Limb-related sensory prediction errors and task-related performance errors facilitate human sensorimotor learning through separate mechanisms
by Anushka Oza, Adarsh Kumar, Apoorva Sharma, Pratik K. Mutha
The unpredictable nature of our world can introduce a variety of errors in our actions, including sensory prediction errors (SPEs) and task performance errors (TPEs). SPEs arise when our existing internal models of limb-environment properties and interactions become miscalibrated due to changes in the environment, while TPEs occur when environmental perturbations hinder achievement of task goals. The precise mechanisms employed... Читать дальше...
