Using luminous stimuli in a dark room, Ss were required to judge the apparent depth location of shafts filling half the space between the ingoing and outgoing fins of the Mueller-Lyer illusion. Under these conditions there is a reversal of the apparent depth location of the shafts as compared with the usual M-L illusion. This finding is contrary to a prediction derived from the misapplied size-constancy theory but can be interpreted in terms of the size-distance principle.
