The third in a series of literature reviews, this monograph presents three articles on skill generalization among individuals with severe disabilities. Kathleen A. Liberty analyzes the results of 15 studies to determine how teaching self-control affected students' performance in training and generalization, "Behavior-Control of Stimulus Events to Facilitate Generalization." Joan E. Kayser and Felix F. Billingsley follow with "Generalization: A Review of Assessment Procedures" which examined 62 studies using generalization assessment procedures from 1970-1975 and 1980-1985. In the final article, "Extending Research Findings: The Role of Staff Development and Evaluation," Valerie Lynch and Frances McCarty consider factors in designing staff development and in conducting comprehensive evaluation plans.
