Exploring the Relationship between Feedback and Use-Dependent Learning
Use-dependent learning is a motor learning process that is thought to arise from the repetition of a specific movement pattern. Use-dependent learning is thought to underlie the refinement of motor skills, such that well-practiced actions become more accurate and consistent (the practice makes perfect phenomenon); however, this learning process also comes at the cost of biasing subsequent actions to be more similar to practiced ones. It was initially assumed that pure repetition of a movement was the only necessary condition to drive use-dependent learning, however recent studies suggest that some form of feedback may be required to cause this learning. I am interested in examining the interaction between use-dependent learning and learning processes that involve feedback in the form of errors or rewards. For this project, I will use reaching tasks to determine whether use-dependent learning is contingent upon repetition alone or is influenced by performance-related feedback.
