Abstract

Hand preference, eye preference, and the concordance of hand-eye preference were assessed in 99 healthy preschool-age children (46 boys: Mage= 55.4 mo., SD= 10.5 and 53 girls: Mage=53.6 mo., SD= 11.8). Children were also administered neuropsychological measures requiring attention and reaching to both sides of midline including the Peabody Picture Vocabulary Test, Third Edition, Multiple Boxes Test, Developmental Neuropsychological Assessment Visual Attention, and Imitating Hand Positions. All groups performed in the average range using standard administration and scoring of the neuropsychological tests, and no significant differences were found in performance between those with left- versus right-hand preference, left-versus right-eye preference, or concordant versus discordant hand/eye preference. In contrast, significant differences were noted in task approach to neuropsychological measures depending on hand preference. Rate of left-hand preference in this sample was consistent with that seen for adults; and rate of left-eye preference, and hand/eye concordance remained stable across age groups 3 to 6 years. While the presence of left-hand or -eye preference or discordance in the preschool years appears to be a benign characteristic in relation to standardized test performance, some aspects of test-taking efficiency may be affected.
