Perrone's result, using a rigid box moving away from the observer, suggests that the contraction of the retinal image causes the observer to perceive that the box was moving away and getting smaller. The perception of the box getting smaller SEEMS to violate which of the following?
A) size constancy
B) shape constancy
C) figure-ground reversal
D) proximity

Question

Quizplus · Accepted Answer

Size constancy is the ability of the brain to perceive objects as having a constant size, regardless of their distance from the observer. Perrone's result suggests that the observer perceived the box as getting smaller as it moved away, which violates size constancy. The other options, shape constancy, figure-ground reversal, and proximity, are not related to the perceived change in size of the box.
