Four telephone-answering problems were identified. Following baseline observations, 6 mentally retarded students were exposed to a treatment package consisting of verbal and visual prompts, reinforcement, and rehearsal opportunities within the context of a Multiple-Baseline, Across-Problems X Subjects design. All students learned to criterion the problems to which they were exposed; however, large individual differences in performance were observed during all phases of the study. Posttraining and follow-up probes revealed, with few exceptions, good retention. Transfer of training occurred between problems, and generalization of treatment occurred between sex of caller and style of caller request.
