Introduction: Human observers rapidly infer socially relevant traits from faces, yet these judgments can be altered by appearance modifications such as cosmetic enhancement. It remains unclear whether cosmetic enhancement produces similar effects across different dimensions of facial evaluation and whether these effects are interpreted consistently across cultural contexts. The present study examined how cosmetic enhancement influences facial social evaluation among Chinese and British perceivers. Methods: In a preregistered mixed-design experiment, 100 Chinese participants and 99 British participants evaluated East Asian and Caucasian female faces presented in natural, light-makeup, or heavy-makeup conditions. Participants rated each face on attractiveness, dominance, competence, youthfulness, and trustworthiness. Results: Cosmetic enhancement increased perceived attractiveness and youthfulness and also enhanced competence and dominance overall. However, several effects varied according to perceiver nationality and target ethnicity. Trustworthiness showed a particularly context-dependent pattern. Chinese participants rated lightly made-up faces as more trustworthy than natural or heavily made-up faces, whereas British participants showed no significant differences in trustworthiness across makeup conditions. Additional interactions indicated that the effects of cosmetic enhancement on dominance, competence, and youthfulness also depended on the combination of perceiver nationality and target ethnicity. Discussion: These findings suggest that makeup-induced appearance cues can operate as social signals in facial impression formation. Cosmetic enhancement produced relatively general benefits for beauty- and vitality-related impressions, whereas its effects on status-, agency-, and trust-related judgments were more dependent on makeup intensity and the cultural and intergroup context in which the face was evaluated.

Sex differences in mate preferences are ubiquitous, having been evidenced across generations and cultures. Their prevalence and persistence have compellingly placed them in the evolutionarily adaptive context of sexual selection. However, the psycho-biological mechanisms contributing to their generation and maintenance remain poorly understood. As such a mechanism, sexual attraction is assumed to guide interest, desire, and the affinity toward specific partner features. However, whether sexual attraction can indeed explain sex differences in partner preferences has not been explicitly tested. To better understand how sex and sexual attraction shape mate preferences in humans we assessed how partner preferences differed across the spectrum of sexual attraction in a sample of 479 individuals that identified as asexual, gray-sexual, demisexual or allosexual. We further tested whether romantic attraction predicted preference profiles better than sexual attraction. Our results show that sexual attraction accounts for highly replicable sex differences in mate preferences for high social status and financial prospects, conscientiousness, and intelligence; however, it does not account for the enhanced preference for physical attractiveness expressed by men, which persists even in individuals with low sexual attraction. Instead, sex differences in physical attractiveness preference are better explained by the degree of romantic attraction. Furthermore, effects of sexual attraction on sex differences in partner preferences were grounded in current rather than previous experiences of sexual attraction. Taken together, the results support the idea that contemporary sex differences in partner preferences are maintained by several psycho-biological mechanisms that evolved in conjunction, including not only sexual but also romantic attraction.

Cross-cultural research has repeatedly demonstrated sex differences in the importance of partner characteristics when choosing a mate. Men typically report higher preferences for younger, more physically attractive women, while women typically place more importance on a partner’s status and wealth. As the assessment of such partner characteristics often relies on visual cues, this raises the question whether visual experience is necessary for sex-specific mate preferences to develop. To shed more light onto the emergence of sex differences in mate choice, the current study assessed how preferences for attractiveness, resources, and personality factors differ between sighted and blind individuals using an online questionnaire. We further investigate the role of social factors and sensory cue selection in these sex differences. Our sample consisted of 94 sighted and blind participants with different ages of blindness onset: 19 blind/28 sighted males and 19 blind/28 sighted females. Results replicated well-documented findings in the sighted, with men placing more importance on physical attractiveness and women placing more importance on status and resources. However, while physical attractiveness was less important to blind men, blind women considered physical attractiveness as important as sighted women. The importance of a high status and likeable personality was not influenced by sightedness. Blind individuals considered auditory cues more important than visual cues, while sighted males showed the opposite pattern. Further, relationship status and indirect, social influences were related to preferences. Overall, our findings shed light on the availability of visual information for the emergence of sex differences in mate preference.

This study compared mate retention strategies (MRS) in Brazil and in the UK, testing whether culture moderates the association between MRS and self-evaluated variables (e.g. mate value). Our findings demonstrated that women's MRS varied cross-culturally, with Brazilian women reporting to perform MRS more often than British women. Men's MRS did not vary between cultures. Additionally, culture moderated the association between MRS frequency and facial attractiveness disparity (the difference in attractiveness between partners) and mate value. This study presents initial evidence on the influence of culture on the frequency of MRS and its role in the association between self-evaluation and strategies designed to retain a partner.

Previous research has suggested that women using oral contraceptives show weaker preferences for masculine men than do women not using oral contraceptives. Such research would be consistent with the hypothesis that steroid hormones influence women’s preferences for masculine men. Recent large-scale longitudinal studies, however, have found limited evidence linking steroid hormones to masculinity preferences. Given the relatively small samples used in previous studies investigating putative associations between masculinity preferences and oral contraceptive use, we compared the facial masculinity preferences of women using oral contraceptives and women not using oral contraceptives in a large online sample of 6482 heterosexual women. We found no evidence that women using oral contraceptives had weaker preferences for male facial masculinity than did women not using oral contraceptives. These findings add to a growing literature suggesting that links between reproductive hormones and preferences are more limited than previously proposed.

Although widely cited as strong evidence that sexual selection has shaped human facial-attractiveness judgments, findings suggesting that women’s preferences for masculine characteristics in men’s faces are related to women’s hormonal status are equivocal and controversial. Consequently, we conducted the largest-ever longitudinal study of the hormonal correlates of women’s preferences for facial masculinity (N = 584). Analyses showed no compelling evidence that preferences for facial masculinity were related to changes in women’s salivary steroid hormone levels. Furthermore, both within-subjects and between-subjects comparisons showed no evidence that oral contraceptive use decreased masculinity preferences. However, women generally preferred masculinized over feminized versions of men’s faces, particularly when assessing men’s attractiveness for short-term, rather than long-term, relationships. Our results do not support the hypothesized link between women’s preferences for facial masculinity and their hormonal status.
