Aging Intimately, Niamh Mcdonnell, Giulia Hjort

Capstones

We’re both familiar with grief after the loss of family members over 75. This project is our way of giving back in a small way by listening, but also as a way of remembering the people we unexpectedly lost. Each person we’ve met on this journey has inspired us in their own way, with their stories of resilience through grief and aging. All of our collaborators on this project are constantly learning, taking risks, and moving forward through loss and pain. They aren’t defined by their age. Rather, they embrace it with a willingness to reinvent their approach to romance …

Help-Seeking For Cognitive Impairment By The Patient : The Role Of Self-Compassion., Allison J. Midden

Electronic Theses and Dissertations

Older adults represent one of the fastest growing population groups with estimates predicting global growth from 617 million in 2015 to 1.6 billion in 2050. As the aged population increases, incidence of Alzheimer’s disease (AD) and other dementias will also increase. Professionals agree that early intervention is essential for therapeutic and quality of life purposes. However, many older adults wait several months or years to seek medical help after first noticing signs of cognitive impairment. The present study seeks to identify the predictors of help-seeking for cognitive impairment by an individual for him/herself and the role that self-compassion may play …

The Effect Of Viewing Advertisements Depicting Information And Communication Technology On Older Adults' Technology Self-Efficacy, Hollie Brianne Coleman

Masters Theses & Specialist Projects

Information and communication technologies (ICTs) are an important part of society today. Older adults often report ICTs as difficult to use and unhelpful; however, ICTs can support older adults’ ability to stay in touch with family and friends across long distances and help increase their quality of life. Unfortunately, training programs targeted at teaching older adults to use ICTs are often costly and time-consuming. The current study attempts to determine whether advertisements depicting older adults using ICTs can be used to increase self-efficacy without the use of training programs.

A within subjects experimental design was completed using an independent variable …

The Intersection Of Aging And Pet Guardianship: Influences Of Health And Social Support, Ranell L. Mueller, Elizabeth G. Hunter

People and Animals: The International Journal of Research and Practice

Studies of the human-animal bond show many positive health effects for pet guardians including a sense of companionship, reduced depression and loneliness, and higher activity levels, yet few studies have examined factors such as how the pet guardians’ health, age, and social networks influence their relationship with and ability to care for their pet. These health factors may affect the ability of older adults to care for their pets, therefore inhibiting them from reaping positive benefits associated with pet guardianship. This qualitative study involved 21 in-depth interviews with older adults, aged 60+, who were pet guardians. Four themes emerged from …

Thirty-Five Years Of Computerized Cognitive Assessment Of Aging — Where Are We Now?, Avital Sternin, Alistair Burns, Adrian M. Owen

Brain and Mind Institute Researchers' Publications

Over the past 35 years, the proliferation of technology and the advent of the internet have resulted in many reliable and easy to administer batteries for assessing cognitive function. These approaches have great potential for affecting how the health care system monitors and screens for cognitive changes in the aging population. Here, we review these new technologies with a specific emphasis on what they offer over and above traditional ‘paper-and-pencil’ approaches to assessing cognitive function. Key advantages include fully automated administration and scoring, the interpretation of individual scores within the context of thousands of normative data points, the inclusion of …

How Specific Is Domain-Specific Slowing? Evidence For A General Form Of A Domain-Specific Mechanism, Cynthia C. Flores

Arts & Sciences Electronic Theses and Dissertations

Faces are special not just because our ability to quickly and accurately process faces is integral for social functioning throughout our lives, but also because faces are considered a unique class of visual stimuli (i.e., faces rely more on holistic processing than objects and there exist specialized, face-specific regions in the brain). Behavioral and neuropsychological research point to face processing as dissociable from other kinds of visuospatial processing. Although there is evidence that neural specificity for faces is retained in older adults, there is also evidence that age-related impairments are greater in face processing, relative to object processing. Using a …

Dissociable Effects Of Monetary, Liquid, And Social Incentives On Motivation Across The Adult Life Span, Jennifer Crawford

Arts & Sciences Electronic Theses and Dissertations

Humans are social creatures and, as such, can be motivated by aspects of social life, like approval from others, to guide decision-making in everyday life. Indeed, a common view in the aging literature is that older adults have a stronger orientation towards socioemotional goals or incentives, relative to other incentive modalities, like money, because of changing motivational priorities in older adulthood. In prior work, however, we found that older adults actually showed greater effects of monetary relative to primary (liquid) incentives, suggesting alternative interpretations of impaired motivational integration and/or slower adaptation to incentive conditions. The current study tested these alternatives, …

What is the relationship between the cognitive profile and tau imaging correlates for military veterans with moderate to severe TBI …

Home-Based Cognitive Monitoring: The Role Of Personality And Predictors Of Adherence And Satisfaction, Nasreen A. Sadeq

USF Tampa Graduate Theses and Dissertations

Over the last several decades, a growing awareness of the benefits of regular screening for common health conditions, such as cancer and cardiovascular diseases, has paved the way for preventative screenings to become routine in medical settings. Given that cognitive impairment is frequently reported as the number one worry of older adults, home-based cognitive monitoring may be an innovative solution that allows middle aged and older adults to take an active role in monitoring an important aspect of their health. Although several home-based cognitive monitoring programs have been validated for use in clinical and home-based settings, the Cogstate Brief Battery …

Examining The Effects Of Stress And Age On Neural Reward Processing: Considerations For The Role Of Individual Differences In Autonomic Reactivity, William Mccuddy

Dissertations (1934 -)

Acute stress is unavoidable and may hinder basic reward processing underlying adaptive decision-making. Additionally, older adults may be at an increased risk of poor decision-making after exposure to acute stress due to age-related changes in cognitive and autonomic functioning. The current study assessed the influence of acute stress, autonomic reactivity, and age on a simple behavioral task during fMRI. Specifically, old and young adults completed a basic reward processing paradigm (i.e., where participants received monetary rewards and punishments) after exposure to acute stress (i.e., social evaluative cold pressor) or control procedure between-subjects. In the young group, differential responses for monetary …

Socioeconomically Disadvantaged Neighborhoods, Stroke Risk, And Cognition In Older Adults: A Focus On Violent Crime, Linda D. Ruiz

College of Science and Health Theses and Dissertations

Living in socioeconomically disadvantaged neighborhoods, i.e., neighborhoods with lower incomes, lower education/occupational levels, and/or higher crime, increases one’s risk of developing chronic health problems, including cardiovascular disease risk factors and stroke. These health problems are associated with reduced cognition and dementia and may help to explain disparities in brain aging. We investigated the association of neighborhood socioeconomic characteristics on stroke risk and cognitive outcomes hypothesizing that stroke risk mediates the association between the socioeconomic environment and cognitive functioning. Participants were non-demented community-dwelling older adults (N=121), ~67 years of age (50% male, 44% non-Latino Black) who underwent cognitive and medical assessments. …

The Revelation Effect In Autobiographical Memory, Vincent A. Medina

Seton Hall University Dissertations and Theses (ETDs)

The revelation effect is a memory illusion in recognition memory where items are more likely to be considered old if they are immediately preceded by a cognitive task (for a review, see Abfalg, Bernstein, & Hockley, 2017). Recent research has shown that the revelation effect appears in past and future episodic judgments so long as the tasks are autobiographical in nature (Westerman, Miller, & Lloyd, 2017). Aging is a factor that has not yet been studied in the revelation effect literature in terms of autobiographical memory. It has implications because of aging’s significant impact on mental time travel. During this …

Exploring Age-Related Metamemory Differences Using Modified Brier Scores And Hierarchical Clustering, Chelsea Parlett

Computational and Data Sciences (MS) Theses

Older adults (OAs) typically experience memory failures as they age. However, with some exceptions, studies of OAs’ ability to assess their own memory functions– Metamemory (MM)– find little evidence that this function is susceptible to age-related decline. Our study examines OAs’ and young adults’ (YAs) MM performance and strategy use. Groups of YAs (N = 138) and OAs (N = 79) performed a MM task that required participants to place bets on how likely they were to remember words in a list. Our analytical approach includes hierarchical clustering, and we introduce a new measure of MM—the modified Brier—in order to …

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 …

Do Private Household Transfers To The Elderly Respond To Public Pension Benefits? Evidence From Rural China, Plamen Nikolov, Alan Adelman

Economics Faculty Scholarship

Aging populations in developing countries have spurred the introduction of public pension programs to preserve the standard of living for the elderly. The often-overlooked mechanism of intergenerational transfers, however, can dampen these intended policy effects, as adult children who make income contributions to their parents could adjust their behavior in response to changes in their parents’ income. Exploiting a unique policy intervention in China, we examine using a difference-in-difference-in-differences (DDD) approach how a new pension program impacts inter vivos transfers. We show that pension benefits lower the propensity of adult children to transfer income to elderly parents in the context …

The Influence Of Aging, Gaze Direction, And Context On Emotion Discrimination Performance, Alyssa Renee Minton

Masters Theses & Specialist Projects

This study examined how younger and older adults differ in their ability to discriminate between pairs of emotions of varying degrees of similarity when presented with an averted or direct gaze in either a neutral, congruent, or incongruent emotional context. For Task 1, participants were presented with three blocks of emotion pairs (i.e., anger/disgust, sadness/disgust, and fear/disgust) and were asked to indicate which emotion was being expressed. The actors’ gaze direction was manipulated such that emotional facial expressions were depicted with a direct gaze or an averted gaze. For Task 2, the same stimuli were placed into emotional contexts (e.g., …

The Influence Of Stressful Life Events On The Development Of Type 2 Diabetes, Joshua Minks

Dissertations

This study examined the relationship between distress and the development of Type 2 diabetes mellitus (T2DM) in the presence of established risk factors. Distress secondary to mental health disparities, stressful life events, and work conditions has been shown to promote insulin resistance and the development of T2DM.

Subjects (N=79) diagnosed with T2DM within the previous six months were recruited from SSM Health Centers and VA Medical Centers in the greater St. Louis area. They completed the Recent Life Changes Questionnaire, ENRICHD Social Support Instrument, and a demographic survey and analyses were conducted to determine differences between the veteran …

Moderating Effect Of Cortical Thickness On Bold Signal Variability Age-Related Changes, Daiana R. Pur, Roy A. Eagleson, Anik De Ribaupierre, Nathalie Mella, Sandrine De Ribaupierre

Brain and Mind Institute Researchers' Publications

© Copyright © 2019 Pur, Eagleson, de Ribaupierre, Mella and de Ribaupierre. The time course of neuroanatomical structural and functional measures across the lifespan is commonly reported in association with aging. Blood oxygen-level dependent signal variability, estimated using the standard deviation of the signal, or “BOLDSD,” is an emerging metric of variability in neural processing, and has been shown to be positively correlated with cognitive flexibility. Generally, BOLDSD is reported to decrease with aging, and is thought to reflect age-related cognitive decline. Additionally, it is well established that normative aging is associated with structural changes in brain regions, and that …

That Note Sounds Wrong! Age-Related Effects In Processing Of Musical Expectation, Andrea R. Halpern, Ioanna Zioga, Martin Shankleman, Job Lindsen, Marcus T. Pearce, Joydeep Bhattacharya

Andrea Halpern

Part of musical understanding and enjoyment stems from the ability to accurately predict what note (or one of a small set of notes) is likely to follow after hearing the first part of a melody. Selective violation of expectations can add to aesthetic response but radical or frequent violations are likely to be disliked or not comprehended. In this study we investigated whether a lifetime of exposure to music among untrained older adults would enhance their reaction to unexpected endings of unfamiliar melodies. Older and younger adults listened to melodies that had expected or unexpected ending notes, according to Western …

Absolute Pitch In Naturalistic Singing: A Commentary On Olthof Et Al., Andrea R. Halpern

Andrea Halpern

The parent article looks at pitch stability in an archive of folksongs recorded over several decades. Some evidence for pitch stability was found. Here, I consider some additional aspects of the archive that could be examined, offer some extensions to relevant laboratory studies, and consider some inherent strengths and limitations of the naturalistic, archival approach.

An Investigation Into The Impact Of Acute Stress On Encoding In Older Adults, Amy M. Smith, Katinka Dijkstra, Leamarie Gordon, L. Michael Romero, Ayanna K. Thomas

Psychology Department Faculty Works

Acute psychological stress commonly occurs in young and older adults’ lives. Though several studies have examined the influence of stress on how young adults learn new information, the present study is the first to directly examine these effects in older adults. Fifty older adults (M age = 71.9) were subjected to either stress induction or a control task before learning two types of information: a short video and a series of pictures. Twenty-four hours later, they were exposed to misleading information about the video and then completed memory tests for the video and pictures. Heart rate and cortisol measures …

Arousal Or Relevance? Applying A Discrete Emotion Perspective To Aging And Affect Regulation, Sara E. Lautzenhiser

ETD Archive

While research in the psychology of human aging suggests that older adults are quite adept at managing negative affect, emotion regulation efficacy may depend on the discrete emotion elicited. For instance, prior research suggests older adults are more effective at dealing with emotional states that are more age-relevant/useful and lower in intensity (i.e., sadness) relative to less relevant/useful or more intense (i.e., anger). The goal of the present study was to probe this discrete emotions perspective further by addressing the relevance/intensity distinction within a broader set of negative affective states (i.e., fear and disgust, along with anger and sadness). Results …

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) …

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 …

Age-Related Differences In Cognition And Affect At Work : The Impact Of Mindfulness, Sara Michelle Stevens

Legacy Theses & Dissertations (2009 - 2024)

The present research examined job-related affective and cognitive processes across ages, and the role of trait mindfulness as a mechanism that influences the strength of these relationships. Specifically, job-related affective well-being, job satisfaction, and fluid intelligence were investigated as they relate to dynamics of aging. Participants on Amazon’s Mechanical Turk (N = 174) completed a two-time longitudinal survey separating individual difference tests of trait mindfulness and fluid intelligence at Time 1 from self-report assessments of job satisfaction and job-related affective well-being at Time 2. Overall, the results from this study provide strong evidence that age and mindfulness both play an …

Manipulating Belief Bias Across The Lifespan, William D. Carney

Williams Honors College, Honors Research Projects

In today’s political climate, when basic facts and reasoning are seemingly up for debate, it is increasingly important to be able to identify well-reasoned arguments, regardless of one’s political leanings, and to retain this skill throughout the lifespan. Research has shown, however, a persistent belief bias—a tendency to judge an argument’s validity based on its conclusion’s agreement with one’s beliefs, rather than its logical quality. Other findings suggest that belief bias can be reduced by instruction to avoid belief bias. The current project seeks to explore whether older adults, believed to be more prone to biased reasoning, respond differently to …

Generational Perceptions Of Support Among Congolese Refugees In Urban Tanzania, Julie A. Tippens

Department of Child, Youth, and Family Studies: Faculty Publications

Urban refugees frequently fall outside of the scope of humanitarian assistance programs. Despite a growing body of research describing the experiences of urban refugees in low- and middle-income countries (LMICs) of first asylum, little is known about generational differences in perceived support in these contexts. This phenomenological study used in-depth, semi-structured interviews and small group discussions to identify sources and meanings of support among older adult (50+; n= 23) and younger adult (18–30; n= 11) Congolese refugees in Dar es Salaam, Tanzania. Family and fictive kin emerged as central sources of support across age groups. However, instrumental support was sought …

Implicit Attitudes Of Asian American Older Adults Toward Aging, Anita Ho

Scripps Senior Theses

Greenwald, McGhee, and Schwartz (1998) developed the Implicit Association Test (IAT), a measure of mental associations between target pairs and positive or negative attributes. Highly associative categories yield faster responses than the reverse mental associations, which is thought to reflect implicit attitudes toward stereotypes. The present study investigated the effect of ethnic group on one’s implicit attitudes toward aging and gender stereotypes by comparing two groups of older adults, Asian Americans and Caucasian Americans, that likely hold different culture values. Past qualitative studies have established the existence of mental health stigma in Asian American populations, including negative Asian American perceptions …

Longitudinal Associations Between Functional Disability, Depression, And Suicide In Middle-Aged And Older Adults, Julie Ann Lutz

Graduate Theses, Dissertations, and Problem Reports

Suicide is a significant public health problem among older adults in the United States and around the world. There has been little research to date on longitudinal change in functional disability and depressive symptoms, both of which have been posited to be associated with suicide risk among middle-aged and older adults, and their association with death by suicide. The aims of this study were to 1) characterize longitudinal change in functional disability and depressive symptoms separately; 2) characterize the directional associations between functional disability and depressive symptoms in bivariate models; and 3) determine how different patterns of change among these …
