Experimental analysis of behavior in the context of Learning theory (education)

Burrhus Frederic Skinner (March 20, 1904 – August 18, 1990) was an American psychologist, behaviorist, inventor, and social philosopher. He was the Edgar Pierce Professor of Psychology at Harvard University from 1948 until his retirement in 1974.

Skinner developed behavior analysis, especially the philosophy of radical behaviorism, and founded the experimental analysis of behavior, a school of experimental research psychology. He also used operant conditioning to strengthen behavior, considering the rate of response to be the most effective measure of response strength. To study operant conditioning, he invented the operant conditioning chamber (aka the Skinner box), and to measure rate he invented the cumulative recorder. Using these tools, he and Charles Ferster produced Skinner's most influential experimental work, outlined in their 1957 book Schedules of Reinforcement.

Applied behavior analysis (ABA), also referred to as behavioral engineering, is a psychological discipline that uses respondent and operant conditioning to change human and animal behavior. ABA is the applied form of behavior analysis; the other two are: radical behaviorism (or the philosophy of the science) and experimental analysis of behavior, which focuses on basic experimental research.

The term applied behavior analysis has replaced behavior modification because the latter approach suggested changing behavior without clarifying the relevant behavior-environment interactions. In contrast, ABA changes behavior by first assessing the functional relationship between a targeted behavior and the environment, a process known as a functional behavior assessment. Further, the approach seeks to develop socially acceptable alternatives for maladaptive behaviors, often through implementing differential reinforcement contingencies.

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."
