Which of the following is an example of a monocular cue in visual perception?

• A. Linear perspective
• B. Retinal disparity
• C. Convergence
• D. Stereopsis

Answer: (A)

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, helping us judge distance and depth in a two-dimensional image.
2. Step 2: Review each option to determine if it requires one eye or both eyes. For example, retinal disparity and stereopsis involve comparing images from both eyes, so they are binocular cues.
3. Step 3: Recognize that convergence involves the inward movement of both eyes to focus on a close object, which also requires both eyes, making it a binocular cue.
4. Step 4: Identify linear perspective as a cue that involves parallel lines appearing to converge in the distance, which can be perceived with just one eye, making it a monocular cue.
5. Step 5: Conclude that among the options, linear perspective is the example of a monocular cue because it relies on visual information available to one eye to perceive depth.
