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 …

Eeg Studies Of Pre-Stimulus Activity During Turn-Taking In Naturalistic Conversation, Seyedmohamadreza Manzourolajdad

Student Works (2020-2029)

This study integrates conversational analysis principles and neural activity to investigate natural cognition and examine event-related brain changes. A wireless electroencephalography (EEG) device was used in an ecological validity setting to analyse pre-stimulus brain activity preceding conversational turns. This study aims to identify aspects of the conversation that reflect its naturalness in the aspect of listening and the corresponding brain activity by analysing the signals before and after a turn in a conversation. This research contributes to an ecologically valid understanding of natural conversation as a social action that enables seamless communication. Seven Malaysian participants (aged 19–22, M=20.46) engaged in …

Análisis Verbal De La Concordancia Negativa En Estudiantes De Español Como L2 Y Hablantes De Herencia De Una Universidad De Estados Unidos De América, Natalia C. Gallardo Linares

LSU Master's Theses

La concordancia negativa (NC) constituye un rasgo central de la negación en español, en el que un marcador negativo preverbal (no) coocurre con ítems de concordancia negativa (NCIs) posverbales, como nada, para expresar una única negación semántica. Investigaciones previas sobre la adquisición de la concordancia negativa se han centrado principalmente en el papel de la competencia lingüística y de las influencias interlingüísticas, por lo que se ha prestado relativamente menos atención a la contribución de factores lingüísticos internos, como el tipo de verbo. La presente tesis examina la adquisición de la concordancia negativa en español con especial …

Mind The Gap: Morphological Defectivity And Suffixal Competition In Polish, Szymon E. Zuberek

Dissertations, Theses, and Capstone Projects

This study investigates morphological defectivity and suffixal competition in the genitive singular of Polish masculine inanimate nouns. Drawing on survey-based grammaticality judgments from native speakers, it examines how respondents select between the suffixes -a and -u or reject both as unacceptable, thereby signaling defectivity. Mixed-effects logistic regressions revealed that defectivity was rare overall but patterned systematically by age, education, and region, with additional baseline variability across lexical items. Suffix choice showed a strong preference for -a, modulated by age, education, and region, with additional baseline variability across lexical items. These findings inform our understanding of paradigm structure, sociolinguistic variation, and …

Neutralization Mechanisms In Protest-Related Vandalism: Implications For Psycholinguistic Crisis Communication, M. Agung Lyndardi

Jurnal Kriminologi Indonesia

Protest-related vandalism has become a recurring phenomenon in Indonesia’s democratic landscape, particularly during large-scale demonstrations involving students, labor groups, and civil society coalitions. Conventional legal approaches that define vandalism as a public-order violation are insufficient to explain why such actions persist, why they concentrate on symbolic state targets, and why participants frequently deny moral wrongdoing. This article analyzes protest-related vandalism in Indonesia through the framework of neutralization theory (Sykes & Matza, 1957), integrating perspectives from criminology, moral disengagement theory, collective action, political legitimacy, and public psycholinguistics. Using a structured literature review of international and Indonesian scholarship published between 1957 and …

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 …

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

Journal of Humanities and Social Sciences

The current study investigates the relationship between noun classes and plant folk taxonomy in Chasu (G 22). The study focuses on two objectives: the first objective is to describe the plant folk taxonomy in Chasu and the second objective is to determine the relationship between noun classes and plant folk taxonomy in Chasu. Data were collected from rural villages in Same and Mwanga districts by using free listing, field interviews (jungle-walk-and-identify), and written texts containing Chasu plant names. The findings reveal that Chasu folk taxonomy reflects different ethnobotanical categories; including a unique beginner which is mmea/mimea ‘plant(s)’, and three life …

The Salience Of Function Words In Implicit Statistical Linguistic Learning: An Erp Investigation, Daniel M. Schwartz

Dissertations, Theses, and Capstone Projects

Research has indicated that children and adults can implicitly learn language patterns; however, questions still remain regarding the role and nature of implicit learning, particularly of sequential patterns. Implicit statistical learning is a type of unconscious learning of sequential patterns, which may be especially relevant to phrase structure learning. Prior studies have highlighted the differential processing of function words (FWs), such as determiners, relative to content and nonsense words and have also pointed to particular neural response patterns (specifically, Anterior Negativity, or AN) to early syntactic violations. To date, there is relatively little work directly investigating the role of FWs …

Processing Of Diphthongs By Turkish English Bilinguals: An Erp Study, Ecem Kopuz

Dissertations, Theses, and Capstone Projects

This study examines how native phonological experience influences the brain’s response to speech sounds in Turkish-English late bilinguals and English monolinguals. We asked whether neural responses reflecting encoding of auditory information would be sensitive to language specific experience. Using event-related potentials (ERPs), and specifically, the Acoustic Change Complex (ACC) we measured neural responses to four stimuli, /u/, /ua/, /iu/, and /ia/, where vowel quality changes for three of these. A change from /u/ to /a/ or /i/ to /a/ within a syllable (as in [ua] and [ia]) represents a clear vowel quality shift. All participants were expected to show sensitivity …

Usage Of Natural Language Processing And Deep-Learning Techniques On Thematic Apperception Tests To Predict Big Five Personality Traits, Blayten Jones

Electrical Engineering and Computer Science Undergraduate Honors Theses

The usage of personality as a method of behavioral prediction and outcomes of success has grown considerably over the last few decades. 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 …

Articulation As A Predictor Of Cognitive Decline, Sarah G. Hammons

Senior Theses

Background: Speech production is facilitated by motor neural networks that are proximal to neural substrates of general cognitive functions in the frontal lobe. However, the precise relationship between these brain networks supporting articulatory control and more general cognitive functioning has not been determined. A relation may be expected due to the anatomical proximity of specific networks, or due to more global aspects of brain health in individuals, affecting cognitive and motor functions across the board. Lower motor function is expected to affect the stability of speech production, but the extent to which this is also associated with lower cognitive functioning …

Unifying Comprehension And Competence Through Merge: A New Linking Hypothesis Connecting Electrophysiological Data To Linguistic Intuitions, Kevin Patrck Guzzo

Dissertations, Theses, and Capstone Projects

This dissertation integrates neuroscience and linguistics to investigate the cognitive mechanisms underlying syntactic processing. To do this, we focus on Early Syntactic Negativities (ESNs) which are rapid negative electrophysiological responses known to be elicited by phrase structure violations due to an unexpected lexical category. We examine ESNs elicited in two previously undocumented elliptical constructions, sluicing and swiping, employing event-related potentials (ERPs) and behavioral acceptability judgments. Our investigation builds upon Collins and Stabler’s (2016) formalization of minimalist syntax, proposing a novel Merge Hypothesis of ESNs. This hypothesis posits a direct link between ESNs and violations of the Merge operation, a fundamental …

Quantifying The Individual Bilingual Experience Through A Lens Of Language Dominance, Leeann Stover

Dissertations, Theses, and Capstone Projects

This article-based dissertation addresses some of the issues regarding the multifaceted nature of bi/multilingualism, focusing on the significance of individual variation in the measurement of language dominance. While age of later-acquired languages has traditionally been used to classify bilingual speakers into early and late bilinguals, the construct of language dominance has emerged as an additional criterion of classification. However, despite its utility in capturing dimensions of language experience beyond age of acquisition, the construct of language dominance has its own challenges of measurement and individual variation.

This dissertation focuses on two open-ended challenges in the quantification of language dominance: how …

Cognate Facilitation And Processing In English-Speaking Learners Of German, Kaitlin L. Young

Theses and Dissertations--Linguistics

Within the field of second language acquisition, research finds that increased exposure to input results in improved proficiency, especially when those activities are challenging yet manageable for the language learner’s current level. Because of this, listening exercises and speech processing are considered integral to language acquisition, even leading to recommendations of frequent, authentic use of the target language (TL). Instructors’ TL authenticity is, however, sometimes stunted by the demand for comprehensible input and facilitation of classroom activities; they make use of simpler syntax, stronger enunciation, and more cognates (words sharing origins, meanings, and form across languages) than in casual speech. …

The Emotional Landscape Of Aviation Pilots: Analysis Of Online Professional Forums Using Natural Language Processing, Adrienne S. Renwick, Leo Gonzalez, Charles L. Silber, Alyson Mullen, Cass Dykeman, Adam Stewart, Jennifer C. Ross, James Geisler

Journal of Aviation/Aerospace Education & Research

This study investigated burnout related to emotions in three categories of pilots: commercial passenger, commercial cargo, and military. While pilot burnout has been previously studied, challenges in self-reporting limit understanding. This study extends previous research by analyzing pilots' anonymous online forum posts to gain insight into burnout-related emotions. Natural Language Processing was conducted with the RoBERTa-base-go_emotions model, which analyzed 1,130,530 online forum posts from commercial passengers, commercial cargo, and military pilots for 27 emotion categories and one absence of emotion category (i.e., neutral). An exploratory composite score reflecting burnout-related emotional expression omnibus burnout score was calculated using seven burnout-related emotions …

Do Deaf Readers Pre-Activate Phonology During Sentence Comprehension?, Danielle Moraga, Lauren Fillet, Eva Gutierrez-Sigut, Zed Sehyr

Student Scholar Symposium Abstracts and Posters

Readers can use linguistic and contextual clues to predict upcoming words in a sentence. This predictive processing allows for more efficient recognition of upcoming words, particularly when the context of a sentence is predictable (Federmeier & Kutas, 1999; Metusalem et al., 2012). Evidence suggests that for hearing readers, preactivation of word semantics and phonology facilitates the recognition of upcoming words in a sentence (Ito et al., 2016). Readers who became deaf/hard-of-hearing before learning a language rely primarily on visual rather than auditory input, and it is unclear if they engage in similar predictive processes. The study aims to investigate the …

Enhancing Memory Through Literary Features, Sarah Naylor

Psychological Science Undergraduate Honors Theses

Literary devices used by a writer can influence and impact the manner in which readers respond and interact with a text. Both the perspectives readers are expected to take while reading and the amount of foregrounding in a text cognitively and affectively influence a reader’s experience. However, little research has explored what effects these factors have on verbatim memory. For this research, participants were instructed to read a short literary story either by identifying with the protagonist or as a spectator. After reading and completing a range of other tasks, participants were asked to select sentences they saw in the …

Preschoolers’ Generation Of Quantity Implicatures, André Eliatamby

Dissertations, Theses, and Capstone Projects

This dissertation uses the developing child as a window into the mechanisms and representations that allow us to understand the meaning of utterances in their contexts. I present three studies investigating 4- and 5-year-olds’ ability to generate two types of “quantity implicatures,” classic scalar implicatures with some that imply not all, and free choice inferences that arise with sentences like “Larry is allowed to have cake or ice-cream.” Together, the studies suggest a close relationship between pragmatic development and word learning, something not appreciated in existing literature. In the first study investigating some, I show that preschoolers interpret …

Attrition And Assimilation: The Neural Mechanisms Of Mandarin-English Bilingualism, Natalie Paige Robison

University Honors Theses

This line of research investigates attrition of native language (L1) Mandarin proficiency with increasing proficiency in English. English uses pitch to denote intonation (e.g., "it's there?" versus "it's there!"), while Mandarin additionally uses pitch to indicate word meanings; e.g., /he/ means "drink" when spoken with a high, level tone, or "river" when spoken with a rising tone. The present study delineates between two alternative explanations for the prior finding that English proficiency correlates with attrition of Mandarin tones, but not Mandarin vowels. This pattern could be explained by 1) assimilability of the Mandarin vowel contrasts used in the study into …

Prosodic Marking Of Focus In Autistic And Neurotypical Adults, Nishtha N. Trivedi

Dissertations, Theses, and Capstone Projects

Purpose: This study investigates how adult autistic speakers compare with neurotypical speakers in the manipulation of prosody to mark narrow and contrastive focus in American English. In particular, it explores whether the two groups differ in terms of pitch accent status, pitch accent type, and overall nuclear contour patterns in focus marking.

Methods: We conducted an experiment eliciting speech from autistic and neurotypical adults in which we compared their use of pitch accent in answers to wh-questions and in corrective statements.

Results: We found neurotypical speakers to primarily use H* to mark narrow focus on subjects and L+H* to mark …

Comparing Executive Control: Bilingualism's Cognitive Advantage, Malcolm Jasmin, Tonya Buchanan Ph.D.

Symposium Of University Research and Creative Expression (SOURCE)

The Stroop Task is a widely used method for studying executive control. It helps to understand cognitive processes like inhibition and attentional regulation to examine how reading text and naming colors can interfere with each other. The study intends to use the Stroop Task to explore the executive control abilities of both bilingual and monolingual individuals. Previous research has shown that bilingual individuals perform better in the Stroop test compared to those who only speak one language (Bialystok et al., 2010). The impact of this advantage is believed to be due to the need to switch between languages and prevent …

The Relationship Between Autistic Traits, Autistic Camouflaging, And Adults’ Representations Of Abstract And Social Concepts, Henry Tomiser, Katja Wiemer Dr.

Honors Capstones

Concrete concepts (e.g., BUTTON) can be experienced directly by the senses, whereas abstract concepts (e.g., FRIENDSHIP) cannot. Additionally, the mind may represent abstract concepts using more introspective, social, and emotional information than concrete concepts. Social difficulties are one defining feature of autism, and autistic individuals may use social camouflaging to hide these difficulties, but the precise nature of social processing in autism is not known. This study aims to explore possible links between autistic traits, autistic camouflaging, and mental representations of concepts. Participants gave open-ended definitions for concepts varying in concreteness and social content via an online survey. Responses were …

Gestalt Language Processing In Accredited Communication Sciences And Disorders Programs, William Harris

Master's Theses

The language development and usage of autistic individuals has become a controversial topic in many of the disciplines and professions providing support to these individuals. As a result, two theories of language processing have been proposed. Analytical language processing suggests that children process and develop language from its most simple form, a phoneme, to its most complex form, a word or phrase. However, the theory of gestalt language processing proposes that some children may instead extract larger, more complex language such as whole words and phrases first and break it down to the simpler language. Gestalt language processing is often …

Developing 240 Spanish Word Pair Stimuli For A Psycholinguistic Experiment, Francisco Villa

Student Research Symposium

Metaphors are linguistically interesting because they involve going beyond literal interpretation. For example, “night owl” can refer to an animal or a person who is active at night. Psycholinguistic researchers investigating metaphor comprehension must develop sets of stimuli (linguistic items used in experiments) that include metaphors and literal items as a baseline. One approach is to use metaphorical word pairs, because it lets researchers control several important variables, including how frequent words are within the language. For the first time, we have created a set of word pair stimuli in Spanish, which is particularly challenging because most metaphors consist of …

Biomedical Text Readability After Hypernym Substitution With Fine-Tuned Large Language Models, Karl Swanson, Shuhan He, Josh Calvano, David Chen, Talar Telvizian, Lawrence Jiang, Paul Chong, Jacob Schwell, Gin Mak, Jarone Lee

SKMC Student Presentations and Publications

The advent of patient access to complex medical information online has highlighted the need for simplification of biomedical text to improve patient understanding and engagement in taking ownership of their health. However, comprehension of biomedical text remains a difficult task due to the need for domain-specific expertise. We aimed to study the simplification of biomedical text via large language models (LLMs) commonly used for general natural language processing tasks involve text comprehension, summarization, generation, and prediction of new text from prompts. Specifically, we finetuned three variants of large language models to perform substitutions of complex words and word phrases in …

Starting Small Or Big: An Artificial Language Paradigm, Rachel Evans

LSU Master's Theses

Previous research on language acquisition has raised two competing hypotheses: Starting Small and Starting Big. Starting Small states that limitations (small working memory capacity, simple structure, short string length, etc.) are beneficial for language learning, which explains why children are able to acquire language more easily than adults. Starting Big proposes the opposite, that input of chunks of language rather than individual units creates a stronger and more fluid understanding of grammatical relations between words. The current study aimed to investigate these theories in the context of an artificial language paradigm using a forced-choice task, a production task, a working …

The Influence Of Texting On Perceived Warmth: The Role Of Punctuation And Emoji, Elizabeth Mathews

Senior Honors Theses

Technology Mediated Communication (TMC) has become an essential part of interpersonal communication. Punctuation and emoji are major vessels of nonverbal communication in texting. The impact of punctuation and emoji use on perceptions of warmth was tested with 291 residential undergraduate students at Liberty University who were at least 18 years old. Through an online questionnaire, participants read a series of text messages with a randomly assigned condition of having either punctuation and emoji, punctuation and no emoji, no punctuation and emoji, or no punctuation and no emoji. Results indicated a significant main effect for the presence of emoji on perceived …

Re-Thinking L1-L2 Similarities And Differences In English Proficiency: Insights From The English Reading Online (Enro) Project., Noam Siegelman, Irina A. Sekerina, Victor Kuperman

Publications and Research

This article presents the ENglish Reading Online (ENRO) project that offers data on English reading and listening comprehension from 7,338 university-level advanced learners and native speakers of English representing 19 countries. The database also includes estimates of reading rate and seven component skills of English, including vocabulary, spelling, and grammar, as well as rich demographic and language background data. We first demonstrate high reliability for ENRO tests and their convergent validity with existing meta-analyses. We then provide a bird's-eye view of first (L1) and second (L2) language comparisons and examine the relative role of various predictors of reading and listening …

Prediction In Bilingual Sentence Processing: Is It Linked To Production?, Meir Natalia, Olga Parshina, Irina A. Sekerina

Publications and Research

The Unified Competition Model (MacWhinney, 2012) accounts for cross-linguistic differences in thematic role mapping. We investigated production and predictive use of accusative case morphology in Russian-Hebrew bilingual children. We also investigated the role of production in predictive processing testing the Prediction-by-Production Account (Pickering & Garrod, 2018) vs. the Missing Surface Inflection Hypothesis (Prévost & White, 2000). Three groups of children aged 4–8 participated: Russian-Hebrew-speaking bilinguals, Russian-speaking and Hebrew-speaking monolingual controls. All children participated in the accusative case production and Visual-World eye-tracking comprehension experiments. Bilinguals were tested in both of their languages. The results of the study confirmed the predictions of …
