Visual hemispheric asymmetry and right-left confusion.
From 357 university students two groups of 8 women each were selected, one group with high right-left confusion and the other without such confusion according to self-reports. Reaction times to stimuli tachistoscopically presented in visual hemifields were recorded to estimate the relationship between perceptual asymmetry and right-left confusion. A significant difference between hemifields and an interaction of hemifield by group appeared, whereas asymmetry in the highly confused group was not so related. According to a model of cerebral functioning in the formation of the body image, these results suggest subjects with high right-left confusion have greater hemispheric bilateralization.
