Neural Activity Reveals Effects Of Aging On Inhibitory Processes During Word Retrieval, Ranjini Mohan

Open Access Dissertations

Word retrieval difficulties are one of the most frustrating problems in older adults. Poorer access to phonological (speech sound) representation of the target word has been postulated as the underlying deficit, supported by findings of improvement in word retrieval after phonological priming. But the great variability in naming performance among older adults may reflect cognitive scaffolding or compensatory neurophysiological processes related to maintenance or decline of naming abilities. In order better understand aging effects in the underlying neurophysiological changes associated with phonological retrieval, the present study examined electrophysiological correlates of phonological priming and word retrieval in adults across the lifespan. …
