Article Synopsis
- The study explores how different types of feedback (reinforcement and error) influence movement exploration, revealing distinct roles for the basal ganglia (linked to reinforcement) and the cerebellum (linked to error correction).
- Experiments conducted with both neurotypical individuals and those with Parkinson's disease show that reinforcement feedback encourages exploration, while error feedback suppresses it; together they can counteract each other.
- Findings indicate that individuals with Parkinson's have reduced exploration abilities when receiving reinforcement feedback, which could inform strategies for neurorehabilitation.
When a musician practices a new song, hitting a correct note sounds pleasant while striking an incorrect note sounds unpleasant. Such reward and punishment feedback has been shown to differentially influence the ability to learn a new motor skill. Recent work has suggested that punishment leads to greater movement variability, which causes greater exploration and faster learning.
