Lateral asymmetry in finger localization for right-handed, kindergarten girls

Laterality in finger localization (FL) was examined in 49 right-handed, kindergarten girls also administered tasks assessing verbal-receptive ability and manual dexterity. A right-hand advantage was evident overall and varied by FL task. The magnitude of asymmetry in FL was not unequivocally related to task requirement for verbal processing and was otherwise independent of children's verbal-receptive ability and motor laterality. The results were discussed in terms of cortical maturation and emergent cognitive-verbal processes as factors to be considered in the interpretation of asymmetry in FL.
