Personality Psychology

Chapter 9

Traits and Trait Taxonomies

slide2

Dispositional Perspective

  • People display continuity or consistency across their own actions, thoughts, and feelings
  • People differ from one another in many profound ways
  • Major theory under this perspective
    • Type and Trait Theory
slide3

Classification

  • Characteristic of most sciences in their attempt to find order
  • One of most basic approaches to understanding personality
  • Common sense approach
  • To discover order about personality
slide4

Type and Trait Theory Defined

  • A dispositional theory that explains personality as a set of stable characteristics within individuals
  • People exhibit these characteristics across various situations and across time
slide5

Specific Definitions

  • Types
    • Original definition: Discontinuous categories
    • Current definition: Large, continuous categories encompassing traits
  • Traits
    • Continuous categories
slide6

Key Components

  • Types and traits both exist in a hierarchical order
  • Types and traits are governed by a variety of potential processes
  • Factor analysis often used to determine hierarchies
  • Traits can be distilled into a few general categories; “Big 5” Model one of most popular
slide7

Key People

  • Allport
  • Cattell
  • Eysenck
slide8

Trait theory…

… is a way to describe/predict but it is NOT a theory of development

slide9

How do you discover traits?

Step 1: Choose your method

Lexical Approach: Collecting words and synonyms of traits

Statistical (Empirical) Approach: Use factor analysis

Theoretical Approach: Borrowing theories, especially from ancient scholars, and determining traits from these theories

slide10

Step 2: Distill using

Factor Analysis

  • Statistical procedure to identify items that group together and reflect a larger factor
  • Problems
    • Selection of traits
    • Labeling of factors
    • Number of factors
slide11

Gordon Allport

  • “Father” of trait theory
  • Founded upon personal experience
  • Took a lexical approach to developing trait theory
slide12

Allport’s view of trait theory

  • There is value in surface characteristics – there is more to a person than what is at the “unconscious” level
  • It is not necessary always to emphasize one’s past
  • To discover what someone is like – Ask them about themselves! They are the best source of information
  • Traits are both inherited and learned
slide13

Allport’s view of trait theory

  • Common Traits
    • Traits that are defined the same way for all people
  • Personal Traits
    • Unique manifestation of traits
slide14

Types of Personal Traits

  • Cardinal disposition
    • One single trait that defines everything everything for a person
  • Central disposition
    • 5 –10 highly characteristic and frequently seen personal traits
  • Secondary disposition
    • Influential traits that are less consistent and generalized than cardinal or central traits
slide15

Raymond Cattell

  • Empirical approach to trait theory
  • Factor analysis reduction of 4,500 trait words (left by Allport) to 16 most basic primary personality dimensions
  • Not as concerned with whether traits were inherited or learned
slide16

Cattell’s 16 personality dimensions

  • Reserved vs. Warm
  • Concrete Abstract
  • Reactive Emotionally stable
  • Deferential Dominant
  • Serious Lively
  • Expedient Rule-conscientious
  • Shy Bold
  • Utilitarian Sensitive
  • Trusting Vigilant
  • Practical Imaginative
  • Forthright Private
  • Self-assured Apprehensive
  • Traditional Open to change
  • Group-oriented Self-reliant
  • Tolerates disorder Perfectionistic
  • Relaxed Tense
slide17

Source versus Surface traits

  • Source trait
    • Causal factor trait that determines how a person responds
  • Surface trait
    • Manifestation of a source trait
slide18

Three types of traits

  • Ability traits
  • Temperament traits
  • Dynamic traits
slide19

Ability traits

  • Define various types of intelligence and determine how effectively a person works toward a desired goal
    • Fluid intelligence (innate ability to learn)
    • Crystallized intelligence (the effects of education; what has been learned)
slide20

Temperament traits

  • Inherited source traits that determine the general style of interaction
slide21

Dynamic traits

  • Motivational traits
    • Ergs (innate motivation traits)
    • Meta-ergs (learned, environmental origin)
slide22

Hans Eysenck

  • Theoretical approach to trait theory
  • Took theories of Hippocrates, Jung, et. al., and conceived of a basic 2x2 matrix of super traits
  • Believed traits were genetically-based” was very biologically oriented
slide23

Two dimensions (“Supertraits”)

  • Introversion/extraversion: Tendencies toward sociability, craving for excitement, liveliness, dominance, activeness
  • Emotionality/stability: Ease and frequency with which a person becomes upset and distressed, with greater moodiness, anxiety, and depression reflecting greater emotional instability
slide24

Eysenck’s Two Dimensions

Emotionally Stable Emotionally Unstable

|

Introvert |Phlegmatic (calm): Melancholic (depressed)

| passive, careful, controlled quiet, submissive, anxious,

| reserved

Extravert | Sanguine (optimistic) Choleric (irritable)

| sociable, outgoing, active, impulsive,

| lively, carefree excitable, aggressive

slide25

Trait issues

  • How many categories?
  • Does the approach used to develop trait theory (empirical, theoretical, lexical) make a difference in outcome?
  • Did all trait theorists follow the same assumptions presented for dispositional theory? What is the paradigm?
slide26

Where did trait theory go after

Cattell and Eysenck?

  • Following Cattell, trait data collected in new, more comprehensive, and multivariate ways
    • Further factor analysis
    • Cattell’s data replicated with new, diverse samples, multiple cultures, different languages, children, and over time
    • “lay-person” trait terms included
    • More observations and nonverbal assessments
  • Findings showed 5 factors!
slide27

The “Big 5”

  • Extraversion (Power)
  • Aggreeableness (Love)
  • Conscientiousness (Work)
  • Emotionality (Affect)
  • Openness to Experience (Intellect)
slide28

The Fifth Factor?

  • Given different names by different researchers
  • Cross-cultural differences
slide29

Reactions to “Big 5”

  • Support
    • Eysenck and his camp
    • More robust and replicable than any other taxonomy
    • Is a well-established basis on which to build
    • Research for additional factors is not compelling and the factors are not relevant to personality (attractiveness)
    • Is a framework for phenotypic attributes of personality based in human language
  • Opposition
    • There may be more factors (sexiness, attractiveness, faithfulness, spirituality)
    • Does not capture underlying personality processes
