時(shí)差N小時(shí):永遠(yuǎn)記住面孔?

Remembering Faces Forever? Are you good atremembering faces? How about the face of astranger you passed in the supermarket aisle threemonths ago? Or the face of a waitress who servedyou dinner last year? That may seem unlikely, butsome people are what's known as “superrecognizers.”

永遠(yuǎn)記住面孔?你很擅長(zhǎng)記住面孔?那你還記得三個(gè)月前在超市走道上碰見的陌生人的長(zhǎng)相嗎?或者是去年為你點(diǎn)過晚餐的服務(wù)員的長(zhǎng)相?也許顯得很不靠譜，但的確有人是所謂的“超級(jí)識(shí)別者”。

They can instantly recognize faces they glimpsed months and even years ago. This isinteresting because it suggests that face recognition exists on a broad spectrum. Previously,scientists thought that people fall into two basic categories. Most people have more or less thesame, average ability for recalling faces.

他們能夠立刻辨認(rèn)出幾個(gè)月甚至幾年前瞥過一眼的面孔。這個(gè)現(xiàn)象很有趣，因?yàn)檫@表明面部識(shí)別的范疇是廣泛的。很明顯，科學(xué)家們認(rèn)為人可分為兩類。大多數(shù)人在記憶面孔的能力方面大抵相同。

But around two percent of people can hardly recognize faces at all—a condition calledprosopagnosia. The discovery that a small percentage of people are super recognizers means theoverall spectrum of face recognition is more expansive than we knew. While relatively fewpeople fall into either extreme, most of us exist somewhere in between.

但是有2%的人根本辨認(rèn)不出臉孔——這種情況叫做面容失認(rèn)癥。同時(shí)還發(fā)現(xiàn)一小部分人是超級(jí)面部辨認(rèn)者，這意味著辨認(rèn)面孔的整體頻譜比我們知道的更為廣泛。然而，相對(duì)來說屬于這兩種范疇的人很少，大多數(shù)人都是介于這兩者之間。

But that doesn't mean that most people are equally competent at recognizing faces. Withoutbeing a super recognizer, Joe may exist somewhere in the neighborhood of strong facial recall.Whereas Jane's talent for remembering faces might lie closer to the prosopagnosia end ofthings.

但是，那并不意味著大多數(shù)人在辨認(rèn)面孔的能力方面是一樣的。喬不是一個(gè)超級(jí)面孔識(shí)別者，當(dāng)他出現(xiàn)在一個(gè)辨認(rèn)面孔整體水平很強(qiáng)的社區(qū)時(shí)，就顯得像得了人面失認(rèn)癥。

For the most part, where you fall on the face recognition spectrum may not matter. But if,say, you're an eyewitness in a murder trial, then your relative ability for recalling faces mightbecome a pivotal fact in the trial.

就絕大部分而言，你屬于哪個(gè)范圍并不要緊。然而，萬一你是一樁犯罪案件的目擊者，那么你識(shí)別面孔的能力就是審判的關(guān)鍵所在了。
