Adaptation to displaced vision: Evidence for transfer of adaptation and long-lasting aftereffects

Abstract

Aftereffects following a single exposure to visual rearrangement last for 48 h and longer. Following multiple spaced exposures to visual rearrangement, aftereffects persisted for at least 2 weeks. Over the course of the multiple exposures, subjects showed diminished scatter when pointing without sight of hand to visual targets but did not show diminished constant errors. Adaptation achieved in one visuomotor transferred nearly perfectly to a test situation involving somewhat different movement demands. © 1977 Psychonomic Society, Inc.
