Which perceptual effect is a binocular depth cue?

Question

Quizplus · Accepted Answer

Retinal disparity is a binocular depth cue that occurs because our eyes are a few inches apart from each other. This means that each eye sees a slightly different image of the same object. The difference between these two retinal images is called retinal disparity. The brain uses this information to perceive depth and distance. The other options listed, relative size, linear perspective, and interposition, are monocular depth cues that can be perceived with just one eye.
