Stimulus Fading

Also called: stimulus shaping, within-stimulus prompt fading

Definition

Gradually changing a physical feature of the teaching stimulus — size, color, position, intensity — that was added to make the correct response likely, until the stimulus is in its natural form. Stimulus shaping is the related method of gradually changing the shape of the stimulus itself.

Example

  • The correct picture starts out three times larger than the others and shrinks a little each session.

Not stimulus fading

  • Waiting a little longer before pointing to the correct picture. Delaying a response prompt is time delay.
