 We compared the performance on noun and verb picture naming tasks in two aphasia types. The subjects were 158 Broca's aphasics and 160 Wernicke's aphasics, and the results were analyzed in terms of the following four points : ① the degree of impairment for nouns and verbs for each of the aphasia types, ② the change over time in the difference between noun and verb impairment, ③ the types and frequencies of error responses in the "noun impaired group" and the "verb impaired group" of the two aphasia types, ④ the influence of verb types on the verb naming performance. Our results show that many of the Broca's aphasics showed greater impairment in verbs than nouns, while many of the Wernicke's aphasics showed greater impairment in nouns than verbs. The difference between noun and verb impairment did not change over time. Multiple comparisons of error patterns in the noun impaired and the verb impaired groups in each aphasia type showed significant differences between nouns and verbs. Therefore, it was thought that the production processes for nouns and the verbs exist independently of each other.
