Study Summary

This trial is studying how reinforcement histories relate to the prevalence of extinction bursts in people with intellectual and developmental disabilities.

Who is the study for?
This trial is for adults over 18 with intellectual and developmental disabilities (IDD) who can interact with study materials and agree to participate. It's not for those under 18, without disabilities, or unable to use the study items.Check my eligibility
What is being tested?
The study examines how past reinforcement affects 'extinction bursts'—increases in challenging behavior when trying to stop it—in adults with IDD. The goal is to improve interventions by understanding these reactions better.See study design
What are the potential side effects?
Since this research focuses on behavioral analysis rather than medical intervention, traditional physical side effects are not a concern; however, participants may experience increased challenging behaviors temporarily.

4Treatment groups
Experimental Treatment
Group I: "Expensive" Unit Price, Establishing OperationExperimental Treatment1 Intervention
Pre-extinction baseline unit price for the programmed reinforcer will be its Pmax, plus one half of the distance between its Pmax and its breakpoint. Extinction will be introduced at the beginning of the relevant appointment, before within-appointment reinforcer consumption has had an opportunity to approximate demand.
Group II: "Expensive" Unit Price, Abolishing OperationExperimental Treatment1 Intervention
Pre-extinction baseline unit price for the programmed reinforcer will be its Pmax, plus one half of the distance between its Pmax and its breakpoint. Extinction will be introduced at the end of the relevant appointment, after within-appointment reinforcer consumption has approximated demand.
Group III: "Cheap" Unit Price, Establishing OperationExperimental Treatment1 Intervention
Pre-extinction baseline unit price for the programmed reinforcer will be its Pmax, minus one half of the distance between its Pmax and its breakpoint. Extinction will be introduced at the beginning of the relevant appointment, before within-appointment reinforcer consumption has had an opportunity to approximate demand.
Group IV: "Cheap" Unit Price, Abolishing OperationExperimental Treatment1 Intervention
Pre-extinction baseline unit price for the programmed reinforcer will be its Pmax, minus one half of the distance between its Pmax and its breakpoint. Extinction will be introduced at the end of the relevant appointment, after within-appointment reinforcer consumption has approximated demand.
