A "behaviorist" is a psychologist who studies behavior, focusing on observable actions rather than internal thoughts or feelings. This approach emphasizes the idea that all behaviors are learned through interactions with the environment, often through processes like classical conditioning and operant conditioning. Behaviorists believe that by understanding the principles of learning, we can predict and control behavior. Key figures in this field include B.F. Skinner, known for his work on reinforcement, and John B. Watson, who is often considered the founder of behaviorism. Their research has influenced various areas, including education and therapy.
