We assessed the effects of automatically delivered favorite stimulation on engagement and indices of happiness of two adults with multiple disabilities during their use of a stationary bicycle. The participants typically received four 5-min. sessions per day over a period of about 3.5 mo. Analysis showed that one participant had a significant increase in both those measures while the other participant had a significant increase in engagement during the intervention phases of the study (when the stimulation was present) as opposed to the baseline periods (when the stimulation did not occur). Implications of the findings are discussed.
