The neuropsychological significance of lateral preference for complex visual activities in children with learning disabilities.
In the present study the relationship between neuropsychological functioning and lateral preference for visual activities was examined with learning disordered children. Specifically, the relationship between measures of the Lateral Dominance Exam (LDE), scores on the Halstead-Reitan Neuropsychological Battery (HRNB), and the Wechsler Intelligence Scale for Children-Revised (WISC-R) were explored. A canonical analysis suggested that composites of neuropsychological functioning and lateral preference shared 22% of variance. Learning disabled children with strong right or left preference for visually guided motor activities showed lower performance in spatial tasks on the ipsilateral side and in simple motor skills on the contralateral side. Children in the present study with strong right preference patterns for visually assisted motor activities also showed low performance on visual tracking tasks. These data offer some support for assessing lateral preference in learning disabled children.
