AP PSYCHOLOGY

Detailed explanation-1: -Because they are a few inches apart, the retinal image of an object on one eye may be slightly different than the retinal image of the same object on the other eye. This is the depth cue known as binocular (retinal) disparity. The brain compares these two images as part of depth perception.

Detailed explanation-2: -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-3: -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-4: -Definition. Binocular disparity is a binocular depth cue produced by a difference in retinal projection of the same object onto left eye and right eye retinas as a result of a horizontal separation of the eyes.
