This paper presents research on the factors that promote romantic love as a basis for marriage in non-industrial societies. After a discussion of the previous literature on romantic love in ethnographic societies, the authors used the SCCS, EA, and data from eHRAF to create a data set of 109 cultures and then utilized multiple ordinal regression to test the relationship between different types of families and post-marital residence practices and the importance of romantic love in marriage. The findings show that monogamy is significantly correlated with romantic love, while nuclear family organization and neolocal post-marital residence are not significantly correlated. The presence of polygyny is found to lower the probability of romantic love being a basis for marriage. These findings contradict previous research, which found a relationship between non-neolocal post-marital residence and the presence of romantic love in marriage.

This study negates the hypothesis that romantic love is unique to Euro-American culture and provides evidence of romantic love in the majority of cultures sampled.

In asking whether or not there are meaningful universals in music, researchers compiled two catalogs – the Natural History of Song (NHS) Ethnography which contains ethnographic descriptions of song performances collected from eHRAF World Cultures, and the NHS Discography, which contains field recordings of performances of dance, healing, love, and lullaby. Using these two corpora, the study tests a variety of hypotheses about the universality and variability of both music behavior and music form. Specifically, whether there are meaningful universals in meaning and sound. The catalog of published sound recordings was analyzed by machine summaries, listener ratings, and manual transcriptions, which revealed that there were identifiable features of songs which could then predict their primary function cross-culturally. The results as a whole revealed that the existence of music is a cultural universal, and that the variation within music can be characterized by three factors assessing the formality, arousal, and religiosity of the song events. They also found that musical behavior varies more within societies than between them.

Previous cross-cultural studies of romantic love have, in the authors' view, been plagued by vague definitions of the concept and a conflation of cultural, bio-psychological, and social factors. Thus, the authors distinguish between the social aspect of romantic love (which they argue is a universal human predisposition) and the variable cultural valuation of romance. In a large cross-cultural sample, the authors test the hypotheses that gender equality and family organization are important predictors of the cultural valuation of romantic love.

This paper examines three measures of cultural complexity: Naroll’s (1956) social development index, Freeman’s (1957) Guttman scale of folk-urbanism, and Carneiro and Tobias’ (1963) Guttman scale of cultural complexity. The authors find significant associations between these three measures, suggesting that their strong validity. When used together, these measures account for a culture’s urbanization, organizational ramification, occupational specialization, and cumulative informational content of culture.

This study explores the relationship between property ownership, pair bonding, and sex as predictors of romantic jealousy. The results of an unpublished cross-cultural study are presented in support of the theory.

In this article, the author seeks to correlate interpersonal values with attitudes toward private property. After giving a brief intellectual history on the philosophy of private property, the author draws data from the Multinational Student Survey (MSS) in order to discern attitudes towards private property and preferences for one of six psychological constructs (Support, Conformity, Recognition, Independence, Benevolence, Leadership) which were outlined in the Survey of Interpersonal Values which was itself incorporated in the aforementioned MSS. These measures were then edited in order to be correlated and the reliability of each was verified. The strongest correlations that resulted were for dominance and nonconformity. The author concludes without a theory of how to reckon with these seemingly paradoxical results.

In this article researchers created a model to answer the question "What is a typical human life history of foraging skill?" While the immediate goal of this study was to create a model focused on age and relative skill, the larger purpose was to draw more clarity around the trajectory of human foraging skill over time. Researchers used data on hunting returns from 40 different study sites from around the world (Table 1) in order to assess the success of an expedition. While the model created here does not draw conclusions as to the absolute levels of production within or between societies, it can inform cross-cultural comparisons of relative skill at different stages of life. In conclusion, researchers found that the average hunter peaks at 33 years old, and by age 18, has 89% maximum skill (with the range of maximum skill being from ages 24-25). This skill was also found to decline slowly, such that it falls below 89% maximum after age 56. In terms of cross-cultural findings, the model found that cross-cultural variation is evident in the rate at which hunters develop peak skill, (meaning that within sites, the rate at which hunters develop skill is relatively homogeneous compared to the variation that distinguishes young hunters in different study sites), and individual hunters develop physical and cognitive abilities in concert, resulting in high hunting success by their late 20s and early 30s. In order to run the model, this study used the Hamiltonian Monte Carlo algorithm (in the Rstan package) for the sampling, and a Cobb-Douglas production function to express the observable foraging returns.

This study examines the relationship between satisfaction of early oral and dependence needs and concern with affection in adulthood. Data showed significant support for an association between the satisfaction of early oral needs (but not the satisfaction of dependence needs) and concern for affection in adulthood.

This study looks at the possibility of a universal system of social valuation by examining the correlation between shame and devaluation. Researchers conducted an experiment among 899 participants from 15 communities of high cultural variation in order to test if similar relationships between shame and devaluation exist independently of cultural contact or cultural evolution. The findings reveal that shame and devaluation are closely linked both between individuals and members of a local audience, as well as cross-culturally.
