Speed–Accuracy Trade-Offs and Adaptation Deficits in Aphasia: Finding the Sweet Spot Between Overly Cautious and Incautious Responding

摘要

PurposeAfter stroke, how well do people with aphasia (PWA) adapt to the altered functioning of their language system? When completing a language-dependent task, how well do PWA balance speed and accuracy when the goal is to respond both as quickly and accurately as possible? The current work investigates adaptation theory () in the context of speed–accuracy trade-offs in a lexical decision task. PWA were predicted to set less beneficial speed–accuracy trade-offs than matched controls, and at least some PWA were predicted to present with adaptation deficits, with impaired accuracy or response times attributable to speed–accuracy trade-offs.
