“While the testimonials of digital literacy enthusiasts are replete with abstract paeans to the possibilities presented by screen reading, the experience of those who do it for a living paints a very different picture. Just as Griswold and her colleagues suggested the impending rise of a “reading class,” British neuroscientist Susan Greenfield argues that the time we spend in front of the computer and television is creating a two-class society: people of the screen and people of the book. The former, according to new neurological research, are exposing themselves to excessive amounts of dopamine, the natural chemical neurotransmitter produced by the brain. This in turn can lead to the suppression of activity in the prefrontal cortex, which controls functions such as measuring risk and considering the consequences of one’s actions.Writing in The New Republic in 2005, Johns Hopkins University historian David A. Bell described the often arduous process of reading a scholarly book in digital rather than print format: “I scroll back and forth, search for keywords, and interrupt myself even more often than usual to refill my coffee cup, check my e-mail, check the news, rearrange files in my desk drawer. Eventually I get through the book, and am glad to have done so. But a week later I find it remarkably hard to remember what I have read.”

As he tried to train himself to screen-read—and mastering such reading does require new skills—Bell made an important observation, one often overlooked in the debate over digital texts: the computer screen was not intended to replace the book. Screen reading allows you to read in a “strategic, targeted manner,” searching for particular pieces of information, he notes. And although this style of reading is admittedly empowering, Bell cautions, “You are the master, not some dead author. And that is precisely where the greatest dangers lie, because when reading, you should not be the master”; you should be the student. “Surrendering to the organizing logic of a book is, after all, the way one learns,” he observes.

How strategic and targeted are we when we read on the screen? In a commissioned report published by the British Library in January 2008 (the cover of which features a rather alarming picture of a young boy with a maniacal expression staring at a screen image of Darth Vader), researchers found that everyone, teachers and students alike, “exhibits a bouncing/flicking behavior, which sees them searching horizontally rather than vertically….Users are promiscuous, diverse, and volatile.” As for the kind of reading the study participants were doing online, it was qualitatively different from traditional literacy. “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.” As the report’s authors concluded, with a baffling ingenuousness, “It almost seems that they go online to avoid reading in the traditional sense.”

Aha! Here’s the real reason for the financial crash! Glued to their computer trading screens, all those “quants” and geeks who bundled up risk into little packages and shot them across the globe in a viral campaign addled their pre-frontal lobes. More seriously, computer interaction does encourage a kind of virtual reality of quick response, immediate gratification, high-wire devilry and flaring tempers.

Examples:

The Internet porn industry has higher levels of addiction than off-line porn.

Video games are used by the Department of Defense to desensitize potential recruits. Popular games like Grand Theft Auto, for instance, allow players to mimic and experience criminal activity.

Online addiction is even categorized by some people as a separate category of compulsive behavior. Whether that’s excessive or not, it’s true that what’s on our screen affects us in a quite different way than what’s on a printed page. And that’s why one of the best ways to counter government control of the web is to practice a little self-restraint in posting on it.
