PHILADELPHIA, Pa. (Ivanhoe Newswire) -- Neuroscientists studying the teenage brain say that when a teen is surrounded by peers, he or she is more likely to push the boundaries and take chances. Researchers say there may be some steps parents and their teens can take to reduce risk-taking behavior.

It’s no surprise to Jason Chein, PhD, a cognitive neuroscientist at Temple University in Philadelphia. Researchers at Temple University’s Brain Research and Imaging Center monitored teens while performing a computerized stoplight task. Teens had to drive a car on a straight stretch of roadway and decide whether or not to stop at a yellow light. The goal was to finish the course as fast as possible, while trying not to crash. Researchers used the intercom to tell teens they had friends nearby watching and making predictions about their performance. During the task, researchers saw activation in two regions of the teens’ brains that process rewards.
“In and of itself it says to parents even a good teen, even a smart teen that has good information about their behavior is likely to behave differently when they’re in the presence of their friends or when they think they’re in a social environment,” explained Chein.
Temple scientists also had teens aged 13 to 17 complete memory training every day for one month and found those teens took fewer risks when being watched by their peers. Chein said it’s possible memory training might help teens with self-regulation.
Chein told Ivanhoe, “They’re still waiting for their cognitive control systems to come online. But we might be able to give that system a boost.”
Professor Chein said the results of the Temple study are preliminary. He says parents should make sure they know their kid’s friends and try to limit their opportunities to engage in reckless behavior.
