During the first part of the study, eight tasks were taught to four participants with severe intellectual disability. A portable computer‐aided system was used that presented one pictorial instruction per task step, individually. During the second part of the study, the same computer‐aided system was used but the number of instruction occasions available for the tasks was reduced. In one condition, the system presented all the step instructions but mostly in small clusters rather than individually. In another condition, the system presented only some of the instructions. Data for the first part of the study showed that the participants managed to perform 83–97% of the task steps correctly. Data for the second part of the study showed that the condition in which instructions were clustered was more effective in maintaining high percentages of correct performance. Implications of the findings are discussed. Copyright © 1999 John Wiley & Sons, Ltd.
