A comparison of synchronous and noncontingent stimulus delivery on task engagement

Abstract

AbstractSynchronous schedules of reinforcement are those in which the onset and offset of a reinforcer are synchronized with the onset and offset of a target behavior. The current study replicated and extended Diaz de Villegas et al. (2020) by comparing synchronous reinforcement to noncontingent stimulus delivery while evaluating on‐task behavior of school‐age children. A concurrent‐chains preference assessment was then used to determine the preferred schedule. Results indicated that the synchronous schedule was more effective than the continuous, noncontingent delivery of the stimulus at increasing on‐task behavior but that the children preferred noncontingent delivery. Additionally, the use of synchronous and noncontingent delivery did not alter the children's preference for the task.
