Multitasking

From "The Autumn of the Multitaskers" by Walter Kirn, The Atlantic Monthly, November 2007

It isn’t working, it never has worked, and though we’re still pushing and driving to make it work and puzzled as to why we haven’t stopped yet, which makes us think we may go on forever, the stoppage or slowdown is coming nonetheless, and when it does, we’ll be startled for a moment, and then we’ll acknowledge that, way down deep inside ourselves (a place that we almost forgot even existed), we always knew it couldn’t work.

The scientists know this too, and they think they know why. Through a variety of experiments, many using functional magnetic resonance imaging to measure brain activity, they’ve torn the mask off multitasking and revealed its true face, which is blank and pale and drawn.

Multitasking messes with the brain in several ways. At the most basic level, the mental balancing acts that it requires—the constant switching and pivoting—energize regions of the brain that specialize in visual processing and physical coordination and simultaneously appear to shortchange some of the higher areas related to memory and learning. We concentrate on the act of concentration at the expense of whatever it is that we’re supposed to be concentrating on.
