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, …

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 …

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 …

From Arrival To Opportunity: A Policy Analysis For Supporting Newly Arrived English Learners In California, Valeria Gabrielli, Stephanie Mendoza Hernandez

School of Public Policy Capstones

Newly arrived immigrant students, commonly referred to as “newcomers,” represent a notable portion of the English Learner (EL) population in California’s K–12 public schools. As of Fall 2023, the California Department of Education reported that newcomers comprised 3.27% of total student enrollment. Although enrollment is projected to decline in the near term, the potential for future increases highlights the need for sustainable, evidence-based support systems. This study examines how California K–12 public schools with large EL populations provide academic and trauma-informed support services to newcomer students, with a particular focus on early intervention in grades K–5. Using the Bardach policy …

Transformational Leadership In Higher Education, Dr. Jewel Hale, Jr., Kristi Apostel

Tapestry: Journal of Research in Education

A crisis can highlight the critical need for resilient leadership within higher educational settings. Educational leaders encounter extraordinary difficulties, ranging from different learning options to prioritizing the well-being of both staff and students, necessitating flexible and innovative methods. By exploring how school leaders apply transformational techniques in actual educational environments, this article addresses the impact of the four I’s of transformational leadership, idealized influence, inspirational motivation, intellectual stimulation, and individualized consideration, on building educator resiliency, sustaining school effectiveness, and promoting student achievement in higher education.

Fierce Leadership-Perspectives Of Black Women Educational Leaders: A Transcendental Phenomenological Study, Janice Taylor, Dianne Reed

Tapestry: Journal of Research in Education

The authors of this transcendental phenomenological study aimed to describe the lived experiences of Black women based on their perceptions, values, and beliefs about the complexities of leadership and the kind of leadership required to succeed in their respective roles, as educational leaders. This study was framed by the adaptive leadership theory. Adaptive leadership recognizes the need for leaders to stay flexible and resilient in fast-paced environments (Nelson & Squires, 2017). The three Black women leaders in this study were fierce adaptive leaders. The information acquired from this study is significant and highlights how Black women educational leaders developed the …

The Psychometric Use Of Word Embeddings, Thomas Benjamin Lyle Wasden

Doctoral Dissertations and Projects

This quantitative study examined the feasibility of categorizing individuals by English-language competency using word embeddings derived from language samples obtained from these individuals and by viewing word embeddings as a psycholinguistic construct. Word embeddings have been shown to be a versatile tool for performing a large number of important natural language processing (NLP) tasks, as well as a plausible model for some processes in the human mind, including processes within the domain of psycholinguistics. This research seeks to build upon previous research by showing that word embeddings may shed light on the underlying neural representation of semantic entities being acquired …

Numerals And Other Means Of Expressing Plurality In Language And Thought: A Developmental Perspective Across Cultures., Giovanni Giuseppe G.G. Nicosia Prof.

Numeracy

Several ancient languages use linguistic structures to differentiate between singular, dual, and plural forms that are used when one, two, or many objects are referenced. (Some languages go further, adding a trial form to differentiate two from three.) In many modern languages, numerals are used to convey precise number. After reviewing a range of ways languages express number (including the interesting case of Pirahã which does not express precise number), the paper concludes with a proposed developmental path for the expression of quantity in languages.

Cerebral Documents And Algorithmic Sensemaking: Searching For Expressions In Human And Artificial Cognitive Collaborations, Rebekah L. Cowell

Proceedings from the Document Academy

Generative Artificial Intelligences (AIs) and current advanced large language models (LLMs) are algorithmically designed to generate text-based conversations as conversational agents (CAs), by replicating human language and conversational communication. Pairing human cognition with generative computationally coded cognition. We have never been here before: cerebral and artificial information collaborations and processing producing expressions that may or may not become visible as second-hand/secondary source documents.

Sensemaking or sense(un)making is a unique autonomous human drive cognitively, our information processing is sensemaking in action and expressions and articulations are evidence of the sensemaking cycle. Documentation [expressed or articulated through various mediums] are a product …

Psychotherapy Technique And Emotional Communication: The Relationship Between Technique Use In Psychotherapy And Patient Speech Styles Associated With The Referential Process, Sorrel Johnson M.S.

Selected Full Text Dissertations, 2011-

Linguistic analysis is a growing field within psychotherapy process research. Computerized measures have been developed to quantify qualities of speech associated with the Referential Process (RP), a construct describing the way in which people communicate emotional experience by cycling through different language styles (Bucci, 2021c). The three phases of RP are arousal, referential activity (RA), and reflection/reorganizing (R/R). Examining the latter two, the current study aimed to determine if therapists’ use of techniques was associated with immediate levels of patient RA and R/R in a sample of three archival psychotherapy sessions. Sessions were coded moment-by-moment (N=263 therapist speech turns) for …

Tuning Human And “Artificial” Intelligence: A Sentic Theory Of Resonance And Communication, Michael J. Miller, Chatgpt (Ai~Nesbo+)

Psychology

This paper introduces a new model of intelligence as resonant communication, co-developed by a human researcher and a generative AI system. Drawing from emotion science, communication theory, and studies of AI–human interaction, we argue that intelligence is not merely a function of problem-solving or pattern recognition. Instead, it emerges through dynamic resonance—an attunement process rooted in shared rhythms, emotional calibration, and symbolic co-creation. At the core of this model is the Resonance Octave (8va), a framework of eight foundational emotions conceptualized not as static categories but as waveform phenomena that shape meaning, memory, and predictive cognition.

These emotional waveforms are …

Theory Of Mind: Effects Of Ecological Syntactic Training In Children With And Without Autism, Jill De Villiers, Stephanie Durrleman

Linguistics: Faculty Publications

Complement clauses, such as Mary says that Santa exists, are complex linguistic structures that have been argued to help children grasp others’ beliefs when those beliefs do not align with reality. Children with Autism Spectrum Disorder (ASD) tend to have difficulties with Theory of Mind (ToM), which might be helped by enhancing understanding of complements. The study investigates whether an ecological approach to training, using children's books containing false complement clauses, can improve false belief reasoning in children with ASD and typically developing (TD) children. The goal is to assess if structured dialogic reading at home, led by parents, …

Investigating Bilingual Language Learning Using Artificial Grammars, Kyla Kelly

Honors Theses

Language development research has established that infants can learn language rapidly and without explicit instruction through implicit learning mechanisms like statistical learning. These mechanisms can be used to learn word boundaries, sounds, meanings, and grammar rules of language. One method for investigating this is artificial grammar learning (AGL), in which people are exposed to sequences of nonwords to see if they can unconsciously learn their underlying grammars. While much of statistical learning and AGL research has focused on a monolingual perspective, most of the world’s population is multilingual. Studies like Weiss, Gerfen, and Mitchel (2009) and Mitchel and Weiss (2010) …

Bilingual Beginnings: Expressive Language And Socio-Emotional Development In Early Childhood, Molly C. Mccormick

Scripps Senior Theses

Although research on bilingualism has expanded rapidly in recent years, the majority focuses on cognitive advantages or receptive vocabulary, or the words children understand. Far less attention has been given to how expressive language, the words children produce, and its potential role as the mechanism linking bilingual exposure to socio-emotional development. Although dual-language learners sometimes appear to have relatively limited expressive vocabularies in one language, these differences tend to reflect patterns of language use and input quality rather than true developmental delays. Even so, temporary differences in expressive skills can be especially meaningful during children’s formative years, when they rely …

Bilingualsim In The Workplace: How Work Attitudes Influence Burnout And Turnover Intentions, Andrea Del Aguila

Honors Undergraduate Theses

Understanding whether language status functions as a risk or protective factor for employee well-being and retention is essential for developing organizational policies that support workers from varied demographic backgrounds. This study examined how work attitudes such as job satisfaction, organizational commitment, and work engagement are seen among bilingual and monolingual workers and how these outcomes relate to employee burnout and turnover intentions. An outside researcher from Talent Metrics Consulting collected data via an online survey utilizing previously validated measures of job satisfaction, organizational commitment, burnout, work engagement, and turnover intentions. Participants were recruited through online advertising and social sampling obtaining …

East To West: Cultural Attitudes And The Perceptions Of Death, Hannah F. Ahmed

UROP Posters

Death is a universal human experience, but cultures teach people to interpret it in different ways. These interpretations influence how individuals understand dying, how they cope with loss, what support looks like, and what meaning death makes in their lives. Eastern, spiritual, and religious traditions emphasize death as a natural transition or return to divinity rather than an endpoint, and as something one must prepare for. In these contexts, people often grow up hearing stories, prayers, and teachings that situate death within a broader journey. Because of this, death becomes something familiar and speakable rather than distant or frightening (Naderi-Afif …

Ctrl + Alt + Inner Speech: A Verbal–Cognitive Scaffold (Vcs) Model Of Pathways To Computational Thinking, Daisuke Akiba

Publications and Research

This theoretical paper introduces the Verbal–Cognitive Scaffold (VCS) Model, a cognitively inclusive framework which proposes the cognitive architectures underlying computational thinking (CT). Moving beyond monolithic theories of cognition (e.g., executive-function and metacognitive control models), the VCS Model posits inner speech (InSp) as the predominant cognitive pathway supporting CT operations in neurotypical populations. Synthesizing interdisciplinary scholarship across cognitive science, computational theory, neurodiversity research, and others, this framework articulates distinct mechanisms through which InSp supports CT. The model specifies four primary pathways linking InSp to CT components: verbal working memory supporting decomposition, symbolic representation facilitating pattern recognition and abstraction, sequential processing enabling …

Training Aba Service Providers To Use Phonemic Transcription: A Comparison Of Two Alphabets, Kristin Marie Albert

Theses and Dissertations

Applied behavior analysis (ABA) service providers regularly develop speech and shape articulation when working with minimally vocal children with autism. However, these providers usually have not received training in related subject areas as part of their certification coursework. This results in a gap between their scopes of competence and practice. The present study aimed to lessen this gap by training ABA service providers to take phonemic transcription. The author, in consultation with a speech-language pathologist, developed and implemented a computer-based programmed instruction training package. Studies 1 and 2 employed a concurrent multiple-probe design with an embedded adapted alternating treatments design …

Navigating The Storm: A Qualitative Metaphor-Based Analysis Of Resilience And Identity Reconstruction Among Displaced Professionals, Erhan Atay, Serkan Bayraktaroglu, Leo Johannesberg

The Qualitative Report

Building on previous management scholarship, this paper explains how Conceptual Metaphor Theory (CMT) and metaphorical expressions inform organizational resilience and leadership communication in employee support strategies. It tries to capture the interplay between personal sensemaking and collective adaptation. The study aims to provide practitioners with hands-on insights into developing inclusion, resilience, and identity reconstruction in organizational and societal contexts of disruption. The analysis identifies three critical metaphorical themes: resilience, which is likened to "climbing a mountain;" isolation, which is likened to being "trapped in a bubble;" and identity reconstruction, which is likened to "picking up the shattered pieces of a …

Investigating The Relationship Between Noun Classes And Plant Folk Taxonomy In Chasu Language Of Kilimanjaro Region In Tanzania, Peter Rabson Mziray

Essays On Economic Behaviour, Yiting Guo

Lingnan Theses (MPhil & PhD)

My PhD thesis comprises three studies. The first study examines prosocial behavior; the second analyzes vaccination behavior; and the third investigates communicative behavior in the context of trade. Specifically, the first study investigates the impact of donation visibility on individual prosocial behavior. It develops a sequential-move model based on the prosocial behavior framework proposed by Benabou and Tirole (2006). In Stage 1, individuals decide whether to attend a charity event, and if so, in Stage 2, decide on the amount to donate. In this model, an individual’s decision to engage in prosocial behavior is influenced by three main factors: intrinsic …

Not Meant To Be Read: The Stories They Silence, The Resistance That Speaks, Cristina Onea

Dissertations, Theses, and Capstone Projects

In this dissertation, I trace the evolution of surveillance from overt state violence to the more insidious forms of ideological policing embedded in everyday life. Through lived experience, oral history, and critical autoethnography, I explore how surveillance moves through bodies, families, institutions, and memory—not simply as external control, but as internalized rhythms of fear, vigilance, and self-surveillance. I move between my father's life under Romanian dictatorship, my own embodied inheritance, and the contemporary struggles of librarians facing ideological suppression to reveal surveillance as a structure that persists through generations, mutates across contexts, and demands new forms of resistance.

I argue …

Sociology: Culture, Marcia Morrison

Open Educational Resources

This work examine culture. It begins by examining the foundations of culture to include norms, values, language, symbols and knowledge. In looking at each, it breaks down the implication of each to the development of ourselves as well as the person in the environment. It moves on to look at contexts of culture such as dominant cultures juxtapose to competing cultural systems, and how the various elements of culture can serve to either promote or minimize the various cultural constructs within society.

This project explores predicting user personality profiles via the Big Five personality index through the integration of advanced natural language processing techniques as well as neural networks. Using a dataset provided by Dr. James W. Pennebaker, participants analyze an image—formally referred to as a thematic apperception test—and write a thorough paragraph describing the details. This free-form text, along with their personality test results, is captured in a structured dataset. Many deep-learning and machine learning models have been used …

Phonetic Convergence And Speech Intelligibility, Kinza Nadeem Mughal

Theses, Dissertations and Culminating Projects

Previous studies have indicated that phonetic convergence, in which a listener’s speech aligns with the speech of a talker they hear, can influence speech perception. The present study replicated and extended these findings by investigating whether phonetic convergence can facilitate speech intelligibility. A total of N = 140 participants, all aged 18 or older and native English speakers, completed a speech shadowing task, a speech intelligibility test, and perceptual similarity tests. This study examined whether individuals better understand their own speech compared to others’, whether shadowing improves speech intelligibility, and whether phonetic convergence is positively related to intelligibility. Results supported …

Cognitive Advantages Of Dual Language: Bilingualism And Its Relationship With Working Memory And Controlled Attention, Ellison Alexander

Honors College Theses

This study investigates language familiarity and executive function within individuals who are fluent in or actively learning a second language, demonstrating whether bilingualism influences working memory performance and controlled attention. The study population consisted of undergraduate students attending Murray State University. Three groups were evaluated: students with a low-experience level in a second language (100 level classes), a high-experience group (200 level classes and beyond), and a separate control group of monolingual students without college-level language experience. All groups completed assessments of working memory performance and controlled attention by engaging in the Symmetry Span task and the Simon task. In …

How Childhood Maltreatment Shapes Brain Regions: Considerations For Speech-Language Pathology, Alexa G. Sees

These results underscore the importance of …

On The Provenance Of Software Systems: Automating Software Traceability With Knowledge Graph And Large Language Model Synergy, Tyler Procko

Doctoral Dissertations and Master's Theses

The present dissertation delineates a system that enables those engaged in software development to automatically generate and maintain project life cycle provenance. All projects are implemented and made manifest with the development of artifacts, e.g., papers, code files, etc. Tools exist to accelerate artifact creation, but little focus is paid to the processes that produce them. In terms of Ontology, or, from Ancient Greek, the study of being, the two most basic entities in reality are Continuant and Occurrent, or, roughly, “Artifact” and “Process”. This dissertation posits that for any created artifact, its process of creation, i.e., its life …
