Which of the perceptual constancies cause us to perceive objects as being different from the retinal image they project?

Question

Quizplus · Accepted Answer

Shape constancy and size constancy allow us to perceive objects as being the same despite changes in the retinal image. For example, a door that is closed appears rectangular, but when it is open at an angle, the retinal image changes to a trapezoidal shape. Despite this change in the retinal image, we still perceive the door as rectangular due to shape constancy. Similarly, an object that is far away appears smaller on the retina than the same object up close. However, we still perceive the object as being the same size due to size constancy. Brightness and color constancy refer to the perception of an object's brightness and color remaining constant despite changes in lighting conditions, not despite changes in the retinal image.
