Comparison of Treatments to Teach Number Matching Skills to Adults with Moderate Mental Retardation
The effectiveness of the Dial-A-Phone (D-A-P) instructional package plus a least intrusive prompt hierarchy was compared with that of a least intrusive prompt hierarchy alone for teaching adults with developmental disabilities (DVDs) to match digits of personal phone numbers with digits on a rotary dial telephone. Instructional programs were administered to a 36-yr-old man with moderate DVDs and to a 44-yr-old man with Down syndrome and severe DVDs. The dependent variable was the percentage of digits matched independently per session (21 digits per session). Results suggest that although a least intrusive prompt hierarchy alone produced findings similar to the D-A-P plus prompts procedure for 1 S, the D-A-P plus prompts package was the most effective in helping both Ss to match digits independently.
