Which perceptual principles are used to help explain the moon illusion?

Question

Quizplus · Accepted Answer

The moon illusion is an optical illusion that makes the moon appear larger when it is near the horizon than when it is high in the sky. This illusion is caused by a combination of perceptual principles, including overlap and size constancy. Overlap refers to the fact that the moon appears to overlap the horizon when it is near the horizon, which makes it appear larger. Size constancy refers to the fact that we perceive objects as being the same size regardless of their distance from us, which makes the moon appear larger when it is near the horizon because it is closer to us.
