  1. 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.

  2. Controlling for genetics, climate, and nutrition, infant stress will be significantly related to adult male height (361).Landauer, Thomas K. - Correlates and consequences of stress in infancy, 1981 - 5 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. "[When] we . . . correlated menarcheal age with the Landauer-Whiting measure of infant stress . . . pain and shaping did show a positive association" (226)Whiting, John W.M. - Menarcheal age and infant stress in humans, 1965 - 3 Variables

    This study examines the relationship between infant stress and early menarche. Empirical analysis suggests that stress in infancy, such as mother-infant separation and head-shaping, are associated with early menarche.

  4. "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.

  5. Menarcheal age was negatively related to infant cold stress and infant internal stress (227)Whiting, John W.M. - Menarcheal age and infant stress in humans, 1965 - 3 Variables

    This study examines the relationship between infant stress and early menarche. Empirical analysis suggests that stress in infancy, such as mother-infant separation and head-shaping, are associated with early menarche.

  6. "The association between menarcheal age and the Gunders mother separation scores . . . [indicates] that this type of stress also leads to early menarche" (228)Whiting, John W.M. - Menarcheal age and infant stress in humans, 1965 - 2 Variables

    This study examines the relationship between infant stress and early menarche. Empirical analysis suggests that stress in infancy, such as mother-infant separation and head-shaping, are associated with early menarche.

  7. In infancy the mother is most likely to be the principal caretaker (170).Weisner, Thomas S. - My brother's keeper: child and sibling caretaking [and comments and reply], 1977 - 1 Variables

    This study discusses childcare done by children. While no empirical hypotheses are tested, the authors identify some potential sociocultural and developmental correlates of childcare by children and provide relevant descriptive statistics. Possible correlates include mother-child relationships, conceptions and emergence of childhood stages, organization of play groups, development of social responsibility, sex differences, personality development, cognitive style and cognitive development, motivation and learning.

  8. In infancy principal caretakers (other than the mother) are most likely to be female children or female adults (170).Weisner, Thomas S. - My brother's keeper: child and sibling caretaking [and comments and reply], 1977 - 1 Variables

  9. The acoustic properties of a song are positively correlated to behavior contexts cross-culturally.Mehr, Samuel A. - Universality and diversity in human song, 2019 - 2 Variables

    In asking whether or not there are meaningful universals in music, researchers compiled two catalogs – the Natural History of Song (NHS) Ethnography which contains ethnographic descriptions of song performances collected from eHRAF World Cultures, and the NHS Discography, which contains field recordings of performances of dance, healing, love, and lullaby. Using these two corpora, the study tests a variety of hypotheses about the universality and variability of both music behavior and music form. Specifically, whether there are meaningful universals in meaning and sound. The catalog of published sound recordings was analyzed by machine summaries, listener ratings, and manual transcriptions, which revealed that there were identifiable features of songs which could then predict their primary function cross-culturally. The results as a whole revealed that the existence of music is a cultural universal, and that the variation within music can be characterized by three factors assessing the formality, arousal, and religiosity of the song events. They also found that musical behavior varies more within societies than between them.

  10. Competitive games will be negatively associated with physical contact and comfort in infant socialization (37).Schlegel, Alice - Adolescents at play: a cross-cultural study of adolescent games, 1989 - 4 Variables

    This chapter investigates correlates of competitive adolescent games, focusing on societal and family characteristics as well as socialization variables and personality traits. Data suggest that games meant to encourage competitiveness will be more common for boys than for girls. Competitive games are also statistically associated with low societal and technological complexity, small and monogamous family organization, less physical contact and comfort in infant socialization, less integration in adult activities, and various personality traits.
