The cost of correcting for error during sensorimotor adaptation
Abstract
Improving the process of learning from error can play a critical role in applied settings such as rehabilitation. Previous work has generally focused on reward as a variable that may modulate learning. However, in response to an erroneous movement, the nervous system often engages a reflex that corrects for that error, thus expending time and energy. Here, we modulated this cost of error and found that increasing the cost increased how much the brain learned from error. Thus, the landscape of the loss associated with the act of correcting for error regulates the rates of sensorimotor learning.
