Psychometric Analyses Of A Comprehensive Neuropsychological Battery For Retired Nfl Players, Kimberly Ethridge Fitzgibbon

Theses and Dissertations

This study examined psychometric properties of the NFL Concussion Battery used to examine neuropsychological functioning in retired NFL players who were part of the NFL’s concussion settlement. This battery assesses multiple areas of cognitive functioning; executive functioning, language, processing speed, attention and memory. The study included 117 participants who were male with at least 16 years of education. The sample was 75.9% African-American and average age was 47. All participants completed the entire battery and passed the majority of effort measures. Those that did not pass the majority of effort measures or complete the entire battery were excluded.

The Effects Of Sleep Restriction On Biological, Psychological, And Neurocognitive Measures Of Health, Margaret S. Lorenzetti

Theses and Dissertations

Chronic sleep restriction impacts a significant proportion of the population, even though health is optimized following a minimum of seven hours of sleep. A preponderance of the literature examining the effects of sleep loss focuses on males and total sleep deprivation. Sleep restriction paradigms provide more ecological validity, as they are more consistent with sleep loss characterized in epidemiological studies. Moreover, enhancing the understanding of sleep loss among women, who are generally the gender most likely to encounter negative health as a result of poor sleep quality, is crucial. Thus, this investigation aimed to examine sleep restriction amongst a female …

Breaking Away: The Role Of Homeostatic Drive In Perpetuating Depression, Jonathan Tory Toole

Theses and Dissertations

The brain can be considered a complicated system of feedback mechanisms that maintain physiological homeostasis. Through psychological activity, neurochemicals act as homeostatic regulators. This study proposes that these components are part of a regulatory system that is capable of supporting multiple homeostatic regimes that, in turn, give rise to self-sustaining psychological behaviors. This project hypothesizes that such alternate regulatory programs may play a role in perpetuating psychological dysfunction. Interactions within and between components of the neurotransmitter network are represented as a set of discrete logic circuits. Neurotransmitter levels are linked to psychological constructs such as depression based on current literature. …
