A teaching procedure by which a specific sequence of responses is taught such that the completion of the previous response serves as the SD for the next response.

• A. Incidental Teaching
• B. Discriminative Stimulus (SD)
• C. Error correction
• D. Prompt

Answer: (A)

Sequencing a chain of responses where the completion of one response serves as the cue for the next is a hallmark of how chaining works in naturalistic teaching. Incidental teaching uses the learner’s ongoing behavior in a real-life context to create opportunities to extend skills, often by allowing each completed step to set up the next step. In this approach, the end of one response naturally becomes the signal (the SD) that the next response is appropriate, guiding the learner through a specific sequence with reinforcement coming from the environment rather than from artificial prompts. This natural, learner-driven progression through a chain is what aligns best with the description.

Other options focus more on distinct mechanisms: a discriminative stimulus signals that reinforcement is available but isn’t about building a linked sequence of steps; a prompt is an external cue to elicit a response rather than a natural chain arising from prior completions; and error correction focuses on correcting mistakes rather than shaping a forward sequence of behaviors.
