The author claims that variance in sociocultural variables can be mostly be attributed to associations that are not cross-cultural. Although some patterns are universal, many social patterns occur on a regional, rather than worldwide, scale. This study presents a factor analysis of sociocultural variables that supports these claims.

This chapter examines the relationship between singing behavior, specifically vocal rasp, and sex-role differences. Results suggest that conformity training is negatively associated with the use of vocal rasp. Results also suggest that women are more likely to sing with vocal rasp in societies where they make a more significant contribution to subsistence.

The author reanalyzes hypotheses proposed by Lomax et al. (1968) that are based on Lomax's collection of cantometric data. Considering historical/regional variables, the author suggests that difusion and common history better explain certain musical features such as wordiness than functional and evolutionary processes. However, other Lomax findings are supported involving interlocked, contrapuntal singing and narrow nasal-voiced singing.

The complex set of beliefs and practices in which the cult of the guardian spirit consisted is examined.

This article explores determinants of non-classical polyandry, which the authors assert is more common than is usually conveyed. Results indicate that societies with non-classical polyandry tend to be small scale and egalitarian, practice hunting and gathering or horticulture, and have a male-skewed sex ratio. Overall polyandry is thought to add to the reproductive fitness of both men and women.

This paper investigates correlations between social structure and the pattern of kindship nomenclature. Results suggest that lineage nomenclatures are associated with several aspects of social structure, including unilineal descent, the domestication of plants and animals and inheritance.

This study challenges an earlier paper's claim that matrilocal residence predicts the development of girls' puberty rites. The author suggests that girls' puberty rites may in fact predate matrilocality in some locations.

This article explores biological, psychological, and social explanations for menstrual taboos. Attention is paid to the role of men in rituals associated with reproduction--i.e. before, during and after childbirth, as well as during girls' puberty rites.

This article explores narcissism and child-rearing. The author presents a theory that, if a society’s structural pattern weakens the marital bond, the mother will be ambivalent toward the son who consequently will become narcissistic. This process would reinforce itself as it is repeated by each generation.

This article attempts to construct an empirically-based typology of social structure. Marital structure, government, food production, and stratification are among the factors considered.
