What are the four types of perceptual constancy?

The four perceptual constancies are shape, size, color, and brightness

  • the light that a surface seems to reflect gives a perception of the lightness of the surface.
  • the percieved brightness of an object remains the same despite changing conditions of illumination.

Why does shape constancy occur?

Shape constancy is similar to size constancy in that it relies largely on the perception of distance. Regardless of changes to an object’s orientation (such as a door opening), the shape of the object is perceived the same. That is the actual shape of the object is sensed as changing but then perceived as the same.
