Consolidation refers to the process ofa. creating larger units from information in working memory so that it can be stored more easily.b. transferring information from working memory to long-term memory.c. practicing a task until the knowledge moves from declarative to procedural memory, so that it can be done automatically.d. transferring long-term memories from the hippocampus to the cortex, so that they will be more permanent.13. Which sentence best describes the human memory system?a. Memory is essentially infallible.b. Memory often makes errors because it is a poorly designed system.c. Memory often doesn't perform the way people want itto, because the system has other purposes besides literal recording of experience.d. Memory often fails, but the reasons are currently largely unknown.14. You cannot remember what you had for lunch last Tuesday because the memory is blocked by memories for meals you've had since. This is most likely due toa. anterograde amnesia.b. retrograde amnesia.c. proactive interference.d. retroactive interference.15. Flashbulb memorya. is memory in which details are especially accurate.b. is another name for iconic memory (visual sensory memory).c. is memory for important events in which details are especially vivid but not particularly accurate.d. is the closest thing to photographic memory that has been empirically demonstrated (also known as eidetic imagery).16. Schemas are useful fora. organizing memories.b. filling in forgotten details.c. inferring unobserved facts.d. all of the above.17. You can recall the Longhorns' logo not by picturing it, butby knowing that it is orange, looks like the head of a cow, and has horns protruding from either side. This knowledge is based on a ____ representation.a. pictorialb. phonologicalc. propositionald. prototype18. Biologists group animals into vertebrates and invertebrates based on whether they have a spine. This is best described by a(n) ____ model.a. defining attributeb. prototypec. exemplard. neural network19. When deciding whether a piece of music qualifies as jazz,you consider a number of factors, including the instruments involved, the style of vocals (if present), the tempo, and the degree of improvisation. Each factor has adifferent weight and the final decision is based on the summed input from all of them. This is best described by a(n) ____ model.a. defining attributeb. prototypec. exemplard. neural network20. An exemplar isa. any real member of a category.b. any idealized representative of a category.c. a real object that exemplifies the typical features of its category.d. none of the above.21. Insight learning is characterized by all of the following excepta. a need for expertise in the particular problem domain.b. progress based on viewing the problem in a different way.c. sudden rapid progress after a long period of stagnation.d. often discovering the solution while engaged in a different task.22. Suppose you are working on a jigsaw puzzle. What are the operators for this problem?a. the piecesb. possible arrangements of piecesc. placing a piece in a particular place, or hooking two pieces togetherd. the initial configuration of all the pieces jumbled in the box, along with the goal configuration in which the puzzle has been completed23. In blackjack, the optimal choice (hit, stand, etc.) can always be calculated based on the cards that are currently showing and the cards that have been dealt in previous hands. However, hardly anyone has the memory capacity to perfectly track which cards have previously appeared (especially when 8-12 decks are used simultaneously). Therefore there are a number of card counting strategies in which the player only keeps track of some summary statistic of the past cards (usually a running count, such as+1 for a number card and -2 for a face card). The player then plays the optimal choice conditioned on this running count, rather than on a full description of all the cards. The theory behind this strategy is an example of aa. normative model.b. descriptive model.c. bounded rationality model.d. defining attribute model.24. In backgammon, calculation of the optimal move would involve determining probabilities of all future rolls of the dice and is thus practically
