Individuals with aphasia generate larger adaptive and corrective responses to suddenly introduced auditory perturbations

These findings suggest that measuring adaptive and corrective responses using an adaptation paradigm in PWA is both viable and informative, as the PWA exhibited different impairments in adaptive and corrective responses across the two perturbation schedules. Outcome differences in response to sudden versus gradual perturbations for the PWA may be explained by difficulties with the detection of auditory errors during speech. Perhaps a sudden perturbation schedule improves the adaptive and corrective abilities of PWA by increasing their agency over their speech errors. More studies are needed to further elucidate the critical mechanisms of auditory-motor adaptive and corrective responses in PWA.
