Brown's (1963) three hypotheses on female puberty rites were tested. After presenting an adjustment for data quality control, the author demonstrates that Brown's (1963) relationships became insignificant. Female physiology as symbolized by menstruation is suggested as a better predictor for female puberty rites.

This article draws on psychoanalytic theory and a previous study by Whiting (1964) to test the relationship between parent-child sleeping arrangements, particularly the implied social distance of fathers, and the presence of circumcision for males. Circumcision is assumed to be a social correction for mother-oriented personality in sons.

A path analytic model is presented to explain male puberty rites. The evidence presented supports the idea that as a whole, male puberty rites may be seen as the means of maintaining the bisexual nature of human society.

This article presents a reanalysis of a study by Ember (1978) examining the predictors of men's heterosexual fear. The author finds that Ember's model is not upheld and presents a new model of men's heterosexual fear using path analysis. Results suggest that mother-child sleeping arrangements and food shortage are directly related to men's heterosexual fear.

The purpose of this article is to examine circumcision and segregation of males at puberty. It is suggested that when the son has insufficient contact with his father due to the separation caused by polygynous relationships, the son may develop a feminine personality. The significance of this is compared with the significance of a close mother-son relationship.

The significance of the son's insufficient contact with his father during infancy in regard to circumcision and segregation is examined. This article suggests that it is not the long postpartum sexual taboo but the separation of each co-wife that is instrumental in bringing about circumcision and segregation. Expands on Kitahara 1974.

This article examines the relationship between polygynous living quarter arrangements and the presence or absence of circumcision and segregation of males at puberty. The amount of contact between the father and son is also examined as a factor.

The purpose of this paper is to examine female puberty rites and to suggest that such rites may be explained in terms of female physiology, as symbolized, for example, by menstruation.

This article investigates the sexual division of labor between adults and children. Data analysis suggests that children usually perform tasks appropriate for an adult of the same gender, but boys will often perform women’s tasks while girls generally do not perform men’s tasks. Thus, women tend to benefit more from children’s labor.

This article presents theory and hypothesis tests that suggest that the decline of women's contribution to intensive agriculture is related to increases in fertility and domestic work associated with cereal crops. Additionally, men in agricultural societies are less likely to invest time in hunting and warfare, so their contribution of agricultural labor relative to women's increases.
