Repetitive Psychometric Measures: Handedness and Performance

Abstract

Many investigators have reported that right-handed people perform most motor tasks better, faster, and with relatively fewer errors than do the left-handed. We found slight differences in performance on only three of the tests of the Repetitive Psychometric Measures battery—SO, SC, and FC. Some of the difference in performance may be alleviated by minor changes in instruction for left-handed Ss.
