This study examined the effects of self-monitoring on the on-task behavior of three six to nine-year-old boys with autism spectrum disorder. The study also looked into the individuals' ability to accurately self-monitor their behavior. The participants were taught to self-monitor their behavior using a MotivAider™ that was set to vibrate on one-minute fixed intervals. The vibration acted as a tactile cue to prompt the participant to ask themselves “Am I on task?” A concurrent multiple baseline design with an embedded changing criterion design was utilized. Results showed on-task behavior significantly increased while accuracy of self-monitoring increased gradually once the intervention was implemented.
