Functional Communication Training Without Extinction Using Concurrent Schedules of Differing Magnitudes of Reinforcement in Classrooms

Abstract

This study investigated the effects of functional communication training (FCT) implemented with concurrent schedules of differing magnitudes of reinforcement in lieu of extinction to reduce inappropriate behaviors and increase alternative mands. Participants were four adolescent students diagnosed with severe emotional and behavior disorders (SEBD), and mild to severe intellectual disabilities. Functional analyses revealed inappropriate behaviors as escape maintained. During subsequent FCT, the reinforcement provided for inappropriate behaviors was escape from task for 30 s (S^R−). The reinforcement for the alternative mand was a 30-s escape from task during which access to a preferred activity was provided (S^R−/PA). Results for three of the participants who had mild to moderate intellectual disabilities were highly successful. Time on task and generalization data also were recorded for two of the participants All sessions were implemented in the participants’ natural classrooms by their classroom teachers, without the adverse side effects of extinction.
