The author reanalyzes hypotheses proposed by Lomax et al. (1968) that are based on Lomax's collection of cantometric data. Considering historical/regional variables, the author suggests that difusion and common history better explain certain musical features such as wordiness than functional and evolutionary processes. However, other Lomax findings are supported involving interlocked, contrapuntal singing and narrow nasal-voiced singing.

The authors test the relationship between disease prevalence and three different personality traits, with the expectation that pathogen load will be negatively associated with degree of sociosexuality, extraversion, and openness to experience. This prediction is supported by all three tests, which they theorize is an example of cultural behaviors adapting to reduce vulnerability to environmental risks.

This study examines the variability of siestas across cultures and considers how factors including climate, subsistence type, and disease susceptability relate to the presence or absence of siestas. The author finds a significant relationship between siestas and the presence of malaria.

This article investigates incest rules, proposing that they are instituted by rulers as a way of preventing wealth-concentration among non-ruling families. Three hypotheses are derived and supported with empirical analysis. Two alternative evolutionary hypotheses are discussed and dismissed by the author.

This study focuses on the relationship between pathogen prevalence and mate selection. Results show that increased pathogen prevalence is significantly associated with an increased importance in the physical attractiveness of potential mates.

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

This article presents a variety of findings regarding the nature and characteristics of humor and humorists, cross-culturally. It is a thorough preliminary study on the topic with a review of other work on humor and and outline of areas to be addressed by future research.

This article explores narcissism and child-rearing. The author presents a theory that, if a society’s structural pattern weakens the marital bond, the mother will be ambivalent toward the son who consequently will become narcissistic. This process would reinforce itself as it is repeated by each generation.

This study examines the proposition that the cross-cultural patterning of sexual beliefs and behaviors is neither entirely regular nor entirely irregular. The author uses cluster analysis to observe the relationships between several variables associated with sexuality.

This study tests the validity of two previous diachronic studies examining the relationship between subsistence strategy and sexual dimorphism of stature with synchronic data. The authors find that neither hypothesis is valid.
