Radical behaviorism

Radical behaviorism, or the conceptual analysis of behavior, was pioneered by B. F. Skinner and is his "philosophy of the science of behavior." It refers to the school of psychology known as behavior analysis, and is distinguished from methodological behaviorism—which has an intense emphasis on observable behaviors—by its inclusion of thoughts, emotions, and other internal mental activity in the analysis and theorizing of human and animal psychology. The research in radical behaviorism is called the experimental analysis of behavior and the application of this field is called applied behavior analysis (ABA).
