“Auditory Temporal Processes in Aging”
Older people experience great difficulty understanding speech, especially accented English, and this problem is expected to increase with the influx of immigrants who provide services to the elderly population. The research examines the underlying factors that contribute to older listeners' difficulty understanding accented speech, including those associated with age-related hearing loss, changes in processing in auditory pathways in the brain, and general cognitive decline. The investigation also evaluates the efficacy of training strategies to improve understanding of accented English by older people. Outcomes of this research are expected to improve communication between senior citizens and those with whom they interact daily, and thereby improve quality of life for the older segment of the Nation's population.
