Behavior AcquisitionDifficulty 3/5
In an errorless-learning program using progressive time delay, the RBT initially presents the SD and the prompt at the same time. After several correct trials, what should happen next?
- AIncrease the prompt to full physical guidance
- BWait for an error on each trial, then deliver the prompt as an error correction
- CStop prompting entirely and record every error the learner makes from that point on
- DInsert a short delay between the SD and the prompt
Show answer and rationale
Correct: D. Progressive time delay starts at 0-second delay (prompt with the SD) and gradually inserts a delay before the prompt. If the learner responds correctly before the prompt, stimulus control has transferred to the SD. Waiting for errors defeats the purpose of errorless teaching.
- C — Removing prompts abruptly produces errors and prompt-dependence data you cannot use.
- A — Increasing intrusiveness moves in the wrong direction after correct responding.
- B — Errorless learning is designed to prevent errors, not wait for them.
