Behavioral And Neuroanatomical Outcomes Of Early And Late Preterm Hypoxic-Ischemic Injury And The Neuroprotective Effects Of Whole-Body Hypothermia: An Animal Model, Haley C. Garbus

University Scholar Projects

The overarching aims of this research were: first, to characterize the anatomical and behavioral effects of preterm hypoxic-ischemic (HI) injury in rodent models; and second, to explore the method of passively induced whole-body hypothermia as a neuroprotective intervention following HI. Clinical research of preterm injured infants has shown a large range of behavioral deficits, including delays in language learning, spatial and non-spatial memory, visual attention, and motor coordination. The current studies focused on these behavioral abnormalities, using HI rodent models. Specifically, we explored a model for early preterm HI (HI induced on postnatal day (P) 3 in rats), and compared …

Monitering And Addressing Light Pollution At Utah State University, Rachel Kim Nydegger

Undergraduate Honors Capstone Projects

Many outdoor light fixtures illuminate in all directions, meaning that a large portion of light is emitted upwards. This excess light - light pollution - represents wasted energy and money, decreases public safety, is a health hazard for humans as well as wildlife, and inhibits the view of the night sky. In order to quantify the anthropogenic contribution of local light pollution, I studied detection methods at the National Optical Astronomy Observatory though a summer REU in 2013. Upon my return to USU, I monitored the night sky brightness from September 2013 to April 2015 at Utah State University. Due …

Cue Reactivity To Images Of Alcohol: Creation Of A Standardized Picture Set, Kelsey M. Krueger

Theses - ALL

To study alcohol approach inclinations in a laboratory setting, researchers commonly use cue reactivity paradigms involving presentation of alcohol cues and measurement of responses. However, available picture sets present potential limitations due to their multidimensional nature. A critical task was to develop a set of standardized images without brand labels, actors, or settings, in order to gain a clearer assessment of college students’ reactions to alcohol, and alcohol alone, while minimizing contextual influences. In Study 1, a set of images with satisfactory reliability was created. To replicate and expand upon these findings, Study 2 included a sample of 163 participants …

Intersectional Invisibility: A Comparison Among Caucasian, African-American, And Latino Men And Women, De'siree Reeves

HIM 1990-2015

The objective of this thesis was to investigate intersectional (categorical/social) invisibility and the extent to which this phenomenon occurs in a comparison of dominant (i.e., Caucasian), and non-dominant (African-American and Latino) social/ethnic groups. It has been found that intersectional invisibility occurs among African-American women with respect to Caucasian men and women, and African American men (Sesko & Biernat, 2010), but little of this research has been done regarding Latinas. Thus, this experiment aims to not only examine whether Latinas are also subject to intersectional invisibility among dominant (i.e., Caucasian) and non-dominant (i.e., African American and/or Latino) groups, but to determine …

Investigation Of Automatic Access To Spatial Representations Of Magnitude, Jaclyn Marie Wiener

Theses, Dissertations and Culminating Projects

In the SNARC (Spatial Numeric Association of Response Codes) effect relatively small numbers are processed faster on the left hand side and relatively large numbers are processed faster on the right hand side, implying a spatial mental representation of numbers that might be conceptualized as a mental number line (Dehaene, Bossini, & Giraux, 1993). Walsh (2003) proposed that time, space, and quantity are part of a generalized cognitive system that processes different facets of magnitude. If this is true, we investigated whether the SNARC-like effect reported with magnitude of circle is a strong or weak automatic process. In the case …

The Impact Of Childhood Trauma As Moderated By Ptsd, Relationship With Caregiver, And Rumination, Aislyn M. Allen

USC Aiken Psychology Theses

The current study explored the relationship between childhood trauma and deliberate rumination, as well as PTSD symptomology, psychological and physiological functioning. Participants consisted of 55 undergraduate students, ages 18-23; who completed measures about a specific traumatic event, psychological functioning, parental attachment, PTSD symptoms, deliberate rumination, childhood maltreatment, and a demographics questionnaire. Reported childhood trauma was a specifically identified traumatic life event, child maltreatment, or having a parent with a substance abuse or mental disorder. Following completion of measures, participants were asked to answer questions while heart rate, heart rate variability, and electrodermal activity were monitored. Results indicated there was relation …

Spike Field Coherence (Sfc) For Ripples In Rat Hippocampus, Pranav Singla

Honors Scholar Theses

The aim of this project was to determine coherence between two types of neural recordings which can be obtained from the rat hippocampus: spikes and local field potentials. Extracellular recording makes it possible to determine spiking activity from individual neurons in the vicinity of the recording electrode. Local field potential recording gives a combined activity of many neurons (thousands) at once to determine an overall picture of the coordination of the cells in real time. Here we examine the relationship between these two signals, focusing on place cells which spike at their maximal rate only at certain positions in physical …

The Effects Of Perceived Enjoyable Activities On Cognition In Late-Life., Hannah D. Gardner

College of Arts & Sciences Senior Theses

Previous research suggests that more involvement in various activities can help delay cognitive decline in older adults. Few studies have examined both the impact of frequency and perceived enjoyment of different types of activities on cognition. This study analyzed the relationship between frequency and pleasure of activities and cognition by running correlations using the five different subscales of the California Older Person’s Pleasant Events Schedule (COPPES) and a battery of cognitive tests (Block Design, Animal Naming, Boston Naming Test, Trails A, Trails B, CVLT-LDFR, & Digit Span). It was hypothesized that higher frequency as well as higher level of enjoyment …

A Psychophysiological Investigation Of The Proposed Paradoxical Effects Of Valuing Happiness, Nicholas Coles

HIM 1990-2015

Several researchers in happiness studies have called for an increased sociopolitical interest in indicators of societal happiness. However, recent evidence for the proposed paradoxical effects of valuing happiness suggest that an increase in society’s perceived value of happiness may exert a detrimental, inverse influence on well-being. This notion is based on previous research demonstrating that manipulating participants to value happiness causes them to experience less positive emotions, compared to controls, when viewing positive film clips. Following the humanistic notion that the maximization of societal happiness is an advantageous sociopolitical endeavor, the proposed paradoxical effects of valuing happiness present a psychological …

Preferences For Evidence-Based Depression Treatments: An Emphasis On Patient-Focused Care, Lauren A. Frye

Dissertations

Research indicates most depressed patients in the general U.S. adult population seek depression treatment in primary care settings where the prevailing method of treatment is antidepressant medication. Although primary care physicians regard this approach as a preferable first line method of depression treatment, studies indicate many patients do not. Several studies have found depressed patients in these settings prefer psychotherapy or counseling over anti-depressant medication. Many advocate patient preferences should be integral to the treatment decision making process. There is a demonstrated propensity towards psychotherapy or counseling over antidepressant medication among depression patients. However, it is unclear which psychological depression …

Do Semantic Contextual Cues Facilitate Transfer Learning From Video In Toddlers?, Laura Zimmermann, Alecia Moser, Amanda Grenell, Kelly Dickerson, Qianwen Yao, Peter Gerhardstein, Rachel Barr

Psychology Faculty Scholarship

Young children typically demonstrate a transfer deficit, learning less from video than live presentations. Semantically meaningful context has been demonstrated to enhance learning in young children. We examined the effect of a semantically meaningful context on toddlers' imitation performance. Two- and 2.5-year-olds participated in a puzzle imitation task to examine learning from either a live or televised model. The model demonstrated how to assemble a three-piece puzzle to make a fish or a boat, with the puzzle demonstration occurring against a semantically meaningful background context (ocean) or a yellow background (no context). Participants in the video condition performed significantly worse …

Inverse Changes In Ghrelin And A2a Receptor Gene Expression Levels In The Hippocampus Of Heart Failure Canines Following Spinal Cord Stimulation, Benjamin E. Jewett

Undergraduate Honors Theses

Myocardial infarction (MI), often referred to as a heart attack, is a serious health issue in the United States. There is a well-documented link between MI and major depressive disorder (MDD), with a high incidence of MDD occurring after an MI. Overlapping pathologies have been observed within the hippocampus of the brain in animal models of MI and depression. These observations suggest that pathobiological cross-talk between the heart and brain could have a role in the etiology of MDD that occurs after an MI. Spinal cord stimulation (SCS) has previously been shown to have both cardioprotective and neuroprotective effects post-MI, …

The Synergistic Effects Of Methylphenidate On The Behavioral Effects Of Nicotine, Kristen K. Leedy

Undergraduate Honors Theses

One of the most common childhood disorders, attention-deficit hyperactivity disorder (ADHD) places individuals at a higher risk for nicotine (NIC) dependence. Approximately 37.2% of individuals with ADHD currently smoke compared to the 18.3% of individuals with no record of mental illness. Methylphenidate (MPH; Trade name Ritalin) is the most commonly prescribed treatment for ADHD. Research regarding the synergistic effects of MPH and NIC, however, is divided. Some research indicates that MPH may enhance susceptibility to NIC effects, whereas other studies report that MPH may inhibit sensitization to NIC. The present study examines the effects of pre-exposure to MPH (1.0 mg/kg) …

Effects Of Adverse Childhood Experiences On High Risk Inpatients Criminal Behavior, Alexis L. Booth, Jill D. Stinson Phd

Undergraduate Honors Theses

Adverse childhood experiences (ACEs) play a role in the development of chronic mental and physical diseases in adulthood. These experiences include adversities such as: emotional/verbal abuse, sexual abuse, physical abuse, and household dysfunction. In this study, we hypothesize that forensic mental health offenders will have higher ACE scores than community participants. Secondly, we hypothesize that these participants will show higher rates of and earlier incidences of offending, arrest, incarceration, and hospitalization as a result of their ACE scores. Further, we hypothesize that males and females will be affected by ACEs differently. Using archival data from a secure forensic psychiatric facility …

Can Dolphins Cooperate To Solve A Novel Task?, Kelley Ann Winship

Master's Theses

Bottlenose dolphins cooperate in a variety of contexts, including foraging,acquiring mates, playing, and assisting distressed conspecifics. To better understand the capacity for cooperative behaviors, animals are often given tasks that require pairs of animals to coordinate their actions in order to receive a reward. This paper reports the results of an aquatic version of one such task: cooperative rope-pulling. Three groups of captive bottlenose dolphins (Tursiops truncatus) were given an apparatus that could most easily be opened by the two animals working together. Two untrained adult males at one location were successful in opening the apparatus together, sharing …

The Relationship Between Receptacle Design, Normative Conduct, Environmental Concerns, And Recycling Behavior, Molly Arnold

Honors Theses

Conservation psychology is a growing field that explores how people interact with and interpret their roles in the environment. I conducted a three part study that incorporates conservation psychology principles to examine the effects of recycling bin design and normative conduct on recycling behavior as well as the ecological orientation of UTC students based on survey responses. Experiment 1 compared two recycling bin conditions (non-lidded bin vs. bin covered with a lid with two holes indicating the shape of recyclables) to determine which bin design was more effective in promoting recycling behavior. No difference was found between the two designs. …

Oscillatory Activity In The Subthalamic Nucleus And Motor Cortex In A Pharmacological Model Of Parkinsonian Tremor, Aileen F. Haque

Honors Scholar Theses

Parkinson’s Disease (PD) is a motor disorder with symptoms including resting tremor, akinesia, bradykinesia, and rigidity. A major neuropathological feature of PD is degeneration of nigrostriatal dopamine (DA) neurons. The resulting DA depletions lead to the production of severe motor deficits. Pharmacological agents that reduce DA transmission can also induce these motor abnormalities. In addition to the involvement of DA, drugs acting on acetylcholine, namely cholinomimetics, can induce or exacerbate Parkinsonian symptoms. In humans, one of the main motor symptoms associated with PD is resting tremor, occurring at a frequency of 3-7 Hz. This can be modeled in rodents using …

Endocrine And Psychophysiological Correlates Of Jealousy And Social Anxiety In Healthy Adults: Elevated Responses To Inter-Male Competition, Bethany H. Mccurdy

Senior Honors Theses

Male mammals compete for reproductive access to females. Gaining and maintaining this access can be stressful and anxiety-provoking. In humans, anxiety and associated protective behaviors can manifest as jealousy. Physiological stress is likely to increase in relation to jealousy as it does with anxiety. Hypothetically, higher levels of anxiety and cortisol may indicate, and may even promote, strong territorial or jealous behavior. Chronically elevated cortisol has been shown to be deleterious to prefrontal and hippocampal neurons and result in emotional and stress-response dysregulation. In very anxious and jealous individuals, chronic stress activation could further promote these tendencies via emotional disinhibition. …

Relationship Of Nutritional Factors To Cognitive Decline In The Progression Of Dementia: The Cache County Dementia Progression Study, Chelsea Sanders

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Cache County Memory Study at Utah State University studied longitudinal changes in memory and aging in a population-based sample of 5,092 older adults in semirural Cache County, UT. Three hundred twenty-eight participants with dementia were identified through a multi-staged screening and assessment protocol and visited semiannually for up to 8 years in the Dementia Progression Study (DPS). The current project reviews data from the first 6 years due to attrition in later years. Researchers collected information regarding the participants’ demographics, health, lifestyle (nutrition and physical activity), cognitive abilities and neuropsychiatric symptoms as well as their caregivers’ demographics, health, and …

Sexual Orientation Change Efforts, Identity Conflict, And Psychosocial Health Amongst Same-Sex Attracted Mormons, John P. Dehlin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Both religiosity and sexuality are acknowledged by the American Psychological Association as important considerations for overall psychosocial well-being. Consequently, the denunciation of same-sex sexuality as sinful by many religious organizations leads many lesbian, gay, bisexual, and transgender individuals to experience significant identity conflict. Historically, conservative religious institutions such as The Church of Jesus Christ of Latter-day Saints (Mormons) have offered
developmental (i.e., nonbiological) explanations as to the origins of same sexuality, along with various nonaffirming approaches including: (a) sexual orientation change efforts, (b) increased religious devotion, (c) celibacy, and (d) mixed-orientation (heterosexual) marriage. However, relatively little research has been conducted …

Presence-At-Hand, Eric Lyle Schultz

Graduate School of Art Theses

Abstract

The writing that follows is intended to provide a theoretical framework for the motives behind my practice. The primary concerns addressed are the reception, transmission, and physical shape of knowledge. I will discuss a human condition that exists as a byproduct of both the legacy of representation as well as the innate biology of the brain. I will argue that as a society we are governed by the residue of an extreme logic, and that this condition places severe margins on our potential for creative solutions. I will propose that our ability to create meaning is stifled by the …

Functional Capacity In Schizophrenia: Relationship Among Effort, Reinforcement Learning And Self-Beliefs, Sally J. Vogel

UNLV Theses, Dissertations, Professional Papers, and Capstones

Individuals with schizophrenia exhibit a wide range of complex neurocognitive, psychiatric and behavioral impairments. Recent research suggests that this complex array of symptoms can be at least partially accounted for by dysfunction in more basic mechanisms, such as the ability to learn from positive and negative reinforcement, or the ability to exert adequate effort when completing simple tasks. Evidence also suggests that deficits in these basic mechanisms may contribute to more complex symptoms, such as functional impairment. Also, the relationship between neurocognitive deficits and functional impairment has been found to be mediated by defeatist performance beliefs. However, studies have not …

Experience-Specific And Domain-General Effects On Simple And Complex Meter Processing, Sangeeta Gupta

UNLV Theses, Dissertations, Professional Papers, and Capstones

Our ability to process rhythmic patterns is constrained by the complexity of its interval structure. The goal of the present study was to explore the cognitive demands and neural mechanisms for processing simple and complex meters, and the extent to which they are modulated by culture-specific experience. The first experiment explored the argument that perception of rhythm is guided by a domain-general ability to process quantity, and that processing simple and complex meter rhythms requires different cognitive strategies. Rhythm perception was assessed by testing listeners’ ability to detect disruptions in simple and complex meter melodies. Proficiency with numerosity judgments was …

Playful Aggression And The Situational Contexts That Affect Perceptions, Jennifer Hart

UNLV Theses, Dissertations, Professional Papers, and Capstones

Play is considered a fundamental tool for early childhood education practices as it provides numerous developmental benefits for young children. However, not all play is viewed by children, parents, and early childhood educators the same, especially playful aggression. For example, rough-and-tumble play, risky play, superhero play, “bad guy” play, active pretend play, play fighting, big body play, war play, gun play, and physically active and imaginative play are types of playful aggression that benefits young children’s development; but are often viewed negatively by the adults who observe it. The contextual factors that influence the development of these conflicting perceptions—the motivation …

A Comparison Of The Effects Of Different Doses Of Gabab Receptor Ligands On Spatial Learning And Memory And Memory Flexibility, Chelcie Heaney

UNLV Theses, Dissertations, Professional Papers, and Capstones

The principal inhibitory neurotransmitter in the brain, gamma amino-butyric acid (GABA), mediates several types of learning and memory. Of the two main receptor subtypes for GABA, the in vivo role of GABAB receptor in learning and memory is less well characterized and the current data often conflict. Based on the current literature, it is unclear, for instance, whether enhancing GABAergic activity via the GABAB receptor could be beneficial for or detrimental to learning and memory. Hippocampally-dependent learning and memory tasks are of particular interest due to their clinical relevance to patients with schizophrenia or Alzheimer’s disease, who exhibit impaired performance …
