In a one-to-one teaching situation, a discrete-trial involves presenting an antecedent (e.g., task materials and prompts provided by the trainer) for a target response (e.g., a child matching a printed word to the corresponding picture among several pictures) and presenting a consequence following the child’s response. A correct response is usually followed by a reinforcing consequence such as praise and or a preferred edible and an incorrect response, by a correction procedure. These trials are typically presented in rapid succession. I propose to compare two multiple-practice procedures following errors, static vs. varied antecedent, during discrete-trials teaching of 3-choice matching-to-sample discriminations with children with autism spectrum disorders. In both procedures, a child will receive praise and a preferred edible after each correct response and will be required to repeat the correct response five times after an error. In the static antecedent procedure, the task stimuli for all five repetitions will be identical to the training trial when the error occurred. The varied antecedent procedure, on the other hand, will involve altering some irrelevant features of the task stimuli across repetitions. Both procedures will be compared to a no-practice, differential reinforcement, baseline training procedure in a within-subject alternating-treatments design, replicated across three children. I expect that some learning will occur with each procedure, but children will perform best with the varied antecedent procedure, followed by the static antecedent procedure, and lastly, differential reinforcement. Findings of this study should help to improve the effectiveness of discrete-trials teaching.
