A terminology is developed for perceptual constancy which permits useful mathematical treatment. This is illustrated by discussing a particular form of constancy for which mathematics is particularly simple. Other cases which need more elaborate mathematics can be discussed in same way. This formulation of constancy problem enables empiricist approach to perception to be formulated more concretely. Instead of saying simply that learning is involved we are able to go some way towards saying what has to be learnt. It is suggested that constancy can be established by conditioning each element of an ‘ equivalence class’ of states of stimulation to same group of responses. This idea needs much more elaboration and investigation (Taylor, 1956), and we do not maintain that it is only possible mechanism. Experimental results on protracted wearing of distorting spectacles are reported and discussed in light of above principles.
