Cognitive Flexibility In Broader Autism Phenotype: Does Bilingualism Benefit And Emotion Hinder?, Nardin M. Yacoub

Theses, Dissertations and Culminating Projects

The broader autism phenotype (BAP) is a milder manifestation of autistic traits just below the clinical threshold for Autism Spectrum Disorder (ASD), and provides a framework for studying and defining these traits in individuals related to autistic people. Cognitive flexibility (CF) is an executive functioning (EF) skill characterized by the ability to switch between tasks or thoughts based on environmental demands. The current study examined whether BAP was associated with CF and how bilingualism and emotion influenced this relationship across development. Previous research has found that bilinguals show enhanced task-switching abilities. Individuals with BAP may show differences in emotional processing, …

Counselors’ Training Needs In Effectively Engaging With Psychedelic-Assisted Therapy, Elif Bor

Counseling & Human Services Theses & Dissertations

As public and scientific interest in psychedelic-assisted therapy (PAT) continues to grow, counselors are increasingly encountering clients who are exploring or engaging in psychedelic use for therapeutic purposes. Such encounters introduce new ethical, clinical, and professional considerations. Counselors must develop an informed understanding of psychedelics and their effects, recognize the emotional and cognitive processes that may emerge during psychedelic experiences, and be prepared to respond to potential risks or adverse reactions (Aicher et al., 2025). They also need to competently answer client questions, assess risk and suitability, facilitate the integration of psychedelic experiences, and collaborate with medical and other professionals …

Seeing The Unspoken: A Pilot Eye-Tracking Study Of Moral Injury Among Veterans, Eva M. Valdez

Dissertations

This pilot study examined associations between self-reported moral distress, state distress, combat exposure, deployment history, and maximum pupil reactivity among veterans diagnosed with PTSD. Participants viewed neutral and morally relevant images while pupil responses were recorded using eye-tracking technology. Self-report measures included moral distress severity, exposure to potentially morally injurious events, Subjective Units of Distress Scale (SUDS) ratings, total deployments, number of combat deployments, and Combat Exposure Scale scores. Maximum pupil reactivity was calculated by subtracting the mean z-scored maximum pupil response during neutral image presentations from the mean z-scored maximum pupil response during morally relevant image presentations. This variable …

An Evaluation Of Staff Training To Teach Implementation Of Functional Analysis Of Inappropriate Mealtime Behavior, Lauren Marie Lightner

Theses and Dissertations

Avoidant/Restrictive Food Intake Disorder (ARFID) along with other feeding disorders are prevalent in both neurotypical children along with children diagnosed with autism spectrum disorder (ASD) and other developmental disabilities. Children with feeding challenges often exhibit inappropriate mealtime behavior (IMB) to avoid consuming non-preferred foods. It is pertinent to determine the function of IMB in order to create an efficacious treatment; one such assessment is the functional analysis (Iwata et al. 1982/1994). Iwata et al. (2000) taught students how to implement a functional analysis of self-injurious behavior using behavioral skills training. Since the assessment’s development, it has been extended to various …

The Joint Effect Of Bilingualism And Sleep On Executive Functions Among Children And Adolescents With Attention Deficit/Hyperactivity Disorder (Adhd), Yirou Jiang

Doctoral Dissertations

Attention Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder that significantly impacts cognitive and behavioral functions, leading challenges for individuals across the lifespan. While extensive research has been conducted to understand the connection between executive functioning (EF) and ADHD, research findings related to the contributing factors of bilingualism and sleep still remains inconsistent (Bialystok et al., 2017). Investigating the joint effect between bilingualism and sleep on EF among children and adolescents with ADHD may help further clarify the connection between EF, language, and sleep, and facilitate the development of interventions from the perspective of these protective factors. EF encompasses cognitive processes …

Using Photovoice And Life Course Theory To Understand The Lived Experiences Of Filipino Teenage Parents, Nina Linly D. Capulong, Liane Peña Alampay, Bernice Landoy Mamauag, Jennel Drezza Fe C. Reyes

Psychology Department Faculty Publications

Teenage parents face the unique challenge of simultaneously navigating adolescence and parenthood. Rising adolescent pregnancy rates in the Philippines necessitate urgent efforts to better understand and support them. Using Photovoice, Filipino teenage parents captured their lived experiences through photographs, resulting in eight themes: (1) Managing stresses and conflicts in partner relationships, (2) Peers as a source of emotional support, (3) Support and strain in family relationships, (4) Shifts in normative adolescent experiences and priorities, (5) Strain and agency in balancing roles, (6) Desire to enhance parenting knowledge and skills, (7) Environmental drivers of early sexual exposure, (8) Sexual knowledge from …

When The Best-Fit Model Is Not Best: The Glass Slipper Fallacy And Latent Growth Mixture Modelling, Jonathan L. Chia, Markus Wettstein, Andree Hartanto

Research Collection School of Social Sciences

Despite the use of latent growth mixture modelling (LGMM) to study longitudinal changes, existing practices may inadvertently impede this very investigation. Although subgroup trajectories may theoretically differ in their structure (e.g., some subgroups being linear, some curvilinear), the current convention advocates overreliance on the baseline model to derive subsequent profile trajectories, which may obscure these structural differences. In this article, we provide a brief description of extant LGMM practices, after which we explicate the pitfalls of the current approach. Finally, we provide a principled approach for LGMM research moving forward. Specifically, we recommend specifying a set of theoretically plausible models …

Artificial Intelligence (Ai) In Forensic Psychology: An Umbrella Review Of Potentials And Pitfalls, Ysabel Thereze Ang Guevarra, Nur Eva Alisha Binte Mohamed Hisham, Andree Hartanto

Research Collection School of Social Sciences

Artificial intelligence (AI) is becoming increasingly embedded within forensic psychological practice, shaping how criminal risk, legal responsibility and public safety are assessed. AI tools are now used in recidivism prediction, behavioural analysis, deception detection and investigative support, high-stakes domains where errors can have profound consequences. Despite this rapid adoption, the existing literature remains fragmented, with most reviews confined to narrow subdomains and offering limited integrated synthesis of AI′s broader role in forensic psychology. Thus, this umbrella review addresses this gap by synthesising findings from 43 reviews obtained from five major databases, namely EBSCOhost ERIC, EBSCOhost PsycInfo, PubMed, Scopus and Web …

Caring With Ai: The Efficacy Of A Customised Chatgpt-Delivered Self-Compassion Intervention On College Students' Well-Being And Academic Functioning, Tracy Xi Chen, Chi-Ying Cheng, Andree Hartanto

Research Collection School of Social Sciences

College students face various challenges, including academic pressure, social stress, and the transition into adulthood, which can lead to increased anxiety and other mental health issues. By recognizing personal struggles as part of a shared human experience and responding with kindness, self-compassion serves as a powerful strategy for enhancing resilience, facilitating better well-being and performance outcomes. Although effective, Compassion-Focused Therapy often requires substantial resources and time, limiting its applicability to college students. To overcome these barriers, the current study designed and evaluated Your Self-Compassion Companion, a ChatGPT-powered AI chatbot intervention grounded in self-compassion theory and delivered over three weekly 20-min …

Nicotine Aerosol Self-Administration And Reward Potentiation: Using A Preclinical Model Of Vaping To Investigate The Stimulus-Enhancing Properties Of Nicotine, Kiernan T. Callister

All Graduate Theses and Dissertations, Fall 2023 to Present

Tobacco use is the leading cause of preventable disease and death in the United States and worldwide. Nicotine, the primary component of tobacco, is responsible for the addiction to tobacco and nicotine products, such as Electronic Nicotine Delivery Systems (ENDS). The widespread consumption of these products is motivated by several complex properties of nicotine, such as its ability to increase the rewarding value of stimuli in the environment. Although reward enhancement has been demonstrated via smoking and other forms of nicotine intake, it is unclear if these effects extend to electronic cigarettes. The present study used an animal model of …

Pavlovian Conditioning And Self-Control: From Laboratory To Classroom Application, Saba Mahmoudi

All Graduate Theses and Dissertations, Fall 2023 to Present

Impulsive choice, the preference for a smaller-sooner reward (SSR) over a larger-later reward (LLR), is associated with various challenging behaviors (e.g., gambling and substance-used disorders). Many interventions can reduce impulsive choice but those that produce long-lasting effects typically require long training durations or are difficult to implement in applied settings. This dissertation evaluated a novel Pavlovian training approach designed to promote self-control. In Experiment 1, procedures from Mahmoudi and Madden (2024) were replicated in the laboratory with the addition of a truly random control group. The study also assessed whether presenting the conditioned stimulus (CS) before a choice would increase …

Effects Of Single-Session Interventions On Youth Internalizing Problems, Thomas K. Franzmann

All Graduate Theses and Dissertations, Fall 2023 to Present

Anxiety and depression are among the most common mental health concerns young people face, and they often interfere with school, friendships, family life, and long-term well-being. Even though effective therapies exist, only about half of youth who need care ever receive it, and among those who do start treatment, the most common total number of sessions a young person attends is one. This gap between what young people need and what they actually receive raises a practical question for the field: can a single, well-designed meeting with a provider produce meaningful change for some youth and families, and what should …

Mindful Classrooms: Teachers Co-Designing And Implementing Mindfulness Interventions, Mary L. Phan

All Graduate Theses and Dissertations, Fall 2023 to Present

Teachers play a critical role in supporting student learning and well-being, yet many experience high levels of stress, burnout, and increasing job demands. Stress can negatively affect teachers’ mental health, job satisfaction, and classroom environments, making it important to identify practical and sustainable ways to support teacher well being. Mindfulness practices, which encourage individuals to focus on the present moment with awareness and acceptance, have shown promise for reducing stress and improving emotional well-being. However, little is known about how mindfulness programs can be adapted to fit the realities of elementary school classrooms and whether teachers can successfully implement these …

Affective And Cognitive Factors Contributing To Male-Female Differences In Mathematics, Sarah N. Herod

All Graduate Theses and Dissertations, Fall 2023 to Present

Math differences between men and women have been studied for several decades, with original theories suggesting a biological reason for the differences and more new ones suggesting multiple factors, such as self-efficacy, anxiety, and spatial ability, may be responsible for these apparent differences. Additionally, most research into math differences between the sexes involves the use of a composite score, rather than examining the different sub-domains of math separately. The purpose of the current study was to examine the relationship between sex and math performance within the context of an individual's belief and attitudes towards math and spatial information. Seventy-one participants …

Heart-Rate Variability As A Stress Reactivity And Recovery Biomarker In Sensory Processing Sensitivity, Jordan Kenemore

Theses and Dissertations

Sensory Processing Sensitivity (SPS) is a temperament trait characterized by greater environmental attunement and deeper cognitive-emotional processing. Though associated with heightened emotional reactivity, the physiological mechanisms of SPS remain unclear. This study tested whether SPS is associated with parasympathetic nervous system (PNS) functioning, indexed via heart rate variability (HRV), during rest, stress, and recovery. A sample of 274 female undergraduates completed the Highly Sensitive Person Scale and participated in a laboratory stress protocol involving a resting baseline, a psychosocial stressor (the Montreal Imaging Stress Task), and a recovery period. HRV was measured via electrocardiogram and quantified using RMSSD and high-frequency …

Understanding Parent Training In Aba: Bcba Perspectives On Professional Training, Manualized Programs, And Cultural Humility, Alyssa Nicole Fuentes

Theses and Dissertations

Parent training is a critical component of Applied Behavior Analysis (ABA); however, limited research has examined how Board-Certified Behavior Analysts (BCBAs) prepare to deliver culturally responsive parent training. The purpose of this qualitative study was to explore BCBAs' experiences with professional training, manualized parent training programs, cultural humility, institutional influences, and parent training practices when working with families of children with autism spectrum disorder (ASD), with particular attention to Latinx families. Eight BCBAs practicing in the Rio Grande Valley of Texas participated in semi-structured interviews conducted via Zoom. Interviews were analyzed using a hybrid Applied Thematic Analysis (ATA) approach that …

Addressing Emotional And Behavioral Difficulties At An Innovative Alternative Education Program: An Exploratory Study Of The Efficacy Of A Culturally Adapted Dbt Skills Group, Amanda Amber Palomin

Theses and Dissertations

Disciplinary alternative education programs (DAEPs) serve to provide students with an alternative option to the traditional schooling environment. Adolescents who are enrolled into DAEPs often experience behavioral and emotional difficulties, such as substance use and disruptive behaviors which are often influenced by difficulty with emotion regulation. If emotion regulation difficulties are left unaddressed, students are likely to be re-enrolled into DAEP’s due to subsequent school conduct violations. In school settings, social emotional learning opportunities, such as therapy groups, are often offered to address these emotional and behavioral difficulties. This study aimed to explore the effectiveness of a culturally adaptive dialectical …

The Effects Of Sexual Orientation Stereotype Information And Prejudice On False Memories, Source Monitoring Errors, And Social Categorization Judgments, Julia Belen Strickland Nunez

Psychology Theses & Dissertations

Minoritized groups, such as the LGBTQ+ community, receive many harmful and destructive stereotypes from others. These negative views affect minorities because when people are recalling a memory, they fill in the gaps with general information that they know. When the schematic information is not accurate, people tend to remember information that was not originally presented; this is known as a false memory. When people accurately recall a memory, but not the source of the memory, it is known as a source monitoring error.

The current study investigated whether stereotype-consistent information leads to more false memories and source monitoring errors as …

Examining The Relationships Between Apathy Subdomains, Heart Rate Variability And Cognitive Performance, Yasmin Bahai Nabulsi

Psychology Theses & Dissertations

Apathy, defined as a reduction in motivation and goal-directed behavior, is a multidimensional neuropsychiatric syndrome encompassing behavioral, executive, and emotional components. Although heart rate variability (HRV) has been linked to depression and executive functioning, its relationship with apathy remains unexplored. The present study examined associations between apathy subtypes, resting HRV, HR and HRV reactivity, and cognitive performance. A sample of 116 healthy young adults completed self-reported measures of apathy, depression, fatigue, reward sensitivity, and attentional control. Electrocardiography (ECG) was used to assess resting HRV, followed by continuous recording during cognitive tasks, which included the Digit Span Test and a verbal …

Retention During Turbulent Times Of Higher Education: Modeling Intent To Leave Academia For Research University Faculty, Jordan Monroe Ball

Psychology Theses & Dissertations

University faculty operate as the lifeblood of any institution given that their job requires a “double duty” to develop both scholarly research and student minds. Due in large part to these expectations, research shows a long history of poor mental health for faculty, which ultimately results in faculty turnover. One model of faculty work motivation (Padilla et al., 2023) details the way in which the faculty work environment influences their mental health, and subsequently informs their job satisfaction, organizational commitment, and intent to leave academia, which serves as a proxy for turnover. Retention related issues have not been a pressing …

Exploring The Experiences Of Women In Mental Health Therapy After The Occurrence Of Perinatal Loss, Courtney Allison Nishnick

Counseling & Human Services Theses & Dissertations

Perinatal loss encompasses losses of pregnancies at any gestational age, as well as deaths occurring within one year post-birth. In the United States, around 40 thousand stillbirths and infant deaths occur every year (Ely & Driscoll, 2025; Gregory et al., 2025), with about 23 million miscarriages also occurring annually worldwide (Quenby et al., 2021). Perinatal loss experiences lead to distressing mental health symptoms not limited to anxiety, depression, posttraumatic stress, and grief (Crockett et al., 2019; Wamser & Ferro, 2025). While there is extensive research on perinatal loss as it pertains to medical context, there is minimal research relating to …

Switches And Witches: Exploring The Relationships Between Religious Struggles, Spiritual Beliefs, And Well-Being, Emma J. Trierweiler

Psychology Theses & Dissertations

This study examined the mechanisms between interpersonal and doubt-related struggles and well-being outcomes in a formerly religious sample. The focus of this dissertation was to analyze the mediating roles of disengagement from God and perceived social support. Approach toward God was also examined as a control but not specified to be connected to the well-being outcomes given the emphasis on formerly religious individuals’ experiences. This was a retrospective study, where participants were asked to consider their responses as they relate to the time they were pulling away from religion. Three measures of well-being were explored using structural equation modeling. Positive …

Relating Profiles Of Mental Health And Psychosocial Stressors To Health-Harming Behaviors Among College Students: Differences Across Race And High-Effort Coping, Rachel Ayala Guzman

Psychology Theses & Dissertations

Black Americans experience disproportionately poorer physical health outcomes than White Americans despite often reporting comparable or better mental health, a phenomenon known as the Black–White mental health paradox. High-effort coping (HEC), a culturally relevant coping style characterized by working harder in the face of adversity, has been proposed as a potential factor underlying this paradox. However, little is known about how HEC relates to mental distress and health-harming behaviors among college students, a population at elevated risk for both mental health issues and health-harming behaviors. This study used a person-centered approach to examine profiles of mental distress and psychosocial stressors …

Drinking Group Injunctive Norms: An Event-Level Examination, Karolina Kazlauskaite

Psychology Theses & Dissertations

College students are at increased risk for negative alcohol-related outcomes. Theoretical and empirical support suggest that peer groups play a crucial role in college student alcohol use, in part because they establish normative values and behaviors (i.e., norms) that members follow. Research indicates that those who identify more strongly with a group are more likely to embody that group’s values—particularly regarding drinking. Notably, injunctive norms, or perceptions of peer permissibility toward drinking, predict individual drinking outcomes, such that perceiving one’s peers as more approving confers additional risk for personal drinking. However, prior examinations of injunctive norms have not assessed perceptions …

Social Workers’ Lived Experiences Of Trauma-Informed Training, Ashley Ann Johnson

Walden Dissertations and Doctoral Studies

Social workers report limited formal training in trauma-informed approaches, and implementation of trauma-informed care varies widely across settings, with inconsistent training uptake and organizational support for sustained practice change. The purpose of this qualitative phenomenological study was to explore the lived experiences of social workers in trauma-informed training. The study was guided by trauma-informed care principles and an experiential learning framework. The research question examined how social workers develop trauma-informed competence and how systemic factors influence practice. Data were collected through 11 semi structured interviews with social workers and analyzed using thematic analysis. Three key themes emerged: (a) trauma-informed competence …

The Representation Of Suicide In Spanish Teen Fiction Tv Series: Narrative Trends And Media Literacy Implications, Patricia Palomares-Sánchez, Victoria Soto-Sanz

Journal of Media Literacy Education Pre-Prints

The present study analyses the narrative treatment of suicide in Spanish youth fiction television series produced between 2015 and 2024, aiming to identify representation trends in relation to the recommendations for responsible media coverage and their implications for media literacy. The methodology underpinning this study encompasses eight fiction TV series and combines quantitative research, derived from data collection and analysis, with a qualitative component, focusing on the interpretation and analysis of the results. Findings indicate that the representation lacks due caution in depicting the method and location of suicide, which increases the risk of imitation. Although the narratives present alternatives …

A Systematized Review Of The Effectiveness Of Sbirt On Reducing Adolescent Substance Use In School Settings, Mallory L. Mcivor

Educational Specialist, 2020-current

As substance use remains a pressing public concern for adolescents, the academic, social, and neurological consequences are extensive. Schools are uniquely situated to support large populations of youth during their critical developmental periods, and schools act as the ideal location for substance use prevention and intervention. This study explored the prevalence and influence of substance use on adolescents, the role of school climate in prevention and intervention efforts, and assessed the model Screening, Brief Intervention, and Referral to Treatment (SBIRT) as a suitable framework for school-based interventions. Following a structured search across two databases, 20 studies met inclusion criteria and …

Effects Of Exposure To Opposing-Party-Aligned And Same-Partyaligned News On The Tone Of Cross-Cutting And Intraparty Online Political Discussions, Alexa Chen

Electronic Theses and Dissertations 2020 - Present

Five-hundred twenty-one participants completed an online study to assess the effects of exposure to highly polarized news sources on the tone of intraparty and crosscutting political discussions. Participants watched five randomly selected news clips from Fox News or MSNBC and then completed a discussion task with an AI chatbot. News clips were matched by tone and topic across news sources and each participant watched the same number of positive, negative, and neutral news clips. Participants were randomly assigned to engage with one of two chatbots: the liberal chatbot or the conservative chatbot. Semantic analysis was conducted via LIWC-22 to produces …
