Implementation of a token economy by peer tutors to increase on-task physical activity time of autistic children.

The data generated in this study were graphed for visual inspection of the raw data and means. Of the 5 subjects, 4 improved their time on task on the balance beam in at least one of the intervention phases. The other subject did not improve during the intervention phases but, there was a positive slope in the final intervention phase which might have continued had the intervention been longer. Further study is required.
