 This paper attempts to show that the use of a speech processing model is effective in analyzing and understanding speech disorder in aphasic patients. First, the author examined the influence of semantic and phonemic processes in the observed perseverative responses. Perseveration was found to be caused by the involvement of several processes including at the semantic and phonemic levels. The incidence of perseveration was decreased by intervening at the impaired levels of speech processing. Next, the author examined the semantic and phonemic priming effects on a naming task. The priming effects changed both correct response rate and error response rate. By analyzing the error responses, we were able to specify which processes had been impaired and different types of priming effect were observed for each aphasia patient due to the difference in the impaired processes.

 We therefore conclude that the use of a speech processing model should be recommended for assessing which processes are impaired to what extent, and for planning appropriate means of intervention.
