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.

Authors suggest that suicide is more likely to occur in contexts where an individual's social ties are threatened, weakened, or broken, causing social dislocation (thwarting-disorientation contexts). Results support this hypothesis.

The relationships of aggression and crime to variables of childhood experience, adult behavior, and social structure are cross-culturally analyzed.

The role of trees has long been limited to being sources of firewood or food in the archeological record. This article, however, aims to investigate the economic, cultural, and spiritual roles of trees through a comparative ethnographic analysis of 13 hunter-gatherer societies. The authors find that the relationships between trees and hunter-gatherers are deep and complex; trees are used for shade, protection, recreation, place-makers, and inhabitation and are often considered social and sacred beings.

The authors put forward a theoretical model called "personality integration of culture." At the heart of the model is the idea that psychological processes may help explain why certain aspects of culture are related to other aspects. To test this model they focus on theories and therapies regarding illness and they use psychoanalytic ideas on positive and negative fixation to suggest how differences in child-rearing customs may account for different ideas about the causes of illness. The strongest results relate to socialization anxiety in a particular area of socialization (e.g., oral, dependency, and aggression) amd respective causes of illness. Results regarding negative fixation are generally supported, whereas positive fixation is not.
