Decreasing self-stimulatory behavior with physical exercise in a group of autistic boys

Five autistic boys were observed during 27 language training sessions. Each session followed one of three periods: physical exercise, TV watching, or regular academic work. It was found that the lowest levels of self-stimulation followed physical exercise, there were no differences in the levels of self-stimulation following TV watching and following academics, and the levels of correct question answering were not affected by the three different previous periods.
