Abstract

In the present study, a visuomotor adaptation paradigm was used to determine whether proprioception is calibrated during visually guided movements. A full vision group (FV) was given vision of a cursor representing hand position and was asked to aim towards visible targets. A no vision group (NV) performed the same task without vision of the cursor and was given knowledge of results (KR) after movement completion. A directional bias was introduced between the location of the cursor and the location of the hand in an adaptation phase, which resulted in a deviation to the right of the intended target. Of interest was whether participants would still show rightward deviations in a post-test series of trials in which vision was removed (aftereffects). The NV group presented strong aftereffects. However, the FV group only showed modest aftereffects early in the post-test, which rapidly decayed over the course of the post-test. Further analyses showed that the presence of those early aftereffects was due to an offline influence of vision on movement planning.
