    A scientist turns out to be able to see the future by offering each of some four-year-olds a piece of

candy and watching how he or she deals with it. Some children reach eagerly for the treat they see.

Some last a few minutes before they give in. But others are determined to wait until the last moment.

By the time the children reach high school, something remarkable has happened. A survey found that

those who as four-year-olds had enough self-control to hold out generally grew up to be more popular,

adventurous, confident and dependable. The children who gave in to temptation(诱惑) early on were

more likely to be lonely, easily frustrated(沮丧)and inflexible(固守己见的).

Actually, the ability to delay reward is a sign of emotional intelligence which doesn't show up on an IQ

test.

     The hardware of the brain and the software of the mind have long been scientists' concerns. But

brain theory can't explain what we wonder about most, like the question why some people remain

upbeat in the face of troubles that would sink a less resistant soul.

Here comes the theory of Daniel Goleman, writer of Emotional Intelligence: when it comes to predicting

people's success, brain ability as measured by IQ may actually matter less than the qualities of mind once

thought of as "character".

     EQ is not the opposite of IQ. What researchers have been trying to understand is how they work

together; how one's ability to handle stress, for instance, affects the ability to concentrate and put

intelligence to use. Among the ingredients(要素) for success, researchers now generally agree that IQ

counts for about 20%; the rest depends on everything from social class to luck.

While many researchers in this relatively new field are glad to see emotional issues finally taken seriously,

some few fear EQ invites misuse.
