Prompt cues for recording in self-monitoring interventions can be delivered through a number of different modalities. The current study evaluated a self-monitoring intervention using a discreet auditory prompt (via a single wireless in-ear headphone) plus reinforcement for recording accuracy on increasing on-task behaviors in individuals with autism spectrum disorders. Two of the three individuals demonstrated an increase in on-task behaviors and accuracy of recording during the initial intervention phase, and the third participant required an additional reinforcement contingency for on-task behavior. Increases in on-task behavior did not generalize to a general education setting for any of the participants.
