AP PSYCHOLOGY

Detailed explanation-1: -Example: When a man watches his wife walk away from him, her image on his retina gets smaller and smaller, but he doesn’t assume she’s shrinking.

Detailed explanation-2: -Binocular disparity, resulting from the differences between the retinal images of the two eyes, plays a fundamental role in the formation of stereoscopic vision and depth perception [1]. Generally, a greater difference (disparity) between the two images indicates that the objects are closer to each other (Fig.

Detailed explanation-3: -Retinal Disparity Examples When one alternates between using the left and right field of vision, the object will appear to move slightly. This example illustrates that the left and right eyes capture slightly different visual images of the object.

Detailed explanation-4: -Retinal disparity is produced in humans (and in most higher vertebrates with two frontally directed eyes) by the separation of the eyes which causes the eyes to have different angles of objects or scenes. It is the foundation of stereoscopic vision.

Detailed explanation-5: -With both eyes open, the blind spots are not perceived because the visual fields of the two eyes overlap. Indeed, even with one eye closed, the blind spot can be difficult to detect subjectively because of the ability of the brain to “fill in” or ignore the missing portion of the image.
