E-Cigarette Impacts On Aspects Of Dementia: Basic Research, Daniel S. Da Silva, Lucy N. Scribner

Student Research Symposium

E-cigarettes and Dementia

• Although smoking has declined in recent years, e-cigarette (vaping) use has drastically increased, particularly in youth.
• Smoking escalates risk for vascular dementia, with women more impacted than men.
• Dementia - Impaired capacity to remember, which interferes with the ability to perform daily functions.

Understanding The Relationship Between Choice Of Pet And Priorities In An Intimate Relationship - A Research Proposal, Kaitlyn Guthrie

2024 Student Academic Showcase

This proposed research study aims to see if an individual’s choice of pet reflect the things that they value most in an intimate relationship. Pets have become more popular over the years, and a common theme for choosing a pet is whether or not the animal will be a good fit for the individual’s lifestyle. Since dogs are known to be social and affectionate creatures, I believe that individuals who have pet dogs may require more physical affection and a sense of togetherness in an intimate relationship in order to feel satisfied. I believe that individuals who own cats, though …

The Effects Of Acute And Chronic Ethanol Exposure On Mouse Spontaneous Spatial Behaviors, Tia Donaldson

Psychology ETDs

Within the open field, rodents spontaneously explore their surroundings by alternating between stops (absence of movement) and progressions (locomotion between locations). Few studies have examined how alcohol influences the organization of these spatial behaviors; therefore, we evaluated the effects of acute single-dose and binge-like alcohol exposure on spontaneous open-field behaviors. In Experiment 1, adults received a single injection of ethanol and explored a dark environment for 30 minutes. We found that mice assessed immediately after the injection exhibited reductions in locomotion and spontaneous behavior, while those tested 30 minutes later only exhibited suppressed locomotion. In Experiment 2, adolescent/adult mice received …

The Role Of Spreading Depolarizations In Mild Traumatic Brain Injuries, Natalie J. Pinkowski

Biomedical Sciences ETDs

Mild traumatic brain injuries (mTBIs) often lead to acute symptoms like disorientation and discoordination, but the underlying mechanisms are unknown. Although most patients recover quickly from a single mTBI, repeated injuries can be debilitating. After an mTBI, a neurometabolic cascade produces metabolic burden and vulnerability. Spreading depolarizations (SDs) have been observed after mTBIs. Here we investigated SDs’ role in short-term motor behavioral deficits post-mTBI. We hypothesized that SDs contribute to the deficits, and exacerbated symptoms after repeated mTBIs. To test this, we used acute motor behavioral tests and long-term behavioral and cognitive tests after initiating SDs by mTBI, chemical, or …

Starting Small Or Big: An Artificial Language Paradigm, Rachel Evans

LSU Master's Theses

Previous research on language acquisition has raised two competing hypotheses: Starting Small and Starting Big. Starting Small states that limitations (small working memory capacity, simple structure, short string length, etc.) are beneficial for language learning, which explains why children are able to acquire language more easily than adults. Starting Big proposes the opposite, that input of chunks of language rather than individual units creates a stronger and more fluid understanding of grammatical relations between words. The current study aimed to investigate these theories in the context of an artificial language paradigm using a forced-choice task, a production task, a working …

Sex Differences And Sex‑Specific Regulation Of Motivated Behavior By Melanin‑Concentrating Hormone: A Short Review, Isabel R. K. Kuebler, Mauricio Suárez, Ken T. Wakabayashi

Department of Psychology: Faculty Publications

Recent preclinical research exploring how neuropeptide transmitter systems regulate motivated behavior reveal the increasing importance of sex as a critical biological variable. Neuropeptide systems and their central circuits both contribute to sex differences in a range of motivated behaviors and regulate sex-specific behaviors. In this short review, we explore the current research of how sex as a biological variable influences several distinct motivated behaviors that are modulated by the melanin-concentrating hormone (MCH) neuropeptide system. First, we review how MCH regulates feeding behavior within the context of energy homeostasis differently between male and female rodents. Then, we focus on MCH’s role …

Decoding Affective Information From Neuronal Populations In The Human Hippocampus, Alexander N. Lawriw

LSU Master's Theses

The hippocampus is understood to play a key role in the formation of episodic memories. Prominent theories suggest this is made possible through use of sparse encoding schemes, in which a small number of neurons encode each episodic event using a distinct pattern of neuronal activity. However, more recent computational models suggest that the hippocampus may also be capable of representing semantic structure, a notion previously thought to be exclusive to the neocortex. In our previous line of work, we trained multivariate classifiers to predict the semantic content, specifically affect, of computer-generated faces given spiking data taken from individual neurons …

The Fibromyalgia Pain Experience: A Scoping Review Of The Preclinical Evidence For Replication And Treatment Of The Affective And Cognitive Pain Dimensions, Cassie M. Argenbright, Alysia M. Bertlesman, Izabella M. Russell, Tracy L. Greer, Yuan B. Peng, Perry N. Fuchs

Psychological Science Faculty Publications

Fibromyalgia is a chronic, widespread pain disorder that is strongly represented across the affective and cognitive dimensions of pain, given that the underlying pathophysiology of the disorder is yet to be identified. These affective and cognitive deficits are crucial to understanding and treating the fibromyalgia pain experience as a whole but replicating this multidimensionality on a preclinical level is challenging. To understand the underlying mechanisms, animal models are used. In this scoping review, we evaluate the current primary animal models of fibromyalgia regarding their translational relevance within the affective and cognitive pain realms, as well as summarize treatments that have …

Take A Closer Look: Combating Ageism Through The Use Of Children's Literature, Janice Buehrer

Honors Projects

This project was completed as my final honors project for Bowling Green State University in the spring of 2024. I wrote and illustrated the children's book, "Take a Closer Look," designed for kindergarten through second-grade children. The goal of the book is to be used as a value-socialization device to instill positive perspectives on aging within younger generations. The book itself is meant to be an intergenerational tool as adults read the book about older adults to children, reaching the entire lifespan.

Resting-State Functional Connectivity Correlates Of Inhibitory Control Over Emotional Stimuli, Makayla Mattson

All NMU Master's Theses

Inhibitory control is defined as the stopping or overriding of a mental process with or without intention. It is known as a motor process in which executive control suppresses an automated motor response. Currently, there is no existing research discussing the neural mechanisms of an emotional anti-saccade task, therefore with the use of resting-state functional magnetic resonance imaging (fMRI) and an emotional anti-saccade task, this study aims to identify the neural correlates of inhibitory control over emotional stimuli. The anti-saccade task is known as an effective measure of inhibitory control since it requires inhibiting a reflexive response and re-orienting attention …

Focus Group And Survey Responses To Postural Feedback During Creative Movement Exploration, Mary C. Matthews

Senior Theses

John H. Riskind’s “appropriateness hypothesis” states that posture, positions, and gestures can be emotionally self-regulating if an individual holds a posture that is appropriate for its context. A litany of studies on power posing suggests expansive postures could increase Feelings of Power. One meta-analytic review demonstrates the “robust” significance for evidence of “power feelings, emotion, or self-esteem” due to postural feedback while cautioning researchers on the empirical invalidity of evidence for behavioral and physiological variables. A qualitative description of individuals’ experiences as they change posture, gesture, and position would direct future research on postural feedback. The current project qualitatively examines …

Empowering Environmental Education In Portuguese Primary Schools: Energy Focused Curriculum Recommendations And Behavioral Change Framework Guided By Principles Of Developmental Psychology, Ellie Hanson

Independent Study Project (ISP) Collection

This paper explores the integration of principles of developmental psychology within the context of environmental education in Portugal to promote pro-environmental behavior, and specifically energy literacy energy conservation behaviors in primary school students. A review of current literature on the state of environmental education approaches in Portugal exhibits a significant lack of structure and direction for educators to teach students relevant topics in sustainability. Using a meta-theory of behavioral change, the present work connects the elements of the COM-B model of behavioral change to relevant aspects of middle childhood cognitive development using principles of two major theories of developmental psychology. …

Winners And Losers: Emotional Shifts Across Elections Are Conveyed By A Politician’S Smile, Carl Senior, Patrick A. Stewart, Erik Bucy, Nick Lee

Political Science Faculty Publications and Presentations

The human smile can convey both rewarding and affiliative social intent and thus has significant utility in politics, where the ability to bond with and reassure voters is vital to electoral success. We examine experimental evidence from the 2019 UK general election to investigate the influence of a politician’s reward or affiliative smile on voter emotions. It was hypothesised that the winner’s affiliative smile would engender positive affect across all partisan groups compared to the winner’s reward smile display. Participants from a nationally representative sample were shown campaign footage containing both types of smiles from the leaders of the main …

Evaluation Of Dietary Probiotic Supplements On Methamphetamine-Induced Impulsive Action In Rats Maintained On A Differential Reinforcement Of Low Rate Schedule, Kaitlyn Steck

Masters Theses

Substance Use Disorder (SUD) is a chronic, debilitating condition often comorbid with anxiety and depression. Both SUD and affective disorders are characterized by cognitive dysfunction, including impaired decision-making and impulsivity. A mounting body of research implicates gut microbiome alterations as a contributing factor to the pathophysiology of affective disorders. No published studies have assessed behavioral effects of dietary interventions targeting psychostimulant-induced gut microbiome changes. The present study utilized a differential reinforcement of low rate responding schedule (DRL 18 s) as a behavioral index of drug-induced impulsive action to determine if a dietary probiotic supplement alters the behavioral effects of (+)-methamphetamine …

Personality Linked To Tv Genres, Kinsey P. Skinner

Honors Theses

The goal of this study was to consider the relationship between people’s personalities and their television preferences. One model for this study was the work of Samuel Gosling from UT- Austin. Gosling has explored connections to personality from the mundane, such as music. To do this research in relation to television, students at Texas A&M University-Commerce completed the Big Five personality inventory as well as rating their interest in different genres of television, reporting on their favorite shows, and providing basic demographic variables. From this, correlations were found between certain personality traits and what television shows they are associated with. …

Does The Number Of Individuals Present In The Water Affect Dolphin Activity Levels, Erika Aguirre, Xavier Castillo, Quinn Gallagher

Posters - 2024

Bottlenose dolphin behavior and complex social structures have interested humans over the years. Dolphin deviation in these behaviors has been measured many ways such as activity levels, space used, and time of day. A study was focused on dolphin interactions with humans, patterns of lagoon space utilization, and temporal factors. Data have been collected at the Roatán Institute for Marine Sciences (RIMS), which houses a diverse sample of 16-18 dolphins. No correlation was observed between increased human presence and levels of dolphin activity. Dolphins did display higher preferences for specific lagoon areas. This variability in lagoon space utilization suggests an …

Assessing Bottlenose Dolphin (Tursiops Truncatus) Behavioral Responses To Discriminative Stimulus During Dolphin Interaction Programs (Dips), Megan Davis, Hannelore Tampipi

Posters - 2024

Dolphin-human interaction programs (DIP) References have become a popular experience offering humans an opportunity to interact or swim with cetaceans, most often bottlenose dolphins (Tursiops truncatus).

● Previous studies on dolphin-human interactions have been centered on therapeutic results for humans (Brensing et al., 2005), guests’ future conservation efforts, and educational efficacy (Miller et al., 2013) rather than welfare or outcomes for dolphins (Smith, 1981).

● Under human care, trainers request behaviors from dolphins typically via a hand signal as a discriminative stimulus (SD).

● Resulting behavioral responses to these SDs during interaction programs may suggest willingness to participate (WTP), and …

Comparing Activity Levels Of Bottlenose Dolphins (Tursiops Truncatus) During Snorkels To A Swimming Researcher, Sabrina Drouin, Erika Aguirre, Charles Lares

Posters - 2024

Bottlenose dolphins under professional care are provided with a range of enrichments that have a variety of features and levels of complexity at various frequencies (Lauderdale et al., 2022). In a previous study conducted by Brensing et al. (2015), they found that dolphins seemed to be attracted to adult swimmers, but only if they had ample space to swim. The purpose of this study is to examine dolphin activity level under two different conditions with humans in the water. We hypothesize that dolphin activity level will be higher during snorkel sessions than a single swimming researcher because there are more …

A Descriptive Study Of Baseline Activity Levels Of Tursiops Truncatus, Brianna M. Erck

Posters - 2024

Well-being of bottlenose dolphins (Tursiops truncatus) has been measured in many ways, including activity levels. Activity levels are composed of behaviors that vary with intensity and range from floats, breaches, perimeter swims, and aerials. Deviations from baseline behavior or activity level may be indicative of changes in state of well-being. The purpose of this study was to assess the activity level of a large social grouping of bottlenose dolphins in human care during baseline observations. A total of 215 5-min observation sessions were collected for a population of 15 to 18 bottlenose dolphins located in Roatán, Honduras between 2019-2024. The …

How Do Bottlenose Dolphins (Tursiops Truncatus) Behave In The Presence Of A Swimming Researcher?, Brianna M. Brianna, Megan E. Davis

Posters - 2024

Longitudinal observations of bottlenose dolphins (Tursiops truncatus) in managed care provide opportunities to assess behavior within different contexts, which may provide insights into individual and population wellbeing (e.g., Delfour et al., 2021; Serres et al., 2021). Since 2019, a longitudinal study on space use by bottlenose dolphins housed at a lagoon-based facility in Roatán, Honduras, has been conducted. Dolphin behavior and location data were collected with the goal of comparing behavior without humans present to varying contexts in which humans were present. The purpose of this descriptive study was to assess behaviors exhibited by dolphins in close proximity to a …

A Comparison Of The Relative Magnitude Of Combinations Of Relapse Types In Rats, Mary Bridges

Theses

Applied behavior analysis uses scientifically derived methods to create treatments for socially significant behaviors. A threat to these successful treatments is the recurrence of previously reduced behavior (i.e., relapse). Relapse can be categorized into several types depending on the variables that induce relapse. Three types prevalent in clinical settings are reinstatement (i.e., induced by re-exposure to reinforcers or stimuli paired with the target behavior), renewal (i.e., induced by changes in context), and resurgence (i.e., induced by worsening of alternative reinforcement). Because relapse is harmful to long-term treatment maintenance, prior research has developed and tested mitigation strategies for these relapse types, …

Paul Celan And The Processes Of Survival In Post-Shoah Jewish Writing, Ari Savage

Theses

The following is a study of the poetry of Paul Celan as a representation of psychological and social processes present in the written works of Shoah survivors. It begins with an analysis of the place of writing in Jewish culture, then identifies three primary processes which operate in sequence: alienation, individuation, and integration. By examining Paul Celan’s highly personal and autobiographical texts in the context of his life experience as a Shoah survivor it is possible to discern the social and psychological forces at work which compel survivors to express their traumas in written form, and to gain a better …

The Experiences Of Multilingual Learning-Focused School Counselors: A Phenomenological Investigation, Chelsea Jo Hilliard

Counseling & Human Services Theses & Dissertations

Equity in education has become increasingly prioritized, due to the growing mainstream recognition of the inequitable practices that historically have and presently continue to exist in K-12 education. With the K-12 student population diversity continuously increasing in areas such as abilities, race/ethnicities, socioeconomic status, languages, immigration status, and more, ensuring equitable access to education is vital. One such unique student group needing equitable access to education are multilingual learners or MLL. Located within schools, school counselors are uniquely positioned to equitably serve MLL students. Overall, while the research on school counselors serving MLL students (at the pre-service and practice level) …

Examining The Effects Of Social Group Persecution And Traumatic Humiliation In Survivors Of Torture, Tilda Cvrkel

Clinical Psychology Dissertations

Refugees and asylum seekers account for 34.4 million people worldwide (UNHCR, 2021), and up to 40% of this population are survivors of torture (UNHCR, 2017). The Istanbul Protocol (United Nations, 2022) describes one of the explicit ends of torture as the severing of a person from their community, a breaking of their dignity and humanity. This may be done explicitly, through acts of traumatic humiliation. Traumatic humiliation includes acts such as forcing victims to eat religiously forbidden food, forced posing or touching others in culturally taboo sexual ways, forced nudity or clothing that reflects misgendering (such as “emasculating” clothing), widespread …

The Influence Of Texting On Perceived Warmth: The Role Of Punctuation And Emoji, Elizabeth Mathews

Senior Honors Theses

Technology Mediated Communication (TMC) has become an essential part of interpersonal communication. Punctuation and emoji are major vessels of nonverbal communication in texting. The impact of punctuation and emoji use on perceptions of warmth was tested with 291 residential undergraduate students at Liberty University who were at least 18 years old. Through an online questionnaire, participants read a series of text messages with a randomly assigned condition of having either punctuation and emoji, punctuation and no emoji, no punctuation and emoji, or no punctuation and no emoji. Results indicated a significant main effect for the presence of emoji on perceived …

BACKGROUND: Stress and depression have a reciprocal relationship, but the neural underpinnings of this reciprocity are unclear. We investigated neuroimaging phenotypes that facilitate the reciprocity between stress and depressive symptoms.

METHODS: In total, 22 195 participants (52.0% females) from the population-based UK Biobank study completed two visits (initial visit: 2006-2010, age = 55.0 ± 7.5 [40-70] years; second visit: 2014-2019; age = 62.7 ± 7.5 [44-80] years). Structural equation modeling was used to examine the longitudinal relationship between self-report stressful life events (SLEs) and depressive symptoms. Cross-sectional data were used to examine the overlap between neuroimaging correlates of SLEs and …

Readiness Of Nociceptor Cell Bodies To Generate Spontaneous Activity Results From Background Activity Of Diverse Ion Channels And High Input Resistance, Jinbin Tian, Alexis G Bavencoffe, Michael X Zhu, Edgar T Walters

Faculty, Staff and Student Publications

Nociceptor cell bodies generate "spontaneous" discharge that can promote ongoing pain in persistent pain conditions. Little is known about the underlying mechanisms. Recordings from nociceptor cell bodies (somata) dissociated from rodent and human dorsal root ganglia have shown that previous pain in vivo is associated with low-frequency discharge controlled by irregular depolarizing spontaneous fluctuations of membrane potential (DSFs), likely produced by transient inward currents across the somal input resistance. Using mouse nociceptors, we show that DSFs are associated with high somal input resistance over a wide range of membrane potentials, including depolarized levels where DSFs approach action potential (AP) threshold. …

Calcific aortic stenosis can be considered a model for geriatric cardiovascular conditions due to a confluence of factors. The remarkable technological development of transcatheter aortic valve replacement was studied initially on older adult populations with prohibitive or high-risk for surgical valve replacement. Through these trials, the cardiovascular community has recognized that stratification of these chronologically older adults can be improved incrementally by invoking the concept of frailty and other geriatric risks. Given the complexity of the aging process, stratification by chronological age should only be the initial step but is no longer sufficient to optimally quantify cardiovascular and noncardiovascular risk. …

Identity-Driven Targeted Violence: Attending To Identity, Emotion, And Personality-Related Predictors Of Attitudinal And Behavioral Prejudice, Patrick Timothy Mcgonigal

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Identity-driven targeted violence driven by gender identity, sexuality, race, and religion overwhelmingly impacts marginalized groups of individuals. Existing evidence suggests that acts of bias on college campuses are often unreported by students, leaving those who engage in these behaviors to continue without proper redress. A great wealth of data illustrates the deleterious impacts of identity-driven behavior on student victims, including heightened psychological distress, poorer academic performance, and lower retention. In contrast, limited research has examined relevant underpinnings of perpetrating identity-driven harassment. The current dissertation developed and disseminated a large survey to undergraduate students spanning three years of data collection. The …
