Spending more time at school may increase intelligence, according to a study of Norwegian men, BBC reported.

The research, in Proceedings of the National Academy of Sciences, suggested that an extra year in the classroom could boost IQ by nearly four points.

The authors said that extra schooling had a "sizeable effect" on IQ in early adulthood.

But they do not know if this applies to all children, or just those in this study.

據(jù)英國廣播公司報道，對挪威男性的一項研究表明，學(xué)校呆的時間越長就越可能會提高智商。

該研究刊登在《國家科學(xué)研究院學(xué)報》。研究稱，在教室多學(xué)習(xí)一年就可以提高智商近4個點。

該研究作者稱，剛進(jìn)入成年期時，在學(xué)校額外呆的時間對智商有很大的影響。

但是，他們尚不知這是否對每個孩子都適用，或者僅限于此次的研究對象。
