Visual-motor organization and memory in the right-handed and the left-handed child: A comparative neuropsychological approach

Abstract

The visual-motor organization of the child was investigated with the primary aim of defining the relationships between the cognitive changes taking place during problem solving (mnemonic reproduction of a complex figure) and the structural functional elements involved. The sample consisted of 840 right-handed and left-handed children aged 5.5 to 12.5 years, who were group-matched on the basis of age, sex, and hand preference. Statistical evaluation revealed significant differences far boys and girls across the various age groups. Statistically significant differences also appeared between right- and left-handed children. The differences in performance can be attributed to neuropsychological functional differences between right- and left-handed children.
