Personality change
-internal: not situational changes. Not dependant on environment.
Key forms of stability
-rank order: someone’s behaviour stays relative to the group. Ex: most impatient person in 2005 is still
most impatient now.
-coherance: personality traits are displayed in different ways as we grow up.
-sometimes behaviour seems odd and not consistent but it can be to a common end motivation or goal
-state: what is occurring in the moment
-trait: more long term behaviour
-ex: personality trait of assertiveness. Look at how someone is being assertive in a certain state.
-enactment: did the act occur? Did the act occur on average? If provided the opportunity, did the act
-absolute: everything must be absolutely identical for it to be considered consistent
-ipsative: being consistent with yourself. Ex: if you are more adventurous than out going. Then those
traits must be displayed that way all the time.
-all these aspects intertwine
Looking at change
-population: does the change occur to the large majority
-group difference: specific groups might be more prone to personality change
Individual difference: at risk behaviours
Personality stability
-temperament: different reactions to same stimulus or event. Different characteristics you can see in
young children. Won’t necessarily act this way when they grow up.
-a child who’s more active now will be more active later on
-more accurate consistency over shorter time span
-longitudinal is the best way to look at change over time. Tracking the same people over long span of
-Farther the difference is in number of years the less the correlation is
-aggressive behaviour at early stage in life is associated with criminal convictions
-the older you are when a rank order is first taken, the more stable it will be. (ex: if rank order is taken at
40 and taken again it 60 it will be better than if taken at 25 and again at 60.
-in general everyone changes during adulthood.
-neuroticism: worriers, anxiousness, stress. Perspectives change over time
-conscientiousness: aware of your surroundings.
-meta analysis: a study that looks at all research that has been done in a certain field.
