Abstract
Varied both the size and inducing circles and the distance between inducing and test circles in a study of the Ebbinghaus or Titchener circles illusion using 15 Ss. Variation of the size of the context circles resulted in a systematic variation of the apparent size of the central test figure that was in accord with a comparative judgmental model of this illusion. However, increasing the distance of the context figures resulted in a decrease in the apparent size of the test figure regardless of the size of the context circles. This result is not predicted by a judgmental model and indicates a similarity between the Ebbinghaus and Delboeuf illusions. (PsycINFO Database Record (c) 2006 APA, all rights reserved).
