be more distressing or upsetting to them than an imagined emotional infidelity. However, this body of evidence is solely based on undergraduate samples and does not take into account demographic factors. This study examined male-female differences in sexual jealousy in a community sample (N = 335, Eastern Austria). Within a logistic regression model, with other variables controlled for, marital status was a stronger predictor for sexual jealousy than respondents' sex. Contrary to previous research, the sex differential's effect size was only modest. These findings stress the pitfalls of prematurely generalizing evidence from undergraduate samples to the general population and the need for representative population samples in this research area.     

A reproductive threat-based model of evolved sex differences in jealousy

Although heterosexual women and men consistently demonstrate sex differences in jealousy, these differences disappear among lesbians and gay men as well as among heterosexual women and men contemplating same-sex infidelities (infidelities in which the partner and rival are the same sex). Synthesizing these past findings, the present paper offers a reproductive threat-based model of evolved sex differences in jealousy that predicts that the sexes will differ only when the jealous perceivers' reproductive outcomes are differentially at risk. This model is supported by data from a web-based study in which lesbians, gay men, bisexual women and men, and heterosexual women and men responded to a hypothetical infidelity scenario with the sex of the rival randomly determined. After reading the scenario, participants indicated which type of infidelity (sexual versus emotional) would cause greater distress. Consistent with predictions, heterosexual women and men showed a sex difference when contemplating opposite-sex infidelities but not when contemplating same-sex infidelities, whereas lesbians and gay men showed no sex difference regardless of whether the infidelity was opposite-sex or same-sex.     

Sex differences in brain activity, personality and intelligence: a test of arousability theory

This report describes empirical tests of the theory that females have higher levels of behavioural and cerebral arousal than males and that these differences cause higher neuroticism scores in females, as well as lower female psychoticism scores and lower scores for females on the Gsar factor of intelligence. Data were obtained from 76 subjects, with equal numbers of males and females and with all adult ages represented. EEG responses to auditory stimulation were quantified in terms of the ‘amplitude, ‘rate of change of amplitude and ‘sweep variability factors obtained from a principal components analysis (PCA). Gf, Gc and Gsar intelligence scores were obtained from a PCA of sub-tests from the Wechsler Adult Intelligence Scale plus Ravens Advanced Progressive Matrices test. Personality differences were evaluated using the Neuroticism and Psychoticism scales of the Eysenck Personality Questionnaire (EPQ). Bivariate hypotheses relating sex to the arousal, intelligence and personality variables were confirmed. A PCA demonstrated that sex, neuroticism, Gsar, wakefulness and high frequency EEG activity all have high loadings on a common factor. These results are consistent with expectations generated by the cerebral arousability theory of personality and intelligence.     

Sex differences in interaction style as a product of perceived sex differences in competence

Males' and females' interaction styles were observed while they worked in four-person, mixed-sex groups on a discussion task. In some groups, members were only given information about each others' names and gender. In this circumstance, men were perceived by themselves and other group members to be higher in competence than women. Further, men engaged in a greater amount of active task behavior than women (e.g., giving information, giving opinions), and women exhibited a greater amount of positive social behavior than men (e.g., agreeing, acting friendly). In other groups, members' competency-based status was manipulated by providing false feedback that they were high or low relative to their group in intellectual and moral aptitude. High status members were then perceived to be more competent than low status ones and, further, high status individuals engaged in more active task and less positive social behavior than low status ones. In this condition, no sex differences were obtained on perceived competence or on active task or positive social behavior. Overall, these findings support the idea that the gender differences obtained in interaction when status was not specified were partially a function of group members' belief that the sexes differ in competence. Direct information concerning members' intellectual and moral competence apparently blocked the perceived gender-to-competence link, and status alone affected perceived competence and interaction style.     

Sex differences in affective responses as evidenced on the Bene-Anthony Test

This study investigates changes in a child's perception of the relationship with male and female parents during the course of the critical ages of 5, 6, 7, and 8. Correspondingly, since the paper concerns itself with nonpathological normal children, it also provides normative data on the Bene-Anthony Family Relations Test. Findings indicate variable gender and age differences in the feelings experienced by children aged 5, 6, 7, and 8 towards male and female parents. There are differences between male and female children in their attitudes toward mother and father, and there are significant changes within the age ranks. Sweeping norms which do not take age and gender into account are inappropriate on the basis of our findings.     

Measuring romantic jealousy: Validation of the multidimensional jealousy scale in Australian samples

Although a number of questionnaires have been developed to measure romantic jealousy, there is a lack of independent research that has substantiated their psychometric properties and minimal research that has tested and applied these measures in a consistent and reliable way. We aimed to address these gaps by providing the first validation study of an existing measure of romantic jealousy—the Multidimensional Jealousy Scale (MJS). The MJS was subjected to exploratory and confirmatory factor analyses in two separate samples of individuals in romantic relationships of at least 2 months duration. A 17‐item Short‐Form MJS (SF‐MJS) was supported, with three factors representing cognitive, emotional, and behavioural jealousy. Internal reliabilities were high. Consistent evidence supported the discriminant and concurrent validity of the SF‐MJS. Overall, the current research provides a brief, validated measure of romantic jealousy for use in the general population. Potential clinical uses are discussed.
