Hemispheric specialization for tactile-spatial processing in preschool children.
Witelson (1976) found that boys but not girls showed right-hemisphere specialization for tactile-spatial processing as early as 6 yr. of age. In the present study, Witelson's task was administered to 46 normal 4- and 5-yr.-old girls and boys. Both sexes showed right-hemisphere specialization. There were no sex differences either in specialization or in over-all performance.
