LECUTRE 9: Week 5 CONTEMPORARY TRAIT TAXONOMIES
OVERVIEW:
PART I : Introduction to the Big Five taxonomy
PART I I: Emotional and Intrapersonal Domains
PART I II: Core Feature of Extraversion
PART I: Introduction to the Big Five taxonomy
In most cultures, not only English, whenever we bring together enough words such
that they represent the broad range of words we use to describe peoples traits, we
typically find 5 dimensions of difference
Called the 5 factor model or The Big 5
We know people arent exactly the same from one situation to the next but we know
that they leave some sort of signature (behavioural signature) and that there are
some sort of consistencies in the way that they behave
In the domain of personality psychology this is most the widely studied of all
concepts the trait concept
The Five Factor Model (the big 5)
Common measures of the big 5 are:
1) NEO-PI-R (costa and macrae, 1992)
2)The Big Five Inventory (john et al., 1991)
3)Recently Gosling et al (2003) demonstrated that the 5-factor model could be
reliably assessed by as few as 10 items
All the above measures are reliable, robust questionnaires to help us assess the Big
5. They are all widely used today

1) NEO-PI-R
Originally developed in the late 70s (more so in the 80s).
the first three letters are NEO b/c the first 3 traits Identified were neuroticism,
extroversion and openness.
Later on expanded to incld agreeableness and conscientiousness and then was
completed and revised and is now known as the Revised NEO inventory/ NEO-PI-R
Its a 240 item inventory that not only assesses the 5 domains but also 6 traits
(facets) associated with each of the 5 traits So altogether it measures 30 traits and
5 domains
Takes about 30-45 min to complete which is a long time so participants arent
usually asked to do it and they invented a new questionnaire: the NEO-FFI (NEO
Five Factor Inventory)
NEO-FFI:
60 items long, so its nice and brief and can be completed in 15 min
But every time you administer for it youre charged so researchers cloned this
questionnaire to develop the most common/famous questionnaire: the Big Five
Inventory
2) Big Five Inventory aka BFI
44 item measure so its administered pretty quickly (10min)
Resulting scores = reliable and valid
One of the more widely used instruments
3) 10 item questionnaire
This isnt the best thing to do but it has been shown that if you need to do so you can
measure the Big Five reliably from at least 10 items (2 per domain)
Takes about 2-3min
All of these measures have the same 5 constructs of interest in common
Neuroticism (N)
A broad dimension of individual differences relating to the readiness to experience
distress and other negative affects

People who are high on this trait more readily experience a wide range of emotional
and somatic (related to body) complaints.
Report feeling vulnerable, self-conscious, worrisome, quick to anger
Facets: anxiety, angry hostility, depression, self consciousness, impulsiveness,
vulnerability
A good way is to measure how quick you are to regulate your negative moods to find
out if youre neurotic
If youre high in this dimension, you are least able to regulate your negative moods
like sadness, worry, anger
On the other end of this dimension is emotional stability > people who are best able
to regulate their negative moods
Neurotic people have a troubled emotional life
Correlates of N:
Relationship difficulties
othose high in N have lower levels of satisfaction in relationships, marriage
and higher rates of divorce
othe burdens of close relationships are really hard for these people to bear
othey are highly anxiously attached and not very securely attached (all the
additional stress N people feel (abandonment issues etc.) places burden on
their partners in the relationship and causes burden)
negative affect (hallmark of neurotic people)
orelates to all negative emotional states (depression, anxiety, anger,
irritability)
oif you were to regularly measure a persons mood over time (both positive and
negative) you would find that the trait of N was the best predictor of how
negative ones overall mood was
opeople high on N scale report high feelings of negative affect
N however is not related to the frequency of positive affect
This is weird b/c positive and negative moods are highly negatively correlated (if
youre feeling negatively then you cant be feeling positive affect)
oThis is ONLY for short time periods those
