Knowledge And Perceptions Of Slp Graduate Students Regarding Multiculturalism, Evy Jewell Hayes, Laura Amanda Mathews

Teaching and Learning in Communication Sciences & Disorders

Populations in the United States rise daily, as do the number of people who are considered multicultural. With this comes a greater need for speech-language pathologists (SLPs) who are able to assess and treat such individuals – a training process that begins in graduate programs. The primary objective of this study was to determine the knowledge and perceptions of graduate students in speech-language pathology as it pertains to multiculturalism. A survey was conducted to explore graduate students’ knowledge and perceptions of multicultural topics. Participants were recruited from programs in the southeastern United States via email. Just under 400 surveys were …

Trumpet Directivity From A Rotating Semicircular Array, Samuel D. Bellows, Joseph E. Avila, Timothy W. Leishman

Directivity

The directivity function of a played musical instrument describes the angular dependence of its acoustic radiation and diffraction about the instrument, musician, and musician’s chair. Directivity influences sound in rehearsal, performance, and recording environments and signals in audio systems. Because high-resolution, spherically comprehensive measurements of played musical instruments have been unavailable in the past, the authors have undertaken research to produce and share such data for studies of musical instruments, simulations of acoustical environments, optimizations of microphone placements, and other applications. The authors acquired the data from repeated chromatic scales produced by a trumpet played at mezzo-forte in an anechoic …

Recursive Functional Learning In Nonfluent Aphasia, Gerald C. Imaezue

Dissertations, Theses, and Capstone Projects

People with nonfluent aphasia (PWNA) require feedback from an external agent as well self-feedback to facilitate performance of language production tasks. The extent to which PWNA can use self-feedback alone to improve their task performance is unknown. In addition, it is argued that self-feedback may reinforce or minimize performance errors over time. To test whether either is the case, we introduce an original learning mechanism, recursive functional learning, which uses self-feedback loops to optimize recursively multiple subsystems (cognitive and linguistic subsystems) that PWNA engage during task performance. We used this mechanism to underpin a novel automated procedure we developed, recursive …

The Directional Effect Of Target Position On Spatial Selective Auditory Attention, Heesung Park

Dissertations, 2020-current

Spatial selective auditory attention plays a crucial role in listening in a mixture of competing speech sounds. Previous neuroimaging studies have reported alpha band neural activity modulated by auditory attention, along with the alpha lateralization corresponding to attentional focus. A greater cortical representation of the attended speech envelope compared to the ignored speech envelope was also found, a phenomenon known as 'neural speech tracking’. However, little is known about the neural activities when attentional focus is directed on speech sounds from behind the listener, even though understanding speech from behind is a common and essential aspect of daily life. The …

New Mexico Teachers’ Perceptions Of Students Who Stutter, Kyla Evelyn Cook

Speech and Hearing Sciences ETDs

Although stuttering may have a negative impact on quality of life, social support can mediate this impact and result in better outcomes. Teachers can be an important support for children. However, studies have shown that teachers have similar biases and knowledge compared to the public, and therefore may hold harmful beliefs about their students who stutter. This online survey is part of the assessment phase that aims to investigate the local attitudes and beliefs of K-12 school teachers in New Mexico. The data showed that New Mexico teachers have similar knowledge and biases as teachers globally. Results indicate New Mexico …

Non-Negative Matrix Factorization Improves The Efficiency Of Recording Frequency-Following Responses In Normal-Hearing Adults And Neonates., Fuh-Cherng Jeng, Tzu-Hao Lin, Breanna N Hart, Karen Montgomery-Reagan, Kalyn Mcdonald

Ambulatory and Primary Care Articles

OBJECTIVE: One challenge in extracting the scalp-recorded frequency-following response (FFR) is related to its inherently small amplitude, which means that the response cannot be identified with confidence when only a relatively small number of recording sweeps are included in the averaging procedure.

DESIGN: This study examined how the non-negative matrix factorisation (NMF) algorithm with a source separation constraint could be applied to improve the efficiency of FFR recordings. Conventional FFRs elicited by an English vowel/i/with a rising frequency contour were collected.

RESULTS: The improvements of FFR recordings, defined as the correlation coefficient and root-mean-square differences across a sweep series of …

Sound-Category Learning And Memory Skills In Neurotypical Adults And Adults With Language-Learning Disabilities, Allison Fulcher

University Honors Theses

This study evaluates the impact of memory skills (procedural, declarative, and working) and sound discrimination abilities, on the ability of adults with and without Language Learning Disability (LLD) to learn two sound-category structures, one designed to be learned implicitly and the other designed to be learned explicitly. This design tests a theorized etiology for LLD, the Procedural Deficit Hypothesis (PDH), which posits that LLD is caused by selective impairments to procedural memory and implicit learning. It also serves to evaluate factors and conditions that contribute to success in second-language learning for adults, who are less neurologically suited to the task …

Gender Diversity Cultural Responsiveness Education In Speech-Language Pathology Graduate Programs: A Pilot Survey, Tara E. Dickinson, Molly A. Normandin, Rachel W. Mulheren

Teaching and Learning in Communication Sciences & Disorders

Purpose: Gender-affirming voice therapy aims to align a person’s voice and communication with their gender identity. Historically, transgender and gender-nonconforming (TGNC) individuals have been marginalized and continue to face significant healthcare disparities. The goal of this research was to examine the self-perceived preparedness of recent speech-language pathology (SLP) graduates for working with TGNC clients. A survey was developed to include both multiple choice and open-ended questions. Topics included graduate-level training on working with TGNC individuals, perceived preparedness to work with this client population, educational resources sought by respondents, and suggested improvements for SLP graduate programs. Thirty recent (since 2016) …

Establishing Cueing Skills When Treating Bilingual Speech Sound Disorders, Carlos D. Irizarry-Pérez, Mirza J. Lugo-Neris, Andrea Martinez-Fisher

Teaching and Learning in Communication Sciences & Disorders

Purpose: This study sought to train cueing skills in first-year graduate students when working with bilingual children with speech sound disorders to ensure fidelity of intervention of a larger research investigation.

Method: Before explicitly training cueing skills, three students were randomly assigned bilingual clients that had been previously diagnosed with a speech sound disorder and asked to administer trial therapy. During the instructional phase, we gave students a cueing protocol, a scoring template, and feedback. We assessed performance according to challenge-point criteria and adherence to our cueing protocol.

Results: Performance varied per student, but overall scores were higher during the …

Caring For Individuals Who Are Experiencing Homelessness: An Audiologist’S Toolkit, Jenna Marie Sparacio

Dissertations, Theses, and Capstone Projects

National-level counts for individuals experiencing homelessness have been steadily on the rise. People experiencing homelessness face extraordinary barriers and challenges in accessing health care services, including hearing healthcare. Additionally, there is a high prevalence of self- reported hearing difficulties and hearing handicap among people experiencing homelessness. Hearing loss status and management is often not prioritized in healthcare settings, and treatment plans are not typically modified to best address the hearing needs of individuals who are homeless. This evidence-based toolbox for audiologists was developed to help understand and mediate healthcare barriers that people experiencing homelessness face, as well as to help …

Exploring The Potential Of Hearing Screening Smartphone Applications To Enhance Access To Hearing Healthcare: A Literature Review, Adam Sulaiman

Dissertations, Theses, and Capstone Projects

In 2016, the National Academies of Sciences (NAS) published a landmark consensus report with several recommendations to enhance the availability and affordability of hearing healthcare in the United States. Among the most notable of the recommendations was the creation of a new category of FDA-approved Over-the-Counter (OTC) hearing aids. Unlike the traditional hearing aid model, which requires a comprehensive hearing test by a hearing health professional prior to purchase, OTC hearing aids would be directly available for sale to any American adult with a self-perceived mild-to-moderate degree of hearing loss. This proposal has now become reality with the passage of …

Audiological Management Of Children With Down Syndrome: A Toolkit For Caregivers, Natalie Lisiewicz

Dissertations, Theses, and Capstone Projects

Children with Down syndrome may have multiple medical co-morbidities. This can result in an overwhelming number of medical appointments and information for caregivers to keep track of. Middle ear dysfunction, among other otologic abnormalities, is common in the Down syndrome population, and the presence of these conditions will result in referrals to an audiologist to monitor hearing sensitivity. While hearing may not be the most pressing concern as compared to a possible life-threatening condition such as a heart defect, it is still a crucial factor in a child’s overall development.

This toolkit is designed with the intention of educating caregivers …

Examining The Effect Of Training Using Natural And Noise-Vocoded Sentences On Noise-Vocoded Speech Perception In Normal-Hearing Listeners, Alexis Leiderman

Dissertations, Theses, and Capstone Projects

Auditory training has been shown to be an intervention strategy that may improve speech perception abilities in individuals with and without hearing loss. Within the cohort of individuals with hearing loss, auditory training has also been shown to have an improvement on speech perception in cochlear implant users. In several training studies, normal-hearing listeners have been exposed to noise-vocoded speech using auditory training paradigms to mimic how cochlear implant users may in turn be affected by these paradigms. These studies have highlighted certain areas for improvement in speech perception abilities based off of the training paradigms put in place. Several …

Examining The Effect Of Talker Familiarity Using Familiar And Unfamiliar Talkers On Noise-Vocoded Speech Perception In Normal-Hearing Listeners: A Training Study, Daria N. Collins

Dissertations, Theses, and Capstone Projects

Auditory training studies utilizing stimuli that are applicable to real-world processing of speech have been shown to improve speech perception abilities in normal hearing populations, those with hearing loss, and cochlear implant wearers. In particular, exposing normal hearing adults to noise-vocoded speech via auditory training studies has been shown to not only simulate the perceptual experience of a cochlear implant wearer, but have demonstrated promising improvements on speech perceptual abilities via the training paradigm. Additionally, studies have highlighted various variables that impact speech perception, including, talker familiarity. Talker familiarity has been shown to enhance speech perception both in listeners with …

Dynamic Assessment Of Aac Verb Symbols For Children With Autism Spectrum Disorder, Valerie Prieto, Cindy Gevarter, Cathy Binger, Mary Hartley

Speech and Hearing Sciences ETDs

This study used dynamic assessment (DA) with graduated prompting to evaluate whether preschool-aged children with autism spectrum disorder (ASD) demonstrated learning potential with verb-based augmentative alternative communication (AAC) symbols. Four participants completed DA sessions across three instructional conditions: (a) requesting actions embedded in play, (b) labeling actions embedded in play, and (c) labeling actions presented via video. Performance across these conditions along with a control condition was compared using an adapted multielement single-case design. Three participants demonstrated learning in at least two instructional conditions, and only one showed progress in the control condition. Overall, participants initially required less cueing to …

Verb Tense Production Differences Across Various Discourse Tasks In People With Fluent And Nonfluent Aphasia, Madeline Ann Zurbrugg

Honors Theses

Background: Fluent and nonfluent aphasia are both seen to exhibit varying degrees of morphosyntactic difficulties, with particular difficulties in verb tense production. There is disagreement regarding why tense is particularly impaired, which type of aphasia is more impaired and why, and whether some tense forms are more impaired than others. There is also evidence that language elicitation tasks affect language production measures because they require different linguistic and cognitive processes. This is likely also true for verb tense production. To date, no studies have examined discourse elicitation task effect on verb tense production in both fluent and nonfluent aphasia. The …

The Existence Of Stuttering-Like Disfluencies In American Sign Language, Katherine King

Honors Theses

For over a century, data have documented fluency disorders and stuttering-like disfluencies (SLDs) in multiple expressive modalities outside of speech, including musical expression, writing, and American Sign Language (ASL). The presence of SLDs in multiple expressive modalities presents the argument that SLDs are not limited to speech. This study specifically surveys fluent ASL signers relative to SLDs, analyzes SLD manifestations, and documents specific examples of stuttering behaviors in ASL.

This study analyzes SLD manifestations in ASL by conducting a survey developed from all known research within the SLD paradigm. Based on all previous research, SLD manifestations are categorized and represented …

Age-Related Decline In Neural Synchrony And The Ffr, Haley Szabo

Dissertations, 2020-current

It is a known phenomenon that speech understanding in background noise declines with advancing age. Although there is ample evidence of behavioral measures declining with age, there is less physiologic evidence. This study hypothesizes that the FFR will be degraded with advancing age, consistent with poorer phase locking. This is hypothesized to be present even in people with audiograms within normal limits. A second hypothesis is that middle-aged adults will have degraded neural representation as frequency increases, compared to a younger normal hearing group which will have better high frequency neural representation than the middle-aged group. Subjects were divided into …

Functional And Location Context Effects On Reading Sentences In Healthy Young Adults: Evidence From Eye Tracking Methods, Elizabeth Baird

Honors Theses

Spreading activation theory proves the way our brains are semantically wired to accept outside information and understand it. Previous studies have demonstrated the effects of spreading activation theory in different settings and activities. These effects are important to understand because they can be used in therapy and assessment for communication disorders. This study explores how the context of sentences affects reading time on noun targets in healthy young adults using an eye tracking method. Specifically, we compared functional and location context types and manipulated the context to be incongruent or congruent to the targets. Our research questions were (1) whether …

Multilingualism And Augmentative Alternative Communication: A Review Of The Literature, Hannah N. Lamarca, Natalie R. Andzik

Honors Capstones
