Which statement best distinguishes a stimulus prompt from a response prompt?

• A. Modifying the antecedent stimulus to evoke the correct response
• B. Providing a prompt to guide the learner's next movement
• C. Reinforcing the correct response
• D. Fading prompts over time

Answer: (A)

Stimulus prompts modify the antecedent stimulus to make the correct response more likely. This means changing the cue or setup the learner sees before they respond, so the right action is evoked without guiding the movement itself. The statement captures this directly by describing altering the antecedent stimulus to evoke the correct response. In contrast, a prompt that guides the learner’s next movement is a response prompt, which comes after the SD and directly shapes the movement or action. Reinforcing the correct response is about reinforcement, not prompting, and fading prompts over time is a general strategy for reducing prompts and can apply to either type, but it doesn’t define what makes a stimulus prompt different from a response prompt.
