How Human Personality Will Change With The Use Of Artificial Intelligence, John Mayer

UNH Personality Lab

INTRODUCTION: Human personality changes in response to new habits, situations, and maturation, among other causes. As people interact with artificial intelligence (AI), their personalities are likely to change, from their emotional responses to their self-concept.

METHODOLOGY: This theoretical account draws together empirical studies of how personality changed in response to past technological innovations, changes in personal interactions observed in people’s AI usage, changes that arise from the use and disuse of cognitive skills, and works on the self-concept. Research reports in the review were selected according to their relevance and quality.

THEORETICAL STATEMENT: While AI becomes increasingly human-like, humans increasingly …

Digital Neuropsychology And Social Anxiety: The Effect Of Observer Presence And Personality On Stress And Cognition, Ava M. Dixon

Master's Theses

This study examined how observer presence and social anxiety influence stress and cognitive performance during neuropsychological assessments, focusing on the potential benefits of unsupervised digital testing environments. Eighty university students were randomly assigned to observed or unobserved digital neuropsychological conditions and completed assessments of social cognition and executive functioning and questionnaires of social anxiety and personality. Participants also completed measures of state anxiety and heart rate variability at baseline and after cognitive tests. The findings indicated that observation led to higher subjective anxiety, but it did not produce significant interactions with social anxiety on stress or cognitive performance. Post-hoc analyses …

An Updated Perspective On Learning, Andrew S. Gibbons Iii

Faculty Publications

The subject of human learning is revisited. The emergence of new research findings in cognitive neuroscience and related disciplines using new imaging tools and techniques has revealed the existence of not one but two complementary learning systems. A newly-discovered prospection process, interacting with both memory systems, has been revealed as the pivotal mechanism of learning that leads to new experience and new memory records. The universal impact of emotion on this process also receives a new emphasis. This, coupled with the ever-present social environment, show learning to be the result of conversational activity. The existence of this more complete and …

The Impact Of Adverse And Positive Childhood Experiences And Moral Injury On Compassion Fatigue Among Law-Enforcement Officers And First-Responders, Kaylee Nesland

Doctor of Psychology (PsyD)

More than ever, United States law enforcement officers are overworked, under-trained, and exposed to a great deal of trauma. Societal pressure to display strength and resilience, as well as fears of judgement and loss of job security, inhibit law enforcement officers from accessing psychological treatment and support (Drew & Martin, 2021). Without mental health support in place, compassion fatigue reveals itself, ultimately causing hurt and damage to individuals in law enforcement and those they interact with. This study examined whether adverse or positive childhood experiences affect compassion fatigue among law enforcement officers. Participants of this study—current and historical law enforcement …

Divorcees’ Experiences Of Hubristic Pride In Communication In Previous Marital Relationships, Amanda Harms

Walden Dissertations and Doctoral Studies

Poor communication practices have significantly strained marital relationships, contributing to increased divorce rates in the United States. As a self-conscious emotion, hubristic pride often leads to poor communication, which in turn exacerbates marital discord and contributes to the breakdown of families. The purpose of this basic qualitative study was to explore how divorcees perceive the impact of hubristic pride on communication in their previous marriages. The theoretical framework underpinning this study was Homans’s social exchange theory. Data were obtained from eight divorced participants not actively involved in ongoing custody proceedings through semistructured interviews and analyzed using Saldaña’s descriptive coding methodology. …

Dating In The Digital Age: The Effects Of Parental Rejection, Rejection Sensitivity, And Self-Esteem Among Gender-Diverse Gen Z, Crystal Currie

Walden Dissertations and Doctoral Studies

Gen Z, the first digital-native cohort, faces unique challenges in forming romantic relationships, including heightened dating anxiety. While there is extensive research with previous generations on dating anxiety, self-esteem, and early rejection, no study has examined parental rejection, self-esteem, and dating anxiety collectively, particularly in consideration of gender diverse individuals and digital dating platform use. The purpose of this correlational study was to examine (a) predictors of dating anxiety and (b) whether parental rejection during childhood and rejection sensitivity influenced dating anxiety, as well as the role of self-esteem in mediating those predictor variables. The conceptual framework was the interpersonal …

Visual Attention, Emotional Arousal, And Moral Judgment In Legal Evidence Processing, Audrey G. Laskey, Kyra Cannon, Josette Sanders, Lingfei Luan

Science University Research Symposium (SURS)

Moral judgment in legal decision-making is influenced not only by the evidence presented but also by emotional and attentional processes. Prior research has shown that physiological arousal during exposure to emotionally charged or socially relevant information can shift the way evidence is evaluated and weighted in decision-making (Armstrong & Olatunji, 2012; Godwin et al., 2016). However, few studies have examined how autonomic arousal relates to guilt decisions using real, high profile case materials. We were interested in examining how possible exposure to violent content on social media might desensitize individuals, like jurors, leading to lighter judgments for serious crimes. This …

Empathy On Trial: The Role Of Neuroscience And Communication In Sexual Violence Jurisprudence, Samantha M. Gonzales

Honors Program Theses and Research Projects

Sexual violence remains a contentious public safety and legal challenge, which has become further complicated by the tension between supporting victim-survivors and safeguarding the falsely accused. False accusations, though still well below the numbers of rightly accused, are experiencing a rise in popularity given recent (past ten years) political climates. This thesis examines how communication theory, neuroscience, and law intersect in molding perceptions of truth, culpability, and justice in sexual violence cases; while also examining the intersectionality of those fields in addressing the candor of allegations, the rate of recidivism, and quality of public health and safety. The most prominent …

Physiological Response To Concealed Information In A Mock-Crime Paradigm​, Ezra Koenigsberg, Tamya Mchenry, Jasmine Manzana, Taylor Powell, Samantha Jackson

Science University Research Symposium (SURS)

The Concealed Information Test (CIT), based on Lykken’s guilty knowledge framework, measures physiological responses when individuals recognize crime-related details compared to neutral alternatives. Previous studies show that variations in stimulus presentation enhance the CIT’s accuracy, especially through changes in electrodermal activity and heart rate. However, few studies have tested whether a Qualtrics-based mock-crime version of the CIT can replicate these physiological patterns. This study addresses that gap by adapting the CIT for a digital research environment. The goal is to determine whether participants show greater physiological arousal—measured through skin conductance, heart rate, and respiration—when exposed to crime-related “critical” stimuli compared …

Exploring The Recognition Of Internalizing Problems Among Black Students: Delving Into The Youth Mental Health Help-Seeking Pathway, Marketta A. Adams

LSU Master's Theses

The mental health of Black adolescents is a growing concern, with high prevalence rates of internalizing disorders such as anxiety and depression. National studies report that nearly 47% of Black adolescents experience a mental health disorder by age 18, with over 60% reporting moderate to severe depressive symptomology. Despite these alarming rates, Black youth underutilize mental health services, often due to cultural stigma, limited access to culturally competent care, and under-recognition of their mental health needs. This study aimed to explore problem recognition as a key component in the mental health help-seeking pathway for Black adolescents in school settings. Grounded …

“What Are We And What’S Coming Next?”: Queer People’S Experiences During Sociopolitical Unrest In The Us, Ariana Cristal Morales

Master's Theses

Queer (lesbian, gay, bisexual, transgender, queer, or other gender and sexual identities) folx have become a major focal point during political elections. As political climates have projected forced attacks towards queer populations, society has followed suit. Investigation on the impacts of such changes towards queer folx is important to uncover, as sociopolitical climates have shifted within the last 10 years in the US. The present study utilizes a phenomenological framework to understand the lived experiences of queer participants living in the US from 2015-2025 during political and social shifts. Semi-structured interviews were utilized to explore 10 queer participant’s lived experience …

A Heart So White: Musical Reflections On Lady Macbeth's Mind, Caitlyn N. Long

Undergraduate Theses

A Heart So White: Musical Reflections on Lady Macbeth’s Mind reimagines one of Shakespeare’s most infamous characters through a trauma-informed lens. This thesis combines artistic creation with interdisciplinary research in psychology, dramaturgy, and musical theatre studies to explore Lady Macbeth’s psychological unraveling and reclaim her from centuries of villainization. Composing from Lady Macbeth’s perspective allowed for a deeper exploration of her guilt, dissociation, repression, and isolation—symptoms traditionally overlooked in favor of Macbeth’s more visible descent into violence. Through musical motifs, lyrical reinterpretation, and staging concepts, the work seeks to humanize Lady Macbeth and highlight how trauma shapes behavior, relationships, and …

Renewal Of The Mind: Forgiveness Through The Lens Of Christian Faith And Neuroscience, Khelen Walsh

University Honors Theses

Within Christian theology, forgiveness is a foundational concept that is often understood as a divine command, a spiritual practice, and a path toward reconciliation and personal growth. Recent neuroscientific research further supports this viewpoint, providing data that shows forgiveness engages neural systems responsible for emotional regulation, empathy, moral reasoning, and perspective-taking. Through neuroplasticity, repeated acts of forgiveness reshape the brain, strengthen connections between prefrontal and limbic regions, reduce amygdala reactivity, and enhance emotional stability and cognitive flexibility. Although forgiveness offers many benefits, modern culture frequently distorts its meaning, framing it as a sign of weakness, gullibility, or a form of …

Interrelationships Among Social Media Use, University Social Capital, And Mental Health Outcomes In Undergraduate Students, Md Hasan Howlader

Lingnan Theses (MPhil & PhD)

Mental health concerns among university students have intensified globally, reflected in rising levels of psychological distress, declining life satisfaction, and reduced flourishing. These challenges present urgent implications for public health and higher education policy. Simultaneously, social media use (SMU) has become deeply embedded in students’ daily lives; however, its impact on mental health remains inconclusive. While some studies associate SMU with increased mental health issues, others emphasize its potential to foster social connection. These conflicting perspectives are further complicated by uncertainty regarding the directionality of these relationships—whether SMU influences mental health, or mental health status shapes SMU patterns. Furthermore, existing …

Leadership and Strategy Faculty Publications

Understanding generational differences in engagement with Management Trainee (MT) programs is crucial for talent development, yet comparative studies linking these experiences to employee retention are limited. This study addressed this gap by investigating the distinct motivations and retention drivers of Filipino Gen Z and Millennial graduates from the MT program. Using a qualitative research design, in-depth interviews were conducted with six professionals (three Gen Z and three Millennials) who completed structured MT programs in Philippine-based organizations. The data were analyzed using a comparative thematic analysis framework adapted from Braun and Clark. Findings revealed key distinctions in motivations and retention drivers. …

Martial Arts Studies: A Commentary On The Exploration Of Consciousness In Modern Martial Arts, James H. Sutton

Journal of Conscious Evolution

The rapid globalization of martial arts has reconditioned how the beliefs, customs, and philosophies of traditionally based systems are interpreted and applied in modern practice. As contemporary scholarship struggles to accommodate the cultural histories, myths, and traditions that permeate the perception of martial arts in modern contexts, the focus of inquiry has shifted towards explaining cultural variations in practice rather than understanding the nature of self-awareness derived from self-practice. Consequently, the deeper meanings of martial arts as pathways to personal and transpersonal awareness are often invalidated in favor of objective and verifiable explications. In short, the role of consciousness is …

Exploring The Stability Of Misophonia And Other Auditory Affective Experiences Throughout Development, Erika Foregard, Rose De Kock, David Vollweiler

Undergraduate Research Symposium Posters

Sounds can give rise to powerful affective experiences, both positive and negative. Misophonia is an intensely negative response to sounds such as chewing, whereas autonomous sensory meridian response (ASMR) and musical chills result are experiences as positive and pleasant. Anecdotally, all of these experiences occur as early as childhood, but we know relatively little about how they develop. We investigated this question longitudinally.

Gendered Patterns Of Trauma & Ptsd Symptoms Among Latine Americans: A Mixed-Methods Analysis, Abigail Panariso, Gerardo Garcia, Melanie Garcia, Yajairy Carbrales, Mariam Sultan

Undergraduate Research Symposium Posters

Latine communities in the U.S. experience disproportionate exposure to traumatic events, contributing to behavioral health disparities such as elevated rates of posttraumatic stress disorder (PTSD) and underutilization of mental health care. Gender, as a key social determinant of health, influences both types of trauma encountered and the severity of symptoms. Little research has tackled how gender intersects with structural inequities within Latine populations, such as discrimination, immigration stress, and socioeconomic marginalization. This mixed-methods study assessed gender differences in trauma experiences and PTSD symptoms among 328 Latine American adults (148 men, 180 women) recruited through an online survey. We predicted gender …

Structural Equation Modeling Of Educational Factors Associated With Racial Trauma: Belonging, Efficacy, And Persistence Among Bipoc College Students, Miguel Castano, Richard Chang

Undergraduate Research Symposium Posters

Racial trauma refers to post-traumatic stress disorder symptoms from repeated exposure to racism and racial discrimination, generally expressed as hypervigilance and lack of safety, negative cognitions causing bleak perceptions of oneself and the world, and difficulty coping through reduced ability to manage distress. Literature shows that BIPOC students encounter racism on university campuses more frequently than non-BIPOC students, suggesting they are more vulnerable to racial trauma. Racial trauma has been linked to negative mental health outcomes; however, little is known about its impact on educational outcomes. Academic belonging, self-efficacy, and persistence are key educational factors tied to academic performance and …

School Shooting Drills Across Grade Levels: What We Know And Don't Know About Student And Teacher Experiences, Katherine Cutié

Undergraduate Research Symposium Posters

School shooting drills have become a standard component of school safety procedures in U.S. K–12 education, yet their psychological effects remain under-researched. This literature review synthesizes findings from 39 studies published between 1999 and 2025 to describe patterns in how students and teachers experience these drills across grade levels and drill types. Across the literature, anxiety and fear were the most frequently examined student outcomes, while teachers commonly reported stress, concerns about developmental appropriateness, and increased emotional labor during drills. Lockdown procedures were most frequently examined in the reviewed studies, with less research addressing ALICE, Run–Hide–Fight, and simulation drills. Few …

Effects Of Mental Health Clinician Characteristics And Education On Willingness To Treat Child Problematic Sexual Behavior, Debra Elise Hutchison

Walden Dissertations and Doctoral Studies

Children aged 12 and under who exhibit problematic sexual behavior (PSB) often face barriers to care due to clinicians’ limited willingness and effectiveness in treating this population. However, little is known about the factors that influence clinicians’ willingness to provide treatment. Grounded in Bowen’s family systems theory and Bandura’s self-efficacy theory, this study examined how differentiation of self (DoS), sexual intervention self-efficacy (SISE), sexual comfort, and sexual education/training affect clinicians’ willingness to treat child PSB. A quantitative, non-experimental survey design with a convenience sample of 63 clinicians with experience working with children used a multiple linear regression analysis that revealed …

Differential Substance Use Screening Approaches Among Medical Providers Based On Pregnancy Status, Ericka L. Suarez-Vella

Walden Dissertations and Doctoral Studies

Exploring medical providers’ role in relation to pregnant individuals who use substances is critical. Understanding how screening practices and provider biases influence addiction treatment referrals based on pregnancy status can help address several key issues, including potential disparities resulting from provider bias. It can ensure fair referral practices, promote equitable access to treatment, and ensure timely intervention resulting in better health outcomes. It can influence changes to policy and procedure among healthcare and judicial establishments, ultimately improving the relationship between providers and patients. The purpose of this study was to explore how medical providers’ screening practices of substance use in …

The Experience Of Black Mothers Preparing Their Black Sons For Race-Related Risks, Yamilka Torres

Walden Dissertations and Doctoral Studies

Despite progress in addressing racism in the United States, its effects remain deeply entrenched, particularly for Black families. Research on Black parenting shows that parents adapt their strategies to protect children from criminalization, discussing violence, providing safety within the home, and limiting exposure to unsafe environments while also managing their own stress. Yet limited attention has been given to how Black mothers prepare their sons for race-related risks within the modern sociopolitical climate shaped by the #BlackLivesMatter movement. The purpose of this basic qualitative research study was to explore how Black mothers prepare their Black sons for race-related risks. Carter’s …

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 …

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 …

Relationship Between Caffeine Use And Eating Disorders, Hannah Segura, Maegan Nation

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 …
