The Interaction Of Crystallized And Fluid Abilities In Aging And Speech Perception, Avanti Dey
The Interaction Of Crystallized And Fluid Abilities In Aging And Speech Perception, Avanti Dey
Arts & Sciences Electronic Theses and Dissertations
In a series of studies, I examined the degree to which fluid and crystallized abilities contribute to and interact during speech perception. During the aging process, crystallized abilities (e.g., linguistic and word knowledge) are largely preserved, while fluid abilities involved in the online manipulation of information (e.g., working memory and inhibitory control) decline with age. Importantly, these two components are critical for successful speech perception and comprehension. While prior research has proposed that older adults rely on crystallized knowledge to compensate for cognitive deficits in difficult listening conditions, this hypothesis has not been directly tested. Younger and older adults completed …
The Feasibility Of Using Metacognitive Strategy Training To Improve Performance, Foster Participation, And Reduce Impairment Following Neurological Injury, Timothy J. Wolf
Arts & Sciences Electronic Theses and Dissertations
Executive function is central to our ability to learn and participate in everyday life activities and rehabilitation outcomes for individuals with executive dysfunction after neurological injury are poor. The impairments and performance challenges these individuals experience are typically not identified appropriately so they often do not receive adequate rehabilitation and can have significant challenges returning to complex everyday life activities. The vast majority of rehabilitation efforts to support individuals with neurological injuries with executive dysfunction are based on a restoration model that aims to improve cognitive function with the expectation that these gains will translate to everyday life. The available …
