Speech pathology and linguistics have, as sciences, experienced a parallel development over the past fifty years. Although these disciplines have traditionally been separated, they have common areas of concern, and there are indications of a growing interest on the part of speech pathologists in such linguistic subfields as sociolinguistics, psycholinguistics, and neurolinguistics. Speech and hearing publications are paying attention to theoretical and methodological linguistic models, and descriptions of communication disorders are using linguistic paradigms as a basis. Given the interest of speech pathology in linguistics, there is both an obligation and an opportunity for linguists to define new roles for themselves within speech pathology. This requires the identification of common areas and methods by which the linguist can adapt linguistic concerns so that they are meaningful to the speech pathologist. Areas of common interest include communication disorders, phonetics, language acquisition, and language variation. Linguists may have to expand their data base to include the particular interests of speech pathology; they may need background information in areas not traditionally stressed in linguistics; and they must understand the goals of speech pathology as a professional field.
