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.

This paper is concerned with the variation in sexual behavior in humans. Authors test hypotheses regarding the relationships between sexual behaviors and beliefs concerning sex.

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.

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.

This study tests predictions of homosexuality. Results suggest that homosexuality is significantly associated with father-son contact.

This study employs a psychological theory and builds on the holocultural literature on male homosexuality. Two hypotheses relating homosexual behavior among men to social constructs for sexuality (the couvade, male transvestism) are derived from a study by Munroe (1980). The hypotheses are tested and supported in a sample of cultures drawn from Munroe's codes and the Human Relations Area Files.

This study explores the extent to which heterosexual sex, love, and intimacy are interrelated and the degree to which the sexual revolution has had a positive or negative impact on male-female relationships. The author employs a correlation matrix to examine the interrelationships of several variables related to aloofness and intimacy in the sexual and non-sexual aspects of heterosexual relationships. Results suggest that the sexual revolution has had some positive effects on male-female relationships, but also that sexual behavior does not predict the degree to which marriages are intimate or aloof. Results also show little support for the hypothesis that marital aloofness is related to hypermasculinity.

This study uses logistic regression to test the relationship between homosexuality and ecological and psychosocial variables. Significant associations were found between the frequency of homosexuality and type of agriculture, the occurrence of gathering, and psychosocial stressors in women's lives.

This study examines the theory that transvestism is a way for boys to escape the male role. Munroe and Munroe use male contribution to subsistence as a new measure of a "rigorous male role." Findings suggest an association between male predominance in subsistence and presence of transvestism.

"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.
