Can The Use Of Art And Active Learning Improve Retention And Observational Skill Confidence Among Audiology Graduate Students, Aurora Weaver, Ashlyn Wheat, Travis Riffle, Chelsea Powell, Lindsey Leonard, Ryleigh Prickett, Anna Hill, Larry Molt

Teaching and Learning in Communication Sciences & Disorders

Human anatomy and physiology is considered one of the most difficult courses a student can take in a pre-health professional major in the US (Slominski, et. al., 2017). Research has revealed benefits of the use of art and anatomy within medical education, including improved clinical observational skills, greater understanding of disease and patient perspectives, and greater ability to empathize (Bell & Evans, 2014). Bell and Evans (2014) argue that observational skills are often overlooked in medical education. Use of art assignments in a graduate anatomy and physiology course will be discussed with reference to design and learning outcomes. The purpose …

Exploring Strategies For Modeling Sign Language Phonology, Lee Kezar, Riley Carlin, Tejas Srinivasan, Zed Sehyr, Naomi Caselli, Jesse Thomason

Communication Sciences and Disorders Faculty Articles and Research

Like speech, signs are composed of discrete, recombinable features called phonemes. Prior work shows that models which can recognize phonemes are better at sign recognition, motivating deeper exploration into strategies for modeling sign language phonemes. In this work, we learn graph convolution networks to recognize the sixteen phoneme “types” found in ASL-LEX 2.0. Specifically, we explore how learning strategies like multi-task and curriculum learning can leverage mutually useful information between phoneme types to facilitate better modeling of sign language phonemes. Results on the Sem-Lex Benchmark show that curriculum learning yields an average accuracy of 87% across all phoneme types, outperforming …

Impact Of Training And Experience On Hearing Loss Health Literacy In Speech-Language Pathologists, Ellen Claire Cooper

Theses and Dissertations

The purpose of this study was to explore general health literacy, hearing loss health literacy, and confidence levels among SLPs with different levels of academic training and on-the-job experience related to hearing loss and to understand how SLPs felt their training and experience contributed to their hearing loss health literacy development. Across two aims, we evaluated predictors of SLPs’ hearing loss health literacy and SLP beliefs of how hearing loss health literacy is gained. The results from this study indicated that SLPs had high levels of general health literacy and but marginal to low levels of hearing loss health literacy. …

Objective Discrimination Of Bimodal Speech Using Frequency Following Responses, Can Xu, Fan-Yin Cheng, Sarah Medina, Erica Eng, René Gifford, Spencer Smith

Department of Communication Sciences and Disorders Faculty Scholarship and Creative Works

Bimodal hearing, in which a contralateral hearing aid is combined with a cochlear implant (CI), provides greater speech recognition benefits than using a CI alone. Factors predicting individual bimodal patient success are not fully understood. Previous studies have shown that bimodal benefits may be driven by a patient's ability to extract fundamental frequency (f0) and/or temporal fine structure cues (e.g., F1). Both of these features may be represented in frequency following responses (FFR) to bimodal speech. Thus, the goals of this study were to: 1) parametrically examine neural encoding of f0 and F1 in simulated bimodal speech conditions; 2) examine …

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 …

Neural Correlates Of Individual Differences In Speech-In-Noise Performance In A Large Cohort Of Cochlear Implant Users, Joel I. Berger, Phillip E. Gander, Subong Kim, Adam T. Schwalje, Jihwan Woo, Young Min Na, Ann Holmes, Jean M. Hong, Camille C. Dunn, Marlan R. Hansen, Bruce J. Gantz, Bob Mcmurray, Timothy D. Griffiths, Inyong Choi

Department of Communication Sciences and Disorders Faculty Scholarship and Creative Works

Objectives: Understanding speech-in-noise (SiN) is a complex task that recruits multiple cortical subsystems. Individuals vary in their ability to understand SiN. This cannot be explained by simple peripheral hearing profiles, but recent work by our group (Kim et al. 2021, Neuroimage) highlighted central neural factors underlying the variance in SiN ability in normal hearing (NH) subjects. The present study examined neural predictors of SiN ability in a large cohort of cochlear-implant (CI) users. Design: We recorded electroencephalography in 114 postlingually deafened CI users while they completed the California consonant test: a word-in-noise task. In many subjects, data were also collected …

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 …

Multicultural Assessment Practices: A Phenomenological Study Examining Speech-Language Pathologists' Self-Efficacy, Paola Jessica Flores

Doctoral Dissertations and Projects

The purpose of this phenomenological study was to understand speech-language pathologists’ (SLP) self-efficacy beliefs toward assessing culturally and linguistically diverse (CLD) students within public elementary schools in California. Bandura’s self-efficacy theory guided this study since it evaluated SLPs’ belief in their capacity to manage their motivation, behavior, and social environment to carry out appropriate assessment procedures for CLD students. As not all students from CLD backgrounds are accurately identified, gathering the SLPs’ lived experiences regarding current assessment practices helped provide insight into the appropriate identification of SLI. Participants included SLPs employed by rural public school districts in California, with students …

One Font Doesn’T Fit All: The Influence Of Digital Text Personalization On Comprehension In Child And Adolescent Readers, Shannon M. Sheppard, Susanne L. Nobles, Anton Palma, Sophie Kajfez, Marjorie Jordan, Kathy Crowley, Sofie Beier

Communication Sciences and Disorders Faculty Articles and Research

Reading comprehension is an essential skill. It is unclear whether and to what degree typography and font personalization may impact reading comprehension in younger readers. With advancements in technology, it is now feasible to personalize digital reading formats in general technology tools, but this feature is not yet available for many educational tools. The current study aimed to investigate the effect of character width and inter-letter spacing on reading speed and comprehension. We enrolled 94 children (kindergarten–8th grade) and compared performance with six font variations on a word-level semantic decision task (Experiment 1) and a passage-level comprehension task (Experiment 2). …

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 …

Factors Affecting The Healthcare Of Adults With Communication Difficulties Due To Autism Spectrum Disorder And/Or Intellectual And Developmental Disability, Kathryn L. Shady

MUSC Theses and Dissertations

Purpose: This dissertation explores the healthcare barriers and facilitators experienced by autistic adults and adults with intellectual and developmental disabilities (IDD) who have communication difficulties (CD).

Problem: Approximately 5-10% of Americans have CD, including difficulties such as stuttering, aphasia, apraxia, and other forms of language impairment(1,2). Communication difficulties are present in about 25-30% of autistic individuals and 57.9% of those with IDD, which accounts for a large and poorly studied portion of those with CD(3,4). Individuals with CD report negative healthcare experiences and decreased levels of satisfaction with healthcare providers secondary to practices such as communication solely with a …

Laryngeal Symptoms Related To Motor Phenotypes In Parkinson's Disease: A Systematic Review, Zoë Thijs Ph.D., Matthew Dumican

Communication Sciences and Disorders: Faculty Publications

Objective This study aimed to systematically review the associations between motor clinical phenotypes in Parkinson's disease (PD) and laryngeal disease symptoms. Laryngeal dysfunctions such as dysphonia and dysphagia are ubiquitous in people with Parkinson's disease (PwPD). Similar to other disease symptoms, they manifest variably across PwPD. Some of the variability within PD has been explained by clinical phenotypes. However, it is unclear how laryngeal symptoms of PD express themselves across these phenotypes.

Methods Five databases were searched (MEDLINE, CINAHL, Web of Science, Embase, Scopus) in May 2022. After the removal of duplicates, all retrieved records were screened. Cohort, case–control, and …
