四川省眉山市仁寿县校联考2023-2024学年九年级上学期11月期中英语试题
Some people are very careful about everything they do. On the other hand, some people, especially teens, do things without thinking too much about the results. Why is this?
Anna, a psychologist uses computer games to find out why some people are more likely to take risks. In one game, players are asked to click(点击) on a balloon on a computer screen. Every time they click, the balloon gets bigger. The bigger the balloon is, the larger the prize will be. But if the balloon gets too big, it'll be broken and the player will get nothing.
Anna found that when teens played this game, a part of their brain called the striatum (纹状体) would become more active. It makes teens want to win. Another part of the brain, the prefrontal cortex (前额皮质), helps them control their decision-making process.
It turns out that young people have more striatums and less prefrontal cortexes, which affects their ability to make careful decisions. You might have already guessed that teens break more balloons during the game than adults – mainly because they like to take risks more and don't take the time to think carefully.
"The teen brain is like a car with a very strong engine, " Anna said. "Its brakes (刹 车) just don't work as well. "
