What this Trial Is About
Researchers are exploring how individual differences in the way people use hearing and physical sensations while speaking affect their response to visual feedback during speech tasks. This study aims to find out if a computational model that measures these differences can predict who benefits most from adding visual feedback when auditory feedback is altered. Healthy adults aged 18 to 45, who speak English dominantly and have normal hearing and speech abilities, will participate. Participants first complete two versions of an altered auditory feedback task without visual feedback. One version introduces and removes altered feedback repeatedly in short runs, while the other presents altered feedback once for a longer period. These baseline tasks help estimate how much each person relies on hearing versus physical sensations using a computational model called SimpleDIVA. Next, participants repeat the adaptive task but with real-time visual-acoustic biofeedback showing the altered sound and a visual target. During the single study visit, researchers measure how much the visual feedback improves participants' ability to adjust to the altered auditory signals by comparing performance with and without the visual display. They will analyze whether the individual sensory feedback profile predicts this improvement. Participants undergo hearing and speech screenings before starting, and the main outcome focuses on the difference in compensation magnitude between the two feedback conditions during the visit.
