The Ponzo illusion illustrates the principle of:
A) lighting effects in the retinal image that function as depth cues.
B) size-distance invariance and the powerful influence of linear perspective on size perception.
C) perceived size of an afterimage that is proportional to the distance of the surface on which it is projected.
D) shape-slant invariance, where the perceived shape of an object depends on its perceived slant.

Question

Quizplus · Accepted Answer

The Ponzo illusion demonstrates how our perception of an object's size can be influenced by its background context, specifically linear perspective, which tricks our brain into thinking one object is further away and therefore must be larger, even though the objects are the same size. This is an example of size-distance invariance.
