Perceptual constancy is the ability to perceive objects as having a constant shape, size, and color even when viewed from different angles or under different lighting conditions. This is accomplished through top-down processing, in which the brain uses prior knowledge and expectations to interpret sensory information. Therefore, choice C, top-down processing, is the best option. Difference thresholds (A) refer to the minimum difference between stimuli that a person can detect, proximity (B) refers to the tendency to group nearby objects together, and closure (D) refers to the tendency to complete incomplete figures to form meaningful objects. While these concepts may be relevant to perception, they are not directly related to perceptual constancy.
