Shape Constancy (Plummer)

Sometimes referred to as Subjective Constancy, Shape Constancy is a lot like Size Constancy in many ways. The visual system will sometimes interpret items of identical dimensions as differing in size, based on their viewing angle. Below there is a photo of 3 identical doors. As a door opens, its visual angle decreases and it begins to appear different in shape.
