Repetition deficits in three aphasic syndromes.

This study examined the repetition errors of three aphasic subgroups during a repetition task. A total of 95 subjects, including 32 conduction, 38 Broca's, and 25 Wernicke's aphasics, repeated phrases and sentences from the Repeating Phrases Subtest of the Boston Diagnostic Aphasia Examination. Conduction aphasics exhibited a greater number of phonemic attempts, word revisions, and word and phrase repetitions. Broca's aphasics demonstrated more phonemic errors and omissions. Finally, Wernicke's aphasics showed more unrelated words and jargon.
