Visuoperceptual and visuomotor abilities and locus of lesion.
Possible differential effects of laterality and caudality of cerebral lesions on simple visuoperceptual and visuomotor skills were examined. As expected, the right hemisphere lesion group was significantly more impaired than the left hemisphere lesion group. The effects of the caudality of lesion, however, yielded interesting results. While the right posterior group was worse than the right anterior lesion group, as expected, the left posterior lesion group was better than the left anterior lesion group. Our findings points to a possibility that the left hemisphere, especially the anterior region, might not be as silent in processing simple visual stimuli as has been accepted.
