Sigmund Freud is widely regarded as the father of psychoanalysis, a method of understanding the unconscious mind and its influence on behavior.

The id, according to Freud, is the unconscious part of the mind that contains basic drives and instincts.

The ego, according to Freud, is the conscious part of the mind that mediates between the id and the superego.

The superego, according to Freud, is the moral part of the mind that represents society's values and standards.

Free association is a technique used in psychoanalysis where the patient is encouraged to say whatever comes to mind, without censorship or judgment.

Dream analysis is a technique used in psychoanalysis where the therapist helps the patient to interpret the meaning of their dreams.

Transference is a process in psychoanalysis where the patient transfers feelings and attitudes from past relationships onto the therapist.

Carl Jung developed the theory of analytical psychology, which emphasizes the importance of the collective unconscious and archetypes.

The collective unconscious, according to Jung, is a reservoir of shared memories, symbols, and experiences that is common to all humans.

Archetypes are universal symbols and patterns that Jung believed are present in the collective unconscious and shape human experience.

Alfred Adler developed the theory of individual psychology, which emphasizes the importance of striving for superiority and overcoming feelings of inferiority.

The striving for superiority, according to Adler, is a basic human motive that drives us to achieve our goals and overcome obstacles.

Feelings of inferiority, according to Adler, are common to all humans and can motivate us to strive for superiority.

Compensation is a process of compensating for feelings of inferiority by developing exaggerated strengths in other areas.

Identification is a process of identifying with and imitating others in order to overcome feelings of inferiority.
