John Broadus Watson (January 9, 1878 – September 25, 1958) was an American psychologist who established the psychological school of behaviorism. Watson promoted a change in psychology through his address, Psychology as the Behaviorist Views it, which was given at Columbia University in 1913. Through his behaviorist approach, Watson conducted research on animal behavior, child rearing, and advertising. In addition, he conducted the controversial "Little Albert" experiment.
