“They do have the cognitive functions that allow them to control their emotions and organize. They’re just not as good at it, during the adolescent years, as they will be during adulthood.”

With advanced brain-imaging technology, researchers have been learning more about how the human brain develops. One mystery experts have explored is why teenagers act the way they do: rebellious, impulsive and too willing to take risks. Now we may have an answer: one part of the adolescent brain is growing too fast, while another is growing too slowly.
Teenagers experiment with drugs. Drive too fast. Get angry and don’t know why.
“Pretty much the rebellion stage started kicking in right about age 12,” recalls Kim, currently 15.
What happens at age 12? According to new research from Temple University, teenagers feel emotions intensely, and care about how other kids feel about them. All that emotion resides in a part of the brain that grows quickly during adolescence. Meanwhile, the rational, careful, thoughtful part of the brain develops more slowly. That imbalance can cause kids to take risks.
“The parts of the brain that continue to develop during adolescence are the parts of the brain that we might expect when we think about typical, negative adolescent behaviors,” says Elizabeth Sowell, Ph.D., neuroscientist, UCLA Dept. of Neurology.
In fact, the study found that when kids were surrounded by other kids while participating in a simulated driving game, they were twice as likely to take risks.
“We know that adolescents are bigger risk takers, we don’t need the brain to tell us that. We know that they get in more car accidents than adults do,” says Sowell.
Experts say the good news is that while it may not be easy to teach teens to avoid risks, it’s not impossible, either.
“They do have the cognitive functions that allow them to control their emotions and organize. They’re just not as good at it, during the adolescent years, as they will be during adulthood,” says Sowell.
Experts say it helps to teach kids to ask themselves a question: ‘if you do this, what are the possible consequences?’ And don’t answer for them.
“Also, it’s much more rewarding for them if they come to the conclusion. Because it’s really coming from their heart and they know that whatever happens, they did the right thing for themselves,” says Diana, 15.
