MIDTERM 2002 YOUR NAME _______________________ 9.00 Introduction to Psychology Spirited Away by the Midterm 17 October 2002 190 total points If you think animated feature films begin and end with Disney, you should see some of the work of Hayao Miyazaki. He has produced a series of entertaining and evocative movies. The latest is entitled “Spirited Away” and I decided to use it as the basis for the midterm. PLEASE NOTE: I am using the film for its story but you don't need to know anything about it in order to do well on this exam. If you think that the story is confusing you, please ask and we will explain the meaning of any question. We are not trying to be tricky. Write your answers on the exam. Use the back of pages if needed (Tell us where to look!). Good luck. NOTE: Even though this is fantasy with spirits, witches, etc., assume that the rules for our universe apply unless you are told otherwise. Same brains. Same mental process. Etc. SCORE p1 ____ of 5 p2 ____ of 20 p3 ____ of 30 p4 ____ of 25 p5 ____ of 25 p6 ____ of 20 p7 ____ of 20 p8 ____ of 30 TOTAL 1) (10 points) At the beginning of the movie, a 10-yr old girl, Chihiro, is in the back seat of the family car. She is sulking because they are moving to a new house and she didn’t want to go. She is staring out the left window as they drive through a town. This means that all the buildings appear to be moving from right to left as the car moves forward. When the car stops, she shifts her gaze to look at the buildings out of the right-side window. Do the buildings appear to move or not? Why? What does this tell us about vision – specifically, about the processing of motion? 2) (5) Her dad (being a dad) decides to take a short-cut. Soon they are racing down a dirt road into denser and denser forest. The car keeps hitting bumps. These scare the girl. When car hits a bump, she squeals. This is reflexive. That is simply they way she sounds when she is scared. If we are thinking in the language of learning theory, the physical sensation of the bumps would be called. a) the distal stimulus b) the operant condition c) the unconditioned stimulus d) the conditioned stimulus e) negative reinforcement f) the pits page 1 of 8MIDTERM 2002 YOUR NAME _______________________ 3) (5) And the squeals would be called a) the distal response b) the proximal stimulus c) the conditioned response d) the unconditioned response e) operant reinforcement f) popular music 4) (10) Along the side of the road are weird little statues. Sometimes they appear just before a bump so you have the sequence: Statue Æ Bump Æ squeal. Sometimes the statues appear where there is no bump and sometimes a bump is hit with no statue in sight. It happens that there have been statues before most bumps. However, there is no contingent relationship between statues and bumps. At the end of the road, there is a statue but no bump. Will Chihiro squeal? Please explain your answer. A good answer will use the appropriate terminology from whatever form of learning this might be. 5) (5) Oh yes, the end of the road. The short cut ends abruptly in front a building with narrow tunnel leading through it. The dad decides to explore. Chihiro thinks that this is A Bad Idea but dads never listen so they walk into the tunnel. It is dim in the tunnel. Chihiro notices that her colorful clothes now appear to be only shades of gray. Why? a) Chihiro’s cone photoreceptors do not work in dim (scotopic) light levels. b) Chihiro’s rod photoreceptors are subject to the problem of “univariance” which makes it impossible to tell one wavelength from another except by perceived brightness. c) Chihiro has only one type of rod photoreceptor. d) The visual system is not trichromatic at scotopic light levels. e) All of the above f) A & D g) A & C h) There is lots of dust in here. i) none of the above 6) (5) Eventually, they emerge into what looks like an abandoned waiting room. It is much brighter here (color vision is back) The windows are tinted. The sun, shining through the windows puts spots of light on the white wall. Conveniently, these are monochromatic (single wavelength) patches of light. One patch is a lovely 470 nanometers (nm). It looks blue. Another is 570 nm. It looks yellow. These two patches partially overlap. The mixture of 470 nm and 570 nm light, shining on a white wall will appear to be what color?_________________________ page 2 of 8MIDTERM 2002 YOUR NAME _______________________ 7) (5) If dad was carrying a spectrophotometer, he could measure the physical wavelength(s) reflected from the wall. He would find that the wavelength composition of the mixture of 470 nm and 570 nm light was ________________________ (feel free to add a brief explanation if you like). 8) (10) Suppose the Chihiro stares at the pattern on the wall for a while and suppose it looks like this: She fixates on the “a” for 30 seconds and then shifts her gaze to “b”. What does she see and why? (You can draw on the figure if you like but don’t forget the WHY part). 470 nm570 nm???ab 9) (5) Beyond the waiting room is a green field and across the field is what appears to be an abandoned town….except that there is a really good smell. This makes Chirhiro’s parents curious and hungry. If you were looking for the brain areas involved in this feeling of hunger, you might look in a) the hypothalamus b) the hippocampus c) the adrenal cortex d) the third ventrical e) any of these could be correct because it is not possible to localize brain areas for hunger. f) none of the above 10) (10) There are a lot of closed stores but, eventually, they find a food stall with a really great looking buffet. The parents try to get someone to take their order but no one appears, so they decide to just dig in and eat. Chihiro thinks that this is A Really Bad Idea but parents never listen. Chihiro wanders around. She finds a bridge leading across to a beautiful-looking building but on that bridge, she meets a boy named Haku who tells her to get out before it is too late. In fact, she is in big trouble (She doesn’t know page 3 of 8MIDTERM 2002 YOUR NAME _______________________ it yet.) Haku doesn’t know her, of course, but he wants to help her. Why? There is no one right answer to this. Just be sure your answer says something about the psychology of motivation.
