Analytical Psychology owes its name and its methodology and theoretical basis to Swiss psychologist Carl Gustav Jung (1875–1961). Analytical psychology studies the unconscious mind, but, unlike psychoanalysis, analytical psychology sees the unconscious as not limited only to previously conscious content. Analytical psychology states that the unconscious possesses previously conscious concepts,  contents not yet capable of becoming conscious, and things that can not ever become fully conscious (archetypes of the collective unconscious). Apperception is one of the key concepts of analytical psychology, and it relates to psychic process through new contents are being assimilated into consciousness and made understandable and clear, based on their similarity to already existing contents in the consciousness. This process is mediated by conflicts between the two basic attitudes (introversion and extroversion) that direct the flow of psychic energy, and the conflict between the four basic functions consciousness has (thinking, feeling, sensation, and intuition).

Analytical psychology studies dreams, language, literature, religion and myth, and art to uncover collective unconcessness and its archetypes. The most basic archetypes are: the persona (a mask that the ego assumes and is socially accepted), the shadow (infantile and undeveloped aspects of the ego); the anima and animus (countersexual images that exist in men and women, respectively); and the Self (conscious personality and transpersonal basis of the ego). In analytical psychology, the therapeutic goal is "individuation", a process that induces self-conscious differentiation of egoconsciousness from different archetypes that an individual has constellated throughout its life. individual.
