This article presents evidence suggesting that sex differences in aggression are universal, but that the differences are also highly susceptible to experiential modification. Following a “phylogenetic perspective” that emphasizes the interaction of genotype and experience, the author finds that boys are on average more aggressive than girls but adult males as a group are not significantly more aggressive than women.

This article investigates potential relationships between food deprivation, parental rejection, and personality development. Findings indicate that a series of adult personality characteristics (e.g. self evaluation and emotional responsiveness) are better predicted by parental rejection than by nutritional variables.

The purpose of this book is to introduce a conceptual and methodological perspective called the "universalist approach," and to use this approach in exploring the pancultural antecedents and affects of parental acceptance-rejection of children,

This chapter investigates the relationship between parental acceptance/rejection and personality characteristics of children and adults. The author analyzes evidence from two cross-cultural samples, one cross-national psychological sample, and one all-American sample. Only the tests using cross-cultural samples are reported here. Results suggest that parental rejection is related to certain personality characteristics of adults and children.

This study investigates cross-cultural determinants and consequences of parental affection and rejection. Findings indicate that accepted children are less hostile and dependent and have higher self-esteem in both childhood and adulthood. Additional findings suggest that children who experienced parental acceptance had higher emotional responsiveness, better world view, more emotional stability, generosity, and nurturance as adults.

This study examines the relationship between society and ideology focusing on gender status and religious beliefs. Hypotheses are tested to characterize the relationship and determine the impact of subsistence pattern on this interaction.

This study discusses childcare done by children. While no empirical hypotheses are tested, the authors identify some potential sociocultural and developmental correlates of childcare by children and provide relevant descriptive statistics. Possible correlates include mother-child relationships, conceptions and emergence of childhood stages, organization of play groups, development of social responsibility, sex differences, personality development, cognitive style and cognitive development, motivation and learning.

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.
