Cattellféle

Cattellféle refers to a family of instruments developed by psychologist Raymond Cattell. These instruments were designed to measure various aspects of personality and intelligence. Cattell's work was highly influential in the field of psychometrics and led to the development of numerous tests based on his theoretical frameworks.

One of the most well-known Cattellféle instruments is the Sixteen Personality Factor Questionnaire, often abbreviated as the 16PF. This questionnaire assesses 16 primary personality traits that Cattell identified through factor analysis of questionnaire data and life record data. The 16PF has been widely used in clinical, counseling, educational, and occupational settings. Another significant contribution is Cattell's theory of fluid and crystallized intelligence, which he measured using the Culture Fair Intelligence Tests. These tests were designed to minimize the influence of cultural background and educational experience, aiming to provide a more accurate assessment of innate cognitive abilities. The Cattellféle instruments, in their various forms, represent a systematic attempt to quantify and understand the complex structure of human personality and intellect. They are characterized by their basis in empirical research and their application of statistical methods, particularly factor analysis, to identify underlying dimensions of psychological constructs.
