This study uses empirical analysis to parse out different dimensions of permissiveness in child-rearing. Oral-sexuality, independence-anality, and aggression are the dimensions identified.

The main premise of the present study is to investigate the relationship between monotheism and dependence nurturance during early childhood and adulthood. Terry notes the human need to explain and understand the world, and theorizes that this understanding derives from personal experience, learned information, and supernatural explanation. Terry tests the hypothesis that supernatural explanations (monothestic beliefs) will be formulated if individuals cannot depend on their own experiences and/or others to reduce uncertainty (a result of independence training).

In this article the researcher conducted five different studies on in-group or "we-group" vs out-group or "they-group" discrimination practices. Two previous hypotheses are re-examined, the pathogen stress hypothesis and the rice-wheat hypothesis, in order to explain heightened ingroup-outgroup differentiation, before turning to overarching geographical hypothesis. Each of the five studies look at a different group of societies cross-culturally, ending in an index of intergroup discrimination by individuals across 222 countries in study 5. All five studies conclude that differentiation between us and them varies based on geographical location and more specifically, along latitude.

The study proposes a Bayesian modeling framework to analyze and examine the mapping between emotions and speech prosody. The models are fitted to a large collection of emotional prosody recordings, and the study reveals that the mapping varies across corpora, individuals, cultures, and sexes. The study suggests that models accounting for mapping differences across these factors outperform models assuming a global mapping.

This article explores the following questions: What environmental and cultural factors might explain variation in prejudice across cultures? Do these factors explain the intention to vote for nationalist politicians? The authors perform seven studies, focusing on the link between cultural tightness and the rise of prejudice in cultures. They theorize that cultural tightness is positively correlated with the rise of prejudice against people perceived as disrupting the social order. From this theory, they suggest three hypotheses: 1) cultural variation in tightness is related to cultural variation in prejudice, 2) cultural tightness is related to the support for nationalist politicians, and 3) cultural tightness is a link between ecological threats and prejudice. The results support these hypotheses, offering a cultural evolutionary perspective on prejudice.

This article uses alliance theory and kin selection theory to examine the relationship between consanguineous marriage and descent system. The author argues that there is no relationship between the severity of incest taboos and the rules of exogamy or endogamy. A series of testable hypotheses regarding incest, marital, and descent rules are presented.

This study focuses on cultural preferences for skin pigmentation. Findings indicate a general preference for lighter pigmentation in women. Cultural and biological theories are offered, and the authors suggest the skin-pigmentation preference is an instance of gene-culture coevolution. Areas for further research to explain the relationship of this finding with other features of society are suggested.

Controlling on a wide range of factors, this article examines the relationship between precolonial systems of leadership succession and contemporary deforestation rates. In a study of areas within the boundaries of 649 precolonial societies, the article finds that areas where local leaders were appointed by social standing were more likely to have poorer institutions governing forest management. The authors emphasize the importance of local governance over forest management and argue that precolonial institutions of leadership still have a bearing on current systems of forest management.

As the title suggests, the authors of this article investigate whether political repression motivates or deters anti-government violence. Through multinational analyses of 101 nationally representative samples from Africa, Asia, and Latin America, they find that highly politically repressed individuals are more likely to participate or have intentions to participate in anti-government violence.

This research examines how national culture influences the speed of COVID-19 spread in different countries. Three studies were conducted, and five national cultural dimensions were found to be significantly related to the speed of COVID-19 spread in the initial stages of the pandemic. These dimensions are power distance, uncertainty avoidance, humane orientation, in-group collectivism, and cultural tightness. The research found that COVID-19 spreads faster in countries with small power distance and strong uncertainty avoidance, low humane orientation and high in-group collectivism, and slower in countries with high cultural tightness.
