In the early 20th century, the field of psychology underwent significant transformation, particularly with the emergence of behaviorism. This approach emphasized the study of observable behaviors rather than internal mental processes. Pioneers like John B. Watson and B.F. Skinner argued that all behavior is learned through interactions with the environment. They conducted experiments demonstrating that behavior can be shaped and modified through reinforcement and punishment. This perspective guided many research strategies and influenced various domains, including education, therapy, and even animal training.
Despite its popularity, behaviorism faced criticism. Some psychologists argued that it overlooked cognitive processes that influence behavior. This led to the development of cognitive psychology, which seeks to understand internal mental states. Nevertheless, behaviorism laid the groundwork for practical applications in both educational and therapeutic settings.
