单选题John Hewitt studies the biology of intelligence. He"s also a parent. Over the years, Hewitt has drawn on his scientific knowledge in making parenting decisions. "I"m a father of four children myself. I never worried too much about the environments that I was providing for my children, because I thought it would all work out in the end anyway—aren"t the genes especially powerful?" Hewitt says. He knew intelligence has a strong biological part. If your parents are smart, you"ll probably be smart. But recently, Hewitt discovered something that surprised him. "Well, I may have been wrong," he admits. "It is the environmental increase you can get, or the harm you can suffer through hard times that may be a little more important in adolescence (青春期) than I had thought." Hewitt and other researchers recently noticed that kids who had a higher IQ to begin with seemed to have an extended period in adolescence during which they kept the ability to learn at a rapid pace, just like much younger children. "It was as if there was an extended sensitive period in the higher IQ individuals. Or another way of looking at it is that the sensitivity to the environment which is characteristic of earlier childhood seems to end earlier for individuals with a lower IQ," Hewitt says. "Smart kids may tend to take part in challenging activities and this keeps them ready to consider learning. Or it could be that lead to high IQ, which also causes an extended learning period". An extended learning period does not necessarily mean a further increase in the IQ. But a very smart teenager with an extended "sensitive period" of learning might be able to pick up a new language or a musical instrument. Such learning can have long-term benefits. "Even if in the end IQ ends up being determined to a large extent by the genes, if there"s been a period where the environment makes a difference, that could have lifelong consequences," Hewitt says.
