About the Author


Paul J. Yoder, Ph.D., Professor, Department of Special Education, Peabody College, Vanderbilt University, Nashville, Tennessee 37203

Dr. Paul Yoder has been studying the transition from prelinguistic to linguistic communication in multiple populations with disabilities for over two decades. He is a co-designer of Milieu Communication Teaching and has contributed to several studies examining the efficacy of this treatment. He teaches methods and measurement at Vanderbilt University.


Primary research activities of Frank J. Symons, Ph.D., are supported by the National Institute of Child Health and Human Development (NICHD), and they focus on improving the assessment and treatment of severe self-injurious behavior among individuals with developmental disabilities and pervasive developmental disorders. Dr. Symons was a research scientist at the Frank Porter Graham Child Development Center at the University of North Carolina at Chapel Hill and a postdoctoral fellow at the John F. Kennedy Center at the Peabody College of Vanderbilt University in Nashville, Tennessee. He is the co-author of Behavioral Observation: Technology and Applications in Developmental Disabilities (Paul H. Brookes Publishing Co., 2000).
