Abstract
Adults with aphasia gesture more than adults without aphasia. However, less is known about the role of gesture in different discourse contexts for individuals with different types of aphasia. In this study, we asked whether patterns of speech and gesture production of individuals with aphasia vary by aphasia and discourse type and also differ from the speech and gestures produced by adults without aphasia. We compared the amount, diversity, and complexity of speech and gesture production in adults with anomic or Broca's aphasia and adults with no aphasia (n = 20/group) in their first- versus third-person narratives. Adults with Broca's aphasia showed the lowest performance in their amount, diversity, and complexity of speech production, followed by adults with anomic aphasia and adults without aphasia. This pattern was reversed for gesture production. Speech and gesture production also varied by discourse context. Adults with either type of aphasia used a lower amount of and less diverse speech in third-person than in first-person narratives; this pattern was also reversed for gesture production. Overall, our results provide evidence for a compensatory role of gesture in aphasia communication. Adults with Broca's aphasia, who showed the greatest speech production difficulties, also relied most on gesture, and this pattern was particularly pronounced in the third-person narrative context.
