Which influential early 20th-century scientific theory revolutionized the understanding of psychology? 🔊
The early 20th-century scientific theory that revolutionized psychology was Sigmund Freud's psychoanalysis. Freud introduced concepts such as the unconscious mind, defense mechanisms, and the significance of early childhood experiences in shaping personality and behavior. His theories emphasized the impact of unresolved conflicts and repressed emotions on mental health, pioneering new therapeutic techniques that focused on talk therapy and exploring patients' thoughts and feelings. Psychoanalysis laid the foundation for modern psychotherapy and influenced various fields, including literature, art, and cultural studies, by prompting a re-evaluation of human behavior and motivations, leading to broader developments in psychological theory.
