AP PSYCHOLOGY

Detailed explanation-1: -Retinal disparity is a binocular cue used to perceive depth between two near objects. It does so by comparing the different images from both retinas. Each eye receives different images because they are usually around two and half inches apart.

Detailed explanation-2: -If you hold your finger out at arm’s length and then look at it alternately with your left eye only and then your right eye only, the image of your finger relative to the world behind it will shift somewhat. This is binocular disparity, which helps provide the basis for the determination of depth.

Detailed explanation-3: -They actually rely on your retinal disparity to reconstruct the sense that a three-dimensional object is hidden in the image. They’re created by superimposing two images, one of the object as would be seen by your left eye and one of the same object as would be seen by your right eye.

Detailed explanation-4: -the slight difference between the right and left retinal images. When both eyes focus on an object, the different position of the eyes produces a disparity of visual angle, and a slightly different image is received by each retina.
