Cattell trait theory
According to Cattell, Human behavior can be Determined on the basis of personality traits. He created a taxonomy of 16 different personality traits that was used to describe difference between people’s personality. He used a technique called factor analysis and Shorted down the list of 16 factors. Each person contains all these 16 traits to a certain degree, but they might be high in some traits and low in others.

Three data types are collected –
- L- Data ( Life Data) – It is obtained by gathering life history of person (personal records)
- Q- Data ( Questionnaire data) – It is obtained by asking people to describe themselves in response to a set of standard questions (Multiple choice, true/false).
- T-Data (Experiment data) – It is obtained by asking people to take various tests (projective, physical, reaction times) in which the purpose of the test isn’t obvious. It involves the creation of Special situations in which the person’s behavior may be objectively scored
Raymond Bernard Cattell has identified two type of traits general traits which are those possessed by everyone to a certain degree or possessed by all and Specific traits which are those typical of only one person.
Cattell, by adopting a method called factor analysis has recognized 16 ‘source traits’ as building blocks of our personality. These factors are known as Sixteen Personality Factor (16PF) Questionnaire and this 16 traits describe in below–
