Sigmund Freud

The correct answer is Option (3) - Sigmund Freud

Sigmund Freud, an Austrian neurologist, is widely regarded as the founder of the field of psychoanalysis.

Sigmund Freud (1856–1939) was a pioneering figure in the field of psychology, particularly known for his development of psychoanalysis. He studied medicine at the University of Vienna and later specialized in neurology. Freud's observations and clinical work with patients suffering from various mental disorders led him to formulate revolutionary theories about the human mind and behavior. Freud developed the theory and practice of psychoanalysis, which became a significant school of thought in psychology. Psychoanalysis focuses on exploring the unconscious mind and its influence on human behavior, emotions, and personality development. Freud proposed that unconscious conflicts, desires, and childhood experiences shape an individual's thoughts, feelings, and actions.

Freud also developed psychoanalytic therapy as a method for treating mental disorders. This therapy involves exploring unconscious conflicts and experiences through techniques such as free association, dream analysis, and interpretation of slips of the tongue (Freudian slips). Despite criticisms and revisions to some of his ideas, Freud's contributions to psychology, psychiatry, and psychotherapy have had a profound and lasting impact. Psychoanalysis has influenced various fields, including clinical psychology, psychiatry, literature, art, and popular culture.

Overall, Sigmund Freud's pioneering work laid the foundation for modern psychoanalytic theory and practice, shaping our understanding of human psychology and behavior. He remains one of the most influential figures in the history of psychology.
