The researchers utilize a GIS approach in order to examine the relationship between global linguistic distribution and various cultural and environmental factors. The resulting positive association between political complexity and both latitude and language range leads the researchers to propose that large, politically complex entities exert a homogenizing pressure on language. However, the causal link may also be in the other direction, with possession of common language facilitating the creation of more complex political institutions.

This article explores biological, psychological, and social explanations for menstrual taboos. Attention is paid to the role of men in rituals associated with reproduction--i.e. before, during and after childbirth, as well as during girls' puberty rites.

While not mechanically related, the transmission of genes and the transmission of languages are both mediated by culture. For example, in societies where marriage outside the language group is common, matrilocal residence practices may result in the preferential conservation of the mother’s language(s), as well as the development of distinct mtDNA haplogroups throughout a region. In this study, the authors use single nucleotide polymorphism (SNP) data from 130 culturally distinct populations to assess the correlation between genetic distance and linguistic distance, while controlling for various cultural and geographic factors (in other words: when populations are more genetically dissimilar, do they also tend to be further apart linguistically?). Results suggest that while the often-referenced idea of sex-based transmission of language is not universally predictable, linguistic distance almost always tends to correlate positively to both spatial and mitochondrial genetic variation.

This article investigates the relationship between economic type and socialization of children. The author focuses on the concentration of value emphases in childhood socialization--that is, whether children are instilled with several different value orientations rather than just one or two. Value concentration is examined alongside subsistence technology and economic diversification; attention is also paid to gender differences.

This study examines husband-wife relationships, specifically rooming and sleeping arrangements, as they relate to variables such as infant care, subsistence, residence, and cultural complexity. Several hypotheses are tested and all are supported.

This paper supports Beatrice B. Whiting's (1965) sex-identity conflict hypothesis which suggests a relationship between males' early identification with their mothers and male violence. Authors find that, in addition to socialization aggression, frequency of homicide/assault is significantly related to father-infant sleeping distance, particularly when residence is not matrilocal and/or warfare is more than occasional.

This study examines the explicitness of persuasion in cross-cultural communication using a corpus-based register analytical approach. The study compares 2518 speeches from 55 cultures in the East and West from 1970 to 2020 using Multi-Dimensional Analysis (MDA) to identify linguistic features related to persuasion. The results show significant differences between the East and West in terms of the overtness of persuasion, which is generally narrowing over time. The study suggests that political contexts may impact the cross-cultural gap in persuasion explicitness, and offers implications for further research on cultural styles of political persuasion.

In order to investigate cross-cultural variation in systems of conversational turn-taking (who speaks and when), the researchers analyze the association of various contextual, verbal, and non-verbal factors with mean response time. Despite some variation in response time between languages, each of the explanatory variables is found to have significant impact on response time independent of language. A further test on subjective perception of ideal response time suggests that although similar factors act on response patterns cross-culturally (in support of a 'universal systems' theory), speakers are hypersensitive to even minor cultural variations in response time.

This study posits that dowry is a recent historical development, and that cultural complexity is a necessary but not sufficient cause for its emergence. Comparisons of frequencies support these claims.

This paper is an investigation into the relationship between social differentiation as a proxy for societal 'development' and various categories of crime. A positive relationship is interpreted by the author as empirical cross-cultural support for Durkheim's theory that these two factors will increase together as parallel processes of 'sociocultural evolution'.
