  1. 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.

  2. 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.

  3. 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.

  4. A Cross-Cultural Nutrition Survey of 118 Societies, Representing the Major Cultural and Geographic Areas of the WorldWhiting, Marjorie Grant - , 1958 - 22 Hypotheses

    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.

  5. Infant socialization and games of chanceBarry III, Herbert - Ethnology, 1972 - 14 Hypotheses

    This paper explores the relationship between games of chance and various aspects of infant socialization, as well as subsistence economy and social organization. Several significant associations were found between these variables.

  6. Correlates of monogamy in human groups: tests of some sociobiological hypothesesGray, J. Patrick - Behavior Science Research, 1984 - 7 Hypotheses

    This study re-examines the hypotheses offered by Kleiman (1977) linking monogamy in humans to monogamy in other animals. Of seven hypotheses, only two were weakly supported when using a cross-cultural analysis.

  7. Human milk immune factors, maternal nutritional status, and infant sex: The INSPIRE studyCaffé, Beatrice - American Journal of Human Biology, 2023 - 1 Hypotheses

    The Trivers-Willard hypothesis posits that concentrations of human milk immune factors vary with maternal condition (maternal diet diversity and body mass index) and the sex of the infant. Using linear mixed-effects models to analyze 358 milk samples from 10 international sites, the authors find minimal support for the Trivers-Willard hypothesis; only one immune factor, IgG, exhibited a significant relationship.

  8. 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.

  9. The couvade: a psychological analysisMunroe, Robert L. - Ethos, 1973 - 1 Hypotheses

    This study examines possible correlates of the couvade. Results suggest that matri-residence, mother-infant sleeping arrangements, and low male salience all are associated with the couvade.

  10. Winter temperature as a constraint to the migration of preindustrial peoplesWhiting, John W.M. - American Anthropological Association, 1982 - 4 Hypotheses

    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.
