A case study is presented that documents changes in eye contact duration following a program of sensory stimulation. Stimulation was provided by bouncing, being pulled on a scooter board, quick rocking, and use of an electric toothbrush. Data indicated that longer eye contact, decreased self-stimulation, and improved learning occurred. These results lend support to the hypothesis that some hyperactive children are underaroused and need stimulation. The rationale for treatment of these individuals is discussed.
