An evaluation of the effects of the presence of low-preferred items on the resurgence of communicative responses in persons with developmental disabilities
MetadataShow full item record
The purpose of the current study was to evaluate the effects of the presence of low-preferred items during phase 3 on the resurgence of a previously taught communication response in persons with developmental disabilities and communication delays. To set up the phase 3 experimental condition, two phases occurred prior to the third phase, consistent with the resurgence paradigm (Epstein, 1983): (1) the reinforcement of communication target response 1 and (2) extinction of target response 1 and reinforcement of alternative response 2. During the third phase, all responses were extinguished across conditions, and conditions alternated every 2 min between (a) a condition where two low-preferred items were available and (b) no items were available. Results were discussed in terms of treatment relapse literature and some of the challenges facing both basic and applied researchers.
