The authors design and implement two tasks requiring linguistic and non-linguistic spatial reference across a linguistically-diverse sample in order to examine the relationship between language and cognition cross-culturally. The results, which indicate large conceptual variation in frame of spatial reference across as well as strong correlation between use of absolute descriptors and absolute cognitive representations within language communities, suggest that language structure may actively shape the systems of spatial representation available to different cultural groups.

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.

By analyzing patterns of between- and within-population musical variability among 16 Austronesian-speaking aboriginal groups, the researchers hope to evaluate degree of similarity to structures of human genetic diversity. As in the genetic domain, within-population variance is found to be much higher than between-population variance, leading the researchers to suggest that patterns of musical distance and divergence may serve as an indicator of cultural evolution.

The authors assess and compare preferred interpersonal distances over 42 countries. Environmental and sociopsychological factors are tested in order to explain variability in interpersonal distance across cultures. The authors seek to go beyond previous studies and better understand cultural differences and similarities in proxemic behaviors.

Divale seeks to explain the purpose of warfare that is characteristic of primitive societies by presenting the theory that such warfare is a population-control mechanism. Divale theorizes that among primitive societies, warfare exists in a "syndrome" that also involves female infanticide, blood-revenge, polygyny, and marriage alliances. Together, these features serve to control population growth, and are a necessary aspect of simple societies.

In the present study, Peregrine tests two perspectives regarding social resilience to climate-related disasters: 1) that societies with more inclusive and participatory political structures (corporate political strategies) are more resilient to climate-related disasters, and 2) that societies with tighter adherence to social norms are more resilient to climate-related disasters. Results support the notion that societies with greater political participation are more socially resilient to catastrophic climate-related disasters. Because these results are justifiably generalizable across multiple historical and cultural contexts, Peregrine's findings are a useful contribution to aid in disaster response policy decision making.

The authors contribute to a growing body of theory which posits cultural differences as a result of variable pathogen prevalence by testing the relationship between pathogen richness and various measures of conformity in a cross-regional sample. After controlling for confounds such as life expectancy, GDP, population density, arable land area, and agricultural labor force, the authors suggest that conformity is emphasized to varying degrees in response to the increased vulnerability to pathogens generally associated with deviation from normative social conduct.

The purpose of the present study is to provide insight on the debate concerning how best to organize societies: with more freedom (looseness) or with more constraint (tightness). In a comparison of 32 nations, Harrington, Boski, and Gelfand examine the relationship between tightness/looseness and three dimensions of societal well-being: psychosocial, health, and political/economic outcomes. Findings indicate that excessive constraint and/or freedom contribute to poorer psychosocial, health, and economic/political outcomes, as well as overall national-level well-being. These results suggest that a balance of freedom and constraint is associated with optimal societal well-being.

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.

This paper poses and tests relationships between local spatial variability of rainfall and property rights, as well as the degree of hierarchy, across 41 different tribal societies in Sudan. The authors find that there is a significant negative relationship between rainfall variability and degree of hierarchy. They also find that in the presence of local rainfall variability in Sudan, members of a tribe are more likely to establish common property institutions that allow access to all members.
