Question

Quizplus · Accepted Answer

Perceptual constancy, the ability to perceive objects as unchanging despite changes in sensory input, is a result of top-down processing. This means that our knowledge and expectations about objects, as well as our past experiences, guide and shape our perception. This allows us to perceive color, shape, and size variations in an object as true to its actual form, even as illumination and retinal image change.
