Both theories are correct. There is evidence for both. Theories work together toaccount for how we visually experience color.Visual Perception Rules1.Size Constancy: object size remains constant regardless of distance or size ofimage on retinaPrevious experience with objectPresence of surrounding objectsDistance between object and personAmes Room. Violates the rule of size constancy. Tricks us.We think things are going to remain the same size regardless of wherethey are.2.Shape Constancy: recognize shape regardless of changes in angle or positionDepth PerceptionMonocular CuesoOne eye is needed to figure it out. Both eyes not needed to use this depthperception cue.oMotion parallaxThings closer to us go by us faster than those far away, whichmove more slowly.Road is whizzing by you, while mountain is just there.oOcclusion: one blocks another – closerWhatever blocks the other object is closer to youoRelative size: larger seems closerIf something is larger, we tend to think it is closer. Somethingfurther away is going to be smaller.This has to do with size constancy.Binocular CuesoYou need two eyes. This is for objects moving across the visual field.Important for moving objects.oConvergence: eyes closer together – closer objectFootball is approaching you. Eyes are more parallel when fartheraway, but as it gets closer, eyes are converging, going in.Closer or farther away from you.oRetinal disparityMoving across the field of vision.
Where image hits on retina are different because there is aphysical space between two retinas.A more on left side of visual field, in left eye, distance between Aand B is smaller, while in right eye, distance between A and B islarger. Means left side.We don’t see A as two different things.Keep track of things in our periphery.Object Perception TheoriesHow do we categorize things?1.Feature DetectionA ball is round. A chair has a backseat, etc.We learn these things as we have more experience with an object. Wethen learn the features that make up an object.Pattern recognition. We learn the patterns and features that make up anobject.One of the strong points of object perception, but we also learn thatcontext matters.We use context of things surrounding it. “The Cat.”2.Gestalt Theory: Context MattersYou can change someone’s perception of an object if you change thecontext.Figure groundoFace vs. wine glass. Example of priming.oFill in the missing information based on the context we haveactivated. Figure of the missing triangle.oProximity. We tend to group things on our visual field that arecloser together.
