Abstract

We showed a novel visual illusion of filling-in occurring at the blind spot. We tried to see what is perceived in the blind spot when its surrounding visual information perceptually faded. It was found that when the surrounding itself perceptually disappeared under three cases of perceptual fading phenomena (transient-induced fading, contrast decrement disappearance, and Troxler fading), the blind spot was perceptually filled-in by information outside its immediate surround. Three movies are supplied to demonstrate the illusory phenomena.
