60秒科学:Listening While Driving Is, What'd Ya Say?

Listening While Driving Is, What'd Ya Say?
A study in the journal Psychonomic Bulletin and Review finds that not only does talking interfere¹ with driving skills, the act of driving makes listening a much harder task. Karen Hopkin reports

We all know that talking on a cell phone can impair² our ability to drive (although too many of us do it anyway). Now a study in the journal Psychonomic Bulletin and Review shows that the reverse is also true: driving makes it hard to keep track of what we’re talking about.

Previous studies had found that motorists are able to converse³ just fine. But to Gary Dell of the University of Illinois that finding just didn’t make sense. Because comprehending speech requires attention, as does steering⁴ the family sedan. So Dell did a study in a driving simulator.

Ninety-six participants were paired up, with one taking the wheel while the other sat in the passenger seat or talked to the driver on a hands-free phone. Each participant listened to and was asked to repeat a handful of stories, and then to remember them after getting out of the car. As you can imagine, the drivers had a tougher time recalling the details than the passengers. And their conversational⁵ skills took the biggest nosedive while they were trying to navigate⁶ intersections⁷ or handle traffic.

Next, maybe the scientists will determine whether driving also impairs⁸ our ability to sing, eat breakfast, and put on makeup⁹. And, of course, text.
