“…During FCT, a functional communication response (FCR) produces access to the reinforcer for destructive behavior based on the results of a functional analysis (i.e., functional reinforcement), and destructive behavior is placed on extinction. Although FCT typically reduces destructive behavior by more than 95% postreinforcement-schedule thinning (e.g., Greer, Fisher, Saini, Owen, & Jones, 2016), treatment relapse in the form of resurgence often occurs during the thinning process (Briggs, Fisher, Greer, & Kimball, 2018).
