In accordance with the American Psychologist, psychology is the academic study of the behavior and mind. The study of psychology spans a wide range of topics, including human development, activities, health, medicinal, sociality, and cognitive functions. The early 20th century saw psychoanalysis, which was created by Sigmund Freud (1856–1939), as the preeminent paradigm in psychology.
