Abstract One theoretical cause of phonemic paraphasias in conduction aphasia is the instability of phonological representations stored and then reactivated in the second stage of speech production. Based on this, we used a "letter-manipulating therapy" with two aphasic patients, in which they form representations externally following the speech production model.
As a result of this therapy, the conduction aphasic patient produced fewer phonemic paraphasias, with possible generalization to observed post-therapy improvement in non-word repetition, an issue not specifically targeted by this therapy. The Wernicke's aphasic patient, however, does not improve as much. Why this therapy is more effective for conduction aphasia than Wernicke's aphasia is discussed in light of their speech production deficits, as are the implications for the speech therapy for aphasics.
Keywords conduction aphasia, phonemic paraphasia, speech production, phonological representation, speech therapy for aphasics
