Provided is the step-by-step curriculum of the Language Development-Perceptual Motor Training Program designed to improve the functioning level of each child and to provide staff with methods for dealing with severely retarded children on the level of the children's communicative abilities. Program areas, which are color-coded for the user's convenience, include reinforcement, motor imitation, receptive vocabulary, conceptual receptive vocabulary, and verbal imitation. Each program area consists of a series of developmental steps; and each step includes explanations of tasks to be completed, procedure, reinforcers, materials needed, and suggested place for the activity. A final section lists and illustrates sensorimotor training materials. Authors suggest that this program would be feasible for use by parents and teachers of severely mentally retarded children outside the institutional setting. (Author/SB)
