Comparison of simple and complex auditory-visual conditional discrimination training.

We investigated the relative effects of simple and complex auditory-visual discrimination training using an adapted alternating treatments design to establish derived stimulus relations in 2 children who had been diagnosed with autism and 1 typically developing peer. Emergence of untrained conditional relations was observed after training in both conditions, with a possible advantage of simple-sample training for 1 participant. Results of generalization and follow-up probes were mixed.
