An illusion stemming from this phenomenon places a (*) cylindrical object on a checkerboard and is an illustration of its "constancy."
Gunnar Svaetichin [svai-TEE-chin] provided the first biological evidence for one theory of this phenomenon and gives his name to its S-potentials. The Purkinje [purr-KIN-jee] effect explains a shift in this phenomenon from day to night time. It's not motivation, but Ewald Hering developed a model of this phenomenon with anabolic and catabolic phases known as "opponent-process" theory. An illusion stemming from this phenomenon places a (*) cylindrical object on a checkerboard and is an illustration of its "constancy." Young and Helmholtz devised a theory of this phenomenon, a common test of which places different numbers within a series of dots. For 10 points, name this sense stemming from rods and cones in the retina, which is partially explained by the trichromatic theory.
