Behavior and Behavior Mechanisms
Rapp (2007), suggested that, when treating automatically-reinforced behavior using competing stimuli, whether a stimulus is matched or unmatched is a predictor of whether an AO (for matched stimuli) or EO (for unmatched stimuli) effect will be obtained following response competition. Two young males, with an autism spectrum disorder, who engaged in high levels of stereotypic behavior maintained by automatically reinforcement participated. The effects of competing stimuli on levels of stereotypy were assessed using a three-component multiple schedule (i.e., BL - access to stimuli - BL). During the assessment, the competing item was either a matched or unmatched stimulus identified using a competing items assessment (Piazza et al., 1998; Piazza, Adelinis, Hanley, Goh, &Delia, 2000. For both participants, providing access to the matched stimuli suggested no clear pattern of either establishing or abolishing effect. However, for unmatched stimuli the results suggested a clear pattern of a potential abolishing effect for both participants.
