Personality’s Practical Importance
- how traits predict important life outcomes, e.g. who is most likely to have a stable, long
and successful life
Correlation Coefficient
- -1 ≤ r ≤ +1
- it is the degree of association between two variables, sometimes called a validity
coefficient
- small: .10, medium: .30, large: .50
- validity coefficients (.10-.30)
- reliability coefficients (.70-.90)
- Mischel traits have a limited utility in predicting behaviour (low predictive validity) .30
“a personality coefficient”
- effect sizes is psychology are comparable to, and often larger than, those found in
medicine
- narrow traits specific outcomes
- broad traits general outcomes
The Big Five
- neuroticism, extraversion, agreeableness, conscientiousness, openness
Ozer & Benet-Martinez
- Individual Outcomes outcomes that do not inherently involve a social process in order
to define or give meaning to the outcome variable e.g. happiness, mental/physical health,
longevity
- affective component (high pa, low na)
- cognitive component (high life satisfaction)
-
- Interpersonal Outcomes outcomes that inherently involve other specific individuals
e.g. establishment/maintenance of personal relationships with family, friends, and
romantic partners
- Social/Institutional Outcomes outcomes from impersonal social processes/interactions
with generalized others e.g. occupational performance, volunteerism, and criminality
