Prioritization of Potential Mates' History of Sexual Fidelity During a Conjoint Ranking Task

Ideological Mate-guarding: Sexual Jealousy and Mating Strategy Predict Support for Female Honor

Feminine honor dictates that women should cultivate a reputation for sexual purity via behaviors such as dressing modestly and maintaining virginity before marriage. The dominant explanation for people's support for feminine honor is that female infidelity threatens male partners' honor. Beyond this, the literature affords little understanding of the evolutionary and psychological origins of feminine honor. We propose that feminine honor functions as an ideological form of mate guarding that is shaped by sexual jealousy and mating strategy. Two correlational studies (N  =  892) revealed support for predictions derived from this ideological mate-guarding account. In Study 1, dispositional jealousy and mating strategy (more monogamous orientation) predicted male participants' support for a mate's (especially a long-term mate's) feminine honor. Moving beyond mate preferences, in Study 2 male and female participants' dispositional jealousy and mating strategy predicted support for feminine honor of women in general. Results applied beyond masculine honor norms, religiosity, political conservativism, and age. These findings enhance the understanding of the origins and maintenance of feminine honor and related norms and ideologies that enable control over women's socio-sexual behavior.

Mate-value and relationship satisfaction: The moderating roles of mate retention behaviors

Previous research indicates that mate retention strategies are associated with mate value and affect relationship satisfaction. The current research aimed to replicate previous findings in a non-WEIRD society (Iran) and to extend this research by investigating the moderating roles of individual and coalitional mate retention. Participants (n = 754; 416 women) in a committed, heterosexual relationship from two independent samples reported (1) their relationship satisfaction, (2) their partner's mate value, (3) the frequency of performing individual mate retention, and (4) the frequency of requesting coalitional mate retention. Results indicated that there were positive associations between mate value, individual and coalitional Benefit-Provisioning mate retention behaviors, and relationship satisfaction. We found negative associations between individual and coalitional Cost-Inflicting mate retention behaviors and relationship satisfaction. We found that mate retention moderated the relationship between mate value and relationship satisfaction. Limitations of the current study are noted, and future directions are discussed.

Testing the Mate Preference Priority Model with the Profile-Based Experimental Paradigm: A Replication and Extension

OBJECTIVE

Although the mate preference priority model (MPPM; Li et al., 2002) has advanced our understanding of mate preferences, tests of the MPPM have relied on methods using text labels and thus lack ecological validity. We address this gap by testing the MPPM using Townsend and colleagues' (1990a; 1990b; 1993) profile-based experimental paradigm, which utilizes profiles comprising photos of pre-rated models to manipulate physical attractiveness as well as costumes and descriptions to manipulate social status.

METHOD

Using Singaporean samples, we conducted two studies (Study 1 n = 431, Study 2 n = 964) where participants judged the short-term and long-term mating desirability of opposite-sex profiles varying systematically on physical attractiveness and social status. We also tested whether treating these attributes as ordinal or continuous variables would be more valid.

RESULTS

Results showed broad support for evolutionary predictions of mate preferences and priorities while revealing an increased premium placed on social status in our sample. We also found that continuous operationalizations produced less inflated results.

CONCLUSIONS

The current research provides the first non-label, profile-based test of the MPPM, a well-powered replication of the profile-based paradigm, and an opportunity to observe the robustness and variations of mate preferences in a non-Western culture.

E-perceptions and Business 'Mating': The Communication Effects of the Relative Width of Males' Faces in Business Portraits

This study investigates the relative impacts of the facial width-to-height ratio (fWHR) on the first impressions business professionals form of business consultants when seeing their photographs on a corporate website or LinkedIn page. By applying conjoint analysis on field experiment data (n = 381), we find that in a zero-acquaintance situation business professionals prefer low-fWHR business consultants. This implies that they prefer a face that communicates trustworthiness to one that communicates success. Further, we have investigated the words that business professionals use to describe their preferred consultant. These approach motivations help practitioners to improve the picture-text alignment. The results underline the necessity to critically assess the pictures and text used on websites and media platforms such as LinkedIn for business purposes, and to see them as a key element of business and self-communication that can be altered in order to improve business 'mating.'

Voice Pitch – A Valid Indicator of One’s Unfaithfulness in Committed Relationships?

Objectives

When judging a male speakers’ likelihood to act sexually unfaithful in a committed relationship, listeners rely on the speakers’ voice pitch such that lower voice pitch is perceived as indicating being more unfaithful. In line with this finding, a recent study (Schild et al. Behavioral Ecology, 2020) provided first evidence that voice pitch might indeed be a valid cue to sexual infidelity in men. In this study, male speakers with lower voice pitch, as indicated by lower mean fundamental frequency (mean F0), were actually more likely to report having been sexually unfaithful in the past. Although these results fit the literature on vocal perceptions in contexts of sexual selection, the study was, as stated by the authors, underpowered. Further, the study solely focused on male speakers, which leaves it open whether these findings are also transferable to female speakers.

Methods

We reanalyzed three datasets (Asendorpf et al. European Journal of Personality, 25, 16–30, 2011; Penke and Asendorpf Journal of Personality and Social Psychology, 95, 1113–1135, 2008; Stern et al. 2020) that include voice recordings and infidelity data of overall 865 individuals (63,36% female) in order to test the replicability of and further extend past research.

Results

A significant negative link between mean F0 and self-reported infidelity was found in only one out of two datasets for men and only one out of three datasets for women. Two meta-analyses (accounting for the sample sizes and including data of Schild et al. 2020), however, suggest that lower mean F0 might be a valid indicator of higher probability of self-reported infidelity in both men and women.

Conclusions

In line with prior research, higher masculinity, as indicated by lower mean F0, seems to be linked to self-reported infidelity in both men and women. However, given methodological shortcomings, future studies should set out to further delve into these findings.

Jealousy, Consent, and Compersion Within Monogamous and Consensually Non-Monogamous Romantic Relationships

Evolutionary psychological research has studied romantic jealousy extensively within monogamous relationships, but has largely ignored jealousy among partners who mutually consent to forming extra-pair relationships (i.e., consensual non-monogamy; CNM). We examined monogamous (n = 529) and CNM (n = 159) individuals' reactions to imagining their romantic partner(s)'s extra-pair involvement. For each romantic partner, men and women completed measures of relationship jealousy and reacted to scenarios of their partner's extra-pair emotional and sexual involvement. Scenarios prompted participants to indicate which type of involvement would be more distressing and more enjoyable. They also described whether or not participants had consented to their partner's extradyadic relationship. Monogamous men were more distressed by a partner's extradyadic sexual versus emotional involvement (and a partner's emotional involvement was more enjoyable) whether the scenario was consensual or not. Monogamous women were more distressed by a partner's emotional versus sexual involvement (and a partner's sexual involvement was more enjoyable) for consensual, but not non-consensual, scenarios. There were no gender differences among CNM participants. Monogamous individuals reported greater emotional distress toward a partner's imagined extradyadic involvement, whereas CNM individuals reported thinking about their partner's extra-pair relationships more frequently. Monogamous (vs. CNM) individuals reported greater confidence that their partner would never cheat on them (i.e., enter another relationship without their consent), and CNM participants were more confident that their primary versus secondary partner would never cheat, although this effect was stronger among CNM women. Moreover, CNM participants rated that it was more important that their primary versus secondary partner did not cheat, and reported greater distress imagining that their primary versus secondary partner had cheated. Women in CNM relationships rated it more important that their partner did not cheat sexually than emotionally. Finally, we replicated previous research showing that monogamous individuals mate guard more than CNM individuals, who mate guard their primary versus secondary partner more frequently. Future directions for developing evolutionary and romantic relationship research on CNM are discussed.

The Relative Contribution of Jawbone and Cheekbone Prominence, Eyebrow Thickness, Eye Size, and Face Length to Evaluations of Facial Masculinity and Attractiveness: A Conjoint Data-Driven Approach

Recent work demonstrates the methodological rigor of a type of data-driven analysis (i.e., conjoint analysis; CA), which accounts for the relative contribution of different facial morphological cues to interpersonal perceptions of romantic partner quality. This study extends this literature by using a conjoint face ranking task to predict the relative contribution of five sexually dimorphic facial shape features (jawbone and cheekbone prominence, eyebrow thickness, eye size, face length) to participants’ (N = 922) perceptions of facial attractiveness and sex-typicality (i.e., masculinity/femininity). For overall partner attractiveness, eyebrow thickness and jawbone prominence were relatively more salient than cheekbone prominence and eye size. Interestingly, masculinized (i.e., thicker) eyebrows were marginally more attractive for female than male faces, particularly within a long-term mating context. Masculinized jawbone prominence was more attractive for male than female faces, and feminized jawbone prominence was more attractive for female than male faces. For perceptions of masculinity, eyebrow thickness, jawbone prominence, and facial height were relatively more salient than cheekbone prominence and eye size, although facial height was more important for female than male faces, and jawbone prominence was marginally more important for male than female faces. These findings highlight the prominence of eyebrows, the jawline, and facial height during perception of facial attractiveness and masculinity – though it should be noted that many of these differences were small to moderate in effect size. Findings are interpreted in the context of prior research, and future directions for studying why these facial traits exhibit superior signaling capacity are discussed.

Emotional Accessibility Is More Important Than Sexual Accessibility in Evaluating Romantic Relationships - Especially for Women: A Conjoint Analysis

Prior research examining mate expulsion indicates that women are more likely to expel a mate due to deficits in emotional access while men are more likely to expel a mate due to deficits in sexual access. Prior research highlights the importance of accounting for measurement limitations (e.g., the use of incremental vs. forced-choice measures) when assessing attitudes toward sexual and emotional infidelity, Sagarin et al., 2012, Wade and Brown, 2012). The present research uses conjoint analysis, a novel methodology for controlling several limitations of using continuous self-report measures in mate expulsion research. Participants (N = 181, 128 women) recruited from Bucknell University and several psychology recruitment listservs in the United States rated nine profiles that varied in three potential levels of emotional and sexual accessibility. Men were more likely to want to break up with a partner due to sexual accessibility deficits, whereas women were more likely to want to break up due to emotional accessibility deficits. However, regardless of sex, emotional inaccessibility was more likely to produce mate expulsion. These findings are consistent with prior theory and highlight the need to disentangle emotional accessibility into its constituent in-pair benefits. This research also illustrates the utility of conjoint analysis as a statistical tool for studying how humans resolve trade-offs among competing outcomes during romantic decision-making.

The Relative Importance of Sexual Dimorphism, Fluctuating Asymmetry, and Color Cues to Health during Evaluation of Potential Partners' Facial Photographs : A Conjoint Analysis Study

Sexual dimorphism, symmetry, and coloration in human faces putatively signal information relevant to mate selection and reproduction. Although the independent contributions of these characteristics to judgments of attractiveness are well established, relatively few studies have examined whether individuals prioritize certain features over others. Here, participants (N = 542, 315 female) ranked six sets of facial photographs (3 male, 3 female) by their preference for starting long- and short-term romantic relationships with each person depicted. Composite-based digital transformations were applied such that each image set contained 11 different versions of the same identity. Each photograph in each image set had a unique combination of three traits: sexual dimorphism, symmetry, and color cues to health. Using conjoint analysis to evaluate participants' ranking decisions, we found that participants prioritized cues to sexual dimorphism over symmetry and color cues to health. Sexual dimorphism was also found to be relatively more important for the evaluation of male faces than for female faces, whereas symmetry and color cues to health were relatively more important for the evaluation of female faces than for male faces. Symmetry and color cues to health were more important for long-term versus short-term evaluations for female faces, but not male faces. Analyses of utility estimates reveal that our data are consistent with research showing that preferences for facial masculinity and femininity in male and female faces vary according to relationship context. These findings are interpreted in the context of previous work examining the influence of these facial attributes on romantic partner perception.

Monogamy versus Consensual Non-Monogamy: Alternative Approaches to Pursuing a Strategically Pluralistic Mating Strategy

This study examined the frequency of partner-directed mate retention behaviors and several self- and partner-rated romantic relationship evaluations (i.e., sociosexuality, relationship satisfaction, mate value, and partner ideal measures) within monogamous and consensually non-monogamous (CNM) relationships. Measures were compared (1) between monogamous and CNM participants and (2) between two concurrent partners within each CNM relationship (i.e., primary and secondary partners). We found that individuals in currently monogamous relationships (n = 123) performed more mate retention behaviors compared to those currently in CNM relationships (n = 76). Within CNM relationships, participants reported engaging in more mate retention behaviors with primary partners compared to secondary partners. Likewise, CNM participants reported talking about their extra-dyadic sexual experiences and downplaying these sexual experiences more often with their primary partner compared to their secondary partner. There were no significant differences between ratings of monogamous and primary partners in participants' overall relationship satisfaction. However, monogamous participants reported less satisfaction with the amount of communication and openness they had with their partner compared to CNM participants' reports of their primary partner, but not secondary partner. By comparison, CNM participants reported higher overall relationship satisfaction with primary compared to secondary partners and considered their primary partner to be more desirable as a long-term mate than their secondary partner. We interpret these results within the context of previous research on monogamous and CNM relationships and hypothesize that these relationship configurations are alternative strategies for pursuing a strategically pluralistic mating strategy.

Mate Value Discrepancy and Mate Retention Behaviors of Self and Partner

OBJECTIVE

This study investigated the relationship between perceived mate value discrepancy (i.e., the difference between an individual's mate value and their partner's mate value) and perceived frequency of mate retention performed by an individual relative to his or her partner.

METHOD

In two studies, participants in long-term, exclusive, sexual, heterosexual relationships reported their own, and their partner's, mate value and mate retention. Samples included 899 community members (Study 1) and 941 students and community members (Study 2).

RESULTS

In Study 1, we documented that individuals with higher self-perceived short-term mate value, and who perceive their partner to have lower (vs. higher) short-term mate value, perform less frequent Benefit-Provisioning mate retention, controlling for the partner's Benefit-Provisioning mate retention. In Study 2, we documented that individuals who perceive that they could less easily replace their partner, and who perceive their partner could more (vs. less) easily replace them, perform more frequent mate retention (Benefit-Provisioning and Cost-Inflicting), controlling for the partner's mate retention.

CONCLUSION

These results highlight the importance of assessing perceived discrepancies in mate value (notably, regarding the replaceability of self and partner with another long-term mate) and perceived mate retention behaviors of self, relative to partner, between men and women in long-term relationships.

Female Mate Choice : A Comparison Between Accept-the-Best and Reject-the-Worst Strategies in Sequential Decision Making

Information about prospective mates is typically acquired in a sequential and cumulative fashion. The aim of this study was to examine whether a reject-the-worst strategy is more efficient than an accept-the-best strategy for women in response to serial information and to identify the point at which a woman will terminate her assessment of a prospective mate's attributes. A pilot survey was conducted to determine the chronological order in which attribute information typically becomes available during the early stages of a relationship. Using this order of presentation, attributes were presented to participants one at a time. After participants specified their minimum acceptable percentile level for each attribute, they were given numerical feedback about the extent to which the prospect exceeded or failed to meet their standard. Participants were randomly assigned to either the accept-the-best condition (accept a date or request more information) or the reject-the-worst condition (reject a date or request more information). Participants in the reject-the-worst condition requested more trait information before making a decision than those in the accept-the-best condition. This suggests that the costs of a false-negative error exceed those of a false-positive error and that in actively accepting a mate, women satisfice rather than optimize.
