Rest of Semester Flashcards
Describe factor analysis
A correlational technique for reducing the possible number of traits to a manageable number
what is the purpose of factor analysis?
To interpret emerging patterns found in managed data
What two types of traits did Cattell propose?
Surface traits and source traits
Describe surface traits
refers to observable things e.g. trait of friendliness can be seen by smiling, saying hello etc.
Describe source traits
more explanatory - underlying causes of surface traits
What was Cattell’s goal?
To identify source traits through factor analysis through 3 sources
Cattell’s 3 sources - L Q T
L- life records
Q - questionnaire
T - tests
How many personality factors or ‘source traits’ did Cattell devise?
16 - now developed into the 16PF personality test
What were Eysenck’s 3 personality dimensions?
Extraversion-Introversion (E)
Neuroticism - Stability (N)
Psychoticism (P)
true or false: most traits have a normal distribution
True - Eysenck’s dimensions are in fact on a continuous scale
What are the four stages of organisation into specific actions (Eysenck)
Type - introversion
Traits - persistence
Habits - persists with hobbies
Specific behaviours
Who is high psychoticism found in?
high degree of psychopathy found among schizophrenics, criminals, sociopaths etc.
What are some dispositions of people with high P (psychoticism) scores?
- troublesome, not fitting in
- cruel, inhumane
- hostile and aggressive
What supporting evidence is there for introverts have higher levels of cortical arousal than extraverts?
- conditioning speed
- drugs (depressants and stimulants)
- relation between performance and stress
Summarise the Yerkes-Dodson Law
inverted U-shape, as arousal goes up our performance increases to the ‘optimal level’, extra arousal after this level will result in drop in performance
What is the emerging consensus for number of factors needed to describe personality?
5 factors
What are the 5 factors? Who devised the model?
Costa & McCrae's five factor model: Openness Conscientiousness Extraversion Agreeableness Neuroticism
What is personality assessment?
Gathering of info about a person to aid understanding, prediction or decision making about said person
Briefly summarise two basic assumptions underlying personality assessment
- there is consistency over time within an individual
- sufficient regularity and similarity in overt behaviours
What are the three requirements for a good personality test?
- Reliability
- Validity
- Standardisation
What is meant by reliability?
the extent to which a test produces consistent results
What is meant by validity?
extent to which a test measure what it claims to measure
According to Mischel (1968), what is the correlation of cross-situational consistency?
r = 0.3, that is, the same behaviour from an individual across different situations has a correlation of 0.3
What are two levels of influence?
- Sociocultural
- Situational
Note: refers to physical and social environment e.g. the whole psychological situation
