For reasons of geometry, the projected images of nearby objects move more than those of distant ones. Also, the direction of movement across the retina depends on where we are pointing our eyes. Points closer to us than the target of our gaze appear to be moving in a direction opposite to our own; points farther away appear to be moving in the same direction we are. These patterns of movement provide another distance cue called __________.
A) interposition
B) motion parallax
C) synesthesia
D) apparent movement

Question

Quizplus · Accepted Answer

The patterns of movement described in the paragraph are known as motion parallax, which provides a depth cue based on the relative movement of nearby and distant objects as the observer moves their gaze or themselves. Interposition, synesthesia, and apparent movement are all different perceptual phenomena that do not relate to the specific patterns of movement discussed in the paragraph.
