Memory-Based Viewing: A Potential Marker Of Pathological Aging, Jenna Blujus
Memory-Based Viewing: A Potential Marker Of Pathological Aging, Jenna Blujus
Theses and Dissertations
Markers of cognitive impairment are needed to distinguish normal from pathological aging prior to the onset of clinical symptomology to improve Alzheimer’s disease (AD) treatment or prevention efforts. AD pathology is believed to develop years or even decades prior to diagnosis in medial temporal lobe subregions that provide input to the hippocampus (Braak & Braak, 1991), disrupting the ability of the hippocampus to bind individual elements of an experience to form cohesive memory representations. Eye movement behavior is a sensitive index of learning and effects of memory on eye movements have been shown to emerge rapidly (within 500-750ms of stimuli …

From Sunrise To Sunset: A Lifespan Approach To Understanding The Mental Health Of A Subset Of American Farmers, Janna L. Imel
From Sunrise To Sunset: A Lifespan Approach To Understanding The Mental Health Of A Subset Of American Farmers, Janna L. Imel
Theses and Dissertations
Prior research has indicated higher risk of suicide for farmers and identified depression and anxiety as mental health concerns, though the majority of research was conducted in the 1980s-1990s. In today’s economic, social, and political climate, farmers are exposed to situations and stressors reminiscent of the 1980s Farm Crisis. An added risk is the aging workforce of farmers, as age-related conditions can make farming even riskier. This study investigated the mental health of a subset of American farmers by exploring farm-related stressors, coping mechanisms, and mental health outcomes. Dispositional mindfulness was explored as a specific coping mechanism. Participants (N …
Loneliness And Sleep Disturbance In Older Americans, Sarah C. Griffin
Loneliness And Sleep Disturbance In Older Americans, Sarah C. Griffin
Theses and Dissertations
Loneliness is a risk factor for premature mortality but the mechanics of this relationship remain obscure. A potential mechanism is sleep disturbance. The present study aimed to examine the association between loneliness and sleep disturbance, evaluate loneliness as a risk factor for sleep disturbance and vice-versa, model effects between loneliness and sleep disturbance over time, and evaluate a mediation model of loneliness, sleep disturbance, and health. Data came from the 2006-2012 waves of the Health and Retirement Study, a nationally-representative study of older Americans; participants > 65 were included (n=11,400). Analyses included (i) linear regressions accounting for complex sampling and (ii) …
