Present and Future Possibilities for Defining a Phenotype for Specific Language Impairment

htagerf{at}shriver.org

This brief report summarizes a workshop that was held at the National Institutes of Health in April 1998. The goal of the workshop was to further the development of a definition for the phenotype of specific language impairment (SLI). The report includes a discussion of research recommendations that will refine our current views of the definition of the SLI phenotype and sets out priority areas that are in need of further study to help advance understanding of this complex languagebased disorder.

Note:

Special Report from the Workshop on Defining the Phenotype for Specific Language Impairment, held April 27–28, 1998, and sponsored by the National Institute on Deafness and Other Communication Disorders, the National Institute of Child Health and Human Development, and the Office of Behavioral and Social Sciences Research at NIH. Contributors included Dorothy Aram, Hugh Catts, Susan Ellis Weismer, Jack Fletcher, Susan Folstein, Judith Johnston, Laurence Leonard, Reid Lyon, Jon Miller, Robin Morris, Mabel Rice, Donna Thal, Bruce Tomblin, Julie Washington, and Beverly Wulfeck.
