This study deals with word retrieval problems of aphasic patients. This word-finding difficulty is a common characteristic of aphasics and many methods have been used by aphasia clinicians to attempt to remediate word retrieval skills. Cueing, one of the methods used, presumably facilitates word-finding by supplying additional information to the aphasic patient about the target word he is attempting to produce. This research attempts to measure the three types of cues on naming behavior of aphasics. Semantic, phonemic, and neutral verbal cues are studied to determine their effects on both accuracy and latency of aphasic subjects' naming responses. The results demonstrated clear individual differences in the way that the aphasics responded to the various types of cues. In general, phonemic cues proved to be the most effective in increasing response accuracy and decreasing response latency for these patients. Semantic cues, on the other hand, appeared to hinder communicative effectiveness as they decreased response accuracy and increased response latency when compared to neutral or phonemic cues. A review of the literature discusses several factors that influence performance on a naming task. (NCR)
