Abstract
The purpose of this paper is to report the examination of aphasics' responses on four word-finding tests. On the confrontation naming test and the category naming test, there were various types of semantic relationships between the targets and the error responses. Especially in the confrontation naming test, the most prevalent error response was that of another item belonging to the same semantic category as the targets. The types of other related responses were very diverse. On the two verbal fluency tests in semantic categories and in ‘ad hoc categories (e. g., “If your house should catch fire, what would you bring out?”)’, aphasics generated several words which were typical responses to that category as well as relatively rare responses. On the verbal fluency test in semantic categories, most of the typical responses of aphasics overlapped with those of normal subjects.
