The researchers compared the test results of one hundred seven thousand young men to their years of school. Taryn Ann Galloway is a researcher at the University of Oslo.
研究人员把10.7万青年男子的测试结果和他们的上学时间做了一个比较。泰伦·安·加洛韦是奥斯陆大学一名研究人员。
TARYN ANN GALLOWAY: "The young men who were basically forced to stay in school for two years longer actually did have higher IQs. So, based on that, we were able to say that increasing compulsory schooling did actually have an effect on their cognitive abilities as measured at nineteen years of age."
加洛韦:“被迫在学校多待了两年的青年男子智商确实更高。所以在此基础上,我们可以说,以19岁时的认知能力来衡量,增加义务教育确实对此有影响”.
