“…Future research should examine variables that may influence preference for and performance under different reinforcer arrangements. To date, researchers have investigated the effects of the type of reinforcer (food vs. activity reinforcers, e.g., DeLeon et al., 2014), the magnitude of reinforcement (e.g., Ward‐Horner, Pittenger, et al., 2017), the quality of reinforcement (e.g., Ward‐Horner, Muehlberger, et al., 2017), and the type of task (mastered vs. unmastered tasks, e.g., Frank‐Crawford et al., 2019). More recently, function of problem behavior, specifically escape‐maintained problem behavior, has also been explored (e.g., Frank‐Crawford et al., 2021; Fulton et al., 2020; Robinson & St. Peter, 2019).…”
