Picture confrontation oral naming: performance differences between aphasics and normals.
Oral confrontation naming was compared in 108 normal subjects controlled for education, age, and gender and in 18 aphasic patients for the same set of 115 pictures. Demographic variables influenced both normals' and aphasics' performance. However, the nature of aphasics' misnamings on the one hand and the differential effects of characteristics of pictures and words on normals' and aphasics' responses on the other indicated specific deficits in patients. The classical hypothesis that aphasics' misnamings and the production of word associations by normals should rely on similar mechanisms (Rinnert & Whitaker, 1973) is questioned. Nondominant responses observed in normals accounted for a larger proportion of verbal errors than associates to target words.
