Investigating Self-Perception Of Speech And Motivation For Return To Intervention For Post Cochlear Implantation In Young Adults, Madison Henry

Electronic Theses and Dissertations

Introduction: Cochlear Implants (CI) are designed to address severe to profound hearing loss. When implantation occurs after language develops, it is referred to as post-lingual (PL) implantation. Currently, no interventions have been identified to address the communication challenges that young adults with PL-CIs may face after they complete post-CI rehabilitation services. This study analyzes if an individualized intervention plan is beneficial for a person with PL-CIs when experiencing changing communication demands in the transition to college or the workforce. Methodology: Baseline assessments were conducted; the results of which allowed for the establishment of four co-constructed goals. These goals were targeted …

Numerical Investigation Of Subglottal Stenosis Effects On Human Voice Production, Dariush Bodaghi

Electronic Theses and Dissertations

This dissertation aimed to advance knowledge of how subglottal stenosis impacts voice production physiology. An in-house fluid-structure-acoustic interaction approach based on the hydrodynamic/acoustic splitting technique was employed. This technique was rigorously verified for simulating phonation by matching the acoustic behavior to a compressible flow solver for phonation-relevant geometries. Simulations of an idealized 2D vocal tract model demonstrated the effects of supraglottal acoustic resonance on vocal fold kinematics and glottal flow waveform. Results showed that the acoustic coupling between higher harmonics and formats generated pressure oscillations, modifying vocal fold dynamics and glottal flow rate.

A major novelty was the incorporation and …

The Effect Of Telepractice On Vocal Interaction Between Provider, Deaf And Hard-Of-Hearing Pediatric Patients, And Caregivers., Abigail Betts

Electronic Theses and Dissertations

The purpose of this thesis is to examine how telepractice affects a vocal interaction between a speech-language pathologist (SLP), deaf and hard-of-hearing children who received cochlear implants (n = 7), and caregivers as they engage in speech-language interventions conducted in-person and via telepractice (tele). Frequency of vocalizations, vocal turns, pause duration, fundamental frequency (F0) mean and range, utterance duration, syllable rate per utterance duration, and mean length of utterance (MLU) were examined. The SLP vocalized more during in-person than tele-sessions, opposite result for the mother. There were more SLP-child turns during in-person sessions than tele-sessions; opposite result for mother-child turns. …

The Perception And Strategies Of Building Rapport With Children With Autism Spectrum Disorder Via Telepractice, Anna Cathryn Wall

Electronic Theses and Dissertations

Telepractice is a growing method in providing services in the profession of Speech-Language Pathology. One question with this growing method is, how do we build rapport when using telepractice? In this study, we intended to find what pediatric SLPs' perceptions and strategies of building rapport via telepractice is with children with autism spectrum disorder (ASD) ages 5-12, and children’s age was considered as an influential factor. While previous studies have focused on perceptions, we wanted to know what SLPs are doing in order to build rapport with their clients when using telepractice. We reached out to 223 SLPs and there …

School-Based Speech-Language Pathologist's Perceptions Of Sensory Food Aversions In Children, Ellen Monroe

Electronic Theses and Dissertations

Sensory Food Aversions occur frequently in children who are likely to appear on Speech-Language Pathologist’s (SLP’s) caseloads. The lack of research regarding intervention for Sensory Food Aversions in schools and the assertion of a gap in school-based services for children with feeding disorders was a significant indicator for the need of the study. A quantitative, descriptive, exploratory research design was selected using a self-developed questionnaire in order to exploreschool-based SLP’s perceptions of their knowledge and skills related to Sensory Food Aversions, as well as determine resources available for working with this population. Findings from the study suggest a need for …

Carer Information Needs Following A Family Member's Right Hemisphere Stroke, Christyn Davidson

Background: Previous studies have explored information needs for carers of persons with aphasia; however, there is minimal research on information needs of carers with right hemisphere disorder (RHD). RHD describes cognitive and communication impairments a person experiences following a right hemisphere stroke or brain injury. Carers have an important role in rehabilitation and the long-term quality of life of a person with RHD. This study explores the information needs for carers following a family member’s right hemisphere stroke throughout different periods of recovery.

Methods/Procedures: Participants completed online surveys and a semi-structured phone interview. Analysis of the interviews revealed four major …

Investigating Predictive Relationships Between Speech-Language Pathology Graduate Students' Sense Of Classroom Community, Perceived Learning, And Perceived Anxiety., Emily B. Schantz

Electronic Theses and Dissertations

Mental health is an all-encompassing term that focuses on a person’s ability to achieve work-life balance inclusive of positive mental health and mental ill-health. Current trends suggest an overall increase in mental ill-health for undergraduate and graduate students. McMillan and Chavis’ sense of community theory provided the theoretical framework for this study. This study aimed to examine whether speech-language pathology graduate students’ sense of classroom community and perceived learning predict anxiety levels while controlling for demographic variables. Three-hundred-sixteen master’s level speech-language pathology students completed an online survey containing the Generalized Anxiety Disorder Questionnaire, Perceived Learning Scale, and Classroom Community Scale. …

Modeling Hrtf For Sound Localization In Normal Listeners And Bilateral Cochlear Implant Users, Douglas A. Miller

Electronic Theses and Dissertations

Mathematical models can be very useful for understanding complicated systems and for testing algorithms through simulation that would be difficult or expensive to implement. This dissertation presents a model that attempts to simulate the sound localization performance of persons using bilateral cochlear implants. The expectation is that this model could prove to be a useful tool in developing new signal processing algorithms for neural encoding strategies.

The head related transfer function (HRTF) is a critical component of this model, and in the ideal case, provides the base characteristics of head shadow, torso and pinna effects. This defines the temporal, intensity …

A Model For Electrical Communication Between Cochlear Implants And The Brain, Douglas A. Miller

Electronic Theses and Dissertations

In the last thirty years, cochlear implants have become an invaluable instrument in the treatment of severe-to-profound hearing impairment. An important aspect of research in the continued development of cochlear implants is the in vivo assessment of signal processing algorithms intended to improve perception of speech and other auditory signals. In trying to determine how closely cochlear implant recipients process sound relative to the processing done by a normal auditory system, various assessment techniques have been applied. The most common technique has been measurement of auditory evoked potentials (AEPs), which involves the recording of neural responses to auditory stimulation. Depending …

Temperament And Early Communication In Premature Children., Nina King

Electronic Theses and Dissertations

Premature children are at greater risk for developing communication delays than full-term children, although it is not inevitable. Recent research links specific temperament characteristics to early language development. Thus, temperament may provide a way to identify premature children who are at increased risk. The first purpose of this study was to determine if temperament characteristics of premature children are the same as full-term children when measured by the Infant Behavior Questionnaire-Revised. The second purpose was to determine if temperament and language acquisition, as measured by the MacArthur Communicative Development Inventory: Words and Gestures, are linked in premature infants …

Early Speech And Language Development: A Comparison Of Typically Developing Children To Children With Cleft Palate., Holly Jannice Mcgahey

Electronic Theses and Dissertations

Previous research has shown that parent implemented intervention is effective in increasing the speech and language development of children with cleft lip and palate. To further determine the efficacy of this intervention, this study compared the speech and language development of children with CLP, who received parent implemented intervention, with a group of younger, typically developing children, matched for vocabulary size. This study also evaluated the language differences between the mothers of both groups of children. Speech and language assessments were administered to the typically developing children and their mothers at two times to mirror the time of assessment for …

The Effects Of A Multimodality Approach On Sentence Production Using Response Elaboration Training With A Reading Component On Aphasic Patients., Sara E. Mccarthy

Electronic Theses and Dissertations

The effects of a multimodality treatment were investigated using a single subject experimental design across behaviors in two patients with different severity levels of Broca's aphasia. We hypothesized that Response Elaboration Training and an oral reading task would improve accuracy of sentence production, information content, and mean length of utterance. Results indicated that this treatment approach elicited significant improvement in the accuracy of sentence production and information content in the participant with very mild Broca's aphasia. Furthermore, the participant with severe Broca's aphasia demonstrated a very significant improvement in information content and mean length of utterance. The improvements support the …

An Enhanced Dialogic Reading Approach To Facilitate Typically Developing Pre-School Children's Emergent Literacy Skills., Sheri E. Davis

The study consisted of 8 preschoolers (5 DR+CL, 3 DR). The classroom PA training was conducted 3 times a week for 5 weeks for 20 minutes, using play-based activities. The DR training programs were held once a week for 5 weeks for 90 minutes teaching strategies that could be used in the home environment. …

The Type And Frequency Of Morphosyntax Errors In Children's Narratives., Jennifer Lynn Lockhart

Electronic Theses and Dissertations

A subsample of 478 children who originally participated in a larger study (Tomblin et al., 1997) was examined for type and frequency of morphological noun and verb errors in oral and written narratives in 2^nd and 4^th grade. Each child represented one of four groups: Typical Language, Specific Language Impairment, Nonspecific Language Impairment, and Low Nonverbal IQ. Three MANOVA's and post-hoc comparisons were used to test three predictions: (1) children will have more difficulty with verb than noun morphology; (2) children will make more errors in the written than the spoken narratives; and (3) children whose language impairments …

The Description And Comparison Of Feature Retention Patterns For Children With Phonological Impairment Developmental Apraxia Of Speech And Typically Developing Children., Amanda N. Lambert

Electronic Theses and Dissertations

The purpose of the present study was to compare feature retention patterns between children developing speech typically (TD) and children with phonological impairment (PI) and to discuss these findings in terms of characteristics, severity, and implication for the identification of developmental apraxia of speech (DAS). A second purpose was to determine if a relationship exists between phonological knowledge and feature retention.

This study consisted of a PI group and a TD group of children, ages four to six. A 245-item speech sample was collected from each subject. Feature retention percentages as well as percent correct underlying representation (PCUR) were calculated …
