Comparing Gains And Losses: Examining The Effects Of Incentives On Working Memory Capacity And Motivational Processes In Older Adults, Julie Q. Pham
Comparing Gains And Losses: Examining The Effects Of Incentives On Working Memory Capacity And Motivational Processes In Older Adults, Julie Q. Pham
Psychology Theses and Dissertations
Working memory is critical for the storage and maintenance of information but is susceptible to age-related changes. Prior studies have shown that incentives can be used to successfully modulate cognition in older age. However, research has largely focused on the use of reward incentives. Less is understood about the motivational processes of avoiding losses and whether this can also improve working memory capacity. Given that an aversion to losses may become more salient with age, it is important to determine whether these motivational shifts are reflected in how older adults attend to and store information. The current study compared how …
Parkinson’S Disease And Processing Speed Theory Does Processing Speed Mediate Higher-Order Cognitive Functioning?, Priscilla Cuellar-Rocha
Parkinson’S Disease And Processing Speed Theory Does Processing Speed Mediate Higher-Order Cognitive Functioning?, Priscilla Cuellar-Rocha
Electronic Theses, Projects, and Dissertations
Parkinson’s disease (PD) is a neurodegenerative disorder resulting in both motor and cognitive deficits. Salthouse (1990) proposed the Information Processing Speed (IPS) Theory that a reduced cognitive processing speed is a significant factor that accounts for the negative relationship between age-related variance and cognition. Parkinson’s is an idiopathic disorder, meaning that the cause is unknown, with most patients being 60 years and older. If the IPS theory suggests that an increased age affects the slowing of IPS, which then impairs cognition, PD, a disorder involving older adults, should also follow this pattern. However, no studies have assessed the IPS theory …
Cognitive Differences In Parkinson’S Disease With Amyloid Positivity And Negativity, Kenya Luna
Cognitive Differences In Parkinson’S Disease With Amyloid Positivity And Negativity, Kenya Luna
Electronic Theses, Projects, and Dissertations
In Parkinson’s Disease (PD), research has shifted to investigate how biomarkers commonly seen in Alzheimer’s Disease (AD), such as amyloid beta (AB), may be associated with cognitive functioning in PD. AB is considered a reliable biomarker for AD pathology, however in PD there is a lacking biomarker that can accurately reflect severity of cognitive impairment. AD research has shown an association between low AB and cognitive decline, but the data in PD has mixed results. Most studies that analyze cognitive decline and biomarkers do not use a cutoff level and the few that do have a threshold vary greatly in …
Factors Associated With Functioning In Older Black Adults, Katrail D. Davis
Factors Associated With Functioning In Older Black Adults, Katrail D. Davis
LSU Master's Theses
Activities of daily living can be simple tasks such as bathing, showering, toileting or as complex as managing finances, driving, and preparing meals. Independence in everyday functioning has been associated with successful aging and declines in functioning may be indicative of pathological cognitive decline. Social determinants of health, like economic status and access to health care, also play a role in everyday functioning. Understanding these factors are of particular importance for older Black adults who have had long-standing disparate access to care, education, and treatments. The current study aimed to evaluate social determinants of health, more specifically social engagement, as …

The interrelationships among long-term ambient air pollution exposure, emotional distress and cognitive decline in older adulthood remain unclear. Long-term exposure may impact cognitive performance and subsequently impact emotional health. Conversely, exposure may initially be associated with emotional distress followed by declines in cognitive performance. Here we tested the inter-relationship between global cognitive ability, emotional distress, and exposure to PM2.5 (particulate matter with aerodynamic diameter 2 (nitrogen dioxide) in 6118 older women (aged 70.6 ± 3.8 years) from the Women’s Health Initiative Memory Study. Annual exposure to PM2.5 (interquartile range [IQR] = 3.37 μg/m3) and NO2 (IQR …
The Biological, Psychological, Cognitive, And Social Perspectives On Aging: The Design Of A Healthy Aging Program For Older Adults, Melissa Santiago
The Biological, Psychological, Cognitive, And Social Perspectives On Aging: The Design Of A Healthy Aging Program For Older Adults, Melissa Santiago
Dissertations
Aging is an inevitable process, accompanied by changes in physiological, cognitive, psychological, and social facets. Researchers have investigated the physiological, cognitive, psychological, and social risk factors associated with aging and have encouraged the use of physical activity, cognitive training, and dietary interventions to alleviate risk factors. However, holistic programs dedicated to promoting successful aging among older adults are uncommon. This review sought to promote successful aging by identifying physiological, cognitive, psychological, and social risk factors that affect older adults and develop a comprehensive program to holistically mitigate these risk factors. Risk factors associated with unsuccessful aging include the development of …
