This study tests the claim that male and female investment in the socioemotional and economic aspects of family life are inversely related. Results suggest that this hypothesis is not supported, although a significant inverse relationship between male and female infant care does exist.

This study evaluates recent research on the roles of fathers in child development in hunting-gathering, simple farming, and pastoral communities around the world. The authors review previously conducted studies as well as highlight the varying theoretical approaches that many of these previous studies have taken.

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 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 article reviews aspects of cooperative breeding in humans and nonhumans. Life history characteristics, childcare helpers, and demographic implications of cooperative breeding are examined. Cross-cultural data is presented, though no empirical hypotheses are tested.

This study tests a broad "risk response" hypothesis: environmental risk can reduce parents' involvement and care which, through its effects on children's behavioral strategies later in life, ultimately produces a larger cultural model favoring risky behavior. Examinations of extramarital sex, aggression, theft, and witchcraft support this hypothesis, leading the authors to suggest that child development is the underpinning of cultural adaptation in the face of environmental change.

This study examines Parsons' and Bales' proposition that a universal feature of social structure is gender sex role specialization of tasks. Results suggest that women contribute substantially to the subsistence economy across many domains, casting doubt on such universality.

The author, Candace Alcorta, theorizes that low population density gives rise to a suite of factors that together are predictive of a society with internally directed population control strategies. In turn, there is an emphasis for a cooperative internal economic system among family, and a higher investment by fathers in their children.
