Please keep track of time. Writing an answer to an essay question involves composing a good coherent answer--not doing a "core-dump" of info. Please plan your answers and write legibly. It's the quality of the answer that counts! Good thinking and good luck!

3. If a right-handed person fixed their gaze on the dot, and the word CROSS.ROAD was superimposed on the dot for a very brief time, what would a normal person read?________________ What would a split brain person read?_____________
4. On the picture below, label each of the three arrows pointing at the various brain parts with two letters indicating two of the following answers, one of which is always a cortical lobe. You should thus end up with six letters, two on each arrow. a. frontal lobe
b. parietal lobe c. temporal lobe d. occipital lobe e. Wernicke's area f. Broca's area g. site of voluntary motor control h. visual projection area i. somatosensory projection area
Answer any 8 (but no more than 8) of the following 9 questions.
Joe Doaks has a problem. He has a strong sexual attraction to chickens and in particular, Rhode Island Reds. For some reason, it makes him uncomfortable. Describe a "fowl" dream he might have and tell his therapist about that illustrates Freud's theory of dreaming. Then use that dream to identify the different levels or types of dream and the dreamwork labelling the particular parts of the dream appropriately. Finally, if Freud is wrong and Hall and Cartwright (dream series) right, how would the dream and/or its interpretation be different?
Briefly summarize or define the following three principles of neural organization: a. doctrine of specific nerve energies b. encephalization (cephalization) c. topographic projection
One of the most powerful motivations is the motivation to sleep. We took some time to explore whether it is a life necessary need or simply a strong motivation. Take a stand on this issue and cite some good evidence for the position that you take.
Describe in some detail the events that occur in a simple reflex such as the "knee jerk" reflex that was demonstrated in class. Complete the figure below (the neural "wiring"), label each part of the reflex pathway, and describe (briefly) the neural and synaptic events that are involved at each stage.

Describe the role of the lateral and ventromedial hypothalamus in the control of eating using the regulator model of homeostasis that we developed in class. Include a brief description or simple statement or illustration (using the model) of the effects of destroying the VMH.
Claude Bernard (and Walter Cannon) advanced an evolutionary view of our "internal environment" that explains the adaptive function of the many homeostatic regulatory systems in our body. Summarize this view and show how it applies to temperature or body water regulation, what it has to do with the model of regulation we developed in class, and how motivation fits into that regulation.
For the following three theories of food regulation/control, briefly state the theory and then describe what implications it has for weight control. a) Schacter's externality theory b) restrained vs. unrestrained eating hypothesis c) fat cell/storage hypothesis
You have a large green dog who is very strange. You want to teach him/her to jump when you say "jump". Describe how you would do this using a) instrumental conditioning and
b) classical conditioning. Where relevant, describe the schedule of reinforcement you would use if you wanted this learning to last a long time. Also, if after learning, the dog also jumps when you say "pump" or "rump" or even "rum" what learning phenomenon would you say is being illustrated?
Briefly summarize Thorndike's Law of Effect and discuss the role it plays (when coupled with motivation) in replacing purely instinctual behavior in satisfying basic bodily needs. Finally, what aspect of Thorndike's view is contradicted by Kohler's work with chimpanzees using tools to solve problems?
Extra Credit: You fly to the planet SRAM where some things are backwards from the way they are on earth. The living cells there have large negative proteins trapped outside (along with potassium), and sodium and chloride trapped inside. Draw in the space below, the voltage changes that would occur during the action potential, labelling the axes (and their units), the resting potential, the threshold and the action potential.
