PSYC 2740—Personality disposition over time: stability,
change and coherence (chapter 5)
Key part of personality development
Stability over time:
o Rank order
o Mean level stability
o Personality coherence
How does something qualify as Change over time:
o Internal—in order for personality to change, has to be internal. When
under the influence, or sick, short-lived and would therefore not be
o Enduring—has to be permanent, like a brain injury causing
personality changes for example.
Analyzing stability and change
Individual differences—do certain personality traits lead to certain life
outcomes (job selection, relationship etc.)
o Examples of stability across the lifespan:
Know that stability does exist throughout lifetime
Temperament—early differences involved in behaviors (e.g.
See really stable and early individual differences between
There is more stability over shorted intervals
o From 3-6 rather than 3-12, and as get older, more
stability in temperament.
Block and block longitudinal study—assessed activity
level via actometer and teacher ratings
o Found that at different ages: Results from both measures were positively
correlated (validity was present)
Results from same measure but at different
times were correlated (suggested that over
time, was stability therefore reliability and
thus test re-test reliability)
Activity was relatively stable with more
stability over shorted intervals
E.x. aggression in males—more
stability in smaller vs. larger times
spans and therefore have correlations
that are more statistically significant.
Bullying and problems later in life
Different raters identified same youth as bullies
At 24 years, 65% of the bullies had felony convictions—
says that being bully as child/some personality traits that
are associated with that may be related to the way act
when older which shoes there is some stability present
for at least some of kids.
The Big 5
Relative stability in adulthood; especially > 50 yrs.
BUT, openness, extraversion, neuroticism decline
slightly until 50. When saying changes, are very slight
and levels decline but traits are still present.
Self-esteem is something that “changes.”
Males increase slightly in self-esteem, females tend to
decrease (important to keep in mind that is general trend
and not something that applies to everyone).
What constitutes for this?
o How we’re socialized
o How the media determines what qualifies as “good
o Objective awareness—thinking everyone paying
attention to you…could be disconnect between how view yourself and how you want to be viewed
can have major impact on positive development of
