你的朋友會改變你的智商

Researchers from Berlin analysed the characteristics of a number of genes among a group of healthy adolescents, and compared the results with intelligence scores and various neurological traits.

柏林的一些研究者研究了一組健康青年人的人格特征，并把這些結(jié)果和智商以及各種神經(jīng)學(xué)特征進(jìn)行了比較。

The researchers found a strong relationship between the epigenetic modifications of one particular gene and general IQ, suggesting our experiences not only affect the wiring of our brain, but the very way our genes function at a basic level.

研究者們發(fā)現(xiàn)，有一個基因上發(fā)生的后天變異可以影響我們的整體智商，這說明我們的經(jīng)歷不光會影響大腦的運(yùn)行，還會從基因?qū)用嬗绊懘竽X運(yùn)作的原理。

For example, in times of high stress, such as a persistent threat of violence or poor nutrition, physiological changes in the organism can tweak your genes by adding or removing a chemical group that effectively locks them down or opens them up.

比如，在你遭受高水平壓力的時候，比如長期暴露于暴力威脅或營養(yǎng)缺乏之下，你身體發(fā)生的生理性變化就會對你的基因進(jìn)行微調(diào)，他們會增加或移除一些化學(xué)物質(zhì)，而這些物質(zhì)的存在與否決定了一些基因的表達(dá)與否。

These edits can also go the other way. It's possible that showing infants ample affection, such as frequent cuddles, just might modify the expression of their genes in the same way.

這個過程也可以從相反的方向起效果。如果你讓嬰兒體會到足夠的愛，比如經(jīng)常得到擁抱，也可能對他們的基因表達(dá)起到影響。

In turn, such changes can subtly influence a range of characteristics that can have drastic knock-on effects, altering the course of everything from how your immune system functions to how much you earn.

這些改變會對一系列行為特征起到微妙的影響，而這一系列連帶反應(yīng)最終能讓你發(fā)生驚人的改變，比如影響你的免疫系統(tǒng)的運(yùn)作方式，或者決定你能賺多少錢。
