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: -A person who lost sight in one eye would only be able to see monocular cues. They would not be able to view objects in 3D or stereopsis. It is helpful to remember that true stereopsis is most advantageous only up to 3 feet. After this distance, it becomes a weak visual cue.

Detailed explanation-3: -Humans can perceive depth when viewing with one eye, and even when viewing a two-dimensional picture of a three-dimensional scene. However, viewing a real scene with both eyes produces a more compelling three-dimensional experience of immersive space and tangible solid objects.

Detailed explanation-4: -The brain perceives three main types of visual signals, called depth cues, to create a three-dimensional image: Binocular – Depth cue from both eyes. Monocular – Depth cue from one eye. Oculomotor – Depth cue from focusing on an object.
