Cattell's theory & The Big 5 Flashcards
What did Cattell’s theory on personality and traits suggest?
PERSONALITY: characteristics of an individual that allow predictions of behaviour
TRAITS: relatively stable and long-lasting building blocks of personality – predictive value
What did Cattell say are important factors in trait development?
- BOTH ENVIRONMENT AND GENETICS ARE IMPORTANT IN THE DEVELOPMENT OF PERSONALITY:
CONSTITUTIONAL TRAITS: genetically based
ENVIRONMENTAL-MOLD TRAITS: environmentally determined.
What were Cattell’s different types of traits?
-ABILITY TRAITS
- TEMPERAMENT TRAITS
- DYNAMIC TRAITS
(ALSO SURFACE TRAUTS AND SOURCE TRAITS)
What are ability traits?
- relates to how well we deal with specific situations and how well we reach our goals e.g. intelligence
What are temperament traits?
- relates to styles we adopt when pursuing our goals; highly heritable e.g. intelligence
What are dynamic traits?
- relates to elements guided by motivation e.g. altruistic, competitive
INCLUDES: attitudes (express our particular interests), sentiments (aggregates of attitudes e.g. values), ergs (innate drives)
What is the dynamic lattice?
- the organised complexity and interrelation of dynamic traits.
What are the 6 stages of personality development?
- 0- 6: influenced by parents and siblings
- 6-14: slow independence
- 14-23: emotional disorders and delinquency
- 23-50: generally productive, career, marriage etc
- 50 - 65: development in response to physical, social and psychological changes
- 65 to death: adjustment to different kinds of losses e.g. death of a spouse.
What are surface traits?
- individual’s overt behaviorus e.g. worry
- cluster together and have high correlations
- first order traits
What are source traits?
- major dimensons
- consist of constellations (clusters) of surface traits
What is Cattell’s Specification Equation to predict indvidual behaviour in a given situation?
P = S1T1 + S2T2…
What is the lexical approach to personality? (i.e. the lexical hypothesis - proposed by Galton)
- if individual differences are important, they should be encoded in language through TRAIT DESCRIPTORS
What are the assumptions of the lexical hypothesis?
- Frequency of word use –> importance of trait
- NO. of synonyms–> importance of difference
- Cros-cultural presence–> universality of traits/importance
What were the core ideas of Cattell’s theory of trait development?
ALLPORT’S 4508 TRAITS –> reduced to 171 through synonym elimination –> narrowed to 36 through experts’ ratings –> surface traits
What were Cattell’s sources of data?
L-DATA: (life record data)- behavioural records collected primarily from peer-ratings e.g. school records
Q-DATA:(questionnaire data)- psychometric self- report assessment
T-DATA: (test data)- objective tests e.g. psychological tests
