Distributions of hand preference and hand skill asymmetry in preschool children: theoretical implications.
We describe the distributions of hand skill asymmetry for the Peg-moving task and the Graphic test among 765 preschool children. A single normal component was observed for the Peg-moving task, but two normal components for the Graphic test, which corresponded primarily to the right- and left-handed children. Hand Preference and Graphic test hand skill asymmetry were age-dependent, but there was no age effect on the PMT hand skill asymmetry. Results are discussed in relation to the Annett's Right Shift theory.
