A UI(University of Iowa) study found teenagers are far more sensitive than adults to the immediate effect or reward of their behaviors. The findings may help explain why the initial rush of texting may be more attractive for adolescents than the long?term payoff of studying. “For the teenager, the rewards are attractive，” says Professor Jatin Vaidya, an author of the study. “They draw adolescents. Sometimes, the rewards are a kind of motivation for them. Even when a behavior is no longer in a teenager’s best interest to continue, he will still go on. That’s because the effect of the reward is still there and lasts much longer in adolescents than in adults.” For parents, that means limiting distraction so teenagers can make better choices. Take the homework and social media dilemma for example: At 9 p．m., shut off everything except a computer that has no access to Facebook or Twitter, the researchers advise. “I’m not saying they shouldn’t be allowed to have access to technology，” Vaidya says. “But some help in netting their concentration is necessary for them so they can develop those impulse(冲动)?control skills.” In their study, Vaidya and co?author Shaun Vecera note researchers generally believe teenagers are impulsive, make bad decisions, and engage in risky behavior because the frontal lobes(额叶) of their brains are not fully developed. But the UI researchers wonder whether something more fundamental is going on with adolescents to cause behaviors independent of higher?level reasoning. “We wanted to try to understand how the brain’s reward system changes from childhood to adulthood，” says Vaidya, who adds the reward character in the human brain is easier than decision?making. “We’ve been trying to understand the reward process in adolescence and whether there is more to adolescence behavior than an underdeveloped frontal lobe，” he adds. For their study, the researchers persuaded 40 adolescents, aged 13 and 16, and 40 adults, aged 20 and 35 to participate. In the future, researchers hope to look into the psychological and neurological aspects of their results. 1．What does the passage mainly tell us? A．Always, rewards are attractive to teenagers.
