|
Two basic formulas of personality
|

3 elements of Act Frequency Research Program
|
1.Act Nomination: Organizing traits into categories+cat. naming 2.Prototypicality Judgement:centralizing important traits in cat.
3.Recording of Act Performance: Self-Report, observer report
|
Disadvantages of Act Frequency Approach
|
1. Context of trait, degree of relevance
2. Failures and Covert acts are not recorded
3.
|
advantages of Act Frequency Approach
|
1. links behavioural patterns+traits
2. meaning of traits that are difficult to study
3. helps identify domains
4. predict life events
|
lexical approach
|
all traits listed +defined in dictionary form basis of describing differences among ppl
|
statistical approach
|
factor analysis/other stats. procedures to identify major traits
|
theoretical approach
|
researchers rely on theories to identify traits
|
lexical hypothesis
|
all important individual diff. have become encoded w/in natural language
|
synonym frequency
|
an attribute has not merely 1 or 2 trait adj. to describe it, instead w/ many words
|
Cross-cultural universality
|
a trait will transcend cultures +codified an important trait
|
disadvantage w/ lexical approach
|
1. does not take into account nouns, adverbs, adjectives
|
statistical approach starts w/
|
1. Lexical approach
2. self-ratings reports
3. personality relevant sentences
|
goal of Stat approach
|
identify a map of personality
|
factor analysis
|
identifies groups of items that go together but tend not to group w/ others
|
factor loadings
|
degree to w/h items correlate w/ underlying factor
|
Disadvantage of Factor analysis
|
1. If a trait is over looked, it will not show up in results
|
theory helps....
|
identify the important variables of personality
|
Theory of Sociosexual orientation
|
Men and women will seek 1 of 2 diff. relationships including monogamy or promiscuity
|
Eysenck's Hierarchical Model of Personality
PEN
|
E=Extroversion/ Introversion
N=Neuroticism/ emotional stability
P=Psychoticism
|
biological underpinnings of Eysenck system
|
1. heritability: PEN traits are genetic
2. identifiable physiological substrate: identify properties of brain/ CNS = traits
|
Disadvantages of Eysenck System
|
1. more traits then the ones in PEN
2. many other traits are heritable then PEN
|
Cattell's Taxonomy: 16 Personality Factor System
|
uses S-data+T-data to develop the true factors of personality=16 traits
|
Timothy Leary + Jerry Wiggins
|
circular model of personality with statistical techniques
|
interpersonal traits
Jerry Wiggins
|
what ppl do w/ & to each other ex. temperament, character traits
|
interpersonal traits are also called
|
interactions or dyaddic interactions
|
3 advantages of Wiggins circumplex
|
1. clear explicit definition of interpersonal behaviour
2. specifies relationship b/w each trait & every other trait in model
3. alerts investigators to gaps in investigation
|
adjacency
|
how close traits are to each other in circumplex
|
bipolarity
|
located at opposite side of circle, negatively correlate
|
orthogonality
|
traits are perpendicular to each other on model are entirely unrelated
|
Five- factor Model of Personality
OCEAN
|
1. Openness-intellect
2. consciousness
3. Extraversion
4. Agreeableness
5. Neurotism/stability
|
5-factor model
Allport+Odbert
(1936)
|
combined lexical(Cattell 4,500 traits)+ statistical approach (Fiske - factor analysis)
|
Tupes&Christal
5 - factor M
|
simplified 22 categories of traits to 5 - factors
|
NEO-PI-R
Costa & McCrae
|
Neuroticism-extroversion-openness Personality Inventory Revised
|
fifth factor problem involves
|
finding a correct name for openness & intellect: lexical A. across cultures
|
Social attention is a cardinal feature of
|
Extraversion
|
Critics of 5-Factor M. include traits from
7- factor m + 6-factor m
|
1. positive/negative evaluation
2. religiosity/ spirituality
3. attractiveness
|
traits that fall outside of 5-factor M
|
Conventionality, Seductiveness, Manipulation, thriftiness, humorousness, integrity, femininity, religiosity, risk taking, egotism
