Discuss psychological differences between people
Personality refers to enduring, relatively broad psychological
differences between people, excluding cognitive abilities
What are the 4 dispositions
*Personal identity & self-concept
*Social communication & gossip
*Person perception
*Stereotypes
Discuss Prentice, 1990
Personality & self-concept
“Describe yourself”
Discuss Robert Dunbar
Robin Dunbar argued that
human intelligence evolved to
handle the complexities of
group life
Much of our social
communication aims to learn
what others are like: their
personalities
Discuss Person perception
Person perception is judging other people’s personalities
‘correspondence bias’
Discuss Stereotypes
Stereotypes are largely made up of personality traits
believed (rightly or wrongly) to be associated with social
groups
What is Personality psychology’s place in the field
Dedicated to understanding the
‘whole person’
*Focuses on differences between
people, not shared mechanisms and
processes
*Related to clinical psychology
*Places emphasis on factors intrinsic
to the person
◦Contrast with social psychology
◦The person versus the situation
How should we describe personality?
For a scientific psychology of personality …
*We need a descriptive unit
*We need a classification or ‘taxonomy’ of these units
Discuss Personality traits
The simplest descriptive unit is the ‘trait’
A trait is a consistent pattern of behaviour, thinking or feeling
◦ Relatively stable over time
◦ Relatively consistent across situations
◦ Varying between people
◦ Dispositional
Trait vary in generality or ‘_______’: some are ______, others _______
bandwidth, broad, narrow
How are traits organised?
One theory
“People come in four types: the pomegranate (hard on the outside, hard on the inside), the walnut (hard-soft), the prune (soft-hard) and the grape (soft-soft)”
Muhammad Ali
Structure of personality traits
Where do we start in developing a
scientific taxonomy of personality?
*Survey the traits that are encoded
in language
*This is the “lexical approach”
*It assumes that important
distinctions for describing people
are incorporated in everyday
speech
Discuss Allport & Odbert, 1936
1936 attempt to survey the ‘trait universe’
*Searched a large dictionary for words that could
describe differences between people
*18,000 out of 550,000
*These were then filtered
Discuss Raymond Cattell
4,504 trait words is still too many
*Many were synonyms
*Cattell progressively reduced the set
What are Cattell’s 16 factors?
Reserved ↔Outgoing
Stable ↔ Neurotic
Expedient ↔Conscientious
Shy ↔Venturesome
Tough-minded ↔ Tender-minded
Trusting ↔ Suspicious
Practical ↔Imaginative
Forthright ↔Shrewd
Less intelligent ↔More intelligent
Humble ↔ Assertive
Sober ↔ Happy-go-lucky
Placid ↔ Apprehensive
Conservative ↔Experimenting
Conforming ↔Independent
Undisciplined ↔ Controlled
Relaxed ↔Tense
Problem with Cattel’s 16 factors?
Still too many factors?
Cattell’s 16 factors were still correlated
Different factors might both reflect a single underlying “super-factor”
For example…
Reserved ↔ Outgoing
Shy ↔Venturesome
Or…
Stable ↔Neurotic
Placid ↔Apprehensive
Relaxed ↔Tense
