  1. "In societies where infants' heads/limbs were repeatedly molded or stretched, where ears, noses or lips were pierced, where they were circumcised, vaccinated, innoculated or scarred with tribal marks, mean adult stature was over two inches greater" (1018)Landauer, Thomas K. - Infantile stimulation and adult stature of human males, 1964 - 4 Variables

    In previous studies, researchers have observed an increased growth rate in rats that experienced stimulation during infancy. This study examines the relationship between stressful experiences during infancy and adult male stature in humans cross-culturally. Results suggest a strong positive relationship between infant stress and adult male stature.

  2. The effect of one physical stressor will not differ significantly from the effect of two or more combined stressors (360).Landauer, Thomas K. - Correlates and consequences of stress in infancy, 1981 - 2 Variables

    This study is a continuation of previous research on the relationship between stress during infancy and adult height. With a better understanding of the stressors that infants experience and their effects, the authors test whether the relationship between stress and adult height remains significant when accounting for other environmental factors that may influence adult height. Results suggest that the relationship between infant stress and adult height does remain significant. Findings also show a relationship between infant stress and age at menarche.

  3. The presence of milking herds will be associated with increased male and female stature (446).Gray, J. Patrick - Height and sexual dimorphism of stature among human societies, 1980 - 2 Variables

    This article explores the relationship between sexual dimorphism of stature and variables of marriage, diet, subsistence and environment. Significant associations were found between security and plentifulness of food supply, protein availability, and sexual dimorphism of stature.

  5. Rate of exogamy will be negatively associated with community size. (1807)Dow, Gregory K. - The economics of exogamous marriage in small‐scale societies, 2016 - 10 Variables

    The authors develop and empirically test a model in which exogamy is negatively predicted by community size, due to decreasing heterogeneity from endogenous marriages in small settlements, and positively predicted by disparity in productivity between communities which is 'smoothed out' by transfer of community members through exogamous marriages. Support for both predictions is found, which is used to argue that cultural traits like marriage customs are heavily influenced by population-environment relationships.

  6. Adult male height will be greater in societies that increase protein for boys at puberty than those that do not (240).Whiting, Marjorie Grant - A Cross-Cultural Nutrition Survey of 118 Societies, Representing the Major C..., 1958 - 2 Variables

    Dietary variation has been implicated in population-level heath outcomes such as adult height and infant health. Here the author investigates these relationships in a sample of 118 nonindustrial societies, providing a comparative and quantitative assessment of nutrition and health cross-culturally.

  8. Rate of exogamy will be positively associated with disparities in productivity between the two residence sites. (1807)Dow, Gregory K. - The economics of exogamous marriage in small‐scale societies, 2016 - 12 Variables

    The authors develop and empirically test a model in which exogamy is negatively predicted by community size, due to decreasing heterogeneity from endogenous marriages in small settlements, and positively predicted by disparity in productivity between communities which is 'smoothed out' by transfer of community members through exogamous marriages. Support for both predictions is found, which is used to argue that cultural traits like marriage customs are heavily influenced by population-environment relationships.
