abstract：:It has been claimed that an illusory figure is prevented from occurring when there is contrary evidence to occlusion, eg when the inducers are pictorial representations of 'complete' three-dimensional (3-D) objects. However, it was recently shown that illusory figures may also be induced by such pictorially 3-D induce...
