John G. Watson

John G. Watson was a renowned American psychologist best known for his pioneering work in behaviorism, emphasizing the study of observable behavior rather than internal thoughts or feelings. He believed that human actions are learned through interactions with the environment, primarily through conditioning. Watson significantly influenced psychology by promoting scientific methods and experimentation to understand behavior. His theories laid the groundwork for behavior therapy and shaped modern approaches to learning and development, making psychology more empirical and objective.
