Stop, focus and read

Long before it was called "multitasking," researchers have been looking at just how well people can do two things at once. An article in The Chronicle of Higher Education gives a fascinating — and for many folks, counterintuitive — update. More than 100 years ago, the Industrial Age saw young factory workers rolling cigars while listening to books, newspapers and political or religious tracts being read aloud; the Tech Age finds today's college student sending text-messages in class while listening to the lecture, watching a PowerPoint with imbedded videos, taking notes and googling facts in anticipation of the professor's questions.

The multimedia experience, conventional wisdom tells us, enhances learning as it "lights up" more parts of the brain, but now it appears that people may be merely buzzed by over stimulation.

"Heavy multitaskers are often extremely confident in their abilities," Clifford I. Nass, a professor of psychology at Stanford University, told The Chronicle. "But there's evidence that those people are actually worse at multitasking than most people."

Nass and colleagues published a study in 2009 revealing that people who described themselves as multitaskers performed much worse on tests of cognition and memory that involved distraction than their counterparts who said they preferred to focus on single tasks. And a newer, as-yet-unpublished study by Nass, et al., shows that people who give a lot of time over to media screens fare worse on analytic questions, too.

"One of the deepest questions in this field," Nass says, "is whether media multitasking is driven by a desire for new information or by an avoidance of existing information. Are people in these settings multitasking because the other media are alluring — that is, they're really dying to play Freecell or read Facebook or shop on eBay — or is it just an aversion to the task at hand?"

So glad you dropped by to read this post — hope it didn't distract you for too long from your other tasks!
