Abstract
Aphasic patients were given tests assessing pantomime recognition, reading comprehension, aural comprehension, and naming ability to determine whether defective pantomime recognition could be the result of a disturbance of symbolic thinking also affecting linguistic functioning. Defects in pantomime recognition always occurred in conjunction with reading defects of at least comparable severity, but reading defects sometimes occurred without comparable defects in pantomime recognition. The relationship of pantomime recognition with both aural comprehension and naming ability was significantly weaker than that between pantomime recognition and reading comprehension. The implications of the findings with regard to other nonverbal aphasic symptoms and the role of sensory modality factors are discussed.
