This program addresses the application of computer-controlled electronic and mechanical equipment in the vocational training of mentally retarded persons. Proposed is a research and development effort to embody the training-system concept in modular hardware and software for versatile manual workstations. The modules, in conjunction with other specialized vocational materials, can be readily adapted to training assistance in a broad variety of tasks involving such basic skills as attending, counting, accurate placement of items, packaging, and in-seat behavior. Configuration of a workstation and system programming for training on specific task sequences can be accomplished by instructors without experience in computers or electronics. Each training setup provides for the automatic acquisition of data that tracks client performance and progress.As a first step in implementing the system and evaluating it in a realistic setting, a basic workstation will be assembled. It will be used initially to assist in training clients in the fabrication of memo pads, a present vocational activity of one of the many ongoing programs now serving handicapped persons in Massachusetts. The proposed workstation will be evaluated at that program with the help of the existing clients and staff.National Institute of Child Health and Human Development (NICHD)
