Raymond Cattel's 16 Personality Factor Trait Theory

• influenced McCrae and Costa in developing the five factor model.

• he defined personality as, it is something that predicts what a person would do in a situation.

• he used factor analysis to come up with the 16 PF.

• again, he used the words that describe a person’s personality, like what Allport does. However, the difference is how he turned it in questions. He gathered data using the questions.

Types of Data

1. L data - based on observations of other people. from secondary source

2. Q data - used to know the intended person. it is self-report. since it is self-report, the type of source is primary source (kung sino talaga ang tinatanong).

3. T data - used to measure performance such as intelligence and speed in responding.

Classification of Traits

• Source traits vs surface traits

• Common traits vs unique traits

• Temperament - how a person behaves

• Motivation - the reason or why a person behave

• Ability - how far or fast a person performs

Cattel’s stages of Personality Development

What is factor analysis?

• one begins by making specific observations of individuals. they are quantified.

  • parang similar dito yung sinabi sa book that cattel used inductive method, in which there are no preconcieved statements yet. nag-observe muna siya before concluding a theory.

  • dito papasok sa factor analysis yung method of correlation/ factor loading.
