1. What is a binocular depth cue? Understand the binocular depth cues that were discussed in class.

2. Be able to identify the difference between corresponding and noncorresponding retinal points. What is the horopter? What is special about the retinal images of objects that are on the horopter? What is special about the horopter in terms of describing everyday depth perception?

3. Diagram two objects, one of which is in front of the horopter and another object that is beyond the horopter, and indicate where their retinal images will be located. Understand the difference between crossed and uncrossed disparity.

4. Understand how stereo photographs, anaglyphs, and single image stereograms produce depth effects.

5. What is a monocular depth cue? Understand the types of monocular cues that were discussed in class.

6. What is an "Ames room"? Understand how an Ames room is constructed to create its illusion. Is it a size illusion or a depth illusion?

7. What is "corollary discharge theory"? Understand how corollary discharge theory applies to concrete situations in which you may be moving (or not) and an object may be moving (or not).

8. Understand how corollary discharge theory accounts for the effects we discussed in class.

9. What is motion parallax? How does motion parallax contribute to the location of objects in space.

10. What is the autokinetic effect? Explain how corollary discharge theory accounts for these effects.

11. What is speed constancy and velocity transposition? What is happening on the retina in the case of speed constancy?

12. What is the difference between beta and phi motion? What is seen in each case? Which one did Gestalt psychology consider more important? Why?

13. What is stroboscopic motion? Understand how the "wagon wheel" illusion works.

14. What are the Gestalt principles of figure-ground organization and pragnanz? How do they apply to Rubin's Vase and the Necker cube.

15. What are the Gestalt grouping principles?

16. What is "change blindness"? What does it suggest about object perception?
