Department of Speech, Language, and Hearing Sciences Faculty Publications

Systemic hydration is known to promote optimal functioning of bodily systems—including the vocal folds. The impact of systemic dehydration on the biology of the vocal folds and the downstream effects of dehydration on voice output are not well understood. An in vivo rat model of systemic dehydration was employed to investigate vocal fold gene expression, histological changes, and acoustic changes in vocalization. Ultrasonic vocalizations (USVs) were recorded every day for 5 days (baseline), in male and female Long-Evans rats (N = 36, ages: 3–4 months) using an anticipatory reward paradigm. Next, rats were dehydrated (N = 18) using a published …

Deaf Community, Cochlear Implants, And Language Access, Amelia Segroves

Honors Theses

This thesis looks at how getting a cochlear implant can affect a Deaf or Hard-of-Hearing person’s identity, language development, and sense of belonging. It compares people who see deafness as part of a rich culture (big “D” Deaf) with those who see it more as a medical condition (little “d” deaf). By reviewing studies and articles, the research explores how early exposure to language, school environments, and family choices influence how people communicate and see themselves.

Aging-Related Hearing Decline And Resting State Networks, Cassidy S. T. Ellsworth

College of Education and Human Sciences: Dissertations, Theses, and Student Research

This study investigated the effects of age-related hearing decline on functional networks using resting-state functional magnetic resonance imaging (rs-fMRI). The main objective of the present study was to examine resting-state functional connectivity (rsFC) and graph theory-based network efficiency metrics in forty-nine adults categorized by age and hearing thresholds to identify the neural mechanisms of age-related hearing decline. RsFC within key brain networks and auditory-related brain regions, including the default mode network, salience network, dorsal attention network, and primary auditory cortices, was assessed using region-of-interest (ROI)-based and graph theory approaches. Functional metrics, such as rsFC strength and global and local efficiency, …

Music And Word Learning In Children Diagnosed With Developmental Language Disorder, Rebekah G. Sweeney

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Purpose: This study investigates whether incorporating music into vocabulary interventions improves rate of learning and retention of words in children with developmental language disorder (DLD). Emerging literature continues to show the plentiful benefits of music as a tool for intervention in many settings, including the world of speech pathology (Levitin, 2024). However, it is also evident that there is a connection between struggling with language, and struggling with musical elements, such as rhythm and pitch perception, particularly in children with DLD (Boorom et al., 2022; Kreidler et al., 2023). This study seeks to tease out if music is an effective …

The Stages Of Change Model As Applied To Cluttering: Next Steps, Kathleen Scaler Scott, Samantha Delmar, Sarah Hardy, Emma Schaedler, Erica Scheinberg, Kateri Grice, Brenna Field, Margaret Koester, Emma Maley, Kayla Montemarano, Brooke Price

Student Research Poster Presentations 2025

This study is based upon the Transtheoretical/Stages of Change model. The model has been studied in adults with a variety of health behaviors such as addiction (Prochaska, 1999; Prochaska &DiClemente, 1984) and has been applied to current stuttering treatment (Zebrowski et al., 2021) to assess readiness for change. The Stages of Change model consists of five stages: precontemplation, contemplation, preparation, action, and maintenance. Whenever considering making a change, as one would do as part of speech therapy, clients may move in and out of these stages. Therefore, it is important to understand what stage a client is in in order …

Experiences Of Those With "Other" Disfluencies, Kathleen Scaler Scott, Emma Schaedler, Erica Scheinberg, Sarah Hardy, Margaret Koester, Brenna Field, Emma Maley, Kayla Montemarano, Kateri Grice

Student Research Poster Presentations 2025

This ethnographic study collected and analyzed interviews of 8 children with “other” fluency disorders: cluttering, atypical disfluency, excessive non-stuttering like disfluency. Each school-age child participated in a semi-structured interview focusing on grand and mini tour questions. The participants were asked to speak about their perspective and experience with communication in general. Preliminary results of this study revealed the following themes: friendships are hard; high-level communication is a goal; everyone doesn’t ‘get’ me when I talk.

An Observational Study Of Discourse Tasks And Running Speech Sampling In The Assessment Of Paediatric Voice Quality, Victoria Reynolds, Kristin Scavo-Smith, Kate Oteng-Bediako, Sophie Scanlon

Speech-Language Pathology Faculty Publications

Introduction

Running speech sampling is an essential component of a paediatric voice evaluation, in that it should provide the examiner with a representative vocal sample of the child's everyday voice use outside of the clinic setting. Current speech sampling practices, consisting of reading tasks, informal conversation sampling and the voice question ('Tell me about your voice problem'), may not elicit consistent samples or samples of sufficient length to allow the examiner to make a reliable and valid judgement about vocal quality. The aim of this study is to compare the voice quality of children produced in response to existing running …

Revealing Spatiotemporal Neural Activation Patterns In Electrocorticography Recordings Of Human Speech Production By Mutual Information, Julio Kovacs, Dean Krusienski, Minu Maninder, Willy Wriggers

Mechanical & Aerospace Engineering Faculty Publications

Background

Spatiotemporal mapping of neural activity during continuous speech production has been traditionally approached using correlation coefficient (CC) analysis between cortical signals and speech recordings. A prior study employed this approach using electrocorticography (ECoG) data from participants who underwent invasive intracranial monitoring for epilepsy. However, CC cannot detect nonlinear relationships and is dominated by the correspondence between periods of silence and of non-silence.

New Method

We introduce the mutual information (MI) measure, which can capture both linear and nonlinear dependencies. We validated CC and MI on the sub-second spatiotemporal brain activity recorded during continuous speech tasks. To refine the results, …

Pediatric Hearing Loss: Screening For Developmental Delays Among Children With Hearing Aids, Kelsey Wallace

Entry-Level Occupational Therapy Doctorate - Doctoral Capstone Symposium

Children with hearing impairments are at risk for developmental delay, and research has shown that children born with sensorineural hearing loss (SNHL) are at a higher risk for delays in motor, sensory, and social skills development. The literature points to an obvious impact of hearing loss on development, but also a lack of screening for this phenomenon beyond language development skills. A doctoral capstone project was conducted to pilot a process for the implementation of developmental screening for children with hearing aids (HAs), as well as subsequent therapy referrals and parent education, in collaboration with a hospital-based pediatric audiology department. …

Practicing Clinicians' Views Of The Life Participation Approach To Aphasia Therapy, Stephanie H. Mays

Theses and Dissertations--Communication Sciences and Disorders

The Life Participation Approach to Aphasia therapy (LPAA) aligns with a person-centered, functional approach to speech therapy. Past research has demonstrated that persons with aphasia (PWA) benefit from this approach and prefer it when compared to the traditional medical model to therapy. However, a disconnect between PWA preferences and SLP treatment approaches in therapy persists. This study aims to identify both barriers and facilitators that SLPs face when implementing LPAA. Five CCC-SLPs practicing in the state of KY with experience working with PWA were recruited as participants. Participants were placed into two focus groups, with each group meeting for 2-3 …

Parkinson Disease (PD) is a neuro-progressive movement disorder that impacts all movement of the body, including speech production. Ninety percent of individuals living with PD will experience hypokinetic dysarthria, a motor speech disorder, during the progression of their disease. Clear speech instruction is a treatment strategy used to increase motor speech outcomes in those with PD. Studies have shown positive changes in articulation, prosody, voice, and listener perception measures in those with PD after clear speech instruction …

Exploring Physicians/Physician Assistants Perspectives On The Challenges And Communication Approaches When Communicating With People With Aphasia, Alexandra M. Rogers

SURF Posters 2025

Aphasia is an acquired language disorder that results from damage to the language areas of the brain, typically located within the left hemisphere. Individuals with aphasia often experience significant challenges while communicating with other individuals, including physicians and healthcare professionals. These barriers can ultimately lead to negative impacts on the quality of care, patient experiences, and overall health outcomes. The lack of consistent use of communication strategies as well as a general misunderstanding of aphasia by medical staff, further contributes to communication breakdowns. As a result, medical assessments can be misinterpreted, treatments may be delayed, and patients may feel less …

An Aphasia Friendly Questionnaire For Post-Stroke Fatigue, Abigail Best

Williams Honors College, Honors Research Projects

A stroke is when there is lack of blood flow to part of the brain. It can cause permanent damage, such as paralysis, sensory changes, difficulty with speech and language (such as aphasia), and decreased memory. Within this project, we will discuss individuals post-stroke who are diagnosed with aphasia, which is the inability to understand and express language. Currently, there are minimal resources available to help a healthcare worker define and assess the fatigue level of a patient post-stroke who is also diagnosed with aphasia. The first objective of this research is to discuss stroke and aphasia. The second objective …

Journal of Early Hearing Detection and Intervention

Evidence has indicated that Early Hearing Detection and Intervention (EHDI) programs have lowered the age of identifying permanent hearing loss (PHL) in childhood, a first step to intervention. However, limited research has compared the age of diagnosis before and after implementation in one jurisdiction across the full range of PHL.

Methods: Children diagnosed with PHL in Ottawa, Canada were identified from the Child Hearing Lab database at the Children’s Hospital of Eastern Ontario and linked to Ontario health administrative data. Age of identification of PHL of children born in the pre-infant hearing program (IHP) era (1991-2002) was compared to those …
