Time Delay
Also called: progressive time delay, constant time delay, prompt delay
Definition
A prompt-fading method in which the prompt is given at the same moment as the natural cue at first, and then delayed by a growing interval (progressive) or a fixed interval (constant) so the learner has a chance to respond before the prompt arrives. Responding before the prompt shows stimulus control has transferred to the natural cue.
In plain language
At first the help comes right away. Then the helper waits a little longer each time before helping. When the learner answers before the help, the skill has transferred.
Example
"What is this?" — immediately "ball." Next session, a two-second wait before "ball." Later, four seconds, until the learner answers first.
Not time delay
Making the correct card larger and gradually shrinking it. That changes the materials, which is stimulus fading.
