The compensation for movement-produced changes of object orientation

Abstract

When one moves forward, one views objects to the side of one's path successively from different directions. In the mover's visual field, such objects change their orientation; relative to him they undergo a partial rotation. Although this rotation is given in several ways, it is hardly ever perceived. This is due to a compensating process that takes O's change in position relative to the object into account. We demonstrated the existence of this compensating process and measured the accuracy with which it operates by means of a device that made an object turn in response to O's position change so that the normal rotation of a stationary object relative to the moving O could be augmented or diminished to various degrees. © 1974 Psychonomic Society, Inc.
