A Skinner Box is a controlled environment used in behavioral psychology to study animal behavior, particularly operant conditioning. It typically contains a lever or button that an animal, such as a rat or pigeon, can press to receive a reward, like food, or to avoid a punishment, like a mild electric shock. The box was developed by psychologist B.F. Skinner in the 1930s. By observing how animals learn to associate their actions with consequences, researchers can better understand the principles of reinforcement and behavior modification. This method has been influential in both psychology and education.
