This study was aimed at assessing the impact of frequent versus nonfrequent verbal prompts, delivered unobtrusively, on the task performance of two adults with severe intellectual disability. The prompts were delivered through a small pocket device with an earpiece. This device was linked via radio to a portable computer-aided system that also served for presenting the task instructions (i.e., pictorial representations of the task steps). Data indicated that the frequent prompts condition fostered a higher level of on-task behavior and correct task responding. Implications of the findings are discussed.
