Politico:Lawmakers all a-Twitter
Twitter Hall
Dividing, or even diverting, your attention has other costs as well, said Dave Crenshaw, author of “The Myth of Multitasking,” who explained that anytime someone goes back and forth between two tasks, there’s a “switching cost” to be paid — that is, the amount of time and effort it takes to get back on track.
“Let’s say that I’m listening to someone speak in Congress and I pause to type something on Twitter,” he said. “The actual typing may take me 30 seconds, but the actual loss of my attention may be 5 to 10 minutes. So the cost is greater than the activity.”
