“…The first study (Lancioni et al, 1998) had two main goals: (a) comparing the effectiveness of the VICAID system with that of a conventional card system for establishing task performance in three participants with severe developmental disabilities and (b) checking the participants' preference between the two systems. The first version of the VICAID system (with a palmtop computer with a black and white screen) was used.…”

The development of technologies to assist people with severe and profound developmental disabilities to engage in constructive activity without constant support from carers may assist such persons to participate fully in vocational and other occupational activities. We describe the development, evaluation and use of VICAID, a system based on a radically simplified palmtop computer. The VICAID system enables a person with a developmental disability to access pictorial instructions designed to help him or her in the accurate completion of tasks. It also provides reminders to access the instructions, and/or alerts a job coach or supervisor should the worker's interaction with the system suggest that they are having difficulty with a task. Evaluative studies show that (1) the system is more effective than alternative supports (pictorial instructions presented in booklets) in maintaining accurate task performance, (2) that the system is preferred to such booklets by most users with severe disabilities, and (3) that it can be used in real work settings. Future development of the system will require attention to be paid to issues of training job-coaches and support workers in its setting-up and maintenance.

“…For example, the studies relying on pictorial instructions tended to use a larger number of tasks than the studies using systematic prompting. With regard to the former studies, it may also be noted that those by Lancioni et al . (1995, 1998, 1999a,b, 2000b) included not only the 4–7 tasks on food preparation but several other (food‐unrelated) tasks too.…”

Background Food preparation skills are considered very relevant for people with intellectual disabilities. This paper reviewed research studies teaching these skills through the use of pictorial instructions or systematic prompting strategies. Methods Computerized and hard searches led to the identification of: 12 studies using pictorial instructions on cards; four studies using pictorial instructions through computers; seven studies using systematic prompting (time delay or prompted practice of incorrect task steps), and three studies combining time delay with cards. Results The overall training outcomes were quite encouraging. Maintenance and generalization data tended to be in line with the training outcomes. The findings for the different teaching approaches were analysed in relation to the characteristics of the participants, number and complexity of the tasks available, data collection strategies as well as relevant literature on intellectual disabilities. The suitability of the teaching approaches for different types of people and environments and some relevant issues for future research were also examined.

Task instructions for persons with severe intellectual disability: reducing the number of instruction occasions after the acquisition phase

et al. 1999

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.
