This study examines husband-wife relationships, specifically rooming and sleeping arrangements, as they relate to variables such as infant care, subsistence, residence, and cultural complexity. Several hypotheses are tested and all are supported.

This study examines several correlates of the shape of floor plans of dwellings. Authors find that "whether a culture is settled or nomadic, the form of its family and the presence or absence of status distinctions are related to its house type, and the house types can in turn be inferred from the floor plan." Curvilinear houses are associated with polygyny and nomadism and rectilinear houses are associated with sedentarism, extended families, and status distinctions.

This article discusses maidenhood, the period of time between menarche and marriage. In-depth case illustrations provide insights into the social, technological, and environmental factors that affect the length of maidenhood. The authors use cross-cultural evidence to challenge contemporary American assumptions that teenagers are too young to be mothers and that young women should focus on a career before marriage and child-rearing. A variety of descriptive statistics are also presented.

This chapter examines infant carrying practices across cultures. The author suggests that infant carrying practices are affected by both climate and history. Findings indicate regional patterns in infant carrying practices and in the borrowing of infant carrying practices within regions. Results support the hypothesis.

This chapter examines how sorcery, sin, and the superego function in societies to uphold taboos and other forms of social control. The author also explores the child-rearing conditions that are necessary to produce and maintain these cultural mechanisms. Several hypotheses are tested and all are supported.

This study examines the relationship between infant stress and early menarche. Empirical analysis suggests that stress in infancy, such as mother-infant separation and head-shaping, are associated with early menarche.

Using a sample of 313 societies classified within 24 language phyla, authors put forward a statistical model based on climate data [specifically focused on the 10°C (50°F) winter temperature isotherm] to explain why dispersion of preindustrial language phyla is remarkably homogeneous even despite heterogeneous geographical dispersion of sampled preindustrial cultural groups. They suggest that temperature has been a barrier to migration.

This study explores ecological reasons that might explain why boys are mostly circumcised in tropical regions, particularly in Africa and the insular Pacific. The author postulates a long causal chain linking: 1) tropical climate to the growing of root and fruit crops; 2) the need to keep babies on mother's milk for as long as possible where the adult diet is lacking in protein; 3) a long post-partum sex taboo as a way to space births; 4) the practice of polygyny (and associated mother-child sleeping) in the face of a long sex taboo; 5) patrilocal residence; and 6) male initiation ceremonies which are believed to result from the combination of mother-child sleeping, the long poast-partum sex taboo and patrilocal residence.

Building on comparative study of the Mormons, Texans, and Zuni in the Rimrock area of Southwestern U.S., the authors cross-cultural test some hypotheses cross-culturally.
