The Relationship Between Depression And Cognitive Proficiency Index Across Biological Sex, Angela N. Ferdinardo

Dissertations

Depression is a widely studied mood disorder, and understanding its effect on cognitive functioning has become an important area of research. While research has examined relationships among depression, working memory, and cognitive deficits, limited research has explored depressive symptoms and cognitive proficiency across biological sex. Depression manifests similarly in men and women, though men are more likely to experience irritability, impulsivity, and anger, while women tend to experience sadness, stress, and sleep disturbances (Johns Hopkins Medicine, 2023). Women are also more likely to seek treatment and cope differently than men. This study examined the relationship between depression and cognitive proficiency …

From Stranger To Self: The Role Of Familiarity In Modulating The N170 And N250 Erp Components, Tabish Gul

Dissertations

This study investigated how varying levels of face familiarity modulate the N170 and N250 event-related potential (ERP) components, two neural markers of face perception and recognition. While the N250 is widely considered familiarity-sensitive, the N170 has traditionally been linked to the structural encoding stage of face perception. However, recent research suggests that face familiarity may also influence N170 amplitude and latency. While most previous studies have compared up to three familiarity levels, the present study examined five levels of familiarity: own face, friend’s face, famous face, experimentally familiar face, and unfamiliar face. Twenty-six participants viewed face images while completing a …

Utility Of The Motivation To Change Lifestyle And Health Behaviors For Dementia Risk Reduction Scale (Mclhb-Drr) Based On A North American Sample, Angelina E. Witbeck

Dissertations

As the population ages, the prevalence rates of dementia continue to increase. Without a cure or promising treatment for dementia, the best course of lowering the prevalence rates of dementia is through preventative measures. Through an electronic survey, the study utilized the MCLHB-DRR scale to determine whether (1) gender, age, educational background, and socioeconomic status will impact the motivational factors to change lifestyle and health behaviors to reduce the risk of developing dementia and (2) direct experiences with individuals that have a dementia diagnosis are likely to impact one's motivational factors to change lifestyle and health behaviors to reduce the …

Life Satisfaction: Aging Female Informal Caregivers Of Persons With Dementia, Deborah Ann Monson

Dissertations

Purpose/Aims

The purpose of this study was to describe the relationship between aging female informal caregivers of persons with dementia (PWD) and care recipients’ PWD demographic factors, aging female informal caregivers of PWD social support factors, positive and negative feelings, a sense of flourishing, stress, and life satisfaction.

Background/Rationale

Older adults with dementia are living longer and the majority are receiving care by aging female informal caregivers. Dementia incrementally worsens over time impacting informal caregiver life satisfaction. Most studies have focused on negative aspects of informal caregiving. Therefore, this study investigated both positive and negative aspects of caregiving.

Confabulation In Individuals With Disorders Of The Corpus Callosum: Educational Implications, Cheryl Lynn Wright

Dissertations

Individuals with disorders of the corpus callosum (DCC) may have subtle cognitive differences. Historically, confabulation has been associated with DCC. Therapies to mitigate confabulation is a newly emerging field. This study explores the possible educational implications that those with DCC may experience with confabulation.

The community of people with DCC and the community of people who interact with individuals with DCC were surveyed to ascertain the prevalence of confabulation within the population of those with DCC. A subset of questions probed whether age and/or gender impact the rates of reported confabulation. The research paradigm included a section that covered the …
