Abstract

We evaluated the effects of operant discrimination training (ODT) on the vocalizations of 3 boys with autism. We compared ODT to a stimulus–stimulus pairing (SSP) condition and a control condition in an adapted alternating-treatments design. ODT increased the target vocalizations of all participants compared to the control condition, and its effects were similar to SSP. All participants preferred ODT to SSP.
