Neuroanatomy In Mild Cognitive Impairment: Relationship To Functional Skills, Treatment Expectancy, And Comorbid Depression, Sara Rushia Sep 2022

Neuroanatomy In Mild Cognitive Impairment: Relationship To Functional Skills, Treatment Expectancy, And Comorbid Depression, Sara Rushia

Dissertations, Theses, and Capstone Projects

Mild cognitive impairment (MCI) is a neurocognitive disorder defined by cognitive decline in older adults. Although MCI has been studied for decades, there remain important areas to be explored in order to adequately characterize aspects of this disorder that provide information valuable for possible interventions and disease progression to dementia, including a better understanding of the neuroanatomical variables relevant to this disorder. Such neuroanatomical variables include cortical thickness, hippocampal volume, and white matter hyperintensities (WMHs). This dissertation consists of three separate studies aimed at addressing gaps in the literature on MCI in relation to brain morphometrics and under-studied characteristics involved …


Pilot Study Of The Effects Of Mobile Based Resonant Frequency Breathing On Cognitive Performance In Healthy Young Adults With Elevated Stress, Daniel Saldana Sep 2021

Pilot Study Of The Effects Of Mobile Based Resonant Frequency Breathing On Cognitive Performance In Healthy Young Adults With Elevated Stress, Daniel Saldana

Dissertations, Theses, and Capstone Projects

Objective: Prior research has shown a bidirectional relationship between breathing, emotions, behavior, and cognitive functions thought to be mediated by the autonomic nervous system (ANS). Studies have shown that deep or diaphragmatic breathing interventions are associated with improved affect and decreased stress levels, but little attention has been paid to the effects of breathing training on cognition. The few studies that have looked at this have shown improved attention, memory, and executive functioning as a result of breathing interventions. While suggestive of positive benefits, these studies used control groups that are either inactive or inappropriate for determining their respective mechanisms …


Disinhibition And Persistent Maladaptive Behavior, Angela T. West Jun 2021

Disinhibition And Persistent Maladaptive Behavior, Angela T. West

Student Theses

Objective: There is an urgent need to reduce overpopulation in U.S. prisons, which are inundated with individuals needing substance use treatment. Research on both substance use and antisocial behaviors highlight maladaptive beliefs and behaviors, while also implicating disinhibition as an important factor. Disinhibition is a dynamic trait that can be targeted with therapeutic interventions. The current study explored the relationships between neurocognitive disinhibition, substance use, and recidivism among incarcerated men. The study hypothesized that disinhibition would be associated with history of substance use, history of antisocial behavior, and institutional misconduct, as well as predicting recidivism over and above history of …


Variation In Personality Among Semi-Wild Myanmar Timber Elephants, Sateesh Venkatesh Dec 2020

Variation In Personality Among Semi-Wild Myanmar Timber Elephants, Sateesh Venkatesh

Theses and Dissertations

This study examines two personality traits: exploration and neophobia, which could influence human-elephant conflicts. Thirty-one semi-wild elephants were tested over two trials using a custom novel puzzle tube containing three tasks and three rewards. Our studies show that elephants do vary significantly between individuals in both exploration and neophobia.


The Effects Of Self-Esteem And Motivation On Cognitive Control, Andrea Benavides Jun 2020

The Effects Of Self-Esteem And Motivation On Cognitive Control, Andrea Benavides

Dissertations, Theses, and Capstone Projects

Cognitive control describes a set of mechanisms that guide behavior towards a goal (Cohen, 2017). The successful execution of cognitive control is essential for effective learning, information processing, problem solving, and academic achievement (Visu-Petra et al., 2011). The Expected Value of Control framework (EVC; Shenhav et al., 2013) suggests that control carries an inherent cost, which is weighed against the potential benefits of expending it. This cost-benefit analysis determines the direction and intensity that a goal is pursued. Importantly, motivation plays a role in this cost-benefit analysis and may function as the factor that offsets the cost of control expenditure …


Presence And Degree Of Contrafreeloading In African Grey Parrots (Psittacus Erithacus), Gabriella E. Smith May 2020

Presence And Degree Of Contrafreeloading In African Grey Parrots (Psittacus Erithacus), Gabriella E. Smith

Theses and Dissertations

This study examined contrafreeloading—choosing a physical task to access food over free food—in two Grey parrots (Psittacus erithacus). Both birds contrafreeloaded for food of equal or higher value, but differed in which contrafreeloading task they preferred. Differences between the parrots are considered as individual preferences for self-reinforcing tasks.


Harm And Victim Age As Factors In The Determination Of Intentionality And Culpability, Donal David Barnard Jr. Sep 2017

Harm And Victim Age As Factors In The Determination Of Intentionality And Culpability, Donal David Barnard Jr.

Dissertations, Theses, and Capstone Projects

In the United States criminal justice system, jurors are directed to determine a defendant’s guilt beyond a reasonable doubt by establishing both the act of committing a crime (actus reus) and the culpable mental state of the defendant (mens rea), that is, the defendant’s intentionality. The role of a juror in a criminal case is that of a factfinder, deciding whether the two elements of the crime have been met. Criminal cases where jurors are asked to decide the facts vary in the harm that resulted. The more severe the harm, the greater the perceived injustice. This …


Spatial-Relational Learning And Memory Deficits Associated With Nmdar Autoantibodies In Systemic Lupus Erythematosus, Brittany L. Bascetta Jun 2017

Spatial-Relational Learning And Memory Deficits Associated With Nmdar Autoantibodies In Systemic Lupus Erythematosus, Brittany L. Bascetta

Dissertations, Theses, and Capstone Projects

Individuals with Systemic Lupus Erythematosus (SLE) experience inflammation that may target any organ within the body, including the central and peripheral nervous systems. Additionally, these individuals often demonstrate psychological dysfunctions including emotional and cognitive deficits; however, research is inconsistent as to the nature and cause of these dysfunctions. While there are multiple factors that may increase risk for variability in cognitive function, such as population differences, socioeconomic status (SES), mood disorders (depression and anxiety), medication effects, and disease activity, these factors do not reliably predict the severity and extent of cognitive deficits. A growing body of animal research associates autoantibodies …


Hindsight Bias In Clinical Decision Making, Amanda Beltrani Jun 2017

Hindsight Bias In Clinical Decision Making, Amanda Beltrani

Student Theses

The tendency for an individual to believe that a specific event, in hindsight, was more predictable than it was in foresight is known as hindsight bias. This phenomenon has been demonstrated in the psychological literature across a variety of samples, methodologies, and predictions for decades. The current study used a sample of 95 mental health professionals to explore the impact of advanced outcome knowledge on the decision making process. Participants reviewed a hypothetical risk assessment in the form of a hospital chart and then responded to a series of questions, using only their clinical judgment. Analyses revealed that evaluators who …


An Analysis Of Canine Processing Of Stimulus Compounds Varying In Light And Sound Intensity, Katherine O. Compitus May 2016

An Analysis Of Canine Processing Of Stimulus Compounds Varying In Light And Sound Intensity, Katherine O. Compitus

Theses and Dissertations

A dog was trained to respond deferentially to two light-sound compounds. The dog was then tested with combinations of additional light and sound intensities. The dog appeared to use the information provided by both stimulus dimensions. This research is relevant to the understanding of information processing, specifically categorization and generalization.
