The Effect Of Frequency Resolution On Intelligibility Sentence And Its Relevance To Cochlear Implant Design, Seth H. Roy

School of Computing: Dissertations, Theses, and Student Research

The purpose of this study is to understand how electrical stimulation (as opposed to acoustical stimulation) of the auditory nerve is used in cochlear implants. Speech is a complex signal that changes rapidly in time and frequency domains. Since phonemes (the smallest unit of speech that distinguishes words) depend on nuanced differences in frequency patterns, it would be expected that a signal with drastically reduced frequency information would be of limited value for conveying speech. Such a frequency-poor signal is the object to be investigated in the present work. It is also the basis of the way speech is represented …

Prevalence And Trends Of Childhood Hearing Loss Based On Federally-Funded National Surveys: 1994–2013, Tyson S. Barrett, Karl R. White

Journal of Early Hearing Detection and Intervention

A recent highly cited publication, using data from the National Health and Nutrition Examination Survey (NHANES), concluded that the prevalence of childhood hearing loss in the United States is increasing (Shargorodsky, Curan, Curhan, & Eavey, 2010). This article examines the accuracy of that conclusion based on additional data from three nationally-representative surveys of childhood health. Using data from NHANES, the National Survey of Children’s Health (NSCH), and the National Health Interview Survey (NHIS), logistic regression was used to assess trends from audiometry-measured and parent-reported childhood hearing loss.

In contrast to prior research, the results were highly conflicting. NHANES suggested both …

A Comprehensive Review Of The 2016 Asha Code Of Ethics, Robin L. Edge Ph.D., Ccc-Slp, Bess Sirmon-Taylor Ph.D., Ccc-Slp, Raul F. Prezas Ph.D., Ccc-Slp

Journal of Human Services: Training, Research, and Practice

The American Speech-Language-Hearing Association (ASHA) initially implemented a Code of Ethics in 1952, and has periodically revisited the content of the document with revisions to reflect the expanding scope of practice within speech-language pathology and audiology and to clarify certain concepts. Code revision is a cyclical mandated task of the ASHA Board of Ethics conducted to assure accuracy, currency, and completeness of this most important document (Solomon-Rice & O’Rourke, 2016). The current version of the Code of Ethics (2016) was modified from the previous version (2010r), with an updated preamble, definitions of related vocabulary, and re-organized language in the principles. …

A New Articulation Test Applied To A Selected Group Of Children Living In The State Of New Mexico, Robert Edwin Burkhalter

Speech and Hearing Sciences ETDs

Bilingualism is much more prevalent in the United States than is commonly believed. Goodykoontz points out that "one child in every five, aged fourteen years or under, is of foreign born or mixed parentage." Since our country is still a melting pot of the world where large numbers of citizens converse in other tongues and where many children still enter our schools without speaking a word of English, the problem of bilingualism and foreign dialect will frequently be encountered by the school teacher.

Perception And Production Of /V/ And /W/ In Hindi Speakers, Vikas Grover

Dissertations, Theses, and Capstone Projects

This dissertation examines the ability of Hindi speakers to identify, discriminate and produce two English phonemes /v/ and /w/ which are difficult for Hindi speakers to distinguish. In Hindi, /v/ and /w/ are used interchangeably. This pattern of use has transferred to Indian English, resulting in English /v/ and /w/ words showing variable pronunciations (e.g., “whale” or “vale” for the word “whale”). Hindi speakers were asked to identify, discriminate and produce tokens of /v/ and /w/. This study also examined whether experience with American English, related to the length of residence (LOR) in the US affects Hindi listeners’ perception and …

Outcomes Of Speech And Language Pilot Program For International Students, Kelly Fussman

Mahurin Honors College Capstone Experience/Thesis Projects

Universities in the United States host a substantial number of international students every academic year. As of the 2015-2016 academic year, Western Kentucky University, located in south-central Kentucky, alone hosts over 1,400 international students. These students often face a number of challenges upon arrival in the United States, especially when it comes to language and cultural differences. A considerable body of research indicates that international students’ educational performance and outcomes are significantly impacted by their cultural identities, psychological and sociocultural experiences, and attitudes in relation to English-speaking societies. Many international students attribute academic and social difficulties to a lack of …

Semantic Knowledge Use In Discourse Produced By Individuals With Anomic Aphasia, Stephen Kintz, Heather Harris Wright, Gerasimos Fergadiotis

Speech and Hearing Sciences Faculty Publications and Presentations

Background---Researchers have demonstrated that people with aphasia (PWA) have preserved semantic knowledge (Dell et al., 1997; Jefferies & Lambon Ralph, 2006). However, Antonucci (2014) demonstrated that some PWA have impaired access to certain types of knowledge more than others. Yet, all these studies used single concepts. It has not been demonstrated whether PWA have difficulty accessing certain types of features within a discourse sample.

Aims—The main goals of this study were to determine if semantic knowledge and two category types were used differently within discourse produced by participants with anomic aphasia and healthy controls.

Method & Procedures—Participants …

This work is an attempt to provide a complete picture of these programs and to detail the history and growth of the Audiology Program at the University of Nebraska-Lincoln. When the author came to the University in 1977 audiology was already well established at the University as well as in the State. After joining the faculty, the author served in the capacity of Coordinator of the Audiology and Hearing Science Program from 1977 until …

Opening And Closing Jaw Movements Of Young Children Who Stutter., Victoria Tumanova, Anthony P. Buhr, Patricia Zevrowski, Jerald Moon, Richard Arenas, Torrey Loucks

Communication Sciences and Disorders - All Scholarship

Objective: In this longitudinal study, we investigated the hypothesis that kinematic measures of jaw movement produced by children who stuttered (CWS) and children who did not stutter (CWNS) would differ between opening and closing speech gestures, across phonetic contexts, and across development.

Methods: Mean amplitude, velocity, and duration of jaw opening and closing gestures during repeated productions of bilabial syllables were analyzed longitudinally at 1-year intervals for 13 CWS and 7 children CWNS. The utterances ranged across four phonetic contexts: single-syllable, two-syllable, three-syllable, and six-syllable. For jaw movement transduction, a strain gauge was attached to a football helmet in a …

Analyzing Spelling Errors By Linguistic Features Among Children With Learning Disabilities, Christine Johnson

USF Tampa Graduate Theses and Dissertations

In order to spell fluently and accurately, phonology, orthography, and morphology must be integrated and stored into long term memory (Berninger & Richards, in press; Berninger, Nagy, Tanimoto, Thompson, Abbott, 2015). Children with dysgraphia, dyslexia, and OWL-LD have specific deficits in linguistic processing that impede the cross-mapping of these linguistic elements. This study analyzes the frequency and nature of spelling errors produced by children with dysgraphia, dyslexia, and OWL-LD during an academic writing task in order to determine if known deficits in linguistic processing affect the type and severity of spelling errors made by these children.

The present study analyzed …

Analysis Of Patterns In Handwritten Spelling Errors Among Students With Various Specific Learning Disabilities, Laura Ann Winkler

USF Tampa Graduate Theses and Dissertations

Students diagnosed with specific learning disabilities struggle with spelling accuracy, but they do so for different reasons. For instance, students with dysgraphia, dyslexia, and oral-written language learning disability (OWL-LD) have distinct areas of weakness in cognitive processing and unique difficulties with the linguistic features necessary for accurate spelling (Silliman & Berninger, 2011). This project considered the spelling errors made by such students to determine if their unique learning profiles lead to distinct misspelling patterns.

Academic summaries handwritten by 33 students diagnosed with dysgraphia (n=13), dyslexia (n=15), and OWL-LD (n=5) were analyzed for type/complexity and …

Effects Of A Novel Right Brain Intervention On Stuttering In Familiar And Structured Speech Tasks, Josalyn Elizabeth Perry

USF Tampa Graduate Theses and Dissertations

Over 3 million Americans are disfluent due to developmental stuttering. Current evidence-based treatments typically consist of a rigorous schedule of intensive therapy, followed by the need for maintenance of skills, placing high demands on self-monitoring of one’s speech at all times. Relapse after treatment is very common, at 84%. The demand for further research into treatment possibilities for stuttering is on the forefront. Previous research has connected neural activations in people who stutter (PWS) and people with chronic nonfluent aphasia. The aim of this study was to determine if a novel intervention, based on a treatment for anomia, would change …

Tongue Twisters Quantified: Ultrasound Analysis Of Speech Stability And Speech Errors, Karen Reddick

USF Tampa Graduate Theses and Dissertations

This thesis investigates errors on speech sounds (or phonemes) produced in laboratory speech stimuli designed to generate phonological onset errors. The present study adds to the literature on phonological speech errors with an instrumental analysis of tongue posture during speech error production and an investigation of the nature of speech errors as unintended variation in articulation.

This study utilized ultrasound instrumentation to visualize speech errors made on velar and alveolar stop consonants at the point of stop closure. Two types of errors were of interest, categorical errors and gradient errors. Categorical errors are those that are heard by the listener …

Interspeech Posture In Spanish-English Bilingual Adults, Merrily Rose Shary

USF Tampa Graduate Theses and Dissertations

Interspeech posture (ISP) is a term used to define the position of a person’s articulators when they are preparing to speak. Research suggests that ISP may be representative of a speaker’s phonological knowledge in a particular language, as determined empirically with ultrasound measures of the tongue in English-French bilinguals (Wilson & Gick, 2014). It is possible, therefore, that measuring ISP could be a diagnostic tool for determining phonological knowledge in bilingual speakers. However, more information on ISP in typical adult bilingual speakers is needed before diagnostic claims can be made. For example, ISP is believed to be language specific, and …

Effects Of A Novel Right Brain Intervention On Stuttering Frequency In Unfamiliar Speech Tasks, Chelsea Beatrice Stewart

USF Tampa Graduate Theses and Dissertations

Developmental stuttering persists in approximately 1% of the United States population. Stuttering has been shown to impact overall quality of life. The present study examines the effects of a Novel Right Brain Intervention on two female participants with persistent developmental stuttering. The aim of the study was to determine whether encouraging greater activation of the right hemisphere, specifically the pre-SMA, via complex left-handed movements, prior to speech production, would lead to a reduced stuttering frequency and severity in people who stutter (PWS). It was hypothesized that each participant would reduce stuttering symptoms and behaviors following the intervention due to the …

Language-Mixing In Discourse In Bilingual Individuals With Non-Fluent Aphasia, Avanthi Paplikar

Dissertations, Theses, and Capstone Projects

Language-mixing (LM) as defined by Chengappa (2009, p. 417) is an “intra-sentential phenomenon referred to as the mixing of various linguistic units (morphemes, words, modifiers, phrases, etc.), primarily from two participating grammatical systems”. LM is influenced by grammatical, environmental, and social constraints (e.g., Milroy & Wei, 1995; Bhat & Chengappa, 2005). Researchers have suggested that LM in patients with aphasia is a communicative strategy used to achieve successful exchanges between speakers; the effectiveness of this mixing, however, had yet to be demonstrated quantitatively.

In the current study we investigated whether LM is present in bilingual speakers with aphasia, and if …

Annexin A5 Is The Most Abundant Membrane-Associated Protein In Stereocilia But Is Dispensable For Hair-Bundle Development And Function, Jocelyn F. Krey, Meghan Drummond, Sarah Foster, Edward Porsov, Sarath Vijayakumar, Dongseok Choi, Karen Friderici, Sherri M. Jones, Alfred L. Nuttall, Peter G. Barr-Gillespie

Department of Special Education and Communication Disorders: Faculty Publications

The phospholipid- and Ca²⁺-binding protein annexin A5 (ANXA5) is the most abundant membrane-associated protein of ~P23 mouse vestibular hair bundles, the inner ear’s sensory organelle. Using quantitative mass spectrometry, we estimated that ANXA5 accounts for ~15,000 copies per stereocilium, or ~2% of the total protein there. Although seven other annexin genes are expressed in mouse utricles, mass spectrometry showed that none were present at levels near ANXA5 in bundles and none were upregulated in stereocilia of Anxa5^−/− mice. Annexins have been proposed to mediate Ca²⁺-dependent repair of membrane lesions, which could be part of the …

Cultural Competence And Ethical Decision Making For Health Care Professionals, Brenda Louw

ETSU Faculty Works

Cultural competence and ethical decision making are two separate, yet intrinsically related concepts which are central to services rendered by all health care professionals. Cultural competence is based on ethical principles and informs ethical decision making. In spite of this important connection, the interrelationship of these two concepts does not receive the attention it deserves in the literature. This issue is addressed by appraising the training and assessment of cultural competence and ethical decision making in the health care professions. The integrated relationship of these two concepts is illustrated within the broader contexts of higher education, research and clinical practice. …

Reflection: Effect Of Age On Auditory Brainstem Responses In Mice With Epha4 Mutations, Erica L. Hoogerland

Senior Honors Projects, 2010-2019

Presbycusis, or age-related hearing loss is a condition that affects approximately 40% of the population over 65 years of age (Gates & Mills, 2005). Studying the effects of EphA4 mutations (wild type, heterozygous, and homozygous) mice is fundamental in understanding the relationship between onset of age-related hearing loss, in both the mammalian population and the human population. In order to further understanding of age-related hearing loss, the researchers evaluated thirty-six mice in a preliminary study from two months to nine months of age. Following data analysis, the researchers confirmed the results by continuing a second round of testing. The hearing …

Build-Up Effect Of Auditory Stream Segregation Using Amplitude-Modulated Narrowband Noise, Harley J. Wheeler

Senior Honors Projects, 2010-2019

Recent psychoacoustic experiments (Böckmann-Barthel et al., 2014; Deike et al., 2012) have re-examined research regarding stream segregation and the build-up effect. Stream segregation is the ability to discern auditory objects within a stream of information, such as distinguishing one voice amongst background noise or an instrument within an orchestra. Initial works examining this topic proposed that auditory information is not immediately distinguished as various streams, but rather that differences accumulate over time, allowing listeners to segregate information following a period of build-up (i.e., the build-up effect); whereas more current findings indicate a build-up period is unnecessary for segregation. This experiment’s …

Release From Masking: Behavioral And Physiological Masking Level Differences, Sarah L. Hodgson

Dissertations, 2014-2019

Binaural hearing offers several advantages over monaural hearing and is believed to be one factor that is involved in the ability to understand speech in background noise. Binaural hearing involves analysis of interaural timing and intensity differences in signals arriving at the two ears which provides listeners with sound localization cues as well as signal in noise detection. When sounds arrive at each ear at slightly different times, there may be a release from the effects of background noise, allowing listeners to detect softer sounds in noise. Masking Level Differences (MLDs) have been widely used to evaluate behavioral binaural processing. …

Prepulse Inhibition Of The Acoustic Startle Reflex To Obtain A Psychometric Function In Mice, Robyn Browne

Dissertations, 2014-2019

The acoustic startle reflex (ASR) is an automated motor response to an unexpected and intense auditory stimulus (Ouagazzal, Reiss, & Romand, 2006). When an audible ‘prepulse’ stimulus is presented before the intense, startle-evoking stimulus (SES); the startle reflex response is reduced and this is known as prepulse inhibition (PPI). The degree of ASR inhibition serves as a measure of the behavioral salience of the prepulse (Carlson & Willott, 1996). This study aimed to obtain a psychometric function from the amount of PPI of the ASR that resulted from varying intensity levels of a prepulse stimulus (PPS).

Twelve mice were used …

Effect Of Epha4 Signaling Mutations On Auditory Function, Michelle R. Gerringer

Dissertations, 2014-2019

Neural pathways underlie the ability of the auditory system to perceive sound. Organization of neural pathways into functional auditory circuitry is accomplished in part by Eph and ephrin signaling proteins. One of these signaling proteins, the EphA4 receptor tyrosine kinase protein, acts as an axon-guidance molecule to aid in target selection and to maintain tonotopicity in the auditory brainstem and midbrain. Genetic mutations of the EphA4 protein have been shown to affect structural auditory development, but there is limited research which shows the functional effects of these mutations. The goal of the present study was to determine the functional effects …
