Q

What is the lexical hypothesis

A

The words people use in the English language, reveal what people find important when describing personality

Galton (1822-1911)

(when looking to describe personality, turn to dictionaries)

Q

What are the two assumptions of the lexical hypothesis

A
  • Most meaningful traits will be used in language as single terms
  • Number of words in a language (that refer to the trait) correspond to its importance (in describing personality)

Q

What is a criticism of the lexical hypothesis (Norman, 1963)

A
  • If lexical hypothesis is valid
  • then it should apply across diff cultures & languages

But it doesn’t (evidence of this later)

Q

What is a nomothetic approach strategy

A

Focus on similarities btwn groups of indivs
-Indivs are unique only in way their traits combine

Q

What is the goal of the nomothetic approach

& Indentify the minimum number of traits required to describe personality universally

Q

What is the methodology of the nomothetic approach

A

Quantitative methods to:
- Explore structures of personality
- Produces measures of personality
- Explores rship btwn variables across groups

Q

Q

What is Cattell’s Factor Analysis (16 PF)

A

Way of reducing data from many variables to their underlying dimensions

find correlated traits & list as one cluster/factor (common denominator)

Q

What was Cattell’s theory of personality

16 PF

A
  • Personality is the characteristics of the indiv that allow prediction of how they’ll behave in a given situation
  • Traits are stable, long-lasting building blocks of personality

15
Q

Where did the 16 factors come from

Cattell 16 PF

A
  • Factor analysis revealed 16 personality factors
  • Cattell’s 16PF came from the factor analysis of the list of 4,500 trait names identified by Allport and Odbert (1936)

Q

Weakness of Cattell 16 PF

A

Problems with replication attempts (Conn and Rieke, 1994)

17
Q

What is Eysenck’s 3 factor approach

A
  • Observe responses in specific situations
  • Typical responses = habitual response
  • Particular traits emerge
Eysenck (1947; 1952)
18
Q

What is a supertrait

Eysenck 3 factor approach

A

Grouping of traits

next logical step of the model

19
Q

What are the 3 supertraits of Eysenck’s 3 factor personality model

A

Sociability

Neuroticism

Psychoticism

20
Q

How was personality measured in Eysenck’s 3 factor model

A

Eysenck Personality Questionnaire (1975)

21
Q

Weakness of 3 factor model

Eysenck

A

Too reductionist

3 traits is far too few

22
Q

What is Costa & McCrae’s (1992) Personality Theory

A

5 factor approach
OCEAN

  • Built on lexical hypothesis foundation
  • Statements that pps agree/disagree with can better access components of personality
  • Analysed the data
  • NOT based on a theory of 5 factors, which is then tested, but rather a data-driven hypothesis
23
Q

What is the HEXACO model

A

Ashton & Lee (2007)

  • Honesty-humility
  • Emotionality
  • Extraversion
  • Agreeableness
  • Conscentiousness
  • Openness

Developed after conducting international research using the 5 factor model, discovering a 6th

24
Q

How can the 6 traits in the HEXACO model be organised

Ashton & Lee (2007)

A
  • Honesty/Humility, Agreeableness, Emotionality
    -contribute to altruism
  • Extraversion, Conscientiousness, Openness To Experience
    -relate to biological separate areas of behaviour
25
Which factor is best? 3, 5, or 6
* Eysenck’s 3 seem to have lost the debate. Irrelevant * HEXACO might be a useful revision to the Five factor model * Difficulties in determining the “truth” may reflect the use of factor analysis. Could be argued it's just "agreeableness" for the sake of discovering something new * Multiple methods may be needed | lowkey depends on your own opinion
26
How are personality traits measured
* Self-report * Other report (e.g., observer report) * Behaviour observation * Physiology -hormones -brain activity -genetics
27
What the bombaclaat is the big one
Musek (2007) 2 Main Factors Stability (conformity) Plasticity (non-conformity) 2 factors are further reduced to 1 big ass factor The general factor measures the factors that are cross culturally highly valued
28
Advantages of self-reports as a means of measuring personality
* Quick & easy; cheap * You yourself (arguably) have the best insight
29
Disadvantages of self-reports as a means of measuring personality
* Biases in responding: social desirability & dishonesty * Not measuring the biological basis e.g., neuroticism at the level of self-report may be masked by learned strategies
30
Advantages of observer reports as a means of measuring personality
* Quick & easy; cheap * Close peer has good insight into mind of their friend * Can provide convergent perspective
31
Disadvantages of observer report as a means of measuring personality
* Some traits MUCH harder to judge externally -e.g. smiling/laughing marker of extraversion whereas neuroticism harder to access * Peer has no access to inner thoughts -despite perception that they do * (Although not that important for Big Five but rather for other more intimate aspects of personality e.g. sexuality)
32
Weaknesses of personality trait approaches as a whole | Mischel 1968 & 2009
* Discrepancy btwn what he observed & assumptions of trait theory (some have 3, 5, 6 factors, disagreements etc) * Trait models largely descriptive & not predict behaviour * Lack of cross-situational consistency of behaviour -Can't be predicted using trait theory (characterised as the person-situation debate)
