Scientists have developed a computerised mind-reading technique which lets them accurately predict the images that people are looking at by using scanners to study brain activity.
The breakthrough by American scientists took MRI (磁共振成像) scanning equipment normally used in hospital diagnosis to observe patterns of brain activity when a subject examined a range of black and white photographs. Then a computer was able to correctly predict in nine out of ten cases which image people were focused on. Guesswork would have been accurate only eight times in every 1,000 attempts.
The study raises the possibility in the future of the technology being harnessed to visualise scenes from a person’s dreams or memory. Writing in the journal Nature, the scientists, led by Dr Jack Gallant from the University of California at Berkeley, said, "Our results suggest that it may soon be possible to reconstruct a picture of a person’s visual experience from measurements of brain activity alone. Imagine a general brain reading device that could reconstruct a picture of a person’s visual experience at any moment in time."
It will inevitably also raise fears that a suspect’s brain could be interrogated (询问) against his will, raising the nightmarish possibility of interrogation for "thought crimes". The researchers say this is currently firmly in the realm of science fiction because the technique can only be applied to visual images and, to date, the experiments rely on clumsy MRI scanning equipment and extremely powerful magnets. The software decoder itself has to be adapted to each individual during hours of training while in the scanner.
However the team have warned about potential privacy issues in the future when scanning techniques improve. "It is possible that decoding brain activity could have serious ethical and privacy implications downstream in, say, the 30-to 50-year time frame," said Prof Gallant. "We believe strongly that no one should be subjected to any form of brain reading process involuntarily, or without complete informed consent." [br] Mind-reading researchers believe that interrogation for "thought crimes" is still______for the moment.
选项
答案
impossible/unavailable/in the realm of science fiction
解析
根据interrogation for“thought crimes”定位在原文倒数第二段。原文提到了对这种情况的两种态度。首句提到了感情倾向:nightmarish(恶梦似的)。第二句提到了现实可能性上的认识:这种技术(this)目前肯定只存在于科幻小说中(currently firmly in the realm of science fiction).注意句中的this的指代意义。题干要求填入的是这种技术目前的水平,所以填in the realm of science fiction或者填入表示“不可能的,不现实的”的词,如impossible/unavailable。
