Left-Cerebral Hemisphere Superiority in Tachistoscopic Word-Recognition Performances

Abstract

Under conditions of monocular unihemispheric projection of word stimuli to the brain, 10 normal Ss uniformly showed superior word recognition ability of the left, as opposed to the right, cerebral hemisphere. Left-hemisphere recognitions were significantly more frequent than right-hemisphere recognitions for both eyes, but the extent of left-hemisphere superiority was significantly greater for the left eye. The results support the hypothesis that words projected to the right hemisphere traverse a less efficient route to the language centers of the left hemisphere.
