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 the stimulus.
Visual
There are several types of perceptual constancies in visual perception:
Size constancy is one type of visual subjective constancy. Within a certain range, people’s perception of one particular object’s size will not change, regardless of changes in distance or the video size change on the retina. The perception of image is still based upon the actual size of the perceptual characteristics. According to optical principles, for the same object, the size of the image on the retina changes as the distance from the object to the observer changes. The greater the distance, the smaller the image is sensed by the retina. When someone is observing an object, although the distance of observation is different, the perceptional size is similar to the actual size. However, sensory and perception systems can be tricked by the use of illusions. Size constancy is related to distance, experience, and environment. Some examples of size constancy are Müller-Lyer illusion and Ponzo illusion. Another illusion experienced everyday is the size of the moon - when closer to the horizon, the moon appears larger. See moon illusion. Human perception is largely influenced by the environment; that is, the context in which the object is found.

In this video I describe perceptual constancy, which refers to the idea that we perceive a relatively stable and unchanging world despite the fact that sensory information is changing dramatically. I explain how this applies visually to size, brightness, and shape. We often forget this learning process because it occurred during infancy, but it is demonstrated clearly in previously blind individuals who must slowly learn how to see following eye surgery.

What is size constancy?
Goodale Lab Post Doctoral Fellow Irene Sperandio explains size constancy. Neuroscientists from Western University have taken the all-important first step towards understanding the neural basis of size constancy or the ability to see an object as having the same size despite the fact that its image on the retina changes constantly with viewing distance. The findings were revealed this week by Nature Neuroscience in a study titled, "Retinotopic activity in V1 reflects the perceived and not the retinal size of an afterimage."
