Shaping earlier responses typically changes which approximation produces the programmed reinforcer after the learner reliably meets the current criterion. The plan should identify the transition clearly and avoid sudden, unexplained loss of an expected outcome. Earlier responses still need accurate acknowledgment, and communication, relationships, play, basic needs, safety, and ordinary access should remain available. Distress or loss of participation calls for review.
Explain how shaping earlier responses will be handled
State the old criterion, new criterion, signal for the change, consequence for each response range, and rollback rule. The learner may need a brief transition, model, visual explanation, or denser opportunity schedule. An earlier approximation should not be mislabeled as misconduct.
Separate the programmed reinforcer from ordinary life
Identify what is contingent and what remains freely available. Do not make food needed for health, water, bathroom access, communication, mobility, prescribed care, relationships, rest, or emergency help depend on meeting the new approximation. Client-selected leisure also needs reasonable free access.
Understand the behavioral mechanism
The ABAI principles page and BACB outline describe shaping through differential reinforcement of successive approximations. A gradual-change review distinguishes changing a response requirement from fading a stimulus or thinning a schedule. These conceptual sources do not set an acceptable frustration level.
Respond to withdrawal
The Ethics Code addresses positive reinforcement, client involvement, consent and assent when applicable, risk, and evaluation. Keep an accessible stop or change message available. If participation or wellbeing declines, pause and review the criterion, outcome, pacing, and goal.
A practical example
Zoe is practicing basketball shots for a chosen recreation goal. After close-range shots become stable, the next criterion moves one floor marker back. Coaching praise and ordinary play continue for all attempts; the special score token follows the current marker. Zoe can choose the earlier line or end practice.
Questions families can use
What changes at the criterion shift? How is the learner told? Which outcomes stay freely available? What happens after an earlier approximation? Which sign triggers rollback or a new plan?
