Which of the following perceptual organizational principles provides information about depth?
Motion parallax
Shape constancy
Relative height
Retinal disparity
Answer is D. Aren't A and C also depth cues?
But aren't monocular cues depth cues just with one eye? Depth can be perceived with one eye, no? And motion parallax and relative height are monocular depth cues.
