title: Influence of motivating operations and discriminative stimuli on challenging behavior maintained by positive reinforcement.
abstract: We examined the effects of an establishing operation (EO) and abolishing operation (AO) on stimulus control of challenging behavior. Two participants with developmental disabilities and challenging behavior participated. In Phase I, a functional analysis was conducted to identify the consequences maintaining challenging behavior. In Phase II, a discrimination between SD and SΔ was trained. In Phase III, pre-session MOs (i.e., EO and AO conditions) were arranged to assess their effects on challenging behavior. Finally in Phase IV, in addition to manipulating pre-session MOs the challenging behavior was evaluated under extinction in both SD and SΔ conditions. Results indicated that in the context of extinction when pre-session EO and AO conditions were manipulated, responding not only became differentiated but was higher in both SD and SΔ conditions in the pre-session EO condition when compared to the pre-session AO condition.
