Step-by-step explanation:
Carl Jung was a Swiss psychiatrist and the protégé of Freud. He developed his own theory called analytical psychology, which focuses on balancing conscious and unconscious thought within one's personality. Jung proposed two attitudes or approaches toward life: extroversion and introversion. Extroverts gain energy from being outgoing and socially oriented, while introverts derive energy from their inner psychic activity. Jung also proposed four functions: thinking, feeling, sensation, and intuition. These functions represent different ways in which individuals perceive and process information.
