Our Research

Dr. Nancy E. Hall is recognized for her expertise in fluency disorders and undergraduate research. Her areas of research include the relationship between language and fluency in early language acquisition in both typically developing children and those with communication disorders. Dr. Hall served on the ASHA Joint Coordinating Committee on Evidence Based Practice, and is a past editor of Perspectives in Fluency and Fluency Disorders, the peer-reviewed publication of ASHA’s Special Interest Division in Fluency and Fluency Disorders.

Dr. Judy Perkins Walker’s research program explores prosodic deficits in adult subjects with right and left hemisphere damage. Dr. Walker is interested in the abilities of brain-damaged subjects to process and produce prosodic features that influence lexical access, syntactic parsing and the categorical assignment of questions and statements. Her research encompasses response time methodology and acoustic measurements of prosodic features. Her most recent publication, “The production of linguistic prosody by subjects with aphasia,” can be found in the Journal of Clinical Linguistics and Phonetics.

Dr. Christopher Grindrod directs the Neurolinguistics and Aphasia Research Lab in the Department of Communication Sciences and Disorders at the University of Maine. His primary area of expertise is in studying acquired language disorders to better understand how language is processed by the brain. Among the patient populations he has worked with are individuals with aphasia, patients with right hemisphere brain damage, and individuals with Parkinson’s disease. His current research examines the effect of left- vs. right-brain damage on the ability to use lexical- and sentence-level context information to guide word processing. Through this research, he hopes to shed light on brain-language relationships which will lead to improved assessment and treatment of individuals with acquired language disorders, such as aphasia. He has also recently begun studying the effects of aging on language comprehension. In this research, he uses on-line reaction time methods to investigate whether there is a slowing in the way linguistic information is processed as we age. The ultimate goal of this research is to develop interventions to potentially ward off early cognitive decline or dementia.
