Mr. Nass says the Stanford studies are important because they show multitasking’s lingering effects: “The scary part for guys like Kord is, they can’t shut off their multitasking tendencies when they’re not multitasking.”
Melina Uncapher, a neurobiologist on the Stanford team, said she and other researchers were unsure whether the muddied multitaskers were simply prone to distraction and would have had trouble focusing in any era. But she added that the idea that information overload causes distraction was supported by more and more research.
A study at the University of California, Irvine, found that people interrupted by e-mail reported significantly increased stress compared with those left to focus. Stress hormones have been shown to reduce short-term memory, said Gary Small, a psychiatrist at the University of California, Los Angeles.
