Behavioral and Neural Measures of Speech Motor Control
University of Wisconsin, Madison
Summary
The purpose of this research study is to understand how the brain processes and controls speech in healthy people. The investigators are doing this research because it will help identify the mechanisms that allow people to perceive their own speech errors and to learn new speech sounds. 117 participants will be enrolled into this part of the study and can expect to be on study between 1 day (Experiment 1) and 4 weeks (Experiment 2).
Description
The overall study (Establishing the clinical utility of sensorimotor adaptation for speech rehabilitation) aims to understand how cognitive, perceptual, and motor processes are integrated in the control of speech movements. The investigators study how this complex skill is performed in healthy speakers to understand how this system functions, how this skill relates to the perception of speech, and what role different parts of the brain play in this process. Different studies look at how speech motor control is executed, maintained, and changed. Overall, the study will recruit 329 participants…

Inclusion Criteria: * English-speaking adults * normal hearing and speech * no history of stroke or neurological conditions Exclusion Criteria: * Native language other than English * Any neurological disorders other than the disorder of interest * Any history of hearing disorders * Uncorrected vision problems that prevent participants from seeing visually-presented stimuli * Significant cognitive impairments that prevent participants from carrying out the task or from giving informed consent * Vulnerable populations (minors and prisoners)
Interventions
- BehavioralExp 3 Speaking Task
Participant will sit in front of a computer screen in a quiet room and to produce speech based on what is on the screen. Participant may see real words or nonsense words to read. Investigators may play sounds through headphones and ask the participant to repeat them. Participant speech will be recorded by a microphone. This task takes about one hour to complete.
