     The gift of being able to describe a face accurately is a rare one, as every experienced police

officer knows to his cost. As the Lancet put it recently, "When we try to describe faces precisely,

words fail us, and we resort to identikit (拼脸型图) procedures."

     Yet, according to one authority on the subject, we can each probably recognize more than

1,000 faces, the majority of which differ in fine details. This, when one comes to think of it, is a

tremendous feat, though, curiously enough, relatively little attention has been devoted to the

fundamental problems of how and why we acquire this gift for recognizing and remembering faces.

Is it an inborn property of our brains, or an acquired one? As so often happens, the experts tend

to differ.

     Thus, some argue that it is inborn, and that there are "special characteristics about the brain's

ability to distinguish faces". In support of this, they note how much better we are at recognizing a

face after a single encounter than we are, for example, in recognizing an individual horse. On the

other hand, there are those, and they are probably in the majority, who claim that the gift is an

acquired one.

     The arguments in favor of this latter view, it must be confessed, are impressive. It is a habit that

is acquired soon after birth. Watch, for instance, how a quite young baby recognizes his mother by

sight. Granted that his other senses help - the sound, his sense of smell, the distinctive way she

handles him. But of all these, sight is predominant. Formed at the very beginning of life, the ability

to recognize faces quickly becomes an established habit, and one that is, essential for daily living,

if not necessarily for survival. How essential and valuable it is we probably do not appreciate until

we encounter people who have been deprived of the faculty.

     This unfortunate inability to recognize familiar faces is known to all, but such people can often

recognize individuals by their voices, their walking manners or their spectacles. With typical human

ingenuity, many of these unfortunate people overcome their handicap by recognizing other

characteristic features.

A. It is one of the characteristics peculiar to human beings.

B. It is acquired soon after birth.

C. It is something we can do from the very moment we are born.

D. It is learned from our environment and experiences.
