“…First described by Azrin (1972, 1973), PP OC involves the interruption of problem behavior followed by a period of physically guided practice of an appropriate alternative response. In addition, PP OC has been successful in treating a number of topographies of problem behavior, such as theft (Azrin & Wesolowski, 1974), floor sprawling (Azrin & Wesolowski, 1975), off-task behavior (Carey & Bucher, 1983), self-stimulatory behavior (Harris & Wolchik, 1979), self-injury (Conley & Wolery, 1980), and pica (Foxx & Martin, 1975).
