ABSTRACT
Lag schedules of reinforcement represent an increasingly researched strategy for addressing restricted and repetitive social communication of individuals with autism spectrum disorder (ASD). Although the body of literature suggests that lag schedules of reinforcement are generally effective for this purpose, studies have varied in their utilization of verbal rules describing the contingency. Furthermore, research has yet to evaluate generalized effects of lag schedules of reinforcement to social communication with peers. This study evaluated the implementation of a social skills curriculum, modified to incorporate lag schedules of reinforcement, on novel responding of participants with ASD. Participants attended training twice per week, with probes of novel responding collected with both researchers and non-participating peers. Results indicate that social skills training that incorporated lag schedules of reinforcement generally resulted in larger increases in novel responding than social skills training alone. Furthermore, effects of training generalized to novel responding to non-participant peers.
