This study examines the predictors of arranged marriage versus marriage for love. Several predictions are supported and results uphold the hypothesis that "societies promote the method of marriage contract enforcement best adapted to available production technology, incentives to misbehave, and methods of coercion."

This study tests competing theories about whether it is men, women, or parents who benefit most from restricting female premarital sex (FPS) in a global sample of 128 non-industrial societies. The study found support for the idea that multiple parties benefit from restrictions on FPS -- specifically FPS is more restricted in societies intolerant of extramarital sex and where men transfer property to their children (male control), as well as where marriages are arranged by parents (parental control). They also found that major predictors of FPS appear to be paternity uncertainty and parent-offspring conflict. Furthermore, the study found that multiple factors such as social roles, rather than stereotyped sex roles, are a more useful approach in understanding FPS restrictions and these restrictions.

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.

This article examines child-training through children's display of individualistic orientations (self-reliance, achievement, and general independence) and/or group orientations (responsibility, nurturance, and obedience). Five sub-categories measure whether each orientation is linked to a child's experience of general pressure or performance anxiety/conflict. Together, these orientations their sub-categories total 30 variables that were correlated; differences in gender were also examined. Results indicate that child-rearing pressure to act one way predicts pressure to act in other ways, and this pattern of interaction between variables did not vary by gender.
