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 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 challenges the Big Gods hypothesis, which suggests that moral gods are a critical factor that preceded the evolution of complex societies. Using the Seshat database, the authors expanded the codebook and database of their retracted article (see notes). The results show significant support that sociopolitical complexity and moralizing gods are associated and that sociopolitical complexity appears to precede the presence of Big Gods. The authors also show some support that sociopolitical complexity might be a driving factor of moralizing gods. Still, they state that the results are incomplete since they only focus on the possibility of reciprocal causality.

Researchers tackle the moral gods hypothesis which proposes that moral gods enabled large-scale societies to evolve. They use 414 societies spanning 10,000 years in Seshat: Global History Databank and code 51 measures of social complexity and four measures of moral gods. The findings of the present study challenge the moral gods hypothesis. In the societies studied, complex societies appear to precede moral gods rather than the inverse of moral gods preceding complex societies.

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).
