In pre-registered exploratory analyses, we further find no statistically significant associations between menstrual cycle phase or hormone levels and facial preferences.

Here, we tested two distinct hypotheses about how people might use reputational information to achieve social goals. <em>Indirect Reciprocity</em> <em>theory</em> entails the hypothesis that people share information about themselves and others accurately in order to reward cooperators and punish defectors. In contrast, <em>Reputation-Based Partner Choice</em> theory proposes that people share, withhold, and distort information about themselves and others in order to secure high-quality cooperation partners. We found that subjects were more likely to share information about others' (and their own) previous generosity if they themselves had been generous rather than greedy. Previously generous people were most likely to gossip—and previously greedy people were least likely —under conditions in which sharing and withholding gossip, respectively, were in their material interest. Likewise, previously generous people were most likely to share honest gossip—and previously greedy people were most likely to share dishonest gossip—when it was in their material interest. Finally, previously generous people were less likely than previously greedy people to share dishonest gossip that yielded a competitive advantage. Although these results fit more comfortably with Reputation-based Partner Choice theory than with Indirect Reciprocity theory as commonly understood, nearly 30 % of subjects shared information even when it did not pay to do so. This finding suggests that people's decisions about sharing reputational information are not driven exclusively by short-term material considerations, although we did not explore the self-interested desire to avoid the social cost of being caught lying.</div></div>","PeriodicalId":55159,"journal":{"name":"Evolution and Human Behavior","volume":"46 5","pages":"Article 106711"},"PeriodicalIF":3.0,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144314566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accordingly, individual fighting ability has been shown to regulate the outcome of contests: All else equal, more formidable individuals claim a larger share of disputed resources, and less formidable individuals defer to their claims. The human ability to cooperate in groups complicates these interactions because a coalition of individuals can take resources from an individual that none of them could dominate when acting alone. We propose that the prevalence of male coalitional aggression in humans selected for psychological mechanisms that track how much coalitional support is immediately available to men when they are contesting a resource and use this information to regulate decisions about how to divide it. Specifically, men with coalitional allies present should be motivated to press their self-interest more than men who are acting alone—even if the solitary man has allies elsewhere. Experiments using economic games in a university lab setting were employed to test this coalitional support hypothesis. Across six experiments employing three different economic games (total <em>n</em> = 496), coalitional support consistently regulated men's—but not women's—choices. These results suggest that coalitional support is an important factor regulating resource division in men. The fact that women pressed their self-interest, but did so whether allies were present versus absent, suggests that women's coalitional psychology was designed by different selection pressures than men's.</div></div>","PeriodicalId":55159,"journal":{"name":"Evolution and Human Behavior","volume":"46 5","pages":"Article 106715"},"PeriodicalIF":3.0,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144298817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study explored how Colombian women's preferences for masculinized male faces are influenced by relationship context and resource availability, as well as their individual experiences of intimate partner violence (IPV). Using a forced-choice paradigm with eye-tracking, we assessed visual attention and face-choice in 293 cisgender heterosexual Colombian women recruited through social media adverts. Participants were assigned to either a high or low resource availability condition and selected preferred partners for short- and long-term relationships. Self-reported IPV experiences were also collected. Results revealed a strong preference for masculine faces in both relationship contexts, with higher preference in long-term scenarios and under low resource availability. However, higher frequencies of physical IPV predicted a lower preference for masculinity, particularly in long-term and high-resource contexts. These exploratory findings suggest that while Colombian women generally favor masculine traits, socio-contextual factors, such as resource availability and IPV experiences, significantly modulate these preferences. The study highlights the complex interplay between individual, evolutionary, and socio-ecological factors in shaping mate preferences, suggesting that masculinity is valued depending on relationship goals, resource conditions, and individual experiences like IPV.</div></div>","PeriodicalId":55159,"journal":{"name":"Evolution and Human Behavior","volume":"46 4","pages":"Article 106707"},"PeriodicalIF":3.0,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144223386","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current study aimed to investigate (1) how children weigh the importance of shared social category and shared preferences as cues to potential social partnerships, and (2) whether the weight that children place on shared preferences depends on their rarity. We assessed third-party friendship inferences in 106 children (ages 4 to 12) in Japan by having them predict friendships between characters based on their gender and preferences. Children privileged shared preferences over shared gender, predicting that a character would be friends with an other-gender character who shared their preference than a same-gender character who did not. Further, this tendency to prioritize shared preferences was slightly stronger when the preferences were rare rather than common. When multiple types of similarity cues are available, it may be adaptive to select social partners based on unique similarities which signal that the individual offers irreplaceable benefits that are not easily supplied by others.</div></div>","PeriodicalId":55159,"journal":{"name":"Evolution and Human Behavior","volume":"46 4","pages":"Article 106708"},"PeriodicalIF":3.0,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144205008","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 130 children aged 4 to 7 were shown two distinct methods to acquire stickers at a local science museum: one involving causally irrelevant ritualistic actions and the other, instrumentally functional actions. Both methods resulted in giving up the opportunity to win more stickers. Results showed that children prioritised copying rituals over functional actions, even at a material cost.
