Introvert and Extrovert Personality Two Classic Studies in Psychology includes two early 20th century studies by psychoanalysts Carl Gustav Jung and Beatrice Moses Hinkle. Both studies describe extraversion and introversion as central characteristics of individual psychological types, and go on to detail extrovert and introvert personality traits.Carl Jung (1875-1961), a renown Swiss psychoanalyst, wrote pioneering studies in the field of psychology. His wide-ranging body of work has left a lasting cultural influence on Western thought. The first classic study, Jung’s article General Description of the Types, was originally written in 1921. In it Jung coins the terms “introverted and extraverted.” The article also appears as Chapter 10 of his influential Psychological Types (1921).Beatrice M. Hinkle (1874-1953), an American psychoanalyst and noted feminist, published The Re-Creating of the A Study of Psychological Types and Their Relation to Psychoanalysis (1923) in which she calls man’s real goal the “achieving of an individuation.” In a 1924 article, the New York Times commended her book, noting “She has detoured from beaten paths and blazed trails of her own.” A Study of Psychological Types, from her book The Re-Creating of the Individual is the second classic study presented.
Carl Gustav Jung (/jʊŋ/; German: [ˈkarl ˈɡʊstaf jʊŋ]), often referred to as C. G. Jung, was a Swiss psychiatrist and psychotherapist who founded analytical psychology. Jung proposed and developed the concepts of extraversion and introversion; archetypes, and the collective unconscious. His work has been influential in psychiatry and in the study of religion, philosophy, archeology, anthropology, literature, and related fields. He was a prolific writer, many of whose works were not published until after his death.
The central concept of analytical psychology is individuation—the psychological process of integrating the opposites, including the conscious with the unconscious, while still maintaining their relative autonomy. Jung considered individuation to be the central process of human development.
Jung created some of the best known psychological concepts, including the archetype, the collective unconscious, the complex, and synchronicity. The Myers-Briggs Type Indicator (MBTI), a popular psychometric instrument, has been developed from Jung's theory of psychological types.
Though he was a practising clinician and considered himself to be a scientist, much of his life's work was spent exploring tangential areas such as Eastern and Western philosophy, alchemy, astrology, and sociology, as well as literature and the arts. Jung's interest in philosophy and the occult led many to view him as a mystic, although his ambition was to be seen as a man of science. His influence on popular psychology, the "psychologization of religion", spirituality and the New Age movement has been immense.
