This article examines sex differences in sports and games of strategy and chance. Results indicated large differences in participation by gender, especially for combat and hunting sports and in patriarchal societies. The possible cross-cultural universality of this trend is discussed.

This paper presents tests of the relationships between tropical African agriculture and cultural variables regulating reproduction in order to examine a theory which suggests that the lagging or absence of tropical Africa's demographic transition is the result of pervasive 'pro-natal' cultural practices. Strength of association between these factors and non-plow agriculture, the traditional method of farming in tropical Africa, leads the authors to suggest that women's larger subsistence role in these societies favors extended family households in which child-rearing responsibilities can be shared, and polygynous marriage systems in which co-wives can contribute substantially to the family's labor productivity. These, along with erosion of regulations on postpartum sex and birth spacing which were prevalent prior to modernization, are identified as characterstics which have and will continue to resist fertility decline.

This study uses evolutionary theory to hypothesize about the association between age, gender, and gambling. Results suggest that males are more frequent and riskier gamblers than females and that young adults are more likely to have gambling problems than people of other age classes.

The authors explore coalitional play fighting (in which teams of at least two play against each other to achieve a goal) across hunter-gatherer societies, with the theory that play of this type may be a mechanism for assessing strength and utility for future defense or warfare. When played against other communities, they propose coalitional play fighting can also serve to gauge strength of potential allies or formidability of potential enemies. In order to test their theories, they predict that, despite the large energy cost and risk of sports associated with coalitional play fighting, these types of games will be widespread in hunter-gatherer societies. In addition, they predict that of those exhibiting coalitional play fighting, many will play against other communities. In support of their hypotheses, they find that 54% of hunter-gatherer societies examined exhibit coalitional play fighting, of which 81% play against other communities.

This study examines differences in the ease of socialization for male and female children in preindustrial societies. Results support the hypothesis that the socialization of females is accomplished more easily than the socialization of males.
