Radical behaviorism
Résumé
Radical behaviorism is a "philosophy of the science of behavior" developed by B. F. Skinner. It refers to the philosophy behind behavior analysis, and is to be distinguished from methodological behaviorism—which has an intense emphasis on observable behaviors—by its inclusion of thinking, feeling, and other private events in the analysis of human and animal psychology. The research in behavior analysis is called the experimental analysis of behavior and the application of the field is called applied behavior analysis (ABA), which was originally termed "behavior modification."
Radical behaviorism inherits from behaviorism the position that the science of behavior is a natural science, a belief that animal behavior can be studied profitably and compared with human behavior, a strong emphasis on the environment as cause of behavior, and an emphasis on the operations involved in the modification of behavior. Radical behaviorism does not claim that organisms are tabula rasa whose behavior is unaffected by biological or genetic endowment. Rather, it asserts that experiential factors play a major role in determining the behavior of many complex organisms, and that the study of these matters is a major field of research in its own right.
Operant conditioning
Skinner believed that classical conditioning did not account for the behavior that many people are interested in, such as riding a bike or writing a book. His observations led him to propose a theory about how these and similar behaviors, called "operants", come about.
Roughly speaking, in operant conditioning, an operant is actively emitted and produces changes in the world (i.e., produces consequences) that alter the likelihood that the behavior will occur again.
As represented in the table below, operant conditioning involves two basic actions (increasing or decreasing the probability that a specific behavior will occur in the future), which are accomplished by adding or removing stimuli.
In other words:
If the probability of a behavior is increased as a consequence of the presentation of a stimulus, that stimulus is a positive reinforcer.
