Here are a few examples of questions that appeared on the final exams in a few different years. None of the topics covered below was covered this year. This is just to give you an idea of the TYPE of question you can expect. Note that for each question you are expected to draw on ALL of the readings (book chapter and 4 articles) for that topic area. Also included below is the preamble/instructions from one of the exams. THIS EXAM PAPER INCLUDES 2 BACK-PRINTED PAGES AND 6 QUESTIONS. YOU ARE RESPONSIBLE FOR ENSURING THAT YOUR COPY OF THE PAPER IS COMPLETE. BRING ANY DISCREPANCY TO THE ATTENTION OF YOUR INSTRUCTOR. PLEASE ANSWER ANY 4 OF THE 6 QUESTIONS. ONLY THE FIRST FOUR ANSWERS WILL BE MARKED. EACH QUESTION IS WORTH 25 MARKS. EACH ANSWER SHOULD OCCUPY NO MORE THAN 2 PAGES TYPED AND DOUBLE-SPACED OR PRINTED CLEARLY ON REGULAR LINED PAPER. YOU MAY CONSULT YOUR TEXTBOOK AND OTHER PRINTED REFERENCE MATERIALS BUT YOU ARE EXPECTED TO WORK ON YOUR ANSWERS ENTIRELY ON YOUR OWN -- DO NOT CONSULT WITH OTHER MEMBERS OF THE CLASS IN FORMULATING YOUR ANSWERS. INCLUDE YOUR NAME AND STUDENT NUMBER AT THE TOP OF EVERY PAGE YOU HAND IN. OBJECT RECOGNITION Evidence from behavioural neuroscience experiments suggests that faces are treated specially by the brain, and invoke completely different representations from those predicted by Marr's theory of object recognition. Discuss this position (and feel free to argue either for or against it) in light of your course readings for the topic of "object recognition". SPATIAL PROCESSING AND ATTENTION The brain does not have a single attention system, but rather, many different attentional systems that are specialized for different situations and tasks. Discuss this position in light of your course readings for the topic of "spatial processing and attention". SPATIAL VISION Spatial representations may be divided into two types, allocentric or world-centered, and egocentric or viewer-centered. Describe evidence, drawn from your course readings, for each of these two types of representations, commenting on where in the brain they may be formed and in what situations they might be used. MOTOR CONTROL AND PLANNING. The motor control system is comprised of a large number of brain areas involved in converting plans and decisions into actions. Suppose you were in your kitchen holding a piece of bread and you decided to make toast. Drawing on the readings in this section of the course, outline how you think this motor act would be encoded by neocortical neurons in your motor system, from the planning to the execution of the action. MOTOR CONTROL There is a widely held view, as described in the Banich textbook, that the brain's motor control circuits are organized hierarchically from spinal to cortical mechanisms. Outline the major neural circuits involved in this hierarchy, and describe what is known about the internal representations used to guide motor actions. (note: by "internal representations", I mean what sort of neural code is used, or in what form is the information internally coded). For the latter, you may base your answer on the examples from your course readings of 1) spinal neurons involved in leg extension, and 2) presumably higher level brain regions involved in learning a visually guided reaching task. Comment on why these multiple levels -- spinal versus cortical -- might exist, how their representations do or do not differ, and how the levels may interact in a hierarchical fashion. LANGUAGE Coltheart has presented a dual-route model of reading whereby words are read either in a whole-word fashion or via a sounding-out mechanism, whereas Plaut has more recently presented a single network that appears to handle both types of reading. Disucss the neuropsychological evidence both in favour of and against each of these models. Consider the neurobiological plausibility of each model. Also, Comment on what sort of language-related brain areas and internal representations would be predicted by each model, and what additional evidence would be required to choose between the two models.
