Implicit adaptation's effect on sensorimotor and motor confidence.

ABSTRACT: Sensorimotor adaptation maintains movement accuracy by counteracting perturbations or miscalibrations. It can operate explicitly, by consciously adjusting motor plans to correct errors, or implicitly, by automatically recalibrating sensorimotor mappings without altering the motor plan. While explicit adaptation is known to reduce sensorimotor confidence-the perceived likelihood of successful action-it is unclear whether implicit adaptation similarly affects confidence in sensorimotor judgments or motor awareness (knowledge of one's own limb position). To investigate this, participants made reaching movements to visual targets without seeing their hand. Cursor feedback followed an "error-clamped" trajectory: its radial position matched the hand, but its angular direction was fixed and indep
