Adult Clinical Trial - Feedback, Motor Sequence Learning, & Brain

Status Completed

Clinical Trial Summary

Feedback delivered during motor practice can help promote motor skill learning, enhance confidence, and alter brain connectivity. However, the optimal way to provide feedback to promote learning, confidence and brain connectivity is unknown. This project will study how the feedback that is provided during practice of a movement skill can help people learn and build confidence and whether these correspond to changes in brain function. The investigators will measure motor skill performance, confidence, and resting state brain connectivity before and after a session of motor practice.

Clinical Trial Description

Positive social comparative feedback, which indicate to the learner that they are performing above average, is one way to enhance a learner's expectancies about future performance. Expectancies include the learners' perceived competence about their ability to perform the task, expectations about task outcome (success or failure), and predictions of extrinsic reward or positive experiences related to performance. Positive feedback during motor practice enhances expectancies, which is hypothesized to be rewarding to the learner, leading to better skill performance and learning. Reward is a powerful shaper of behavior. However, while social comparative feedback supports motor skill learning, it is unclear whether positive social comparative feedback induces a response in the dopamine reward network. Therefore, the purpose of this study is to determine the effects of social comparative feedback during motor practice on the functional connectivity of the reward neural network. The study aims to recruit 40 participants who will be randomized into 1 of 2 feedback groups (performance feedback or performance plus positive feedback). Participants will practice a motor sequence task on a single day and then return for retention performance testing about 24 hours later. Measures of brain function and brain structure will be collected before and after practice on day 1. Changes in performance (response time to complete a sequence) and self-efficacy will be measured from baseline to 24 hours later at retention. Changes in brain functional connectivity over practice on day 1 will be assessed in the reward network and the motor network. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
