Dr. Abbeduto spent several years as a research scientist at Vanderbilt University's Kennedy Center for Research on Education and Human Development before joining our faculty in 1987. He has received numerous grants from the National Institutes of Health to support his research on the language and communication development of children, adolescents, and young adults with cognitive disabilities. Dr. Abbeduto is also a Associate Director for Behavioral Sciences at the University's Waisman Center on Mental Retardation and Human Development, Faculty Coordinator of its Research Participation Core, and a Core Investigator in its Communication Processes Unit. He also is Director of two federally funded training programs on behavioral research in developmental disabilities, one for advanced graduate students and the other for post-doctoral fellows. In recognition for his contributions to the field of developmental disabilities, Dr. Abbeduto was awarded fellow status by the American Association on Mental Retardation in 2000. In 1996, he received the Emil A. Steiger Award for distinguished teaching from the University. His teaching interests include language development, language disorders, and developmental disabilities. He recently coauthored (with S. N. Elliott) Guide to Human Development for Future Educators and edited Taking Sides: Clashing Views on Controversial Issues in Educational Psychology, each of which is a popular textbook for undergraduate classes in education and human development.

RESEARCH STATEMENT
"My research interests are largely in the area of language development. At present, I am most interested in children's emerging ability to participate actively as speakers and listeners in discourse.

I have studied a variety of discourse behaviors, including the use of context to make decisions about what a sentence means and what form a message should take, the repair of misunderstandings, and the tracking of shared information over the course of the discourse. In an attempt to learn what skills are needed to engage in such behaviors, we have studied individuals who are slow to develop discourse skills; namely, those with cognitive disabilities.

I am also interested in examining genetic contributions to this development and thus, have focused on the development of persons with genetic syndromes associated with cognitive disabilities, such as Down syndrome and fragile X syndrome.

Recently, I have begun to examine the ways in which families influence and are influenced by the challenges that face their sons and daughters with cognitive disabilities."
