Measuring Referential Communication Dynamically In Older Children With Asd, Caitlin Lee

Masters Theses, 2020-current

Research finds individuals with autism spectrum disorder (ASD) are relatively ineffective and/or inefficient at referential communication. However, this research typically uses static metrics of efficacy (how accurately messages were relayed) and efficiency (overall word count), rather than dynamic ones (e.g., Does the speaker alter subsequent descriptions when the listener previously misunderstood them?). The aim of this research is to use dynamic measures of efficacy and efficiency to examine how speakers with and without ASD adjust their message to meet listener needs across time. Fifteen older children with (n = 8) and without (n = 7) ASD were included. …

Like, It’S Important: The Frequency And Use Of Like In Autism Spectrum Disorder, Rebekah Jones

Masters Theses, 2020-current

Background & Aims: Discourse markers, such as well or like serve a variety of functions to support conversational reciprocity: filling pauses, aiding word-finding, holding conversational turns, and providing information about pause length. Previous research shows that individuals with ASD use discourse markers less frequently than neurotypical (NT) peers; however, the discourse marker like has been left out of that research, despite its ubiquitous use by NT individuals, and despite the fact that like serves important pragmatic functions that are not encoded by any other discourse marker. Specifically, like signals to the listener that the content of upcoming speech is 1) …

The Effects Of A Carbohydrate Hydrogel Beverage On Gastrointestinal Symptoms And Running Performance In Comparison To Conventional Carbohydrate Beverages, Nicholas Minichiello

Masters Theses, 2020-current

PURPOSE: The utilization of hydrogel technology allows carbohydrate beverages to form a gel in the acidic environment of the stomach, potentially enhancing gastric emptying. However, few studies have researched the effects of these beverages on gastrointestinal (GI) tolerance and exercise performance; there is minimal data in a variety of exercise conditions and/or beverage ingestion rates. The purpose of the present study was to assess the effects of a 80 g/h of maltodextrin-fructose hydrogel (MF-H) beverage versus conventional carbohydrate sources on GI symptoms and running performance. METHODS: eight distance runners (26 ± 5 y; VO_2max = 65 ± 7 ml/kg/min) …

Responses To Partner Comments And Acknowledgements In Students With And Without Autism, Kaitlyn Bresette

Masters Theses, 2020-current

Some children and adolescents with Autism Spectrum Disorder (ASD) initiate and respond less frequently than neurotypicals (NT) during language sampling tasks. More information is needed regarding how partner behaviors, such as comments and acknowledgements and the sampling context, influence the types of responses provided by children with ASD. This research study examined responses to adult comments and acknowledgments in two language sampling tasks, a traditional Share and Tell sample and a Double Interview sample (Garcia-Winner, 2002).

Participants. Fifty-eight participants, between the ages of 10 and 17 years, were recruited across two labs. The sample consisted of 28 adolescents with ASD …

Identifying The Molecular Pathways That Drive Retinal Degeneration In The Childhood Neurodegenerative Disease: Mucolipidosis Type Iv, Michael Pamonag

Masters Theses, 2020-current

Humans, like many other vertebrates, possess five Aristotelian senses (vision, olfaction, hearing, taste, and touch) which we use to experience and navigate our environment. Our visual system is the only source of light detection and light signaling in our bodies. This makes our visual system essential for detecting movement, distance, time of day, and seasonal changes in the length of days within our environment. The visual systems of most animals are designed to capture photons of visible light and convert that energy into a neurological signal (visual signal) to be transmitted to brain regions responsible for visual perception1 . This …

Therapeutic Potential Of A Ketogenic Diet In The Treatment Of Major Depressive Disorder, Jordan A. Murrin

Masters Theses, 2020-current

Major depressive disorder (MDD) is the second most common mental health condition and a leading cause of disability in the world. It is theorized that MDD develops from a combination of biological, psychological, and social stressors. The condition is typically treated using pharmaceuticals and psychotherapy. However, not all individuals with MDD have access to or choose to use these treatments, or may prefer to incorporate therapeutic lifestyle changes such as exercise, sleep, and healthy eating. Even with treatment, MDD can alter brain structure and function, leading to the development of comorbid mental health and chronic metabolic conditions like obesity, cardiovascular …

Return To School 1 Year After Traumatic Brain Injury: A Study Using The Traumatic Brain Injury Model Systems National Database, Kathryn Tarnai

Masters Theses, 2020-current

For many individuals, recovery from moderate to severe brain injuries involves returning to a level of pre-injury productivity. Specifically, previous research has focused extensively on factors predicting return to employment, where students are inconsistently categorized with those in competitive employment. Moreover, research dedicated to return to school for students in secondary and tertiary education is largely qualitative; very few studies have utilized predictive modeling on a sample composed solely of students. For this study, a model including days of post-traumatic amnesia (PTA), length of stay (LOS), rehabilitation discharge Disability Rating Scale (DRS) scores, and educational level was used to predict …

Impact Of 12-Weeks Of Nordic Pole Walking On Arterial Stiffness In Sedentary Overweight And Obese Adults, Arbër N. Shehu

Masters Theses, 2020-current

Arterial stiffness (AS) is an independent predictor for cardiovascular disease morbidity and mortality. Regular aerobic exercise is considered to improve AS. Nordic walking provides important health benefits, however, the effect of this walking method as treatment for AS remains unclear. We conducted a randomized controlled study to examine the effect of a 12-week supervised group walking intervention (controlled pace, ~3000 steps/day, 30 minutes/day, 5 times/week), with (NW) and without (SW) Nordic poles, on AS in sedentary overweight and obese adults.

Lipoprotein Associated Phospholipase A2 In Individuals With Obstructive Sleep Apnea, Kendall G. Clark

Masters Theses, 2020-current

Abstract

Introduction: Lipoprotein-associated Phospholipase A₂ (Lp-PLA₂) is a protein produced by inflammatory cells in circulation and is associated with cardiovascular disease (CVD) risk. Prior research demonstrates that obstructive sleep apnea (OSA) leads to increased inflammation and is also related to CVD. Physical activity is known to reduce inflammation and risk for both CVD and OSA. However, Lp-PLA₂ has yet to be examined in individuals with OSA who do not have any other pre-existing conditions nor has it been associated with chronic physical activity. The purpose of this study was to examine if there is a relationship …

Microglia And Fractalkine Involvement In Shaping Multimodal Midbrain Circuitry, Cooper A. Brett

Masters Theses, 2020-current

Microglial cells (MGCs) are highly dynamic and have been implicated in shaping discrete neural maps in several systems. MGCs respond to numerous cues in their microenvironment, including a neuronally-expressed chemokine, CX3CL1 (fractalkine). The present study examines microglial and CX3CL1 patterns with regard to the emerging modular-extramodular framework within the lateral cortex of the inferior colliculus (LCIC). The LCIC is a shell region of the auditory midbrain where discrete compartments receive modality-specific connections, whereby somatosensory inputs terminate within modules and auditory inputs target surrounding extramodular zones. A reliable modular marker, glutamic acid decarboxylase (GAD), enables visualization of emerging modular domains in …
