The behaviorist school of thought is a psychological perspective that focuses on observable behaviors rather than internal mental processes. It emphasizes the idea that all behaviors are learned through interactions with the environment, primarily through conditioning. Key figures in this field include B.F. Skinner and John B. Watson, who believed that behavior can be shaped and modified through reinforcement and punishment. Behaviorism rejects the notion of introspection and subjective experiences, arguing that psychology should be a science based on measurable and observable phenomena. This approach has influenced various fields, including education and therapy, by promoting techniques such as operant conditioning and classical conditioning to modify behavior.
