Surface decomposition accompanying the perception of transparency.

At the retina, each location can have only 1 value of luminance or color. When transparency is perceived, however, different surface qualities can be redistributed to 2 or more apparently superimposed layers. Six experiments explored the characteristics of this surface decomposition. The decomposition occurs rapidly (within 60 msec), affects even early stages of visual processing (influencing the strength of the McCollough effect), and involves attributes such as texture and motion, as well as color and brightness, when a transparent surface appears to extend over areas that are physically identical to the background.
