You know those people who always run into people they know? Like when they're buying groceries, taking the kids to school, trying on jackets? They must be really popular, right?
身邊有沒有朋友總是能碰巧遇見熟人？比如當他們在購買食品、送孩子去上學或者試穿夾克的時候？他們肯定人緣很好，對嗎？
Well maybe not.
那可不一定了。
Maybe they just have a talent for spotting and recognizing faces. Because there are also those who couldn’t recognize Angelina Jolie if she got a perm.
也許他們只是有發現和識別臉部特征的天賦。因為總有人會因為安吉麗娜朱莉燙了頭發，就認不出她來。
Well research published in this month's Current Biology finds that the ability to recognize faces is most likely heritable, and the research also supports the so-called modular view of the brain.
《現代生物學》發表的最近一篇論文指出，人的面部識別能力很可能是遺傳的。研究也支持所謂的大腦“模塊化”觀點。
This is the view that the brain acts more like a toolbox with different specialties, as opposed to a generalized piece of equipment. This generalist theory is what the idea of IQ is based on—meaning that an aptitude for math probably means an aptitude for reading, too.
這種觀點認為大腦的運轉更像是一個有著不同功能的工具箱，而不是廣義的一件設備。這種通才理論就是IQ說法建立的基礎，他們認為一個數學資質好的人，可能同時也擅長閱讀。
The researchers had 102 pairs of identical twins and 71 pairs of fraternal twins look at 20 different images of faces for about a second each. Then 10 of the images were mixed with 20 new face images. Subjects had to say which ones they’d already seen.
研究人員讓102同卵雙胞胎和71對異卵雙胞胎看20張不同面孔的圖像，每張展示1秒鐘。然后將其中的10張與20張新面孔的圖像混合在一起。測試者需要指出哪些圖像是他們看過的。
And scores were significantly more matched between identical as opposed to fraternal twins. The researchers controlled for differences in vision, general object recognition and memory.
同卵雙胞胎之間的辨認結果比異卵雙胞胎的相似得多。研究人員通過控制實驗，測試他們在視覺、總體物體識別和記憶上的差別。
In a separate study with 320 participants they also found that facial recognition ability was independent of IQ. According to the researchers, these findings support the view that there are specialist genes that specifically affect a talent for face recognition.
在另外一項有320名志愿者參與的研究中，他們同樣發現了面部識別能力與IQ無關。他們認為，這些發現證實了面部識別能力受特殊基因影響的觀點。
They write that this heritability of specific cognitive talents might suggest that some genes have specific cognitive effects, and that this research might give insight into disorders like dyslexia or Williams syndrome.
他們撰文道，這種有遺傳性的特殊認知能力可能顯示某種基因能影響特殊的識別能力，同時，這項研究也將有助于誦讀困難癥和威廉斯綜合癥的治療。
