Emergency telephone calls: a multiple baseline study using instructional programming

Three women with Down's syndrome and speech difficulties were taught to discriminate emergency fire situations and subsequently how to contact, with minimal verbal requirements, an emergency agency by telephone. A procedure modelled on Engelmann and Carnine's (1982) guidelines for instructional programs was applied using a multiple baseline design across subjects. Independent ratings of each learner at post-testing and follow-up confirmed the utility of the present program.
