Excerpt: "Behavior modification is "learning with a particular intent, namely clinical treatment and change" (Ullmann & Krasner, 1965, p. 1). Initially behavior modification referred largely to operant techniques and behavior therapy to respondent techniques. As early as 1965 the terms behavior modification and behavior therapy were used interchangeably (O'Donohue & Krasner, 1995). With publication of the journal Behavior Research and Therapy in 1963 and the founding of the Association for the Advancement of Behavior Therapy, behavior therapy became a general term for all of these techniques. Thus behavior therapy will be used in this discussion."
