Dichaptic task performance as a function of ability pattern, sex, and hand preference.
It was hypothesized that, since verbal and spatial ability seem to be lateralized (left for verbal, right for spatial), in any dichaptic task individuals with high spatial ability will do best with their left hands and those with high verbal ability best with their right hands. Conversely, scores with high spatial ability should make more errors with their right hands and highly verbal people more errors with their left hands. Some evidence was found to support these hypotheses for males, but for females the relationships seemed more complex. Possible explanations and implications of the findings are discussed.
