Who is best known for work on the traits of introversion and extraversion?

• A. Carl Jung
• B. Sigmund Freud
• C. B. F. Skinner
• D. Jean Piaget

Answer: (A)

Introversion and extraversion describe how a person tends to source their energy and interact with the world. Carl Jung introduced these terms as two basic attitudes in his personality theory, with introverts turning energy inward and extraverts toward the outer world. This framework helps explain different social preferences, communication styles, and how people recharge. Among the options, Jung is the one whose work centers on these ideas; Freud focused on unconscious drives, Skinner on behavior and reinforcement, and Piaget on cognitive development. While later models (like the Big Five) include extraversion as a major trait, the original association of these terms with a personality framework comes from Jung.
