Hearing Loss: Investigating The Comfort, Confidence, Knowledge, And Preparedness Of Kentucky School-Based Speech-Language Pathologists., Amanda Matsumoto

Electronic Theses and Dissertations

Due to advances in technology, the number of users with hearing devices have increased. These users are often mainstreamed into classrooms with typical hearing peers. However, even with these devices, speech and language impairments may still persist. This study was conducted to analyze school-based speech-language pathologists’ (SLP) comfort, confidence, knowledge, and preparedness in treating students with hearing loss in Kentucky schools. 48 SLPs practicing in all levels of school including elementary, middle, and high, completed an anonymous online survey through the Qualtrics^® platform. Responses were received from SLPs representing 11 out of the 15 regions throughout Kentucky. Spearman’s rank …

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 …

Perceptions Of Guilt Of Individuals With A Visible Communication Disorder Versus An Invisible Communication Disorder, Zoe Hochberg

Honors Scholar Theses

This study explored how communication disorders may impact listeners’ perception of guilt. More specifically, it looked at how visible communication disorders (e.g., stuttering) and invisible communication disorders (e.g., high functioning autism) are judged by the general public. 51 adults (18-71 years) participated in the study which asked them to view video recordings of narrative samples produced by an individual who stuttered (PWS), an individual with high-functioning autism (PHFA), and an individual with no communication disorder (PNCD). Participants were not informed of the individuals’ communication abilities (PWS, PHFA, or PNCD), but were told that one of the individuals had committed a …

Factors Of Dysphagia In The Overdose Population Post Extubation., Renee Brown

Electronic Theses and Dissertations

Post-extubation dysphagia (PED) has been studied in depth in a variety of populations including elective heart surgeries, trauma, critical illness, traumatic brain injury, and those requiring mechanical ventilation, but has not been researched in the overdose population (OD). This study aims to research factors of PED in the OD population. A retrospective study was conducted and found 24 participants who fit the inclusionary requirements. Correlation statistics were run between age and duration of intubation, age or duration of intubation and gender, and between intubation duration, age, and scores on Penetration-Aspiration Scale (P/A) (thin by cup and thin by straw). The …

Development Of The Caregiver-Child Auditory Skills Tracking (Cast) Scale: A Pilot Study On Caregiver Implementation Via International Telepractice, Elizabeth Ocampo-Roman

Graduate Theses and Dissertations

Parent engagement is a key component during early language development for all children, but particularly for a child with hearing loss. Through the application of technology-based models of service delivery such as telehealth, researchers have found an increase in parent-child engagement during auditory-verbal therapy (AVT) sessions due to the physical absence of the provider and parents becoming the primary language facilitators. However, current measures of parent-child interactions do not have a coding system to monitor facilitation of auditory skills. This present study will discuss the development of the Caregiver-Child Auditory Skills Tracking (CAST) Scale to track progress of caregiver implementation …

Respiratory Differences In Spontaneous And Scripted Speech Among Bilingual Adults, Anna Irene Sagan

Honors Program Theses

This investigation explored respiratory differences between a speaker’s first language (L1) and second language (L2) during spontaneous and scripted speech in six adult bilingual speakers (two native bilingual speakers and four non-native bilingual speakers). Respiratory kinematic data using Respitrace respiratory inductance plethysmography and acoustic recordings were collected during five tasks: tidal breathing at rest, scripted speech in L1, spontaneous speech in L1, scripted speech in L2, and spontaneous speech in L2. Results indicated a significant interaction effect between proficiency and syllables produced during spontaneous speech, but no other significant differences were found among inspiratory/expiratory duration, task, proficiency or language. The …

Relation Between Linguistic Awareness Skills And Spelling In Adults: A Comparison Among Scoring Procedures, Victoria Henbest

Victoria S. Henbest Publications

Spelling is a skill that relies on an individual's linguistic awareness, the ability to overtly manipulate language. The ability to accurately spell is important for academic and career success into adulthood. The spelling skills of adults have received some attention in the literature, but there is limited information regarding which approach for analyzing adults' spelling is optimal for guiding instruction or intervention for those who struggle. Thus, we aimed to examine the concurrent validity of four different scoring methods for measuring adults' spellings (a dichotomous scoring method and three continuous methods) and to determine whether adults' linguistic awareness skills differentially …

Vocal Health Of Choral Singers From Kenya And The United States: Dysphonia And Vocal Fatigue In Relation To Musical Genres, Morgan Jolley Burburan

USF Tampa Graduate Theses and Dissertations

The purpose of this mixed-methods study was to investigate the vocal health of choral singers from Kenya and the United States and to determine whether genre (classical choral, traditional Kenya, and Contemporary Commercial Music [CCM]) had any impact on healthy vocal production, particularly as it related to vocal fatigue. Participants were adult singers (N = 94) in two semi-professional choirs, the Nairobi Chamber Chorus (NCC) from Kenya (n = 25) and the Festival Singers of Florida (FSOF) from the United States (n = 69). Singers’ perceived overall vocal health was measured using multiparametric clinical self-reporting instruments and acoustical assessment. Singers’ …

Self-Disclosure Of Stuttering To Various Social Referent Groups And Its Relationships With Psychological Distress, Katrina Rourke

Honors Theses

Purpose: Research has shown that there are benefits associated with verbal disclosure of stuttering. However, most of the existing literature on stuttering disclosure has focused on how it affects listener perceptions of people who stutter, and little is known about speaker-focused outcomes of verbal stuttering disclosure. The purpose of the current study was to investigate who people who stutter verbally disclose to (e.g. friends, co-workers, neighbors) and if relationships between extent of disclosure and distress vary depending on the confidant’s social referent group. The seven social referent groups of focus were family, friends, romantic partners, people in the workplace, healthcare …

Acoustic Changes During Passage Reading In Speakers With Parkinson's Disease, Kimberly C. Grubbs

LSU Master's Theses

Purpose: The purpose of this study was to evaluate speech changes in Parkinson’s disease (PD) while reading a passage, using both local (i.e., segment level) and global (i.e., utterance level) acoustic measures.

Methods: 20 speakers participated in the study (10 PD, 10 neurologically healthy controls). The speakers were asked to read The Caterpillar passage in a conversational mode. A total of five acoustic measures were included (local: vowel duration, Euclidean distance between corner vowels and schwa; global: articulation rate, F0/intensity range). These acoustic measures were compared between two sentences located in the two positions within the paragraph, initial and final. …

The Relationship Between Working Memory, Procedural Learning, And Declarative Memory In Children With Specific Language Impairment, Allison Grace Herring

LSU Master's Theses

Background: Children with specific language impairment (SLI) have recently been suggested to have subclinical deficits in executive function skills. The current study seeks to better understand these deficits by exploring the role of nonverbal working memory in word learning and statistical learning in this population. Method: Participants included typically developing children along with children with SLI ranging from ages 8-12 years old. Word learning was assessed using a fast-mapping task, statistical learning was measured using a word-segmentation task, and nonverbal working memory was measured using an N-back task. Results: A significant difference was found between children’s segmentation accuracy scores. …

Brain Activation For Cochlear Implant Users: A Pilot Fnirs Study, Makayla Gill, Ceceli Bonitto, Bailey Heaton, Yingying Wang

UCARE: Research Products

Cochlear implants (CIs) have become a widespread device for individuals with severe-to-profound sensorineural hearing loss (SNHL) to regain hearing ability and improve quality of life. However, the brain needs to adapt to this bionic device and relearn the function of hearing, especially for speech sounds. Because the auditory inputs through a CI are not the same as those heard by individuals with typical hearing, aural rehabilitation takes time. The goal of this study is to examine neural bases of speech perception in adult CI users using functional near-infrared spectroscopy (fNIRS). Two adults with bilateral SNHL and CI(s) were fitted with …

A Literature Review Examining The Effects Of Bilingualism In Individuals Who Stutter, Cheyenne Hofmann

Honors College Theses

This thesis will analyze the current research involving the impact of bilingualism in individuals who stutter through a literature review. There is currently no known etiology of stuttering, however, there are multiple theories regarding the onset of stutter. This thesis will explore the Cerebral Dominance theory of stuttering and its applicability to neuroimaging and bilingualism. Furthermore, this thesis will determine the presence and extent of the impact of bilingualism on people who stutter. The cultural, gender, language and neurological influences on stuttering for those who are bilingual will also be examined. Through this analysis, the positive and negative impact of …

Speech Exemplar And Evaluation Database (Seed) For Clinical Training In Articulatory Phonetics And Speech Science, Marisha Speights Atkins, Dallin J. Bailey, Suzanne E. Boyce

Faculty Publications

One challenge faced by teachers of phonetics, speech science, and clinical speech disorders courses is providing meaningful instruction that closes the theory to practice gap. One barrier to providing this type of deep learning experience is the lack of publicly available examples of speech recordings that illustrate comparisons between typical and disordered speech production across a broad range of disorder populations. Data of this type exist, but are typically collected for specific research projects under narrowly written IRB protocols that do not allow for release of even de-identified speech recordings to other investigators or teachers. As a partial corrective to …

Acoustic Characteristics Of Word-Final American English Liquids Produced By L2 Adult Speakers, Judith A. Espinal

LSU Master's Theses

In this study, the acoustic differences between native English speakers’ (L1) and native-Korean speakers’ (L2) production of American English liquids /ɹ/, /l/ and /ɹl/ were examined among 14 Korean speakers and 13 English speakers. Temporal measures included (1) relative timing of maximum constriction and (2) duration of vocalic nuclei. Spectral measures included (1) Euclidean distance between /ɹ/ and /l/ and (2) frequency difference between F2 and F3. The results indicated a significant interaction between speaker group and phonetic stimuli. That is, L2 speakers produced a similar degree of constriction across semivowels, whereas L1 speakers produced varying degrees of F2-F3 constrictions …

Research To Practice- Implementing Sign-Infused Intervention As A Novice Clinician, Loren Stoller

LSU Master's Theses

Speech-Language Pathologists often infuse manual signs into oral language interventions for children with various communication disorders. The current study was designed to learn more about sign-infused language intervention by examining one novice clinician’s use of signs during oral language intervention with a child diagnosed as a late talker. The researcher was the clinician, and while a novice interventionist, she was proficient in American Sign Language (ASL) and had five years of experience using ASL with others. The child was 26 months of age at the start of the study, and data collection included three pre-intervention sessions, 12 intervention sessions, and …

Effects Of Speech Cues In French-Speaking Children With Dysarthria, Erika S. Levy, Gemma Moya-Galé, Younghwa Michelle Chang, Luca Campanelli, Andrea A. N. Macleod, Sergio Escorial, Christelle Maillart

Publications and Research

Background: Articulatory excursion and vocal intensity are reduced in many children with dysarthria due to cerebral palsy (CP), contributing to the children’s intelligibility deficits and negatively affecting their social participation. However, the effects of speech-treatment strategies for improving intelligibility in this population are understudied, especially for children who speak languages other than English. In a cueing study on English-speaking children with dysarthria, acoustic variables and intelligibility improved when the children were provided with cues aimed to increase articulatory excursion and vocal intensity. While French is among the top 20 most spoken languages in the world, dysarthria and its management in …

Investigating The Modulatory Effect Of Expectations On Memory Retrieval During Sentence Comprehension, Luca Campanelli

Dissertations, Theses, and Capstone Projects

Memory retrieval and probabilistic expectations are recognized factors in sentence comprehension that capture two different critical aspects of processing difficulty: the cost of retrieving and integrating previously processed elements with the new input words and the cost of incorrect predictions about upcoming words or structures in a sentence. Although these two factors have independently received substantial support from the extant literature, how they interact remains poorly understood. This study investigated memory retrieval, more specifically retrieval interference, and lexical-semantic expectations in three reading experiments, pitting these factors against each other to observe how they interact. Overall, results showed that retrieving and …

Speech Motor Control In Younger And Older Adults: The Effect Of Age And Individual Differences On Speech Error Production, Katherine M. Dawson

Dissertations, Theses, and Capstone Projects

This dissertation investigates three main issues in speech motor control, all of which are explored through the lens of speech error production. The speech error elicitation task used is the alternating onset, identical coda (e.g. ‘top cop’) paradigm, which in this incarnation is executed in time to a rate-increasing metronome. The first experimental chapter asks why some speakers may be more prone to the production of speech errors than others, from an individual differences perspective. A number of speaker attributes are taken into account, including age (older and younger adults), performance on a subset of cognitive tasks, as well as …
