Step-by-step explanation:
The major difference between the Cattell and Eysenck approaches to developing measures of personality lies in the number of factors they identify. Cattell identified 16 factors or dimensions of personality, while Eysenck focused on two specific dimensions: extroversion/introversion and neuroticism/stability.
By narrowing down the list of traits to 16 factors, Cattell aimed to capture a comprehensive picture of an individual's personality. On the other hand, Eysenck believed that extroversion/introversion and neuroticism/stability were the fundamental dimensions that could explain most of the variations in personality.
While Cattell's approach is more detailed and comprehensive, Eysenck's approach is more simplified and focused on the basic dimensions of personality.
