| Summary: | The purpose of this study is to examine if Lag schedules can increase variability in children who use a selection-based communication system. For this study, two preschool aged children who use a selection-based communication were provided a binder with different mand frames. A multiple baseline design was used where all mand were reinforced in baseline sessions, followed by Lag 2 schedule condition to test if variation would emerge to meet the response requirements. Results of this study did not support the use of a Lag schedule to increase mand variability. Both participants failed to vary their responding and mand extinction was observed. Assent withdrawal and negative behaviors were also observed in both participants when the Lag schedule was put into effect. Limitations and possible future directions with practitioner-based research are discussed. |
