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.

Textor summarizes cross-cultural male initiation rites findings pertaining to cultural, environmental, psychological, and social phenomena.

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.

Authors investigate the prevalence of male homosexual preference (MHP) cross-culturally. They employ four models to test the link between level of social stratification and the probability of observing male homosexual preference (MHP). Authors believe that this link supports the hypergyny hypothesis, which proposes that increased social stratification allows for some sort of factor that improves functional female fertility, perhaps through marriage to men of higher social classes. This would thereby allow more access to resources and consequently the ability to support a greater number of more reproductively-successful offspring. Authors do not make a causal link, however; rather, social stratification may be associated with a yet-undetermined pleiotropic factor that is somehow positive despite its cost on functional male fertility.

Researchers sampled 48 societies cross-culturally to study the genetic survival of male homosexual preference, which is argued to be deleterious in nature due to its fertility costs. The researchers test for a sexually antagonistic factor that would produce a pleotropic advantage, such as male homosexual preference increasing the reproduction of sisters. Utilizing theoretical models, researchers assert that the survival of male homosexual preference is a result of the positive association between social stratification and discriminate female hypergyny due to selection for attractiveness in females.

This study attempts to replicate earlier findings regarding transvestism using a larger sample and a different index of sex distinctions. It is asserted that societies that maximize sex distinctions will not have institutionalized male transvestism.

The preindustrial family structure instilled family members with values that passed through generations and impact today's political attitudes and policies. Three studies show that ancestral kinship structure predicts right-wing cultural attitudes and, among those less engaged in politics, left-wing economic attitudes (though controlling for the country of residence removes this prediction). Stronger country-level ancestral kinship strength also increases anti-LGBT policies and welfare spending. This work indicates that political beliefs are rooted in the value systems and familial institutions created by our forebears.

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 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.
