Optimizing Dimensions of Reinforcement to Enhance Behavioral Interventions

This study examines how key parameters of reinforcement-specifically the timing and amount of rewards-affect learning, motivation, and performance in individuals with intellectual and developmental disabilities (IDD). The experimental design is informed by the Mathematical Principles of Reinforcement (MPR), a quantitative framework for understanding the relationship between reinforcement schedules and behavior.

Participants will complete tabletop tasks in a controlled setting. Tasks are designed to be simple and accessible, such as pressing a button or selecting a picture, and correct responses will earn small rewards. Across sessions, we will systematically vary reinforcement parameters, including inter-reinforcement interval and reinforcer magnitude, to evaluate their effects on response rate, accuracy, and persistence.

This is a Basic Experimental Studies with Humans (BESH) clinical trial, meaning the interventions are intended to understand fundamental behavioral processes, not to produce direct clinical benefit. The data will be analyzed using statistical models derived from MPR to identify which reinforcement dimensions are most effective in maintaining high rates of responding. The results may help refine behavior intervention strategies for individuals with IDD by providing an evidence-based understanding of how to optimize reinforcement delivery.
