This volume has two purposes. The first is to summarize, substantiate, and extend current knowledge on the development of children with high incidence disabilities--most notably, learning disabilities, behavioral disorders, and mild mental retardation. The second is to honor the career of Professor Barbara K. Keogh and her contributions to the developmental study of children with high incidence disabilities. Internationally recognized for her accomplishments, Keogh is esteemed for her originality and clarity of thought. For nearly forty years, she has set an extraordinary model of analytic rigor combined with a kind and generous manner that inspires, supports, and sets an exacting standard of scholarship. The contributing authors to this volume represent only a fraction of the students and scholars touched by her distinguished career.

In conceiving this volume, the editors sought to represent the topics, problems, and issues to which Keogh has devoted herself. They invited chapters that summarize what is known about the high incidence handicapping conditions that her research has mainly addressed and sought to reflect the probing, questioning style that she brings to her own work. Researchers, policymakers, and graduate students in special education and associated disciplines who seek to stay current will find this volume crucial reading.
