An Examination Of The Relation Between Memory Self-Efficacy And Working Memory Within The Cognitive Reserve Framework, Genna Marie Mashinchi Ma

Graduate Student Theses, Dissertations, & Professional Papers

Dementia has been found to negatively affect multiple aspects of cognitive functioning. Despite an increasing prevalence of cognitive decline, many aging adults do not experience reduced cognitive functioning. The reason as to why some experience cognitive decline and others do not is still unclear. One leading theory thought to explain this phenomenon is the cognitive reserve theory (CR), which proposes that certain lifestyle factors (e.g., educational attainment, occupational attainment, and leisure activity participation) prolong one’s cognitive functioning and reduce the risk of cognitive decline. Memory self-efficacy (MSE), defined as one’s beliefs in their memory ability, was found to be positively …

Biobehavioral Predictors Of Executive Function Decline In Mid- And Late Life Adults, Cali Anne Caughie

Graduate Student Theses, Dissertations, & Professional Papers

Using data from the Midlife in the United States (MIDUS) Longitudinal Study of Health and Well-Being, this study examined high frequency heart rate variability as a longitudinal predictor of cognitive change in key executive function domains: inhibition, shifting, and updating. This study further explored the interactions between HF HRV and important health factors (inflammation, stress, sleep, and mood and anxiety) in predicting executive function decline.

The results of this investigation demonstrated that while high frequency heart rate variability and inhibition decline were correlated, HF HRV was not a significant predictor of decline in any executive function. However, results did show …

The Alphaback: A Novel Processing Speed Test, Meredith Kathleen Reynolds

Graduate Student Theses, Dissertations, & Professional Papers

Processing speed is a sensitive indicator of normal aging, as well as neurological impairment. Despite the importance of assessing this cognitive domain in neuropsychological assessments, few tests of processing speed are available. The purpose of the current study was to establish the operating characteristics, as well as the convergent and divergent validity of a novel processing speed test, the Alphaback, on a healthy college student population (N = 91). The Alphaback is a 2 min computerized task in which examinees must orally state the alphabetical letter that precedes the letter presented on a screen as fast as possible. Cognitive tests …

Health Issues And Aging In American Indian Older Adults: Resilience Through Adversity, Ennis F. Vaile

Graduate Student Theses, Dissertations, & Professional Papers

The average life expectancy of American Indian (AI) older adults has paralleled mainstream aging trends and is set to continue growing as global increases in longevity continue to improve (Jervis, Boland, & Fickenscher, 2010). However, the disproportionately high levels of chronic health conditions (e.g., diabetes, hypertension, cerebrovascular diseases) observed in this group may outstrip the coping resources of some individuals, potentially leading to unsuccessful aging outcomes such as adverse mental health outcomes (specifically depression). As described in Goins and Pilkerton (2010, p. 346), comparatively higher rates of chronic health conditions have created an “expansion of morbidity,” where American Indians are …

Age At Death Estimation From The Sacral Side Of The Sacroiliac Joint, Misty Marie Keahi Rego

Graduate Student Theses, Dissertations, & Professional Papers

This thesis presents a new method of age estimation in adult human skeletal remains based on age related degenerative changes of the sacral side of the sacro iliac joint. It is inspired by the existing method of aging based on age related degenerative changes of the iliac side of the sacro iliac joint developed by Lovejoy et al. (1985). This new method uses a ten-year-wide incremental scale of age estimation. The development and testing of this method was done using the Documented Collection from the University of New Mexico's Maxwell Museum of Anthropology. Results suggest that utilizing sacral deterioration to …
