Neuropsychological Implications of Hand Preference versus Hand Grip Performance

Abstract

Hand-grip strength, measured by a hand dynamometer, was compared with hand preference for writing in a sample of 173 male and female undergraduate students. Hand preference and performance correlated significantly, but superiority of hand grip for 24% of the subjects did not coincide with the preferred hand. Hand-grip performance was not an accurate predictor of hand preference, and neuropsychological inferences on the basis of hand performance should be made cautiously. No significant differences were found between the right/left ratio scores for males and females, or order conditions.
