Why is driving while talking on a cellphone so dangerous? American researchers have shown that language interferes with visual tasks and why speaking is more taxing on the brain than listening.
"It's really an attention problem, not really about holding the phone in your hand," said Dr. Amit Almor, an associate professor of psychology at the University of South Carolina.
Almor and his colleague Tim Boiteau, who measured attention levels in 94 people, found that talking or preparing to speak was four times more distracting than listening.
"People can tune in or out as needed when listening," said Almor.
In the studies the participants were asked to perform visual tasks such as tracking a fast-moving target across a computer screen with a mouse, while listening to pre-recorded narratives and then responding. The voice would also shift around the room, either front, back or side to side.
