This study investigates the conceptual frameworks involved in infanticide. Authors first examine data on infanticide and birth ceremonies, particularly the timing of these events and the infant and adult involved in each. Authors also examine reasons for performing infanticide, including illegitimacy, unwanted children, and excess children, finding them similar to reasons for performing abortion. Population control and implications for children's and women's status are also discussed.

This paper is concerned with the variation in sexual behavior in humans. Authors test hypotheses regarding the relationships between sexual behaviors and beliefs concerning sex.

This article examines dream symbols that are classified by gender. Tests of six languages from six branches suggest that objects that appear as male or female dream symbols are represented by corresponding gendered words (i.e. masculine or feminine nouns).

This article proposes that differences in diet may account for the presence or absence of morning sickness in a society. Data suggest that morning sickness is not a universal symptom of pregnancy, and there are significant differences in foods consumed where morning sickness does not occur, including more maize, fats, and vegetables.

This book chapter examines relationships between the child-training behavior of mothers and the responsibilities of both mothers and others. Child-training behavior is also examined in relation to single and multiple family dwellings.

This article investigates the relationships between culturally defined frustrating agents and various types of culturally defined targets of aggressive response.

This article tests hypotheses about the relationship between how the general anticipations of pain in develop in children and the formal belief systems of a society. The authors posit that beliefs in malevolent supernatural beings reflect punitive child rearing practices and beliefs in benevolent supernatural being relfect nurturing child rearing practices. Results generally support this hypothesis.

This study explores predictors of variation in two dimensions of marital residence patterns among hunter-gatherers: 1) the tendency toward patrilocality versus matrilocality and 2) the tendency toward unilocality versus bilocality.

The present research investigates food sharing and labor sharing practices of 98 nonindustrial societies. The aims are to: 1) document the frequency and scope of sharing, and 2) test the theory that greater sharing is adaptive in societies subject to more resource stress (including natural hazards).

This article uses the Standard Cross-Cultural Samples to test the relationship between disease and economic growth among sub-Saharan African societies. The authors suggest that a higher disease prevalence limits social integration and economic development since pre-colonial times. The variable measuring economic growth is the complexity of large or impressive structures. The hypotheses are that 1) pathogen stress is negatively correlated to the presence of complex buildings, and 2) pathogen stress is positively correlated to increased ethnic diversity. The results support both hypotheses, and there are additional results, like 1) the negative correlation between pathogen stress and current income per capita and 2) the negative correlation between the increased ethnic diversity and current income per capita. Overall, this article shows the robust relationship between disease and economic development.
