  1. The role of pre-mastication in the evolution of complementary feeding strategies: a bio-cultural analysisZhang, Yuanyuan - , 2007 - 1 Hypotheses

    This thesis uses a cross-cultural sample to examine the relationship between anemia and infant feeding practices. Examples from the ethnography are presented. Findings are largely descriptive on practice, but are largely inconclusive with regard to anemia.

  2. Contemporary parasite stress curvilinearly correaltes with outgorup trust: Cross-country evidence from 2005 to 2014Zhang, Jinguang - Evolution and Human Behavior, 2018 - 2 Hypotheses

    Using a sample of 80 countries and political regions, the present study examines the effect parasite stress has on people's trust towards ingroup and outgroup members. The findings do not offer support of there being a concave relationship between parasite stress and ingroup member trust. The results do indicate that there is a U-correlation between trusting outgroup members and parasite stress.

  3. Premastication: the second arm of infant and young child feeding for health and survival?Pelto, Gretel H. - Maternal and Child Nutrition, 2009 - 1 Hypotheses

    This study asserts that premastication (the pre-chewing of food for infant feeding) has existed as a cross cultural human universal stemming from the post natal immaturity of infant development and their need to have nutritional supplements to breast milk before they develop the molars necessary to consume an adult diet. Hypotheses are informally tested by sampling 119 cultures from the eHRAf database and looking for frequency of premastication occurrence. About one-third with information on infant feeding mention pre-mastication.

  4. A phylogenetic analysis of dispersal norms, descent and subsistence in Sino-TibetansJi, Ting - Evolution and Human Behavior, 2022 - 3 Hypotheses

    In this study, the authors analyze the evolutionary history of female and male marital dispersal norms in Sino-Tibetan ethnic groups. They also test for the coevolution of agriculture, domesticated cattle pastoralism, and unilineal descent with these dispersal norms. Results indicate that early Sino-Tibetans were likely patrilocal, agriculture and unilineal descent coevolved with female dispersal norms, and cattle domestication did not coevolve with dispersal norms in Sino-Tibetan ethnic groups.

  5. How National Culture Influences the Speed of COVID-19 Spread: Three Cross-Cultural StudiesHuang, Xiaoyu - Cross-Cultural Research, 2022 - 5 Hypotheses

    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.

  6. Residential variation among hunter-gatherersEmber, Carol R. - Behavior Science Research, 1975 - 7 Hypotheses

    This study explores predictors of variation in two dimensions of marital residence patterns among hunter-gatherers: 1) the tendency toward patrilocality versus matrilocality and 2) the tendency toward unilocality versus bilocality.

  7. Our better nature: Does resource stress predict beyond-household sharingEmber, Carol R. - Evolution and Human Behavior, 2018 - 3 Hypotheses

    The present research investigates food sharing and labor sharing practices of 98 nonindustrial societies. The aims are to: 1) document the frequency and scope of sharing, and 2) test the theory that greater sharing is adaptive in societies subject to more resource stress (including natural hazards).

  8. Disease and diversity in long-term economic developmentBirchenall, Javier A. - World Development, 2023 - 2 Hypotheses

    This article uses the Standard Cross-Cultural Samples to test the relationship between disease and economic growth among sub-Saharan African societies. The authors suggest that a higher disease prevalence limits social integration and economic development since pre-colonial times. The variable measuring economic growth is the complexity of large or impressive structures. The hypotheses are that 1) pathogen stress is negatively correlated to the presence of complex buildings, and 2) pathogen stress is positively correlated to increased ethnic diversity. The results support both hypotheses, and there are additional results, like 1) the negative correlation between pathogen stress and current income per capita and 2) the negative correlation between the increased ethnic diversity and current income per capita. Overall, this article shows the robust relationship between disease and economic development.

  9. Inculcated traits and game-type combinations: a cross-cultural viewRoberts, John M. - The Humanistic and Mental Health Aspects of Sports, Exercise and Recreation, 1976 - 1 Hypotheses

    This study relates the type of games present in a society to the level of cultural complexity. Authors use a "game-type combination scale" that categorizes societies as having: 1) games of physical skill only; 2) games of physical skill and games of chance; and 3) games of physical skill, games of chance, and games of strategy. Results show a relationship between the game-type combination scale and indicators of cultural complexity.

  10. Modernization as changes in cultural complexity: new cross-cultural measurementsDivale, William Tulio - Cross-Cultural Research, 2001 - 2 Hypotheses

    This article considers the consequences of modernization. Factor analysis is used to identify four stages of modernization: 1) changes in education, government, and trade; 2) changes in health, technology, and transportation; 3) changes in family, religion, and toilet; and 4) changes in behavior. The authors then consider five trends they expect to be associated with modernization and test whether they develop over the course of the four stages. Results indicate that these 5 trends—increased cultural complexity, female status, pacification, suicide, and social stress—are associated with only the first and fourth stages.
