The individual often regarded as the "father of modern psychology" is Sigmund Freud. Freud's pioneering work introduced the concepts of the unconscious mind, psychoanalysis, and the significance of dreams in understanding human behavior. His theories argued that early childhood experiences shape personality and can lead to psychological conflicts. Freud developed techniques such as free association and dream interpretation to uncover repressed memories. While some of his ideas have faced criticism, Freud's impact on psychology laid the groundwork for future developments in mental health treatment and understanding of human motivation.
