Geniuses are getting brighter. And at genius levels of IQ, girls are not as far behind boys as they used to be.
SCIENCE has few more controversial topics than human intelligence—in particular, whether variations in it are a result of nature or nurture, and especially whether such variations differ between the sexes. The mines in this field can blow up an entire career, as Larry Summers found out a few years ago when he spoke of his hypothesis. What he found is that the mathematical aptitude needed for physics and engineering, as well as for maths itself, is rarer in women than in men. He resigned as president of Harvard University shortly afterwards.
It is bold, therefore, of Jonathan Wai, Martha Putallaz and Matthew Makel, of Duke University in North Carolina, to enter the controversy with a paper that addresses both questions. In this paper, just published in Current Directions in Psychological Science, they describe how they picked out through nearly three decades of standardized tests administered to American high-school students to see what had been happening to the country’s brightest sparks.
They drew two conclusions. One is that a phenomenon called the Flynn effect applies in particular to the brightest of the bright. The other is that part, but not all, of the historic difference between the brainiest men and women has vanished.
The three researchers drew their data from Duke University’s Talent Identification Program, TIP, which is designed to pick out especially clever candidates early on: all the participants had scored in the top 5% of ability when confronted with exams designed for much older students. TIP, in turn, draws on three national exams: SAT, EXPLORE and ACT. Altogether, Dr. Wai, Dr. Putallaz and Dr. Makel looked at data from 1.7 million children.
In the general population boys are well known to do a bit better than girls in maths. Girls, in turn, edge out boys on tests of verbal reasoning. The result is similar overall IQ scores. Among the best young mathematical brains, however, the equality is not appropriate. Here, boys do a lot better at maths than girls—but less better than they used to, as the researchers discovered.
19 What did Larry Summers find out?
20 What is the second conclusion drawn in the paper by three researchers?
21 What did the researchers discover about the best young mathematical brains?
选项
A、Boys have the same intelligence as the most intelligent girls.
B、Boys have a great advantage in the test of verbal reasoning.
C、IQ difference between the sexes is increasing little by little.
D、Boys are better at math than girls but the gap is narrowing.
答案
D
解析
录音最后指出在数学方面男生比女生要优秀得多,但是研究者发现男生的这种优势已经比以前小了,故D正确。
