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 adults
with left or right hemisphere brain-damage, traumatic brain injury, or
progressive diseases such as Alzheimer's, Huntington's, and Parkinson's
Diseases.
Current projects compare dual-task performances of adults with
aphasia and adults with right hemisphere brain damage to examine whether
side of lesion or brain damage in general is most detrimental to
attentional skills and to associations between attention and language
processes.
Other interests include relating patterns of discourse
production (i.e., syntactic, semantic, and pragmatic levels) in
Huntington's and Parkinson's Diseases to the degree of cognitive,
behavioral, and motor impairment to identify possible underlying sources of
communication impairment, and consequently to develop interventions to
improve or maintain effective interaction between brain-damaged patients
and their daily communicative partners.
Another ongoing project has been
designed to resolve the clinical diagnostic dilemma of distinguishing reversible pseudodementia from the irreversible dementing illness,
Alzheimer's disease by quantitatively and qualitatively comparing the
language and attention skills of elderly adults with these disorders.
