Brief Practice


Using a multiple probe design, we examined the effects of least-to-most prompting to teach young adults with intellectual disability (ID) to locate and select items using a grocery list presented on an iPad. Sessions were conducted entirely in a community grocery store. The results indicated that participants learned to use an initial grocery list, with one participant demonstrating the ability to use a re-sequenced grocery list and a list with novel items. These results are discussed along with implications for practice.
