Adult Cognition and Language Laboratory

Department of Speech and Hearing Science
Indiana University
Lab Director - Dr. Laura Murray


Lab Director:

Laura Murray Ph.D. CCC-SLP ( Dr. Murray's general research interest is the cognitive and neural bases of adult neurogenic communication disorders. She is particularly interested in determining how deficits in cognitive processes other than language, such as attention and memory, interact with communication skills. Her work describes and compares the integrity of language and cognition in normal-aging adults and in adults with left or right hemisphere brain-damage, traumatic brain injury, or progressive diseases such as Alzheimer's, Huntington's, and Parkinson's Diseases.

Doctoral Students:

Toshikazu Ikuta M.A., ( is ABD in the Program in Neuroscience and Department of Linguistics with primary research interets in the roles of neurotransmitters in linguistic processes.

Bonnie Lorenzen M.A., ( is a second-year doctoral student in the Department of Speech and Hearing Sciences with primary research/clinical interest in acquired disorders of language and cognition as they relate to bilingual speakers, and the significance of bilingualism on clinical intervention.

Hye-Young Kim M.A. ( is a ABD in the Department of Speech and Hearing Sciences, and her current research interests include the effects of alternative treatments for aphasic patients, particularly Soojichim (Korean non-invasive hand acupuncture), when combined with traditional language therapy. Her general research interests include deficits in speech comprehension and production and writing in persons who have suffered stroke.

Olga Rey ( is ABD in the Neural Science Program with primary research interests are in the neural correlates of executive changes observed in normal and pathological aging. She is currently working on a project to study the influence of age and educational level on executive tasks with linguistic vs. non-linguistic content.

Amy Scott B.S. Ed. ( is a fourth-year doctoral student and Women in Science Fellow in the Department of Speech and Hearing Sciences.


Jacob Kean M.A., CCC-SLP ( is currently a visiting at the Department of Speech and Hearing Sciences with primary research interests in disturbances of the sound system in aphasia, the organization of the lexicon and patterns of disruption, and functional cognitive/linguistic treatment for those with traumatic brain injury.

Jamie Mayer M.A., CCC-SLP ( is a visiting aassistant professor at Northern Illinois University with primary research/clinical interest are acquired disorders of language and cognition, the interaction between domain-specific and domain-general processes in normal and disordered language/cognition, and the significance of this interaction with respect to the nature and treatment of aphasia.
