This study follows the theoretical construct of general cultural tightness and looseness (TL). Tightness is thought to be adaptive when facing socioecological threat, such as resource stress, since it involves a greater amount of cooperation. The study asks: "Why do some societies have relatively standardized or uniform clothing and adornment, whereas others have considerable variability across individuals?", which is connected to the broader question of why some societies show more within-group variation. The authors use a sample of 80 non-industrial societies from SCSS, to explore the relationship between general cultural tightness and standardization or synchrony in dress. The results support that tighter societies have more uniformity in dress and that resource stress is a predictor of synchrony. However, it is not supported that egalitarian societies have more synchrony, and that tightness is positively predicted by resource stress.

In this study, the authors analyze subsistence economies to better understand their variability and success, the role of the environment in different subsistence choices, and the relevance of fishing, specifically in mixed economies. They find regular subsistence patterns, suggesting that not all subsistence combinations are successful. Their findings also indicate that environment influences subsistence choice, mixed economies are common, and that fishing plays a key role in mixed economies.

In this article, the authors seek to test the theory that the veiling of women is a form of male mate guarding strategy, especially in harsh environments (specifically those with poor health and high mortality). They test this hypothesis using survey data drawn from 25 majority Muslim countries. This theory found support in the results of their statistical tests. In addition to testing the hypotheses articulated in the paper (as noted above), they also ran correlations between income level, importance of religion, and a countries sex ratio and views on the importance of veiling.

This study sampled over 4,012 language varieties, comparing their version of 40 generally universal words, such as body parts, water, the sun, pronouns, and common behaviors or animals. These language variations were tested in their association to "specific humidity," the variable used to represent ambient humidity of a language location. Results suggest negative association between the dryness of climate and the utilization of vowels, consitent with the idea that dry air affects the behavior of the larynx.

This study attempts to expand on the list of common customs employed to cope with childlessness in a marriage. Authors specifically examine the relationship between the presence of customs that help cope with childlessness and the severity of punishment for adultery. Results indicate a significant relationship between these two variables.

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.

This study demonstrates a correlation in Australian Aborigines between clothing and climate. Using an ethnohistorical approach, the author tests hypotheses that indicate the use of clothing as a behavioral response to environmental factors.

This study examines pairwise differences between similar cultures in order to minimize cultural variation within the SCCS and reveal possible correlates of cultural complexity. Results suggest that one measure of complexity (government above the community level) is significantly associated with several other variables.

Using cross-cultural comparative approaches among 249 cultures, this study explores the uniformity in human preference to concealing mating to others. The research questions guiding this study are: 1) Is the preference to conceal in legitimate mating a 'human universal'? and 2). What evolutionary pressures have originated this uniformity? The author proposes the ‘cooperation maintenance hypothesis’, which is built from three premises: sensory stimuli evoke sexual arousal in witnesses, humans are trying to exert control over their mating partner(s), and there is a need to foster within-group cooperation. This hypothesis suggests that concealing mating serves as a behavioral strategy to simultaneously retain control over mating partner(s) and foster cooperation with others. The author states that more analysis is needed to explain this behavior in other non-human species. The findings show support for the widespread pattern of concealment or attempts at concealment.

This study presents a psychological theory for adolescent initiation ceremonies. Findings support the hypothesis that initiation is a mechanism for maintaining continuity between the stages of childhood and adulthood, when the body is physiologically in discontinuity.
