Using Virtual Technology to Promote Functional Communication in Aphasia: Preliminary Evidence From Interactive
Purpose:
We investigated the feasibility of using a virtual clinician (VC) to promote functional communication abilities of persons with aphasia (PWAs). We aimed to determine whether the quantity and quality of verbal output in dialogues with a VC would be the same or greater than those with a human clinician (HC).
Method:
Four PWAs practiced dialogues for 2 sessions each with a HC and VC. Dialogues from before and after practice were transcribed and analyzed for content. We compared measures taken before and after practice in the VC and HC conditions.
Results:
Results were mixed. Participants either produced more verbal output with the VC or showed no difference on this measure between the VC and HC conditions. Participants also showed some improvement in postpractice narratives.
Conclusion:
Results provide support for the feasibility and applicability of virtual technology to real-life communication contexts to improve functional communication in PWAs.
