Abstract
Asymmetry of hand performance was investigated with the paper-and-pencil test of hand dominance originally developed by Steingruber in 1971. This test, originally constructed to measure asymmetry of hand performance in children, gave appropriate scores on asymmetry of hand performance in adults if a shorter time limit than originally proposed was applied. Asymmetry of hand performance in adults as measured with the new instruction showed reliable asymmetries in performance which are similar to those obtained on different widely accepted tests measuring asymmetries of hand performance.
