- [Girish] Hi, this is Girish Kishnani

0:00:02.550,0:00:04.920
and you are watching "5 Minute Learnings."

0:00:04.920,0:00:08.190
Welcome to the eighth video[br]in the series on personality.

0:00:08.190,0:00:11.760
Today, we will explore the[br]trait theories of personality.

0:00:11.760,0:00:14.790
The trait theory of personality[br]suggests that people have

0:00:14.790,0:00:17.400
certain basic traits or dispositions,

0:00:17.400,0:00:19.980
and it is the strength and[br]intensity of those traits

0:00:19.980,0:00:23.070
that account for personality differences.

0:00:23.070,0:00:24.990
The trait approach to personality

0:00:24.990,0:00:27.090
is one of the major theoretical areas

0:00:27.090,0:00:28.830
in the study of personality.

0:00:28.830,0:00:31.890
A trait is a consistent,[br]stable characteristic

0:00:31.890,0:00:35.070
that causes individuals[br]to behave in certain ways.

0:00:35.070,0:00:37.290
It varies from person to person.

0:00:37.290,0:00:41.010
The outlook towards personality[br]and how traits are defined

0:00:41.010,0:00:42.720
has evolved over time.

0:00:42.720,0:00:45.360
Unlike many other theories of personality,

0:00:45.360,0:00:48.420
such as psychoanalytic[br]or humanistic theories,

0:00:48.420,0:00:50.370
the trait approach to personality

0:00:50.370,0:00:53.550
is focused on differences[br]between individuals.

0:00:53.550,0:00:56.310
The combination and[br]interaction of various traits

0:00:56.310,0:00:58.260
is unique to each person.

0:00:58.260,0:01:00.660
Trait theory is focused on identifying

0:01:00.660,0:01:04.110
and measuring these individual[br]personality characteristics.

0:01:04.110,0:01:05.580
If someone asked you to describe

0:01:05.580,0:01:07.410
a close friend's personality,

0:01:07.410,0:01:09.420
what kind of things would you say?

0:01:09.420,0:01:11.340
A few things that might come to mind

0:01:11.340,0:01:14.550
are descriptive terms[br]such as outgoing, kind,

0:01:14.550,0:01:16.050
and even-tempered.

0:01:16.050,0:01:19.110
All of these represent personality traits.

0:01:19.110,0:01:20.190
The first trait theory

0:01:20.190,0:01:24.750
was proposed by psychologist[br]Gordon Allport in 1936.

0:01:24.750,0:01:27.480
Allport found that one[br]English language dictionary

0:01:27.480,0:01:29.730
contained more than 4,000 words

0:01:29.730,0:01:32.340
describing different personality traits.

0:01:32.340,0:01:35.400
He categorized these[br]traits into three levels:

0:01:35.400,0:01:38.160
cardinal, central, and secondary.

0:01:38.160,0:01:39.330
Cardinal traits.

0:01:39.330,0:01:41.460
Allport suggested that cardinal traits

0:01:41.460,0:01:42.930
are rare and dominating,

0:01:42.930,0:01:45.150
usually developing later in life.

0:01:45.150,0:01:47.670
They tend to define a[br]person to such an extent

0:01:47.670,0:01:50.940
that their names become[br]synonymous with their personality.

0:01:50.940,0:01:53.220
Examples include descriptive terms

0:01:53.220,0:01:56.370
such as narcissistic and Christ-like.

0:01:56.370,0:01:57.540
Central traits.

0:01:57.540,0:01:59.160
These general characteristics

0:01:59.160,0:02:01.950
form basic personality foundations.

0:02:01.950,0:02:04.290
While central traits are not as dominating

0:02:04.290,0:02:05.670
as cardinal traits,

0:02:05.670,0:02:07.680
they describe the major characteristics

0:02:07.680,0:02:09.900
you might use to describe another person,

0:02:09.900,0:02:13.080
such as intelligent, honest, shy,

0:02:13.080,0:02:15.930
and anxious refer to central traits.

0:02:15.930,0:02:17.250
Secondary traits.

0:02:17.250,0:02:19.500
Secondary traits are sometimes related

0:02:19.500,0:02:21.570
to attitudes or preferences.

0:02:21.570,0:02:24.360
They often appear only[br]in certain situations

0:02:24.360,0:02:26.790
or under specific circumstances.

0:02:26.790,0:02:29.820
Some examples include[br]public speaking anxiety

0:02:29.820,0:02:32.730
or impatience while waiting in line.

0:02:32.730,0:02:35.550
Cattell's 16-factor personality model.

0:02:35.550,0:02:37.140
Trait theorist Raymond Cattell

0:02:37.140,0:02:39.660
reduced the number of[br]main personality traits

0:02:39.660,0:02:44.460
from Allport's initial list[br]of over 4,000 down to 171.

0:02:44.460,0:02:47.730
He did so primarily by[br]eliminating uncommon traits

0:02:47.730,0:02:50.070
and combining common characteristics.

0:02:50.070,0:02:53.310
Next, Cattell rated a[br]large sample of individuals

0:02:53.310,0:02:56.190
for these 171 different traits.

0:02:56.190,0:02:59.730
Using a statistical technique[br]known as factor analysis,

0:02:59.730,0:03:02.100
he identified closely related terms

0:03:02.100,0:03:03.720
and eventually reduced his list

0:03:03.720,0:03:06.300
to 16 key personality traits.

0:03:06.300,0:03:09.030
Among them are dominance, perfectionism,

0:03:09.030,0:03:11.280
reasoning, and self-reliance.

0:03:11.280,0:03:13.860
According to Cattell, these 16 traits

0:03:13.860,0:03:16.650
are the source of all human personalities.

0:03:16.650,0:03:17.700
He also developed

0:03:17.700,0:03:20.700
one of the most widely used[br]personality assessments,

0:03:20.700,0:03:23.910
the 16 Personality Factor Questionnaire.

0:03:23.910,0:03:26.400
Eysenck's three dimensions of personality.

0:03:26.400,0:03:28.470
British psychologist Hans Eysenck

0:03:28.470,0:03:31.770
believed that personality[br]has a biological basis,

0:03:31.770,0:03:33.780
developing a model of personality

0:03:33.780,0:03:36.270
based on just three universal traits.

0:03:36.270,0:03:38.250
Introversion/extroversion.

0:03:38.250,0:03:40.410
Introversion involves directing attention

0:03:40.410,0:03:41.970
to inner experiences,

0:03:41.970,0:03:45.180
while extroversion relates[br]to focusing attention outward

0:03:45.180,0:03:47.400
onto other people and the environment.

0:03:47.400,0:03:51.180
A person high in introversion[br]might be quiet and reserved,

0:03:51.180,0:03:53.880
while an individual high in extroversion

0:03:53.880,0:03:56.460
might be sociable and outgoing.

0:03:56.460,0:03:59.250
Neuroticism/emotional stability.

0:03:59.250,0:04:01.410
This dimension of Eysenck's trait theory

0:04:01.410,0:04:04.710
is related to moodiness[br]versus being even-tempered.

0:04:04.710,0:04:08.250
The trait of neuroticism refers[br]to an individual's tendency

0:04:08.250,0:04:10.320
to become upset or emotional,

0:04:10.320,0:04:12.450
while stability refers to the tendency

0:04:12.450,0:04:14.880
to remain emotionally constant.

0:04:14.880,0:04:15.960
Psychoticism.

0:04:15.960,0:04:19.350
Later, after studying[br]individuals with mental illness,

0:04:19.350,0:04:22.920
Eysenck added a personality[br]dimension he called psychoticism

0:04:22.920,0:04:24.330
to his trait theory.

0:04:24.330,0:04:26.370
Individuals who are high in this trait

0:04:26.370,0:04:28.920
tend to have difficulty[br]dealing with reality

0:04:28.920,0:04:31.170
and may be antisocial, hostile,

0:04:31.170,0:04:34.110
non-empathetic, and manipulative.

0:04:34.110,0:04:36.300
Five factor model of personality.

0:04:36.300,0:04:38.400
Both Cattell's and Eysenck's theories

0:04:38.400,0:04:41.280
have been the subject of[br]considerable research.

0:04:41.280,0:04:43.380
This has led some theorists to believe

0:04:43.380,0:04:45.750
that Cattell focused on too many traits

0:04:45.750,0:04:48.240
while Eysenck focused on too few.

0:04:48.240,0:04:50.370
As a result, a new trait theory,

0:04:50.370,0:04:53.970
often referred to as the[br]Big Five theory, emerged.

0:04:53.970,0:04:56.220
This five-factor model of personality

0:04:56.220,0:04:58.620
represents five core traits that interact

0:04:58.620,0:05:00.450
to form human personality.

0:05:00.450,0:05:02.400
While researchers often disagree

0:05:02.400,0:05:05.100
about the exact labels for each dimension,

0:05:05.100,0:05:08.130
they are commonly[br]described as agreeableness:

0:05:08.130,0:05:10.950
level of cooperation[br]and caring for others,

0:05:10.950,0:05:12.300
conscientiousness:

0:05:12.300,0:05:14.340
level of thoughtfulness and structure,

0:05:14.340,0:05:15.390
extroversion:

0:05:15.390,0:05:18.360
level of socialness and[br]emotional expressiveness,

0:05:18.360,0:05:20.970
neuroticism: level of mood stability

0:05:20.970,0:05:22.590
and emotional resilience,

0:05:22.590,0:05:25.713
openness: level of[br]adventure and creativity.

0:05:26.580,0:05:29.310
Some of the most common[br]criticisms of trait theory

0:05:29.310,0:05:30.930
center on the fact that traits

0:05:30.930,0:05:33.330
are often poor predictors of behavior.

0:05:33.330,0:05:35.310
While an individual may score high

0:05:35.310,0:05:37.500
on assessments of a specific trait,

0:05:37.500,0:05:41.430
they may not always behave[br]that way in every situation.

0:05:41.430,0:05:43.500
Another problem is that trait theories

0:05:43.500,0:05:45.240
do not address how or why

0:05:45.240,0:05:49.023
individual differences in[br]personality develop or emerge.

0:05:49.920,0:05:53.340
We all have certain traits[br]that dominate our personality

0:05:53.340,0:05:56.190
along with various[br]permutations and combinations

0:05:56.190,0:05:58.800
that can arise in different situations.

0:05:58.800,0:06:01.350
Also, our traits can change over time

0:06:01.350,0:06:03.540
and be shaped by our experiences.

0:06:03.540,0:06:04.950
That's all for today.

0:06:04.950,0:06:07.320
In the next video, we[br]shall continue to explore

0:06:07.320,0:06:09.720
more related topics on trait theories.
