Subjective constancy

Subjective constancy or perceptual constancy is the perception of an object or quality as constant even though our sensation of the object changes.[1] 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 the stimulus.[2]

Visual

There are several types of perceptual constancies in visual perception:

Ponzo illusion: Top line is perceived as larger than the bottom line, though they are identical in size.
The facts behind color-constancy phenomena...are that we require fine color discriminations less frequently than gross discriminations, and when gross discriminations enable us to maintain focus on objects of prime interest, we 'systematically overlook' differences beyond the necessary degree of fineness. The mechanism which accomplishes this 'systematic overlooking' is the information-processing system of the organism, and the principle according to which it is accomplished is that this system never expands more of its capacity on a given perceptual task than is necessary according to the current needs and interests of the agent.
