Hans Eysenck’s(1916-1997) research
strategy…
…begins by dividing the elements of personality
into various units that can be arranged
hierarchically.
The basic structure…
…in this scheme is the specific response level,
which consists of specific behaviors. For
example, if we watch a man spend the
afternoon laughing and talking with friends,
we would be observing a specific response.
• If this man spends many afternoons each
week having a good time with friends, we
have evidence for the second level of
Eysenck’s model: a habitual response.
• If you watch long enough, you may find that
he lives for social gatherings, discussion
groups, parties and so on.
• In Eysenck’s terms, this person exhibits the
trait or character of sociability. Traits such as
sociability are part of a still larger dimension
of personality.
• Sociable people also tend to be impulsive,
active, lively and excitable. All these traits
combine to form the supertrait Eysenck calls
extroversion.
How many of these supertraits are
there?
• Eysenck’s research yielded evidence for two
basic dimensions:
• extraversion-introversion and neuroticism.
If you are a prototypic extravert,
• You are outgoing, impulsive and uninhibited; you
have many social contacts and you frequently
take part in group activities.
• The typical extravert is sociable, needs to have
people to talk to, does not like reading or
studying by him/herself.
An introvert is…
…a quiet, retiring sort of person, introspective,
fond of books rather than people; s/he is
reserved and distant except to intimate
friends.
• Of course most people fall somewhere
between these two extremes but each of us is
perhaps a little more of one than the other.
• Eysenck argues that introverts and extraverts
differ not only in terms of behavior but also in
their physiological makeup. They have
different levels of cerebral cortex arousal.
• Extraverts generally have a lower level of
cortical arousal than do introverts. They seek
out highly arousing social behavior because
their cortical arousal is well below their
desired level when doing nothing.
• In a sense, they simply try to avoid unpleasant
boredom.
• Their problem is feeding their need for
stimulation.
• Introverts typically operate at an aboveoptimal cortical arousal. They select solitude
and nonstimulating environments in an effort
to keep their already high arousal level from
becoming too aversive.
• There is ample evidence that introverts are
more sensitive to stimulation rather than
extraverts are.
• That is, for example, introverts are more
quickly aroused when exposed to loud music.
They are more responsive to chemical
stimulants such as caffeine or nicotine.
• Extraverts are quickly bored by slow-moving
movie plots and soft music because they are
less likely to become aroused by these subtle
sources of stimulation than introverts are.
