  "Dave, stop. Stop, will you? Stop, Dave. Will you stop, Dave?” So the supercomputer HAL pleads with the implacable astronaut Dave Bowman in a famous and weirdly poignant scene toward the end of Stanley Kubrick’s 2001: A Space Odyssey. Bowman, having nearly been sent to a deep-space death by the malfunctioning machine, is calmly, coldly disconnecting the memory circuits that control its artificial ?
  
  brain. “Dave, my mind is going,” HAL says, forlornly. “I can feel it. I can feel it.”
  
  I can feel it, too. Over the past few years I’ve had an uncomfortable sense that someone, or something, has been tinkering with my brain, remapping the neural circuitry, reprogramming the memory. My mind isn’t going—so far as I can tell—but it’s changing. I’m not thinking the way I used to think. I can feel it most strongly when I’m reading. Immersing myself in a book or a lengthy article used to be easy. My mind would get caught up in the narrative or the turns of the argument, and I’d spend hours strolling through long stretches of prose. That’s rarely the case anymore. Now my concentration often starts to drift after two or three pages. I get fidgety, lose the thread, begin looking for something else to do. I feel as if I’m always dragging my wayward brain back to the text. The deep reading that used to come naturally has become a struggle.
  
  I think I know what’s going on. For more than a decade now, I’ve been spending a lot of time online, searching and surfing and sometimes adding to the great databases of the Internet. The Web has been a godsend to me as a writer. Research that once required days in the stacks or periodical rooms of libraries can now be done in minutes. A few Google searches, some quick clicks on hyperlinks, and I’ve got the telltale fact or pithy quote I was after. Even when I’m not working, I’m as likely as not to be foraging in the Web’s info-thickets—reading and writing e-mails, scanning headlines and blog posts, watching videos and listening to podcasts, or just tripping from link to link to link. (Unlike footnotes, to which they’re sometimes likened, hyperlinks don’t merely point to related works; they propel you toward them.)
  
  For me, as for others, the Net is becoming a universal medium, the conduit for most of the information that flows through my eyes and ears and into my mind. The advantages of having immediate access to such an incredibly rich store of information are many, and they’ve been widely described and duly applauded. “The perfect recall of silicon memory,” Wired’s Clive Thompson has written, “can be an enormous boon to thinking.” But that boon comes at a price. As the media theorist Marshall McLuhan pointed out in the 1960s, media are not just passive channels of information. They supply the stuff of thought, but they also shape the process of thought. And what the Net seems to be doing is chipping away my capacity for concentration and contemplation. My mind now expects to take in information the way the Net distributes it: in a swiftly moving stream of particles. Once I was a scuba diver in the sea of words. Now I zip along the surface like a guy on a Jet Ski.
  
  I’m not the only one. When I mention my troubles with reading to friends and acquaintances—literary types, most of them—many say they’re having similar experiences. The more they use the Web, the more they have to fight to stay focused on long pieces of writing. Some of the bloggers I follow have also begun mentioning the phenomenon. Scott Karp, who writes a blog about online media, recently confessed that he has stopped reading books altogether. “I was a lit major in college, and used to be [a] voracious book reader,” he wrote. “What happened?” He speculates on the answer: “What if I do all my reading on the web not so much because the way I read has changed, i.e. I’m just seeking convenience, but because the way I THINK has changed?”
  
  Bruce Friedman, who blogs regularly about the use of computers in medicine, also has described how the Internet has altered his mental habits. “I now have almost totally lost the ability to read and absorb a longish article on the web or in print,” he wrote earlier this year. A pathologist who has long been on the faculty of the University of Michigan Medical School, Friedman elaborated on his comment in a telephone conversation with me. His thinking, he said, has taken on a “staccato” quality, reflecting the way he quickly scans short passages of text from many sources online. “I can’t read War and Peace anymore,” he admitted. “I’ve lost the ability to do that. Even a blog post of more than three or four paragraphs is too much to absorb. I skim it.”
  
  Anecdotes alone don’t prove much. And we still await the long-term neurological and psychological experiments that will provide a definitive picture of how Internet use affects cognition. But a recently published study of online research habits, conducted by scholars from University College London, suggests that we may well be in the midst of a sea change in the way we read and think. As part of the five-year research program, the scholars examined computer logs documenting the behavior of visitors to two popular research sites, one operated by the British Library and one by a U.K. educational consortium, that provide access to journal articles, e-books, and other sources of written information. They found that people using the sites exhibited “a form of skimming activity,” hopping from one source to another and rarely returning to any source they’d already visited. They typically read no more than one or two pages of an article or book before they would “bounce” out to another site. Sometimes they’d save a long article, but there’s no evidence that they ever went back and actually read it. The authors of the study report:
  
  It is clear that users are not reading online in the traditional sense; indeed there are signs that new forms of “reading” are emerging as users “power browse” horizontally through titles, contents pages and abstracts going for quick wins. It almost seems that they go online to avoid reading in the traditional sense.
  
  Thanks to the ubiquity of text on the Internet, not to mention the popularity of text-messaging on cell phones, we may well be reading more today than we did in the 1970s or 1980s, when television was our medium of choice. But it’s a different kind of reading, and behind it lies a different kind of thinking—perhaps even a new sense of the self. “We are not only what we read,” says Maryanne Wolf, a developmental psychologist at Tufts University and the author of Proust and the Squid: The Story and Science of the Reading Brain. “We are how we read.” Wolf worries that the style of reading promoted by the Net, a style that puts “efficiency” and “immediacy” above all else, may be weakening our capacity for the kind of deep reading that emerged when an earlier technology, the printing press, made long and complex works of prose commonplace. When we read online, she says, we tend to become “mere decoders of information.” Our ability to interpret text, to make the rich mental connections that form when we read deeply and without distraction, remains largely disengaged.
  
  Reading, explains Wolf, is not an instinctive skill for human beings. It’s not etched into our genes the way speech is. We have to teach our minds how to translate the symbolic characters we see into the language we understand. And the media or other technologies we use in learning and practicing the craft of reading play an important part in shaping the neural circuits inside our brains. Experiments demonstrate that readers of ideograms, such as the Chinese, develop a mental circuitry for reading that is very different from the circuitry found in those of us whose written language employs an alphabet. The variations extend across many regions of the brain, including those that govern such essential cognitive functions as memory and the interpretation of visual and auditory stimuli. We can expect as well that the circuits woven by our use of the Net will be different from those woven by our reading of books and other printed works.
  
  Sometime in 1882, Friedrich Nietzsche bought a typewriter—a Malling-Hansen Writing Ball, to be precise. His vision was failing, and keeping his eyes focused on a page had become exhausting and painful, often bringing on crushing headaches. He had been forced to curtail his writing, and he feared that he would soon have to give it up. The typewriter rescued him, at least for a time. Once he had mastered touch-typing, he was able to write with his eyes closed, using only the tips of his fingers. Words could once again flow from his mind to the page.
  
  But the machine had a subtler effect on his work. One of Nietzsche’s friends, a composer, noticed a change in the style of his writing. His already terse prose had become even tighter, more telegraphic. “Perhaps you will through this instrument even take to a new idiom,” the friend wrote in a letter, noting that, in his own work, his “‘thoughts’ in music and language often depend on the quality of pen and paper.”[em06]

给予你想要的任何东西:Google在让我们变傻吗

作者:Nicholas Carr
  
  信息太丰富了,我们受用不尽,也不忘感恩戴德,却往往忽视了要付出的代价。“网络似乎粉碎了我专注与沉思的能力。现如今,我的脑袋就盼着以网络提供信息的方式来获取信息:飞快的微粒运动。”
  
  《大西洋月刊》刊文剖析互联网一代大脑退化历程,认为新阅读风格使人退回中世纪
  
  “戴夫,停下。停下好吗?停下,戴夫。你能停下吗,戴夫?”
  
  这个著名的场景出现在库布里克的电影《2001:太空漫游》的片尾,乃超级电脑HAL恳求宇航员戴夫·鲍曼手下留情,放他一条生路。由于电脑故障,戴夫被送入茫茫外空,前路未卜,目的地不明,只好“视死如不归”。最后,他对HAL下了手,平静而冷酷地切断了它的内存(记忆体)电路。
  
  “戴夫,我的思想要没了。”HAL绝望地说。“我感觉得到。我感觉得到。”(康慨/译)
  
  网络粉碎专注与沉思的能力
  
  当尼古拉斯·卡尔想起HAL的哀号,不由得脸皮有些酥麻,手脚略感冰凉。“我也感觉得到。”他说。
  
  卡尔在2008年7~8月号的《大西洋月刊》撰文,以《Google是否让我们越变越傻》为题,痛苦地剖析自己和互联网一代的大脑退化历程。“过去几年来,我老有一种不祥之感,觉得有什么人,或什么东西,一直在我脑袋里捣鼓个不停,重绘我的‘脑电图’,重写我的‘脑内存’。”他写道。“我的思想倒没跑掉——到目前为止我还能这么说,但它正在改变。”
  
  他注意到,过去读一本书或一篇长文章时,总是不费什么劲儿,脑袋瓜子就专注地跟着其中的叙述或论点,转个没完。可如今这都不灵了。“现在,往往读过了两三页,我的注意力就漂走了。”
  
  卡尔找到了原因。过去这十多年来,他在网上花了好多时间,在互联网的信息汪洋中冲浪、搜寻。对作家而言,网络就像个天上掉下来的聚宝盆,过去要在书堆里花上好几天做的研究,现在几分钟就齐活。Google几下,动两下鼠标,一切就都有了。“对我来说,”卡尔写道,“对别人也是如此,网络正在变成一种万有媒介,一种管道,经由它,信息流过我的眼、耳,进入我的思想。”
  
  信息太丰富了,我们受用不尽,也不忘感恩戴德,却往往忽视了要付出的代价。“网络似乎粉碎了我专注与沉思的能力。现如今,我的脑袋就盼着以网络提供信息的方式来获取信息:飞快的微粒运动。”
  
  网络新阅读方式:海量浏览
  
  卡尔不是唯一一个遇到此种问题的人。长期在密歇根医学院任教的布鲁斯·弗里德曼,今年早些时候也在自己的blog上写到互联网如何改变了他的思维习惯。“现在我已几乎完全丧失了阅读稍长些文章的能力,不管是在网上,还是在纸上。”他在电话里告诉卡尔,他的思维呈现出一种“碎读”特性,源自上网快速浏览多方短文的习惯。“我再也读不了《战争与和平》了。”弗里德曼承认,“我失去了这个本事。即便是一篇blog,哪怕超过了三四段,也难以下咽。我瞅一眼就跑。”
  
  伦敦大学学院以5年时间做了一个网络研读习惯的研究。学者们以两个学术网站为对象——它们均提供电子期刊、电子书及其他文字信息的在线阅读,分析它们的浏览记录,结果发现,读者总是忙于一篇又一篇地浏览,且极少回看已经访问过的文章。他们打开一篇文章或一本书,通常读上一两页,便“蹦”到另一个地方去了。报告说:“很明显,用户们不是在以传统方式进行在线阅读,相反,一种新‘阅读’方式的迹象已经出现:用户们在标题、内容页和摘要之间进行着一视同仁的‘海量浏览’,以求快速得到结果。这几乎可被视为:他们上网正是为了回避传统意义上的阅读。”
  
  打字机让尼采的写作风格发生变化
  
  互联网改变的不仅是我们的阅读方式,或许还有我们的思维方式,甚至我们的自我。塔夫茨大学的心理学家、《普鲁斯特与鱿鱼:阅读思维的科学与故事》一书作者玛雅妮·沃尔夫说:“我们并非只由阅读的内容定义,我们也被我们阅读的方式所定义。”她担心,将“效率”和“直接”置于一切之上的新阅读风格,或会减低我们进行深度阅读的能力。几百年前的印刷术,令阅读长且复杂的作品成为家常之事,如今的互联网技术莫非使它退回了又短又简单的中世纪?沃尔夫说,上网阅读时,我们充其量只是一台“信息解码器”,而我们专注地进行深度阅读时所形成的那种理解文本的能力、那种丰富的精神联想(企业库 论坛),在很大程度上都流失掉了。
  
  沃尔夫认为,阅读并非人类与生俱来的技巧,不像说话那样融于我们的基因。我们得训练自己的大脑,让它学会如何将我们所看到的字符译解成自己可以理解的语言。
  
  1882年,尼采买了台打字机。此时的他,视力下降得厉害,盯着纸看的时间长了,动不动头疼得要死,他担心会被迫停止写作。但打字机救了他。他终于熟能生巧,闭着眼睛也能打字——盲打。然而,新机器也使其作品的风格发生了微妙的变化。他的一个作曲家朋友为此写信给他,还说自己写曲子时,风格经常因纸和笔的特性不同而改变。
  
  “您说得对,”尼采复信道,“我们的写作工具渗入了我们思想的形成。”德国媒体学者弗里德里希·基特勒则认为,改用打字机后,尼采的文风“从争辩变成了格言,从思索变成了一语双关,从繁琐论证变成了电报式的风格”。
  
  卡尔引用神经学家的观点,证明成年人的大脑仍然颇具可塑性,而历史上机械钟表和地图的发明,同样说明了人类如何因此改变了对时间与空间的思维。互联网正是今日的钟表与地图。
  
  网络影响让传统媒体也零碎化
  
  当人们的思维方式适应了互联网媒体的大拼盘范式后,传统媒体也会做出改变。电视节目加入了滚动字幕和不断跳出的小广告,报刊则缩短其文章的长度,引入一小块一小块的摘要,在版面上堆砌各种易于浏览的零碎信息。今年3月,《纽约时报》便决定将其第2和第3版改为内容精粹。
  
  Google首席执行官埃里克·施密特说,该公司致力于将“一切系统化”。Google还宣布,其使命是“将全世界的信息组织起来,使之随处可得,并且有用。”通过开发“完美的搜索引擎,”让它能够“准确领会你的意图,并精确地回馈给你所要的东西。”问题是,它会使我们越变越蠢吗?
  
  “我感觉得到。”卡尔最后说,库布里克黑色预言的实质在于:当我们依赖电脑作为理解世界的媒介时,它就会成为我们自己的思想。
  
  上网阅读时,我们充其量只是一台“信息解码器”。
  
  当我们依赖电脑作为理解世界的媒介时,它就会成为我们自己的思想。
