单选题{{B}}PASSAGE 1{{/B}} {{B}}To Err Is Human{{/B}}by Lewis Thomas Everyone must have had at least one personal experience with a computer error by this time. Bank balances are suddenly reported to have jumped from $379 into the millions, appeals for charitable contributions are mailed over and over to people with crazy sounding names at your address, department stores send the wrong bills, utility companies write that they're turning everything off, that sort of thing. If you manage to get in touch with someone and complain, you then get instantaneously typed, guilty letters from the same computer, saying, "Our computer was in error, and an adjustment is being made in your account." These are supposed to be the sheerest, blindest accidents. Mistakes are not believed to be the normal behavior of a good machine. If things go wrong, it must be a personal, human error, the result of fingering, tampering a button getting stuck, someone hitting the wrong key. The computer, at its normal best, is infallible. I wonder whether this can be true. After all, the whole point of computers is that they represent an extension of the human brain, vastly improved upon but nonetheless human, superhuman maybe. A good computer can think clearly and quickly enough to beat you at chess, and some of them have even been programmed to write obscure verse. They can do anything we can do, and more besides. It is not yet known whether a computer has its own consciousness, and it would be hard to find out about this. When you walk into one of those great halls now built for the huge machines, and standing listening, it is easy to imagine that the faint, distant noises are the sound of thinking, and the turning of the spools gives them the look of wild creatures rolling their eyes in the effort to concentrate, choking with information. But real thinking, and dreaming, are other matters. On the other hand, the evidence of something like an unconscious, equivalent to ours, are all around, in every mail. As extensions of the human brain, they have been constructed the same property of error, spontaneous, uncontrolled, and rich in possibilities.

单选题 Western juries have traditionally found eyewitness testimony to be the most convincing evidence in criminal trials. Seeing is believing, as the saying goes. In numerous cases, when witnesses pointed to the defendant, his or her fate was sealed. But how reliable is eyewitness testimony? Recent cases have suggested that despite our best intentions, we may unwittingly distort what we perceive. Artists and psychologists have long known that "seeing" is not a simple matter of recording visual input. People perceive the exterior world through a complex matrix of cultural expectations, personality traits, moods and life experiences. For example, researchers tested the cultural influence on perception by showing a set of optical illusions to various groups, and found that different groups responded in divergent ways. Accustomed to and inundated by perpendicular structures, Western Europeans succumbed easily to illusions based on rectangular lines. On the other hand, the Zulu people of South Africa, whose environment had been comprised almost entirely of circular forms (round houses, doors, etc.) did not fall prey to those linear illusions. Cultural expectations also influence the selectivity of our seeing. The amount of visual information that exists far exceeds our ability to process it, so we must filter that sensory input into recognizable images. In looking at a face, we do not see elongated ovals set in complex shadows and shading, we see eyes. And that filtering process is informed by what we perceive to be significant, which is influenced by cultural norms. Some cultures may emphasize differences in hair color or texture, others the shape of a nose or mouth, others the set of the eyes. But it is not only group expectations that color what we see, personality and mood fluctuation can also alter our perceptions. Orderly minds who shun ambiguity will see an off- center image as firmly fixed in the center. The same photograph of four young men allows for shifting interpretations based on our current feeling: a mood of happiness reveals boys enjoying a relaxing day, while anxiety changes the picture to students worrying about exams. In addition, numerous more prosaic factors affect our ability to record an image accurately. Duration of the encounter, proximity to the subject, lighting, and angle all affect our ability to see, and even stress may further undermine the accuracy of our perceptions. What will this mean for criminal trials? Juries have often been reluctant to convict without eyewitness identification. Blood samples, fingerprints, and the like do not resonate as deeply with juries as does direct testimony, and frequently require understanding of complex scientific technicalities. But as confidence in eyewitness testimony wanes, such circumstantial evidence may someday replace visual identification as the lynchpin of criminal trials.
