Using Fluency-Building Approach To Increase The Knowledge And Fluency Of Signing With Preschool Teachers: A Pilot Study, Angel Jia Yiuen Tan, Bryan Wen Xiao Tang, Gray Atherton, Liam Cross, Bethan Mair Williams

School of Psychology

Keyword signing, an augmentative communication strategy, is known to promote language acquisition in young children, yet staff in educational settings often receive insufficient training, leading to low retention and usage rates. This pilot study examined the feasibility and impact of a Precision Teaching-based intervention designed to improve preschool teachers’ proficiency and fluency in Makaton signing. Eleven teachers from a mainstream preschool in North Wales, with limited prior training, participated in a six-week intervention involving fluency training with 238 Makaton signs. Pre- and post-intervention assessments measured knowledge acquisition, and post-intervention tests evaluated fluency through retention, endurance, and application. Results demonstrated significant …

Understanding The U.S. Maternal Healthcare System At The Intersection Of Asian American Birth Outcomes And The Model Minority Stereotype: A Literature Review, Sophia Hevel

University Honors Theses

This thesis aims to explore the maternal healthcare system in the United States as it pertains to Asian American birthing people, the ways in which their racial, ethnic, and cultural identities are interacted with within the U.S. Healthcare system, and subsequently the detrimental effects of the medical system's devaluation of culturally specific birthing and postpartum practices have on Asian American birthing experiences. This will be accomplished through an exploration of the United States' maternal healthcare system, or rather, its crisis; how Asian Americans navigate a system that has not been structured to support their specific needs; and lastly, a discussion …

Exploring Private And Governmental Interest In Bitcoin, Mina Khadem

Undergraduate Theses, Capstones, and Recitals

Regardless of one’s opinion, Bitcoin’s presence in the global economy is growing. However, Bitcoin’s emerging role and its implications are greatly under-researched, particularly in the context of government interest in Bitcoin. Nonetheless, increased private investment in Bitcoin and increased government interest in formally incorporating Bitcoin into existing economic systems, suggest a new development within the global economy that must be investigated. Through qualitative text analysis of pro-Bitcoin narratives presented in digital media platforms and official government policies and public statements, this thesis explores how private and government interest in Bitcoin is explained and framed within these contexts. This study finds …

Perception Of Emotion In Autism With Controlled Elicitation (Peace), Austin Gillespie, Rachel E. Dewald

Undergraduate Research Symposium Lightning Talks

It is possible that autistic people find it easier to socialize within their own peer group (Beaupré & Hess, 2006), by recognizing socio-emotional nonverbal cues, due to a shared neurodivergence. To assess this, it would be helpful for researchers to have a database of emotional stimuli, validated for use with autistic individuals. Unfortunately, this does not exist. This current study’s objective is to create such a database that evokes natural emotion, rated by autistic individuals to be used in future research. All participants completed the Alexithymia Scale (TAS-20) which measures the participants’ ability to identify and describe their own emotions …

Inflammaging And Cognitive Decline: A Brief Review Of The Chronic Low-Grade Neural Inflammation Hypothesis, Gage Pompa

Undergraduate Research Symposium Lightning Talks

This presentation reviews the chronic low‑grade neural inflammation hypothesis as a mechanism linking aging to cognitive decline. Inflammaging refers to persistent, low‑level inflammation that develops with age due to immune dysregulation in the absence of infection. In the brain, this process is often triggered by the accumulation of beta‑amyloid plaques and phosphorylated tau tangles. Microglia attempt to clear these proteins, but their prolonged activation releases inflammatory mediators that damage surrounding neurons. Over time, this sustained neural inflammation contributes to neurodegenerative conditions such as Alzheimer’s disease, Parkinson’s disease, Huntington’s disease, epilepsy, and psychiatric disorders including schizophrenia and major depression. Imaging markers …

Design And Validation Of A Bilateral, Multi-Site 3d-Printed Neuronal Implant For Rodent Electrophysiology, Homero Phelps, Jonathan V. Trinidad, Talha Soluoku

Undergraduate Research Symposium Podium Presentations

Neuronal electrophysiology implants are essential tools in neuroscience for recording brain activity and investigating neurological disorders. Our lab’s previous 3D-printed implant designs centered around a single-site, recording platform that was limited in adaptability, precision, and lacked in vivo validation due to lingering engineering malfunctions. To combat limitations and expand recording capabilities, this project aimed to design and validate a new implant capable of multi-site, bilateral recordings across both brain hemispheres, specifically targeting the hippocampus (CA1 and CA3) and anterior cingulate cortex (ACC), regions critical for learning and memory. Building on the Open Ephys ShuttleDrive model, the implant was redesigned using …

Creating A Data Processing Pipeline With Mne-Python, Lesly Vazquez, Ananda Liz Peixoto Couto

Undergraduate Research Symposium Posters

The UNLV Psychophysiology of Emotion and Personality Lab (PEPLab) utilizes a MATLAB based pipeline to process electroencephalogram (EEG) recordings. MATLAB is a proprietary software package, which limits the ability to analyze psychophysiological data and increases the financial burden of research. To increase the accessibility of data reduction skills, we have created and tested a new pipeline utilizing MNE-Python, an open source software package (Gramfort et al., 2013). In this pilot study, we utilized existing EEG recordings and examined the relationship between the Triarchic Model of Psychopathy and Error-Related Negativity (ERN) responses across incorrect and correct trials during a Letter Shock …

From Dante’S Inferno To California: Visualizing The Marginalized In Sandow Birk’S Social Critique, Lorenzo Williams

Undergraduate Research Symposium Posters

This research explores the intersection of medieval literature and contemporary visual art, focusing specifically on Sandow Birk’s reinterpretation of Dante Alighieri’s Divine Comedy. By examining Birk’s illustrated adaptations of Inferno and Purgatorio, this paper analyzes how he translates and visually reimagines Dante’s moral and spiritual journey as a modern critique of California’s social crises, particularly those affecting unhoused populations. It investigates Birk’s recontextualization of Dante’s allegory in relation to the urban decay of Los Angeles and San Francisco. Ultimately, this study aims to reveal how Birk’s visual narrative bridges historical understandings of religious and social issues with contemporary experiences of …

Prediction Error's Influence Of Declarative Memory: A Replication, Camila Schettini, Kevin Mohawk

Undergraduate Research Symposium Posters

We often have predictions about what to expect in our everyday encounters. However, not all these predictions will be accurate. Prediction error (PE) refers to the discrepancy between expectations and actual observed outcomes, and it is believed to play a role in learning, such as in classical conditioning. Yet, its relationship to one-shot declarative memory remains poorly understood. In the present study, we aimed to replicate Greve et al. (2017, Experiment 1) by testing whether PE enhances memory. Participants first learned scene-word associations in which a specific scene image was paired with one of two category labels, “positive” or “negative”. …

Examining The Relationship Between The Initial Level Of Learning And The Rate Of Forgetting, Lex De Asis, Justin Mykovich, Rhiannon N. Soriano Smith

Undergraduate Research Symposium Posters

It has been widely contested whether the rate of forgetting is connected to the initial degree of learning. While recent studies suggest that forgetting occurs at a consistent rate regardless of how well material was initially learned, other studies argue that this conclusion depends heavily on the analytical approach and the operational definition supplied. Additionally, emerging frameworks, such as the Representation Theory of Forgetting (Sadeh et al., 2014, 2016), propose that different brain regions support distinct types of memory representations, with each governed by separate forgetting mechanisms. This study seeks to examine how the degree of learning affects the rate …

Exploring Themes Of Gender And Nature Through An Ecofeminist Analysis Of Three Eco-Horror Films, Valeria Evelin Valdez Rios

Undergraduate Research Symposium Posters

With warmer days and more frequent natural disasters, it is clear to see climate change and global warming on the rise. It is more important now than ever to spread awareness about climate change’s consequences and how we can address them. Both nature and women are oppressed by patriarchal, capitalist systems, which is why we are interested in the intersection of gender and nature in environmental media. Our hopes are to tap into an under-studied field of environmental communication by analyzing eco-horror films, which are horror films with environmental messages. Using ecofeminist rhetorical theories, we analyze how three eco-horror films …

Undergraduate Research Symposium Posters

Eating disorders are a spectrum of cognitive, behavioral, and physical symptoms related to eating and compensatory weight management behaviors. Body image concerns can be a significant risk factor for various disorders, such as anxiety, depression and eating disorders. Additionally, eating disorders are commonly comorbid with other psychiatric disorders. Supplement usage such as performance enhancing supplements is becoming increasingly common, especially among younger populations. Using different supplements has been shown to put adolescents at an increased risk for body dysmorphia, disordered eating behaviors, as well as other potentially harmful health effects, like electrolyte complications, heart issues, or even death. Across the …

The Fitness Cost Of Rifampicin-Resistant Rpob Mutations On Mfd-Mediated Processes In Stationary Phase Bacillus Subtilis, Amber Callaway, Jessica Grifaldo

Undergraduate Research Symposium Posters

Rifampicin is a potent antibiotic that tightly binds to the ꞵ-subunit of RNA polymerase and blocks initiation of transcription. Bacillus subtilis cells that acquire rpoB mutations that confer resistance to rifampicin also exhibit decreases in transcription and fitness. Mutation frequency decline (Mfd) is a global transcription regulator that interacts with the ꞵ-subunit of RNA polymerase, and our RNA-seq showed that it had profound effects on the expression of motility genes. We hypothesize that the rifampicin-resistant rpoB: I681T mutation alters Mfd-mediated gene regulation of motility in Bacillus subtilis. Therefore, we will construct mfd- rpoB: I681T double mutants via natural competence and …

Dorsal/Ventral Orientation Of Dentate Granule Cells And Its Impact On Electrophysiology In Mice, Jacob Prince, Savannah Sampson, Alyssa Marron

Undergraduate Research Symposium Posters

The hippocampus has known roles in memory formation, learning, and spatial mapping. There are defined physiological differences between CA1 neurons based on their dorsal to ventral position within the 3D hippocampus (Malik et al., 2015). Given the varying functions of the dorsal and ventral hippocampus in cognitive processing and the role of the dentate gyrus as the entry point for information into the hippocampus, it will be interesting to determine if there are differences in the properties of granule cells across the dorsal and ventral axis. We explore the potential topographic specialization of dentate granule cells. This study examines the …
