INTERACTION BETWEEN SENSORY SPATIAL AFTEREFFECTS AND PERSISTENCE OF RESPONSE FOLLOWING BEHAVIORAL COMPENSATION

INVESTIGATED SENSORY SPATIAL AFTEREFFECT, DUE TO PROLONGED STIMULATION, AND RESPONSE PERSISTENCE OF BEHAVIORAL COMPENSATION, DUE TO TRANSFORMATION OF SENSORY INPUT. IN EXP. I, USING TRANSFORMED VISUAL INPUT, IT WAS SHOWN THAT MAKING KINESTHETIC SPATIAL JUDGMENTS CAN BE A TRAINING PERIOD IN THE LEARNING OF NEW KINESTHETICALLY CONTROLLED RESPONSES. THE LACK OF VISUAL REINFORCEMENT IN THE POSTEXPOSURE PERIOD PRODUCES EXTINCTION. IN EXP. II, THE ACT OF MAKING A SINGLE SPATIAL JUDGMENT DURING THE PERIOD WHEN A KINESTHETIC SYSTEM WAS UNDERGOING ADAPTATION WAS SHOWN TO BE SUFFICIENT TO PRODUCE LASTING PERCEPTUAL DISTORTIONS, I.E., BEHAVIORAL COMPENSATION PERSISTING AFTER SENSORY EFFECTS DISSIPATE. EXP. III CONFIRMED THESE RESULTS. (PsycINFO Database Record (c) 2006 APA, all rights reserved). © 1968 American Psychological Association.
