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 …

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 …

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 …

Spanish Conquistadors As God’S Chosen People: The Role Of Biblical Metaphor In Angélico Chávez's Recounting Of Southwest History, Nicholas L. Chavez

International Journal of the Linguistic Association of the Southwest

This study presents a critical discourse analysis of Fray Angélico Chávez’s My Penitente Land: Reflections on Spanish New Mexico through a cognitive linguistic lens based on Hawkins’s notion of iconographic reference. A metaphor analysis first identifies Chávez’s framing of New Mexican history as biblical narrative, mapping Old Testament stories, locations, and characters onto Spanish colonial events. The iconographic reference analysis then demonstrates how this metaphor functions discursively: a biblical iconographic frame of reference allows Chávez to create a biblically-based heirarchy which maps onto Spanish–Indigenous relations, positioning Spaniards as a chosen people and implicitly justifying colonial atrocities by aligning Indigenous groups …

Comparative Semiotic Analysis Of Non-Verbal Communication: Apis Mellifera Waggle Dance And Human Kinesic Signaling Systems, Nishtha Tikalal

Honors Undergraduate Theses

There are many parallels between two seemingly disparate forms of non-verbal communication: the waggle dance of Apis mellifera (honeybees) and human kinesic signaling systems. Through a comparative semiotic analysis, this research aims to conduct a comparative semiotic analysis, investigating structural and functional similarities between these communication methods, challenging anthropocentric assumptions about meaning making in the natural world. This research employs a meta-synthesis approach, drawn from a methodological literature review to examine historical representations of bee-human relationships, semiotics of non-verbal communication, and the specific mechanisms of the waggle dance and human kinesics. This methodology involves systematic categorization and analysis of extracted …

On The Benefits Of Directness In Virtual Characters For Motivational Interviews, Michael O'Mahony, Cathy Ennis, Robert Ross

Conference papers

Understanding the factors influencing successful engagement with Embodied Conversational Agents (ECAs) remains a significant challenge. This understanding could be used to personalise agents to users to improve interactions. Some studies have shown that simulating personalities in healthcare agents can improve effectiveness and engagement. However, it is not yet well understood how variations of agent personality can be leveraged to improve user engagement with Motivational Interviewing (MI) ECAs. Specifically how the balance between agent warmth and directness can be controlled in an MI agent to improve likeability and engagement. We conducted an online Wizard-of-Oz (WoZ) mediated study of two variants of …

Exploring The Efficacy Of Transcutaneous Auricular Vagal Nerve Stimulation On Post-Stroke Aphasia: A Single-Subject Design Study, Aswathy Anakkathil Pradeep

LSU Doctoral Dissertations

Background: Anomia or word-retrieval difficulty is a common long-term language impairment for individuals with post-stroke aphasia. Several behavioral interventions like semantic feature analysis (SFA) have shown positive results in naming outcomes, but continue to face difficulty in generalizing the treatment effects to untreated items. With recent advancements in technology, researchers are developing newer neuromodulation devices that aim at promoting neuroplasticity and neural reorganization in post-stroke individuals. Transcutaneous auricular vagal nerve stimulation (taVNS) is a relatively new technology that aims at stimulating the auricular branch of the vagal nerve to promote neuroplasticity. Studies have shown taVNS to potentially facilitate positive improvements …

Getting To The Point: Contrasting Directness And Warmth In Motivational Embodied Conversational Agents, Michael O'Mahony, Cathy Ennis, Robert Ross

Conference papers

Enhancing long-term engagement with conversational agents remains a significant challenge. Controlling the perceived warmth or directness of an agent’s personality through the style of its generated text could be used to increase user likeability. This paper reports an investigation of a Wizard-of-Oz (WoZ) mediated study of two variants of a motivational embodied conversational agent to measure user perception of and attitudes towards warmth in interaction style. Results show a significant effect of users preferring an agent with a "more direct" personality for this scenario, though this effect is in many ways nuanced.

Promoting Emergent Literacy In Preschool Through Extended Discourse: Covert Translanguaging In A Mandarin Immersion Environment, Robin E. Harvey, Kevin M. Wong

Education Division Scholarship

Rich oral language practices, including the opportunity and ability to participate in cognitively and linguistically challenging extended discourse, are foundational to early literacy development. To meet children’s needs in their first exposure to the languages of schooling, educators may engage students in extended discourse multilingually. The current study focuses on student-centered translanguaging conversations to examine strategies that preschool teachers employ to support young children’s emerging bilingual and biliteracy development in a Mandarin immersion preschool serving primarily nonheritage learners of Mandarin in the United States. Findings indicate that, despite the school’s Mandarin-only policy, teachers engaged in covert translanguaging practices to extend …

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 …

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 …

Auditory Free Classification Of Gender Diverse Speakers, Brandon Merritt, Tessa Bent, Rowan Kilgore, Cameron Eads

Departmental Papers (Speech)

Auditory attribution of speaker gender has historically been assumed to operate within a binary framework. The prevalence of gender diversity and its associated sociophonetic variability motivates an examination of how listeners perceptually represent these diverse voices. Utterances from 30 transgender (1 agender individual, 15 non-binary individuals, 7 transgender men, and 7 transgender women) and 30 cisgender (15 men and 15 women) speakers were used in an auditory free classification paradigm, in which cisgender listeners classified the speakers on perceived general similarity and gender identity. Multidimensional scaling of listeners’ classifications revealed twodimensional solutions as the best fit for general similarity classifications. …

Exploring Cross-Linguistic Speech Perception In Hindi, English, And Romance-Language Through Temporal Dynamics Of Neural Activity, Yuga Kothari

Dissertations, Theses, and Capstone Projects

This study examines the effect of linguistic experience on the neural processing of Voice Onset Time (VOT) in Hindi and Romance language (Spanish and Portuguese) individuals who are bilingual in English and monolingual English speakers using the event-related potential (ERP) Mismatch Negativity (MMN) response. VOT is a linguistic property that measures the time elapsed between the release of a stop consonant and the beginning of voicing, that is, vocal fold vibration of a following vowel. In a double-oddball paradigm, participants’ (n = 41) ERP were recorded while listening to speech sounds differing in VOT. The bilabial short lag stop [p] …

Unveiling Spanish Language Attitudes In A Los Angeles School And A Third-Generation Multigenerational Mexican-American Family, Eric Alvarez

International Journal of the Linguistic Association of the Southwest

This chapter unearths some of the diverse attitudes towards Spanish of a third-generation child in Los Angeles (L.A.), California, her family members, and school personnel. L.A. is a tension-ridden contact zone (Pratt, 1991) where Spanish has traditionally been subjugated and is still a lesser-taught language (LTL) despite decades of research showing that bilingual education positively impacts student attitudes (Potowski & Muñoz-Basols, 2020). Lack of continuity (Caloi & Torregrossa, 2021) in formal instruction and inconsistent heritage Spanish use in the home may entail divergent attitudes towards Spanish, possibly hindering multigenerational transmission. Decades-long turbulent California language policies (CLP) (Macias, 2001) have consistently …

Reporting On Un Security Council: Decoding Media Bias, Alessandra Loiero

Dissertations and Theses

This thesis explores Western media's representation of the United Nations (UN), focusing on the Security Council's role in global conflict resolution. It examines how UN-accredited correspondents perceive the effectiveness of the Security Council, particularly when the body faces deadlock. The study employs text analysis techniques to identify biases and perceptions in media coverage, using The New York Times' reporting on the Ukraine conflict as a case study. It illuminates framing effects in journalistic narratives, revealing how journalists subtly interject their views when reporting, often revealing unrealistic expectations and shedding light on the limitations of the UN's mandate or its inability …

The Influence Of Visual Perspective On The Cognitive Effort Required For Mental Representation, Jeffrey P. Hong

Theses and Dissertations (Comprehensive)

Mental representation is the process by which an individual simulates an event in their mind’s eye. This process is the foundation of the ability to remember the past, engage in prospective thinking, or imagine fictitious scenarios. An individual can mentally represent any event through their own eyes—the first-person perspective or from the viewpoint of an external observer—the third-person perspective. The perspective of representation influences outcomes related to memory, visuospatial processing, affect, social cognition, clinical diagnoses, and language processing. In turn, an individual’s tendency to favour either perspective is shaped by related factors.

The current research consists of four experiments, designed …

Destigmatizing Working With Dyslexic Learners, Riley N. Dandurand

The Writing Center Journal

In the field of writing center research there is a paucity of information regarding tutoring students with dyslexia. This comes as no surprise considering it is only in the last 50 years that there has been a conscious effort to include those who have exceptionalities in all areas of education. In addition to a lack of research and training there is another issue that arises with disclosing exceptionalities. Those studying dyslexia have found that students are hesitant to disclose their learning disability because of the stigma and feelings of differentiation from their peers (Brizee et al., 2012). The question then …

Conceptual Meaning In Phonology: Multimodal Iconic Expressions In Discourse Focus, David Páez Acevedo

Linguistics ETDs

In everyday communication, speakers go beyond words to synchronize speech sounds and gestures, adding nuanced meanings. For instance, in Colombian Spanish, recounting the distant past involves elongating words, modulating pitch, and using expressive hand movements. This dissertation explores this phenomenon, termed Multimodal Iconic Expressions (MMIEs), using Cognitive Linguistics and Cognitive Grammar. The quantitative study uncovers correlations between verb aspect, nominal quantification, and speech duration, revealing phono-iconic connections. The qualitative study examines construal operations giving rise to MMIEs across semantic domains. MMIEs predominantly appear in discourse Focus, with durative events and mass-like quantities exhibiting pronounced phono-iconic associations. Patterns include stress and …

Association Strength Between Concepts As The Origin Of The "Foreign Language Effect", Emilia Ezrina

Dissertations, Theses, and Capstone Projects

Bilinguals sometimes make decisions in verbal tasks differently in their first (L1) and second (L2) language. This phenomenon is known as the foreign language effect (FLE), and it suggests strong connections between language and cognition. On the one hand, it is possible that L2 “blunts” emotional language. However, the FLE can be observed in non-emotional tasks. Therefore, it is possible that L2 requires more deliberate processing due to increased cognitive load, leading to more rational decisions. The support for each explanation is mixed.

In this thesis we propose looking for a single explanation for all instances of the FLE. After …

The Effect Of Word Predictability On Proofreading Accuracy And Reading Time, Sam Prasad

Theses and Dissertations

Proofreading, or reading with the purpose of finding and correcting errors, has been used in psycholinguistic research to study the relationship between bottom-up and top-down cognitive processes. The current study examined the effects of word predictability on reading time using a word-by-word self-paced reading (SPR) task. A sample of 102 native English speakers read sentences containing letter transposition errors in predictable and unpredictable contexts. Half of the sentences were followed by a question asking if there was an error in the sentence they had just read. Participants’ accuracy in detecting the errors and the time they spent reading the error-bearing …

Genetic Implications Of Language Acquisition, Marissa Renee Ciccarini

Honors Scholar Theses

The argument about whether language acquisition is "nature" or "nurture" has been long debated. Linguists have concluded that it requires the two, but how much does language acquisition rely on nature? Children show the capacity to learn languages quickly and without much effort. While research suggests that infants absorb many visual and verbal cues in their environment, biological structures are the underlying component of how this knowledge is gathered and organized. The genetics that code for specific neurophysiological pathways affect how people interact with their environment and where information is stored, forming the basis for these biological structures. Genetic research …

The Influence Of Native Language And Sentence Form On Memory Of Motion Events, Stephanie L. Lopez

LSU Master's Theses

This study utilized four experiments to investigate the extent to which native language influences memory in accordance with linguistic relativity. In Experiment 1, monolingual English speakers and Spanish/English bilinguals were divided into a verbal encoding condition and a verbal suppression encoding condition and watched motion events of low or high physical salience. Participants engaged in a recognition memory task followed by an event memory similarity judgment task. In Experiment 2, native monolingual English speakers were divided into an English-like (or manner-on-verb) description group, a Spanish-like (or path-on-verb) description group, mimicking the language groups of Experiment 1 respectively, and a verbal …

Bypass Language En Route To Meaning At Your Peril, Lindsay N. Harris, Charles A. Perfetti, Elizabeth Hirshorn

CISLL Publications

The learning account of the puzzle of ideography cannot be dismissed as readily as Morin maintains, and is compatible with the standardization account. The reading difficulties of deaf and dyslexic individuals, who cannot easily form connections between written letter strings and spoken words, suggest limits to our ability to bypass speech and reliably access meaning directly from graphic symbols.

The Contribution Of Phonological Overlap To The Cognate Effect: An Event-Related Potential Study Of Persian-English Bilinguals, Zahra Fotovatnia

Theses and Dissertations (Comprehensive)

The purpose of this dissertation was to examine the contribution of phonological overlap to visual word recognition. More specifically, this study aimed at testing the phonological account of the cognate effect (i.e., faster and more accurate mental processing of cognates than noncognates) in visual word recognition in Persian and English, which are languages with different scripts. The phonological account attributes the cognate effect to the phonological similarity of cognates (form and semantically related words) in addition to the conceptual similarity that cognates and noncognates (semantically related words) have and to the degree of phonological similarity between cognates in two languages. …

Multilingualism And Memory: Investigating Possible Differences In The Abilities Of Monolingual And Multilingual College Students, Clara E. Barned

Honors Projects

This study investigated whether there is a difference in the memories of monolingual and multilingual undergraduate students using simple memorization tasks. There were 46 participants, 30 of which were monolingual (only knew one language) and 16 of which were multilingual (knew two or more languages). There was found to be no significant difference between the performance of the two groups, with the data generating a p-value of 0.557. This study further suggests related avenues of research and ways in which the study could be improved in the future.

Retrieval Practice Promotes Learning Of Turkish As A Foreign Language: A Computer-Assisted Language Learning Study, Maya C. Rose

Dissertations, Theses, and Capstone Projects

Adults generally find it difficult to learn a new language, yet exhibit remarkable individual differences in outcomes. Variation in second language (L2) learning is associated with input conditions (Morgan-Short et al., 2010) as well as learners’ aptitude (Dörnyei, 2005). Recent work has demonstrated benefits of retrieval practice in promoting L2 learning of grammatical patterns and vocabulary in both artificial and natural languages (Hopman & MacDonald, 2018; Keppenne et al., 2021). With that said, when retrieval practice is based on oral recall as opposed to a recognition test, it confounds potential benefits of repeated testing (Rowland, 2014) with those associated with …

Dialogue Policies For Confusion Mitigation In Situated Hri, Na Li, Robert J. Ross

Articles

Confusion is a mental state triggered by cognitive disequilibrium that can occur in many types of task-oriented interaction, including Human-Robot Interaction (HRI). People may become confused while interacting with robots due to communicative or even task-centred challenges. To build a smooth and engaging HRI, it is insufficient for an agent to simply detect confusion; instead, the system should aim to mitigate the situation. In light of this, in this paper, we present our approach to a linguistic design of dialogue policies to build a dialogue framework to alleviate interlocutor confusion. We also outline our sketch and discuss challenges with respect …

Legislative Language For Success, Sanjana Gundala

Master's Theses

Legislative committee meetings are an integral part of the lawmaking process for local and state bills. The testimony presented during these meetings is a large factor in the outcome of the proposed bill. This research uses Natural Language Processing and Machine Learning techniques to analyze testimonies from California Legislative committee meetings from 2015-2016 in order to identify what aspects of a testimony makes it successful. A testimony is considered successful if the alignment of the testimony matches the bill outcome (alignment is "For" and the bill passes or alignment is "Against" and the bill fails). The process of finding what …
