1. What is a binocular depth cue? A monocular depth cue?  How can you tell the difference between a binocular depth cue and a monocular depth cue?

2. Be able to identify the difference between corresponding and noncorresponding retinal points in looking at a scene. What conditions produce each?

3. What is the horopter? Where is the horopter located in space? What is special about the retinal images of objects that are on the horopter? What is Panum's Area?

4. 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.

5. Imagine that you are sitting in your apartment and you look at various people/objects. Explain how retinal disparity changes as you look about the room.  How do those changes contribute to your understanding of spatial relationships?

6. Understand how binocular stereograms and anaglyphs produce their depth effects.  How do they work?  (Especially those cool 3D glasses.)  Why do we get 3D effects but they are still not completely realistic?  Imagine that I wanted to have you create a new kind of stereogram or anaglyph then how would you do it?

7. What is the size-distance issue with monocular depth cues? How does "linear perspective" work?  How can artists use linear perspective to both produce and mock 3D effects?

8. What are examples of monocular depth cues? How/why do the monocular depth cues work?

9. 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?  Think about how you might create an Ames-room illusion.

10. Why does J. J. Gibson think the Ames room illusion does not tell us much about daily perception?

11.  What is the fundamental problem in motion perception according to Corollary Discharge theory?  Understand how Corollary Discharge theory explains why we see an object in motion or not.  Understand how Corollary Discharge theory applies to the 3 examples discussed in class.

12. What is motion parallax? How does it operate? How does it contribute to object identification? How does it contribute to spatial location of objects?  How is it influenced by gaze location?

13.  What is stroboscopic motion?  Where do we encounter it in ordinary experience?  What is beta and phi motion?  How did Helmholtz explain stroboscopic motion?  What is a   problem for his explanation? Why would people say that stroboscopic motion is a model of daily vision?
