Study Guide for Exam 3

1. Discuss the four theoretical approaches to depth perception.

2. Know all the monocular (pictorial), kinetic, and binocular cues to depth. Which give absolute and which give only relative distance information?

3. Be able to describe the physiological basis for stereopsis, starting with the concept of the horoptor and working up to specific areas in the occipital lobe.

4. Describe a) the three possible outcomes of dichoptic viewing and
   b) Panum's four rules of dichoptic viewing.

5. What do random dot stereograms tell us about stereopsis?

6. Be able to discuss the following terms: false fusion, Panum's limiting case, Panum's fusion area, cyclopean perception, stereoblindness

7. What is the common principle behind linear perspective, texture gradients, and relative size?

8. Why does viewing a picture through a rolled up tube increase the perception of depth?

9. What facts must a theory of shape perception be able to explain?

10. Be able to describe the five different types of eye-movements.

11. What factors determine which area of the retinal image will become the figure? What qualities does the figure have that the ground does not?

12. Be able to describe the Gestalt grouping principles and be able to either give or identify examples of each.

13. Compare the different theories of pattern (shape, form) perception.

14. Describe the information processing approach to form and factors that influence each stage.

15. Compare the bottom-up (data-driven) and top-down (conceptually driven) theories of form perception. Which is correct and why?

16. Be able to discuss the following terms: contrast sentivity function, textons, geons, recognition by components, subjective contours, visual masking, contingent aftereffects, Stroop effect

17. Be able to discuss and give examples of perceptual set. How does perceptual set influence scene perception?

18. What do ambiguous figures tell us about form perception?

19. Why does squinting at a bloch portrait help you to see it?

20. Compare the preattentive and focused attention stage of form perception.

21. Be able to describe the different types of constancies.

22. How is Emmert's Law related to size constancy?
