Abstract
The study of illiterate subjects with brain lesions is a good model to understand the cultural variable for cerebral functional organization. The question of aphasia in this population is reviewed in this chapter. There are problems concerned with the test material used, which has to be adapted for illiterate subjects: visual naming, for instance, has to be tested with real objects and not with line drawings of the objects. However, when aphasia is considered there are not important differences, between illiterate and literate subjects, on what concerns the cardinal symptoms which allow a clinical diagnosis of aphasia type. Some non-verbal defects, like constructional apraxia, may, however, reflect differences.KeywordsStroke SubjectLiterate SubjectLeft Hemisphere LesionColored Progressive MatriceOral ComprehensionThese keywords were added by machine and not by the authors.
