Adaptation to displaced vision: Variations on the "prismatic-shaping" technique

Abstract

Adaptation to displaced vision was measured, using three variations on Howard's (1968) "prismatic shaping technique." Over a series of 40 trials, a lateral displacement of 11.3 deg was introduced either gradually or suddenly. Both the amount of adaptation (negative aftereffect) and the accuracy of target localization at the completion of 40 trials were found to be directly related to the "suddenness" with which the displacement was introduced. © 1971 Psychonomic Society, Inc.
