Personality Structure: Classifying Traits Flashcards
Fundamental Lexical Hypothesis: personality traits
“The most important individual differences in human transactions will come to be encoded as single terms in all of the world’s languages.”
(Goldberg, 1990)
Lexical Approach: Early Attempts (I)
Baumgarten (1933), in German
Allport & Odbert (1936), in English 18,000 English words Traits: approx. 4,500 States: approx. 4,500 Evaluations (good/bad): approx. 5,200 Miscellaneous : approx. 3,600
Factor Analysis (FA): statistical technique
Exploratory FA (EFA)
Confirmatory FA (CFA)
Exploratory FA (EFA)
Data reduction technique: aims to explain a pattern of correlations between large numbers of variables
Generates hypotheses
Example: Self-Report
- Questionnaire
- Correlations
- Factors and Factor Loadings
Confirmatory FA (CFA)
Statistical technique for model testing
Tests hypotheses
Early Attempts (II) - Cattell
First factor analysis of 35 traits
12 traits found + 4 added later =16PF (1949)
Cattell’s 16PF
- Abstractedness
- Apprehension
- Dominance
- Emotional Stability
- Liveliness
- Openness to Change
- Perfectionism
- Privateness
- Reasoning
- Rule-Consciousness
- Self-Reliance
- Sensitivity
- Social Boldness
- Tension
- Vigilance
- Warmth
Converging Evidence: Factor Analyses (early lexical studies III)
Tupes & Christal (1961, 1992): 5 factors
Norman (1963, 1967): 5 factors
Costa & McCrae (1985, 1991): 5 factors
Goldberg (1990, 1992): 5 factors
Different samples, ages and nations: 5 factors
Same 5 Factors with different measures
Trait descriptive adjectives
Statements describing affect, cognitions, and behaviour
Self-ratings vs. observer ratings
Nonverbal measures
Five-Factor Model of Personality /“Big Five”
Pervin et al., 2005
Openness (O) Conscientiousness (C) Extraversion (E) Agreeableness (A) Neuroticism (N)
Neuroticism (N)
Assesses maladjustment vs. emotional stability
Identifies individuals prone to:
- Psychological distress
- Unrealistic ideas
- Excessive cravings or urges
- Maladaptive coping responses
Extraversion (E)
Assesses quantity and intensity of :
- Interpersonal interaction
- Activity level
- Need for stimulation
- Capacity for joy
Openness (O)
imagination/intellect
Proactive seeking and appreciation of experience for its own sake
Toleration for and exploration of the unfamiliar
Agreeableness (A)
Quality of one’s interpersonal orientation along a continuum from compassion to antagonism in:
- thoughts
- feelings
- actions
e.g. kind - unkind
Conscientiousness (C)
Assesses the individual’s degree of:
- organisation
- persistence
- motivation in goal-directed behaviour
e.g. lazy = hardworking
Why are the Big Five so important?
Help us sort out the confusion of different models and measures of personality
Provide a kind of “compass” (mapping system) to understand where in the personality space to place specific traits we want to know more about.
