The report describes second year efforts of a 5-year investigation of skill generalization among severely handicapped students. An overview section introduces the Washington Research Organization, noting its administration and management and its major emphasis on the collection of descritptive data and laboratory research, research in natural educational settings, evaluation, and communication. Basic research concepts in generalization are reviewed. The four approaches to generalization are summarized: (1) studies in ecological variables, (2) studies in performance patterns, (3) studies in self control, and (4) studies in strategy implementation. The second part addresses each of the four generalization strategies by means of research reviews: training in the natural environment and skill generalization, response competition and generalization, teaching retarded students to reinforce their own behavior, and social skills training.
