This study examines perceptual changes that accompany motor learning for a balancing task. Perceptual changes in an upright state were demonstrated using an experimental method that involves the use of a specially designed but unstable stool capable of a lateral slide as well as roll rotation of the seat surface. Subjects were asked to keep the seat surface horizontal during the motor learning phase, in which the lateral slide occurred in synchronization with shifts in virtual roll about the rotatory axis. Perceptual changes were evaluated from a measure of the psychologically upright postures of each subject. Significant results from statistical analyses showed that psychologically upright postures were inversely affected by the direction of seat movement and roll rotation during the motor learning phase.
