Exploring Tonal Focus: Qualitative Perspectives And Acoustic Correlates In Slps And Singers, Lily C. Carpenter

Theses and Dissertations--Communication Sciences and Disorders

Tonal focus is a complex construct that has variable definitions and interpretations across professions and within existing literature. Although tonal focus is widely described both clinically and pedagogically, both fields differ in their perspectives and goals related to the concept. This study aims to understand singers’ and speech language pathologists’ (SLP) conceptual perception and acoustic demonstration of tonal focus. Eleven SLPs and six singers were recruited to participate in the study. Participants completed an interview with the primary investigator and were recorded producing forward, neutral, and backward tonal focus in various contexts. Acoustic and qualitative analysis indicated that tonal focus …

Exploring The Impact Of Age On Traumatic Brain Injury Cause And Recovery In Arkansas: A Retrospective Review, Abby Jones, Steven Wheeler, Jessica Danley

2026 Honors Symposium

Traumatic brain injuries (TBIs) remain a major public health concern, and increasing evidence goes to show the significance of the effect of age in quality of care, diagnosis, and recovery outcomes. In rural states, such as Arkansas, where research has shown a lack of resources and higher fatality rates among TBI patients, healthcare professionals can become better informed and equipped as a result of research efforts to uncover the effects of age on cause and recovery for inpatient TBI individuals in the early stages (Daugherty et al., 2022). Current research and prior evidence suggests that older individuals are more likely …

Department of Communication Sciences and Disorders Faculty Scholarship and Creative Works

Purpose

Research on barriers to augmentative and alternative communication (AAC) implementation in schools has focused primarily on individual clinician factors rather than district infrastructure. This clinical focus article examined how the presence or absence of a dedicated assistive technology (AT) specialist was associated with differences in AAC implementation and the use of AAC as a Tier 1 support.

Method

Eighteen educators, including AT specialists, SLPs, and a special educator, from 17 U.S. school districts participated in a 75-minute structured Zoom focus group. They rated 11 statements about district AAC practices using a 4-point Likert scale and discussed their responses in …

When Speech Speaks Louder Than Truth: Language Variation And Credibility In The Courtroom, Melanie E. Spinnie

Graduate Theses/Dissertations

This study aims to investigate how linguistic variation affects perceptions of credibility in courtroom settings. It focuses on how jurors, judges, and other individuals in the legal system may exhibit bias (consciously or unconsciously) based on how a defendant or witness speaks-- this could include speech disorders as well as differences in dialect, accent, and speech style. Through review of relevant literature, review of a relevant historical case, conducting a survey, and conducting a semi-structured interview, this study explores whether certain speech patterns or characteristics are disproportionately associated with negative judgments during legal proceedings, such as reduced credibility and trustworthiness. …

Brainstem Encoding Of Speech In The Extended High Frequencies And Its Behavioral Correlates, Sajana Aryal, Fan-Yin Cheng, Srikanta K. Mishra, Spencer Smith

Department of Communication Sciences and Disorders Faculty Scholarship and Creative Works

Whether the auditory nervous system can extract and use speech information carried in the extended high-frequency (EHF; >8 kHz) range is an unresolved question in auditory neuroscience. Although EHF sensitivity is increasingly recognized as important for speech perception, it is unclear whether EHF hearing is directly or indirectly involved in real-world listening. This study examined brainstem neural encoding of EHF speech components and the relationship between EHF hearing sensitivity and both neural and perceptual speech processing. Envelope following responses (EFRs) to broadband and high-pass filtered (>4 kHz and >8 kHz) speech stimuli, along with digits-in-noise speech recognition thresholds under …

Belting In Musical Theatre: Vocal Pathologies, Injuries, And Pedagogical Implications, Kaylee Piatt

Theses and Dissertations--Music

Belting has become one of the most defining and contested vocal styles in contemporary musical theatre. Valued for its dramatic immediacy, speech-like intensity, and ability to cut through amplified orchestration, belting is frequently associated with heightened injury risk and pedagogical controversy. This thesis examines the relationship between belting, vocal pathology, and pedagogy through an interdisciplinary lens that integrates voice science, clinical literature, and professional performance practice. Rather than framing belting as an inherently harmful or stylistically aberrant technique, this study conceptualizes belting as a functional vocal coordination shaped by physiological mechanisms, cumulative vocal load, and occupational demands.

Integrating Perspectives Of People With Aphasia: A Holistic Approach To Community Aphasia Groups Within An Intensive Comprehensive Aphasia Program, Mckinlee A. Mihelish

Graduate Student Theses, Dissertations, & Professional Papers

Introduction: People with aphasia (PWA) experience chronic communication deficits that impact daily life. Community Aphasia Groups (CAGs) are commonly used to address these challenges and have demonstrated psychosocial and communicative benefits; however, they lack standardized structure and are implemented with variability across settings. Additionally, much of the existing research focuses on group-level outcomes rather than participant-driven priorities, limiting clinicians’ ability to tailor interventions. This study examined what PWA want from CAG participation and how these priorities may change over time.

Methods: This quantitative study investigated priority changes among PWA participating in a CAG within a summer 2025 Intensive Comprehensive Aphasia …

Initial Qualitative Inquiry Into Social Proverb Use And Acceptability, Emma K. Hinds

Graduate Student Theses, Dissertations, & Professional Papers

Currently,  1 in 36 individuals are diagnosed with autism spectrum disorder (ASD), which is characterized by social communication differences and restricted and/or repetitive behaviors. Many children with ASD also present with sensory, behavioral, and emotional differences, underscoring the need for specialized, evidence-based interventions. Social proverb is a novel intervention approach developed by Dr. Schoffer Closson that provides in-the-moment guidance by explicitly stating expected social behaviors and the rationale behind them (e.g., “We cover our coughs, so we don’t spread germs”). To date, no research has examined the use of social proverbs as an intervention strategy. The purpose of this qualitative …

Beyond Mean Length Of Utterance: Novel Measures For Characterizing The Spoken Language Of Autistic Children, Janine Mathee-Scott, Courtney E. Venker

Speech Pathology and Audiology Faculty Research and Publications

Purpose:

Mean length of utterance (MLU) is a common measure of expressive language complexity in young children, including autistic children. However, means, by nature, obscure some information about spread and variability in data. Thus, we aimed to examine a new approach to characterizing linguistic complexity in autistic children by investigating the validity of two novel measures—range of length of utterance (RLU), standard deviation of length of utterance (SDLU)—alongside established measures: MLU and total utterances (TU).

Method:

Participants were 40 autistic children (12 girls, 28 boys; M_age = 41.78 months). Children participated in 10-min, play-based language samples with their caregivers. …

Selected Full-Text Master Theses 2021-

Purpose: Adolescents are at greater risk for traumatic brain injury (TBI), and TBI-related symptoms may contribute to disciplinary actions that increase their risk of entering the school-toconfinement pipeline. Given the disproportionate representation of racially marginalized male adolescents within this pipeline, this critically appraised topic (CAT) examined how race, gender, and socioeconomic status may influence school-based speech-language pathology (SLP) services and clinical decision-making following TBI. Method: A structured search of five electronic databases was conducted to identify studies examining speech-language pathologists’ (SLPs’) clinical decision-making and management of adolescents with TBI in relation to race, gender, and socioeconomic status. Relevant studies were …

Integrating Hippotherapy Into Interprofessional Aphasia Rehabilitation: A Feasibility Pilot Study, Bethany H. Wenger

Graduate Student Theses, Dissertations, & Professional Papers

Background and Significance: Stroke remains a leading cause of disability in the United States, affecting over 2.5 million individuals annually. Stroke-related motor and communication deficits often co-occur, increasing challenges for recovery, increasing social isolation, depression, and dependency. Hippotherapy has emerged as a novel treatment approach for neurorehabilitation; however, its application within interprofessional models for individuals with stroke-related motor and communication impairments remains underexplored. This study examines the feasibility, fidelity, and acceptability of an interprofessional intervention using hippotherapy for adults with chronic post-stroke aphasia, the purpose of which is to generate methodological guidance for future controlled trials.

Methods: A non-randomized, single-group …

Advancing Interprofessional Communication: Preliminary Outcomes Of A Novel Collaboration Framework In A Student Head Injury Clinic, Natalia Noce, Kelly Ann Pena, Susan Paparella, Andrew Lynch, Erin Keller, Aaron Dallman, Pamela Rothpletz-Puglia

Journal of Occupational Therapy Education

When healthcare providers practice interprofessional practice, care improves, and medical errors are reduced. Interprofessional Education Collaborative (IPEC) principles and the Team Strategies and Tools to Enhance Patient Performance and Safety (TeamSTEPPS®) frameworks are utilized in healthcare education to develop interprofessional collaborative practice skills, but there is little understanding of how these skills change over time. We sought to evaluate the development of interprofessional collaborative practice skills by examining graduate occupational therapy, physical therapy, and speech-language pathology students' first-hand reports of their experiences over time in an interprofessional head injury clinic. We employed an applied interpretive qualitative research approach longitudinally collecting …

The Qualitative Investigation Of The Role Of Nicu-Based Slps, Netanya Tsang

Selected Full-Text Master Theses Collection 2018-

In 2004 that the American Speech Language Hearing Association (ASHA) released a position statement pertaining the roles of SLPs in swallowing and feeding disorders, specifically in the Neonatal Intensive Care Unit (NICU). In the NICU, one of the last criteria for discharge of the neonate is to demonstrate consistent and stable feeding. For NICU-based speech-language pathologists (SLP)s, a primary responsibility is treating the neonate’s ability to feed and swallow. Within this specialized setting over time, the role of the SLP has changed, but there is significant variation across locations and setting; with little formally documented regarding updated responsibilities. Therefore, this …

Perspectives Of Poetry: Peering Into Poetry And Aphasia, Kristian M. Perez

Graduate Studies Theses and Dissertations 2026

People with aphasia often experience significant barriers to communication, emotional expression, and participation in meaningful life activities following stroke or neurological injury. Although poetry and creative expression have been explored in broader therapeutic contexts, limited research has examined how people with aphasia perceive poetry. The purpose of this qualitative study was to explore the perspectives of people with aphasia regarding definitions of poetry, level of interest in poetry and the factors influencing said interest. Semi-structured interviews were conducted with adults with aphasia recruited through convenience sampling. Participants responded to questions before and after exposure to the poem Trust by Mark …

Department of Communication Sciences and Disorders Faculty Scholarship and Creative Works

Traumatic brain injury (TBI) damages pathways throughout the brain and is a significant global health concern, particularly in low- and middle-income countries, where the incidence is high and long-term deficits are prevalent. This study explores the utility of central auditory processing (CAP) testing as a marker of previous TBI. Seventy individuals with a history of moderate to severe TBI (msTBI) were matched by age and sex to 46 healthy controls in Dar es Salaam, Tanzania. Participants underwent comprehensive behavioral CAP testing, including tests of speech-in-noise ability, temporal resolution, and dichotic listening. Multivariate logistic regression showed the Triple Digit Test (TDT) …

Prosodic Comparisons Between Speech And Music For Different Emotions, Reagan Brothers

Honors Projects

This study compares the prosodic acoustic characteristics between different emotional expressions in speech and clarinet playing and evaluates the similarities in prosody between these two domains. The prosodic features analyzed include pitch, loudness, and duration, which are the psychoacoustic terms referring to fundamental frequency [f_o], intensity, and rate of time. The American folksong “I’ve Been Working on the Railroad” was both spoken and performed with three emotions: neutral, sad, and happy. The first comparison was how each prosodic characteristic compared across the three different emotions within each domain, and then prosody was compared across the two domains …

Effect Of Digital Noise Reduction Processing On Subcortical Speech Encoding And Relationship To Behavioral Outcomes, Subong Kim, Mary Schroeder, Hari M. Bharadwaj

Department of Communication Sciences and Disorders Faculty Scholarship and Creative Works

Perceptual benefits from digital noise reduction (NR) vary among individuals with different noise tolerance and sensitivity to distortions introduced in NR-processed speech; however, the physiological bases of the variance are understudied. Here, we developed objective measures of speech encoding in the ascending pathway as candidate measures of individual noise tolerance and sensitivity to NR-processed speech using the brainstem responses to speech syllable /da/. The speech-evoked brainstem response was found to be sensitive to the addition of noise and NR processing. The NR effects on the consonant and vowel portion of the responses were robustly quantified using response-to-response correlation metrics and …

Protocol For Visual-Acoustic Intervention With Service Delivery In-Person And Via Telepractice (Visit) Non-Inferiority Trial For Residual Speech Sound Disorder, Tara Mcallister, Jonathan L. Preston, Elaine R. Hitchcock, Nina R. Benway, Jennifer Hill

Department of Communication Sciences and Disorders Faculty Scholarship and Creative Works

Background: Residual speech sound disorder (RSSD) is a high-prevalence condition that negatively impacts social and academic participation. Telepractice service delivery has the potential to expand access to technology-enhanced intervention methods that can help remediate RSSD, but it is not known whether remote service delivery is associated with a reduction in the efficacy of these methods. This project will systematically measure the outcomes of visual-acoustic biofeedback intervention when delivered in-person or online. Methods/design: This project, Visual-acoustic Intervention with Service delivery In-person and via Telepractice (VISIT), aims to treat 76 children in a parallel randomized controlled clinical trial in which children with …

Dual-Task Interaction Between Vestibular Function And Cognitive Processing Using The P300 Event-Related Potential, Laurel Elise Money-Nolan

Graduate Theses and Dissertations (2019 - present)

Previous research has established links between vestibular function and cognitive processing, aging and cognitive function, and aging and vestibular function. Theories of cognitive resource allocation discuss how cognitive resources, such as attention, are devoted towards and divided between tasks when multitasking. This dual-task study, utilizing a balance task and a listening/cognitive task, across the young- and middle-aged adult age range, aimed to evaluate potential relationships between vestibular function, cognition, and age, and to examine how cognitive resources might be allocated under dual-task conditions.

The dual-task protocol in this study utilized an oddball paradigm with tonal stimuli to measure the P300 …

Exploring Future Educators’ Roles In Classroom Aac Use: Insight Into Knowledge, Skills, And Attitudes, Katrina M. King

Honors College Theses

The United States public school system requires the provision of a free and appropriate public education (FAPE) in the least restrictive environment (LRE) for qualifying students with disabilities (U.S. Department of Education, n.d.). Speech, language, and hearing related disabilities are among the qualifying categories (U.S. Department of Education, n.d.). Students with these disabilities may have complex communication needs (CCN), or significant limitations in their speech, language, and communication abilities (Communication Rights Australia, 2018). Augmentative and alternative communication (AAC), a type of assistive technology, offers support for these students, however, several barriers inhibit full communicative participation (American Speech-Language-Hearing Association [ASHA], n.d.-a). …

The Radical Middle: Caregiver Beliefs About Language Access For Deaf And Hard Of Hearing Children, Monica Zmudzinski, Krystal L. Werfel

Journal of Early Hearing Detection and Intervention

The purpose of this study was to explore the communication choices of caregivers of deaf or hard of hearing (DHH) children. Specifically, we explored what communication options caregivers were presented with, identify what factors impacted a caregiver’s decision to pursue spoken language, and identify what barriers exist to learning sign language. We conducted semi-structured interviews with 20 caregivers of DHH children who had decision making power at the time of their child’s diagnosis. Transcripts were coded using an inductive approach with triangulation between authors. Many families reported that minimal to no information was provided about communication options at the time …
