Question

Quizplus · Accepted Answer

Shape constancy allows us to perceive objects as maintaining their shape regardless of the angle they are viewed from, while size constancy allows us to perceive objects as maintaining their size even as they move closer to or farther away from us. These two perceptual constancies together cause us to perceive objects as different from the retinal image they project. Brightness constancy and color constancy, on the other hand, allow us to perceive objects as maintaining their brightness and color even as the lighting conditions change.
