| Q4 to Q7: 
 The term “episodic memory” was
 
 introduced by Tulving to refer to what he
 
 considered a uniquely human capacity—
 
 Linethe ability to recollect specific past events,
 
 (5)to travel back into the past in one’s own
 
 mind—as distinct from the capacity simply
 
 to use information acquired through past
 
 experiences.Subsequently, Clayton et al.
 
 developed criteria to test for episodic
 
 (10)memory in animals.According to these
 
 criteria, episodic memories are not of
 
 individual bits of information; they involve
 
 multiple components of a single event
 
 “bound” together.Clayton sought to
 
 (15)examine evidence of scrub jays’ accurate
 
 memory of “what,” “where,” and “when”
 
 information and their binding of this infor-
 
 mation.In the wild, these birds store food
 
 for retrieval later during periods of food
 
 (20)scarcity.Clayton’s experiment required
 
 jays to remember the type, location, and
 
 freshness of stored food based on a unique
 
 learning event.Crickets were stored in one
 
 location and peanuts in another.Jays
 
 (25)prefer crickets, but crickets degrade
 
 more quickly.Clayton’s birds switched
 
 their preference from crickets to peanuts
 
 once the food had been stored for a certain
 
 length of time, showing that they retain
 
 (30)information about the what, the where,
 
 and the when. Such experiments cannot,
 
 however, reveal whether the birds were
 
 reexperiencing the pastwhen retrieving the
 
 information.Clayton acknowledged this by
 
 using the term “episodic-like” memory.
 
 Q4:
 
 The primary purpose of the passage is to
 
 A. explain how the findings of a particular experiment have been interpreted and offer an alternative interpretation
 
 B. describe a particular experiment and point out one of its limitations
 
 C. present similarities between human memory and animal memory
 
 D. point out a flaw in the argument that a certain capacity is uniquely human
 
 E. account for the unexpected behavior of animal subjects in a particular experiment
 
 这题选B,可我没看出这篇文章点出了这个实验的什么局限(limitations)啊?相反,我倒是觉得E更加合适,解释了实验中发现的一个动物的没有预想到的行为。(就是可以有记忆)
 
 Q5:
 
 According to the passage, Clayton’s experiment depended on the fact that scrub jay
 
 A. recall “when” and “where” information more distinctly than “what” information
 
 B. are not able to retain information about a single past event for an indefinitely long period of time
 
 C. choose peanuts over crickets when the crickets have been stored for a long period of time
 
 D. choose crickets over peanuts whenever both are available
 
 E. prefer peanuts that have been stored for a short period to crickets that have been stored for a short period
 
 这题答案选C,但C不就是结果吗?可题目是问这个实验depend on什么fact。
 D更加合适,因为这个实验是基于当c和p都available的时候,小鸟会选C,所以当放了很长时间,小鸟选P了,这才是能够反映出实验证明的东西。如果当c和p都available的时候,小鸟会选p,那放了很长时间后,小鸟选p就不奇怪了。
 
 求各位大N讨论,谢谢!
