Which of the following is NOT a monocular cue used in the perception of visual stimuli?

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

Answer: (D)

Verified step by step guidance

1. Step 1: Understand what monocular cues are. Monocular cues are depth cues that can be perceived using only one eye. They help us judge distance and depth in a two-dimensional image.
2. Step 2: Review each option to determine if it is a monocular cue. Texture gradient, linear perspective, and interposition are all examples of monocular cues because they provide depth information from one eye.
3. Step 3: Define retinal disparity. Retinal disparity is the difference in images between the two eyes, which the brain uses to perceive depth. This requires both eyes and is therefore a binocular cue, not monocular.
4. Step 4: Compare retinal disparity with the other options and recognize that it is the only binocular cue listed, making it the correct answer to the question about which is NOT a monocular cue.
5. Step 5: Summarize that monocular cues include texture gradient, linear perspective, and interposition, while retinal disparity is a binocular cue involving both eyes.
