Operant conditioning (also called instrumental conditioning) is a learning process through which the strength of a behavior is modified by reinforcement or punishment. It is also a procedure that is used to bring about such learning.Modern marksmanship training is such an excellent example of behaviorism that it has been used for years in the introductory psychology course taught to all cadets at the US Military Academy at West Point as a classic example of operant conditioning. In the 1980s, during a visit to West Point, B.F. Skinner identified modern military marksmanship training as a near-perfect application of operant conditioning.It is entirely possible that no one intentionally sat down to use operant conditioning or behavior modification techniques to train soldiers in this area…But from the standpoint of a psychologist who is also a historian and a career soldier, it has become increasingly obvious to me that this is exactly what has been achieved. Operant conditioning (also called instrumental conditioning) is a learning process through which the strength of a behavior is modified by reinforcement or punishment. It is also a procedure that is used to bring about such learning. Although operant and classical conditioning both involve behaviors controlled by environmental stimuli, they differ in nature. In operant conditioning, stimuli present when a behavior is rewarded or punished come to control that behavior. For example, a child may learn to open a box to get the sweets inside, or learn to avoid touching a hot stove; in operant terms, the box and the stove are 'discriminative stimuli'. Operant behavior is said to be 'voluntary': for example, the child may face a choice between opening the box and petting a puppy.
