field of study
devoted to discovering the genetic bases for
personality characteristics
BEHAVIORAL GENETICS –
by comparing
identical twins to fraternal twins,
especially when twins can be found who
were not raised in the same environment,
researchers can begin to find evidence of possible genetic influences on various
traits, including personality
TWIN STUDIES
The __revealed that
identical twins are more similar than
fraternal twins or unrelated people.
Minnesota twin studies
While the__ has a significant
impact, even if shared, genetics account
for most of the similarity among siblings.
environment
the genetics of
a child’s parents, even those not
inherited, can impact the family
and child’s environment.
Genetic Nurture –
– studying
unrelated people who are raised in the
same environment should help
investigators discover the influence of the
environment.
ADOPTION STUDIES
Adoption studies have shown as well that
__account for a great deal
of personality development, regardless of
shared or non-shared environments.
genetic influences
– Dr. Franz Joseph
Gall’s theory of personality traits, based on
the shape of a person’s skull.
PHRENOLOGY
States that certain areas of the brain were
responsible for certain aspects of
personality and that the skull itself would bulge out according to which of these
traits were dominant
PHRENOLOGY
rests on the idea that aspects of our
personality must be related to consistent
patterns of functioning in the brain.
– Uses both structural and functional
neuroimaging methods to explore the
biological bases of personality.
PERSONALITY NEUROSCIENCE –
looks at personality through traits
that are related to variations in
brain structure and also through
characteristic adaptations, or how
someone’s life circumstances
influence their individual goals, strategies, and personal
interpretations.
Cybernetic Big Five Theory –
– how much some
trait within a population can be
attributed to genetic influences.
Heritability
– a way of choosing
the parts of different theories that
seem to best fit a particular
situation.
Eclectic view
the
preferred method for behaviorists is to
watch behaviors unfold in the real world.
BEHAVIORAL ASSESSMENTS –
assessment
in which the professional observes the client engaged in ordinary,
day-to-day behavior in either a
clinical or natural setting.
Direct Observation –
