Visual capture in visual illusions

Visual capture is the resolution of visual-tactual conflicts in favor of vision. In each previous demonstration of this phenomenon, a distorted optic array, or some mechanical analog for a distorted optic array, has produced a conflict between erroneous visual information and presumably veridical tactual information. The present experiments demonstrate visual capture in the Müller-Lyer and Ponzo illusions in the absence of any distortions of the optic array.
