PSY345H5 Lecture Notes - Lecture 6: Depth Perception, Subjective Constancy, Blurr
Document Summary
Visual system is keen component in maintaining the constancy of the perception. We use information about the size of the retina image to get arepresentation of the actual size. Challenge: object is 3dimensional but we perceive it on 2 dimensional. The x-axis horitzontal location can be explicit representation on the retine: if the position of the object changes on the y axis, it can also be explicitly represented on the retina, explicit representation. What about 3rd dimension: z coordinate associated with depth. The presence of the 3rd dimension is represented only implicitly. The tak of the brain is to use these cues in order to understand the. Second: two images will be identical in the retina even though they are different have to use all the cues available in the visual system in order to make the correct inference. Muscle related related to activity of ocular motor.
