Question

Who proposed the Introversion-Extroversion dimension of Personality?

• A. Jung
• B. Cattel
• C. Eysenck
• D. Allport

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
The question asks to identify the theorist who originally introduced the concepts of introversion and extroversion as a central dimension of personality.
Step 2: Detailed Explanation:
(A) Carl Jung: In his book "Psychological Types" (1921), Carl Jung introduced introversion and extroversion as the two major attitudes or orientations of personality. He described extroversion as an outward turning of psychic energy (libido) and introversion as an inward turning. This was a foundational concept in his theory of analytical psychology.
(C) Hans Eysenck: Eysenck later developed a major personality theory that included Introversion-Extroversion as one of its three superfactors (along with Neuroticism and Psychoticism). However, he built upon Jung's original concept, he did not propose it first.
(B) Raymond Cattell: Cattell's theory is known for the 16 Personality Factors (16PF), which includes a factor related to introversion/extroversion but he did not originate the dimension itself.
(D) Gordon Allport: Allport was a trait theorist known for his concept of cardinal, central, and secondary traits.
Step 3: Final Answer:
While Eysenck's work heavily features this dimension, Carl Jung was the one who originally proposed the introversion-extroversion dimension of personality.
