The Vienna School of Psychology refers to a group of psychologists and theorists based in Vienna during the late 19th and early 20th centuries. This school is primarily associated with the work of Sigmund Freud, who developed psychoanalysis, a method for treating mental illness and understanding human behavior through the exploration of the unconscious mind. In addition to Freud, the Vienna School included influential figures like Alfred Adler and Carl Jung, who contributed to the development of individual psychology and analytical psychology, respectively. The ideas from this school laid the groundwork for various psychological theories and practices that continue to influence modern psychology today.
