The direction of drawing a circle, labeled the ‘torque test’ (Blau, 1977), was evaluated in 74 normal adults (age 14 to 44 yr.) as a predictor of both handedness and cerebral dominance on the dichotic listening test. The results indicate that torque is related to handedness but not to lateralization of language. We suggest that circle-drawing by adults is dependent more on the muscle mechanics of the hand than on cerebral dominance.
