Research concerned with the relationships between the hemispheric locus of a cerebral hemisphere lesion and observable changes in psychological performance has been fairly consistent in finding a decrement in verbal ability associated with lesions in the dominant (left in right-handed patients) hemisphere.^{1,5,7,9,12,13,15} Although such findings are often helpful in clarifying the nature and extent of verbal impairment, they hardly represent a remarkable discovery for the neurologist, who has long been aware of the high correlation between damage to the dominant hemisphere and dysphasia.

Studies which have dealt with brain damage and its relationships to spatial or spatial-temporal tasks (where such tasks are distinguished by the perception of elements of a spatial configuration either simultaneously or successively over time) have not provided as clear a picture. Clinical studies of patients with lesions restricted to the right hemisphere have demonstrated that such lesions may be associated with spatial or spatial-temporal impairment. . . .
