Shape constancy allows us to perceive objects as maintaining their shape despite changes in the image projected on the retina. In the case of the door, even when it is viewed at different angles or partially covered, our brain still perceives it as a rectangle. Size constancy would refer to our ability to perceive the size of an object as remaining the same despite changes in its distance from us. Color and brightness constancy refer to perceiving an object as maintaining a consistent color or brightness even under varying lighting conditions.
