efference copy and sensory prediction
My new research in the Aphasia Research Lab investigates how abnormalities in auditory-motor prediction signals may contribute to speech production disorders. Specifically, we are exploring whether speakers with aphasia are impaired in their ability to detect acoustic deviations in their own voice, and how this may lead to errors in production. We are also exploring feedback training methods that could leverage other intact sensory systems to circumvent abnormal auditory processing.
