Memory For Emotional Expressions In Adults With Acquired Brain Injuries, Lauren Jeanne Radigan
Memory For Emotional Expressions In Adults With Acquired Brain Injuries, Lauren Jeanne Radigan
Wayne State University Dissertations
Introduction: Memory for emotions expressed by others forms the continuity that characterizes unique and intimate relationships. Successful memory for facial expressions requires the ability to remember the identity of the face (who showed the emotion) as well as the emotion (which emotion they showed). People with acquired brain injuries (ABI) frequently have problems with social cognition, which involves understanding cues that communicate emotional and interpersonal information. ABI is commonly associated with trouble perceiving emotional expressions and recognizing the identity of faces; however, research on memory for emotions after ABI is sparse. This study examined cognitive and emotional characteristics that contribute …
Hearing Loss And Verbal Memory Assessment In Older Adults, Christina G. Wong
Hearing Loss And Verbal Memory Assessment In Older Adults, Christina G. Wong
Wayne State University Dissertations
Prior research has found that adults with hearing loss perform worse on cognitive testing than adults without hearing loss, and some studies have suggested that hearing loss is associated with dementia. Heavy emphasis on tests involving auditory stimuli for memory assessment may result in overdiagnosis of cognitive impairment in individuals with hearing loss. The present study compared visual and auditory versions of a verbal memory test among older adults with and without hearing loss. Forty-one adults with moderate-to-severe, sensorineural hearing loss (HL) and 41 age-matched adults with normal hearing (NH) participated. Age ranged from 55 – 80 years. They completed …
Engagement In Activities And Cognitive Functioning Among Older Adults In The Health And Retirement Study, Pamela Emily May
Engagement In Activities And Cognitive Functioning Among Older Adults In The Health And Retirement Study, Pamela Emily May
Wayne State University Dissertations
The goal of this dissertation is to examine the effect of cognitive and social activities on cognitive performance and health conditions in a national sample of older adults from the Health and Retirement Study (HRS). This dissertation first aimed to identify longitudinal relations between activity frequency and cognitive functioning. Two hypotheses were tested, baseline activity frequency predicts change in cognitive functioning over time, and baseline cognitive performance predicts change in activity frequency over time. The dissertation’s second aim was to identify links between activity frequency and cognitive trajectories. The third aim was to identify longitudinal relations between activity frequency and …
Changes In Cerebral White Matter, Vascular Risk And Cognition Across The Adult Lifespan, Andrew Robert Bender
Changes In Cerebral White Matter, Vascular Risk And Cognition Across The Adult Lifespan, Andrew Robert Bender
Wayne State University Dissertations
Numerous studies over the past decade have used diffusion tensor imaging (DTI) to examine associations between age, diffusion and anisotropy measures of cerebral white matter (WM), and cognitive performance. However, few have examined relationships between intra-individual change in DTI measures of WM and cognitive function. It is possible that the extant cross-sectional findings are a poor representation of age-related change in WM and cognition. The present study used latent difference-score modeling (LDM) to assess change over two years in DTI indices fractional anisotropy (FA), radial diffusivity (DR), axial diffusivity (DA) and mean diffusivity (MD). In addition, we examined the effects …
Assessment Of Memory Function And Effort Using The Wechsler Memory Scale - 4th Edition, Justin B. Miller
Assessment Of Memory Function And Effort Using The Wechsler Memory Scale - 4th Edition, Justin B. Miller
Wayne State University Dissertations
Even the most psychometrically sound measures are sensitive to the level of effort put forth by the examinee and their intent. This is especially true for measures of memory functioning that are a common target of negative response bias and withholding effort. The aim of the present study was to develop methods for detecting these behaviors for the current edition of the Wechsler Memory Scale, 4th Edition (WMS-IV) using a community sample of healthy adults coached to simulate traumatic brain injury (TBI) and a sample of bona fide TBI survivors. The primary analytic strategy involved generation of prediction models to …
