CATTEL'S THEORY OF PERSONALITY - ratheeshthapasya



Cattel’s theory of personality
Reymond B Cattel is another ardent propounder of the trait theory of personality
For him basic structural element is the trait.  He defined a trait as a structure of personality inferred from the behavior in different situations.
He classified traits in four categories
1.   Common traits
Certain traits which are found widely distributed in general population
It may be honesty, cooperation, aggression

2.   Unique traits
These traits are possessed by particular persons as temperamental traits, emotional reaction, and energy etc.
These are distinctive and unique to a person
These traits act as the basis for individual difference.

3.   Surface traits
Traits which can be easily recognized by overt manifestation of behavior like curiosity, tactfulness, integrity, dependability

4.  Source traits
Those Traits which determine the behavior of the individual.
These are underlying structures or sources that determine behavior such as dominance and emotionality.
These traits cannot be seen directly or externally in the behavior of an individual.
Cattell considers source trait is more important than surface traits

Cattell compiled a list of 17000 personality traits & develops subsequent modifications through his psychological research. He found 35 surface traits.
Later Through the process of factor analysis, he identified 16 source traits, which are called 16 personality factors.

Cattell postulated his formula for the analysis of behaviour / response
R = S1 T1+S2 T2 +S3 T3+…....+Sn Tn
 R = Behaviour / Response
T = Source Trait
S = the importance of the trait for that response


Through factor analysis approach, he determined the contribution of hereditary and learning factors in the development of traits in the individual.  He emphasized the importance of interaction between hereditary and environment influences in personality development.

Common feature of trait theories
Consistency – traits are consistent in an individual’s behavior. They are not temporary dispositions. They are enduring characteristics of the individual.
Dimensions- there is agreement regarding the various dimensions of the traits as source traits, surface common traits etc.  Traits vary in breadth and generality.
Dispositions- traits fluctuate in a person’s positions with respect to a disposition

Evaluation of trait theory
Trait theory is a straight forward approach to the measurement of personality as it employs appropriate methods like correlation and factor analysis
Weaknesses
 No agreement among the psychologists as regards the use of the terms
Trait is not permanent or static characteristic of the individual because personality is undergoing the perpetual change.
Another difficulty is the quantification of human traits. There is no suitable measuring tool.
