Children's understanding of dominance and prestige in China and the UK
Publication date: Available online 16 August 2019Source: Evolution and Human BehaviorAuthor(s): Anni Kajanus, Narges Afshordi, Felix WarnekenAbstractIndividuals can gain high social rank through dominance (based on coercion and fear) and prestige (based on merit and admiration). We conducted a cross-cultural developmental study and tested 5- to 12-year-olds, and adults in the UK and China, aiming to determine (a) the age at which children distinguish dominance and prestige, and (b) the influence of cultural values on rank-related reasoning. We specifically tested participants in China because of the value of prestigious in...

Singles of both sexes expedite reproduction: Shifts in sexual-timing strategies before and after the typical age of female menopause
Publication date: Available online 10 August 2019Source: Evolution and Human BehaviorAuthor(s): Samantha E. Cohen, Peter M. Todd, John K. Kruschke, Justin R. Garcia, Helen E. FisherAbstractHow do singles' strategies for engaging in sexual activity with a new partner vary across the adult lifespan? Using three large and independent demographically representative cross-sectional samples of heterosexual single adults in the U.S., we found that females approaching the typical age of menopause became less likely to establish relationship exclusivity prior to sexual activity with a new partner. However, after the typical age of ...

Who teaches children to forage? Exploring the primacy of child-to-child teaching among Hadza and BaYaka Hunter-Gatherers of Tanzania and Congo
Publication date: Available online 5 August 2019Source: Evolution and Human BehaviorAuthor(s): Sheina Lew-Levy, Stephen M. Kissler, Adam H. Boyette, Alyssa N. Crittenden, Ibrahim A. Mabulla, Barry S. HewlettAbstractTeaching is cross-culturally widespread but few studies have considered children as teachers as well as learners. This is surprising, since forager children spend much of their time playing and foraging in child-only groups, and thus, have access to many potential child teachers. Using the Social Relations Model, we examined the prevalence of child-to-child teaching using focal follow data from 35 Hadza and 38 B...

Sexual selection for low male voice pitch among Amazonian forager-horticulturists
Publication date: Available online 25 July 2019Source: Evolution and Human BehaviorAuthor(s): Kevin A. Rosenfield, Agnieszka Sorokowska, Piotr Sorokowski, David A. PutsAbstractPitch is the most perceptually salient feature of the voice, yet it is approximately five standard deviations lower in men than in women, a degree of sexual dimorphism exceeding that of all extant nonhuman apes. Evidence from Western samples suggests that low-frequency vocalizations may have augmented male mating success ancestrally by intimidating competitors and/or attracting mates. However, data are lacking from traditional societies living under ...

Patterns of mate choice consequently have power to direct the course of evolution. Here we provide evidence ...

Unleashing the BEAST: a brief measure of human social information use
Publication date: Available online 27 June 2019Source: Evolution and Human BehaviorAuthor(s): Lucas Molleman, Ralf Kurvers, Wouter van den BosAbstractSocial information enables individuals to reduce uncertainty and increase decision accuracy across a broad range of domains. Intriguingly, individuals and populations consistently differ in social information use. Understanding the underlying causes of this variation has proven challenging due to the lack of a standardized paradigm to quantify social information use. Here we introduce the BEAST (Berlin Estimate AdjuStment Task); a brief (∼5-min), simple, and incentive-compa...

Pride and shame: Key components of a culturally universal status management system
Publication date: Available online 21 June 2019Source: Evolution and Human BehaviorAuthor(s): Patrick K. Durkee, Aaron W. Lukaszewski, David M. BussAbstractWe apply recent adaptationist theories about the emotions “pride” and “shame” to the domain of hierarchical status and test the hypothesis that pride and shame are distinct components of a culturally universal status-management system. Using an international dataset containing ratings of the status impacts of 240 personal characteristics within 14 nations (N = 2751), we found that (i) the status impacts of personal characteristics were strongly intercorrelat...

Self sacrifice and kin psychology in war: threats to family predict decisions to volunteer for a women's paramilitary organization
Publication date: Available online 22 June 2019Source: Evolution and Human BehaviorAuthor(s): Lynch Robert, Lummaa Virpi, Loehr JohnAbstractThe conditions that propel humans to make sacrifices for groups of unrelated, and often unknown, individuals has received considerable attention across scientific disciplines. Evolutionary explanations for this type of sacrifice have focused on how men form strategic coalitions organized around kin networks and reciprocity when faced with out-group threats. Few studies, however, have analyzed how women respond to external threats. Using data from one of the largest female paramilitary ...
