Question 1
An RBT is teaching a learner to wash hands using a task-analyzed chain. After turning on the water, the learner immediately reaches for a paper towel, skipping the steps of wetting hands and applying soap. What should the RBT do?
▸Show the answer — and why each of the other three is wrong
B is correct.When teaching a behavior chain using a task analysis, skipping a step must be interrupted immediately to prevent the learner from practicing an improper sequence or accessing reinforcement for an incorrect chain. The technician provides the predetermined prompt for the correct next step. Allowing the learner to dry hands lets the learner practice an incorrect behavioral chain and contact inappropriate completion. Turning off the water and restarting from the beginning can turn chaining into an overly punitive procedure and does not teach correct step progression. Completing missed steps while the learner continues reinforces skipping required components.
