Question

Quizplus · Accepted Answer

Stereopsis is the ability to perceive depth using binocular vision, meaning that both eyes work together to create a three-dimensional image. This ability typically emerges around 4 months of age and becomes more refined over time. Therefore, option B is the correct answer. Optical expansion refers to the visual cue that objects appear larger as they move closer to the viewer, but it is not related to depth perception. Binocular disparity is another term for stereopsis and is related to the ability to perceive depth using both eyes. Monocular vision refers to the ability to perceive depth using only one eye, but it is not as precise as stereopsis.
