Lag Schedules

Five participants with autism spectrum disorder (ASD) between the ages of 10 and 14 years attended a twice-weekly social skills group for 8 weeks. A multiple probe design across skills with concurrent replication across participants was utilized to assess the effects of social skills training using multiple exemplars and lag schedules on social skill variability. Prior to intervention, participants demonstrated low levels of skill accuracy and appropriate variability. Training with one and three exemplars of target skills without lag schedules resulted in no to small increases in appropriate variability, despite increases in skill accuracy. Following introduction of lag schedules, substantial increases were observed. Post-intervention rating scales completed by parents of participants indicated improvements in social functioning and reductions in repetitive behavior.

Lag Schedules

We evaluated the effects of lag schedules of reinforcement and functional communication training (FCT) on mand variability and problem behavior in two children with autism spectrum disorder. Specifically, we implemented FCT with increasing lag schedules and compared its effects on problem behavior with baseline conditions. The results showed that both participants exhibited low rates of problem behavior during treatment relative to baseline during and following schedule thinning (up to a Lag 5 schedule arrangement). Variable and total mands remained high during schedule thinning. With one participant, variable manding persisted when the value of the lag schedule was reduced to zero. The current results are discussed in terms of implications for training multiple mand topographies during FCT for the potential prevention and/or mitigation of clinical relapse during challenges to treatment.
