Perceived risk of female infidelity moderates the relationship between men’s personality and partner-directed violence

We hypothesized that men’s personality traits interact with men’s perceived risk of partner’s infidelity to predict men’s partner-directed violence. Moderation analyses of data provided by 467 men in a committed relationship indicated that: (1) men with lower emotional stability, agreeableness, and conscientiousness, and men who perceived greater risk of partner infidelity perpetrated more partner-directed violence, and (2) the relationship between men’s personality traits and partner-directed violence depends on their perceptions of the risk of partner infidelity. Simple slope analyses indicated that: (a) men’s emotional stability and agreeableness predict partner-directed violence only when perceived risk of partner infidelity is low, and (b) men’s conscientiousness predicts partner-directed violence only when perceived risk of partner infidelity is high.     

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.     

Women’s oral sex behaviors and risk of partner infidelity

Pham and Shackelford (2013a) documented that men at greater risk of their partner’s infidelity reported greater interest in and spent more time performing oral sex on their partner. The current study is an extension of their study to a female sample. We recruited 200 women to investigate whether women’s oral sex behaviors are related to the risk of their partner’s infidelity. The results indicate that women at greater risk of partner infidelity did not report more interest in, or spend more time performing, oral sex on their partner. Additionally, the relationships between partner infidelity risk and interest in, and time spent, performing oral sex were greater for men than women. We discuss limitations of this research and discuss explanations for the results.     

Understanding Infidelity: How Perceptions of Infidelity Behaviors Vary by Sex and One's Own Infidelity Experiences

This study examines (1) how previous history with infidelity influences perceptions of cheating behaviors, and (2) sex's impact on ratings of cheating behaviors. A total of 83 undergraduate students enrolled in psychology courses volunteered to participate through an anonymous online survey. Participants rated sexual and emotional behaviors on a scale that ranged from “always” to “never,” indicating if the behavior was perceived as cheating. Individuals that had previous experience with infidelity either as the involved or non-involved partner rated sexual behaviors higher than those with no experience with infidelity, while non-involved partners rated emotional behaviors higher than the rest. Overall, females rated sexual and emotional behaviors higher than males. Non-involved males rated sexual behaviors higher than non-involved female partners. However, males who have not committed an infidelity rated sexual behaviors lower than any other group. The results provide further evidence that perceptions of cheating behaviors are influenced by gender and one's own history of infidelity, including both involved and non-involved roles.     

Effect of Cheating Experience on Attitudes toward Infidelity

The present study investigated how cheating experience influences perception of others’ infidelity. Using vignette characters, we explored the hypothesis that a participant’s experience cheating on a partner and gender of vignette character moderate gender-differentiated perceptions of infidelity (i.e., men reporting more accepting attitudes toward infidelity than women). Participants (N = 320) were asked a series of questions evaluating both how ‘acceptable’ and ‘forgivable’ was a vignette character’s infidelity. Men and women with prior experience cheating found the cheating vignette character of their same gender significantly more acceptable and forgivable than the unfaithful character of the other gender. Participants who reported no history of infidelity found infidelity as generally unacceptable, regardless of character gender.     

Oral sex as infidelity-detection

An evolutionary history of human female infidelity and consequent sperm competition may have caused the evolution of male counter-adaptations. The infidelity-detection hypothesis for oral sex proposes that men perform oral sex to gather information about their partner’s recent sexual history. We tested this hypothesis with data secured from 231 men in committed, sexual, heterosexual relationships. We found support for two derivative predictions: men at a greater recurrent risk of sperm competition expressed greater interest in, and spent more time performing, oral sex on their partner, even after controlling statistically for relationship length, relationship satisfaction, and sexual intercourse duration. The discussion addresses limitations of this research and highlights directions for future research, including distinguishing empirically the infidelity-detection hypothesis from alternative hypotheses for oral sex.     

Exploitative male mating strategies: Personality, mating orientation, and relationship status

Previous research suggests men are sexually attracted to women displaying cues to sexual exploitability. During human evolutionary history, men’s agreeableness, orientation towards casual sex, and relationship status may have been recurrently associated with greater net benefits of pursuing a sexually exploitative strategy. We hypothesized these three individual differences would predict men’s perceptions of women’s sexual exploitability. Seventy-two men viewed photographs of women and rated their sexual exploitability. Men’s agreeableness, sociosexual orientation, and current relationship status interacted to predict their perceptions of women’s sexual exploitability; among unmated men, the combination of low agreeableness and an orientation toward uncommitted sex was associated with higher perceptions of women’s sexual exploitability. This suggests mechanisms motivating sexually exploitative strategies may depend on an interaction between personality characteristics and situational variables.     

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.     

Gender differences in rival characteristics that evoke jealousy in response to emotional versus sexual infidelity

Previous research has shown that in men jealousy is evoked more by a rival's status‐related characteristics than in women, whereas in women jealousy is evoked more by a rival's physical attractiveness than in men. The present study examined whether the occurrence of this gender difference depends upon the type of infidelity one's partner engages in, i.e., emotional or sexual infidelity, and whether these types of jealousy evoke different emotional responses. An experiment was conducted using hypothetical jealousy situations with a 2 (participant gender: male vs. female) × 2 (rival physical attractiveness: high vs. low) × 2 (rival dominance: high vs. low) × 2 (type of infidelity: sexual vs. emotional) mixed‐factor design. Jealousy evoked by emotional infidelity was primarily characterized by feelings of threat, and jealousy after sexual infidelity was primarily characterized by feelings of betrayal and anger. Following emotional infidelity, in men, a rival's dominance, and in women, a rival's physical attractiveness, evoked feelings of threat but not feelings of anger‐betrayal. In contrast, after sexual infidelity, in men, but not in women, a rival's physical attractiveness evoked feelings of betrayal‐anger but not anxiety or suspicion.     

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.     

Perceived association between diagnostic and non-diagnostic cues of women’s sexual interest: General Recognition Theory predictors of risk for sexual coercion

Young men’s errors in sexual perception have been linked to sexual coercion. The current investigation sought to explicate the perceptual and decisional sources of these social perception errors, as well as their link to risk for sexual violence. General Recognition Theory (GRT; [Ashby, F. G., & Townsend, J. T. (1986). Varieties of perceptual independence. Psychological Review, 93, 154-179]) was used to estimate participants’ ability to discriminate between affective cues and clothing style cues and to measure illusory correlations between men’s perception of women’s clothing style and sexual interest. High-risk men were less sensitive to the distinction between women’s friendly and sexual interest cues relative to other men. In addition, they were more likely to perceive an illusory correlation between women’s diagnostic sexual interest cues (e.g., facial affect) and non-diagnostic cues (e.g., provocative clothing), which increases the probability that high-risk men will misperceive friendly women as intending to communicate sexual interest. The results provide information about the degree of risk conferred by individual differences in perceptual processing of women’s interest cues, and also illustrate how translational scientists might adapt GRT to examine research questions about individual differences in social perception.     

Understanding Variations in Judgments of Infidelity: An Application of Attribution Theory

The current program of research examined how the four dimensions of the attribution (locus of causality, controllability, stability, intentionality) influenced judgments of a partner’s hypothetical infidelity and actor-observer discrepancies associated with judgments of real-life infidelity. The results from Study 1 (N?=?396) revealed that the dimensions of the attribution affected the extent to which adults’ judged a partner’s hypothetical behavior as indicative of infidelity differently depending on the type of behavior. When reporting on real-life behavior (Study 2, N?=?802), adults attributed the cause of their partner’s infidelity as being a result of internal, controllable, stable, and intentional causes to a greater extent than when judging their own infidelity.     

Gender differences in subjective distress to emotional and sexual infidelity: Evolutionary or logical inference explanation?

Men and women were asked to imagine a romantic partner being sexually unfaithful and/or emotionally unfaithful. Three hypotheses regarding gender differences in subjective distress to sexual and emotional infidelity, and in the inferences linking the infidelities were tested. The results indicated that more men than women were distressed by imagining a partner enjoying passionate sexual intercourse with another person, and more women than men were distressed by imagining a partner forming a deep emotional attachment to another person. Asking another group of women and men to imagine a partner committing both infidelities at the same time, and then to indicate which component of the combined infidelity was the most distressing, produced the same sexual asymmetries. The prediction that men will infer from a partner's sexual infidelity the co-occurrence of emotional infidelity and that women will infer from a partner’s emotional infidelity the co-occurrence of sexual infidelity was not supported. An evolutionary perspective, rather than an alternative analysis emphasizing the different inferences men and women draw from sex and love, provided a satisfactory explanation of the sexual asymmetries in the cues to jealousy.     

Forgiveness or breakup: Sex differences in responses to a partner's infidelity

Infidelities--sexual, emotional, or both--afflict many long-term romantic relationships. When a person discovers a partner's betrayal, a major decision faced is to forgive the partner and remain together or to terminate the relationship. Because men and women have confronted different adaptive problems over evolutionary history associated with different forms of infidelity, we hypothesised the existence of sex differences in which aspects of infidelity would affect the likelihood of forgiveness or breakup. We tested this hypothesis using forced-choice dilemmas in which participants (N = 256) indicated how difficult it would be to forgive the partner and how likely they would be to break up with the partner, depending on the nature of the infidelity. Results support the hypothesis that men, relative to women: (a) find it more difficult to forgive a sexual infidelity than an emotional infidelity; and (b) are more likely to terminate a current relationship following a partner's sexual infidelity than an emotional infidelity. The Discussion provides directions for future work on the determinants of breakup and the psychology of forgiveness.     

Female aggression as a response to sexual jealousy: A sex role reversal?

Sexual jealousy can be interpreted as a strategy which serves to retain the partner and defend exclusive sexual relationships. Because of the asymmetry in paternity confidence, it should be a more important strategy for males than for females. Indeed, male sexual jealousy is apparently a cross-cultural phenomenon and is often the proximate cause of violence against the female partner. The objective of this study was to investigate through self-report whether male “victims” of partner infidelity are expected to react more aggressively than female “victims,” how subjects themselves say they would react to a partner's infidelity, and whether these expectations vary across the sexes. Contrary to our predictions, subjects expected females more than males to react aggressively and revengefully when confronted with infidelity. These expectations were mainly sustained by the female subjects. Females were also more likely than males to declare that they themselves would verbally and physically abuse the partner. In addition, female subjects anticipated that they would cry, feign indifference, and try to look attractive and cool. Males were more likely than females to report that they would get drunk. Our results on aggressive reactions represent a departure from traditional sex roles. It is argued that emancipatorial development, as well as the levelling influence of contraceptives on the sexes' parental certainty, have triggered this change in sex roles. © 1993 Wiley-Liss, Inc.

Women’s perception of men’s sensation seeking propensity from their dance movements

Risk-taking behaviour in men, an expression of the more general personality trait sensation seeking, has been hypothesized to be an evolved aspect of male psychology that arose through sexual selection. Sensation seeking could be seen as a costly behavioural trait that signals a man’s health and vigour and is preferred by women. This study extends knowledge about risk-taking as a cue in human mate choice by examining whether women can perceive men’s sensation seeking propensity (assessed with the Sensation Seeking Scale Form V; SSS-V) by viewing their dance movements. We videotaped 50 men’s dancing and had 60 women judge each dancer on perceived attractiveness and risk-taking. A positive and significant correlation was found between women’s attractiveness judgements and male’s SSS-V total score, thrill and adventure seeking, disinhibition and boredom susceptibility. Further, women’s risk-taking judgements were related to men’s boredom susceptibility. We conclude that (i) male sensation seeking propensity is signalled via their dance movements, and (ii) women are sensitive to these cues as they consider men who score high on sensation seeking as attractive. We discuss our results with reference to the evolutionary psychology concept of sexual selection and mate preferences.     

Mate-preference drives mate-choice: Men’s self-rated masculinity predicts their female partner’s preference for masculinity

Women who rate their male partner as more masculine tend to prefer more masculine faces. However, it is unclear whether a preference for masculinity causes women to select masculine partners, or to perceive their current partner as more masculine. By incorporating multiple measures of male masculinity, we establish that women’s preference for facial masculinity in short-term partners is correlated with their rating of their partner’s masculinity and with their partner’s self-rated masculinity, but with neither independent ratings of men’s facial masculinity nor a facialmetric masculinity index. Facial masculinity preference in long-term partners is correlated with women’s rating of partner masculinity, with a similar trend for men’s self-rating. Multiple regression analyses demonstrated that these relationships were independent of age, although only for short-term preference. We conclude that women who prefer masculine men tend to have more masculine partners, and therefore that mate-preferences do drive mate-choice.     

Sexual willingness with same- and other-sex prospective partners: Experimental evidence from the bar scene

Sex is ubiquitous in the media, but only a fraction depicts sexual interactions between same-sex partners. This field study, conducted outside of bars in the Midwestern United States, examined 83 heterosexuals’ sexual willingness with a same- or other-sex partner. Participants viewed a randomly assigned video vignette of a same- or other-sex partner. Alcohol intake, partner attractiveness, and sexual willingness were measured. Using moderated regression analysis, we found that alcohol intake predicted sexual willingness with the male target for both men and women, but not with the female target. The attractiveness of same-sex partners was related to sexual willingness. Sexual willingness was only influenced by alcohol intake and perceived attractiveness of a same-sex prospective partner. Most notably, alcohol intake was related to increased sexual willingness of men with a same-sex partner, suggesting a potential shift in normative casual sexual behavior among heterosexual men.     

Men’s personality and women’s perception of their dance quality

Recent research shows that women judge men who show variability in their body movements as good dancers. Here we report data on women’s perception of dance quality in 48 men, aged 18-42 years, and relate them to men’s self-reported personality traits. Male participants completed a standardised personality inventory (the NEO-FFI) and then danced to a basic rhythm while their body movements were tracked with optical 3D motion-capture technology. Dance movements were applied to a featureless virtual humanoid character and judged on their dance quality by 53 women, aged 17-57 years, who viewed 15 s of the rendered video clips of each male dancer. Conscientiousness and social agreeableness was correlated positively and significantly with women’s perception of men’s dance quality. Extraversion showed a positive correlation and neuroticism and openness were associated negatively with women’s perception of men’s dance quality, though these correlations failed to reach significance. We suggest that male dance movements may convey aspects of their personality, though possible consequences in terms of female mate preferences and selection remain to be explored.
