The Effects Of Physical Function And Genetics On Cognition And Blood Biomarkers In Individuals At-Risk For Alzheimer’S Disease And Related Dementias, Joshua Louis Gills

Graduate Theses and Dissertations

Alzheimer’s disease and related dementia (ADRD) rates are expected to triple by the year 2050. Early detection and specific mitigation efforts are warranted to blunt the alarming rate. Physical function (PF) declines with age, but higher physical function is associated with better cognitive functioning in middle-to- older age individuals. Moreover, greater physical activity (PA) is associated with better global cognition; however, Apoliporotein e4 carriers may not gain the same benefits with exercise. Additionally, plasma phosphorylated tau 217 (p-tau217) has been identified as a novel diagnostic ADRD biomarker which needs further research to examine associations with risk factors. Therefore, the aims …

Negative Urgency's Influence On State-Level, Emotion-Based Changes In Alcohol-Related Cognitions, Noah Wolkowicz

Graduate Theses and Dissertations

This project expanded on the Acquired Preparedness Model of Risk (APMR) by examining how Negative Urgency (NU), the tendency to act rashly in negative emotional states, affects emotion-based changes in alcohol cognitions to produce risk for alcohol use. The APMR prioritizes the role of outcome expectancies as the means through which traits such as NU, convey alcohol use risk. However, this model treats these cognitions as static and often fails to assess their valence; further, alcohol-cognitions fluctuate in response to negative emotions and may become more salient during these states. Therefore, this study examined: 1) how NU impacts negative emotion-based, …

Facts From Fiction: Packaging Misinformation, Angel Ray Houts

Graduate Theses and Dissertations

Previous research established that readers learn both accurate and inaccurate information from fictional stories. The current study explored factors that might moderate the impact of misinformation. Participants read fictional stories that contain three assertions; the first two were labeled as set-up assertions, and the last were labeled as the critical assertion. First, there was a manipulation of plausibility of information within the stories by presenting either assertions with truthful information, assertions with small lies (plausible misinformation), or assertions with big lies (implausible misinformation). Second, there was manipulation of reliability of the fictional stories by presenting big lies or truthful information …

Validity And Reliability Of A 5-Minute Web-Camera Based Eye Tracking Test To Assess Visual Memory And Cognition, Emily Bates

Graduate Theses and Dissertations

There are approximately 5.7 million Americans currently living with Alzheimer’s Disease (AD). Early detection of cognitive impairment allows for earlier treatment, potentially slowing or halting cognitive decline. A 30-min web-camera eye tracking assessment (30-min VPC) has been validated as a tool to predict AD risk. However, a shorter version would allow for greater scalability and improve user experience. The purpose of this study was to: 1) determine the validity of the 5-minute web-camera based VPC test with the 30-min test, 2) determine the test-retest reliability of the 5-min test, 3) compare the 5-minute test scores of cognitively intact adults (18-39 …

The Effects Of Consuming Eggs On The Physical And Cognitive Development Of Food-Insecure Haitian Children, Monica Elaine Stewart

Graduate Theses and Dissertations

Within Latin America and the Caribbean, severe food insecurity is highest in Haiti. Fifty-five percent of the population lives below the poverty line with approximately 50% of the population undernourished. Given the typical diet in the developing world is primarily plant-based, the two studies presented in this thesis examine how eggs, a locally available animal protein, impact physical growth, cognitive development, and motor skills of food-insecure children from a single orphanage in Leogane, Haiti when added to the diet.

In the first study, growth parameters in children ages 3-8 years old were measured at baseline, six months, and one year. …

The Effects Of Hypohydration On Neurocognitive, Balance, Vestibular Ocular Motor Functions And Mood State, Satoshi Iida

Graduate Theses and Dissertations

Inconsistent findings have been observed on the impact of hydration state on cognitive functions. The isolated effect of hypohydration on neurocognitive performance, balance, vestibular ocular motor function and mood outcomes in widely used concussion assessment tools has not been studied. The purpose of this study was to investigate how hypohydration affected the results in concussion testing batteries. A single-blind randomized crossover design was used. Thirteen healthy males (22 ± 4y, 180.9 ± 5.7cm) without history of concussion within the past six months or any condition or disease that could influence outcome measurements participated in this study. Each subject completed concussion …

Disentangling Embodied Cognition: An Examination Of The State, Problems, And Possibilities Of Embodied Cognition, Cody Cash

Graduate Theses and Dissertations

Embodied cognition has received a fair amount of attention in philosophical, neuroscientific, and robotic research during the past several decades, yet the precise nature of its goals, methods, and claims are unclear. This dissertation will ascertain and examine the primary themes in the field of embodied cognition as well as why, and if, they offer significant challenges to traditional cognitive science models. Though many theories believe they are providing accounts that should replace traditional models, to do so they will have to overcome the very difficult challenge of arguing that mental content and capabilities derived from sensorimotor activity can continue …

Is The Geriatric Impact Ipad Test A Valid Measurement Of Cognitive Function In Older Adults?, Heather Elise O'Dell

Graduate Theses and Dissertations

The number of older adults will rapidly increase within the next generation (Brookmeyer, Johnson, Ziegler-Graham, & Arrighi, 2007). Alzheimer’s disease risk increases with age, especially after age 60 (NIA, n.d.). Aging leads to a decrease in functional independence, and this side effect is exacerbated by cognitive decline (Johnson, Lui, & Yaffe, 2007). Executive function is a predictor of Alzheimer’s disease onset and progression (Zhang, Han, Verhaeghen, & Nilsson, 2007). The Geriatric ImPACTTM test is a potential new and more convenient testing methods than traditional methods used. The purpose of this research is to validate the Geriatric ImPACTTM test by comparing …

A Manipulation Of Cognitive Restriction And Goal-Conflict: Mechanisms Underlying The Disinhibition Effect Of Eating Behavior, Kayla D. Skinner

Graduate Theses and Dissertations

People are often faced with a self-control dilemma whenever the attainment of a long-term goal would come at the expense of an alluring temptation. The goal-conflict model of eating (Stroebe, van Koningsbruggen, Papies, & Aarts, 2013) suggests that restrained eaters (i.e., chronic dieters) experience self-regulation failure (e.g., overeating, or disinhibition) due to inner competing goals of eating enjoyment and weight control. The current study examined these concepts in a sample of people classified as unrestrained eaters (N = 123), allowing for an investigation of restricted cognitive focus as a causal mechanism of disinhibited eating. A 2 (restraint condition: restriction, intuitive …

The Effect Of Music Training On Emotion Perception In Childhood, Emese Maroti

Graduate Theses and Dissertations

Numerous studies found evidence that music training can enhance cognitive abilities both for children and adults. However, no evidence was found yet, whether music training can enhance abilities in emotion perception. I tested 8-9 year-old children on emotion perception in visual and musical contexts. The tests did not show significant difference between the musically trained and non-trained group neither in visual nor in musical context, however, when emotion scores were analyzed separately for each piece of music, musically trained children's responses reflected stereotypical modes of approaching emotional meanings in music, moreover, musically trained children's judgments were more uniform as there …
