Prompts and Prompt Fading

Personal E-mail Correspondence with Dr. Gina Green

Prompts and Prompt Fading(Green, 2008)
  • “A prompt is a supplemental antecedent stimulus that is used when a target stimulus does not yet reliably control a target response class.”
  • “Put another way, it's anything an interventionist does to get a response to occur when it does not yet occur consistently in the presence of the "intended" stimulus. “
  • “Prompt stimuli can take many forms: kinesthetic and tactile stimuli such as physical guidance or touch or vibrating pagers, modeled actions (live or videotaped), gestures, verbalizations (live or recorded), pictures and other symbols, text, etc. “

  • “Within-stimulus prompts are alterations of the physical properties or features of stimuli themselves that increase the likelihood that the target response will occur.
    • Examples of properties that might be altered include the volume of auditory stimuli,  and the shape, size, intensity, or color of visual stimuli (e.g., pictures, printed letters or numerals, text, video material). “ 
  • “Extra-stimulus prompts include everything else,
    • i.e., any type of prompt that does not involve altering the properties or features of stimuli directly.”

Prompts and Prompt Fading(Green, 2008)
  • “The big challenge with prompting is to use prompts enough to get target responses to occur frequently so they can be reinforced, but not so much that the responses occur only in the presence of the prompts.”  
  • “Based on my reading of the literature, including basic stimulus control research, when a response class is first being trained or is not yet at functional strength, interventionists should provide whatever assistance (in the form of prompts) is necessary to ensure high rates of correct (albeit prompted) responding and low rates of errors, then gradually remove (fade) the prompts as quickly as possible so as to transfer stimulus control from the prompt to the target stimulus.
  • That's errorless training, which I view as synonymous with most-to-least prompting.”

Prompts and Prompt Fading(Green, 2008)
  • “Prompts can be faded along any of several dimensions, depending on the nature of the prompts and the response class.
    • For example, physical prompts can be faded along the dimension of spatial location (graduated guidance);
    • some within-stimulus prompts can be faded along the dimension of intensity (intensity fading) or form (stimulus shaping, script fading);
    • and almost any type of prompt can be faded along the dimension of time (delayed cue).”
