Ralf Schlosser


Professor; Assistant Dean of Research

Communication Sciences and Disorders


Dr. Ralf W. Schlosser’s research interests are related to the efficacy of interventions in augmentative and alternative communication (AAC) particularly as they relate to the role of speech output and different graphic symbol sets for individuals with developmental disabilities.

He is also concerned with methodological issues in conducting efficacy research, including research design (in particular, single-subject experimental designs) and research synthesis (i.e., meta-analysis).

Together with Dr. Doreen M. Blischak of the University of Florida, he is currently engaged in a research project on the effects of synthetic speech output and visual display feedback on spelling in children with autism.
