Textbook Chapter 7 Flashcards
trait theorists focus on…
identifying relatively stable features of personality
that distinguish you from other people
trait theory started off with…
typology systems
ie. Greek typology system
Greek typology system
divided all people into 4 types
- sanguine (happy)
- melancholic (unhappy)
- choleric (temperamental)
- phlegmatic (apathetic)
physique-based typology
diffs in physical appearance translated into diffs in personality
- endomorphic (obese)
- mesomorphic (muscular)
- ectomorphic (fragile)
typology systems have…
largely been abandoned
faulty assumptions:
- assume everyone fits into one personality category
- and that each category member is basically alike
- and that the behaviour of all people in one category is distinct from those in another category
3 arguments of trait psychologists
- any personality trait can be illustrated on a continuum (from extremely low in trait to extremely high in trait)
- any person can be placed somewhere along the continuum for every trait
- if we measure a large number of people and place their scores on the continuum, would find all scores create a normal distribution
trait
dimension of personality used to categorize people according to degree to which they manifest a particular characteristic
2 important assumptions of trait approach
- personality traits are relatively STABLE OVER TIME
(not to say that personalities don’t change - research has found they develop from adulthood through to old age, but changes are gradual)
- personality traits are relatively STABLE ACROSS SITUATIONS
trait researchers aren’t interested in what? what do they look at instead?
aren’t interested in PREDICTING behaviour in GIVEN SITUATIONS
they focus instead on predicting how people who score within a certain segment of the continuum TYPICALLY BEHAVE
rather than singling out individuals, they try to find out how the AVERAGE PERSON on EACH SCORE of the continuum would behave
significance of person’s score on trait measure lies in…
how it compares with other people
have schools of psychotherapy emerged from trait approach to personality?
no (unlike the psychoanalytic, cognitive, behaviourist approaches)
its findings are more useful to therapists making diagnoses and charting therapy progress
more ACADEMIC than therapeutic implications
Gordon Allport quote on dispositions
“dispositions are never wholly consistent. what a bore it would be if they were - and what chaos if they were not at all consistent”
book published by Gordon and Floyd Allport
Personality Traits: Their Classification and Measurement
Gordon Allport
he developed the first recognized work on traits
taught first college course on personality in the US
he acknowledged the limitations of trait concept from the beginning
Gordon Allport: from beginning, he acknowledged…
limitations of the trait concept
- accepted that behaviour is influenced by variety of ENVIRONMENTAL factors
- recognized that traits AREN’T USEFUL in PREDICTING what a single individual will do
Allport’s 2 research strategies when investigating personality
- nomothetic approach
- idiographic approach
nomothetic approach
assumes all people can be described along SINGLE DIMENSION according to their LEVEL of a trait
each person is tested to see how their score for a given trait COMPARES with scores of other participants
nomothetic approach tests what kind of traits?
COMMON traits
^ those that presumably apply to everyone
Allport thoughts on nomothetic approach
that it’s INDISPENSABLE for understanding human personality
idiographic approach
identify the UNIQUE COMBO of traits that BEST ACCOUNTS for personality of a single individual
5-10 traits that best describe one’s personality are called CENTRAL TRAITS
also CARDINAL TRAITS
central traits
in the idiographic approach, the 5-10 traits that BEST DESCRIBE someone’s personality
number of central traits varies from person to person
cardinal trait
rare individuals have personalities dominated by a SINGLE TRAIT
when a behaviour becomes synonymous with an individual
ie. Machiavellian, Homeric, Don Juans
advantage of idiographic approach
the PERSON, not the researcher, DETERMINES what traits to examine
con of nomothetic approach
traits selected by the investigator might be central for some people, but only SECONDARY for others
test score of someone’s sociability isn’t of great value when sociability isn’t a central trait of a person
won’t result in a great assessment of their personality
Allport was also interested in the concept of…
the “self”
particularly the process by which children develop a sense of themselves
Gordon Allport life dates
1897-1967
Gordon Allport early life
born in Montezuma, Indiana
3 older brothers
didn’t fit in as a kid
“I was quick with words, poor at games”
followed his older bro to Harvard, and studied psychology just like him
Gordon Allport achievements
pioneered field of trait psychology - although faced criticism and opposition at first
elected president of the American Psychological Association
received the prestigious Distinguished Scientific Contribution Award
editor of the Journal of Abnormal and Social Psychology
Henry Murray’s approach to personality was a blend of…
psychoanalytic and trait concepts
interacted with Jung early on in his career - so his work mentions the unconscious a lot
came up with the Thematic Apperception Test (TAT)
Murray called his approach…
personology
Murray identified what as the basis of personality?
NEEDS
psychogenic needs, especially
psychogenic needs
what Murray considered the basic elements of personality
a “readiness to respond in a certain way under certain given conditions”
postulated to be UNCONSCIOUS
27 of these needs
examples of psychogenic needs
need for order
need for dominance
need for achievement
according to Murray, each of us can be described…
in terms of a PERSONAL HIERARCHY OF NEEDS
ie. if you have a strong need for lots of close friends, you are high in need for affiliation
importance of your needs aren’t so much how they compare to needs of other people, but HOW INTENSE it is compared to YOUR OTHER NEEDS
achievement vs affiliation needs example
say you have a big test tmrw, but your friends are having a party
if your achievement need is higher than your affiliation need, you’ll probably hit the books instead of the party
the press
the situation that determines whether or not a need is activated
needs are only activated in certain situations
ie. need for order will only be activated if your room is really messy
Murray’s principle contributions to field of psychology
- TAT
- the research stimulated by his theory (ie. his psychogenic needs)
Henry Murray life dates
1893-1988
Henry Murray background
walked out of his first psych lecture because he was bored
got a medical degree from Columbia
then went to Cambridge to study biochem
then exposed to Carl Jung’s writings
received formal psychoanalytic training at Harvard and taught there until retirement
he was a stutterer
also worked for the Office of Strategic Services (forerunner to the CIA) - applied personality in selection of undercover agents
also a literary scholar
Raymond Cattell
another pioneer of the trait approach
had yet another approach to personality
borrowed approach from the sciences (his first degree was in chemistry) - FACTOR ANALYSIS
much of Cattell’s work was dedicated to…
determining just HOW MANY basic personality traits there are
there are hundreds, but some of them are certainly related
ie. being sociable and extraverted aren’t entirely separate
factor analysis
Cattell’s approach
statistical technique
compares scores of traits from many people
you might find that friendliness and tenderness scores are highly correlated
if a person scores high on one test, you can predict with some confidence that the person also will score high on the other test
looking at pattern of correlation coefficients, might discover that tests tend to CLUSTER into groups
ie. five of the traits may correlate with one another, but not with the five other tests
although you measured 10 traits, reasonable to say you really measured 2 LARGER PERSONALITY DIMENSIONS
factor analysis: example of 2 groups with correlated traitst
group 1:
- aspiration
- determination
- endurance
- persistence
- productivity
group 2:
- compassion
- cooperativeness
- friendliness
- kindliness
- tenderness
Cattell, by using factor analysis, did what?
by analyzing data from various sources with factor analyses
he attempted to determine HOW MANY of these basic personality elements (source traits) exist
source traits
basic traits that make up human personality
what Cattell was after
