Effects of a Perseverative Interest-Based Token Economy on Challenging and On-Task Behavior in a Child with Autism

We compared the effects of a token economy intervention that either did or did not include the perseverative interests of a 7-year-old boy with autism. An alternating treatment design revealed that the perseverative interest-based tokens were more effective at decreasing challenging behavior and increasing on-task behavior than tokens absent the perseverative interest during an early literacy activity. The beneficial effects were then replicated in the child's classroom. The results suggest that perseverative interest-based tokens might enhance the effectiveness of interventions based on token economies.
