This book discusses the characteristics of adolescence cross-culturally and examines the differences in the adolescent experience for males and females. Several relationships are tested in order to gain an understanding of cross-cultural patterns in adolescence.

Drawing on various theories regarding the sexual division of labor, Broude examines the relationship between task differentiation by sex and gender-related behaviors/customs.

This article examines correlates of premarital sexual norms cross-culturally. Several explainations of restrictiveness of premarital sex are reviewed, and results indicate that accessibility of caretakers in childhood, class stratification and cultural complexity are all related to premarital sexual norms.

This book chapter builds on Horton's 1943 psychoanalytical study of drunkenness. The author tests an overall theory that drunkenness, which facilitates personal and uninhibited interactions, is more acceptable, and therefore prevalent, in societies with loose, rather than rigid, social relationships. Indicators of social rigidity, such as strict socialization or male dominance through patrilocality, are tested for relationships to drunkenness.

The authors test the relationship between disease prevalence and three different personality traits, with the expectation that pathogen load will be negatively associated with degree of sociosexuality, extraversion, and openness to experience. This prediction is supported by all three tests, which they theorize is an example of cultural behaviors adapting to reduce vulnerability to environmental risks.

"The kin selection hypothesis posits that male androphilia evolved because androphilic males invest more in kin, thereby enhancing inclusive fitness." However, increased kin-directed altruism has only been seen in societies that exhibit transgendered male androphilia. To test the validity of the kin selection hypothesis for male androphilia, the authors examine the relationship between ancestral sociocultural conditions, access to kin, and societal reactions to homosexuality and the expression of male androphilia as transgendered or non-transgendered. They find that ancestral sociocultural conditions and bilateral and double descent systems were more common in transgendered than non-transgendered societies.

This study argues that different types of homosexuality must be examined separately. Authors focus on mentorship and pathic homosexual behavior and test factors that are associated with these two types of behavior.

The author performs tests of hypothesized relationships between arranged marriage and various forms of non-sanctioned mate choice. Overall, the author theorizes that where marriages are arranged, mate choice will be found in higher prevalence of premarital sex, extramarital sex, and rape. Most tests support these relationships in the hypothesized directions, suggesting that strict regulation of marriage provides parents with some, but far from complete control over the mate choice of their offspring.
