ABSTRACT
The case of a reproduction conduction aphasic patient, R.L., is presented. R.L. produces phonemic paraphasias in single word repetition, reading aloud, and picture naming, which are qualitatively similar inasmuch as they are strongly influenced by the number of syllables in the word to be produced. R.L. makes similar errors in repeating nonwords, but his performance is more impaired than with words. This pattern is discussed in relationship to several theories of the abnormalities in single word production leading to phonemic paraphasias. The results are inconsistent with many models, and suggest that there is a common stage of abstract phonological representations that is accessed in repetition, reading, and naming. It is hypothesized that this abstract representation is an underlying phonological representation.
