Predicting Psychosis Through Speech: A Case For Nlp In Clinical Practice, Lydia Britton '27

Student Research

Psychosis is difficult to identify in early stages; however, changes in speech and language offer insights and indicators of emerging symptomatology. This paper examines the potential for Natural Language Processing (NLP) and other computational linguistic techniques for improving the predicition of psychosis disorders through automated analysis of speech. Existing research shows that lingustic markers that are aligned with Formal Thought Disorder, including reduced semantic coherence, poverty of content, tangentiality, reduced syntactic complexity, and pragmatic deficits, can help to distinguish between individuals who are experiencing or at risk for psychosis from healthy controls. Traditional clinical assessments may have difficulty identifying and …

Understanding Behavioral And Representational Divergences Of Humans And Machines, Thomas Lasman Botch

Dartmouth College Ph.D Dissertations

Human behavior and cognition are strikingly variable: people differ from one another in their preferences and abilities, and even from themselves across situations. Yet this diversity arises from common neural machinery shaped by the complex environments humans inhabit. A central objective of cognitive neuroscience is to understand how this varied experience emerges from interactions between brains, agents, and environments. In this dissertation, I argue that comparing behavior and neural computation across humans, artificial systems, and contexts is essential for understanding the flexibility of human cognition. Across three chapters, I use this comparative approach to examine how the rich, multimodal contexts …

An Equity-Based And Culturally Responsive Bill Of Rights For Early Childhood Students Of Color With Exceptionalities, Evette Simmons-Reed, Michelle Frazier Trotman Scott, Gloria Tardash, Mildred Boveda, Donna Y. Ford

Perspectives on Early Childhood Psychology and Education

The COVID-19 pandemic exacerbated existing disparities in early intervention (EI) and early childhood special education (ECSE) services for culturally and linguistically diverse (CLD) disabled children, exposing critical gaps in access, services and support. systemic inconsistencies in implementation, training, and funding, remain barriers limit opportunities for CLD students to benefit, despite the aims of the Individuals with Disabilities Improvement Act (IDEA). To address these inequities, this manuscript proposes an expanded and updated Culturally Responsive Equity-Based Bill of Rights for EI and ECSE. Building upon Ford and colleagues' (2018) work, this revised document extends protections to children aged zero to five, emphasizing …

Latent Transition Analysis: A Statistical Method For Identifying Underlying Subgroups Over Time, Holmes Finch

Perspectives on Early Childhood Psychology and Education

Researchers working in early childhood research are often interested in assessing change over time in multiple variables. In addition, they may wish to ascertain whether there exist subgroups in the data with respect to these variables, and whether/how membership in these groups is related. Latent transition analysis (LTA) provides such researchers with a useful tool for investigating questions around such groups, including their composition, frequency, and the likelihood of moving from one to another at different points in time. The purpose of this manuscript is to provide a full demonstrate of LTA and show how it can be used to …

Developmental Ecological Psychology Meets Organicist Biology: The Example Of The Ecological Self, Catherine Read

The International Journal of Ecopsychology (IJE)

In this paper we outline an ecological-organicist theoretical framework to understand human development. The ecological approach to development (Developmental Ecological Psychology, DEP) places the organism at the center and has a mutualist theoretical framework with an epistemic foundation in direct perception. While research in this tradition has paid much attention to specific developmental questions at a young age (such as perceptual learning, affordances, and action coordination), less effort has gone into the discussion of theoretical issues of overall development at the level of organism-environment mutuality. Meanwhile in biology, a new emphasis on the organism as an explanatory concept and level …

Cultural Identity In Transition: A Comparative Study Of Self-Defining Memories And Personality In American And Russian-American Students, Sebastian Parilov

CISLA Senior Integrative Projects

This study examined cultural differences in Self-Defining Memories (SDMs) and personality traits among American and Russian-American college students. Participants included 39 college students (19 Russian-American and 20 American) aged 18-24 who completed the Self-Defining Memory Task and the Big Five Inventory to test for Openness, Conscientiousness, Agreeableness, Extraversion, and Neuroticism. Memories were coded for overall themes, agency versus communion, and redemption versus contamination narratives. Results showed no significant differences between groups on overall Big Five personality traits. However, there were many differences in the two groups' memories. Russian-American participants reported significantly more positive and fewer negative self-defining memories than American …

A Content Analysis Of Emotional Valence And Engagement In Youtube Comments, Lydia Britton '27

Student Research

This study investigated the relationship between YouTube comment participation and emotional valence. We hypothesized that highly negative-valenced comments would generate higher engagement (likes and replies), based on prior research showing that emotionally intense content drives interaction. Fifty comments from ten popular videos across five categories (shopping, music, gaming, news, and sports) were analyzed using linguistic indicators (language and emojis) and intensifiers (capitalization, exclamation points, profanity). Each comment was assigned a dominant valence and a Likert scale rating. Engagement was measured by likes per view and replies per view. Results showed a negative correlation between emotional valence and replies. Despite trending …

Exploration Of Ai-Based Method Feedback For Clinical Psychology Skill Development With An Emphasis On Deliberate Practice, Beckham G. Mccord

Honors Theses

Training competent psychotherapists requires substantial time, supervision, and performance-based feedback. However, traditional methods of providing feedback are resource-intensive and difficult to sustain outside of university and research settings. Recent advances in artificial intelligence (AI) have created new opportunities to automate aspects of psychotherapy fidelity assessment and provide trainees with more frequent feedback. The present study examines the implementation of Lyssn, an AI-based psychotherapy platform that provides clinical feedback to therapists, in a graduate-level course on Evidence-Based Services. Multiple years of course data were reviewed to evaluate therapist competence, therapist behaviors, and student engagement with AI-generated feedback. Particular emphasis was placed …

Interpreting American Sign Language: A Literature Review Of Assistive Technologies, Natalie Louise Paradiso, Emma Grace Kochenderfer

Student Scholar Symposium Abstracts and Posters

American Sign Language (ASL) is a visually elaborate, spatially oriented linguistic methodology that relies on combinations of hand movements, body positioning, facial expressions, and motion/spatial perception, aspects of which make interpretation difficult for automated machine recognition. Current assistive technology approaches to ASL interpretation are generally within the categories of computer vision models (including deep learning, multi-focus image fusion, and keypoint tracking) and wearable, multimodal/sensor-based approaches (such as smart glasses and inertial-sensor gloves). Within controlled environments, computer vision models perform well. However, when applied to conditions such as non-manual signs/features, signer variability, and rapid assimilation, they falter in processing all aspects …

Supporting An Inclusive Summer Camp For Children With Developmental Disabilities Who Use Aac And Their Neurotypical Peers: A Practice-Based Report, Jessica Hicks

Communication Disorders and Occupational Therapy Undergraduate Honors Theses

For my honors research, I completed an internship in an augmentative and alternative communication (AAC) lab at the University of Arkansas. For most of my internship work, I helped support an inclusive AAC summer camp for children with and without developmental disabilities, such as autism, for whom speech does not fully meet their communication needs. AAC includes high-tech tools such as communication apps on tablets that serve as speech-generating devices (SGDs). SGDs were used by many of the AAC summer camp participants with developmental disabilities. In this report, I will provide background information on AAC and developmental disabilities. I will …

Personality Meets Possibility: Exploring Cognitive Engagement For Older Adults In A Changing World, Kalvry A. Cooper

All Theses

Engagement in cognitively stimulating activities (CSAs) is critical for maintaining cognitive health in older adults. While existing research has examined the benefits of CSAs, less is known about how factors such as personality traits, education, and technology proficiency influence engagement, especially during the COVID-19 pandemic. This study aims to explore older adults' participation in online versus in-person CSAs during the pandemic and identify key predictors of engagement. Using secondary data from the EFIT and ENACT studies, this research investigates how variables like marital status, education, personality traits, and mobile device proficiency shape older adults' decisions to engage in online or …

Negation And The Backfire Effect, Caden Fowler

Psychological Science Undergraduate Honors Theses

Quick! Do not think of a polar bear. Did you think of a white bear? As Russian author Fyodor Dostoevsky wrote in his 1863 essay “Winter Notes on Summer Impressions,” “[when tasked to not think of a polar bear] you will see that the cursed thing will come to mind every minute.” The consequence of negation without context (i.e., unlicensed negation; Levine & Hagaman, 2008) is what has come to be referred to as the “backfire effect,” a phenomenon where correcting misinformation strengthens belief in that information rather diminishing it (Ecker, et al., 2020). Fake news and misinformation in …

What Are The Roles Of Vocabulary And Working Memory In Metaphor Comprehension?, Claire Simpson

Psychological Science Undergraduate Honors Theses

One of the most notable factors that influence sentence comprehension is the presence of metaphors (e.g., Inhoff, Lima, & Carroll, 1984). The metaphor interference effect (MIE) is a very interesting result of metaphor comprehension. It is a well-known linguistic effect (e.g., Al- Azary et al., 2021; Glucksberg et al, 1982) that can result in participants taking longer to determine that a metaphoric statement is false compared to other non-metaphoric literally false statements. The present study investigated the impact that vocabulary knowledge, working memory capacity, and memory load have on the metaphor interference effect. We predicted that each of these characteristics …

Unveiling Embodied White Supremacy: Therapists’ Experiences And Its Imprint On Therapeutic Relationships In Dance/Movement Therapy, Melody E. Gamba

Counseling and Psychology Dissertations

This qualitative, arts-informed research study explored how White-identifying dance/movement therapists experience and articulate their awareness of embodied White supremacy within therapeutic relationships. Grounded in critical race theory, relational-cultural theory, and embodied critical transformation theory, the study addressed a gap in dance/movement therapy literature concerning how White supremacy is not only cognitively understood, but also somatically felt, relationally enacted, and professionally navigated. The purpose of the study was to understand how White-identifying dance/movement therapists perceive, kinesthetically experience, and make meaning of embodied White supremacy in therapeutic practice, and to explore how these embodied experiences influence therapeutic presence, attunement, and the potential …

Utilizing Brain Computer Interfaces That Interact With A Virtual Keyboard, Skye Lilienthal

Honors Theses

A brain-computer interface (BCI) can allow someone to utilize electrical signals in their brain to complete tasks using a computer. BCIs can help people take advantage of technology to type without the need for a traditional keyboard setup. This paper used the OpenBCI Mark IV to test the effectiveness of non-invasive BCIs with dry electrodes within the OpenViBE P300 Speller. This paper shows how to use the P300 speller through a setup pipeline. Results indicate that electrode placement affects P300 accuracy and that areas related to visual processing improve accuracy, suggesting that P300 signals can be detected within OpenBCI Mark …

Some Equivalence Statements Are Metaphors, Malik A. Terry

Theses and Dissertations

Metaphors work best when topic and vehicle come from different domains. Glucksberg (2011) observed that same-domain statements ( "Cats are dogs") lack metaphorical interpretations, and Experiments 1 and 2 confirmed this. Prasada (in press) proposed that minority framing ( "Some cats are dogs") enables such metaphors. Experiment 3 confirmed this.

Ai In Wonderland, Bodj Oliver Alngohuro

Honors Scholar Theses

Studies in sound symbolism have revealed a baseline preference for people to associate certain sounds with certain concepts. The Bouba/Kiki effect, for instance, reveals a preference for individuals to associate “Bouba” with a round shape and “Kiki” with a sharp shape (Köhler 1929). Other studies have revealed other associations with certain sounds and names with concepts, such as “Mil” referring to something small and “Mal” referring to something big (Sidhu and Pexman, 2017). This study looks at LLMs and how they compare to humans concerning intuitions for certain names based on sound symbolism.

The Impact Of Framing Effects And Moral Values On Prosocial Engagement, Olajuwon Olagbegi

Dissertations

Framing effects can shape perceptions, beliefs and behavior, particularly in prosocial contexts. The current study examined how language framing (social justice, social activism, volunteerism) and moral values influence interest in prosocial engagement across low- and high-cost helping scenarios. Participants (N = 219) were randomly assigned to one of three framing conditions and reported willingness to help in both low- and high-cost situations. They also completed the Moral Foundations Questionnaire. Replicating prior work (Olagbegi and colleagues, 2024), participants were more willing to engage in low- than high-cost helping. Across conditions, social justice framing elicited the greatest willingness to help. Higher fairness …

Attitudes, Behaviors, And Co-Workers Influence Of Those Who Provide Mental Health Support Services To Refugees And Immigrants., Irene Boamah

Doctor of Social Work Capstone Projects

ABSTRACT

ATTITUDES, BEHAVIORS, AND CO-WORKERS INFLUENCE OF THOSE WHO PROVIDE MENTAL HEALTH SUPPORT SERVICES TO REFUGEES AND IMMIGRANTS

Irene A. Boamah

April 3, 2026

Refugees and immigrants face a variety of mental health issues, including post-traumatic stress disorder (PTSD), depression, and anxiety. Despite these mental health issues, there is limited research examining the attitudes, behaviors and coworkers’ influence on those who provide mental health support services to this population. This study examines the relationships between the demographic and professional characteristics of mental health support service providers in Kentucky and the stigmas they may have toward refugees and immigrants.

Raising Resilient Children: Parent Video Guide To Support Children’S Emotional Development, Perla F. Nunez-Chavez

Electronic Theses, Projects, and Dissertations

Social-emotional learning (SEL) in early childhood plays a critical role in

children’s ability to recognize emotions, regulate behavior, build relationships,

and succeed in academic settings. During the preschool years (ages 3–5),

children experience rapid emotional development and rely heavily on parents for

co-regulation, emotional modeling, and guidance. Research consistently shows

that when parents engage in emotion coaching practices, such as labeling

feelings, validating emotions, and modeling regulation strategies, children

demonstrate stronger emotional competence and improved developmental

outcomes. However, despite strong evidence supporting parent involvement in

SEL, many existing interventions are delivered through structured, in-person

programs that are often inaccessible to …

Game On! Level Up Your Teaching: A Digital Game-Based Learning Guide For Preschool Teachers, Scarlett Flores Marin

Electronic Theses, Projects, and Dissertations

Although digital game-based learning (DGBL) has emerged as a

promising technological advancement in early childhood education by offering

many developmental benefits for children, its effective implementation remains a

challenge. The integration of digital technologies in early childhood education has

led to the growing use of DGBL as an effective instructional approach with

research indicating that well-designed educational apps and games can enhance

young children’s cognitive, literacy, and social development by promoting active,

meaningful, and interactive learning experiences. DGBL encourages problem-

solving, critical thinking, and collaboration, aligning with how children naturally

learn through exploration and engagement. When used intentionally, technology

and …

Investigating Racial And Ethnic Differences In Help-Seeking Recommendations And Intentions For Posttraumatic Stress Symptoms And Symptom Clusters, Josselyn Yanisbeth Telule

Master's Theses

Racially and ethnically minoritized (REM) communities experience disproportionate exposure to adverse events, including discrimination, socioeconomic disparities, justice system involvement, and limited access to healthcare. These inequities increase the likelihood of experiencing potentially traumatic events (PTEs) and developing trauma-related mental health concerns such as posttraumatic stress symptoms (PTSS). Despite this elevated risk, REM populations consistently underutilize mental health services. Although several explanations have been proposed—including differences in symptom recognition, perceived need for care, cultural values, mental health literacy, and preferred sources of support—less research has examined racial and ethnic differences in help-seeking intentions (HSI) and help-seeking recommendations (HSR), particularly in response …

Using Large Language Models To Assess Entrepreneurial Personality In Generation Z College Students, Xianyong Wang

All Dissertations

As entrepreneurial personality (EP) plays a critical role in Generation Z’s (Gen Z) long-term success, it is crucial to understand the EP of Gen Z college students. To date, little is known about what EP is and how it can be assessed in Gen Z. Therefore, this dissertation presented two sequential studies to address two closely related research foci. The first study examined the scope and dimensionality of EP in Gen Z college students using topic modeling. In the second study, pre-trained LLMs were fine-tuned to predict self-reported EP levels from personal narrative responses. To collect data, college students (N …

From Clicking To Committing: Psychological Distance And Persuasion In Online Animal Adoption Platforms To Enhance Shelter Visitation, David Goodweather

Graduate Theses and Dissertations (2019 - present)

Online animal shelter platforms have become a primary channel through which potential adopters view and evaluate adoptable animals, yet many users do not progress from online engagement to visiting a physical shelter. The dissertation examines how online pet viewing translates into intention to book a shelter visit by focusing on the roles of psychological distance and persuasive influence cues within a high-involvement decision context. Drawing on Construal Level Theory and persuasion research, a sequential process is proposed in which sustained interaction with pet profiles reduces distance-related abstraction, increasing receptivity to influence cues that facilitate movement from initial assessment to action. …

We Are Fundamental (Somos Fundamentales): Examining The Perceptions Of Dei Initiatives Among First- And Second-Generation Latino Migrant Workers, Hector Aguilar

Electronic Theses, Projects, and Dissertations

Regarding organizational literature, diversity, equity, and inclusion (DEI) has been a topic of considerable interest due to an abundance of minority groups in the workforce, who are typically targeted by DEI policies. Within minority groups are migrant populations which make up a great deal of the working population, with Hispanic workers also accounting for a significant portion of that workforce. Organizational literature has had a great underrepresentation of the Hispanic working population who are an imperative group to study to better understand their attitudes, behaviors, perceptions, and outcomes, based on organizational DEI approaches. This can help promote researchers and organizations …

Language Control Over Structural Representation In Bilinguals, Anahy Barragan-Diaz

Open Access Theses & Dissertations

In daily life, bilinguals sometimes speak each of their languages in situations where the other language cannot be understood. To avoid saying words in the wrong language in such situations, bilinguals inhibit lexical representations from the non-target language (Green, 1998). But do they inhibit structural representations? This study investigated how inhibitory control operates over structural representations in English-dominant Spanish-English bilinguals via a picture description task. An experimental group was asked to describe dative-eliciting pictures in English (Baseline Phase), followed by dative pictures in Spanish (Manipulation Phase), and once again dative pictures in English (Target Phase), while a control group followed …
