25、F.G.H.I.J.K.L.M.N.O.Section B(总题数：1，分数：71.00)The Blessing and Curse of the People Who Never ForgetA handful of people can recall almost every day of their lives in enormous detailand after years of research, neuroscientists are finally beginning to understand how they do it.A For most of us, memory

26、is a mess of blurred and faded pictures of our lives. As much as we would like to cling on to our past, even the saddest moments can be washed away with time.B Ask Nima Veiseh what he was doing for any day in the past 15 years, however, and he will give you the details of the weather, what he was we

27、aring, or even what side of the train he was sitting on his journey to work. “My memory is like a library of video tapes, walk-throughs of every day of my life from waking to sleeping,“ he explains.C Veiseh can even put a date on when those tapes started recording: 15 December 2000, when he met his

28、first girlfriend at his best friends 16th birthday party. He had always had a good memory, but the thrill of young love seems to have shifted a gear in his mind: from now on, he would start recording his whole life in detail. “I could tell you everything about every day after that.“D Needless to say

29、, people like Veiseh are of great interest to neuroscientists (神经科学专家) hoping to understand the way the brain records our lives. A couple of recent papers have finally opened a window on these peoples extraordinary minds. And such research might even suggest ways for us all to relive our past with g

30、reater clarity.E “Highly superior autobiographical memory“ (or HSAM for short) , first came to light in the early 2000s, with a young woman named Jill Price. Emailing the neuroscientist and memory researcher Jim McGaugh one day, she claimed that she could recall every day of her life since the age o

31、f 12. Could he help explain her experiences?F McGaugh invited her to his lab, and began to test her: he would give her a date and ask her to tell him about the world events on that day. True to her word, she was correct almost every time. G It didnt take long for magazines and documentary film-maker

32、s to come to understand her “total recall“, and thanks to the subsequent media interest, a few dozen other subjects (including Veiseh) have since come forward and contacted the team at the University of California, Irvine. H Interestingly, their memories are highly self-centred: although they can re

33、member “autobiographical“ life events in extraordinary detail, they seem to be no better than average at recalling impersonal information, such as random (任意选取的) lists of words. Nor are they necessarily better at remembering a round of drinks, say. And although their memories are vast, they are stil

34、l likely to suffer from “false memories“. Clearly, there is no such thing as a “perfect“ memorytheir extraordinary minds are still using the same flawed tools that the rest of us rely on. The question is, how? I Lawrence Patihis at the University of Southern Mississippi recently studied around 20 pe

35、ople with HSAM and found that they scored particularly high on two measures: fantasy proneness (取向) and absorption. Fantasy proneness could be considered a tendency to imagine and daydream, whereas absorption is the tendency to allow your mind to become fully absorbed in an activityto pay complete a

36、ttention to the sensations (感受) and the experiences. “Im extremely sensitive to sounds, smells and visual detail,“ explains Nicole Donohue, who has taken part in many of these studies. “I definitely feel things more strongly than the average person.“ J The absorption helps them to establish strong f

37、oundations for recollection, says Patihis, and the fantasy proneness means that they revisit those memories again and again in the coming weeks and months. Each time this initial memory trace is “replayed“, it becomes even stronger. In some ways, you probably go through that process after a big even

38、t like your wedding daybut the difference is that thanks to their other psychological tendencies, the HSAM subjects are doing it day in, day out, for the whole of their lives. K Not everyone with a tendency to fantasise will develop HSAM, though, so Patihis suggests that something must have caused t

39、hem to think so much about their past. “Maybe some experience in their childhood meant that they became obsessed (着迷) with calendars and what happened to them,“ says Patihis. L The people with HSAM Ive interviewed would certainly agree that it can be a mixed blessing. On the plus side, it allows you

40、 to relive the most transformative and enriching experiences. Veiseh, for instance, travelled a lot in his youth. In his spare time, he visited the local art galleries, and the paintings are now lodged deep in his autobiographical memories. M “ Imagine being able to remember every painting, on every

41、 wall, in every gallery space, between nearly 40 countries,“ he says. “Thats a big education in art by itself.“ With this comprehensive knowledge of the history of art, he has since become a professional painter. N Donohue, now a history teacher, agrees that it helped during certain parts of her edu

42、cation: “I can definitely remember what I learned on certain days at school. I could imagine what the teacher was saying or what it looked like in the book.“ O Not everyone with HSAM has experienced these benefits, however. Viewing the past in high definition can also make it very difficult to get o

43、ver pain and regret. “It can be very hard to forget embarrassing moments,“ says Donohue. “You feel the same emotionsit is just as raw, just as fresh.You cant turn off that stream of memories, no matter how hard you try.“ Veiseh agrees: “It is like having these open woundsthey are just a part of you,

44、“ he says.P This means they often have to make a special effort to lay the past to rest. Bill, for instance, often gets painful “flashbacks“, in which unwanted memories intrude into his consciousness, but overall he has chosen to see it as the best way of avoiding repeating the same mistakes. “Some

45、people are absorbed in the past but not open to new memories, but thats not the case for me. I look forward to each day and experiencing something new.“（分数：71.0）(1).People with HSAM have the same memory as ordinary people when it comes to impersonal information.（分数：7.1）A.B.C.D.E.F.G.H.I.J.K.L.M.N.O.
