2015-01-30 In the Ebbinghaus illusion, a circle surrounded by smaller circles is perceived as larger than an identical one surrounded by larger circles. The illusion is reportedly weaker in individuals with (disorganized) schizophrenia or schizotypy than in controls, a finding that has been interpreted as evidence that both schizophrenia and schizotypy involve reduced contextual integration.

Ebbinghaus illusion

The Ebbinghaus illusion, in which a central target surrounded by larger context figures looks smaller than when surrounded by smaller context figures, is usually classified as a size contrast illusion. Thus “size contrast” is the dominant account of this effect. Therefore, size contrast as shown by the Ebbinghaus illusion is not a built-in property of the ventral pathway subserving vision for perception but a late development of it, and low sensitivity to the Ebbinghaus illusion in autism is not primary to the pathology. The Ebbinghaus illusion (or Titchener circles) is an optical illusion of relative size perception. Named for its discoverer, the German psychologist Hermann Ebbinghaus, the illusion was popularized in the English-speaking world by Edward B. Titchener in a 1901 textbook of experimental psychology, hence its alternative name "Titchener circles".

This illusion is named after Hermann Ebbinghaus, a pioneer in memory research, who likely discovered this illusion in the 1890s, but did not publish it in any specific publication. Rather, Titchener (whithout claiming authorship) published it in a 1901 textbook; thus it is also frequently called the Titchener illusion.
