Chapter 4-5: traits, needs, motives Flashcards
The trait approach
builds on how people intuitively think and talk about each other by translating the natural, informal language of personality into a formal psychology that measures traits and uses them to predict and explain human behaviour
Personality psych and everyday human observations are
not so different
Components of the trait approach
- based on empirical research that mostly uses correlational designs (trait predicts behaviour)
- focuses exclusively on individual differences
trait measurements are _______, not ________
ordinal
rational
ordinal data
ordinal data is a statistical data type consisting of numerical scores that exist on an ordinal scale, i.e. an arbitrary numerical scale where the exact numerical quantity of a particular value has no significance beyond its ability to establish a ranking over a set of data points.
can’t have 0
Rational scale
Rational scale
measurements compared in terms of ratios
ex. could have a 0
people are inconsistent
there will be numerous exceptions to people’s general or usual way of behaving
situations are also important
older people are more ______ in their ________ than _________
consistent
personalities
younger people
older adults are more stable in general (i.e. have an established identity, career…
Person-situation debate
Walter Mischel
which is more important for determining what people do? The people? or the Situation?
- traits are poor predictors of behaviours
- situations are better when accounting for differences in behaviour
- personality assessments and everyday intuitions about personality are fundamentally flawed
Predictability
test the usefulness of a personality trait is whether you can use it to predict behaviour
Situationist argument of predictability
predictive capacity of personality is limited
at best, correlations between personality traits and behaviour are about 0.3 (0.4 NIsbett)
Situationist argument of predictability: responses!
- unfair literature review
- focused on studies that obtained disappointing results rather than the numerous ones with impressive findings
- many studies were methodologically flawed, yet still found significant correlations - we can do better
- weak findings merely imply that psychologists can do much better reattach outside the lab
- some people (and behaviours) might be more consistent than others
- focus on behavioural trends instead of single actions at particular moments - 0.4 is not small
- comparison with an absolute standard: a correlation of 0.4 means that a prediction of behaviour based on personality trait is likely to be accurate 70% of the time
- could also compare with a relative standard: ability of situational variables to predict behaviour
Situationism
personality does not determine behaviour, situations do!
But:
- often, the impact of the situation is presumed to be what is left over after subtracting the correlation of personality to behaviour
- don’t tend to measure situational variables in a way that indicates precisely how or how much situations affect behaviour
- can compare by looking at effect sizes
Funder and Ozer (1983)
compared prominent examples from social psychology of the power of situations to shape behaviour
- Festinger and Carlsimth (1959) cognitive dissonance
- darley and latane (1968) bystander interventiom
- milgran (1975) obediance
2 possible conlcuions
situational variables are important
personality variables are also important
aggregate the results
Festinger and Calsmith (1959)
Cognitive dissonance
subjects paid one dollar found the study more interesting, because of the cognitive dissonance!
r = -0.36
Darley and Latane (1968)
Bystander intervention
Bystander intervention
r = -0.38
r= -0.39
less likely to help if others are around
Milgram 1975 obedience
r = 0.42, r = 0.36
2 variables:
- isolation of the victim - further away the obedience was higher than when the victim was in the same room
- proximity of the researcher - closer they are the more likely to obey
Are person perceptions erroneous?
despite the situations critique, the effect of the personality on behaviour do seem sufficient to be perceived accurately
people really do act differently from each other
The resolution of the situationist debate?
- situational variables are relevant to how people will act under specific circumstances
- personality traits are better for understanding how people act in general
- in the long run, personality affects many important outcomes
(people maintain their personalities even as they adapt their behaviour to particular situations)
Quality of information
- the value of info you can gather about a person’s personality can vary from situation to situation
(weak vs. strong situations)
common intuition is that you might be able to learn something extra about a person if you observe them in a stressful or emotionally arousing situation (may be correct)
Personality and life outcomes
personality affects life outcomes that matter to people (i.e. health, career satisfaction)
may affect so many outcomes because it is present throughout life
Interactionism
the principle that aspects of personality and or situations work together to determine behaviour
neither has an effect by itself, not is one more important than the other
the effect of the personality variable may depend on the situation or vice versa
situations are not randomly populated, people change situations by virtue of what they do in them
Interactionism: students and caffeine
students performed worse after lots of caffeine
interactionism and hostile people/white noise
when hostile people were allowed to blast white noise at each other, they kept turning up the volume, this did not happen with the non-hostile people
hostile people create a more hostile environment for themselves
Situationist side of interactionism
people are free to do what they want, rather than having their behaviour influenced by their consistent personality
everybody is equal to everybody else, and different outcomes are a function of the situations in which they find themselves
personality side of interactionism debate
appreciates the unique aspects of every individual
allows people to consistently be themselves
personality assessment
professional activity of numerous research, clinical and industrial psychologists, as well as a prosperous business
not restricted to psychologists
two criteria for evaluation (validity or accuracy): agreement and prediction

Personality test examples
MMPI California Psychological Inventory Sixteen personality factor questionnaire NEO personlaity inventory Implicit association test
many are omnibus tests; theres measure just one trait
omnibus
omnibus: measure wide range of traits
personality tests mainly take _____ data, but some use ______ data
S (results = how you define yourself)
B
(preferring to shower = emphathic response
