The Harding University Speech Clinic As A Community Outreach Program In White County, Melaney Binkley

McNair Scholars Research

A university speech clinic provides, at no cost to clients, more selective, limited speech and language services by a student clinician in the Communication Sciences and Disorders program under the supervision of a certified speech-language pathologist (SLP). A private speech clinic requires certified speech-language pathologists and assistants. The purpose of this study was to analyze the Harding University Speech Clinic’s client population, particularly in terms of socioeconomic status, since the city in which the university is located has a higher average poverty rate than the state. Additionally, the study sought to measure the level of client satisfaction with the services …

Toward Generalizable Machine Learning Models In Speech, Language, And Hearing Sciences: Estimating Sample Size And Reducing Overfitting, Hamzeh Ghasemzadeh, Robert E Hillman, Daryush D Mehta

Student and Faculty Publications

PURPOSE: Many studies using machine learning (ML) in speech, language, and hearing sciences rely upon cross-validations with single data splitting. This study's first purpose is to provide quantitative evidence that would incentivize researchers to instead use the more robust data splitting method of nested

METHOD: First, the significant impact of different cross-validations on ML outcomes was demonstrated using real-world clinical data. Then, Monte Carlo simulations were used to quantify the interactions among the employed cross-validation method, the discriminative power of features, the dimensionality of the feature space, the dimensionality of the model, and the sample size. Four different cross-validation methods …

The Adverse Childhood Experiences Identification Gap In Speech Language Pathology, Mallory Prior

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

Children exposed to adverse childhood experiences, a variety of potentially traumatic events occurring within the first 18 years of life, are at increased risk for speech and language disorders. Due to the high prevalence of trauma and its lasting effects, it is almost guaranteed that children who are experiencing the ongoing effects from adversity will be found on practicing Speech Language Pathologists’ caseloads. This scoping review was designed to identify current screening practices of Speech Language Pathologists (SLP) in comparison to other professionals (e.g., allied health and education), as well as additional information related to screening procedures for SLPs. The …

Abstract 1- Introduction: Charcot-Marie-Tooth (CMT) disease is a rare and chronic hereditary disorder that causes motor and sensory damage to the peripheral nervous system. As the disease progresses, hearing sensitivity may worsen. Case Presentation: A young adult-aged patient presented to the clinic with congenital hearing loss and difficulty with conversational speech in quiet and noisy conditions. Discussion: When encountering a patient with CMT, clinicians should be cognoscente of amplification options, especially if nerve pathways begin to deteriorate. When audiologic testing reveals a progression of hearing loss, alternative amplification may be indicated because conventional hearing aids may not provide enough …

Audiological Intervention For Late-Identified Children And Teenagers With Hearing Loss, Melissa Wiedeman, Antony Joseph

AuD Capstone Projects - Communication Sciences and Disorders

Abstract 1 - Introduction: The family of every child referred for definitive care after a newborn hearing screening should follow up with an audiologist to rule out hearing impairment. Early identification, diagnosis, and intervention are crucial for individualized planning and outcomes. Children who need binaural amplification and are not managed appropriately become exposed to sound deprivation, which leads to diminished speech audibility, sound localization, and speech and language development. Case Presentation: A young child presented to the clinic with an unspecified bilateral mild to moderate hearing loss at 500, 2000, and 4000 Hz. Discussion: Children with monaural amplification have shown …

FIU Electronic Theses and Dissertations

This study examined the effects of Flow Phonation Voice Exercises on vocal measures in undergraduate student singers. Whereas these exercises have provided positive outcomes in individuals with vocal hyperfunction, the use of these exercises in potentially enhancing the singing voice has not been explored. A total of 10 participants were randomly assigned into an experimental group (n = 6), that received 5 sessions of the Flow Phonation Voice Exercises across 5 weeks, and a control group (n = 4) which did not receive the treatment. Changes in auditory-perceptual, acoustic, subjective respiratory, quality-of-life and fatigue related measures compared across two groups. …

Perceptions Of Speech-Language Pathologists On Childhood Bilingualism, Sherlie V. Paz

FIU Electronic Theses and Dissertations

A total of 320 Speech-Language Pathologists (SLPs) completed a survey stating their perceptions on childhood bilingualism for typically developing children and children with disabilities. Based on the number of significant responses, 292 participants were analyzed utilizing a binary logistic regression to identify whether SLPs thought childhood bilingualism was advantageous or neutral, while incorporating the predictors of bilingual status and bilingual education received. Additionally, a content analysis was conducted on 173 participants who chose to respond to an open-ended question stating their additional perceptions on childhood bilingualism. Results revealed that bilingual status did not predict the probability of an advantageous perception …

The Effects Of Acidic Foods On Vocal Quality Of Vocally Healthy Individuals, Melissa Barbieri

FIU Electronic Theses and Dissertations

The purpose of the current study was to examine the relationship between the consumption of acidic liquids on the vocal quality of vocally healthy individuals. Acidic foods and liquids are known to be possible causes of common voice disorders because of their putative effect on systemic hydration of the vocal folds impacting their viscoelastic properties and eventually affecting vocal quality, as they are found in over 50% of dysphonic patients (Karkos et al., 2007). This study investigated the effects of acidic foods on vocal quality in comparison to the effects of non-acidic/alkaline beverages in vocally healthy individuals.

Creating A Theoretical Framework To Underpin Discourse Assessment And Intervention In Aphasia, Lucy Dipper, Jane Marshall, Mary Boyle, Deborah Hersh, Nicola Botting, Madeline Cruice

Department of Communication Sciences and Disorders Faculty Scholarship and Creative Works

Discourse (a unit of language longer than a single sentence) is fundamental to everyday communication. People with aphasia (a language impairment occurring most frequently after stroke, or other brain damage) have communication difficulties which lead to less complete, less coherent, and less complex discourse. Although there are multiple reviews of discourse assessment and an emerging evidence base for discourse intervention, there is no unified theoretical framework to underpin this research. Instead, disparate theories are recruited to explain different aspects of discourse impairment, or symptoms are reported without a hypothesis about the cause. What is needed is a theoretical framework that …

Providing assessment and treatment tools that best serve multilingual individuals with aphasia and unpacking the variables and mechanisms that underlie response to treatment have emerged as goals of several recent studies. Additionally, while findings are still …

Strengthening The Semantic Verb Network In Multilingual People With Aphasia: Within- And Cross-Language Treatment Effects, Aviva Lerman, Mira Goral, Lisa Edmonds, Loraine K. Obler

Publications and Research

In multilingual people, semantic knowledge is predominantly shared across languages.
Providing semantic-focused treatment to people with aphasia has been posited to strengthen
connectivity within association cortices that subserve semantic knowledge. In multilingual people, such treatment should result in within- and cross-language generalisation to all languages, although not equally. We investigated treatment effects in two multilingual participants with aphasia who received verb-based semantic treatment in two pre-stroke highly
proficient languages. We compared within- and cross-language generalisation patterns across languages, finding within- and cross-language generalisation after treatment in the less-impaired, pre-morbidly more-proficient first-acquired language (L1). This observation supports the theory that connectivity …

Infants’ Discrimination Of Consonant Contrasts In The Presence And Absence Of Talker Variability, Carolyn Quam, Lauren Clough, Sara Knight, Louann Gerken

Speech and Hearing Sciences Faculty Publications and Presentations

To learn speech‐sound categories, infants must identify the acoustic dimensions that differentiate categories and selectively attend to them as opposed to irrelevant dimensions. Variability on irrelevant acoustic dimensions can aid formation of robust categories in infants through adults in tasks such as word learning (e.g., Rost and McMurray, 2009) or speech‐sound learning (e.g., Lively et al., 1993). At the same time, variability sometimes overwhelms learners, interfering with learning and processing. Two prior studies (Kuhl & Miller, 1982; Jusczyk, Pisoni, & Mullennix, 1992) found that irrelevant variability sometimes impaired early sound discrimination. We asked whether variability would impair or facilitate discrimination …

The Ongoing Disparity Between Early Intervention Services And Those Who Need Them, Addison Goerl

Honors Theses

Although early intervention (EI) services have been shown to be highly effective and beneficial for young children, only 12% of those who qualify at 24 months receive services (Feinberg et al., 2011). There is a myriad of barriers that impedes access to EI services for those who need them. These barriers include myths about development and intervention, parent’s concerns being ignored, social inequalities limited access to early intervention, systemic barriers within the professional world, unperceived benefits of intervention, and limited communication flow to parents. However, there are some supports that help more families access EI services including doctors, early interventionists, …

Variables And Mechanisms Affecting Response To Language Treatment In Multilingual People With Aphasia, Mira Goral, Aviva Lerman

Publications and Research

Background: Despite substantial literature exploring language treatment effects in multilingual people with aphasia (PWA), inconsistent results reported across studies make it difficult to draw firm conclusions. Methods: We highlight and illustrate variables that have been implicated in effecting cross-language treatment effects in multilingual PWA. Main contribution: We argue that opposing effects of activation and inhibition across languages, influenced by pertinent variables, such as age of language acquisition, patterns of language use, and treatment-related factors, contribute to the complex picture that has emerged from current studies of treatment in multilingual PWA. We propose a new integrated model—Treatment effects in Aphasia in …
