Within Movement Error Correction Processes

Daily activities require complex control of many parts of the body (eyes, arms, hands, etc). Often errors are made during the production of these skills, and we quickly detect and correct errors and successfully meet our goals. Amazingly, we make these corrections often without conscious knowledge of the errors. We are studying the methods of correcting errors (timing & strategy) and neural processing needed to make this possible.

Error correction after speed and load perturbations

This experiment is being used to understand the behaviors used by healthy adult participants to successfully correct errors during the performance of a complex task. We are also using these behavioral results with neural imaging techniques to elucidate the neural processing mechanisms to enable online error correction.

Future Investigations 

 

The NMCL will examine the relationship between correcting errors during a motor skill and changing the cognitive expectations and demands during the task.
