Size constancy is a perceptual phenomenon where the perceived size of an object remains constant despite changes in the distance from which it is viewed, ensuring that objects appear the same size even when their retinal image size changes. This ability relies on the brain's use of contextual information and depth cues to maintain a stable perception of the environment.
