Question

which depth perception list contains an item that does not belong with the others?
relative motion, convergence, monocular cues
monocular cues, interposition, relative height
retinal disparity, binocular cues, convergence
relative size, monocular cues, linear perspective

Explanation:

• Monocular cues are depth perception cues that can be perceived with one eye. Examples include interposition (one object blocking another), relative height (objects higher in the visual field are perceived as farther away), relative size (larger objects are perceived as closer), and linear perspective (parallel lines converging in the distance).
• Binocular cues require both eyes. Retinal disparity (the difference in the images received by each eye) and convergence (the inward turning of the eyes as an object gets closer) are binocular cues.
• In the first option “relative motion, convergence, monocular cues”, convergence is a binocular cue while relative motion and monocular cues are related to monocular or different (relative motion can be a monocular or binocular cue in some contexts but here convergence as a binocular cue makes this list inconsistent). The other options have items that are all monocular cues (second and fourth options) or all binocular - related (third option).

Answer:

relative motion, convergence, monocular cues
