Collaborative Memory And Metamemory: The Impact Of Normative And Informational Motivations On Conformity, Karen Rodriguez

Dissertations, Theses, and Capstone Projects

Collaborative memory studies have typically explored the cognitive mechanisms that underlie differences between collaborative and individual memory performance. Despite the social nature of collaboration, few studies have examined the impact of social motivations on collaborative memory. When retrieving information with groups, people may not only be motivated by a desire to be accurate (i.e., informational motivations), but may also be guided by social norms (i.e., normative motivations), such as prioritizing agreeability or alignment with group members (Cialdini & Goldstein, 2004). Similarly, retrieving information with others may also prompt individuals to reflect more on their own memory processes. However, few studies …

Using Machine Learning Methods To Evaluate Undergraduates’ Executive Function In The Context Of Game-Based Measurement, Ming Chen

Dissertations, Theses, and Capstone Projects

Traditional performance-based measurements have faced criticism due to their potential to induce test fatigue and their limited ecological validity. In contrast, game-based assessments have demonstrated the capacity to engage participants effectively in tests and enhance ecological validity by replicating real-world scenarios. Nevertheless, conventional statistical approaches may prove insufficient in capturing the intricate, non-linear associations between participants' gaming performance and their cognitive capabilities. Leveraging the potential of machine learning (ML) techniques, which can model complex problems, offers a promising avenue for estimating students' performance in video games. This dissertation aims to explore various ML methods for the validation of three game-based …

Characterization Of The Attentional Profile In Women And Girls With A Fragile X Premutation Allele, Shira Russell-Giller

Dissertations, Theses, and Capstone Projects

The fragile X premutation (PM), characterized by 55 to 200 CGG repeats in the FMR1 gene, is associated with diverse clinical outcomes, including cognitive and neuropsychiatric changes. Despite most individuals with a PM presenting without overt clinical symptoms, adults face increased risks for conditions associated with a PM, including higher rates of attention and executive difficulties. This dissertation investigates the developmental trajectory of attention and executive functioning changes in females with a PM using a series of prospective studies employing the Attention Network Test (ANT). Study 1 re-analyzed prior data on sustained attention in women with a PM, revealing significant …

The Interaction Of Multilingualism And Depressed Mood On Cognitive Set-Shifting, Annalise Caviasco

Dissertations, Theses, and Capstone Projects

Although findings are mixed, many researchers believe there are cognitive benefits to multilingualism, a phenomenon dubbed the “bilingual advantage”. Of these apparent benefits, cognitive flexibility, or the ability to shift thinking styles based on the context or specific demands of a certain situation, is thought to be highly relevant. Current literature suggests that one aspect of multilingualism, the practice of “code-switching” between languages throughout their daily lives, is related to increased general cognitive flexibility compared to monolinguals. Another branch of research on cognitive flexibility investigating the role of affect in cognition demonstrates that clinical depression as well as transient negative …

Unveiling The Precision Of Physiological Signals In Prediction Error During Fear Learning: Insights From Associative Strength And Generalized Uncertainty, Haja H. Jallo-Jamboria

Dissertations, Theses, and Capstone Projects

Prediction error (PE) is the discrepancy between expected and actual outcomes. It is a central mechanism in associative learning particularly within fear-conditioning paradigms. Identifying physiological markers of PE in aversive contexts has important implications for refining learning models and enhancing clinical interventions for anxiety-related disorders. This study examined skin conductance response (SCR) as a potential physiological index of PE by analyzing both anticipatory and omission-related responses across multiple learning phases. Participants completed a Pavlovian fear-conditioning paradigm in which two conditioned stimuli (CS+) signaled threat at different reinforcement probabilities: CS+100 (certain threat) and CS+50 (uncertain threat), alongside a non-reinforced safety cue …

Wavelength And Luminance Interaction On Spatio-Temporal Contrast Sensitivity Function, Taylan S. Ergun

Dissertations, Theses, and Capstone Projects

Contrast sensitivity (CS) measures the ability to discriminate objects from their backgrounds under varying conditions(Campbell & Robson, 1968). Contrast sensitivity is important for navigating the real world and operating under different light conditions. The contrast sensitivity function (CSF) reflects how the visual system performs under different conditions. This measure is crucial in assessing the health of the visual system (Chen & Gardner, 2021). CSF contributes to a deeper understanding of how the visual system processes and integrates properties of light to create visual sensation and perception. Human contrast sensitivity depends on the viewing conditions such as field size, luminance, color, …

Conscious Control: A Case Study On Self-Monitoring And Interventions In Maladaptive Daydreaming, Caleb Chan

McNair Research Journal SJSU

Maladaptive daydreaming (MD) is a persistent mental activity

characterized by immersive, excessive daydreaming that disrupts daily

life. This study examines the effectiveness of self-regulation strategies

in managing MD, including cognitive techniques, behavioral

adjustments, technology-assisted cues, and environmental

modifications. Using a single-subject ABA design, each intervention

phase lasted one week, with MD episodes tracked through self-reported

diaries and EEG monitoring. The results demonstrated that cognitive

reframing and task switching produced the most sustained reductions in

MD episodes, while technology-assisted cues had diminishing

effectiveness over time due to adaptation. Environmental modifications,

particularly workspace reorganization, con- tributed to long-term

improvements, while lighting adjustments …

Proposed Theoretical Model Of Pediatric Onset Multiple Sclerosis And Restrictive Eating Behaviors, Anna L. Smith

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Multiple Sclerosis (MS), a chronic, demyelinating, autoimmune disease that causes an array of physical and cognitive symptomatology, is commonly diagnosed in adulthood. Pediatric Onset Multiple Sclerosis (POMS) is characterized by diagnosis of the disease before age 18 and accounts for about 5% of MS cases. While there is a growing body of literature examining the impact of adult-onset multiple sclerosis on psychosocial functioning, research specifically addressing POMS remains limited. Moreover, there is a notable gap in the literature regarding the risk of eating disorders among individuals with POMS. This paper will explore a constellation of potential risk factors that may …

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 …

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 …

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 …

How Cultural Intelligence Shapes Communication And Decision-Making In Multicultural Teams, Jonathan Freking

The Scholarship Without Borders Journal

This study explores how cultural intelligence influences patterns of communication and decision-making in multicultural teams, with particular attention to behaviors such as turn-taking, conflict resolution, and feedback. Drawing on a thematic analysis of 45 peer-reviewed articles spanning foundational theories, empirical studies, and methodological approaches, this paper identifies six key themes: the evolution of the CQ construct; CQ as an adaptive communication mechanism; its role in conflict resolution; its influence on collaborative decision-making; the emergence of collective cultural intelligence; and methodological approaches for understanding CQ in context. Findings suggest that high-CQ individuals and teams demonstrate more equitable voice distribution, engage in …

The Use Of Sludge Content For Effective Recall Of Information, Rahaf G. Fares

Electronic Theses, Projects, and Dissertations

In an age where social media dominates daily consumption, the impact of engaging multi-modal media, specifically “sludge content,” on attention and memory has garnered significant interest. Sludge content, which generally combines unrelated visual gameplay with narrated audio and subtitles, has emerged as a popular form of online entertainment. This study explored whether this type of content enhances information recall by capturing users’ attention, a claim bolstered by theories of optimal arousal, non-pharmacological interventions such as fidget toys, and audiovisual redundancy. Using a within-subjects experimental design, the study investigated the effects of sludge content on effective recall through three conditions: sludge …

Decision Field Theory For Human-Multi-Robot Collaboration: Human-Centric Decision-Making For Multi-Robot Systems, Ryan Mbagna Nanko

All Theses

At first glance, choosing between an apple and an orange appears to be a straightforward matter of personal taste; however, this seemingly simple preference opens a window into the multifaceted world of decision-making, revealing the complex interplay of cognitive processes, psychological, and behavioral-economic principles that guide our choices \cite{bandyopadhyayRoleAffectDecision2013}. By unpacking these nuanced perspectives, we uncover insights that can drive more effective human-robot interaction and collaboration.

Modeling human cognition requires understanding the evolution of choice utility and the influence of emotions. Decision Field Theory (DFT) stands out by capturing the fluctuating nature in human preferences over time, explaining why choices …

Longitudinal And Bidirectional Relations Between Problematic Social Media Use And Cognitive Failures, K. T. A. Sandeeshwara Kasturiratna, Andree Hartanto

Research Collection School of Social Sciences

With social media becoming increasingly pervasive in our daily lives, there have been heightened concerns that the distractions caused by compulsive and problematic social media use may lead to cognitive failures. While some preliminary work have explored the link between problematic social media use and cognitive functioning, most are cross-sectional, leaving it uncertain whether cognitive failures are a precursor or consequence of problematic social media use. To address this gap, the current study examines the bidirectional relationship between problematic social media use and cognitive failures. A sample of 252 young adults completed the Problematic Social Media Use Scale and the …

One Step Closer To Greater Understanding! Does A Correlation Exist Between Fluid Intelligence And Player Rank In League Of Legends?, Evan Miller

Dissertations

Chess, one of the oldest modern games, has long been a model domain for expertise research. In comparison, research on video games has historically been influenced by moral panic. Cycles of moral panic tend to revolve around preconceived notions of threats, held at a societal level (typically by older generations). Politicians, quick to capitalize, then advocate for policy change based upon their constituents’ fears. Concurrent media reports draw further attention to the issue, amplifying the perception of harm. As the panic escalates, pressure is placed on scientific communities to perform confirmatory (not exploratory) research. This fundamentally biased approach to research …

Flex-Spatialities: Interior Spaces, Play, And Fantasy, Camilo Lozano-Rivera

Interiority

This article examines how interior spaces in the digital age have evolved into flexible, adaptive environments shaped by technological mediation and shifting everyday practices. Focusing on smart homes and home offices, this article introduces the concept of flex-spatiality to describe how these spaces continually reconfigure in response to changes in needs and digital interfaces. Grounded in Gregory Bateson’s (1972) theory of play and fantasy, the study explores how interior spatiality operates on two levels: as a locus for expressing identities and as a structure for organising social interaction. Through Bateson’s distinction between metalinguistic and metacommunicative functions, flex-spatiality is framed as …

Computational Thinking As A Novel Framework For Enhancing Cognitive Organization In Older Adults With Cognitive Frailty (Letter To The Editor), Daisuke Akiba

Publications and Research

As aging populations grow, especially in high-income nations, the burden of dementia-related care continues to escalate both economically and socially. In response, this article introduces Computational Thinking (CT) as a novel, non-pharmacological framework to support cognitive organization in older adults experiencing cognitive frailty. Though CT has gained traction in fields like PK-16 education, including special education, for enhancing executive function and problem-solving, it has not yet been applied to geriatric- or memory-care contexts. This perspective proposes that CT’s core components (i.e., decomposition, pattern recognition, abstraction, and algorithmic thinking) may align with residual cognitive strengths in mild-to-moderate dementia, offering a strengths-based, …
