This study examines the presence of parent-infant body contact at birth in non-industrial societies and its effects on subsequent infant care. The results show that immediate parent-infant contact is not common among most societies and does not have a significant effect on the quality of infant care.

This article tests a hypothesis regarding patterns of infant care in non-industrial societies. The authors find that a consistent pattern of infant care that emphasizes mother-infant contact exists among hunter-gatherers and other non-industrial societies. These infant care practices differ from those found in the United states that do not promote extensive infant-mother contact.

This study tests competing theories about whether it is men, women, or parents who benefit most from restricting female premarital sex (FPS) in a global sample of 128 non-industrial societies. The study found support for the idea that multiple parties benefit from restrictions on FPS -- specifically FPS is more restricted in societies intolerant of extramarital sex and where men transfer property to their children (male control), as well as where marriages are arranged by parents (parental control). They also found that major predictors of FPS appear to be paternity uncertainty and parent-offspring conflict. Furthermore, the study found that multiple factors such as social roles, rather than stereotyped sex roles, are a more useful approach in understanding FPS restrictions and these restrictions.

This paper presents tests of the relationships between tropical African agriculture and cultural variables regulating reproduction in order to examine a theory which suggests that the lagging or absence of tropical Africa's demographic transition is the result of pervasive 'pro-natal' cultural practices. Strength of association between these factors and non-plow agriculture, the traditional method of farming in tropical Africa, leads the authors to suggest that women's larger subsistence role in these societies favors extended family households in which child-rearing responsibilities can be shared, and polygynous marriage systems in which co-wives can contribute substantially to the family's labor productivity. These, along with erosion of regulations on postpartum sex and birth spacing which were prevalent prior to modernization, are identified as characterstics which have and will continue to resist fertility decline.

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.

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.

This article presents two evolutionary models that may explain relationships between war and socialization of children: the "environmentally contingent reproductive strategy" (ECRS) model put forward by Draper and Harpending (1982), and a model put forward by Carol and Melvin Ember. Results do not provide support for the hypotheses involving father-infant sleeping proximity derived from the ECRS model. The authors also find some inconsistencies with their own model.
