B.F. Skinner was an American psychologist known for his work in behaviorism, a field that studies how people and animals learn through interactions with their environment. He developed the concept of operant conditioning, which explains how behaviors can be shaped by rewards and punishments. Skinner believed that understanding these principles could help improve education and behavior management. Skinner is famous for his invention of the Skinner box, a device used to study animal behavior. In these boxes, animals like rats or pigeons could be rewarded with food for pressing a lever, demonstrating how reinforcement influences actions. His research has had a lasting impact on psychology and education.
