Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Healthy Adults group 1
Effects of speech variability on speech motor learning
This intervention will examine whether reducing normal variability of speech could improve error detection and speech motor learning. We will design training tasks to change subjects' speech variability. We will train subjects to decrease/decrease their speech variability. Upon completing the training tasks, subjects will complete a motor learning task.
Healthy Adults group 2
Effects of error-detection training on speech motor learning
This intervention will examine whether improving subjects' ability to detect and estimate auditory perturbation could improve speech motor learning. For this purpose, we will design training tasks to change subjects' estimation of the perturbation magnitude. After completing the training tasks, subjects will complete the motor learning task.
Healthy Adults group 3
Contributions of error awareness to speech motor learning
This intervention will examine the contributions of error awareness to speech motor learning. Subjects will produce a target word while receiving perturbed auditory feedback with different magnitudes. Subjects will be trained to indicate the magnitude of the error they perceived with or without visual feedback.
Healthy Adults group 4
Enhancing auditory-to-motor mapping with augmented visual feedback
This intervention will determine the contributions of enhanced auditory-to-motor mappings to speech motor learning. We will design training tasks in which we will use visual feedback to provide feedback regarding subjects' accuracy of auditory-to-motor mapping.
Healthy Adults group 5
Effects of enhanced auditory-motor awareness on speech motor learning
In this intervention, subjects will be trained to control their articulators more accurately and be more aware of their articulators' position and their auditory consequences. After the training tasks, subjects will complete a motor learning task.
