Perceptual Constancies: Shape Constancy

Sometimes an object whose actual shape cannot change seems to change with the angle of our view. We perceive the form of familiar objects as constant even while our retinal images of them change.













Even though our view of the cereal box changes in these images, we still maintain that the cereal box has a box-like shape. The different angles of the cereal boxes causes a change of shape on our retinas, but our brains are still able to retain its box-like configuration.
