In 1920, psychologists at Johns Hopkins University conducted one of the most famous and controversial experiments in the history of psychology.The study, now known as the Little Albert experiment, was designed to test whether fear could be learned through conditioning. Led by behaviorist psychologist John B. Watson and his assistant Rosalie Rayner, the experiment involved a nine-month-old infant who was exposed to a white rat while a loud noise was used to create a fear response.Over time, the child began to fear not only the rat but other soft and furry objects as well.In this episode of The Strange History Podcast, we explore the origins of behaviorism, the unusual experiment that shaped modern psychology, and the ethical questions that followed.
