There is limited research pertaining to the effects of exercise on the behavior of children with autism. Previous researchers focused on exploring the dimensions of the exercise itself, leaving a functional account of the effects of exercise undetermined. There is recent evidence that exercise suppresses responses maintained by automatic reinforcement. The purpose of the present study was to better identify the relevant independent variable in such research and to assess if there were differential effects of exercise across functional response classes. The experimenter conducted a trial-based functional analysis and then implemented a sedentary or vigorous activity on alternating days to determine the impact of exercise on engagement, stereotypy, and challenging behavior. Results across functional response classes were variable as were data across individual sessions. There was a mean suppression of behavior maintained by nonsocial reinforcement during post-sedentary (4.3%) and post-exercise sessions (2.3%). A discussion of the role of matched stimulation and heart rate as a pertinent variable follows.
