ABSTRACT

325Our visual perception is typically very rapid and accurate in spite of the problems we face in making sense of visual information. When looking at the world, we have to turn a two-dimensional retinal image into a rich three-dimensional perception of the environment. What kinds of cues do you think we use to see the world as it is rather than as it appears on the retina?

In spite of our perceptual abilities, we are nevertheless fooled by many visual illusions. We think we have a clear picture of the visual scene in front of us. However, we often fail to notice even fairly large changes in that scene. Why is visual perception so prone to such errors?
