Biological Psychology Test 3 Study Guide This is essentially a list of questions that TAs have derived from the lectures based on what they think are some of the main concepts. This is not a comprehensive list of what may be on the test. Use this as a study tool to help you recognize areas you may not understand. It is NOT a substitute for you own studying. Vision 1. Put in order the way light information is conveyed: ganglion cells, pupil, photoreceptors, retina, bipolar cells. Now put the same things in the order through which light passes. 2. Why do you have a blind spot? 3. What area has the greatest visual acuity (i.e. sharpness)? Why? 4. Contrast the area within the fovea and the area outside the fovea (periphery). 5. What is the purpose of amacrine cells (i.e. what aspect of vision are they responsible for?)? 6. What is the difference between rods and cones? 7. Walk through step-by-step the way light is transmitted to an electrical signal within neurons. Then explain its travel to the brain (we can discuss this more in the review session). 8. How many different “colors” of cones are there? How then can we perceive so many different colors? 9. Explain the two theories that account for color vision. 10.What is color constancy and how can we explain it? 11.What is the cause of color vision deficiency? 12.If I turned a dim pinpoint of light brighter, which of these would happen: more photoreceptors would be depolarized; the photoreceptors would become more hyperpolarized the photoreceptors will become more depolarized; the photoreceptors would transmit a new pattern of action potentials. 13.Describe the three kinds of ganglion cells and how they correspond to the retina and vision. 14. What would happen to people with primary visual cortex damage? 15.How are cells grouped in the visual cortex? What are several different types of cells in the visual cortex that are utilized in recognizing shapes? 16.What is area is important for facial recognition? Which hemisphere is this located in? 17.What is prosopanosia and what causes it? 18.What happens if you suture one eye closed on a kitten during the first weeks of life? What about both eyes? 19.What is an astigmatism? 20.What is retinal disparity and how does experience affect it? 21.Is sight possible without light?

22.What are the two ways to think about light? 23.With which type of light do we perceive color? 24.Where does light enter the eye? 25.What does light hit first after entering the eye? 26.What are the first cells to be activated in response to light? 27.What does increased tension on the lens do to your sight, and how do
