Multi-taskers might seem super-human, but they pay a big price, according to a 2009 Stanford study. In a sample of 100 Stanford students, abut half identified themselves as media multitaskers. The other half did not.
The test examined attention spans, memory capacity, and ability to switch from one task to the next — and the multitaskers performed more poorly or each test.
"They're suckers for irrelevancy. Everything distracts them," Clifford Nass, who was a researcher for the study, said in a Stanford press release.
