The gift of being able to describe a face accurately is a rare one. As a professor <u> <u> 1 </u> </u> it recently: "When we try to describe faces precisely words <u> <u> 2 </u> </u> us, and we <u> <u> 3 </u> </u> to identikit (拼脸型图) procedures."
<u> <u> 4 </u> </u> according to a research <u> <u> 5 </u> </u> this subject, we can each probably recognize more than 1,000 faces, the majority of which differ in <u> <u> 6 </u> </u> details. This, when one comes to think of it, is a<u> <u> 7 </u> </u> feat, though, curiously enough, relatively little attention has been devoted to the fundamental problems of how and why we <u> <u> 8 </u> </u> this gift for recognizing and remembering faces.
Some scientists argue that it is an inborn <u> <u> 9 </u> </u>. and that there are "special characteristics about the brain's <u> <u> 10 </u> </u> to distinguish faces". On the other hand, there are those, and they are probably <u> <u> 11 </u> </u> the majority, who claim that the gift is an acquired one.
But <u> <u> 12 </u> </u> all these arguments, sight is predominant. <u> <u> 13 </u> </u> at the very beginning of life, the ability to recognize faces quickly becomes an <u> <u> 14 </u> </u> habit, one that is essential for daily living, if not <u> <u> 15 </u> </u> for survival. How essential and valuable it is we probably do not <u> <u> 16 </u> </u> until we encounter people who have been <u> <u> 17 </u> </u> of the faculty (能力). This unfortunate inability to recognize familiar faces is known to all, <u> <u> 18 </u> </u> such people can often recognize individuals by their voices or their walking manners. With typical human <u> <u> 19 </u> </u> many of these unfortunate people overcome their handicap by recognizing other <u> <u> 20 </u> </u> features.
