Hemispheric superiorities on a unilateral tactile test: relationship to cognitive dimensions.
Subjects, 30 male and 30 female, were administered a unilateral tactile test, which requires the subject to judge line orientations. More field-independent individuals in the sample perceived line orientation significantly more accurately with their left hand than with their right hand, while more field-dependent individuals showed no significant lateral difference. However, a similar pattern was observed when a verbal comprehension measure was used as a criterion. The results are discussed as they relate to the hypothesis of a link between psychological differentiation and cerebral specialization.
