[Hand Preference: Cognitive Development, Asymmetry, and Consistency.]
Bathurst, Kay; And Others
Reported are results of three studies: (1) Hand Preference Consistency during Infancy and Preschool Years (K. Bathurst and A. W. Gottfried), (2) Asymmetry of Verbal Processing: Influence of Family Handedness (K. Bathurst and D. W. Kee), (3) Consistency of Hand Preference and Cognitive Development in Young Children (K. Bathurst and A. W. Gottfried). Consonant with proportions previously reported for older children and adults, results of the first study reveal a high degree in consistency of hand preference from infancy through the preschool years. Findings imply that the establishment of hand preference may emerge earlier than is currently believed and favor the theoretical view of developmental invariance in functional asymmetry. Results of the second study suggest that, when compard on a measure involving verbal processing, dextral family members show more left hemisphere asymmetry and sinistral family members are more bilateralized. Based on the behavior of 89 children who were either consistent or nonconsistent in hand preference at 18, 24, 30, 36, and 42 months of age, results of the third study indicate that cross-time consistency in drawing hand preference is significantly and pervasively related to intellectual performance for females but not for males.
