Q

Who was Gordon Allport (1897-1967)?

A

Regarded as founder of trait approach
- identified over 18000 English words used to describe individual differences and then eliminated temporary states and evaluations - 4500 used to describe personality traits - many were synonyms
- Used idiographic research methods - mostly case studies, analysing interviews and personal documents, using phenomenological approach

25
What are source traits?
Identified via factor analysis - refers to underlying trait that is responsible for variance in observable surface traits
26
What are the 2 competing schools within psych?
1. personality theorists whose main focus on development theories with little emphasis on empirical evaluation 2. experimental psychologists who had little interest in individual differences
27
Who was Hans Eysenck?
Proposed integration of the 2 competing schools in psych - identify personality dimensions - devise means of measurement - test using experimental procedures Concluded that there are 3 basic personality dimensions - referred to as types
28
Which 2 dimensions did Eysenck first propose to be associated with a person's normal functioning?
Extroversion-introversion Neuroticism-stability (both have biological underpinnings) - intersection of these scales led to 4 temperaments being proposed
29
What personality dimension did Eysenck add in 1976?
Psychoticism
30
What is Eysenck's extroversion-introversion dimension?
- interactivity with others - extraverts seen as sociable and impulsive who love excitement - introverts seen as quiet, introspective individuals who prefer well-ordered life
31
What is Eysenck's neuroticism-stability dimension?
- Measure of emotional behaviours - Neurotics were seen as emotionally unstable with unreasonable fears and obsessional symptoms
32
What is Eysenck's psychoticism factor?
Added as a continuum based on antisocial hostility - on a spectrum from aggressiveness and egocentricity to higher degree of self-control
33
What are high levels of psychoticism linked to?
Vulnerability to mental conditions (psychosis) but also potentially creativity - believed there was a genetic, heritable aspect of P
34
What are some characteristics of psychoticism?
aggressive, anti-social, cold, non-empathetic, egocentric, creative, impersonal, tough-minded, impulsive
35
What did Eysenck believe extraversion, psychoticism and neuroticism made up?
The basic structure of personality (PEN model) - developed EPQ (Eysenck personality questionnaire) - good psychometric properties for E and N
36
What is the theorised basis for differences in extraversion?
- Lower level of cortical arousal - Highly-extraverted people naturally less stimulated so they seek it out
37
What is the theorised basis for differences in neuroticism?
- More reactive limbic (nervous) system - Highly neurotic individuals are more sensitive to environmental stimuli
38
What is the theorised basis for differences in psychoticism?
- Low levels of dopamine - Vulnerability to inhibit irrelevant stimuli and impaired learning of societal rules
39
What type of evidence did Eysenck use to support his theorised basis for differences in PEN dispositions (biological bases)?
Evidence of consistency, cross-cultural similarity and support of twin studies
40
What is temperament?
General behavioural patterns
41
What are the 3 dimensions of temperament (Eysenck)?
Emotionality Activity Sociability
42
What did the big 5 emerge from?
A lexical hypothesis - assertion that the strongest differences between individuals' personalities will be reflected in language
43
What aspects of personality were identified by Fiske (1949) from a lexical list?
- inquiring intellect - conformity - confident self-expression - social adaptability - emotional control
44

66
How did measurement of the big 5 develop?
Costa and McCrae (1985) - NEO (questionnaire for neuroticism, extraversion and openness) -> NEO-PI-R (revised to include agreeableness and conscientiousness) - consists fo 240 items assessing 30 specific traits (Psychometric properties show good reliability and content validity according to Costa, 1996.) -> NEO-FFI (more concise) - 5 scales w/ 12 items (60 total) on 5 point likert scale and translated to several languages Latest version: NEO-FFI-R
67
What has cross-cultural replication shown about the big 5?
They replicate well across most cultures but there has been some evidence that failed to fully replicate this structure in Chinese populations. - Support cross-culturally and replicate across research into a wide range of applications eg. job performance - behavioural relationships/outcomes similar across cultures
68
What are some big 5 correlates?
Success at school/work Happiness Love and relationships Stress and coping with stress Overall life quality (especially related to high C and A)
69
What have twin studies shwon about the big 5?
Big 5 personality traits have substantial heritable components explaining 40-60% of variance. BUT identification of associated genetic variants has remained elusive.
70
What did Power and Pluess (2015) find about heritability of big 5?
Found significant and substantial heritability estimates for neuroticism (15%, SE=0.08, p=0.04) and openness (21%, SE=0.08, p <0.01) BUT not for extraversion, agreeableness and conscientiousness
71
What did Vukasovic and Bratko (2015) find in their large scale meta analysis about influences on individual differences in personality?
40% attributed to genetic influenes 60% attributed to environmental influences
72
What are the 3 approaches to identifying traits?
1. analysis of natural language (lexical approach) 2. Using statistical techniques (eg. factor analysis) to identify patterns in data 3. Theorising -> deducing fundamental traits In practice, these are blended or one is used to validate another - strong emphasis on measurement and quantitative techniques but little emphasis on outcomes because it is believed that traits are not easily changed.
73
What did Denissen et al., (2019) find about personality change over life events?
Life events had surprisingly small effects on personality changes - obtaining employment increased emotional stability - emotional stability increased in period before childbirth and then dropped again
74
What are 4 critiques of trait approaches?
- Misconceptions of interactions between brain physiology and mind states - Mischel (1968) claimed that many of the measures are largely descriptive - Trait approaches do not explain behavioural differences across situations - Labelling factors and measurement issues
75
What are 5 strengths of trait approaches?
- empirical investigation - questionnaires developed - not bound to theoretical assumption - Scientifically sound area of psychological research - cross-cultural consistency in 5 factors
76
What are 5 limitations of trait approaches?
- heavy reliance on self-reports - derived from everyday language - factor analysis is only as good as the items included - descriptive but not explanatory - factors may not mean the same thing across cultures
