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…

A 20-year-old institutionalized nonverbal male with Down's Syndrome was trained via total task chain training, verbal prompts, and self-reinforcements to acquire skills of a busperson at a community restaurant. The S acquired and performed skills at a situationally appropriate rate. (CL)

The study with four adults with moderate and severe mental handicaps found that both backward and concurrent chaining training strategies were equally effective in teaching use of a fast food restaurant and a supermarket. (Author/DB)

The study with four pairs of developmentally delayed preschoolers found a slight but discernible advantage of using the time delay procedure rather than the increasing assistance procedure to teach complex, chained-response self-help skills. Considerable learning also resulted solely from the observation of instruction. (Author/DB)

The handbook describes a method of teaching communication skills to students with severe disabilities (severely and profoundly retarded, trainable mentally retarded, autistic, deaf blind, and severely multihandicapped). In the interrupted behavior chain procedure, a routinized activity in a natural setting is interrupted and the child is taught to…

Whole task training and graduated guidance were used to teach independent dressing skills to two developmentally disabled 4-year-olds. After the boys acquired basic dressing skills, additional practice (fluency training) elevated their performance to socially validated rates. Follow-up showed that the skills were maintained and generalized to…
