PSYCH 1XX3 Lecture Notes - Lecture 8: Subjective Constancy, Retina, Color Constancy
Document Summary
Our world would be an extremely confusing place if we interpreted every perceptual variation in a visual stimulus as belonging to a different stimulus. Example: when looking for a dog will recognize it even if its on the other side of the playground rather than by your side even though the image on your retina would be very much smaller. If your dog were sitting under a red fluorescent sign, you wouldn"t fail to recognize her because your dog is white and this one has a reddish cast. It is probably the rule rather than the exception that a specific object will look somewhat differently every time we look at it; fortunately our perceptual system can handle these variations. Perceptual constancy refers to our ability to perceive an object as unchanging even though the visual image that the object produces is constantly changing. There are several types of perceptual constancies: 5 types of perceptual constancies.
