YOU ARE RESPONSIBLE FOR ENSURING THAT YOUR COPY OF THE EXAM IS COMPLETE. PLEASE BRING ANY DISCREPANCY TO THE ATTENTION OF THE INSTRUCTOR. The first three questions are worth 2 marks each, and the final two questions are worth 12 marks each. Please write your answers in sentence format in the booklet provided. The duration of the exam is 50 minutes. Good luck, and remember to budget your time appropriately. Short Answer Section Questions 1-3 are worth 2 marks each (1-2 sentence answers are appropriate, 3 sentences maximum) (1) Distinguish between two different ways in which the term “context” is used in memory research. (2 marks) Context may refer to the experimental environment in which the memory study takes place including things such as time of day, room, etc. However, context can also be used to describe the way in which items are encoded at the time of study. For example, a particular word may be studied in the context of a semantic encoding task, where participants might be asked to judge whether each presented word is an example of a living or non-living thing. (2) Describe what is meant by an “artificial grammar” in implicit learning research. (2 marks). Often in studies of implicit learning, strings of letters are generated according to different combinatory rules or ‘grammars.’ After being exposed to strings of letters generated from a particular grammar, subjects then must decide whether strings presented at the time of test belong to the previously exposed grammar or new grammar. Implicit learning is demonstrated when participants can discriminate between grammatical and ungrammatical letter strings at test. (3) Describe briefly what is meant by “the bias view” of implicit memory. (2 marks) The bias view of implicit memory posits that our initial interpretation of some event biases how we interpret that event upon subsequent exposure. Implicit memory operates by biasing the way in which we make sense of the world. For example our initial interpretation of an ambiguous figure often influences how we perceive that figure on subsequent occasions. Essay Answer Section 1 Please answer the following question. Question 4 is worth 12 marks (4) All other things being equal, the principle of parsimony dictates that the simpler the model of memory the better. In particular, unless there is strong scientific evidence indicating that a complex model can explain things that a simpler model cannot, the simpler model should be retained. Discuss the notion of parsimony with respect to research on the distinction between short-term and long-term memory, and briefly propose
