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 1000 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 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 ill 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. ”
Interrogation for“thought crimes”hasn’t come into reality partly due to the dependence off ______.
选项
答案
clumsy MRl scanning equipment and extremely powerful magnets
解析
同义转述题。本题考查,由于什么原因,对“思想犯罪”进行审讯还未成为现实。原文第四段第 二句提到,这种情景还仅仅存在于科幻小说中。因为到目前为止,读脑实验还需要依赖于笨重的磁共振扫描设备和异常强大的磁场。题干中的due to与原文中的because相对应,the dependence on是对原文rely on的同义转述,故答案为clumsy MRI scanning equipment and extremely powerful magnets。
