Having a teenager at home can be a real
headache. Many teenagers smoke, drink and even fight. They often do something
dangerous.
Earlier studies have shown that teenagers
are more likely(可能) to make irrational
decisions than people from any other age group, including children and adults.
Is it that teenagers are too young to tell right from wrong? Not really. So
what's the reason?
According to Laurence, a teacher from a US
university, the reason is that teenagers care a lot about how their peers(年龄) view them--that is "peer influence".
As children enter their teenage years, they
spend more time with their friends and classmates, and also they care more
about what they think of them. This makes teenagers make decisions without
thinking about the costs.
In a test, a group of teenagers were asked
to play a video driving game. When they played with their friends watching
around them, they took more chances and drove more carelessly because that
would increase their possibility of winning. But when they played alone, they
drove more safely.
Why do peers have such a big influence on
teens' behavior?
As Laurence sees it, a teenager's brain is
like a car with a good accelerator(油门) but a
weak brake(刹车). The "accelerator" is fully
developed by teenage years while the "brake" is still not fully developed.
When teenagers are watched by their peers, they usually push hard on the
accelerator. With their weak brake, it is likely that they are going to end up
in an accident.
But the good news is that a violent(暴力) teenager doesn't necessarily become a violent adult. About
two-thirds to three-quarters of violent youth grow out of it. "They get
more self-controlled."
