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
What do situationists suggest?
That personality doesn’t exist, and that situational factors determine a person’s behaviour
What is interactionism?
The idea that traits and situations combine to produce behaviour e.g. a person will behave according to a trait in some situations, but not others
How can interactionism be tested?
- Experimental method (manipulating situations to observe behaviours)
- Variance-components method (response to naturally occurring situations for analysis - correlation)
What are the models of interactionism?
- Static (person + situation = behaviour)
2. Dynamic (reciprocal relationships between persons, situations and behaviour)
The fundamental problem for the study of personality is…
empirical evidence for human knowledge development
Social psychology can be defined as…
The scientific investigation of how the thoughts, feelings and behaviour of individuals are influenced by one’s social environment
What does social psychology assume?
We construct our world and selves socially, in interaction with other people
What is a meta-theory?
A theory about theories; a more abstract theoretical perspective that finds expression in different concrete theories
Explain the “power of the situation” and how it can affect normal people
Well-adjusted people can commit evil deeds under strong situational demands e.g. Milgram obedience studies
Define situationism
Human behaviour is primarily determined by the forces of the situation, the social environment
The Carnahan & McFarland (2007) differing ad study found that:
volunteers for prison life study were higher in aggression, narcissism and social dominance, lower in altruism and empathy
Explain interactionism
Personality factors and situational factors interact and jointly determine how people act in certain circumstances
When do people take on a group role?
After they have internalised them as part of a social identity shared with other people
What is distinctive about social psych research methods?
manipulation and control, and randomisation. this leads to inferences of causality and high validity levels
What does prior knowledge have to do with social cognition?
Our behaviour depends on the stimuli in a situation, but also prior knowledge that we bring to the situation
What is bottom up processing?
Stimuli received through our senses that are processed
What it top down processing?
Information that we bring to a situation e.g. people wearing suits
Our capacity to process information is limited (social cognition basic assumptions). expand
Depending on capacity and necessity, we process info in a given situation to a greater or lesser depth
What is the basic assumption in social cognition about cognitive processes?
Cognitive processes can be conscious and controlled or automatic and uncontrolled
Define a schema
Cognitive structures containing information about how the social world operates
Explain a prototype in terms of category representation
A prototype is a cognitive representation of the typically ideal characteristics of a category - a stereotype is the same but for groups
How do categories become activated in social cognition?
Depends on how cognitively accessible the categories are - determined by frequency and recency
What is priming?
Exposing someone to a certain aspect of a category so they can expect that from said category
How is motivation relevant to categorisation?
Your motivations at the time depend how you categorise something e.g. a tomato can either be food when hungry or a projectile when angry
