The Psychology of John B. Watson: Understanding the Father of Behaviorism


The field of psychology has been shaped by many great minds, but few have had as significant an impact as John B. Watson. Known as the father of behaviorism, Watson was a pioneer in the study of human behavior and psychology.

Who was John B. Watson?

John Broadus Watson was born on January 9, 1878, in the small town of Travelers Rest, South Carolina. He grew up in a poor family, but despite his humble beginnings, he went on to become one of the most influential psychologists of the 20th century.

Watson received his Ph.D. in psychology from the University of Chicago in 1903, where he worked alongside the likes of James Angell and John Dewey. After completing his degree, Watson went on to teach at several universities, including Johns Hopkins University, where he developed his theory of behaviorism.

What is Behaviorism?

Behaviorism is a school of psychology that emphasizes the study of observable behavior, rather than internal mental processes or subjective experiences. According to behaviorists, behavior is shaped by environmental factors, such as reinforcement and punishment, rather than innate abilities or unconscious desires.

Watson was a strong proponent of behaviorism, and his work helped to establish it as a dominant force in the field of psychology. His famous quote, "give me a dozen healthy infants, well-formed, and my own specified world to bring them up in and I’ll guarantee to take any one at random and train him to become any type of specialist I might select—doctor, lawyer, artist, merchant-chief and, yes, even beggar-man and thief," illustrated his belief that behavior could be shaped by environmental factors.

Watson’s Famous Experiment: Little Albert

One of Watson’s most famous experiments was the "Little Albert" experiment, in which he conditioned a young child to be afraid of a white rat. Watson and his assistant, Rosalie Rayner, presented the rat to the child and then made a loud noise whenever he reached for it. After several repetitions, the child began to associate the rat with the loud noise and became afraid of it.

Watson used this experiment to support his theory of behaviorism, showing that fear could be conditioned in a child through environmental factors. The ethics of this experiment have been called into question, but its impact on the field of psychology cannot be denied.

Watson’s Influence on Modern Psychology

Although behaviorism has fallen out of favor in recent years, Watson’s influence on the field of psychology cannot be overstated. His work helped to bridge the gap between psychology and other fields, such as physiology and neuroscience.

Watson’s ideas also had a significant impact on the field of advertising and marketing. His theories of behaviorism were used to create ads and commercials that appealed to consumers’ desires and fears. Even today, many marketing techniques are based on Watson’s principles.


John B. Watson was one of the most influential psychologists of the 20th century, and his theory of behaviorism had a profound impact on the field of psychology. Although his theories have been criticized in recent years, his work helped to establish psychology as a legitimate scientific field and paved the way for modern psychology as we know it today.
