AP PSYCHOLOGY

Detailed explanation-1: -The two slightly different images produced in both eyes are blended into one view when both eyes are open, and this is one of the ways in which human depth perception is possible. Retinal disparity is important in gauging how far away objects are.

Detailed explanation-2: -Binocular disparity refers to the difference in image location of an object seen by the left and right eyes, resulting from the eyes’ horizontal separation (parallax). The brain uses binocular disparity to extract depth information from the two-dimensional retinal images in stereopsis.

Detailed explanation-3: -In a natural, real life setting the retina in each eye forms a two-dimensional image of our surroundings. Each eye produces a slightly different image because the eyes are in different locations. Our brain processes these two images and combines them into one 3D visual experience.

Detailed explanation-4: -Binocular Disparity. Humans have two eyes. 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.

Detailed explanation-5: -That is, the binocular disparity between the two images is used by the nervous system to allow the perception of a three-dimensional world where the approximate distance of an object can be determined.
