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 the external world, the human perceptual system has mechanisms that adjust to the stimulus.[2]
