Although massed-trial instruction, distributed-trial instruction, and task interspersal have been shown to be effective methods of teaching skills to children with autism spectrum disorders, they have not been directly compared. In the current study, we taught 6 children to tact shapes of countries using these methods to determine which would result in the quickest acquisition. Five of the 6 participants acquired the targets in the massed-trial condition before the other 2 conditions.

We evaluated the effects of instructive feedback (IF) on the emergence of spoken category names with 2 children who had been diagnosed with autism. IF stimuli were presented during listener discrimination training and consisted of presenting the category name associated with each target stimulus. Results suggest that participants acquired the speaker relations in the absence of prompting and reinforcement. Clinical implications and future research on the use of IF as a teaching procedure for children with autism are discussed.

In 2 experiments, we examined the effects of programmed reinforcement for compliance with high-probability (high-p) instructions on compliance with low-probability (low-p) instructions. In Experiment 1, we compared the high-p sequence with and without programmed reinforcement (i.e., edible items) for compliance with high-p instructions. Results showed that the high-p sequence increased compliance with low-p instructions only when compliance with high-p instructions was followed by reinforcement. In Experiment 2, we examined the role of reinforcer quality by delivering a lower quality reinforcer (praise) for compliance with high-p instructions. Results of Experiment 2 showed that the high-p sequence with lower quality reinforcement did not improve compliance with low-p instructions; the addition of a higher quality reinforcer (i.e., edible items) contingent on compliance with high-p instructions did increase compliance with low-p instructions.
