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 …

Communicative Function And Diversity In Provider, Deaf And Hard-Of-Hearing Child, And Caregiver Speech During Telepractice, Rebekah G. O'Bryan, Jessica M. Julian, Maria V. Kondaurova

Undergraduate Arts and Research Showcase

How does the use of telepractice during speech language therapy affect the communicative function and communicative diversity of provider, deaf and hard-of-hearing (DHH) pediatric patient, and caregiver speech? This study examined communicative functions and diversity in the provider, DHH children with cochlear implants (n = 7, mean age = 4.9 years, range = 3.5-6.75 years), and caregiver utterances during one 30-minute in-person and one sequential tele session, order counterbalanced. To measure communicative function, each utterance was classified into 16 mutually exclusive categories for the child and into 15 categories for the adults. Communicative diversity was calculated as the number of …

A Patient-Centered Ethnographic Interview And Measurement Of Intelligibility In Spastic-Ataxic Dysarthria For People With Multiple Sclerosis, Courtney Marie Leppek

Wayne State University Theses

Multiple sclerosis (MS) produces neurological impairments that are variable in duration and severity, and that are unique to each case of MS. In addition to variability of symptoms, the length of the MS diagnostic process often affects quality of life. In this mixed qualitative and quantitative study, we used ethnographic interviews to investigate the underlying thoughts and feelings of two very different individuals with MS and Spastic-Ataxic Dysarthria. The results contribute to the understanding of MS as a multi-faceted condition that has implications that are both internal and external to the person with MS. Further, the results reflect the clinical …

School-Based Speech-Language Pathologist Collaborative Practice: A Literature Review, Kaija R. Elenko

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Background: School-based speech language pathologists (SLPs) are increasing collaborative engagement with educators and other professionals in school settings. Collaborative practice in the general education classroom increased student’s awareness of literacy concepts. The push-in model of service delivery reached students with varied levels of literacy understanding. There is insufficient empirical evidence regarding school-based interprofessional practice (IPP) available to clinicians. Systemic reviews provide a model for educators and SLPs to follow; many professionals hesitate to engage in IPP because there is a deficiency in evidence of success.

Aims: Investigation of the necessary components for successful IPP and the impacts of collaboration on …

Using Transcranial Direct Current Stimulation To Improve Naming Ability In Post-Stroke Aphasia: Evaluating Evidence And Optimizing Outcomes, Mohammed Alharbi

Theses and Dissertations--Rehabilitation Sciences

Introduction. Aphasia is a devastating acquired language disorder that affects about one third of stroke survivors. Aphasia can severely affect quality of life and can be associated with economic burdens due to the need for long-term communication rehabilitation. Traditional aphasia therapies are known to be effective; however, progress is often slow and limited in severe cases – full restoration of communication abilities is rarely achieved. Thus, there is a critical need for therapeutic solutions that can reduce the associated burden of aphasia. Transcranial direct current stimulation (tDCS) is a non-invasive and inexpensive neuromodulation technique that has the potential to boost …

A Case Study On Accessible Reading With Deaf Children, Jody H. Cripps, Samuel J. Supalla, Laura A. Blackburn

Communication Disorders & Special Education Faculty Publications

The concept of accessible reading for deaf students is new and worthy of exploration. In the face of the reading difficulties often experienced by deaf students, the lack of a specialized reading methodology that works for them must be addressed. Central to the paper is a research case study undertaken with two young deaf students, proficient in American Sign Language (ASL) and learning to read. The students participated in a tutorial with a tutor knowledgeable in a specialized reading methodology called ASL Gloss. The participating students demonstrated progress in reading skills over time. Two reading measures were adapted from English …

Impact Of Nicu Design On Feeding-Related Outcomes In Preterm Infants, Emma Kate Calvert

Theses and Dissertations--Communication Sciences and Disorders

Many NICUs around the country are moving away from traditional open-bay designs in favor of single-family rooms (SFRs) as more is understood about the impact of the sensory environment on neurodevelopment in preterm infants. SFRs house one infant and their family for the length of the infant’s stay and are associated with improvements in numerous outcomes, including increased milk intake and weight gain and earlier transition to enteral feeding. Oral feeding remains a critical requirement for NICU discharge; however, the impact of NICU design on feeding outcomes remains unknown.

The purpose of this study was to compare feeding outcomes between …
