Which of the following is a binocular cue for the perception of distance?

• A. Texture gradient
• B. Linear perspective
• C. Retinal disparity
• D. Interposition

Answer: (C)

Verified step by step guidance

1. Understand that binocular cues require the use of both eyes to perceive depth or distance, whereas monocular cues can be perceived with just one eye.
2. Review each option to determine if it involves both eyes: Texture gradient and linear perspective are monocular cues because they rely on visual information from one eye.
3. Interposition is also a monocular cue, where one object partially blocks another, indicating relative distance.
4. Retinal disparity is a binocular cue because it arises from the slight difference in images projected on each retina due to the eyes' horizontal separation.
5. Conclude that retinal disparity is the binocular cue for depth perception among the given options.
