This study focuses on obsessive-compulsive disorder in relation to ritual. Features of OCD are coded and analyzed in the contexts of ritual, work and other activities.

This study seeks correlations between social variables and linguistic variables, including the following ten speech patterns: repetitiveness, long-windedness, drawl, charm and variability, amount of pausing, sharing of air time, tension, noisy qualities, breath control, and forcefulness. Many associations are discussed, particularly those involving societal complexity, sex roles, and singing and dancing.

This chapter explores the relationship between cultural complexity and song. Several measures of cultural complexity are correlated with different aspects of singing. All hypotheses are supported.

This chapter examines the relationship between social cohesion (measured using variables like subsistence type, stable work teams, and settlement patterns) and musical cohesion. All hypotheses are supported.

This chapter suggests that dance styles reflect cultural traits. The authors hypothesize that certain aspects of cultural complexity predict several types of dance movement. Hypotheses are supported.

A large-scale comparative study of folk songs around the world employing systematic measures (cantometrics). The aim was not just to describe variation but to test hypotheses about the relationships between song style and societal structures. Dance was also considered.

This study explores predictors of variation in two dimensions of marital residence patterns among hunter-gatherers: 1) the tendency toward patrilocality versus matrilocality and 2) the tendency toward unilocality versus bilocality.

The present research investigates food sharing and labor sharing practices of 98 nonindustrial societies. The aims are to: 1) document the frequency and scope of sharing, and 2) test the theory that greater sharing is adaptive in societies subject to more resource stress (including natural hazards).

This article uses the Standard Cross-Cultural Samples to test the relationship between disease and economic growth among sub-Saharan African societies. The authors suggest that a higher disease prevalence limits social integration and economic development since pre-colonial times. The variable measuring economic growth is the complexity of large or impressive structures. The hypotheses are that 1) pathogen stress is negatively correlated to the presence of complex buildings, and 2) pathogen stress is positively correlated to increased ethnic diversity. The results support both hypotheses, and there are additional results, like 1) the negative correlation between pathogen stress and current income per capita and 2) the negative correlation between the increased ethnic diversity and current income per capita. Overall, this article shows the robust relationship between disease and economic development.

This study relates the type of games present in a society to the level of cultural complexity. Authors use a "game-type combination scale" that categorizes societies as having: 1) games of physical skill only; 2) games of physical skill and games of chance; and 3) games of physical skill, games of chance, and games of strategy. Results show a relationship between the game-type combination scale and indicators of cultural complexity.
