Aphasia, Stroke
Conditions
Brief summary
The goal of this clinical trial is to test the effects of recursive self-feedback procedures on spontaneous speech production in stroke survivors with impaired speech production (aphasia). The main question it aims to answer is: • To what extent can stroke survivors with aphasia use their self-feedback alone to improve their spontaneous speech production? Participants will be engaged in the following activities: * They will perform language and cognitive tasks. * Afterwards, they will receive treatments using tablets and headphones at no cost to them. * The experimental treatments (recursive self-feedback procedures) entails responding to prompts, listening to playbacks of their speech response and attempt to minimize/correct the errors in the next attempt. This process will be repeated multiple times per prompt. * The experimental treatments are two: an adaptive version that adapts the complexity of the treatment prompt and a non-adaptive version that does not adapt task complexity. * Researchers will compare the experimental treatments to see if both have similar effects on improving spontaneous speech production.
Interventions
BEHAVIORALAdaptive recursive self-feedback procedure
The intervention uses self-feedback alone to improve speech production. It adapts the complexity of the treatment tasks.
BEHAVIORALNon-adaptive recursive self-feedback procedure
The intervention uses self-feedback alone to improve speech production. However, it does not adapt the complexity of the treatment tasks.
