PSYC 305L Lecture Notes - Lecture 12: Subjective Constancy, Binocular Disparity, Parallax
Document Summary
Perceptual constancy: the achievement of perceiving the constant properties of objects in the world (their sizes, shapes, etc. ) despite changes in the sensory information we receive changes caused by variations in our viewing circumstances. Size constancy: the achievement of perceiving the constant size of objects in the world despite changes in the size of the retinal image that result from variations in viewing distance. If you happen to be far away from the object you"re viewing, then the image cast onto your retinas by that object will be relatively small. The size of the object has remained constant though. Shape constancy: the achievement of perceiving the constant shape of objects in the world despite changes in the shape of the retinal image that result from variations in viewing angle. Brightness constancy: the achievement of perceiving the constant brightness of objects in the world despite changes in the light reaching the eye that result from variations in illumination, a. unconscious inference.
