Narrow Personality Traits Flashcards
Hierarchy of Personality Description
(Musek, 2007) General Personality Factor -> (Digman, 1997) Alpha Factor ‘Stability’ (Agreeableness, conscientiousness, neuroticism) + Beta Factor ‘Plasticity’ (Extraversion, Openness)
What is the Bandwidth-Fidelity Dilemma (Cronbach & Gleser, 1965)
- Trade-off between breadth & accuracy
- Broader, higher-level descriptors: predict more, lower accuracy
- Narrower, lower-level descriptors: predict fewer, more accuracy
What did Paunonen & Ashton (2001) find? (Big 5 and grades)
Higher correlation of conscientiousness and final grade than openness to experience
Authoritarianism & Adorno et al (1950)
Attempted to explain recent examples of prejudice and extreme views towards others
Characteristics of Authoritarianism
Preference for unambiguous, familiar routines
Strong views on crime and punishment
Respect for institutions
Uncritical acceptance of authority in society
Reluctance to introspect
Belief that pleasure is wrong
What did Bouchard et al. (2003) find for authoritarianism
Evidence for heritability of authoritarianism from twins reared apart
What did Amodio et al. (2007) find for authoritarianism
Authoritarianism associated with decreased neural response to suppressing a habitual response in Go/No-Go task (and lower response accuracy)
What is the continuity hypothesis
There is no discontinuity between ‘normality’ and illness (Cooper, 2002)
What is schizotypy?
- Correlated items based on clinical descriptions of schizophrenia
- Reflects genetic vulnerability to psychosis
Common symptoms of schizophrenia
Delusions, hallucinations, disorganised speech and behaviour, blunted affect, avolition and poverty of speech
Two concepts/measures of schizotypy
- Oxford-Liverpool Inventory of Feelings (O-LIFE; Mason, Claridge & Jackson, 1995)
- Schizotypal Personality Questionnaire (SPQ; Raine, 1991)
What is the O-LIFE based on?
Factor analysis of:
- Unusual experiences (hallucinations, distortions etc)
- Cognitive disorganisation (anxiety, sense of purposelessness)
- Introvertive anhedonia (lack of enjoyment from social sources, dislike of intimacy)
- Impulsive nonconformity (impulsive & disinhibited behaviour)
What is the SPQ (Schizotypal Personality Questionnaire)
Items developed to capture the 9 features of schizotypal personality disorder: Ideas of reference, excessive social anxiety, odd beliefs, unusual perceptual experiences, odd behaviour, no close friends, odd speech, constricted affect, suspiciousness
Evidence for conceptual validity of schizotypy
- Cognitive inhibition seen less in schizophrenia also seen less in ppl w high schizotypy (Stroop test)
What did Steel, Hemsley & Jones (1996) find (Stroop Test)?
- Calculate size of negative priming, the bigger the difference, the greater the amount of cognitive inhibition
- People w schizophrenia show smaller negative priming effect
- So would expect ppl who have high trait schizotypy to have smaller effect and they did!
