She also has contributed knowledge concerning the neurobiology of such disorders as specific language impairment, dyslexia, and auditory processing disorder. For more than 20 years, she has published journal articles concerning assessment methods, focusing on how norm-referenced tests can be used in valid ways to address clinical concerns. She is coauthor of the Pediatric Test of Brain InjuryTM (PTBITM; with coauthors G. Hotz, N. Helm-Estabrooks, & N.W. Nelson; Paul H. Brookes Publishing Co., 2010), which is conceptually related to the Test of Integrated Language and Literacy SkillsTM (TILLSTM); a widely used textbook on communication disorders; and more than 100 peer-reviewed journal articles, three of which have won editors’ awards.
