Teams choose ABA prompt type by matching the help to the response, the person's access needs, the setting, and the likely path to independence. They may compare stimulus prompts, models, gestures, verbal cues, visual supports, or physical guidance. The choice should consider effectiveness, errors, effort, latency, intrusiveness, preference, safety, and ease of fading. No fixed hierarchy fits every skill or learner.
How teams choose ABA prompt type
Define the target, natural cue, response form, ordinary supports, likely errors, and current performance. Check vision, hearing, language, movement, pain, fatigue, sensory conditions, and AAC access. A prompt that the person cannot perceive or physically follow is an access mismatch.
Compare response and stimulus prompts
A response prompt acts on the response, such as a model, gesture, spoken hint, or physical guide. A stimulus prompt changes or highlights materials, such as size, position, color, contrast, or an added visual marker. Record the actual prompt instead of reporting only a broad level such as moderate help.
Use comparison research carefully
The prompting decision tool synthesizes comparative variables and recommends individualized selection and fading. In a small Lego-construction study, Libby and colleagues found different speed and error patterns across prompting arrangements and participants. That result illustrates variation rather than establishing a universal best sequence.
Set access and risk gates
The Ethics Code supports client involvement, competence, risk review, and data-based change. ASHA says AAC users should always have access to their tools or devices. Physical contact, blocked movement, removed communication, or a prompt that causes distress needs immediate review.
A practical example
June is learning to follow a picture recipe. Spoken hints are slow and difficult to process in a noisy kitchen. A visual highlight on the current recipe step produces five independent transitions across six opportunities, while verbal hints produce two across six. The clinician checks task order and exposure before selecting the visual approach.
Questions families can use
Which prompt options were accessible? What tradeoffs appeared in errors, speed, effort, and comfort? How comparable was exposure? Which ordinary support stays? What evidence will trigger fading or another strategy?
