Brief 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, which may be applied to people who have communication disorders. 15 participants will be enrolled into this part of the study and can expect to be on study for 3-4 visits of 2-4 hours each.
Detailed 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 over the course of 5 years. Participants can expect to be on study for up to 3 weeks.
The entire study is composed of 8 experiments and 6 interventions. The present record represents the experiments involving magnetoencephalographic (MEG) imaging, i.e. Experiment 5: Behavioral and neural responses to external alterations of speech variability.
This paradigm modulates the perceived speech variability of participants through three different altered auditory feedback sessions: an inward-pushing feedback perturbation that decreases perceived variability by playing back participants' speech closer to the center of their vowel distributions, an outward-pushing feedback perturbation that increases perceived variability by playing back participants' speech farther from the center of their vowel distributions, and a normal feedback condition in which speech feedback is played back without perturbation. Participants will complete this paradigm during MEG imaging, which will noninvasively measure auditory cortical activity evoked during speech production and playback.
