Abstract
In its original form, the Morinaga illusion is the apparent misalignment of the physically aligned apexes of oppositely facing angles. Recently, the effect has been shown to occur also with similarly arranged lines, squares, and small circles (Day, Bellamy, & Norman, 1983). With larger circles similar in size to the angles, lines, and squares, the effect was negligible. The two experiments reported here were designed to ascertain whether the effect occurs with larger circles. The display, response mode, and method of measurement were different from those used earlier. The results indicate that the illusion, although small and relatively unstable, does occur with circles of about the same dimensions as the angles, lines, and squares of the earlier experiments.
