Multitasking, revisited

In my December 2 post I wondered about the appropriate role of mobile devices in the classroom. Since writing that column, I’ve discovered four relevant references that may influence one’s thinking on the issue.

1. PBS Frontline, “Digital Nation” (February 2, 2010, Season 28, Episode 3, What is the effect of media multitasking on society, education, brain development, and the economy? Interviews with researchers reveal what we now know about how badly the human brain multitasks and how some multitasking is impairing our ability to think deeply, even after the computer is turned off. In light of this research, the documentary challenges conventional wisdom about the role of technology in the classroom, yet perhaps most intriguing is the coverage of a Stanford study (see #2).

2. Ophir, Nass and Wagner, “Cognitive Control of Media Multitaskers” (Proceedings of the National Academy of Sciences, 2009, vol. 106, no. 37). This study shows that students who think they are highly effective multitaskers are actually quite the opposite, or as Stanford’s Clifford Nass said in a BBC interview: “The shocking discovery of this research is that [high multitaskers] are lousy at everything that’s necessary for multitasking.” See additional coverage in Wired Magazine and The Associated Press.

3. Maggie Jackson, Distracted: The Erosion of Attention and the Coming Dark Age (Prometheus Books, 2008). Jackson is another who argues that despite the cultural acceptance of multitasking, such practices are undermining our own attention skills; she cites more scientific studies that suggest that we have become so distracted by multitasking that we are losing the ability to think deeply about problems. In a video interview posted on her website (, she asks,

What are the repercussions for a democracy when citizens are surrounded by information and are less and less capable of creating knowledge or learning from that information?

Jackson says that the average knowledge-based worker in the US now switches tasks every three minutes, and about half of these are interrupting. If you are wondering about the financial toll of all this multitasking and disruption, you may be interested in this…
