You Asked: Are My Devices Messing With My Brain?

Yes—and you’re probably suffering from phantom text syndrome, too.

First it was radio. Then it was television. Now doomsayers are offering scary predictions about the consequences of smartphones and all the other digital devices to which we’ve all grown so attached. So why should you pay any attention to the warnings this time?

Apart from portability, the big difference between something like a traditional TV and your tablet is the social component, says Dr. David Strayer, a professor of cognition and neural science at the University of Utah. “Through Twitter or Facebook or email, someone in your social network is contacting you in some way all the time,” Strayer says.

“We’re inherently social organisms,” adds Dr. Paul Atchley, a cognitive psychologist at Kansas University. There’s almost nothing more compelling than social information, he says, which activates part of your brain’s reward system. Your noodle is also hardwired to respond to novel sights or sounds. (For most of human history, a sudden noise might have signaled the presence of a predator.) “So something like a buzz or beep or flashing light is tapping into that threat detection system,” he explains.

Combine that sudden beep with the implicit promise of new social info, and you have a near-perfect, un-ignorable stimulus that will pull your focus away from whatever task your brain is working on. And while you may think you can quickly check a text or email and pick up that task where you left off, you really can’t.

“Every time you switch your focus from one thing to another, there’s something called a switch-cost,” says Dr. Earl Miller, a professor of neuroscience at Massachusetts Institute of Technology. “Your brain stumbles a bit, and it requires time to get back to where it was before it was distracted.”
