The Relationship Between Aphasia and Visual Agnosia

Abstract

Visual recognition of pictorial material was investigated in a group of 76 patients with localized cerebral lesions. The aphasics as a group were most impaired in visual recognition, more than nonaphasic patients with left or right hemispheric lesions. It could be demonstrated that beside aphasia intellectual functioning and visual discrimination performance make significant contributions to visual recognition performance. Most of the divergent results in the literature on visual recognition performance in brain-damaged subjects could be reconciled with these three factors.
