Covariation Among Vowel Height Effects On Acoustic Measures, Jeffrey J. Berry, Maura Jones Moyle

Speech Pathology and Audiology Faculty Research and Publications

Covariation among vowel height effects on vowel intrinsic fundamental frequency (IF0), voice onset time (VOT), and voiceless interval duration (VID) is analyzed to assess the plausibility of a common physiological mechanism underlying variation in these measures. Phrases spoken by 20 young adults, containing words composed of initial voiceless stops or /s/ and high or low vowels, were produced in habitual and voluntarily increased F0 conditions. High vowels were associated with increased IF0 and longer VIDs. VOT and VID exhibited significant covariation with IF0 only for males at habitual

Audibility As A Predictor Of Speech Recognition And Listening Effort, Ryan W. Mccreery

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

Two studies were conducted to evaluate how audibility influences speech recognition and measures of working memory in children with normal hearing. Specifically, audibility limitations related to background noise and limited bandwidth were analyzed, as these factors are characteristic of the listening conditions encountered by children with hearing loss who wear hearing aids.

In the first study, speech recognition was measured for 117 children and 18 adults with normal hearing. Stimulus bandwidth and the level of background noise were varied systematically in order to evaluate predictions of audibility based on the Speech Intelligibility Index. Results suggested that children with normal hearing …

Unreported Concussion In High School Football Players, Princess Arcelia Puga

Open Access Theses & Dissertations

Recent research in sport-related concussions has begun to reveal more about the specific hazards of high school football. However, the national reports of incidence/prevalence of concussions in this population appear to be inaccurate, because only emergency department (ED) visits are accounted for in reporting the number of concussions sustained in football. Purpose: The purpose of this study was to investigate whether there is a statistically significant difference between the frequencies of concussion reports by athletic trainers (ATC) versus hospital records on concussion in high school football players in El Paso, Texas. Method: A questionnaire was delivered to athletic trainers through …

Speech-Language Pathologists' Reports Of Interprofessional Collaboration And Exposure During Graduate School, Carly Ruth Robalin

Open Access Theses & Dissertations

ABSTRACT

Although the importance and benefits of interprofessional education (IPE) and interprofessional collaboration (IPC) in healthcare have been well demonstrated, the majority of graduate programs in speech-language pathology (SLP) only offer discipline-specific coursework and related experiences. Purpose: The purpose of this study is to explore SLPs' perceptions of their graduate programs' success at preparing them to be interprofessional team-members in the medical work setting. Method: Medically-based SLPs in five Texas cities responded to a survey addressing IPE and IPC. Responses were collected regarding: 1. Interprofessional exposure to physical therapy (PT) and occupational therapy (OT) during graduate school, 2. IPE opportunities …

Central Neural And Behavioral Correlates Of Voice Secondary To Induced Unilateral Vocal Fold Paralysis, Ashwini Joshi

University of Kentucky Doctoral Dissertations

Understanding the involvement of the central nervous system (CNS) in voice production is essential to incorporating principles of neuroplasticity into therapeutic practice for voice disorders. Early steps to attaining this goal require the identification of specific neural biomarkers of the changes occurring in the CNS from a voice disorder and its subsequent treatment. In the absence of an adequate animal vocalization model, the larynx has not been acutely and reversibly perturbed to concurrently examine the effect on both peripheral and central processing of the altered input/output.

Using a unique, reversible perturbation approach, it was the purpose of this study to …

Perspective Shifting In Relative Clauses By Elementary-Aged Spanish-English Bilinguals: A Cross-Linguistic Study, Xigrid Tayri Soto

USF Tampa Graduate Theses and Dissertations

Language-specific theories of sentence processing suggest that individuals interpret sentences based on the characteristics of their native language (e.g., Bates & MacWhinney, 1989). As such, competing linguistic cues are taken into account (including word order, morphology, and animacy) and the cue selected is most likely to yield a correct interpretation in the native language. However, research in this area has produced conflicting results. MacWhinney (2005) has proposed that examining the role of perspective shifting in sentence comprehension may demonstrate how cognitive and syntactic factors work together to facilitate sentence comprehension. The aim of the current study is to investigate the …

Hemispheric Differences In Specificity Effects In Talker Identification, Julio Gonza´Lez, Teresa Cervera-Crespo, Conor T. Mclennan

Psychology Faculty Publications

In the visual domain, Marsolek and colleagues (1999, 2008) have found support for two dissociable and parallel neural subsystems underlying object and shape recognition: an abstract-category subsystem that operates more effectively in the left cerebral hemisphere (LH), and a specific-exemplar subsystem that operates more effectively in the right cerebral hemisphere (RH). Evidence of this asymmetry has been observed in priming specificity for linguistic (words, pseudoword forms) and nonlinguistic (objects) stimuli. In the auditory domain, the authors previously found hemispheric asymmetries in priming effects for linguistic (spoken words) and nonlinguistic (environmental sounds) stimuli. In the present study, the same asymmetrical pattern …

Monitoring Carboplatin Ototoxicity With Distortion-Product Otoacoustic Emissions In Children With Retinoblastoma, Shaum Bhagat, Johnnie Bass, Stephanie White, Ibrahim Qaddoumi, Matthew Wilson, Jianrong Wu, Carlos Rodriguez-Galindo

Faculty Publications

ObjectiveCarboplatin is a common chemotherapy agent with potential ototoxic side effects that is used to treat a variety of pediatric cancers, including retinoblastoma. Retinoblastoma is a malignant tumor of the retina that is usually diagnosed in young children. Distortion-product otoacoustic emission tests offer an effective method of monitoring for ototoxicity in young children. This study was designed to compare measurements of distortion-product otoacoustic emissions obtained before and after several courses of carboplatin chemotherapy in order to examine if (a) mean distortion-product otoacoustic emission levels were significantly different; and (b) if criterion reductions in distortion-product otoacoustic emission levels were observed in …

Listener Reliability And Agreement Of A Brief Intelligibility Rating Task, Cai Ewing-Buck

Speech and Hearing Sciences ETDs

PURPOSE: This study addresses the development of the I-RAVN Test of Speech Intelligibility, an assessment instrument designed to identify which speech components most affect speech intelligibility. The I-RAVN consists of ratings of overall intelligibility, and ratings of four speech components: rate/rhythm/prosody, articulation, voice quality/breath support, and nasality using a rating scale technique adapted from the CAPE-V instrument for voice. This study seeks to establish that listeners can reliably rate overall intelligibility and the four speech components in speakers with dysarthria. METHODS: Twenty-two graduate students listened to recordings from 24 talkers (7 normal, 6 with Parkinson Disease, 11 with oculopharyngeal muscular …

Intelligibility Of Electrolarynx Speech Using A Novel Actuator, Brian Madden, Mark Nolan, Ted Burke, James Condron, Eugene Coyle

Conference Papers

During voiced speech, the larynx provides quasi-periodic acoustic excitation of the vocal tract. Following a laryngectomy, some people speak using an electrolarynx which replaces the excitatory function of the absent larynx. Drawbacks of conventional electrolarynx designs include the buzzing monotonic sound emitted, the need for a free hand to operate the device, and difficulty experienced by many laryngectomees in adapting to its use. Despite these shortcomings, it remains the preferred method of speech rehabilitation for a substantial minority of laryngectomees. In most electrolarynxes, mechanical vibrations are produced by a linear electromechanical actuator, the armature of which percusses against a metal …

Phonological Development In Hearing Children Of Deaf Parents, Erin N. Toohey

Honors Scholar Theses

Phonological development in hearing children of deaf parents Dr. Diane Lillo-Martin 5/9/2010 The researcher wishes to determine the significance of a unique linguistic environment on the effects of phonological development. The research examines whether 3 hearing children of deaf parents, hereafter referred to as CODAs, have inconsistencies, as compared to children in a typical linguistic environment, in their syllable structure, phonological processes or phonemic inventories. More specifically, the research asks whether their speech is more consistent with children of typical environments or more similar to children with phonological delays or disorders or articulation disorders. After the examination of these three …

Coherence In Stories Told By Adults With Aphasia, Heather Harris Wright, Anthony Koutsoftas, Gerasimos Fergadiotis, Gilson Capilouto

Speech and Hearing Sciences Faculty Publications and Presentations

Discourse coherence is the conceptual organization of discourse and it can be subdivided into two types: global and local. Of interest for the current study is global coherence; that is, how the discourse relates to the overall topic (Glosser & Deser, 1990). Coherence has been measured in persons with aphasia (PWA) using different elicitation tasks (e.g., recounts, story retelling, event-casts) and different scoring methods (ie., rating scales, coherence, violations, total counts) and results have varied across studies (Christianson, 1995; Coelho & Flewellyn, 2003; Glosser & Deser, 1990; Ulatowska, et al., 2004). These differences may reflect differences in how coherence is …

Perception And Identification Of Voice Disorders: A Comparison Study Between Hispanic And Non-Hispanics, Jacqueline Nicole Lopez

Open Access Theses & Dissertations

The extent of public education in the Hispanic population regarding voice disorders has been unidentified thus far, motivating the current study to assess knowledge and perception of functional and organic voice disorders among Hispanic individuals in the El Paso region. The project involved an experimental research design to investigate whether demographic variables influenced the accuracy of knowledge of voice disorders in the general population residing in the Greater El Paso Region. Results indicate that the majority of the participants perceive articulation, fluency, and voice disorders as interchangeable and are unaware of the role of medical and rehabilitation professionals in the …

Psychometric Properties Of The Pyramids And Palm Trees Test, Gerasimos Fergadiotis, Heather Wright, Gilson Capilouto

Speech and Hearing Sciences Faculty Publications and Presentations

The Pyramids and Palm Trees Test (PPT) is a nonverbal measure of semantic memory that has been frequently used in previous aphasia, agnosia, and dementia research. Very little psychometric information regarding the PPT is available. The purpose of this study was to investigate the psychometric properties of the PPT in a population of healthy college students. Results indicated that the PPT achieved poor test–retest reliability, failed to obtain adequate internal consistency, and demonstrated poor convergent validity, but showed acceptable discriminant validity. The results of this study suggest that the PPT lacks acceptable reliability and validity for use with a college …
