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 …
Death With Dignity: Queer Representation In Deathcare Systems, Esmé Ringelstetter
Death With Dignity: Queer Representation In Deathcare Systems, Esmé Ringelstetter
University Honors Theses
This thesis examines the ways that elderly members of the LGBT community lack representation within deathcare systems. Currently, the LGBT community is vastly underrepresented in research relating to the dying process and deathcare. This lack of representation creates barriers for LGBT individuals at the end of their lives and creates difficult end-of-life experiences. I utilized previous research that studied how LGBT populations interact with and are treated by a variety of death care-related systems, including health systems, legal systems, and therapeutic systems. This research highlighted the need for the LGBT community to be better represented within both research relating to …
Adult Age Differences In Response To Sociomoral Violations, Alyssa R. Minton
Adult Age Differences In Response To Sociomoral Violations, Alyssa R. Minton
College of Science and Health Theses and Dissertations
Moral judgments and emotional reactions to sociomoral violations are heavily impacted by a perpetrator’s intentions, as malicious intent poses a threat to social harmony. Given that older adults are more motivated to maintain interpersonal harmony relative to younger adults, older adults may be more reactive to malicious intentions. In five studies, I investigated adult age differences in moral judgments and emotional reactions to sociomoral violations. In Studies 1-3, participants read scenarios in which a perpetrator either (a) desired to harm another but nothing happened, or (b) harmed another accidentally without malicious intent. Study 2 incorporated additional scenarios designed to evoke …
A Qualitative Analysis Of Community-Dwelling Older Adults’ Perspectives Of Elderspeak, Katelynn Shimanski
A Qualitative Analysis Of Community-Dwelling Older Adults’ Perspectives Of Elderspeak, Katelynn Shimanski
All Graduate Theses, Dissertations, and Other Capstone Projects
Compared to other forms of discrimination, ageism, and specific forms of ageism such as elderspeak are understudied. Despite the fact that the majority of older adults are community-dwelling, much of the existing literature on elderspeak focuses on caregiver perceptions on elderspeak occurring in assisted living facilities and nursing homes. The present study analyzed community dwelling older adult’s perceptions of elderspeak using their personal examples of experiences of elderspeak. Results indicated that the majority of participants had negative perceptions of elderspeak that would likely not be influenced by changes in contextual factors such as setting, relationship to the speaker, and gender …
An Examination Of The Relation Between Memory Self-Efficacy And Working Memory Within The Cognitive Reserve Framework, Genna Marie Mashinchi Ma
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 …
Illness Intrusiveness And Psychosocial Adjustment Among Older Adults With Multimorbidity, Irina Mindlis
Illness Intrusiveness And Psychosocial Adjustment Among Older Adults With Multimorbidity, Irina Mindlis
Dissertations, Theses, and Capstone Projects
Given the high prevalence of multimorbidity (MM) among older adults and the exponential growth of the older adult U.S. population, identifying factors that can lessen depressive symptoms and improve quality of life (QOL) in this population is timely and important. While it is well established that MM is associated with greater depressive symptoms and poorer QOL (Li et al., 2016; Makovski et al., 2019; Marengoni et al., 2011; Read et al., 2017), the mechanisms underlying these relationships remain understudied. The illness intrusiveness model (Devins et al., 1984) proposes that stressors posed by diseases (disease-related factors) and their treatments (treatment-related factors) …
Examining Age-Related Enhancement Of Multisensory Gain: The Role Of Sensory Decline And Inverse Effectiveness, Laura C. Schneeberger
Examining Age-Related Enhancement Of Multisensory Gain: The Role Of Sensory Decline And Inverse Effectiveness, Laura C. Schneeberger
Electronic Thesis and Dissertation Repository
Older adults experience a greater benefit from multisensory integration than their younger counterparts, but it is unclear why. One hypothesis is that age-related sensory decline weakens unisensory stimulus effectiveness, producing a boost in multisensory gain through inverse effectiveness. Many previous studies present stimuli at the same intensity for both younger and older adults (i.e., stimulus-matched), as opposed to accounting for each participant’s unique perceptual ability (i.e., perception-matched). This makes it difficult to discern the source of age-related differences in multisensory gain. Through a combination of stimulus-matched and perception-matched tasks, I found that older adults exhibit enhanced multisensory gain at low …
Investigating The Roles Of The Dorsal And Ventral Striatum In Humor Comprehension And Appreciation Throughout Health, Aging, And Parkinson’S Disease, Maggie Prenger
Electronic Thesis and Dissertation Repository
Humor processing is thought to involve two distinct components. The first, humor comprehension, involves detecting and resolving incongruities that are present within a humorous stimulus. This is related to cognitive processes such as ambiguity resolution, response inhibition, working memory, and cognitive flexibility, functions that are mediated in part by the dorsal portion of the striatum (DS). Humor appreciation, on the other hand, refers to the subjective amusement and mirth that one experiences in response to a joke. This is related to reward processing, which implicates the ventral portion of the striatum (VS). Across three separate studies, we investigated the involvement …
Assessing The Correlation Between The Socioeconomic Level And Cognitive Function Among Older Adults In Egypt, Macy Abougabal
Assessing The Correlation Between The Socioeconomic Level And Cognitive Function Among Older Adults In Egypt, Macy Abougabal
Theses and Dissertations
The number of older adults is increasing worldwide at an unprecedented rate. Some countries began to understand the challenges of aging, while others are still at the stage of comprehending the true dimensions of the situation. There is a global focus on aging research to appropriately mitigate the negative impact of aging and cognitive decline. Not only that dementia add economic pressure on governments, it also increase the psychological and physical burden of the caregivers. Scholars have previously studied socioeconomic level in three variables, namely work, education, and income, and their relationship with cognitive function. It was concluded that the …
The Age Of Connection: Interdependent Self-Construal Links Age And Prosociality, Jason Snyder
The Age Of Connection: Interdependent Self-Construal Links Age And Prosociality, Jason Snyder
College of Science and Health Theses and Dissertations
Theories of aging have major implications for age differences in the self-concept across the adult lifespan that remain largely untested. Here, I propose a new perspective that draws from prominent aging theories to argue that people come to adopt a more interdependent self-construal with age as social environments become increasingly interdependent. Accordingly, I explain how ontogenetic development across the adult lifespan may emphasize interdependent social environments and subsequently encourage one to adopt a more interdependent self, explore how this perspective dovetails with prominent aging theories, and apply this perspective within the context of aging and prosocial behavior to support three …
Predictive Abilities Of Neuropsychological Measures On Functional Outcomes In The Mild Cognitive Impairment (Mci) And Dementia Populations, Morgan Bare
PCOM Psychology Dissertations
During the aging process, a decline in ability to perform everyday tasks is commonly observed. This is increasingly so for those with dementia and is a diagnostic requirement. These daily tasks require certain cognitive skills which can be measured by various neuropsychological measures. The purpose of this study is to examine which neuropsychological measures are able to detect various deficits in self-reported activities of daily living (ADL) and instrumental activities of daily living (IADL) in individuals with mild cognitive impairment (MCI) and dementia. It is hypothesized that Trail Making Test– B (TMT-B) would be the most sensitive predictor in functional …
Changing Public Perception Of Dementia: The Effect And Credibility Of Three Informational Models., Diana Hedrick
Changing Public Perception Of Dementia: The Effect And Credibility Of Three Informational Models., Diana Hedrick
Electronic Theses and Dissertations
Background: Since the 1970s, Alzheimer’s disease and dementia have been portrayed in a medicalized, symptom-focused manner to help spread awareness, improve diagnosis, and push for treatment research. In recent decades, there has been movement towards a biopsychosocial, person-centered approach that considers social and psychological factors that interact with biological diseases processes. Common biopsychosocial approaches retain an emphasis on deficits and symptoms. New research has integrated positive psychology constructs and dementia. This integration of positive psychology principles and dementia care and research has the potential to more accurately capture the experience of having dementia. Objectives: This dissertation tested how the portrayal …
Correlates Of Psychological Well-Being In Older Adults With Treatment-Resistant Depression, Selmi Kallmi
Correlates Of Psychological Well-Being In Older Adults With Treatment-Resistant Depression, Selmi Kallmi
Dissertations
The purpose of this study was to examine the factors that are associated with psychological well-being in older adults with late-life depression and determine if social participation moderates and/or mediates these relationships. This dissertation study utilized secondary pre-treatment data collected from the “Optimum: Optimizing Depression Treatment in Older Adults” study (Cristancho et al. (2019). Community dwelling older adults (N = 369) were included if they currently met criteria for MDD, had failed at least two prior trials of MDD medication treatment, and were able to visit the study site to participate in cognitive and physical functioning assessments. Hierarchical multiple regressions …
Neuroanatomy In Mild Cognitive Impairment: Relationship To Functional Skills, Treatment Expectancy, And Comorbid Depression, Sara Rushia
Dissertations, Theses, and Capstone Projects
Mild cognitive impairment (MCI) is a neurocognitive disorder defined by cognitive decline in older adults. Although MCI has been studied for decades, there remain important areas to be explored in order to adequately characterize aspects of this disorder that provide information valuable for possible interventions and disease progression to dementia, including a better understanding of the neuroanatomical variables relevant to this disorder. Such neuroanatomical variables include cortical thickness, hippocampal volume, and white matter hyperintensities (WMHs). This dissertation consists of three separate studies aimed at addressing gaps in the literature on MCI in relation to brain morphometrics and under-studied characteristics involved …
Does Anxiety Sensitivity Mediate Age-Related Differences In Anxiety In Middle-Aged And Older Adults?, Katherine F. Peterson
Does Anxiety Sensitivity Mediate Age-Related Differences In Anxiety In Middle-Aged And Older Adults?, Katherine F. Peterson
Theses and Dissertations
Anxiety is a mental illness that can have significant deleterious impacts on an individual’s functioning. Although anxiety has been studied in older adults, there is conflicting evidence on differences in anxiety as a function of age. Anxiety sensitivity is a construct that is positively related to anxiety but has limited research in older adults. Extant literature suggests that older adults experience less anxiety sensitivity than do younger adults. According to Socioemotional Selectivity Theory, this may be due to older adults letting go of the things that make them anxious. The current study proposed that age impacts self-rated anxiety such that …
The Coping Strategies Of Older Adults With Age Related Vision Loss (Arvl) – A Narrative Account, Zakara J. Stampp
The Coping Strategies Of Older Adults With Age Related Vision Loss (Arvl) – A Narrative Account, Zakara J. Stampp
Electronic Thesis and Dissertation Repository
The goal of this study was to share the stories of older adults with age-related vision loss (ARVL) and how they have coped to maintain meaningful occupational engagement. Grounded in a constructivist paradigm, data collection and analysis were guided by the narrative inquiry methodology. The participants consisted of six older adults aged 60 or older, diagnosed with one of the following ARVL conditions: macular degeneration, diabetic retinopathy, and/or glaucoma. Participants were recruited from vision loss non-profit organizations such as the Canadian National Institute for the Blind (CNIB) and the Alliance for Equity of Blind Canadians (AEBC). One older adult was …
The Role Of Intimate Partnership Among Older Adults On Pain Severity And The Engagement In Preventative Health Behaviors, Lauren Fox
Doctoral Dissertations
Bodily pain is a frequently disabling condition among older adults, which has broad biopsychosocial implications on health and wellbeing. As adults age, diminishing support systems can result in poor health outcomes and the presence of an intimate partner relationship can positively impact physical health, including influencing pain severity. The number of adults in the United States over 65 is expected to double by 2030, meaning that a significant portion of the population will be entering a stage of increased healthcare utilization. Therefore, behaviors which improve physical health will only become increasingly important over time. While previous research has pointed to …
Quality Of Life And End-Of-Life Plans: The Inclusion Of Sexual Health., Jacinta Dickens
Quality Of Life And End-Of-Life Plans: The Inclusion Of Sexual Health., Jacinta Dickens
Electronic Theses and Dissertations
Sex and intimacy are important components of quality of life (Syme, 2014). Previous research found a positive relation between quality of life and sexual satisfaction (Chao et al., 2011), but how this relation may or may not impact end-of-life plans was unexplored. This study explored if the relation between quality of life and sexual satisfaction determined if community-dwelling middle-aged or older adults in the US have or was willing to incorporate sexual health within their formal or informal end-oflife plan. Correlation analyses examined cross-sectional survey data. Findings revealed a statistically significant correlation between quality of life and sexual satisfaction, no …
Development And Testing Of The Mueller Assessment Of Transition (Mat): A Tool For Measuring Older Adults' Wellbeing When Transitioning Into Assisted Living Facilities, Kaitlin Mueller
All Dissertations
Transitions into assisted living facilities (ALFs) may influence older adults’ wellbeing. Positive influences on older adults’ wellbeing are referred to as adjustment strategies, whereas negative influences are called constraints to wellbeing. Theoretical underpinnings for these influences are found in the Hierarchical Leisure Constraints Theory and the Transition Process Framework. Past research indicates a few influences on older adults’ wellbeing, such as family relationships, perceived physical health, and connections to the community. However, no assessment existed to quantify their wellbeing when relocating into an ALF. Therefore, this dissertation details the development and factor structure of the Mueller Assessment of Transition (MAT), …
Methodological Considerations For The Study Of Cognitive Reserve And Its Relationship To Cognitive Decline In Older Adults, Kerry A. Howard
Methodological Considerations For The Study Of Cognitive Reserve And Its Relationship To Cognitive Decline In Older Adults, Kerry A. Howard
All Dissertations
Cognitive reserve (CR) is a key construct in promoting healthy cognitive aging. Methodological inconsistencies have limited the ability for researchers to make broad conclusions about relevant life experiences that may build CR and delay cognitive decline. This dissertation explored notable issues within the operationalization of CR based on proxy life experiences by applying a systematic approach toward understanding the use of CR, as well as an understanding of consequences of inconsistent operationalization. The project had three aims: review and explore the association between various CR proxies utilized in the literature and develop a composite score for CR, describe differences in …
Put On Your Dancing Shoes: Boosting Divergent Thinking In Older Adults, Megan Itagaki
Put On Your Dancing Shoes: Boosting Divergent Thinking In Older Adults, Megan Itagaki
Scripps Senior Theses
This thesis will explore the influence of two dance modalities (dance improvisation and Zumba dance) on divergent thinking (i.e., an aspect of creativity) in older adults using a quasi-experimental design. Given the existing research on dance as a creativity intervention in the younger half of the population, this study may address a gap in the literature by extending these findings to older adults. Once prescreened to ensure cognitive competence and adequate physical mobility, participants will complete a divergent thinking task before their designated 20-minute dance intervention. After the intervention, participants will complete a divergent thinking task. It is hypothesized that …
Associations Between Self-Reported Awe And Heart Rate, Laura E. Bernstein
Associations Between Self-Reported Awe And Heart Rate, Laura E. Bernstein
Graduate Theses, Dissertations, and Problem Reports
Fredrickson’s (1998, 2013) broaden and build theory states that positive emotions can expand our social and cognitive awareness and provide health benefits. Some positive emotions, such as awe, may operate differently. We sought to understand how subjective reports of awe, induced through videos, correlate with HR. We know that HR tends to decrease with age (Umetani et al., 1998), individuals have less physiological reactivity as they age (Blanchard-Fields, 2007), and older adults report more positive emotions than negative emotions (Mroczek & Kolarz, 1998). Given these findings, we were interested in understanding whether there were age differences in self-reported awe and …
Neural Markers Of Musical Memory In Young And Older Adults, Avital Sternin
Neural Markers Of Musical Memory In Young And Older Adults, Avital Sternin
Electronic Thesis and Dissertation Repository
Memory for music can be preserved in the presence of neurodegenerative disorders even when other memories are forgotten. However, understanding how the brain remembers music has proven difficult despite decades of research. The central goal of this thesis was to elucidate the neural correlates of musical memory by exploring how the presence of language and music information affect the way young and older adults remember music. To that end, I 1) used a controlled training paradigm to familiarize participants with novel stimuli that manipulated the presence of language and music, and 2) collected functional magnetic resonance imaging data to compare …
Personality Pathology And Cognitive Aging: The Role Of Interpersonal Stress, Patrick Joseph Cruitt
Personality Pathology And Cognitive Aging: The Role Of Interpersonal Stress, Patrick Joseph Cruitt
Arts & Sciences Electronic Theses and Dissertations
Research on the relationship between normal-range personality and cognitive aging has demonstrated consistent, but modest, effects. The current investigation seeks to increase our understanding of unhealthy cognitive aging by examining the maladaptive extremes of personality. Borderline and avoidant personality disorder (PD), but not obsessive-compulsive PD, were hypothesized to show prospective associations with cognitive aging. Interpersonal stress was expected to mediate these relationships. The current investigation tested these hypotheses in two longitudinal studies of older adulthood: the Alzheimer’s Disease Research Center cohort (ADRC, N = 434, Mage = 69.95, 56% women) and the St. Louis Personality and Aging Network study (SPAN, …
Examining Intraindividual Variability As A Predictor Of Cognitive And Functional Decline In Older Adulthood, Alyssa N. De Vito
Examining Intraindividual Variability As A Predictor Of Cognitive And Functional Decline In Older Adulthood, Alyssa N. De Vito
LSU Doctoral Dissertations
Intraindividual variability (IIV) has recently emerged as a promising early indicator of future cognitive decline (Haynes et al., 2017). However, the literature is currently limited in that the majority of studies have only examined IIV in one cognitive domain: reaction time. Explorations into the relationship between IIV and functional status are also sparse, with only one recent study exploring this relationship (Schmitter-Edgecombe et al., 2020). The present study aimed to address gaps in the literature by examining IIV in differing cognitive domains to determine which measure(s) were the best predictors of cognitive and functional status at baseline as well as …
Impact Of Aging Information On The Continuing Education Preferences Of Behavioral Health Clinicians, Nicholas Schmidt
Impact Of Aging Information On The Continuing Education Preferences Of Behavioral Health Clinicians, Nicholas Schmidt
Dissertations
The United States population is aging rapidly and the behavioral health workforce is ill-prepared to meet the concurrent rise in demand for services for older adults. Clinicians specializing in working with older adults make up a very small portion of providers and the majority of service provision falls on general practitioners. The discipline of counseling has emphasized multicultural competencies in training and practice but has not specified standards of competence for work with older adults; little is known about the interests and training preferences of Licensed Professional Counselors (LPCs). This study examined the impact of receiving foundational information about aging …
Examining The Mental Health Of Older Hispanic/Latino Adults: Relationship Between Psycho-Social-Cultural Factors And Depressive Symptomatology, Anna Prado
Theses and Dissertations
The most prevalent disorders affecting the older adult population worldwide are dementia and depression. Ethnic minorities are disproportionately more likely to be affected by these two distressing and debilitating conditions. Hispanic/Latino older adults encounter numerous psycho-social-cultural factors that influence health behaviors, attitudes, and beliefs in positive and negative ways. Presently, research on the influence of these factors on Hispanic/Latino mental health is highly inconsistent. The purpose of the present study is to examine the relationship between selected psycho-social-cultural factors and the mental health of older Hispanic/Latino adults. Using data from the Health and Retirement Study, the association between the Hispanic/Latino …
Evaluation Of Telehealth Training To Teach The Stimulus Identification Questionnaire And Multiple Stimulus Without Replacement, Andrea Perez
Evaluation Of Telehealth Training To Teach The Stimulus Identification Questionnaire And Multiple Stimulus Without Replacement, Andrea Perez
Dissertations
The field of behavioral gerontology has seen a paucity in literature within the past 15 years focused on updating training technology and teaching best practice skills to staff. Specifically, there is a need to expand the breadth of training research focus areas could more broadly the elderly population (e.g., increasing engagement), to ensure that trainings are designed to equip caregivers with the skills to be independent, and finally, given the frequent staffing challenges experienced by aging settings (Harrington et al., 2020), to explore effective and efficient training techniques that are alternatives to lengthy, in-person training modalities. Given the personnel challenges, …
Testing The Common-Mechanisms Theory Of False Hearing And False Memory: The Roles Of Executive Functioning And Inhibitory Control, Eric Failes
Arts & Sciences Electronic Theses and Dissertations
Recent studies have shown that older adults are more susceptible to context-based misperceptions in hearing than are younger adults, a phenomenon that has been referred to as false hearing (Rogers et al., 2012; Sommers et al., 2015). The authors of these studies have noted similarities between false hearing and false memories (Jacoby et al., 2005), suggesting that the two phenomena may arise from similar cognitive mechanisms. The present dissertation project investigated similarities between false hearing and false memories. In Experiment 1, I directly compared susceptibility to false hearing and false memories in younger and older adults. I then investigated two …
Exploring The Mechanisms That Underlie The Benefits Of Retrieval Practice In Younger And Older Adults, Ruth A. Shaffer
Exploring The Mechanisms That Underlie The Benefits Of Retrieval Practice In Younger And Older Adults, Ruth A. Shaffer
Arts & Sciences Electronic Theses and Dissertations
The testing effect—or the benefit of retrieval practice to later memory—is often considered to be a recollection-related phenomenon. However, recent work (Shaffer & McDermott, 2020) has observed a benefit of testing to both recollection and familiarity processing on both immediate and delayed final tests. Further, although aging populations show marked declines in recollection, older and younger adults often benefit from testing to a similar degree (Meyer & Logan, 2013). This finding suggests that the testing effect in older adults may function via relatively preserved familiarity and lends further support to the notion that the testing effect does not function solely …
