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.

This paper investigates love magic, proposing that it is a form of indirect communication in the development of male-female bonds. Findings support the hypothesis.

Textor summarizes cross-cultural male initiation rites findings pertaining to cultural, environmental, psychological, and social phenomena.

This chapter attempts to explain why the number, importance, and duration of food and sex taboos during pregnancy vary cross-culturally. The author hypothesizes that differences in child socialization will be associated with differences in food taboos, and differences in sexual behavior and sanctions will be associated with sex taboos. Results support the hypotheses.

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

This paper presents research on the factors that promote romantic love as a basis for marriage in non-industrial societies. After a discussion of the previous literature on romantic love in ethnographic societies, the authors used the SCCS, EA, and data from eHRAF to create a data set of 109 cultures and then utilized multiple ordinal regression to test the relationship between different types of families and post-marital residence practices and the importance of romantic love in marriage. The findings show that monogamy is significantly correlated with romantic love, while nuclear family organization and neolocal post-marital residence are not significantly correlated. The presence of polygyny is found to lower the probability of romantic love being a basis for marriage. These findings contradict previous research, which found a relationship between non-neolocal post-marital residence and the presence of romantic love in marriage.

This article examines reasons for the variation in sexual foreplay practices cross-culturally. Results suggest that exclusive mother-child sleeping arrangements is significantly associated with the presence of foreplay.

The author attempts to test the "Oedipus-complex" hypothesis--the psychoanalytic idea that under certain conditions (such as the long-post partum sex taboo) males are sexually attracted to their mothers and as a consequence certain fears and anxiety are generaated. The hypothesis is tested at the societal-level using ethnographic data.

The author hypothesizes that physical violence is strongly related to the deprivation of physical pleasure.

Results support the hypothesis.
