Psychological Factors And Gastrointestinal Symptoms During Running, Alex Michael Ehlert

Human Movement Studies & Special Education Theses & Dissertations

Gastrointestinal (GI) symptoms, such as nausea and gas, are common problems for athletes in endurance sport. There is considerable evidence that psychological factors influence GI function, but little research has evaluated this in the context of exercise-induced GI symptoms. The overall purpose of this dissertation was to explore the role of psychological factors in the incidence and management of GI symptoms during endurance running. Study 1 assessed associations between several psychological factors, GI symptoms, and nutrition intake before and during runs. Study 2 evaluated the effects of daily breathing interventions on GI symptoms, psychological factors, and heart rate variability (HRV) …

Intermittent Hypoxia And Effects On Early Learning/Memory: Exploring The Hippocampal Cellular Effects Of Pediatric Obstructive Sleep Apnea, Arvind Chandrakantan, Adam C Adler, Mehmet Tohsun, Farrah Kheradamand, Russell S Ray, Steven Roth

Faculty, Staff and Students Publications

This review provides an update on the neurocognitive phenotype of pediatric obstructive sleep apnea (OSA). Pediatric OSA is associated with neurocognitive deficits involving memory, learning, and executive functioning. Adenotonsillectomy (AT) is presently accepted as the first-line surgical treatment for pediatric OSA, but the executive function deficits do not resolve postsurgery, and the timeline for recovery remains unknown. This finding suggests that pediatric OSA potentially causes irreversible damage to multiple areas of the brain. The focus of this review is the hippocampus, 1 of the 2 major sites of postnatal neurogenesis, where new neurons are formed and integrated into existing circuitry …

The Psychedelic Renaissance: A Convergence Of Indigenous Knowledge And Science, Ronan K. Peck

University Honors Theses

In recent times, psychedelics have come back into the public eye, mostly through scientific intrigue about their healing potential. In the past decade, hundreds of studies have been conducted to explore the possible benefits, or risks, that these substances could bring to people – and there is great potential being found. This is the psychedelic renaissance, and with this phenomenon in full swing, it is important to take a step back and look at the full picture of our history with these substances. By doing so, it starts to become clear that psychedelics have guided human perception and understanding of …

A Tale Of Two Narratives: The Role Of Storytelling In Racial Dialogue, Lane Cooper

University Honors Theses

Storytelling is a tactic often used in intergroup dialogues as a means for highlighting the human aspect of intractable identity-based conflict. In the U.S., racial dialogues are a popular method for addressing racism and exposing the systems that enable its survival. However, stories told by People of Color during these dialogues are often met with denial, dismissiveness, and even complete silence by their White counterparts. This then leads to cognitive and emotional distress for the tellers and a lack of action from the listeners. Using a theoretical analysis, this paper reviews the narrative conflict around racism and applies psychological research …

The Literary Controversies Of Michelangelo's Sistine Ceiling, Victoria Duehring

The Forum: Journal of History

This literary review will focus on Michelangelo’s most significant work of color: the Sistine ceiling. Michelangelo’s work has spawned a plethora of literature, but this paper will focus on three main controversial topics: assistants (or lack thereof), the ignudi’s purpose, and restoration. I will also apply a psycho-historical approach to these controversies and identify potential avenues for future research.

Treatment Responses Among Youth With Anxiety Disorders And Body-Focused Repetitive Behaviors In A Clinic Sample, Katrina Scarimbolo

USF Tampa Graduate Theses and Dissertations

Anxiety disorders are considered to encompass multiple conditions, including generalized anxiety disorder, social anxiety disorder, separation anxiety disorder, panic disorder and specific phobias. Related conditions include post-traumatic stress disorder and obsessive and compulsive disorder. Body-focused repetitive behaviors (BFRBs) are a group of disorders that result in repetitive touching, picking, and/or pulling to areas of the body such as the scalp or skin (American Psychiatric Association, 2013). An anxiety disorder and a BFRB commonly co-occur in youth. This comorbid presentation produces further impairment in school attendance, peer socialization, or other functional domains. These difficulties youth experience make it pertinent to study …

Consistency And Inconsistency In Caregiver Reporting Of Vocabulary, Sudha Arunachalam, Valeryia Avtushka, Rhiannon Luyster, Whitney Guthrie

Emerson Authors, Researchers, & Creators

Vocabulary checklists completed by caregivers are a common way of measuring children’s vocabulary knowledge. We provide evidence from checklist data from 31 children with and without autism spectrum disorder. When asked to report twice about whether or not their child produces a particular word, caregivers are largely consistent in their responses, but where they are inconsistent, these inconsistencies affect verbs more than nouns. This difference holds both for caregivers of children with autism spectrum disorder and caregivers of typically-developing children. We suggest that caregivers may be less sure of their child’s knowledge about verbs than nouns. This data converges with …

Measuring State Empathy: Exploring The Efficacy Of A Film Clip Task And Examining Individual Differences In Empathic Responding, Stephanie R. Hruza

USF Tampa Graduate Theses and Dissertations

The study of trait empathy and the experience of empathy has implications for psychopathologies, the enactment of prosocial behaviors, and inhibition of aggression. For the most part, studies on empathy have been limited to the examination of trait empathy and/or empathy-related prosocial behaviors. However, to better understand how trait empathy may translate into empathy-related behaviors, it is important to find the best ways to elicit and measure state empathy, as well as characterize the relationship between trait and state empathy. Additionally, research into the relationship between normal-range personality traits and empathy on both a trait and state level has largely …

Quantifying The Speed Of Chromatophore Activity At The Single-Organ Level In Response To A Visual Startle Stimulus In Living, Intact Squid, Stavros P. Hadjisolomou, Rita W. El-Haddad, Kamil Kloskowski, Alla Chavarga, Israel Abramov

Publications and Research

The speed of adaptive body patterning in coleoid cephalopods is unmatched in the natural world. While the literature frequently reports their remarkable ability to change coloration significantly faster than other species, there is limited research on the temporal dynamics of rapid chromatophore coordination underlying body patterning in living, intact animals. In this exploratory pilot study, we aimed to measure chromatophore activity in response to a light flash stimulus in seven squid, Doryteuthis pealeii. We video-recorded the head/arms, mantle, and fin when squid were presented with a light flash startle stimulus. Individual chromatophores were detected and tracked over time using image …

An Integrative Review Of Fathers' Needs During The Transition To Fatherhood: Implications For Perinatal Education, Carli Cox

University Honors Theses

Aim: To examine the needs and experiences of fathers during the transition to fatherhood with the intent of improving perinatal education for fathers.

Background: The perinatal period is a highly transformational time for parents with implications in mental health, role development, identity formation, and relationship changes, to name a few. Unfortunately, research on fathers' needs and experiences during this time is limited, which consequentially restricts the development of father-inclusive perinatal education.

Method: An electronic search for qualitative studies was conducted using the PsycInfo database. Results were narrowed by a set of criteria and chosen studies' results were analyzed and organized …

“If You Didn’T Mean It, Why Did I Feel It?”: Comparing The Effects Of Deliberate Vs. Unintentional Ostracism, Andrea L. Sanders

College of Science and Health Theses and Dissertations

Ostracism is a form of social exclusion characterized primarily by the experience of being ignored in a social situation. Ostracism is psychologically significant not only because it separates us from desirable social interactions but also because it provides information about how others view us. Investigations of seemingly deliberate ostracism have consistently shown that exclusion threatens people’s sense of self; yet little research directly compares how consequences differ when people believe they were excluded deliberately versus unintentionally. Across five studies, we explored whether the ostracizer’s perceived intent to exclude affected participants sense of self and their subsequent thoughts, feelings and behaviors. …

Reducing Prejudice Through Law: Evidence From Experimental Psychology, Roseanna Sommers, Sara Burke

Law & Economics Working Papers

Can antidiscrimination law effect changes in public attitudes toward minority groups? Could learning, for instance, that employment discrimination against people with clinical depression is illegal cause members of the public to be more accepting toward people with mental health conditions? In this Article, we report the results of a series of experiments that test the effect of inducing the belief that discrimination against a given group is legal (vs. illegal) on interpersonal attitudes toward members of that group. We find that learning that discrimination is unlawful does not simply lead people to believe that an employer is more likely to …

Development Of The Infant Gut Microbiome Predicts Temperament Across The First Year Of Life, Molly Fox, S. Melanie Lee, Kyle S. Wiley, Venu Lagishetty, Curt A. Sandman, Jonathan P. Jacobs, Laura M. Glynn

Psychology Faculty Articles and Research

Perturbations to the gut microbiome are implicated in altered neurodevelopmental trajectories that may shape life span risk for emotion dysregulation and affective disorders. However, the sensitive periods during which the microbiome may influence neurodevelopment remain understudied. We investigated relationships between gut microbiome composition across infancy and temperament at 12 months of age. In 67 infants, we examined if gut microbiome composition assessed at 1–3 weeks, 2, 6, and 12 months of age was associated with temperament at age 12 months. Stool samples were sequenced using the 16S Illumina MiSeq platform. Temperament was assessed using the Infant Behavior Questionnaire-Revised (IBQ-R). Beta …

A Systematic Literature Review Of Sexual Harassment Studies With Text Mining, Amir Karami, Melek Yildiz Spinel, Nicole White, Kayla Ford, Suzanne Swan

Faculty Publications

Sexual harassment has been the topic of thousands of research articles in the 20th and 21st centuries. Several review papers have been developed to synthesize the literature about sexual harassment. While traditional literature review studies provide valuable insights, these studies have some limitations including analyzing a limited number of papers, being time-consuming and labor-intensive, focusing on a few topics, and lacking temporal trend analysis. To address these limitations, this paper employs both computational and qualitative approaches to identify major research topics, explore temporal trends of sexual harassment topics over the past few decades, and point to future possible directions in …

Material Encounters: Making Memory Beyond The Mind, Ariel Wills

Masters Theses

Can acts of making carry the memories of our embeddedness within the world? This thesis explores how making things can nurture a sense of kinship that cuts across the organic and inorganic, erasing the distinction between living and dead, material and spiritual. Through handwork such as art-making, sewing, knitting, cooking, woodworking, and beyond, the burden of remembering and of archiving is shared across human and non-human bodies, cultivated through practices of making, and through the materials themselves. By recounting the stories of my family’s experience as Jewish immigrants in the United States, I aim to reveal how their domestic practices …

S-Equol Mitigates Motivational Deficits And Dysregulation Associated With Hiv-1, Kristen A. Mclaurin, Sarah J. Bertrand, Jessica M. Illenberger, Steven B. Harrod, Charles F. Mactutus, Rosemarie M. Booze

Faculty Publications

Motivational deficits (e.g., apathy) and dysregulation (e.g., addiction) in HIV-1 seropositive individuals, despite treatment with combination antiretroviral therapy, necessitates the development of innovative adjunctive therapeutics. S-Equol (SE), a selective estrogen receptor beta agonist, has been implicated as a neuroprotective and/or neurorestorative therapeutic for HIV-1 associated neurocognitive disorders (HAND); its therapeutic utility for motivational alterations, however, has yet to be systematically evaluated. Thus, HIV-1 transgenic (Tg) and control animals were treated with either a daily oral dose of SE (0.2 mg) or vehicle and assessed in a series of tasks to evaluate goal-directed and drug-seeking behavior. First, at the genotypic level, …

Failure To Report: The Detrimental Effects Following Sexual Assault, Lindsey R. Osborne

Intuition: The BYU Undergraduate Journal of Psychology

Sexual assault is a prominent issue in society, yet many people remain unaware of the serious effects following sexual assault. Victims who report to legal authorities tend to experience disbelief and blame because of the prevalence of rape myths. Due to the severity of the trauma, hormones released by the brain hinder proper brain functioning and can cause a little-known evolutionary response termed tonic immobility (TI). The psychological outcome of sexual assault commonly results in or worsens several psychological conditions, including depression, anxiety, PTSD, and drug and alcohol abuse. Guilt, self-blame, and adverse emotions are accelerated with negative interactions while …

Identifying Optimal Course Structures Using Topic Models, Tehut Tesfaye Biru

Dartmouth College Undergraduate Theses

This research project investigates whether there exists an optimal way to structure topics in educational course content that results in higher levels of engagement among students. It is implemented by fitting topic models to transcripts of educational videos contained in the Khan Academy platform. The fitted models were used to extract topic trajectories across time for each video and subsequently clustered based on whether they have similar “shapes”. The differences in mean engagement metrics per cluster suggest that some course shapes are more palatable to students regardless of subject matter. Additionally, the topic trajectories suggest a constant progression of topics …

Shame Proneness As A Vulnerability Factor For Negative Emotions In The Context Of Interpersonal Stressors: An Experience Sampling Study, Oxana L. Stebbins

Clinical Psychology Dissertations

Shame proneness is associated with psychopathology and may serve as a risk factor for experiencing distressing emotions at subclinical and clinical levels across diagnoses. Additionally, shame-prone individuals may have increased sensitivity toward interpersonal stressors and negative shifts in self-evaluations. However, little to no research has examined shame proneness as a prospective risk factor for distressed moods following interpersonal stressors using experience sampling methods. Furthermore, disagreement on theories of shame make it difficult to achieve consistent results in the literature. The purpose of this study was to assess whether shame proneness acts as a risk factor for distressed moods in the …

Homo Psyche: On Queer Theory And Erotophobia [Chapter 6], Gila Ashtor

Literature

Can queer theory be erotophobic? This book proceeds from the perplexing observation that for all of its political agita, rhetorical virtuosity, and intellectual restlessness, queer theory conforms to a model of erotic life that is psychologically conservative and narrow. Even after several decades of combative, dazzling, irreverent queer critical thought, the field remains far from grasping that sexuality’s radical potential lies in its being understood as “exogenous, intersubjective and intrusive” (Laplanche). In particular, and despite the pervasiveness and popularity of recent calls to deconstruct the ideological foundations of contemporary queer thought, no study has as yet considered or in …

To Switch Or Not To Switch: Individual Differences In Executive Function And Emotion Regulation Flexibility, Wei Xing Toh

Dissertations and Theses Collection (Open Access)

Emotion regulation (ER) constitutes strategies that modulate the experience and expression of emotions. While past work has predominantly focused on each ER strategy independently, recent research has begun to examine individual-difference factors that are associated with the flexible implementation of ER strategies in line with environmental demands (i.e., ER flexibility). Considering that ER processes generally implicate executive function (EF)—a collection of adaptive, general-purpose control processes—it is plausible that EF could be involved in ER flexibility. Using a latent-variable approach based on a comprehensive battery of EF tasks, the present study investigated how the various aspects of EF (i.e., common EF, …

Familiarity And Mate Preference Assessment With The Partner Preference Test, Annaliese K. Beery

Psychology: Faculty Publications

In contrast to traditional laboratory animals, prairie voles form socially monogamous partnerships in the wild and exhibit lasting social preferences for familiar individuals-both mates and same-sex peers-in the laboratory. Decades of research into the mechanisms supporting pair bonding behavior have made prairie voles an important model organism for the study of social relationships. The partner preference test is a laboratory test of familiarity preference that takes place over an extended interval (typically 3 hr), during which test subjects can directly interact with conspecifics and often engage in resting side-by-side contact (i.e., huddling). The use of this test has enabled study …

Natural Variation In The Oxytocin Receptor Gene And Rearing Interact To Influence Reproductive And Nonreproductive Social Behavior And Receptor Binding, Todd H. Ahern, Sara Olsen, Ryan Tudino, Annaliese K. Beery

Psychology: Faculty Publications

Individual variation in social behavior offers an opportunity to explore gene-by-environment interactions that could contribute to adaptative or atypical behavioral profiles (e.g., autism spectrum disorders). Outbred, socially monogamous prairie voles provide an excellent model to experimentally explore how natural variations in rearing and genetic diversity interact to shape reproductive and nonreproductive social behavior. In this study, we manipulated rearing (biparental versus dam-only), genotyped the intronic NT213739 single nucleotide polymorphism (SNP) of the oxytocin receptor gene (Oxtr), and then assessed how each factor and their interaction related to reciprocal interactions and partner preference in male and female adult prairie voles. We …

From Psychology To Phylogeny: Bridging Levels Of Analysis In Cultural Evolution, Mason Youngblood

Dissertations, Theses, and Capstone Projects

Cultural evolution, or change in the socially learned behavior of a population over time, is a fascinating phenomenon that is widespread in humans and present in some non-human animals. In this dissertation, I present an array of cultural evolutionary studies that bridge pattern and process in a wide range of research models including music, extremism, and birdsong. The first chapter is an introduction to the field of cultural evolution, including a bibliometric analysis of its structure. The second and third chapters are studies on the cultural dynamics of music sampling traditions in hip-hop and electronic music communities and far-right extremism …

Delayed Modulation Of Glutamate Receptors By Anti-Epileptic Drugs After Traumatic Brain Injury In Rats, Edgar Rodriguez

Dissertations, Theses, and Capstone Projects

Traumatic brain injury (TBI) is a significant health concern. Around 74 million people sustain a traumatic brain injury worldwide. The damage caused by TBI produces two types of injury; primary and secondary injuries. Primary injury is caused within milliseconds and is irreversible. Secondary brain injury is delayed and produced by molecular, cellular, and structural disruption after the initial injury. One of the most devastating dysfunction after TBI is glutamate neurotransmitter overactivation that could lead to neurotoxic levels of glutamate in the brain (i.e., excitotoxicity). Excitotoxicity has been linked with the development of epilepsy after TBI, also known as post-traumatic epilepsy …

Circuits Underlying Serotonin Mediated Sex Differences In Fear Learning, Rebecca Ravenelle

Dissertations, Theses, and Capstone Projects

Post-traumatic stress disorder (PTSD) is a trauma-related disorder characterized by intense fearful memory formation. Women are twice as likely as men to develop PTSD, indicating there may be sex differences in the underlying neural circuits. Given that serotonin (5-HT) dysfunction is implicated in PTSD, and 5-HT modulates fear learning, we investigated whether there are sex differences in the modulation of fear learning by 5-HT. We administered the selective serotonin reuptake inhibitor (SSRI) citalopram (20mg/kg or 10m/kg, i.p.) once to male and female mice prior to auditory fear conditioning and tested the effects on fear memory the next day. We found …

Examining The Transient Neural Dynamics Underlying Working Memory Maintenance For Complex Visual Stimuli, Chelsea Reichert Plaska

Dissertations, Theses, and Capstone Projects

Working memory (WM) is the temporary storage of information to accomplish a future goal. The WM delay period is the time after encoding but before retrieval when information is being maintained, typically in the absence of relevant stimuli. Understanding how the brain supports maintenance during the delay period, and how neural activity and connectivity are related to memory is critical for advancing both basic knowledge as well as informing declines in memory and cognition related to neurodegenerative diseases and healthy aging. An open question in the field of WM research is how information is stored during this delay period. One …

A Neuroscientist's Guide To The Vole, William M. Kenkel, Morgan L. Gustison, Annaliese K. Beery

Psychology: Faculty Publications

Prairie voles have emerged as an important rodent model for understanding the neuroscience of social behavior. Prairie voles are well known for their capacity for pair bonding and alloparental care. These behavioral phenomena overlap with human social behavior but are not commonly observed in traditional rodent models. In this article, we highlight the many benefits of using prairie voles in neuroscience research. We begin by describing the advantages of using diverse and non-traditional study models. We then focus on social behaviors, including pair bonding, alloparental care, and peer interactions, that have brought voles to the forefront of social neuroscience. We …

Micro-Expressions Of Fear During The 2016 Presidential Campaign Trail: Their Influence On Trait Perceptions Of Donald Trump, Patrick A. Stewart, Elena Svetieva

Political Science Faculty Publications and Presentations

The 2016 United States presidential election was exceptional for many reasons; most notably the extreme division between supporters of Donald Trump and Hillary Clinton. In an election that turned more upon the character traits of the candidates than their policy positions, there is reason to believe that the non-verbal performances of the candidates influenced attitudes toward the candidates. Two studies, before Election Day, experimentally tested the influence of Trump’s micro-expressions of fear during his Republican National Convention nomination acceptance speech on how viewers evaluated his key leadership traits of competence and trustworthiness. Results from Study 1, conducted 3 weeks prior …

Taste Activity In The Parabrachial Region In Adult Rats Following Neonatal Chorda Tympani Transection, Louis J. Martin, Joseph M. Breza, Suzanne I. Sollars

Psychology Faculty Publications

The chorda tympani is a gustatory nerve that fails to regenerate if sectioned in rats 10 days of age or younger. This early denervation causes an abnormally high preference for NH₄Cl in adult rats, but the impact of neonatal chorda tympani transection on the development of the gustatory hindbrain is unclear. Here, we tested the effect of neonatal chorda tympani transection (CTX) on gustatory responses in the parabrachial nucleus (PbN). We recorded in vivo extracellular spikes in single PbN units of urethane-anesthetized adult rats following CTX at P5 (chronic CTX group) or immediately prior to recording (acute CTX …
