  • Title: Behavioral development of infant holding and its laterality in relation to mothers' handedness and child-care attitude.
    Author: Negayama K, Kawai M, Yamamoto H, Tomiwa K, Sakakihara Y, Japan Children's Study Group.
    Journal: Infant Behav Dev; 2010 Feb; 33(1):68-78. PubMed ID: 20036778.
    Abstract:
    The holding of 465 Japanese infants by their mothers was longitudinally observed at 4 and 9 months with several checkups and questionnaires of physical and psychological development and child-care attitude in a larger longitudinal study of mother-child relationships. A left side bias in holding was significant for the 4-month-old infants. The infants' increased autonomy in their ability to adopt a posture at 9 months weakened the holding bias. The mothers' handedness was related to different right/left hand contact patterns, but it was significant only for holding on the left side. The infants' reflexes relating to posture did not correlate with the holding bias at 4 months. The meaning and possible determinants of holding laterality are discussed.
