Concept:The Skinner box is an experimental chamber designed by B.F. Skinner to study operant conditioning, where behavior is modified by reinforcement or punishment.Explanation:B.F. Skinner, a famous psychologist, created the Skinner box to observe how animals learn through consequences. In operant conditioning, behaviors that lead to positive outcomes are repeated, while those with negative outcomes are avoided. For example, a rat pressing a lever to get food is reinforced. Similarly, a child praised for homework learns to do it again, but scolding for breaking a plate reduces that behavior. This learning process is called operant or instrumental conditioning. The Skinner box is specifically used to study this type of learning, not verbal, motor, or incidental learning.Answer:B. operant conditioning
