Perceptual constancy, also called object constancy, or constancy phenomenon, the tendency of animals and humans to see familiar objects as having standard shape, size, colour, or location regardless of changes in the angle of perspective, distance, or lighting. The impression tends to conform to the object as it is or is assumed to be, rather than to the actual stimulus.

Perceptual Constancy. There is a tendency to maintain constancy (of size, color, and shape) in the perception of stimuli even though the stimuli have changed.
Perceptual learning refers to experience-induced improvements in the pick-up of information. Perceptual constancy describes the fact that, despite variable sensory input, perceptual representations typically correspond to stable properties of objects. Here, we show evidence of a strong link between perceptual learning and perceptual constancy: Perceptual learning depends on constancy Cited by: Perceptual constancy. Perceptual constancy refers to the tendency to perceive an object you are familiar with as having a constant shape, size, and brightness despite the stimuli changes that occur. Related Terms.

Perceptual constancy can be reduced if you are not very familiar with the object, or if there is a decrease in the number of environmental cues to assist with the object's identification. It is commonly believed that this high-level visual function, called “perceptual constancy,” is acquired through postnatal learning, building upon low-level functions that have developed earlier, such as image discrimination. However, we demonstrate here that before developing perceptual constancy, 3- to 4-month-old infants have a striking Cited by: Subjective constancy or perceptual constancy is the perception of an object or quality as constant even though our sensation of the object changes. While the physical characteristics of an object may not change, in an attempt to deal with our external world, our perceptual system has mechanisms that adjust to .
