 MODULE: Time Delay


Time delay is an evidence-based practice that can be used to teach learners with ASD a variety of skills including those related to language/communication, academic, and social/play. With time delay, team members implement learning trials in which a cue and controlling prompt are used to teach target skills. As learners become more successful at using newly acquired skills, team members increase the time interval between the initial cue and the controlling prompt by using one of two procedures: constant time delay and progressive time delay. With constant time delay, a fixed delay interval of three to five seconds is used. With progressive time delay, team members gradually increase the delay between the initial cue and the controlling prompt using 1-second intervals. With both procedures, the goal is to fade the time delay so that learners begin to independently use target skills. Time delay can be implemented within a variety of activities at home or across the school day including small group and individual work times. Additionally, team members can address issues related to generalization of skills by embedding time delay procedures within ongoing routines and activities and by training typically developing peers to use time delay during learning activities.
