1. What is a binocular depth cue? What is the difference between a binocular cue and a monocular cue?

2. Be able to identify the difference between corresponding and noncorresponding retinal points. 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?

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. Be able to identify the type of disparity in a diagram.

5. Imagine that you are sitting in class and you look at various people/objects. Explain how retinal disparity changes as you look about the room.

6. Understand how binocular stereograms, anaglyphs, and single image stereograms produce depth effects.

7. What is a monocular depth cue? What are examples of monocular depth cues? Be able to identify cues in a diagram. How/why do the monocular depth cues work? What is "linear perspective"? How does the technique work?

8. 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?

9. What is our absolute threshold for movement of an object? What is speed constancy and velocity transposition? What is happening on the retina? Does speed of an image across the retina predict our experience of object speed? Why or why not?

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

11. Understand how corollary discharge theory accounts for the case examples we discussed in class.

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

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

14. What are ambiguous figures? Why did Gestalt psychology consider them important?

15. What is "Pragnanz"? What are the grouping principles? Be able to apply the grouping principles to specific cases as was done in class. What is the scientific issue with the use of the grouping principles?

16. What is motion parallax? What case made Gibson understand the importance of motion parallax in depth judgment? How does it operate? How does it contribute to object identification? How does it contribute to depth/distance judgments?
