Deficits in generating varied responding across repertoires is often observed in individuals with Autism Spectrum Disorders (ASD). Existing research explored the use of lag reinforcement schedule in promoting both verbal and non-verbal response variability in individuals with developmental disabilities. However, current research in this area is deemed minimal and with limitations. In this study, the effectiveness of an alternative lag reinforcement schedule, which incorporates both within response and between response lag criteria in promoting response variability was investigated with 5 participants in ASD using a block-building activity. The study also extended the investigation to a social game, I Spy game. Results of the study showed that the proposed lag reinforcement schedule was effective in promoting response variability in 2 participants in the block-building task. Furthermore, possible generalization effect of the intervention to promote varied responding in I Spy game was found in 1 of the participants. The study demonstrated that the proposed lag reinforcement schedule is feasible in promoting response variability in individuals with ASD, which hopefully can support future research in exploring possibilities to alleviate the problem of stereotyped responding.
