Something we all knew but didn't want to believe: multitaskers are better at nothing.
Think you can talk on the phone, send an instant message and read your e-mail all at once? Stanford researchers say even trying may impair your cognitive control.
Attention, multitaskers (if you can pay attention, that is): Your brain may be in trouble.
People who are regularly bombarded with several streams of electronic information do not pay attention, control their memory or switch from one job to another as well as those who prefer to complete one task at a time, a group of Stanford researchers has found.High-tech jugglers are everywhere – keeping up several e-mail and instant message conversations at once, text messaging while watching television and jumping from one website to another while plowing through homework assignments.
But after putting about 100 students through a series of three tests, the researchers realized those heavy media multitaskers are paying a big mental price.
“They're suckers for irrelevancy,” said communication Professor Clifford Nass, one of the researchers whose findings are published in the Aug. 24 edition of the Proceedings of the National Academy of Sciences. “Everything distracts them.”
Social scientists have long assumed that it's impossible to process more than one string of information at a time. The brain just can't do it. But many researchers have guessed that people who appear to multitask must have superb control over what they think about and what they pay attention to.
…So Nass and his colleagues, Eyal Ophir and Anthony Wagner, set out to learn what gives multitaskers their edge. What is their gift?
“We kept looking for what they're better at, and we didn't find it,” said Ophir, the study's lead author and a researcher in Stanford's Communication Between Humans and Interactive Media Lab.
