Asymmetry of Perception of Size between the Right and Left Hands in Normal Subjects

Abstract

A method of measuring the perception of size in the hands was applied to 4 0 right handed and 40 left-handed normal subjects. It was found that objects of equal size held simultaneously in each hand tend to be judged to be unequal, and that, in the majority of subjects, the object held in the dominant hand is perceived to be the smaller. These results are discussed in the light of previous work, and some reference is made to the examination of pathological cases.
