Many psychological studies in healthy and neurological disordered participants indicate the involvement of proprioceptive information in various aspects of perception and action. Vision is one of the most important organs which provide such proprioceptive information to nervous system (Visual proprioception', Gibson, 1979). In fact, a large field visual motion compels observers to perceive self-motion. We investigated the effect of the visual proprioceptive information on spatial and temporal sensory processing, using an immersive virtual reality system (CAVE) which can properly create large field three-dimensional visual stimuli essential for visual proprioception. Our experiments in the spatial domain have shown that the perceived depth order of two visual dots with horizontal disparities systematically varies depending on the direction of the visual motion. Those in the temporal domain have also shown that the long-lasting exposure of the visual motion modulates the perceived order of auditory as well as visual events-an event in the incoming field of the visual motion is perceived prior to that in the outgoing field. We discuss the implications of the results for the role of the visual proprioceptive information in maintaining perceptual constancy of the world and behaving in an adaptive manner during self-motion.
