Where Does an Anorthoscopic Image Appear?

Abstract

Two experiments were performed to examine where anorthoscopic images appear. In Exp. 1, in which a narrow slit was used, the images were seen as spatially compressed, but also as spatially displaced along each direction of movement even when two patterns were moved simultaneously and in different directions. These results are incompatible with the retinal painting hypothesis. In Exp. 2, in which a wider slit was used, anorthoscopic images appeared immediately after a pattern entered and left the slit. The two images were considered to depend on temporal changes of parts of a pattern passing across left and right edges of the slit, respectively.
