Testing The Impact Of Prebiotics On Anxiety-Like Behaviors In Aged Male Rats, Nicholai Shaw, Marny Ehmann, Kenia Urena-Gonzalez, Anna Langholz, Peter Stewart, Jared Stygstra, Emily Zolman, Erin English, Alli Lindquist, Elizabeth Woodford

18th Annual Celebration of Undergraduate Research and Creative Activity (2019)

The composition of gut microbiota has direct impacts on neural structure, neurochemistry, and behavior. Specifically, the gut microbiota has been shown to modulate anxiety-like behaviors. In addition, administering prebiotics, compounds that promote the growth of commensal bacteria, has been demonstrated to reduce anxiety and anxiety-related behaviors. However, this effect has yet to be tested in older animals despite anxiety being implicated as a most common disorder in adult populations. Therefore, this study seeks to fill this knowledge gap by investigating the link between prebiotic interventions and anxiety-like behaviors in aged populations. It was hypothesized that older rats treated with the …

The Serial Blocking Effect: A Testbed For The Neural Mechanisms Of Temporal-Difference Learning, Ashraf Mahmud, Petio Petrov, Guillem R. Esber, Mihaela D. Iordanova

Publications and Research

Temporal-difference (TD) learning models afford the neuroscientist a theory-driven roadmap in the quest for the neural mechanisms of reinforcement learning. The application of these models to understanding the role of phasic midbrain dopaminergic responses in reward prediction learning constitutes one of the greatest success stories in behavioural and cognitive neuroscience. Critically, the classic learning paradigms associated with TD are poorly suited to cast light on its neural implementation, thus hampering progress. Here, we present a serial blocking paradigm in rodents that overcomes these limitations and allows for the simultaneous investigation of two cardinal TD tenets; namely, that learning depends on …

Using Animal-Assisted Therapy To Treat Children With Autism Spectrum Disorder, Mary Strong

Student Research Symposium

This paper looks at the studies of the relationship between those with autism spectrum disorder and therapy animals in order to determine how effective therapy animals are in reducing problem behaviors and increasing social interaction. For this literature review, nine different studies have been reviewed to answer the research question over a variety of settings. In the nine different studies that were reviewed the animals used were either dogs, horses, or guinea pigs. These studies were used to determine which of these animals were more effective in a therapeutic setting, and more effective in the improvement of the symptoms in …

Assessment Of Mglur5 Ko Mice Under Conditions Of Low Stress Using A Rodent Touchscreen Apparatus Reveals Impaired Behavioural Flexibility Driven By Perseverative Responses, Jisoo Lim, Eosu Kim, Hyun Jong Noh, Shinwon Kang, Benjamin U. Phillips, Dong Goo Kim, Timothy J. Bussey, Lisa Saksida, Christopher J. Heath, Chul Hoon Kim

Brain and Mind Institute Researchers' Publications

© 2019 The Author(s). Genetic and pharmacological manipulations targeting metabotropic glutamate receptor 5 (mGluR5) affect performance in behavioural paradigms that depend on cognitive flexibility. Many of these studies involved exposing mice to highly stressful conditions including electric foot shocks or water immersion and forced swimming. Because mGluR5 is also implicated in resilience and stress responses, however, apparent impairments in inhibitory learning may have been an artifact of manipulation-induced changes in affective state. To address this, we present here a characterization of cognitive flexibility in mGluR5 knockout (KO) mice conducted with a rodent touchscreen cognitive assessment apparatus in which the animals …

Delay Discount Rate Moderates A Physical Activity Intervention Testing Immediate Rewards, Christine B. Phillips, Jane C. Hurley, Siddhartha S. Angadi, Michael Todd, Vincent Berardi, Melbourne Hovell, Marc A. Adams

Psychology Faculty Articles and Research

Financial incentives can increase physical activity (PA), but differences in the immediacy of reward delivery and individual differences in delay discount rates (i.e., higher discount values associated with less tolerance for delayed rewards) may explain differential responding. The current study tested whether delay discount rate moderated the relative effectiveness of immediate financial rewards on increasing daily PA. Inactive, overweight adults (ages 18–60, N = 96) were randomized to receive either smaller, immediate goal-contingent rewards or larger, delayed rewards for participation. Delay discount rates were derived for those who completed the Monetary Choice Questionnaire (N = 85). Linear mixed models tested …

Palatable Shades Of Gender: Status Processes At The Intersections Of Race, Gender, And Team Formation, Jasmón L. Bailey

USF Tampa Graduate Theses and Dissertations

This dissertation addresses the importance of studying how race and gender influence partner selection processes of team formation. Stratified social systems influence the choice and decision-making behaviors that shape group and team formation (Hechter 1978). By testing Skvoretz’s and Bailey’s (2016) formal theory of team formation choice processes derived from expectation states theory, the dissertation aims to understand how race and gender influence a person’s choice and decision-making with respect to forming a group of problem-solving teammates. Through a quasi-experimental research design, subjects participate in simulated interactive environments in which they can select and personalize self-represented avatars and then choose …

The Roles Of Race And Gender In Contagious Yawning, Daroon Jalil

James Madison Undergraduate Research Journal (JMURJ)

Social psychologists often consider race to be a marker of in- or out-group status. When looking at race, implicit bias can take more subtle forms than outward racism. This study asked two research questions to better understand the psychology behind racial issues. The first question was whether the number of contagious yawns (CY) a person experiences depends on the race of the stimuli being viewed. Yawning more in response to in-group members is a phenomenon seen in chimpanzees, but it has not been studied in humans in a racial context. Black and white males and females were recruited to view …

Evolutionary And Social Manifestations Of Misled Fear: How Fear Motivates And Manipulates, Meghan Sink 19

Honor Scholar Theses

This thesis emphasizes the negative outcomes associated with misled fear. It begins by examining the evolutionary basis of human and animal fear, and then applies the fear learning process as well as evolutionarily innate fears to maladaptive cognitive and behavioral outcomes that manifest today. One example of such a maladaptive manifestation is a behavior based in racial prejudice, occurring from an act based in the evolutionary fear of an out-group. Finally, this paper presents how human fear is further misled and manipulated by the media--intentionally and unintentionally. Overall, the present argument is that humans must increase their conscious awareness of …

Sound And Emotion: The Use Of Music In The Cinematic Experience, Sarah Schulte

Mahurin Honors College Capstone Experience/Thesis Projects

To portray the radical importance of music in stimulating emotion within cinema, to appeal to an audience’s selective attention to sounds, and to detail the process of creating an original film score, I have scored WKU student Tori Mills’ short film Come Up for Air. Film music is traditionally defined as any music that accompanies a film, though today it more specifically refers to music intended to advance the film’s narrative. Music has played an increasingly important role in transmitting emotion to film audiences, feeding the psychological connection between spectator and on-screen action. To achieve this emotional connection, a film …

The Effects Of Message Matching In Climate Change Persuasion, Matthew R. Penner

Masters Theses & Specialist Projects

Public opinions of climate change are not consistent with the reality that climate change is occurring. Effective persuasive messages must be created to ensure that irreparable damage to the environment is prevented. This study investigated the cognitive processes that occur when an individual is exposed to a persuasive message regarding environmental concerns that is matched to an individual’s personality characteristics like right wing authoritarianism and purity.

Messages on two environmental topics (solar panels and the Environmental Protection Agency) were created. Each topic was framed in multiple ways to test hypotheses about personality-based message matching. Participants completed a thought listing task …

Perception: Exploring Cognition And Consciousness Through Visual Art, Summer Shepherd

Mahurin Honors College Capstone Experience/Thesis Projects

The concept of consciousness has perplexed humankind for thousands of years. Countless scientists, philosophers, and artists have devoted their lifetimes to solving humanity’s questions about our relationship with the world we live within. The creative arts, such as music, theater, and visual art, can facilitate critical thinking and meaningful interpersonal communication. This paper explores the visual artwork of the author, Sunny Shepherd, through examination of historical and contemporary artistic influences on the work, as well as the psychological and philosophical concepts that fuel it. Months of research, planning, and creating went into the manifestation of the final exhibition, Metamorphosis , …

The Impact Of A Therapist's Language In Computer-Mediated Communication, Robert E. Twidwell

Masters Theses & Specialist Projects

Background: Nearly 45 million adults in the United States live with a mental health disorder and only 43% of them seek treatment. One of the major barriers to seeking treatment is accessibility and can be addressed through telepsychology, or providing services with technology. With technological improvements in written communication, using computer-mediated communication (CMC; e.g. text messaging) has become more regularly used and examined in healthcare. To date, little research has focused on the use of practitioner language in telepsychology.

Method: Two samples (university sample and national sample) totaling 396 participants were asked to rate a therapist on attractiveness (i.e. likability …

Forensic Social Work: Interviewing Sexually Abused Children, Maleaha F. Davis

Selected Honors Theses

In the United States, each year, there are at least one million cases of child sexual abuse and even more cases that were not reported. For the cases that are reported, the child will meet with a social worker or other professional for a forensic interview. The goal of a forensic interview is to explore claims or suspicions of sexual abuse. The sexually abused children who participate in these interviews have already been traumatized and may not want to disclose. Yet the job of the interviewer is to elicit forensically sound information and details about the events from the children …

Serial And Concurrent Response Presentation: Their Effects On Resurgence, Michael P. Kranak

Dissertations

Serial response training (SRT) may mitigate resurgence of a target response when compared to teaching a single alternative response. However, the necessity of the serial presentation of alternatives is yet to be determined. We hypothesized teaching alternative responses at the same time (concurrent response training [CRT]) may be as effective as, and more efficient than, SRT. We used a multielement design embedded within an ABC resurgence arrangement in a human operant arrangement in three studies. Twenty-seven undergraduate students enrolled in a psychology course participated. In Study 1, we compared CRT to differential reinforcement of a single alternative response (traditional DRA). …

Children's Literature As A Catalyst For Social Change, Lyndsey Reynolds

Senior Theses

This thesis is the amalgamation of a creative writing project and an exploration of the ways that children’s literature influences and draws from social justice causes. It started after reading Good Night Stories for Rebel Girls and realizing that children’s books are not as simple as I remember them being. This book inspired me to consider the power of children’s literature to push young readers to be aware of and thoughtfully engaged with political, social and cultural conversations. The first phase of my thesis was exploring the relationship between social justice and children’s books by reading scholarly materials. In these …

Reintegration Of Women Perpetrators In Post-Genocide Rwanda, Terrie Soule

Independent Study Project (ISP) Collection

Women tend to be victims during times of violence. Due to this the breadth of research on women who perpetrate violence is limited. Due to stereotypes women are more often than not seen as peace makers and nurturers, which ignores the fact that women have just as much capability as men to inflict violence. During the Genocide against the Tutsi in Rwanda, average citizens, including women, became perpetrators of genocide. As this genocide only occurred in 1994 research on the reintegration of perpetrators is limited. This paper asks the question how are women perpetrators of Genocide being reintegrated into society? …

Task Specificity And Functional Outcome: What Is Best For Post-Stroke Rehabilitation?, Rachel Tomazin

Honors Projects

Stroke is a debilitating insult to the brain occurring from a blockage in blood supply (ischemic), or a bleed (hemorrhagic) in one hemisphere of the brain. Worldwide, approximately 10 million people are left with moderate to severe disability due to stroke; the most common deficit is upper extremity impairment. Current stroke rehabilitation strategies utilize task specific training of a skill, meaning one practices the specific skill they want to regain. However, it is possible that there are more generalized types of therapy that can be as effective in rehabilitating debilitated skills. The current study utilizes several skilled reaching tasks in …

Critical Embodied Praxis For Social Justice And Peace Educators: A Story Of Personal Transformation Through Analysis Of My Jewish And Settler Identities, Cara Michelle Silverberg

Capstone Collection

In this paper, I examine definitions of and relationships between violence, oppression, peace, liberation, and embodiment in the context of critical pedagogy in order to construct a theory of critical embodied praxis for social justice and peace educators. Considering the body to be a tangible vessel through which narratives and mechanisms of violence are expressed and maintained, I explore the potential of the body to be a vessel through which liberatory narratives may be generated and shared. After constructing a theory of critical embodied praxis, I illustrate this framework in action through a personal narrative that explores the intersections …

Spatial Analysis Of Exposure To Soil Heavy Metals, Oral Bioaccessibility And Risk Assessment In Houston, Texas, Tsai Shu Chu

Dissertations and Theses (Open Access)

Chronic exposure to heavy metals could lead to adverse health effects such as cancer, neurological development diseases and immunological diseases. The ingestion pathway has been considered the major exposure route for heavy metal contaminated soils. Heavy metals may be proportionally bioaccessible for the human body to absorb. There are no risk assessment studies done in Houston to evaluate health risks from exposure to heavy metals and no spatial analysis done yet. The aims of this dissertation are (1) to characterize 13 heavy metals: magnesium (Mg), vanadium (V), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), zinc …

Rapid Assessment Of Problem Solving For Kids (Raps-K), Hannah Perdew

Mahurin Honors College Capstone Experience/Thesis Projects

The Rapid Assessment of Problem Solving (RAPS) is a clinical assessment of verbal problem solving skills created by Dr. Robert Marshall and colleagues (Marshall, 2003). The assessment, originally developed for adults, is based on the well-known twenty questions game. The clinician administering the assessment chooses a target picture and the participant asks yes or no questions to eliminate incorrect answers and, eventually, identify the target picture. Question asking efficiency, indicated by the number of choices eliminated, is considered to reflect levels of cognitive functioning, specifically problem solving. Recently, the RAPS has been utilized with typically developing children and children with …

Prosecutorial Misconduct: Mass Gang Indictments And Inflammatory Statements, K. Babe Howell

Dickinson Law Review (2017-Present)

This Article examines inflammatory statements by prosecutors in the context of mass gang indictments. I contend that inflammatory remarks not only harm the justice system and defendants, particularly minorities, but also that, when prosecutors craft and repeat hyperbolic narratives about vicious gang wars, prosecutors may come to believe the narratives and become effectively blinded to the fact that these narratives are improper, unfair, and untrue. First, I review the professional rules, standards, and case law that prohibit. Then, drawing on press releases and trial transcripts from two mass gang indictments in New York City, I demonstrate how prosecution statements exaggerate …

Jim Jones: A Case Study In The Relationship Between Antisocial And Narcissistic Personality Disorders, Taylor Martin

Senior Theses

Ambiguity between some characteristics of Narcissistic and Antisocial Personality Disorders has caused difficulties in the accurate diagnosis of these disorders (Gunderson & Ronningstam, 2001; Burke, 2006), and some clinicians and researchers have suggested that this may reflect a lack of clinical utility in the current categorical model of diagnosing personality disorders (Livesley, 2001). This study identifies confounding factors in the concepts of NPD and ASPD as enumerated in the DSM-5 (APA, 2013) and DSM-IV-TR (APA, 2000). Concepts identified in independent research that may clarify some apparent similarities and assist in differentiating between the two disorders are discussed. Clarifying features of …

The Effects Of L. Rhamnosus Consumption On Male Long Evans Rat Anxiety-Like Behavior, Amanda Marie Schleper

Honors Theses

Adolescent stress in humans has been correlated with an increased likelihood of an individual to develop an alcohol use disorder later in life. Literature has demonstrated that rats subjected to adolescent stress tend to show an increased preference and consumption of ethanol. Adolescence is a critical time of development. The link between adolescent stressors and alcohol use disorders is not fully understood yet. This study examined the relationship between adolescent stress and alcohol consumption and preference in rats. Probiotics are bacteria with potential health benefits and have been well accepted as a dietary supplement. Literature shows that probiotics could decrease …

Developing Functional Analysis-Informed Interventions To Reduce Mouthing In Dogs, Mindy Waite

Master's Theses (2009 -)

In human populations, the most efficacious behavioral interventions are function-based, which first requires identification of the behavioral function. The gold standard for isolation of the behavioral function is the functional analysis, which has been effectively used for decades on human behavior. However, companion animals also engage in behavior considered problematic by their human owners. In domesticated dogs, mouthing is a common behavior displayed by young dogs and is considered problematic by many human families. Without efficacious interventions, undesirable behavior in companion animals may result in reduced welfare, relinquishment, or even euthanasia of the animal. The purpose of this study was …

Sailing Into The Storm, Joseph Trunzo

Applied Psychology Department Faculty Journal Articles

Before she even knew what was happening, he was already on her. He punched her in the face, smashed her head against the wall, and dragged her through the corridor by her hair. The pain was searing; the fear, overwhelming. When help finally arrived, after what seemed like an eternity, the damage had already been done. The effects of the beating were both physical and psychological. The onset of trauma, at first muted by shock, would soon unfold in ways unimaginable to her. Her illusion of safety was shattered. This was her job. She was this person’s caretaker, an authority …

Behavioral And Voltammetric Analysis Of Chronic Escitalopram Treatment To The Hiv-1 Transgenic Rat: Implications For Comorbid Hiv-1 And Clinical Depression, Adam R. Denton

Theses and Dissertations

HIV-1 infection is a serious condition affecting approximately 37 million individuals. Between 30% and 60% of seropositive individuals will develop symptoms of clinical depression. These individuals are five times more likely to commit suicide than non-seropositive clinically depressed patients. Dysfunction in serotonergic and dopaminergic transmission has consistently been implicated in the pathogenesis of depression. Specifically, dysfunction in the prefrontal cortex and in the nucleus accumbens core region have been shown to be underlying factors in the trajectory of depression. Given these underlying neurological features, the present research employed behavioral testing and electrochemical recording in an attempt to elucidate the therapeutic …
