This study was aimed at assessing a new computer‐based system to promote task performance in three adults with severe developmental disabilities. The new system, which was small and battery powered, could provide auditory and vibratory prompts in addition to pictorial instructions concerning the task steps. To control for the effects of the computer‐based system, the subjects were also exposed to a card system. The results showed that the subjects had a significantly higher level of correct performance on the tasks presented with the computer‐based system than on the tasks presented with the card system. Two of the subjects, moreover, seemed to prefer the computer‐based system to the card system. © 1998 John Wiley & Sons, Ltd.
