| Abstract: | The speech of a patient with a mild impairment in phonological encoding or Reproduction Conduction Aphasia was investigated using a series of specially designed experimental tasks The patient committed phonemic paraphasias in all speech production tasks although these were somewhat less pronounced in repetition than other single word tasks On a task requiring the recital of word strings e g dam sauce tide goat knock meat night make his performance was found to be sensitive to rate of speech and size of anticipated planning unit Like normal controls he showed a strong lexical outcome effect and his anticipations outnumbered perseverations However unlike normals he showed no sensitivity to the similarity of phonemes in the target string and errors peaked towards the ends of words rather than at their onsets Results are interpreted within an interactive activation framework Existing interactive accounts of aphasia are considered as well as some alternatives The implications of word position findings for accounts of serial order effects are also discussed |
