What is factor analysis by Cattell?

Factor analysis is a method to find underlying correlations in large groups of data. He was a pioneer of using factor analysis to study behaviors. The factor analysis method is what led Cattell to identify the 16 individual traits that are central to his personality theory.

How did Cattell measure intelligence?

Cattell was interested in developing “culture free” intelligence tests based on non-verbal skills that would define a person’s general intelligence “g” (Spearman, 1904) irrespective of their social status, race, verbal ability or environmental experience. Cattell thus developed a culture-free test with seven sub-tests.

What is Cattell’s personality theory?

Cattell (1957) identified 16 factors or dimensions of personality: warmth, reasoning, emotional stability, dominance, liveliness, rule-consciousness, social boldness, sensitivity, vigilance, abstractedness, privateness, apprehension, openness to change, self-reliance, perfectionism, and tension ([link]).

What is the general factor theory of intelligence?

General intelligence can be defined as a construct that is made up of different cognitive abilities. These abilities allow people to acquire knowledge and solve problems. The idea is that this general intelligence influences performance on all cognitive tasks.

What did Cattell use?

Cattell’s Types of Data Cattell used three different types of data: life data (L-data), experimental data (T-data), and questionnaire data (Q-data). L-data is the kind of data that is collected from a subject’s everyday life, such as looking at people’s relationships or performance in school.

What is the greatest contribution of Cattell in personality development?

Psychologist Raymond Cattell is best known for his 16-factor personality model, developing the concept of fluid versus crystallized intelligence, and working with factor and multivariate analysis.

What personality test did Raymond B Cattell create?

The Sixteen Personality Factor Questionnaire
The Sixteen Personality Factor Questionnaire (16PF) is a self-report personality test developed over several decades of empirical research by Raymond B. Cattell, Maurice Tatsuoka and Herbert Eber.

Is fluid crystallized index the same as IQ?

Fluid intelligence is the ability to use logic and solve problems in new or novel situations without reference to pre-existing knowledge. Crystallized intelligence is the ability to use knowledge that was previously acquired through education and experience.

What IQ is average?

What Is an Average IQ Score? An average IQ score is between 85 and 115. 68% of IQ scores fall within one standard deviation of the mean. That means that the majority of people have an IQ score between 85 and 115.

How do we calculate an IQ?

The equation used to calculate a person’s IQ score is Mental Age / Chronological Age x 100. On most modern IQ tests, the average score will be 100 and the standard deviation of scores will be 15.

How does Cattell’s concept of personality traits differ from Allport’s view of traits?

How does Cattell’s concept of personality traits differ from Allport’s view of traits? Allport outlined three distinct categories of traits (source, central, secondary) which he referred to as personal dispositions, and common traits which were traits everyone shared.

Why did Cattell use factor analysis in his personality theory?

Cattell analyzed the T-data and Q-data using a mathematical technique called factor analysis to look at which types of behavior tended to be grouped together in the same people. He identified 16 personality traits / factors common to all people. Cattell made a distinction between source and surface traits.

What is Cattell’s theory of intelligence?

Cattell’s Theory of Intelligence. In psychology, fluid and crystallized intelligence (abbreviated Gf and Gc, respectively) are factors of general intelligence originally identified by Raymond Cattell. Fluid intelligence or fluid reasoning is the capacity to think logically and solve problems in novel situations, independent of acquired knowledge.

What is Raymond Cattell’s factor analysis method?

Raymond Cattell helped to advance this statistical method in the 1920s as a way to improve current models of measurement in psychology. Factor analysis is a method to find underlying correlations in large groups of data. It is a great tool for simplifying very large amounts of data to find common characteristics within.

What did Raymond Cattell contribution to psychology?

Personality Theory. Raymond Cattell made many contributions to psychology but is most renowned for his theory of personality. Cattell developed this theory later in his life, and his work in psychometric research and factor analysis culminated in this unique perspective on personality.
