Operant conditioning
Operant conditioning is a behavioral learning theory developed by B.F. Skinner, an American psychologist. This concept posits that behaviors are shaped and learned through the consequences they produce, which can be either reinforcing or punishing. Positive reinforcement strengthens a desired behavior by introducing a favorable stimulus, while negative reinforcement does so by removing an unfavorable stimulus. Conversely, punishment can also be positive, adding an undesirable stimulus to reduce a behavior, or negative, removing a pleasant stimulus to achieve the same goal.
Skinner famously conducted experiments using the Skinner box, where animals learned to perform specific actions to receive rewards or avoid punishments. The implications of operant conditioning extend beyond animal behavior; it has been applied in various domains, including education, therapy for psychological disorders, and behavior management in settings like workplaces and elder care. While operant conditioning has made a significant impact, it has also faced criticism for its limitations in addressing complex human behaviors and ethical concerns. Nonetheless, Skinner's work remains influential, demonstrating a lasting legacy in psychology and behavioral science.

Operant conditioning, a term coined by B. F. Skinner, American psychologist and radical behaviorist, is the idea that behavior is the learned result of consequences. Skinner, who introduced the concept in his 1938 book The Behavior of Organisms: An Experimental Analysis, theorized that operant conditioning in the form of reinforcements and punishments leads to an association between a behavior and its consequence. Positive reinforcement increases a desirable behavior by following it with a favorable stimulus. Negative reinforcement increases a desirable behavior by removing an unfavorable stimulus after the behavior is performed. Both positive and negative reinforcement seek to increase a desirable behavior. Punishment, like reinforcement, also has positive and negative varieties. Positive punishment is adding an unfavorable stimulus in an effort to eradicate an undesirable behavior. Negative punishment is removing an unpleasant stimulus to decrease undesirable behavior. Both positive and negative punishment seek to decrease an undesirable behavior.
Overview
Skinner designed an operant conditioning chamber, which came to be known as the Skinner box, to test his theory of operant conditioning on animals. The Skinner box prevented human interruption of the experimental session and allowed the experimenter to study the behavior of an animal as a continuous process. The box includes at least one lever or key that the animal can manipulate to release food, water, or some other reward or to avoid punishment such as an electric shock. Skinner’s experiments with rats and pigeons showed that the animals first hit the lever and released food accidentally; after a few accidental releases, the reinforcement of manipulating the lever ensured that the behavior would be repeated. Skinner believed that operant conditioning could be used in similar ways with human beings.
Modifying behavior through operant conditioning has been used in the treatment of phobias, obsessive-compulsive disorders, substance-abuse problems, and some sexual disorders, but the impact of Skinner’s theories about operant conditioning has proved to be immense, reaching far beyond the field of psychology. Zoos and other animal facilities routinely use food as a positive reinforcement to train animals to move within enclosed areas and to increase safety during veterinary examinations. With human subjects, operant conditioning has been used to control absenteeism in the workplace (such as when employers offer staff members with no absences a chance to win cash rewards), to increase sales (coupons), and to manage agitation in older adults with dementia. Perhaps no field has been more influenced by operant conditioning than education. Skinner’s assertion that positive reinforcement is more effective than punishment at changing and establishing desirable behavior led to the discrediting of punitive punishment in schools and the common application of timeouts (negative reinforcement) and a token economy (i.e., rewarding good behavior with gold stars that can be accumulated for prizes) instead.
Critics of operant conditioning have been vehement in pointing out its detriments. As early as 1959, American linguist and cognitive scientist Noam Chomsky argued that what worked in Skinner’s laboratory could be applied to complex human behavior only in a superficial way. In 1960 progressive educator A. S. Neil insisted that rewarding good behavior taught that the behavior was not worth doing for reasons other than the reward. Other critics were even more severe, charging that operant conditioning was dangerous and inhumane. Gradually, the influence of Skinner’s ideas declined, and by the twenty-first century, some declared that operant conditioning had become peripheral in psychology and related fields. However, in 2002 a list of ninety-nine top psychologists was published in the Review of General Psychology, and B. F. Skinner topped the list. Over the following years, operant conditioning continued to be used across a variety of disciplines.
