Week 2: Personality Psyc Flashcards
the 3 levels of Personality
lvls:
1) dispositional traits
2) characteristic Adaptations
3) life narratives
they are hierarchical (3 is the highest)
1) Dispositional traits
- broad descriptions of patterns of behavior and experience
-relatively decontextualised
as it arises from v. broad classes of stimuli and situations
Dispositional traits:
Allport and Odbert (1936)
they have a Lexical Hypothesis:
impt chars coded in language.
18k descriptors
Prob: v. unwieldy, a list rather than a system
Cattell (1943):
reduced Odbert’s list to Cattell’s 16 Personality Factors (traits)
Precedure
1) 18,000 descriptors
2) Sorted into 160 clusters of synonyms/antonyms
3) Discarding near-identical descriptors
4) Final list of 171 descriptors
5) 100 participants rate 1-2 friends on the 171 descriptors
6) Factor Analysis
7) 16 Personality Factors
Dispositional Traits:
content
strengths
limitations
content) Broad, coherent patterns of behaviour and experience
strength) Universal structure, high predictive value
limitation) Lowest resolution description of a person
Problems with Cattell’s 16 Personality Factors
1) Subjectivity
2) Poor Replicability / Reproducibility
3) Redundancy
Problems with Cattell’s 16 Personality Factors
1) Subjectivity &
2) Poor Replicability / Reproducibility
Different people reach a different reduced set of Allport
& Odbert’s descriptors
cannot obtain the same set
Problems with Cattell’s 16 Personality Factors
3) Redundancy
Many of his factors correlated too highly for them to really be ‘different’ traits
Digman, 1990 created:
The Big Five
1) Extraversion
2) agreeableness
3) conscientiousness
4) Neuroticism
5) openness
Hierarchical Structure of Traits
1) Nuances (very narrow: liking something)
2) Facets (energy lvl. + emotions)
3) Aspects (enthusiasm)
4) Domains (big 5)
5) Meta-traits (stability, plasticity: v. broad)

Measurements of B5:
Questionnaires:
3 methods used to Estimate Reliability
Temporal stability
1) Test-retest reliability
(Correlation between T1 score and T2 score)
Internal consistency 2) Split-half reliability (Correlation between scores: half & half) 3) Cronbach's Alpha (Average of all possible split halves)
