This manual, the second of a two-part study, addresses issues involved in behavioral interventions with low incidence, severely handicapped students. Initial chapters focus on selecting appropriate goals, writing behavioral objectives, and selecting observational systems to measure behavior change. General treatment procedures for increasing and decreasing behavior as well as for teaching new behavior are reviewed. Specific behaviors (toileting skills, self-care skills, self-stimulation, and self-injurious behavior) are considered in a fourth chapter. Techniques for maintenance and generalization of behavior change are described in chapter 5, followed, in chapter 6, by a review of adaptive equipment and electronic technology for individuals with severe physical disabilities. A final chapter presents six guidelines for implementing programs, including examining potential negative consequences of reinforcers and providing adequate training for all personnel involved in the treatment procedures.
