We analyze data on social support and depression from 292 women in Uganda around the time of giving birth and find that a perceived lack of support, especially from the baby's father, is linked to a higher risk of depression in the mother. Moreover, we employ a quasi-experimental strategy to analyze the lesser-studied direction of the causality and estimate the effect of perinatal depression on different types of support (instrumental, informational, emotional, economic) a mother receives from kin, affines, and unrelated individuals. The results indicate that mothers at the threshold of depression obtain increased help from several individuals, especially the baby's father. Others who show a positive reaction include the woman's mother (maternal grandmother), father (maternal grandfather), and, to a minor extent, father-in-law (paternal grandfather), and cousins. Unrelated but physically close individuals (neighbors and friends) generally provide substantial help but do not react at the depression threshold. Overall, our findings provide some evidence in favor of the bargaining hypothesis for maternal depression.</p></div>","PeriodicalId":55159,"journal":{"name":"Evolution and Human Behavior","volume":"45 4","pages":"Article 106575"},"PeriodicalIF":3.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1090513824000382/pdfft?md5=0b399cf964028f34f01040e9a6948d3c&pid=1-s2.0-S1090513824000382-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141023190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present research addressed the relationship between masculine vocal parameters and immunity in two samples: young adult men from the US and Canada (<em>N</em> = 267) and adolescent males from Bolivia (<em>N</em> = 44). All participants provided saliva samples, assayed for a biomarker of mucosal immunity associated with respiratory disease resistance: secretory immunoglobulin-A (sIgA). Participants also contributed speech samples, analyzed for two sexually dimorphic aspects of the human voice: 1) fundamental frequency (<em>f</em><sub>o</sub>; perceived as pitch) and vocal tract length (VTL; estimated using formant frequencies). Multiple regression models were used to assess the association between masculine vocal parameters and sIgA. Results indicated that lower <em>f</em><sub>o</sub> and longer VTL were associated with higher sIgA levels. That is, both adult and adolescent males with more masculine voices showed better mucosal immunity (and therefore disease resistance) than those with less masculine voices. Although this accords with several previous studies on voice and sIgA, it contrasts with standard ICHH-derived predictions. We suggest that life-history theory provides a better conceptual framework for understanding the association between testosterone-dependent secondary sexual characteristics and immunity as it shifts the focus from immunosuppression to efficient immunoredistribution.</p></div>","PeriodicalId":55159,"journal":{"name":"Evolution and Human Behavior","volume":"45 4","pages":"Article 106590"},"PeriodicalIF":3.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141480989","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}

In two hunter-gatherer populations, the BaYaka and Agta, we take social capital as the determinant of outside options, using a generative model of the Nash bargaining problem and Bayesian multilevel logistic regression to test our hypothesis. We find no evidence for an association between social capital and division of leisure in either population. Instead, we find remarkable equality in the division of leisure time within households.

According to the “think manager-think male” model, leaders are stereotyped as male—and, in turn, as dominant—and this stereotype translates into preferences. However, status and leadership can be attained not only by dominance but also by prestige—a less sex-typed pathway. Five studies explored the relationship between leader stereotypes and preferences. University students spontaneously imagined both dominant and prestigious leaders as men (Study 1A, <em>N</em> = 148)—and this generalized across occupational domains (Study 1B, <em>N</em> = 220). However, they preferred women and prestigious leaders over men and dominant leaders. Study 2 (<em>N</em> = 2692) found this preference for female over male leaders using a large nationally representative U.S. sample from the Pew American Trends Panel. Study 3 (<em>N</em> = 461) experimentally replicated the preference for prestigious female over dominant male leader candidates among university students. In Study 4, (<em>N</em><span> = 952) online MTurk participants judged politicians from face photographs and again showed a preference for women, which may have partially been due to the inference that women are more likely to use prestige- over dominance-based leadership strategies. Collectively, findings suggest that the belief that people prefer “alpha male” leaders, which might discourage women from pursuing leadership roles and others from nominating them, needs to be updated.</span></p></div>","PeriodicalId":55159,"journal":{"name":"Evolution and Human Behavior","volume":"45 3","pages":"Pages 292-308"},"PeriodicalIF":5.1,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139668683","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}
