Causes And Consequences Of The Risk Of Generalizability Biases In Health Behavioral Interventions, Lauren Von Klinggraeff

Theses and Dissertations

Preliminary testing of health behavior interventions (e.g., pilot, feasibility studies) are used to evaluate intervention viability prior to additional testing and resource investment (e.g., larger trials). This initial testing provides valuable information, but promising estimates of effectiveness produced during early testing are rarely reproduced in larger studies, stalling the development of effective, scalable health interventions. In the obesity intervention literature, external validity biases, features of the intervention that are not (or cannot) transfer to the larger study, are associated with these diminished effects. These study features, such who delivers the intervention, the characteristics of the population receiving the intervention or …

Predictors Of Driving Performance Post-Stroke, Halle Elise Prine

Theses and Dissertations

Driving is a complex skill involving the interaction of various brain functions, making it challenging to determine the independent contributions of each process to driving proficiency. While past studies have identified assessments such as the Useful Field of View Test (UFOV) and the Trial Making Test (TMT) as strong predictors for driving skills, little research has explored the impact of visual search and movement inhibition on driving after stroke. This cross-sectional study includes participants between the ages of 21 to 80 years with residual disability caused by a unilateral middle cerebral artery stroke at least six months prior. The participants …

Effects Of Positive Social Comparative Feedback During Practice On Motor Sequence Learning, Performance Expectancies, And Resting State Connectivity, Allison Foster Lewis

Theses and Dissertations

Positive social comparative feedback indicates to the learner that they are performing better than others. While this type feedback supports motor skill learning in some tasks, the effect of social comparative feedback on motor sequence learning remains unknown. In addition, the OPTIMAL theory predicts that positive social comparative feedback may trigger a dopaminergic response in the brain. However, no studies have utilized neuroimaging techniques to investigate this question. Therefore, the aim of these studies was to determine the effect of positive social comparative feedback on motor sequence learning, performance expectancies, and resting state connectivity of dopaminergic neural pathways.

Impact Of A Novel Marine Algae Supplement On Inflammatory And Immune Response After High-Intensity Exercise, Caroline Sara Vincenty

Theses and Dissertations

INTRODUCTION: High-intensity exercise (HIE) can damage the musculotendon complex and impact the immune response, which may result in post-exercise inflammation and reductions in strength and performance. Sufficient rest and recovery will improve muscular resilience against future damaging bouts, however HIE with minimal durations of rest are common in athletic competitions that facilitate persistent inflammation and immune dysregulation. Marine algae-derived fucoidans (MA) have previously shown promise to mitigate pro-inflammatory and immune dysregulation responses, however it has not been investigated in the context of HIE. The purpose of this research is to investigate the safety and efficacy of MA on markers of …

Relationships Among Sleep, Physical Activity, And Weight Status In Children And Adolescents, Agnes Bucko

Theses and Dissertations

Sleep and physical activity are both associated with multiple behavioral and metabolic health outcomes, and both behaviors have been linked to the development of weight status. Recent estimates suggest that many children are not meeting sleep recommendations or participating in adequate levels of physical activity, which may be related to the high prevalence of childhood overweight and obesity. Much of the research assessing these relationships has focused on adults and older children, and has relied on parent- or child-reported, cross-sectional research in predominantly White samples. Little work has focused on these relationships in very young children. Although more research has …

Using A Multi-Direction Reaching Approach To Investigate Fitts’ Law And The Effect Of Attentional Focus On Motor Learning, Charles R. Smith

Theses and Dissertations

The Index of Difficulty value (ID) derived from Fitts’ Law’s speed-accuracy trade-off is commonly used to determine the difficulty of a targeted reaching movement and balance difficulty in sequence learning tasks. However, this value does not account for the mechanical difficulty of multi-directional movements which could affect both performance and learning. Where we direct our focus when completing a task/skill can also have an effect on how we perform and learn that task, however, the manner in which differing focus instructions affect learning a whole-arm reaching task is relatively unknown. The purpose of this dissertation was to examine 1) how …

Psychophysiological Biomarkers Of Concussion Recovery, Adam Todd Harrison

Theses and Dissertations

Each ach year a growing number of individuals report lingering deficits months-years following concussion. Persistent post-concussion symptoms (PPCS) can negatively impact day-today activities and if left untreated may manifest in severe neurological sequelae resulting in long-term cognitive impairment or advanced neurological degeneration (i.e., CTE). Current clinical diagnostic and prognostic assessments (e.g., symptom reports and neurocognitive testing) lack the sensitivity to quantify neurological function. Accordingly, there is a critical need to identify objective biomarkers specific to PPCS to improve an individual’s quality of life and prevent severe long-term neurological dysfunction.

Psychophysiological measurements (e.g., EEG derived event-related potentials, heart rate variability, and …
