Trait Perspective, Needs + Motives Flashcards
the trait approach - builds on?
how ppl intuitively think and talk about each other.
- translated natural + informal language of personality into formal psychology
who is a pioneer in this area?
Allport
2 elements of the trait approach?
1 - based on empirical research that use correlational designs
2 - focuses exclusively on individual differences (how strong trait is compared to other people)
why are trait measurements ordinal, not rational. what does this mean?
ordinal: value reflect ordering each entity that is measured.
- no 0 point, just comparatively higher/lower
the inconsistency in behaviour - some influences?
- situations
- implicit rules of situation
- age
person-situation debate
which is more important? situation or personality?
who triggered person-situation debate
3 arguements for situation:
Mischel - marshmallow guy.
- said traits are poor predictors of behaviours
- situations are better at accounting for differences in behaviour
- personality assessments + everyday intuitions about personality are fundamentally flawed
predictability of behaviour
- tests usefulness of personality trait if you can use it to predict behaviour.
situationist argument on predictability of behaviour
- predictive capacity of personality is limiter
- correlation between personality + behaviour is about .3
response 1 to situationist argument on predictability of behaviour
- unfair literature review
- looked at studied with shitty results.
- many were flawed
response 2 to situationist argument on predictability of behaviour
- we can do better
- weak findings =/= unimportant. rather do better.
- some people may be more consistent than others. (self-monitor, high = change behaviour, low = personality prevails
- focus on behavioural trends instead of single actions at particular moments
response 3 to situationist argument on predictability of behaviour - compare with absolute standard
.3/.4 isnt small.
- comparison with an absolute standard, .4 means that a prediction of behaviour based on a personality trait score is likely to be accurate 70% of the time
response 3 Part 2 to situationist argument on predictability of behaviour - compare with relative standard
.3/.4 isnt small
- compare with relative standard: ability of situational variables to predict behaviour is limited because they dont compare personalities to predict behaviour.
situationism
personality doesnt determine behaviour, situations do.
- don’t tend to measure situational variables that indicate how much situations affect behaviour.
- compare by looking at efe
Funder and Ozer study
- what did it do?
- compared prominent examples from social psych situations
- cognitive dissonance: $1 to lie = effect of incentive on behaviour, = -0.36
- bystander intervention: dramatic incident. more ppl present less likely to help = -0.38; greater hurry, less likely to help = -0.39
- Milgram: obedience r = .36-.42
conclusions of Funder and Ozer study
- argument against personality regarding the coefficient being too weak doesnt hold considering some iconic social psych study’s had similar coefficients
situational variables are important determinant but personality is also important.
are person perceptions erroneous?
can describe behaviour using personality.
- ppl have different personalities, as situation changes differences hold.
resolution to person-situation debate
situational variables: explain behaviour under specific circumstances
personality traits: explain how ppl act in general.
info gathered from personality varies btw situations and depends on situation.
2 types of situations?
weak: not as much influence, allows personality to be expressed
powerful/strong: forced to behave the same way regardless of personality. enforce behaviours
personality + life outcomes
personality affects LO that matter. aggregate of actions may influence
what is interactionism (re: s-p debate)
the principle that aspects of personality and of situations work together to determine behaviour; neither has an effect by itself, nor is one more important than the other.
three interactions within interactionism
- effect of personality may depend on situation,
- situation isn’t randomly populated (choose situation you’re in)
- ppl change situations by virtue of what they do in them
situationist side + deeper problems
Implies view of human nature
- people are free to do what they want, not bound by consistent personality.
- everybody is equal to everybody else. different outcomes are a function of the situations
personality side + deeper problems
- appreciates the unique aspects of every individual.
- allows ppl to be consistently themselves
what is personality assessment?
professional activity of numerous research, clinical and industrial psychologists, as well as a prosperous business.
- not only for psychologists
2 criteria for evaluation of personality assessment?
- agreement (validity)
2. accuracy (prediction)
examples of personality tests
- MMPI : b-data. clinical assessment
- California Psychological Inventory: non-clinical personality assessment
- sixteen personality factor questionnaire
- NEO personality inventory: s-data
- implicit association test
what is an omnibus test?
designed to measure wide range of different types of traits.
what is the IAT?
measures reaction time of words when paired with other words.
- unconscious knowledge measured + predicts aspects of behaviour
what are projective tests?
test that presents a participant with an ambiguous stimulus and asks the person to describe what they see.
- answers reveal inner psychological states/motivations of which the participant may be unaware
advantages of projective tests?
- hypothesis is interesting and reasonable
- responses are fascinating
- large number of clinicians swear by efficacy
disadvantages of projective tests?
data on validity is scare
- expensive + time-consuming
- can’t be sure exactly what the responses mean
- validity of the answer depends on the interpreter
what are objective tests?
a personality test that consists of a list of questions to be answered by the participant as T/F Y/N or numeric scale
why are objective tests not completely objective?
- less ambiguous + open to interpretation, but words may be misinterpreted
- ambiguity may be necessary for responses to imply personality
what is a commonality scale in objective tests?
consists of items that ppl tend to repond the same way.
- can detect if illiterate, or sabotaging based on answers in this section.
what is the hallmark of objective tests?
large number of items, very long
what is spearman-brown formula? what does it do?
use this formula to see if longer test will increase reliability
- relies on principle of aggregation that averages will cancel out.
- validity depends on the content of the test
what is the rational method?
- come up with items that seem directly, obviously and rationally related to what the test developer wishes to measure
- based on pre-existing theory or reflect whatever questions the researcher finds relevant
what is woodworth’s personality data sheet
116 q’s, all relevant to psych problems.
- list symptoms + ask do u have?
what are 3 ways to create an objective test?
- Rational Method
- Factor Analytic Method
- The Empirical Method
Rational Method: validity of the measurement depends on? (4)
- agreement on the meaning of items (btw test taker + developer)
- test taker makes an accurate self-assessment
- person must be willing to report the self-assessment accurately and without distortion
- all items must be valid indicators of what the tester is trying to measure
What is the core of the Factor analytic method?
analyzes patterns of correlations in order to extract mathematically defined factors, which underlie and help make sense of those patterns.
Factor analytic method: what is a factor?
property that makes items alike
when is factor analytic method used?
for test construction
- to determine # of fundamental traits
