avoiding others that seem to cause
pain—lie at the heart of all human
activity. As a group, extroverts tend to
be reward-seeking, but every human
being has her own mix of approach and
avoidance tendencies, and sometimes
the combination differs depending on
the situation. Indeed, many contemporary
personality psychologists would say
that threat-vigilance is more characteristic
of a trait known as “neuroticism”
than of introversion. The body’s reward
and threat systems also seem to work
independently of each other, so that the
same person can be generally sensitive,
or insensitive, to both reward and
threat.
