 This study investigated the noun and verb retrieval ability of patients with aphasia and the factors that facilitate such retrieval. The participants were 5 patients with Broca's aphasia and 5 patients with Wernicke's aphasia, all caused by left-hemisphere stroke. They performed picture naming tasks for 90 nouns and 90 verbs, whose familiarity and imageability were matched. During the tasks, 2 types of cues were given, namely phonemic cues presenting the initial syllable of the target word and sentence cues presenting part of the sentence involving the target word. The effectiveness of the cues was compared. The results show that among Broca's aphasia patients there was no significant difference between the noun and verb naming scores, whereas the Wernicke's aphasia patients showed significantly better performance with verbs than nouns. In both aphasia groups, noun retrieval was facilitated more by phonemic cues than by sentence cues, whereas verb retrieval was facilitated more by sentence cues. Both types of cue were more effective in patients with higher word retrieval ability for nouns, but the sentence cues on verbs were not more effective in patients with higher word retrieval ability. These results suggested that the patterns of noun and verb naming deficits were different between the 2 types of aphasia and that the cues to facilitate verb and noun retrieval are different.
