    From Storytelling to Facebook.Alberto Acerbi - 2022 - Human Nature 33 (2):132-144.
    Cultural evolution researchers use transmission chain experiments to investigate which content is more likely to survive when transmitted from one individual to another. These experiments resemble oral storytelling, wherein individuals need to understand, memorize, and reproduce the content. However, prominent contemporary forms of cultural transmission—think an online sharing—only involve the willingness to transmit the content. Here I present two fully preregistered online experiments that explicitly investigated the differences between these two modalities of transmission. The first experiment examined whether negative content, (...)

    Being More Educated and Earning More Increases Romantic Interest: Data from 1.8 M Online Daters from 24 Nations.Peter K. Jonason & Andrew G. Thomas - 2022 - Human Nature 33 (2):115-131.
    How humans choose their mates is a central feature of adult life and an area of considerable disagreement among relationship researchers. However, few studies have examined mate choice around the world, and fewer still have considered data from online dating services. Using data from more than 1.8 million online daters from 24 countries, we examined the role of sex and resource-acquisition ability in mate choice using multilevel modeling. We then attempted to understand country-level variance by examining factors such as gender (...)

    Let’s Play at Digging.Ana Mateos, Guillermo Zorrilla-Revilla & Jesús Rodríguez - 2022 - Human Nature 33 (2):172-195.
    Extractive foraging tasks, such as digging, are broadly practiced among hunter-gatherer populations in different ecological conditions. Despite tuber-gathering tasks being widely practiced by children and adolescents, little research has focused on the physical traits associated with digging ability. Here, we assess how age and energetic expenditure affect the performance of this extractive task. Using an experimental approach, the energetic cost of digging to extract simulated tubers is evaluated in a sample of 40 urban children and adolescents of both sexes to (...)

  4. Paternity Uncertainty and Parent–Offspring Conflict Explain Restrictions on Female Premarital Sex across Societies.Gabriel Šaffa, Pavel Duda & Jan Zrzavý - 2022 - Human Nature 33 (2):215-235.
    Although norms of premarital sex vary cross-culturally, the sexuality of adolescent girls has been consistently more restricted than that of adolescent boys. Three major theories that attempt to explain restrictions on female premarital sex concern male, female, and parental control. These competing theories have not been tested against each other cross-culturally. In this study, we do this using a sample of 128 nonindustrial societies and socioecological predictors capturing extramarital sex, paternal care, female status, sex ratio, parental control over a daughter’s (...)

    Intra- and Intersexual Mate Competition in Two Cultures.Scott W. Semenyna, Francisco R. Gómez Jiménez & Paul L. Vasey - 2022 - Human Nature 33 (2):145-171.
    The present study examined women’s mate competition tactics in response to female and feminine-male rivals in two cultures in which competition against both occurs. In Samoa and the Istmo Zapotec, women not only compete with other women but also compete with rival feminine males in order to access/retain the same masculine men as sexual/romantic partners. Using a mixed-method paradigm, women were asked about their experiences of intra- and intersexual mate competition, and these narratives were recorded. The tactics reportedly employed by (...)

    Fertility Dynamics and Life History Tactics Vary by Socioeconomic Position in a Transitioning Cohort of Postreproductive Chilean Women.Pablo José Varas Enríquez, Luseadra McKerracher & Nicolás Montalva Rivera - 2022 - Human Nature 33 (2):83-114.
    Globally, mortality and fertility rates generally fall as resource abundance increases. This pattern represents an evolutionary paradox insofar as resource-rich ecological contexts can support higher numbers of offspring, a component of biological fitness. This paradox has not been resolved, in part because the relationships between fertility, life history strategies, reproductive behavior, and socioeconomic conditions are complex and cultural-historically contingent. We aim to understand how we might make sense of this paradox in the specific context of late-twentieth-century, mid–demographic transition Chile. We (...)

    The Early Expression of Blatant Dehumanization in Children and Its Association with Outgroup Negativity.Wen Zhou & Brian Hare - 2022 - Human Nature 33 (2):196-214.
    Dehumanization is observed in adults across cultures and is thought to motivate human violence. The age of its first expression remains largely untested. This research demonstrates that diverse representations of humanness, including a novel one, readily elicit blatant dehumanization in adults and children. Dehumanizing responses in both age groups are associated with support for outgroup inferiority. Similar to the link previously observed in adults, dehumanization by children is associated with a willingness to punish outgroup transgressors. These findings suggest that exposure (...)

    Why People Keep an Intimate Relationship.Menelaos Apostolou - 2022 - Human Nature 33 (1):62-81.
    Forming long-term intimate relationships constitutes an important aspect of human nature. Within the context of an evolutionary theoretical framework, the current research has attempted to investigate what motivates people to keep an intimate relationship. Using a combination of qualitative research methods in a sample of 131 Greek-speaking participants, 58 reasons that motivated individuals to keep their intimate relationship were identified. Using quantitative research methods in a sample of 789 Greek-speaking participants who were in an intimate relationship, these reasons were classified (...)

    Political Alliance Formation and Cooperation Networks in the Utah State Legislature.Connor A. Davis, Daniel Redhead & Shane J. Macfarlan - 2022 - Human Nature 33 (1):1-21.
    Social network analysis has become an increasingly important tool among political scientists for understanding legislative cooperation in modern, democratic nation-states. Recent research has demonstrated the influence that group affinity and mutual exchanges have in structuring political relationships. However, this literature has typically focused on political cooperation where costs are low, relationships are not exclusive, and/or partisan competition is high. Patterns of legislative behavior in alternative contexts are less clear and remain largely unexamined. Here, we compare theoretical expectations of cooperation in (...)

    Four Puzzles of Reputation-Based Cooperation.Francesca Giardini, Daniel Balliet, Eleanor A. Power, Szabolcs Számadó & Károly Takács - 2022 - Human Nature 33 (1):43-61.
    Research in various disciplines has highlighted that humans are uniquely able to solve the problem of cooperation through the informal mechanisms of reputation and gossip. Reputation coordinates the evaluative judgments of individuals about one another. Direct observation of actions and communication are the essential routes that are used to establish and update reputations. In large groups, where opportunities for direct observation are limited, gossip becomes an important channel to share individual perceptions and evaluations of others that can be used to (...)

    Voices as Cues to Children’s Needs for Caregiving.Carlos Hernández Blasi, David F. Bjorklund, Sonia Agut, Francisco Lozano Nomdedeu & Miguel Ángel Martínez - 2022 - Human Nature 33 (1):22-42.
    The aim of this study was to explore the role of voices as cues to adults of children’s needs for potential caregiving during early childhood. To this purpose, 74 college students listened to pairs of 5-year-old versus 10-year-old children verbalizing neutral-content sentences and indicated which voice was better associated with each of 14 traits, potentially meaningful in interactions between young children and adults. Results indicated that children with immature voices were perceived more positively and as being more helpless than children (...)
