Title visual phantoms (stationary phantoms)
Free Keywords
Description When a dark-to-light luminance grating is occluded by a dark occluder, the dark regions of the grating appear to cross in front of the occluder.
This illusion was first discovered by Rosenbach (1902) and developed by Tynan and Sekuler (1975) as ‘moving phantoms’ because of its strong dependence on motion. It was later revealed that phantoms can be generated by flickering the grating (flickering phantoms) (Genter and Weisstein, 1981) as well as by low-luminance stationary gratings under dark adaptation (stationary phantoms) (Gyoba 1983). Moreover, we found that dark adaptation is not necessary for stationary phantoms, because many people see stationary phantoms in photopic vision when inducing gratings are of low spatial frequency and of low contrast.
