Thus, for example, the main quantitative measure by which contemporary psychophysicists assess color constancy, known as asymmetric color matching (Wyszecki and Stiles, 1982, 281–293), involves asking subjects to change the chromaticity (or lightness, in lightness constancy experiments) of a test patch under one illuminant until it perceptually matches a standard patch under a different illuminant. Analyzing such experiments, this article responds to Pizlo’s claim that much work on shape constancy before 1985 confused problems of shape ambiguity with problems of shape constancy. Perceptual constancy is the tendency to see familiar objects as having standard shape, size, color, or location, regardless of changes in the angle of perspective, distance, or lighting. the tendency to perceive an object's shape as constant despite changes in the shape of the object's retinal image due to the object's changing orientation.
