Exploring Ai-Driven Scaffolding For Critical Questioning In Argument Evaluation, Ebenezer A. Belete

UNLV Theses, Dissertations, Professional Papers, and Capstones

The fast-paced changes caused by generative AI (GenAI) innovations call for exploring the potential benefits of GenAI in empowering 21st-century pedagogical strategies. Previous studies in the field of argumentation have shown how students can benefit from using critical questions. However, scaffolding argument evaluation through custom GenAI using critical questions has not been systematically investigated. This study involved two components: (1) designing and determining the usability of a GPT-powered conversational assistant (CQMAA Conversational Assistant) and (2) testing its impact on participants' efficacy for argument evaluation and their acceptance of GenAI as a learning tool through a pretest–posttest experiment. A convergent mixed-methods …

Perception Of Emotions In Autism With Controlled Elicitation, Rachel E. Dewald

UNLV Theses, Dissertations, Professional Papers, and Capstones

Research on emotion recognition in autism has traditionally relied on stimuli developed and validated exclusively with allistic populations. Whether these stimuli function equivalently for autistic individuals remains unclear, limiting the field’s ability to draw conclusions about cross-neurotype differences in emotional processing. Grounded in double empathy theory and cross-cultural research demonstrating in-group advantages in emotion recognition, this thesis investigated whether the Database of Emotional Videos from Ottawa (DEVO), a dynamic emotional elicitation database validated with allistic participants, elicits comparable emotional responses in autistic individuals. Participants (N = 116) viewed DEVO video clips and rated their emotional responses using the Multidimensional Visual …

Organizing The Life Story: The Structure, Retrieval, And Flexibility Of Autobiographical Memories, Erin Murphy

UNLV Theses, Dissertations, Professional Papers, and Capstones

This dissertation focused on the characteristics and flexibility of autobiographical memories within the life story, based on Conway and Pleydell-Pearce’s (2000) self-memory system and McAdams’s (2001) narrative identity theory. In two experiments, the research examined how retrieval goals and hierarchical organization influence the recall of different autobiographical memories (i.e., specific events that occur within one day, and chapters that are longer) and the flexibility of the temporal boundaries and duration of these memories. In Experiment 1, task instructions about recalling life story memories were manipulated to examine whether subtle shifts in retrieval goals influenced the type of memories recalled. Experiment …

Is Forgetting Independent Of Learning? An Examination Of Initial Learning Across Alternative Forgetting Analyses, Rhiannon Nicole Soriano Smith

UNLV Theses, Dissertations, Professional Papers, and Capstones

A long-standing debate has reappeared regarding whether the rate of forgetting is independent or dependent upon the initial degree of learning. Interestingly, both conclusions have been supported. These diverging conclusions could be due to the analytical method and operational definition of forgetting employed: Researchers supporting independence typically measure forgetting as the number of items forgotten at a given retention interval, while those in favor of dependence typically measure forgetting as the number of items forgotten between test intervals. The current study tested whether the degree of learning affects the rate of forgetting for recognition accuracy (da) and other memory processes …

Exploring Non-Native English Learners’ Attitudes Towards Ai And Online Multimedia Persuasive Opinions And The Role Of Sentiment, Zvetomira N. Svetleff

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study and various other studies use quantitative models to identify which persuasive features predict persuasiveness. Most studies in the field do not explain why participants responded as they did nor do they focus on studying adult non-native English learners also referred to as second language (L2) English learners. Despite seemingly remarkable progress on research related to how to convey persuasive messages, there has been little work related to persuasive messaging targeted at second language learners or non-native speakers. In addition, despite the increasing reliance on AI technologies and tools in language learning within educational and work settings, there has …

Face Recognition Ability: The Role Of Facial Experience Across The Lifespan, Kirsty Kulhanek

UNLV Theses, Dissertations, Professional Papers, and Capstones

The other-race effect is a phenomenon in which individuals are better able to recognize individuals of their own race than individuals of another race. These effects begin to develop during the first year of life and may be attenuated by intergroup contact. Limited research in the language domain has suggested that multilingualism may result in easier learning of non-native speech contrasts, so it is of interest whether early experience with racially diverse faces may result in more easily learning to recognize unfamiliar race faces. We conducted two studies to examine the effects of early diverse experience with faces on recognition …

Understanding The Gaming Disorder–Depression Co-Occurrence: A Narrative Literature Review, An-Pyng Sun, Stephanie Diez

Social Work Faculty Research

Because gaming disorder (GD) often co-occurs with depression, understanding how both disorders work together enables clinicians to better treat individuals with GD–depression comorbidity. The extant literature on GD–depression comorbidity is unsystematic and contradictory, with some studies suggesting depression predicts GD but not vice versa, some claiming GD predicts depression but not vice versa, and some proposing a bidirectional relationship between the two. The goal of this narrative review is to explore and organize these findings to establish a holistic and coherent conceptual framework that explains how GD co-occurs with depression.

The PubMed, PsycINFO, and Web of Sciences databases were searched …

Error Processing In Psychopathy: An Analysis Of Event Related Brain Potentials And Post-Error Task Behavior, Ananda Liz Peixoto Couto

UNLV Theses, Dissertations, Professional Papers, and Capstones

Performance monitoring and error processing are crucial for learning from mistakes, adjusting responses, and adapting to the environment. Individuals with psychopathy present with failures in performance monitoring, particularly a failure to learn from experience, and error processing deficits have been reported in this population. Error processing literature has investigated its underlying mechanisms via two prongs, namely behavioral measures and electroencephalography (EEG) indicators. Behaviorally, error processing literature has focused on post-error slowing (PES) and post-error accuracy (PEA). Meanwhile, EEG research has identified two components of error-related brain potentials (ERPs) in error processing: error-related negativity (ERN) and error positivity (Pe). This study …

Exploring The Processing Of Objects, Settings, And Global Properties In Natural Auditory Scenes, Margaret A. Mcmullin

UNLV Theses, Dissertations, Professional Papers, and Capstones

Our auditory system has a remarkable ability to make sense of complex environments, allowing us to identify what we are hearing and where sounds come from. This process of auditory scene analysis is essential for situational awareness, decision-making, and effective communication in daily life. While much is known about how listeners segregate and identify individual sound sources (e.g., voices), less is understood about how global properties of a scene (e.g., openness, naturalness) contribute to perception. This dissertation examined how object- and setting-level information in natural auditory scenes are processed, and whether they rely on distinct or overlapping mechanisms. In Experiment …

The Speech-To-Song Illusion Across Development And The Effects Of High-Level Expectations, Rodica R. Constantine

UNLV Theses, Dissertations, Professional Papers, and Capstones

The typical listener can readily categorize auditory stimuli as either speech or song even though these structures share many acoustic similarities. These musical and linguistic categories may nevertheless take time to develop as children acquire language- and music-specific knowledge. In the Speech-to-Song (STS) illusion, multiple repetitions of a natural spoken utterance can give rise to a perceptual switch wherein the stimulus begins to sound song-like to the listener. While the STS illusion has been well-researched in adult listeners, it had yet to be investigated in children. In our study, we examined whether children experience the STS illusion by presenting participants …

Stronger Together: A Mixed-Methods Examination Of Identity, Efficacy, And Emotions In Young Adults’ Collective Action, Kindy Insouvanh

UNLV Theses, Dissertations, Professional Papers, and Capstones

Young adults are increasingly engaging in collective action for social change, yet we lack a clear understanding of the factors driving their participation in social movements. This mixed-methods study uses a social psychological framework to examine key quantitative factors related to young adults’ intentions to engage in collective action for racial justice, as well as their reasoning around their involvement. A survey of 373 racially and ethnically diverse young adults (18-35 years old) assessed the impact of racial justice ally identity, emotions (anger and contempt), and dimensions of efficacy on action intentions. Path analysis revealed that young adults’ identification as …

The Role Of Prediction Error In Episodic Memory, Kevin D. Mohawk

UNLV Theses, Dissertations, Professional Papers, and Capstones

Predictions play an important role in our everyday lives. We make predictions (whether conscious or unconscious) about what we will encounter. However, we will also experience discrepancies between predictions and observed outcomes (i.e., prediction error; PE). There are inconsistencies in the literature regarding how PE affects memory. Several studies find that PE facilitates memory (e.g., Greve et al., 2019), while others find that it harms memory (Kim et al., 2013). The aim of the present study was to determine which conditions may lead to PE facilitating memory and which conditions may lead to worse memory. We tested two PE models, …

Divided Attention With Long-Term Memory: Recollection And Familiarity For Musical Melodies, Gaia Steinberg, Jackson S. Pelzner, Rhiannon N. Soriano Smith

Undergraduate Research Symposium Posters

Objective: Test whether the well-established effects of divided attention 1, 2. (DA) found with non-musical (i.e., verbal and pictorial) materials generalized to musical melodies.

Background: Few studies have used melodies to test recognition models (e.g., DPSD). Parks et al.2 showed stimulus complexity alters source memory reliance on recollection (R) and familiarity (F).

Method: Used a 2 (attention) x 2 (melody type) mixed design with an old-new recognition test to compare DA effects across well-known and novel melodies.

Experiment 1: Applied an n-back task to split participants’ attention; no significant DA effect was observed.

Experiment 2: Shortened melody length and added …

Effect Of Epistemic Cognition And Self-Regulation On The Evaluation Of Online Information, Devin T. Foschi

UNLV Theses, Dissertations, Professional Papers, and Capstones

While research has shown that epistemic cognition plays an important role in self-regulation, the way in which it does so in online contexts needs further research. The objective of this dissertation was to examine the relationship between Internet-specific epistemic cognition and Internet-specific self-regulated learning, and to use a mixed-methods approach in order to expand upon the way learners undergo the evaluation of information in online spaces beyond the traditional method of only using self-report measures and other common quantitative techniques. Using an explanatory sequential mixed-methods design, Phase 1 (N = 117) used quantitative methods to first look at the relationship …

Music And Narrative Memory, Maxwell Kayser

UNLV Theses, Dissertations, Professional Papers, and Capstones

Music can overlap with many activities, but its effects on our memory for those activities are not fully understood. The experiments here investigated the effects of calm and intense background music on both memory and narrative transportation (the feeling that one is absorbed into the events of a narrative) during reading. Participants read narratives either in silence or with background music and completed a measure of narrative transportation (Transportation Scale-Short Form; Appel et al., 2015). Participants were then tested, either in silence or with background music, on memory for explicit details and inferences from the narrative. Across both experiments, memory …

The Utilization Of String Pulling To Determine Female Rats' Dual Cognitive Motor Task Performance Following Space Flight Stressor Exposure, Doc-Haden Rodgers, Nicole M. Atttallah, Teresa L. Garcia, Nuhamine A. Moges, N. A. Moges, K. D. Omengan, J. F. Cortez, K. S. Dhede, A. A. Blackwell

Undergraduate Research Symposium Posters

During deep space exploration, astronauts depend on mission-essential performance in Dual Cognitive Motor Tasks (DCMT), such as receiving information from ground control to assemble and configure wires during a spacewalk. DCMT relies upon processing cognitive and motor information simultaneously. Previous research on rodent models has shown various impairments in cognition and motor function in separate tasks after exposure to deep space radiation and sleep fragmentation (SF). However, an assessment of DCMT performance in rodents has not been established. Rats and humans use similar hand-over-hand movements to pull a string, and task demands may be varied to assess cognition and motor …

The Characterization Of Cooperative String-Pullung Behavior In Rats After Exposure To Space Flight Stressors, Teresa L. Garcia, Nuhamine A. Moges, Sierra Ordonez, Nicole M. Attallah, D. H. Rodgers, A. Adhikari, K. D. Omengan, D. Lloyd, S. L. Gleed, A. A. Blackwell

Undergraduate Research Symposium Posters

Astronauts work cooperatively to complete tasks on missions through deep space where they will experience stressors, including radiation and sleep fragmentation, that may impair performance. Animals work together to achieve a common goal during cooperative tasks using string-pulling behaviors. While string-pulling behavior has revealed deficits in rat sensorimotor function after exposure to space flight stressors, it has yet to be determined if rats will engage in cooperative string-pulling or if these stressors will influence cooperation. Thus, to explore how space flight stressors impact cooperative behavior, female Wistar rats were exposed to either sham (n = 8) or 10 centi-grays of …

Music’S Influence On Focus And Concentration: A Puzzle-Solving Task Study, Daniyal Kheradmand, Alison Sloat

Spectra Undergraduate Research Journal

This research investigates the effect of preferred music on enhancing focus and concentration during puzzle-solving tasks. Conducted with a diverse group of 50 participants at the University of Nevada, Las Vegas, the study examined the influence of individual musical preferences on cognitive performance. Participants were tasked with solving puzzles under two conditions: listening to their favorite music and in silence. The findings reveal that 68% of the participants demonstrated improved performance in puzzle-solving when listening to music they preferred. This suggests a significant positive correlation between preferred music and enhanced cognitive task performance. The study contributes to the understanding of …

Reminders Of Reconsolidation: Prediction Error Vs. Spatial Context, Mateo Marquez, Jessica Nguyen, Augustine Alvarado

Undergraduate Research Symposium Posters

Reconsolidation is the process whereby reactivating a consolidated memory can bring it into a labile state where it can be strengthened, weakened, or updated. Spatial context and prediction error (PE) are two ways that memories can be reactivated. Spatial context refers to being in the same-environmental setting during encoding and retrieval, whereas PE refers to the mismatch between expected and observed events. Both methods have successfully reactivated consolidated memories. However, it is unclear whether reconsolidation is affected by PE when it isolated in different spaces.

The Role Of Prediction Error In Episodic Memory, Natalie Chisam, Natalie Hsiao

Undergraduate Research Symposium Posters

Prediction Error and Memory: Memory encoding and retention is influenced by prediction errors (PE), which occur when observed events deviate from expectations. Predictive Based Theories: Several theories have been proposed to predict how PE influences memory.

The Influence Of Prediction Error Strength On Reconsolidation, Kevin D. Mohawk

UNLV Theses, Dissertations, Professional Papers, and Capstones

It has been well established that consolidated memories can be reactivated and enter a labile state where they are once again vulnerable to modification. Reactivated memories, therefore, need to be restabilized or reconsolidated. Prediction error (PE) is one of the most common ways of reactivating consolidated memories, yet no studies have examined how varying the strength of PE influences reconsolidation. The present study aimed to determine if the strength of PE is an important factor for triggering reconsolidation and if so, how PE strength influences the reconsolidation process, whether through strengthening or weakening the memory. To vary PE strength, participants …

The Effect Of Sleep And Emotion On Pattern Separation, Alanna N. Osmanski

UNLV Theses, Dissertations, Professional Papers, and Capstones

Prior work on the relationship between sleep and memory suggests that the sleep state is an optimal time for memory consolidation to occur. During slow wave sleep, newly encoded information in the hippocampus is repeatedly activated, driven by slow oscillations that originate in the neocortex. This process that occurs during slow wave sleep facilitates the long-term storage of memories. A widely accepted view of emotion and sleep is that emotional memories are preferentially consolidated during sleep so that they are easily accessible for retrieval, whereas neutral memories tend to be less accessible. However, recent meta-analyses of sleep, emotion, and memory …

Comparing Comics And Illustrated Texts In Multimedia Learning, Jackson S. Pelzner

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this research was to examine how different forms of media, in particular science comics and illustrated texts, contribute to different patterns of learning. While the standard illustrated text seen in a textbook has been a useful tool for instruction, science comics appear to be an alternative that could be used in lieu of media that use the traditional illustrated text format. The comic format, known more for its visual appeal to readers, is consistent with the principles of the Cognitive Theory of Multimedia Learning (Mayer, 2009), though comprehension may require different mechanisms (Cohn, 2013a). It was hypothesized …

Testing Wickelgren's Model Of Interference And Decay, Gabriel Hull, Isabella Lacy

Undergraduate Research Symposium Posters

Two explanations have been proposed to explain forgetting: decay (forgetting occurs as a function of time) and interference (the mental activity can impinge on the consolidation of a recently acquired memory). Wickelgren (1974) proposed a model of forgetting which suggests that forgetting is a function of both decay and interference, best expressed as a power-exponential function. The present research will be the first to directly examine whether Wickelgren’s model accurately predicts the observed effects of these two components on forgetting. This research will further the study of human memory by improving current models, and helping to resolve the debate surrounding …

Malice Within Meanness In Psychopathy Predicts Unrestricted Sociosexuality, Michal Newhouse-Van Vlerin

Undergraduate Research Symposium Posters

This study examines the relationship between the Meanness in Psychopathy-Self Report Short Form (MiP-SR-SF) and the Sociosexuality Orientation Inventory-Revised (SOI-R). It links the fields of personality and sexual functioning.

Self-Blame Associated With Sexual Maltreatment, Jessica Castillo, Mallory Constantine

Undergraduate Research Symposium Posters

Sexually maltreated youth are at increased risk for developing thoughts of self-blame associated with their traumatic experiences (Melville et al., 2014). Self-blame increases risk of maladaptive emotion regulation strategies and self-harming behaviors (Gorgi et al., 2019). Self-blame can cause negative side effects in development and adulthood, changing the trajectory of the child who was affected by sexual assault (Ullman et al., 2014). Recent studies suggest we must continue to investigate the role in shame in producing meaning making progress, and how it affects other emotions, cognitive learning, and emotion regulating strategies (McElvaney et al., 2022). In order to continue to …

You're So Harsh On Me: Meanness In Psychopathy And Perceived Family Criticism, Jordan E. Hayes, Kayla Mcginty

Undergraduate Research Symposium Posters

Overall, the lack of research on percieved criticism, especially within populations that display meanness, show a need for research because just like mood, percieved criticism may change throughout the day. Understanding the relationship between psychopathic meanness and momentary patterns of percieved criticism among family members could provide helpful insight into social interactions and elucidating patterns of family dysfunction involved in the most antagonistic features of psychopathy.

The Stability Of The Speech-To-Song Illusion And Individual Differences, Rodica R. Constantine

UNLV Theses, Dissertations, Professional Papers, and Capstones

Music and language are easily distinguishable for the average listener despite sharing many structural acoustic similarities. The Speech-to-Song illusion can give rise to both musical and linguistic percepts by inducing a perceptual switch after listening to multiple repetitions of a natural spoken utterance. As such, it has been used as a tool to control for low-level acoustic characteristics previously shown to drive lateralized brain responses regardless of domain-type, helping to disambiguate the contribution of high- versus low-level processes in both music and speech perception. However, there exists a lack of research on how large a role individual differences such as …

Dimensionality Of Natural Auditory Scene Perception: A Factor Analysis Study, Margaret A. Mcmullin

UNLV Theses, Dissertations, Professional Papers, and Capstones

Theories of auditory and visual scene analysis suggest the perception of scenes relies on the identification and segregation of objects within it, resembling a detail-oriented processing style, but it is possible that a global-oriented process also occurs while evaluating auditory scenes. There is evidence for global properties that enable rapid recognition of visual scenes, even without recognizing the individual objects comprising the scene. It is our understanding that a similar line of research has not been explored in the auditory domain; therefore, we evaluated the contributions of high-level global and low-level acoustic information to auditory scene perception. A secondary aim …

Comparing Forgetting Rates Between Pattern Separation And Item Recognition, Rhiannon N. Soriano Smith

UNLV Theses, Dissertations, Professional Papers, and Capstones

Recent theories of forgetting posit that hippocampally-based memory representations are more prone to be forgotten due to decay, while extra-hippocampal representations are more likely to be forgotten due to interference (Hardt, Nader, & Nadel, 2013; Sadeh & Pertzov, 2020). The current study examined this hypothesis by comparing the rate of forgetting between pattern separation, a hippocampally-based process, and item recognition, a process that is reliant on both hippocampal and extra-hippocampal structures. It was hypothesized that pattern separation would display more forgetting due to decay because it is a hippocampally-based process, while item recognition would display more forgetting due to interference …
