Wolery, Mark; And Others – Education and Training in Mental Retardation, 1990
Four students (ages 10-14) with moderate mental retardation learned chained tasks with constant time delay and with the system of least prompts. Both strategies produced criterion-level performance; however, constant time delay was more efficient than least prompts in terms of number of sessions, percent of errors, and direct instructional time to…

Peer reviewedSpooner, Fred; And Others – Education and Treatment of Children, 1986
Variations of backward chaining--backward chaining with leap-aheads (BCLA) and reverse chaining with leap-aheads (RCLA)-- were compared with four severely retarded learners (17-32 years) who were trained on two complex vocational tasks. Learning rate for the BCLA procedure was superior to the RCLA procedure. Time to criterion differences were…
