Abstract
I investigated the effects of the stimulus-pairing observation procedure (SPOP) in conjunction with match-to-sample (MTS) training to establish untrained listener responses in three young children with autism spectrum disorder. I evaluated MTS training and the SPOP within a multiple-probe across-participants design. I conducted posttest probes across five-stimulus set after participants' exposure to MTS training and the SPOP to test for untrained listener responses. The participants demonstrated emergent untrained responses during the posttest probes and maintained untrained listener responses 3 weeks postmastery.
