Generalized use of a handheld prompting system.
This study determined the effectiveness of a commercially produced handheld computer, as a prompting system in facilitating the generalization and increasing the probability of long-term maintenance of vocational skills by adolescents with moderate intellectual disabilities. Four students successfully used the system in learning a task and then generalized the use of the prompting system to complete increasingly more complex tasks. Task performance was maintained at a 100% level for up to 9 weeks.
