Progressive Time Delay

Progressive time delay is a means of systematically providing and fading the use of prompts. Initially, an individual is prompted when the cue is presented (zero-second delay), then the time between the cue and the prompt is increased (e.g., beginning with a one-second delay and increasing to a two-second delay). In this video, a teacher uses progressive time delay to help Emory learn sight words. The teacher provides verbal reinforcers throughout the task and a tangible reinforcer at the end of the task.
