Augmentation of Perceived Visual Error Improves Movement Control and Retention

Abstract

Previous research shows that the control of movement benefits from learning under error-augmented conditions. The present study examined how the enhancement of perceived visual error can increase accuracy and decrease variability in motor performance. Importantly, we show how this improved performance persists for five days. Using a virtual throwing task, skittles, subjects manipulated a lever arm with a single-joint elbow movement and released a virtual ball that traversed a concentric force field to hit a target. The ball
