有了驾驶证,青少年便认为他们能安全驾驶。然而,事情不是像他们想象中那样简单。

With drivers licenses in hand, teens may think theyre safe drivers. But considering how the adolescent brain develops might be a good idea. Young drivers whose brain function falls behind that of their peers are more likely to report having a car crash, according to a new study.

Globally, traffic accidents account for a great proportion in the deaths of adolescents. In the US, for instance, the youngest drivers have the highest rate of crashes and driving?related injuries. “Its a big public health concern,” says Elizabeth Walshe, the research leader from the University of Pennsylvania.

Walshes team followed a group of kids for seven years, starting when they were between the ages of 11 and 13. Every few years, the researchers measured traits linked to having a car crash. At the end, they asked 84 of the participants about their driving experiences, including crashes. Roughly three in ten reported at least one accident.

The researchers focused on the participants working memory. Think of it like a computers random access memory, or RAM. To size up their working memory, the participants took a computer test that measured their reaction time. The scientists found that accident risk wasnt linked to the working memory a participant had at the start of the study. Instead, it was tied to the pace at which a teens working memory developed.

Knowing the relationship between the brains RAM and crash risk is helpful. Walshe imagines teens taking a test in a doctors office. Comparing kids working?memory development to their peers might identify teens at higher risk for an accident. It might point out who could use more assistance during driver training.

Driving is complex. Throughout, the brain is constantly updating information to help a driver plan the next move. “Therere many things that have to be tracked and responded to meanwhile,” notes Monica Luciana, a scientist from the University of Minnesota. With experience, these tasks become more automatic. “Cutting down on distractions(分心) is smart, as this takes some burden off a new drivers working memory,” Luciana says. “Whats more, working memory is a system that can change. And we can influence somebodys ability through training.”
