This study used data from the Afrobarometer Survey to compare the cultures of 85 ethnolinguistic groups from 25 African countries on markers of cultural modernization and emancipation, such as attitudes towards gender equality, xenophobia, and the role of religion in society. The study found that nearly all of the ethnolinguistic groups studied within a country clustered together in terms of their attitudes towards cultural modernization. The study also found that the variation between nations was often greater than the variation between ethnolinguistic groups, and that the cultural differences between ethnolinguistic groups within a nation were highly correlated with economic indicators such as GDP per person, employment in agriculture and the service sector, and phone subscriptions per person. The study suggests that economic development and modernization lead to cultural homogenization within a nation and a decreasing relevance of ethnolinguistic culture.

This article offers a detailed analysis of neuropsychopsiological processes involved in altered states of consciousness (ASC) in order to design and evaluate a psychophysiological model of trance states. Cross-cultural hypotheses concerning ASC are tested.

Using a sample of 313 societies classified within 24 language phyla, authors put forward a statistical model based on climate data [specifically focused on the 10°C (50°F) winter temperature isotherm] to explain why dispersion of preindustrial language phyla is remarkably homogeneous even despite heterogeneous geographical dispersion of sampled preindustrial cultural groups. They suggest that temperature has been a barrier to migration.

Genetic, linguistic, and geographic data can be used to explain the distribution of cultural units ("semes") and to understand the evolutionary mechanisms of culture. Three broad models of cultural transmission attempt to explain why cultures share semes: (1) Cultural diffusion, emphasizing horizontal transmission. (2) Local adaptation, where trail-and-error learning leads to the independent adoption of semes by different peoples living in similar environments. (3) Demic diffusion, which emphasizes vertical and frequency-dependent transmission. Authors test the explanatory power of each model using cultural, genetic, linguistic and geographic data from 36 African cultures.

This study examines correlates of age-grading and generations, particularly bachelor promiscuity, in order to test the matched-pairs method of cross-cultural analysis. The authors suggest that their test is not a completely adequate measure of the matched-pairs method, but is merely a trial for using experimental and control groups in a cross-cultural study.

The authors test the relationship between ethnolinguistic area and various environmental variables in a cross-cultural sample of hunter-gatherer, pastoral, and agricultural subsistence groups in order to evaluate various hypotheses surrounding the geographic and ecological origins of cultural diversity. They propose that societies which adopted agriculture at the beginning of the Holocene were less directly affected by climate which, combined with the effect of increasing political and cultural complexity, allowed coordination and homogenization of ethnolinguistic groups over a broader swathe of territory.

The authors examine musical diversity in India using cantometric data from 32 Indian societies with the goal of better understanding how music varies between and within cultures. They find very minor musical differences between language families, greater diversity between societies but within language families, and the most variation within societies.
