PREFACE<br />

Preface<br />

Not long ago, psychologists interested in the differences<br />

between individuals thought they had<br />

a good handle on how to describe individual<br />

differences systematically. Differences in aptitude<br />

for performing mental and physical tasks belonged to the<br />

domain of abilities. The most famous of these is general intelligence<br />

(g or IQ), along with a host of other, more narrowly<br />

defined abilities. Differences in people’s typical experiences of<br />

the world, along with characteristic behavioral styles, were part<br />

of personality. Multiple personality traits, such as extraversion<br />

and neuroticism, were discriminated. Individual differences<br />

in motivation, such as needs for achievement or affiliation with<br />

others, were sometimes seen as a third domain. This overall<br />

scheme for describing individual differences had its roots in the<br />

late 19th century, and, over more than a century, spawned a<br />

huge enterprise of psychometric test development, along with<br />

numerous lines of research on just what it is that is measured<br />

by these tests.<br />

Developments in research and popular culture upset this<br />

settled view in the 1990s when the new concept of emotional<br />

intelligence (EI) came along. Broadly, EI refers to abilities for<br />

understanding and managing emotions, which may be especially<br />

important for relating constructively to others. EI may be<br />

different from conventional intelligence in that, in the realm of<br />

the emotions, success depends not so much on rational analysis<br />
