Aging and Development
Speech comprehension is determined both by the nature of the acoustic signal (bottom-up processing, or what you actually hear) and by the context of the speech that produces expectations for what you'll hear (top-down processing, such as your memory for what you heard previous). As aging is associated with degradation in both hearing and memory abilities, older adults develop difficulties understanding what people are saying. As a member of the Speech & Hearing Lab, I have investigated the extent to which age-related declines in both hearing and memory contribute to older adults' declining speech comprehension ability.
