Ebbinghaus illusion

The Ebbinghaus illusion is an optical illusion of relative size perception, named for its discoverer, the German psychologist Hermann Ebbinghaus (1850–1909). In the best-known version of the illusion, two circles of identical size are placed near to each other, and one is surrounded by large circles while the other is surrounded by small circles. As a result of the juxtaposition of circles, the central circle surrounded by large circles appears smaller than the central circle surrounded by small circles.
