Discover the origins of psychology with Hank Green. Explore historical theories, from Freud to behaviorism, and learn how we study the human mind.
In the premiere episode of Crash Course Psychology, host Hank Green introduces viewers to the most complex piece of the universe we currently know about: the human mind. This foundational episode explores the history and evolution of psychology, which translates from Latin as "the study of the soul" but is formally defined today as the science of behavior and mental processes. Green traces the discipline's roots from ancient thinkers like Aristotle, who incorrectly believed consciousness resided in the heart, to the first psychological exams in ancient China and early psychiatric wards in the 800s.
The video provides a comprehensive overview of the major schools of thought that have shaped the field. You'll learn about Wilhelm Wundt, who established the first psychology lab in 1879, and the rise and fall of structuralism. The episode then contrasts this with William James's functionalism, which focused on the evolutionary purpose of our behaviors. Naturally, the episode dedicates significant time to the monumental, albeit controversial, impact of Sigmund Freud and his revolutionary theory of psychoanalysis, which proposed that unconscious motives and repressed memories shape our personalities.
Finally, the episode transitions into the 20th century, introducing behaviorists like Ivan Pavlov, John B. Watson, and B.F. Skinner, who shifted the focus entirely to observable behaviors rather than internal feelings. By weaving together these diverse and sometimes conflicting perspectives—from psychodynamic theories to humanism and neuroscience—Green brilliantly illustrates that modern psychology is an integrative melting pot. This first lesson sets the stage for an exciting series, proving that there is no single way to crack open the human mind; it must be approached from all sides.
