A stimulus prompt is a cue that makes the Sd for the target behavior more prominent.  For example, in order to encourage someone to push a button, you could make it big and a bright color.  Stimulus shaping is a changing of the physical dimensions of the stimulus over time.  For example, making the button to push smaller and more duller color over time.

Response prompts are verbal, modeling or physical guidance.  A prompt is a stimulus that assists the subject to evoke a correct response.  If the response is not correct, then it is not a prompt.

A generic response prompt is a cue with a general item such as a string around your finger that leads you to engage in some specific target behavior.
