Talking and driving don't mix

From the The Marois Lab at Vanderbilt University: two researchers are presenting a study aimed at identifying the "bottleneck" in the brain that makes it hard for people to multitask as a reason to avoid talking on a cellphone while driving. "Our new research offers neurological evidence that the brain cannot effectively do two things at once. People think if they are using a headset with their cellphone while driving, they are safe, but they're not, because they are still doing two cognitively demanding tasks at once," said René Marois, an associate professor of psychology at Vanderbilt University in Nashville, Tenn.
