  1. Infantile stimulation and adult stature of human malesLandauer, Thomas K. - American Anthropologist, 1964 - 1 Hypotheses

    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. Correlates and consequences of stress in infancyLandauer, Thomas K. - Handbook of Cross-Cultural Human Development, 1981 - 3 Hypotheses

    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. Effects of climate on certain cultural practicesWhiting, John W.M. - Explorations in Cultural Anthropology: Essays in Honor of George Peter Murdock, 1964 - 5 Hypotheses

    This study explores ecological reasons that might explain why boys are mostly circumcised in tropical regions, particularly in Africa and the insular Pacific. The author postulates a long causal chain linking: 1) tropical climate to the growing of root and fruit crops; 2) the need to keep babies on mother's milk for as long as possible where the adult diet is lacking in protein; 3) a long post-partum sex taboo as a way to space births; 4) the practice of polygyny (and associated mother-child sleeping) in the face of a long sex taboo; 5) patrilocal residence; and 6) male initiation ceremonies which are believed to result from the combination of mother-child sleeping, the long poast-partum sex taboo and patrilocal residence.

  4. A cross-cultural investigation into the sexual dimorphism of statureWolfe, Linda D. - Sexual Dimorphism in Homo sapiens: A Question of Size, 1982 - 3 Hypotheses

    This article examines height and sexual dimorphism of stature from a sociobiological perspective. Diet, child rearing, and marriage practices are tested as possible factors contributing to height sexual dimorphism of stature. Results provide some support for a nutritional hypotheses, but sexual selection and parental investment are not statistically significant.

  5. The effects of mortality, subsistence, and ecology on human adult height and implicationsMigliano, Andrea Bamberg - Current Anthropology, 2012 - 1 Hypotheses

    By better understanding the factors influencing adult height in modern populations, the authors hope to generate a testable hypothesis to determine the factors affecting body size during hominin evolution. The authors employ an exploratory linear regression model to test the effects of mortality, environment, and subsistence strategy on adult height among traditional small scale human societies. They found that mortality rates were the most significant predictor of adult height and that people living in savanna environments are consistently taller.

  6. Parental rejection, food deprivation, and personality development: tests of alternative hypothesisRohner, Ronald P. - Ethnology, 1970 - 2 Hypotheses

    This article investigates potential relationships between food deprivation, parental rejection, and personality development. Findings indicate that a series of adult personality characteristics (e.g. self evaluation and emotional responsiveness) are better predicted by parental rejection than by nutritional variables.

  7. Mother-infant separation and physical growthGunders, Shulamith - Ethnology, 1968 - 1 Hypotheses

    This study examines the relationship between adult male height and mother-infant separation. Results indicate that males who are separated from their mothers briefly during infancy are taller in adulthood than those who are not.

  8. Cassava production and processing in a cross-cultural sample of african societiesRomanoff, Steven - Behavior Science Research, 1992 - 12 Hypotheses

    This exploratory study seeks to explain cassava production and processing in Africa by considering cultural, agronomic, and environmental data. After examining the descriptive results of the agricultural and social contexts of cassava use, the authors build upon Boserup's population density model (1965) to analyze their own hypothesized model of cassava's importance among the sampled societies.

  9. Female status, food security, and stature sexual dimorphism: Testing mate choice as a mechanism in human self-domesticationGleeson, Ben Thomas - American Journal of Physical Anthropology, 2018 - 1 Hypotheses

    The present study examines the effect of social status on stature sexual dimorphism and whether food security acts as a mediator for this relationship. In societies where females have high social status and can exercise mate choice, there is lower stature sexual dimorphism. Food security enhances these results. Conversely, there is greater stature sexual dimorphism in societies where females have low social status and cannot exercise mate choice, especially if there is food insecurity.

  10. Height and sexual dimorphism of stature among human societiesGray, J. Patrick - American Journal of Physical Anthropology, 1980 - 6 Hypotheses

    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.
