How Schema Knowledge Affects Memory, Sarah Waller

Psychological Science Undergraduate Honors Theses

Schemas are a type of semantic knowledge that are formed from generalizations about the world. Schemas are essentially expectations about how we expect the world to be, and they are helpful for understanding and categorizing information we encounter. Prediction errors, which occur when our predictions are violated, are caused by events that are inconsistent with our schemas. Current findings on prediction error’s effects on memory are contradictory, with some studies stating that the presence of a prediction error enhances memory for a context, while other research disagrees. A popular theory proposes that prediction error causes a boost in memory for …

Agritourism Marketing Communications: An Analysis Of Practices And Challenges In Arkansas, Kyla Paige Moseley

Graduate Theses and Dissertations

Agritourism is seen as an avenue for operators as another channel of income, as well as a way for the visitors to learn about and experience agriculture. Marketing communication is needed by these operations to be visible to their communities. However, there is limited literature on agritourism marketing communications practices and challenges, especially in Arkansas, and on the use of word of mouth (WOM). This study aimed to fill that gap and provide practical recommendations to agritourism operators, extension offices, and the Arkansas Agritourism Association (ArAA) on how to better market operations. Using semi-structured interview questions, ArAA operators were asked …

Detection Of Changes In Short Narratives, Presley Priddy

Psychological Science Undergraduate Honors Theses

Narrativity and object association have been extensively researched in the past to determine how changes in a text impact reader interpretation. In this research, we attempted to establish a relationship between the relation of an object to a character situated in a particular narrative context and the detection of inconsistencies presented in the given story. Participants read texts that either associated or dissociated an object with a character, within a high or low-narrative context. Reading times were measured on critical sentences that were inconsistent with the placement of previously dissociated objects. When presented with object inconsistencies in highly narrative stories, …

Sex Differences In How Celebrity Crushes Bolster Self-Perceived Mate Value, Madyson M. King

Psychological Science Undergraduate Honors Theses

Previous research indicates that parasocial relationships provide surrogate connections for individuals to where they offer various psychological benefits. Some benefits include self-esteem and improved body image, which may be connected by such relationships facilitating attainment of one's ideal self. Given this benefit of social surrogacy, it could be possible that a vicarious romantic connection with a parasocial figure may similarly bolster one's mate value if that relationship were to move an individual closer to a personal ideal. We predicted that engagement with a celebrity crush would be associated with a heightened mate value. A community sample of men and women …

Negation And The Backfire Effect, Caden Fowler

Psychological Science Undergraduate Honors Theses

Quick! Do not think of a polar bear. Did you think of a white bear? As Russian author Fyodor Dostoevsky wrote in his 1863 essay “Winter Notes on Summer Impressions,” “[when tasked to not think of a polar bear] you will see that the cursed thing will come to mind every minute.” The consequence of negation without context (i.e., unlicensed negation; Levine & Hagaman, 2008) is what has come to be referred to as the “backfire effect,” a phenomenon where correcting misinformation strengthens belief in that information rather diminishing it (Ecker, et al., 2020). Fake news and misinformation in …

The Effects Of Cannabidiol (Cbd) On The Social, Cognitive, And Physical Facets Of Anxiety Sensitivity, Ezri Rathbun

Psychological Science Undergraduate Honors Theses

The current study investigated how repeated administration of 300mg of cannabidiol (CBD), when compared to a placebo, affects the social, cognitive, and physical facets of anxiety sensitivity (AS), a characteristic that reflects fear of the consequences of anxious arousal. Prior work suggests CBD may have anxiolytic effects that may be specific to the social aspects of anxiety. Thus, it was hypothesized that, that, relative to placebo, CBD would reduce self-reported AS-social concerns, but not AS-cognitive or AS-physical concerns, compared to baseline. Participants (N= 79; 52 women; M_age = 22.06) with elevated perceived stress were randomly assigned to 14 …

What Are The Roles Of Vocabulary And Working Memory In Metaphor Comprehension?, Claire Simpson

Psychological Science Undergraduate Honors Theses

One of the most notable factors that influence sentence comprehension is the presence of metaphors (e.g., Inhoff, Lima, & Carroll, 1984). The metaphor interference effect (MIE) is a very interesting result of metaphor comprehension. It is a well-known linguistic effect (e.g., Al- Azary et al., 2021; Glucksberg et al, 1982) that can result in participants taking longer to determine that a metaphoric statement is false compared to other non-metaphoric literally false statements. The present study investigated the impact that vocabulary knowledge, working memory capacity, and memory load have on the metaphor interference effect. We predicted that each of these characteristics …

The Effect Of Self-Disclosure To Dogs On Stress, Coping, And Emotional Well-Being, Lilian Crawford

Psychological Science Undergraduate Honors Theses

Self-disclosure has been defined as the voluntary sharing of personal thoughts and experiences with another individual, and in recent years, it has been associated with improvements in psychological and physiological well-being. Recent research into animal-assisted therapy has also demonstrated the emotional benefits of interacting with dogs. However, the current research has not yet explored how the specific act of self-disclosure to dogs affects emotional well-being. The present study explored the effects of self-disclosure to dogs on stress, ability to cope, and emotional well-being. Participants (N = 113) included dog owners who were randomly assigned to one of three conditions: self-disclosure …

Religious Extremism & Courtroom Cooperation: Examining Variability In Terrorism And Religiosity, Amanda P. Hux

Sociology and Criminology Undergraduate Honors Theses

While prior studies have investigated the impact of religion on terrorism, our study specifically aims to inform the literature of religious affiliation's effect on a defendant's propensity to plead guilty. Our study uses data from the American Terrorism Studies (ATS) database from the University of Arkansas’s Terrorism Research Center. The study focuses on twelve variables in relation to pleading guilty, gender, categories of terrorism, race, and ethnicity. Crosstabulation and Binary Logistic Regression were used to analyze the subset “Offender” within the ATS. Three hypotheses were reviewed, finding that religious affiliation has a positive correlation with a defendant’s propensity to plead …

Fantasies Of Just Torture: On Violent Efforts To Navigate The Intolerable, Tonya Sims

Philosophy Undergraduate Honors Theses

This thesis examines why torture, despite being among the clearest objects of moral revulsion available to us, remains imaginable as a serious moral possibility. I begin by refining the concept of torture through an examination of the United Nations Convention Against Torture, while arguing that insufficient attention has been paid to what I take to be its paradigmatic form, namely sadistic torture. Against definitions that treat torture primarily in instrumental terms, I argue that torture is best understood as the intentional infliction of extreme pain upon an unwilling person in order to dominate or otherwise manipulate their autonomy. Drawing on …

The Effect Of Including A Yeast Culture Containing Essential Oils In Receiving Cattle Diets On Growth Performance And Health, Taylor Deanna Foster

Animal Science Undergraduate Honors Theses

Due to the increased risk of bacterial populations developing resistance to current antibiotics, consumer perceptions surrounding the utilization of antibiotics use in cattle, and the endemic incidence of bovine respiratory disease (BRD) among growing and finishing cattle, alternative management strategies to improve the health of cattle must be developed. The objective of this study was to evaluate the use of a supplement containing a yeast culture and an essential oils blend (YEO) on the health and growth performance of stocker calves at high-risk for BRD. Crossbred male beef calves (n = 185) received on two separate dates were used in …

Cultural Authenticity And Commercialization: The Journey Of Southwest Indigenous Jewelry, Kaytlin M. Dwyer

Anthropology Undergraduate Honors Theses

Introduction Today, Southwest Indigenous jewelry exists at the intersection of cultural expression and commercial exchange. Drawing on interviews with Native artists, this study focuses on the lived experiences of those who design, produce, market, and curate Indigenous jewelry to argue that authenticity is not defined by visual appearance alone, but by the cultural knowledge, community relationships, and generational practices embedded in each piece. As Native silversmiths navigate increasing pressures from mass production, appropriation, and global markets, they actively work to maintain both artistic integrity and cultural authenticity. At the same time, this paper explores the tension between appreciation and appropriation. …

Developing Warning Signage For Harmful Algal Blooms At Lake Fayetteville, Abigail R. Evans

Biological Sciences Undergraduate Honors Theses

The presence of harmful algal blooms (HABs) poses many risk factors for human health, and once microcystin concentration has reached a certain level, that water source will be closed for the duration of the bloom. Agencies tend to use static signage with limited information to inform the public about the current status of the water, but a sign similar to the one used by the National Fire Danger Rating System can allow for constant updates detailing specific risk levels for the public. Using previously reported data on Lake Fayetteville, thresholds for risk factors that are easily measurable were determined. The …

The Genetic Basis Of High Transformation Efficiency In The Model Yeast Saccharomyces Cerevisiae, Mary Kathryn E. Cheek

Biological Sciences Undergraduate Honors Theses

Transformation, a type of horizontal gene transfer, describes the uptake, maintenance, and integration of environmental DNA by cells. Despite the known effects of transformation on evolutionary processes, little is known about the genetic basis of this phenomenon. Saccharomyces cerevisiae is a eukaryote able to transform at quantifiable rates when made chemically competent and treated with a heat shock. S. cerevisiae also has variation in transformation efficiencies between various strains, and high recombination rates allow for sufficient allele “shuffling” in intercross populations. This project utilizes a bulk segregant analysis approach to compare sequencing data between transformant pools and non-transformant pools of …

Cross-Facility Reliable Deep Learning Based Beef Marbling Assessment Via Unsupervised Domain Adaptation Regression, Samuel Vinson

Biological and Agricultural Engineering Undergraduate Honors Theses

Inconsistent quality grading in beef production leads to inefficiencies, economic disparity, and consumer mistrust. While USDA meat grading traditionally relies on skilled visual inspectors, these human evaluations suffer from cross-facility variability and subjectivity. This paper introduces the first known application of unsupervised domain adaptation regression for cross-facility beef marbling score prediction—an innovation that improves generalization across diverse environments in the beef supply chain. Utilizing numerical scores ranging from 100-900, the research employed convolutional neural networks (CNNs), including ResNet, VGG, and AlexNet architectures. The study specifically introduced and validated a unified unsupervised domain adaptation regression method using the ResNet-50 architecture to …

Preserving The Past: Exploring The Last Frontier's Ecosystem Shifts And Biodiversity Of The Tallgrass Prairies, Gisell Maldonado, Amelia Villaseñor

Anthropology Undergraduate Honors Theses

In North America, grasslands are a cornerstone of the environment. Historically, the tallgrass prairie was expansive and reached from Manitoba in Canada to Texas. Today this unique ecosystem is highly fragmented and reduced, but it remains an important ecosystem for biodiversity and cattle management. While there are many complex ecological interactions in the prairie, recent research shows that large herbivores are vital in maintaining grasslands through grazing and other behaviors that reduce woody encroachment and support nutrient cycling. Here, we examine cow and bison dietary behaviors and connect these to the ecosystem services provided by these large herbivores. In the …

Primate Craniofacial Trauma And Its Relationship To Socioecological Factors, Kaitlyn Harden R. Harden

Anthropology Undergraduate Honors Theses

Postmortem analysis of the skeleton can reveal patterns of trauma that have accumulated over an individual’s lifetime. Patterns of trauma within a species can also provide key insights into how that species lived and reflect aspects of their socioecology and life history. Research has been conducted often on postcranial trauma, but is rare regarding the craniofacial region and has not been examined broadly across primates. To fully understand patterns of trauma in primates, rates of trauma must be compared and placed into context of a variety of socioecological factors. To do so, I examined hypotheses including that species with higher …

No Place But Here, Dillon Bryant

Graduate Theses and Dissertations

The writing in this document is a dovetailing of fragments ranging from critical inquiry, analysis, scripts, and other observations that relate to the body of work in “No place but here”. It is an accompanying document attempting to enrich the visual work rather than a direct illustration. The installation of “No place but here” at the Rogers Creamery is an investigation utilizing collage, text, and other constructed photographs, images, and objects to play with and against familial and broader narratives of power, control, and ambiguity associated with the American West. Underpinned and intersected by interior questions revolving around artifice, connection, …
