The Great Illusion Controversy: A Glimpse

Abstract

Beginning with Mueller-Lyer's original article in 1889 and continuing with subsequent studies, an attempt to translate and/or analyze theoretical explanations of the Mueller-Lyer illusion is well under way. Much new food for thought comes from these old studies.
