Behavior Analysis and Therapy
The purpose of the current study was to look at waiting behavior and how it is acquired among children with disabilities. Within this study a multi-experimental design was used to compare the effectiveness of two interventions, a signaled intervention using a visual timer and an unsignaled intervention. Both interventions were implemented across one changing criterion design that allowed for a progressive time delay to increase behavior. This experiment was also conducted across 4 participants to assess the intervention effects across multiple participants. The results showed that the signaled intervention was more effective in increasing the waiting behavior across all four participants. Three participants did see an increase in waiting behavior across the unsignaled intervention phases, although data indicates those results were not as clinically significant or consistent as the signaled intervention.
