This paper is an investigation into the relationship between social differentiation as a proxy for societal 'development' and various categories of crime. A positive relationship is interpreted by the author as empirical cross-cultural support for Durkheim's theory that these two factors will increase together as parallel processes of 'sociocultural evolution'.

Textor summarizes cross-cultural findings on polygyny pertaining to cultural, environmental, psychological, and social phenomena.

The article tests theories that may explain why warfare frequency varies from society to society. The focus is on ecological problems, particularly different kinds of resource scarcity, but social and psychological theories are also tested with both bivariate and multivariate analyses. Because unpredictable disasters are such a strong predictor in nonstate societies, the authors theorize that war may mostly be caused by a fear of nature.

This chapter examines the variables that are associated with the evil eye belief cross-culturally. Results suggest that the evil eye belief is significantly associated with various socioeconomic and demographic variables. All hypotheses are supported.

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.
