Fascinating feature in New York Magazine about how we are dealing with all these technologies that require constant attention and apparently we are not very good at multi-tasking
Over the last twenty years, Meyer and a host of other researchers have proved again and again that multitasking, at least as our culture has come to know and love and institutionalize it, is a myth. When you think you’re doing two things at once, you’re almost always just switching rapidly between them, leaking a little mental efficiency with every switch. Meyer says that this is because, to put it simply, the brain processes different kinds of information on a variety of separate “channels”—a language channel, a visual channel, an auditory channel, and so on—each of which can process only one stream of information at a time. If you overburden a channel, the brain becomes inefficient and mistake-prone. The classic example is driving while talking on a cell phone, two tasks that conflict across a range of obvious channels: Steering and dialing are both manual tasks, looking out the windshield and reading a phone screen are both visual, etc. Even talking on a hands-free phone can be dangerous, Meyer says. If the person on the other end of the phone is describing a visual scene—say, the layout of a room full of furniture—that conversation can actually occupy your visual channel enough to impair your ability to see what’s around you on the road.
The only time multitasking does work efficiently, Meyer says, is when multiple simple tasks operate on entirely separate channels—for example, folding laundry (a visual-manual task) while listening to a stock report (a verbal task). But real-world scenarios that fit those specifications are very rare.
But why do we have this urge to do multiple things?
I’m not ready to blame my restless attention entirely on a faulty willpower. Some of it is pure impersonal behaviorism. The Internet is basically a Skinner box engineered to tap right into our deepest mechanisms of addiction. As B. F. Skinner’s army of lever-pressing rats and pigeons taught us, the most irresistible reward schedule is not, counterintuitively, the one in which we’re rewarded constantly but something called “variable ratio schedule,” in which the rewards arrive at random. And that randomness is practically the Internet’s defining feature: It dispenses its never-ending little shots of positivity—a life-changing e-mail here, a funny YouTube video there—in gloriously unpredictable cycles. It seems unrealistic to expect people to spend all day clicking reward bars—searching the web, scanning the relevant blogs, checking e-mail to see if a co-worker has updated a project—and then just leave those distractions behind, as soon as they’re not strictly required, to engage in “healthy” things like books and ab crunches and undistracted deep conversations with neighbors. It would be like requiring employees to take a few hits of opium throughout the day, then being surprised when it becomes a problem. Last year, an editorial in the American Journal of Psychiatry raised the prospect of adding “Internet addiction” to the DSM, which would make it a disorder to be taken as seriously as schizophrenia.
The most promising solution seems to be meditation to get your executive attention control in shape
The most promising solution to our attention problem, in Gallagher’s mind, is also the most ancient: meditation. Neuroscientists have become obsessed, in recent years, with Buddhists, whose attentional discipline can apparently confer all kinds of benefits even on non-Buddhists. (Some psychologists predict that, in the same way we go out for a jog now, in the future we’ll all do daily 20-to-30-minute “secular attentional workouts.”) Meditation can make your attention less “sticky,” able to notice images flashing by in such quick succession that regular brains would miss them. It has also been shown to elevate your mood, which can then recursively stoke your attention: Research shows that positive emotions cause your visual field to expand. The brains of Buddhist monks asked to meditate on “unconditional loving-kindness and compassion” show instant and remarkable changes: Their left prefrontal cortices (responsible for positive emotions) go into overdrive, they produce gamma waves 30 times more powerful than novice meditators, and their wave activity is coordinated in a way often seen in patients under anesthesia.
Gallagher stresses that because attention is a limited resource—one psychologist has calculated that we can attend to only 110 bits of information per second, or 173 billion bits in an average lifetime—our moment-by-moment choice of attentional targets determines, in a very real sense, the shape of our lives. Rapt’s epigraph comes from the psychologist and philosopher William James: “My experience is what I agree to attend to.” For Gallagher, everything comes down to that one big choice: investing your attention wisely or not. The jackhammers are everywhere—iPhones, e-mail, cancer—and Western culture’s attentional crisis is mainly a widespread failure to ignore them.
Author suggests that some of the predictions associated with the attention problem might be overblown and may be our brains will just adapt to the new stimulus environment…I am not sure but I hope certainly that we can cope.
