Brown, L. B. & Houssiadas, L. (1965). The perception of illusions as a constancy phenomenon. British Journal of Psychology, 56(2/3), 135-141.

The view, recently revived, that the non-veridical perception of visual illusions results from size constancy processes set up by the depth features of flat figures has been tested with a series of eight stimuli. Data collected from experiments with 44 subjects suggest that this view applies only to a limited range of visual illusions and that, therefore, it has not the generality claimed by its proponents.
