- 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.
- Describe a) the three possible outcomes of dichoptic viewing and
b) Panum's four rules of dichoptic viewing.
- What do random dot stereograms tell us about stereopsis?
- Be able to discuss the following terms: false fusion, Panum's limiting case, Panum's fusion area, cyclopean perception, stereoblindness
- What is the common principle behind linear perspective, texture gradients, and relative size?
- Why does viewing a picture through a rolled up tube increase the perception of depth?
- What facts must a theory of shape perception be able to explain?
- Be able to describe the five different types of eye-movements.
- What factors determine which area of the retinal image will become the figure? What qualities does the figure have that the ground does not?

- Compare the different theories of pattern (shape, form) perception.
- Describe the information processing approach to form and factors that influence each stage.
- Compare the bottom-up (data-driven) and top-down (conceptually driven) theories of form perception. Which is correct and why?
- Be able to discuss the following terms: contrast sentivity function, textons, geons, recognition by components, subjective contours, visual masking, contingent aftereffects, Stroop effect
