History
Applied behavior analysis is the applied side of the experimental analysis of behavior. It is based on the principles of operant and respondent conditioning and represents a major approach to behavior modification and behavior management. Its origin can be traced back to Teodoro Ayllon and Jack Michael's 1959 article "The psychiatric nurse as a behavioral engineer" as well as to initial efforts to implement teaching machines.
The research basis of ABA can be found in the theoretical work of behaviorism and radical behaviorism originating with the work of B.F. Skinner. In 1968 Baer, Wolf and Risley wrote an article that was the source of contemporary applied behavior analysis providing the criteria to judge the adequacy of research and practice in applied behavior analysis. It became the core and centerpiece of behavior modification and behavioral engineering.
Work in respondent conditioning (what some would term classical conditioning) began with the work of Joseph Wolpe in the 1960s. It was improved by the work of Edna B Foa who did extensive research on exposure and response prevention for obsessive–compulsive disorder (OCD). In addition, she worked on exposure therapy for post-traumatic stress disorder.
Over the years most behavior analysts have existed and conducted research in many areas and University departments: behavior analysis, psychology, special education, regular education, speech–language pathology, communication disorders, school psychology, criminal justice and family life. They have belonged to many organizations including the American Psychological Association (APA) and have most often found a core intellectual home in the Association for Behavior Analysis International.

Famous quotes containing the word history:
“These anyway might think it was important
That human history should not be shortened.”
—Robert Frost (1874–1963)
“Boys forget what their country means by just reading “the land of the free” in history books. Then they get to be men, they forget even more. Liberty’s too precious a thing to be buried in books.”
—Sidney Buchman (1902–1975)
“History does nothing; it does not possess immense riches, it does not fight battles. It is men, real, living, who do all this.... It is not “history” which uses men as a means of achieving—as if it were an individual person—its own ends. History is nothing but the activity of men in pursuit of their ends.”
—Karl Marx (1818–1883)
