Adaptation to Displaced Vision after Experience with Lesser Displacements

Abstract

Adaptation to vision displaced by a 30 diopter prism was greatest after prior experience with a 30 diopter prism, less after experience with a 20 diopter prism, and least after experience with prisms of 10 and 20 diopters. This order was reversed when aftereffects were observed under normal vision, i.e., undistorted by prisms.
