Prompting Condition Checklist		Scale
□ Least-to-Most Prompting	□ Most-to-Least Prompting	Strongly Disagree	Disagree	Neutral	Agree	Strongly Agree
1. When the child paid attention, the instructor gave the instruction, “Hit the ball,” and handed the bat to the child.		1	2	3	4	5
2. If the child responded incorrectly under the Least-to-Most Prompting condition, error correction was provided using three physical prompts, and no reinforcement was delivered.	2. If the child responded incorrectly under the Most-to-Least Prompting condition, error correction was provided using three physical prompts, and no reinforcement was delivered.	1	2	3	4	5
3. Under the Least-to-Most Prompting condition, if the child showed no response after a single instruction, a verbal prompt was provided after 2 seconds. If there was still no response after an additional 2 seconds, a modeling prompt was given. If there was still no response after another 2 seconds, a physical prompt was provided to complete the step.	3. Under the Most-to-Least Prompting condition, physical prompts were provided for the first two trials. In subsequent trials, if there was no response after 2 seconds, a modeling prompt was given. If the child produced two consecutive correct responses, prompting was faded to verbal prompts. If the child produced two consecutive incorrect responses, prompting reverted to physical prompts. (Verbal prompts were applied in the same manner as modeling prompts.)	1	2	3	4	5
4. Reinforcement was delivered for each correct response at every step, and additional reinforcement was provided upon completion of the entire task sequence.		1	2	3	4	5
5. The same procedure was repeated for a total of 10 trials.		1	2	3	4	5
6. Data on the child’s responses were collected consistently based on clearly defined operational definitions.		1	2	3	4	5
