The sexual overperception bias is associated with sociosexuality

As reproductive rates have the potential to be higher in men than women, it is more costly (from an evolutionary perspective) for men to miss a mating opportunity than women. This asymmetry in costs has been proposed to result in men being more sensitive to cues to sexual opportunity than women, and thus men are more likely than women to misperceive sexual interest from opposite sex others. To investigate this sexual misperception bias, smiling male and female faces were presented to participants who were asked to judge whether the face appeared friendly or flirtatious. Participants also completed a sociosexual orientation questionnaire in order to assess their current attitudes towards sexual relationships. In general, we found that males perceive female faces as flirtatious significantly more often than females. However, our results also suggested that people with high scores on the sociosexuality inventory (who rated themselves as more likely to engage in short-term, casual relationships), regardless of sex, had a tendency to perceive the faces of potential mates as more flirtatious, and that this variable explained more variance than sex alone. Our findings demonstrate that sociosexuality may mediate biases in perceiving the sexual intent of others.     

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.     

Correlates of African American Men’s Sexual Schemas

Sexual schemas are cognitive representations of oneself as a sexual being and aid in the processing of sexually relevant information. We examined the relationship between sociosexuality (attitudes about casual sex), masculine ideology (attitudes toward traditional men and male roles), and cultural centrality (strength of identity with racial group) as significant psychosocial and sociocultural predictors in shaping young, heterosexual African American men??s sexual schemas. A community sample (n?=?133) of men in a southeastern city of the United States completed quantitative self-report measures examining their attitudes and behavior related to casual sex, beliefs about masculinity, racial and cultural identity, and self-views of various sexual aspects of themselves. Results indicated that masculine ideology and cultural centrality were both positively related to men??s sexual schemas. Cultural centrality explained 12?% of the variance in level of sexual schema, and had the strongest correlation of the predictor variables with sexual schema (r?=?.36). The need for more attention to the bidirectional relationships between masculinity, racial/cultural identity, and sexual schemas in prevention, intervention, and public health efforts for African American men is discussed.     

Sociosexual Orientation and Sexual Behavior in Mexican Adults

Sociosexual orientation includes individual differences in sexual attitudes and behaviors, in relation to the extent in which an individual could be sexually active without affective bonds and commitment. Sociosexuality is related to sexual behavior and can speak to the differences between men and women in how they express their sexuality ( Simpson & Gangestad, 1991 ; Hebl & Casi, 1995 ; Ostovich & Sabini, 2004 ). This study explores sociosexual orientation and sexual behavior in Mexican adults, in order to identify differences in sociosexual orientation related to biological sex and relationship status. It also assesses the relationship between sociosexual orientation and sexual behavior and to predict sexual behavior from sociosexual orientation. The sample was composed of 209 Mexican adults between 19 and 61 years of age. Thirty‐seven percent were male, and 63% were female. Participants answered a standardized Spanish version of the Sociosexual Orientation Inventory ( Simpson & Gangestad, 1991 ) and a Sexual Behavior Inventory developed for the present project ( García Rodríguez, 2007 ). In general, there is great variability in the frequency of each of the sexual behaviors assessed and in the total number of sexual partners. Moreover, participants perceive themselves restricted in their sexual attitudes and behaviors. Men are more permissive and less restricted in attitudes and behaviors than women, and individuals who are dating informally have a higher behavioral sociosexual orientation than those who are living with their partner. Additionally, the higher sociosexuality, the more frequent sexual practices are and the higher the number of sexual partners. Finally, sociosexuality predicts the frequency of sexual practices and the number of lifetime sexual partners.     

Male Role Norm Endorsement and Sexism Predict Heterosexual College Men’s Attitudes Toward Casual Sex,Intoxicated Sexual Contact,and Casual Sex

This study examined whether gender roles, particularly male role beliefs and sexism, may underlie self-reported attitudes toward and participation in casual sex and intoxication prior to sexual contact in a sample of heterosexual undergraduate men from the United States. We utilized online survey methods to examine whether men’s (N?=?223 from a large mid-Atlantic University) endorsement of traditional masculinity (power and status, toughness, and anti-femininity) and sexist attitudes regarding women’s roles (hostile, benevolent) were related to engagement in casual sex (i.e., number of one-time-only sex partners), and whether masculinity was related to intoxicated sexual contact (i.e., propensity to consume alcohol prior to sexual contact). Structural Equation Modeling (SEM) revealed that, as expected, endorsement of the toughness male role norm was positively associated with favorable attitudes toward casual sex, and endorsement of benevolent sexism was negatively associated with favorable attitudes toward casual sex. Favorable attitudes toward casual sex, in turn, were positively associated with men’s reported number of casual sex partners, as partially mediated by intoxicated sexual contact. Further, toughness endorsement was positively associated with number of casual sex partners via its positive association with intoxicated sexual contact; whereas power and status demonstrated the opposite, negative pattern. We discuss the contribution of this research to the broader literature on gender roles and sexual behavior and the utility of the findings for interventions aimed at reducing men’s casual sex behavior and intoxication prior to sexual contact.     

How are sociosexuality, sex drive, and lifetime number of sexual partners related?

In two studies (ns = 277 and 221), the authors examined the relationships among sex drive, sociosexuality, lifetime number of sex partners, and gender identity. They found that sex drive is highly and positively correlated with sociosexual orientation, and that both sex drive and sociosexual orientation are positively correlated with lifetime number of sex partners. However, partial correlations revealed that sociosexual orientation is an independent predictor of lifetime number of sex partners, whereas sex drive is not. The authors were also able to replicate and extend Mikach and Bailey's (1999) finding that gender identity is related to women's lifetime number of sex partners. More masculine women had more sex partners and had a less restricted sociosexual orientation than did less masculine women; less masculine men had a higher sex drive than did more masculine men. The findings are discussed with regard to theory and research on sex drive and sociosexuality.     

Is aversion to incest psychologically privileged? When sex and sociosexuality do not predict sexual willingness

As human possess powerful incest-avoidance mechanisms (which likely evolved due to the high costs of inbreeding), reactions to incestuous sexual encounters may be psychologically distinct from reactions to non-incestuous (but still non-normative) sexual encounters. Accordingly, variables such as sex and sociosexuality that normally predict openness to sexual encounters in other situations (i.e., men and sociosexually unrestricted people tend to be more sexually willing) may not do so – or do so only weakly – in incestuous situations. In Study 1, sociosexuality predicted negative judgments of non-incestuous (but still normatively proscribed) sexual acts, but not judgments of incestuous sexual acts. In Study 2, sociosexuality predicted negative reactions to imagined sex with biologically unrelated (but still normatively unusual) partners, but not reactions to imagined sex with related partners (this effect was limited to women); also, men reacted less negatively than women to imagined sex with unrelated partners, but men and women reacted equally negatively to imagined sex with related partners (the latter effect was limited to sociosexually restricted men).     

Men's sociosexuality is sensitive to changes in mate availability

Correlational research has linked mate availability to human sexual behavior, whereby unrestricted sociosexuality seems to be most common under conditions of female abundance. In this study, 71 heterosexual men were randomly assigned to one of two mate availability priming conditions, mate scarcity or mate abundance, and subsequently completed measures of sociosexuality as well as infidelity intentions. Results indicated that men in the mate abundance condition reported stronger sociosexual attitudes and desires, and among those currently in relationships, stronger infidelity intentions. These findings were contrasted with those from a separate sample of 66 heterosexual undergraduate women. Mate scarcity had no effects on women's sociosexuality or infidelity intentions. Findings suggest that when mates are scarce, men will adopt a sociosexual orientation aimed at maintaining a single partner.     

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.     

Factors predicting the probability of initiating sexual intercourse by context and sex

Despite men initiating sex more than women there is considerable variance within the sexes. This study is the first to consider the impact of multiple predictors from the literature, and investigates how factors, such as relationship length, sociosexuality, and different aspects of self‐perceived mate value among others, independently and interactively predict initiation of sexual intercourse in both short‐term sexual and long‐term romantic mating contexts, testing predictions from Sexual strategies theory. For long‐term relationships, positive partner bond increased initiative to sexual intercourse for women. For men, self‐perceived independence increased probability of taking the initiative, while relationship attachment decreased probability. For short‐term relations, the desire component of the sociosexual orientation inventory increased probability of initiation for both sexes, while male initiative was increased by pleasure reasons for sex. The impact of individual predictors on initiating intercourse is influenced by being included in a multidimensional model, and relationship context affects the impact of the predictors.     

Do individual differences in sociosexuality represent genetic or environmentally contingent strategies? Evidence from the Australian twin registry

Although men are substantially more interested than women in casual sex, there is ample variation in this trait (sociosexuality) within both sexes. One theory hypothesizes that within-sex sociosexual variation results from genetic variation maintained by frequency-dependent selection. If so, sociosexuality should be substantially heritable. A competing theory is that children acquire their mating strategy after observing their parents' relationship. By this theory, sociosexuality should reveal a strong shared environmental component. The authors studied genetic and environmental influences on sociosexuality using a large, representative volunteer twin sample. Parental marital instability was modestly associated with sociosexuality, but this could have been due to either genetic or environmental factors. Consistent with genetic theory, familial resemblance appeared primarily due to additive genetic rather than shared environmental factors.     

Revisiting correlates of sociosexuality for men and women: The role of love relationships and psychological maladjustment

The purpose of this work was to examine the links between sociosexuality, and love relationships and psychological maladjustment. Although males and females vary in connection with the sociocultural orientations, the involvements of this variation may not be similar for both sexes. The sample included 475 participants, 42% women and 58% men. Ages ranged from 18 through 80 (M = 37.28, SD = 16.27). Measures assessed sociosexuality, love styles, love satisfaction, compassionate love, commitment, romantic loneliness, and negative affect. Men displayed a more unrestricted sociosexual orientation than women. We found both sex similarities and differences in the associations between sociosexuality and love relationships and psychological maladjustment. For both sexes a similar pattern of correlations was found regarding erotic love, love satisfaction, and commitment. It seems that unrestricted women experience more psychological maladjustment, evidenced by romantic loneliness and negative affect than men. The findings are discussed with reference to past research and some suggestions for further work are also noted.

Adult Attachment and Heterosexual College Women’s Hookup Behaviors: Mediating Effects of Sexual Motives

We investigated sexual motives as mediators of the relationships between adult attachment orientations and women’s casual sexual behavior. Female heterosexual undergraduates (N = 221) provided self-report data on multiple attachment orientations underlying attachment styles, sexual motives, and hookup behavior. Proximity-seeking (i.e., turning toward others to share experiences and in times of need) and self-reliance (i.e., preferring not to ask for help or to depend on others) were both associated with number of hookup partners. Sexual motives mediated some of these relationships. Intimacy motives explained how proximity-seeking positively related to hookup behavior, whereas enhancement motives explained how self-reliance negatively related to hookup behavior. These results suggest that attachment orientations associated with both secure and insecure attachment styles predict women’s casual sexual behavior through different sexual motives. These results also suggest that women’s casual sexual encounters do not necessarily reflect insecurity, dysfunction, psychopathology, or maladaptation. To promote healthy hookup behaviors among women, both emotional as well as sexual needs associated with different attachment orientations should be considered.

Premarital Sexual Attitudes and Behavior at a Religiously-Affiliated University: Two Decades of Change

Decades of increases in premarital sexual involvement of college students have been related to numerous variables, one of which is religiosity. This investigation sought to determine any change in the premarital sexual attitudes and behaviors of students enrolled at a private religiously-affiliated university over a two-decade period of time. Using anonymous questionnaires administered in social science classes in 1981, 1991, and 2000, a total sample of 1,545 never-married undergraduates, 791 women and 754 men, was obtained. Significant behavioral differences were found between time intervals for women and men in age at first intercourse, number of sex partners, and demographic and personal characteristics. Among women, significant attitude changes concerned acceptance of sexual intercourse with casual and serious dating partners. Religiosity and participation in sexual intercourse were inversely related for women and men.     

Sociosexuality and everyday social interaction

This study examined whether sociosexuality, a variable measuring unrestrictedness of sexual attitudes and behaviors, relates to the everyday social interactions of individuals. Sociosexuality was measured using Simpson and Gangestad's (1991a) Sociosexual Orientation Inventory (SOI). Seventy-one participants completed daily interaction records assessing various aspects of each interaction they had over a 7-day period. The number of interactions in which they engaged, as well as the number of partners with whom they interacted, were correlated with scores on the SOL In addition, a multilevel data analytic approach was used to examine whether sociosexuality related to perceived Closeness, Quality, Negativity, and Sexual Interest during these interactions. Results were somewhat mixed. Women higher in sociosexuality reported both more extensive social networks and greater numbers of interactions, particularly with men, than women lower in sociosexuality. A marginally significant trend indicated that individuals higher in sociosexuality reported that interactions with their romantic partners contained greater Negativity than individuals lower in sociosexuality. In addition, both men and women higher in sociosexuality reported that interactions with their best friends were of poorer quality.     

The Morning After: Gender Differences In Attributions About Alcohol-Related Sexual Encounters1

Traditional sex role characteristics suggest that women may be more dissatisfied with casual sex than men. We investigated this notion by examining the reactions of women and men to a hypothetical, first-time sexual encounter. An additional factor that was hypothesized to affect reactions was the presence of alcohol, which may serve as a cue for sexual disinhibition. College students read a scenario depicting a consensual sexual encounter between two people who met at a party, and made judgments about the partners' behavior and characteristics. Four versions of the scenario varied the alcohol consumption of both characters. Results showed that men were more likely than women to find the behavior of each partner socially acceptable, to foresee a positive future for the couple as a result of their sexual encounter, and to predict that they themselves would engage in similar behavior. Although no main effects for alcohol consumption were found, alcohol consumption interacted with gender to influence judgments about the characters' sexuality. Results are discussed in terms of sex role stereotyping and the tendency of both sexes to misunderstand or misperceive each other's sexual feelings.     

Is high sex drive associated with increased sexual attraction to both sexes? It depends on whether you are male or female

If sex drive is a generalized energizer of sexual behaviors, then high sex drive should increase an individual's sexual attraction to both men and women. If sex drive energizes only dominant sexual responses, however, then high sex drive should selectively increase attraction to men or to women, but not to both, depending on the individual's sexual orientation. Data from three studies assessing a total of 3,645 participants show that for most women, high sex drive is associated with increased sexual attraction to both men and women. For men, however, high sex drive is associated with increased sexual attraction to only one sex or the other, depending on the individual's sexual orientation. These results suggest that the correlates of sex drive and the organization of sexual orientation are different for women and men.
