Week 5 Flashcards
Define Personality?
The underlying, relatively stable, psychological structure and processes that organise human experience and shape a person’s activities and reactions to the environment (Lazarus & Monat, 1979)
What is the Trait Approach?
- Personality is comprised of a collection of characteristics (traits)
- Traits determine behaviour
- Traits can be quantified and measured
- Traits evolve over time
What is Cattell’s Trait Theory (1945)?
- Lexical theory; meaning we can attach words to every critical aspect of human personality
- Examined traits in series of factor analytic studies and concluded that there are 16 basic or source traits underlying 4 surface traits
What is Eysenck’s Trait Theory (1944)?
- Individuals high in neuroticism tend to be tense, anxious and depressed
- Extroverts are more sociable and impulsive than introverts
- This is because introverts have higher levels of cortical arousal than extroverts so they do not need to seek external stimulation
- In 1978 he added a 3rd personality factor termed psychoticism: assesses the predisposition to suffer psychotic breakdown - aggressive, egocentric, antisocial tendencies
What four components were used by Eysenck (1952) to identify personality types?
Extrovert/Introvert and Stable/unstable
What is the five factor model?
Norman (1963) obtained evidence for 5 personality factors:
- Openness
- Conscientiousness
- Extraversion
- Agreeableness
- Neuroticism
Goldberg (1990 and 1993) supported this structure
What is an Iceberg Profile of mood and who came up with this idea?
- Morgan (1980)
- Identified superior performance in sport as medium-high levels of vigour, and medium-low levels of tension, depression, anger, fatigue and confusion.
What is an Everest Profile of mood and who came up with this idea?
- Terry (1995)
- Identified superior performance in sport as having really high levels of vigour and really low levels in tension, depression, anger, fatigue and confusion.
What are advantages of Trait Theory?
- Significant progress in identifying major factors of personality
- Strong evidence that heredity plays a role in producing individual differences in personality
- 80% of individual differences in neuroticism are due to heredity; Eysenck and Prell (1951) found correlation between identical twins was 0.85 whereas only 0.22 for dizygotic twins
- Trait approach adheres to scientific methodology and yields testable hypotheses
What are disadvantages of Trait Theory?
- no explanation for changes in personality over time
- Mischel (1968) argued that the central weakness stems from the assumption of cross-situational consistency (people should behave in a reasonably similar ways in different situations)
- Mischel concluded that the correlation between personality and behaviour rarely exceeds 0.30
