Quizplus · Accepted Answer

Binocular disparity is the difference in the images in the two eyes, and stereopsis is the impression of depth that results from this information. Choice A (Deletion; accretion) is incorrect as deletion and accretion refer to how objects are seen when they move across the visual field, not to binocular vision. Choice B (Accretion; deletion) is also incorrect for the same reason. Choice C (Binocular disparity; convergence) is partially correct, but convergence refers to the muscles in the eyes working together to focus on an object, not to the perception of depth.
