Backward Masking With Simultaneous Early, Middle And Late Evoked Potentials, Silas Smith

Graduate Student Theses, Dissertations, & Professional Papers

Auditory processing disorders (APDs) affect a diverse range of people. These types of disorders impair auditory function, despite the outer, middle and inner ear maintaining proper function and health. APD is not necessarily related to auditory thresholds. When people with APD have difficulty discriminating sounds in connected speech, it may be due in part to an effect called Backward Masking (BM). Masking occurs when one stimulus inhibits another, which can lead to a variety of impairments. The neural locus of APDs is for the most part unknown, including the specific conditions which cause BM. A better understanding of these processes …

Significance Of The Feminization Of Male Eating Disorders, Rachel Rothman

Undergraduate Research Symposium Posters

Today, many individuals develop eating disorders; however, eating disorders are typically associated with women. In this paper, I declare that male eating disorders are stigmatized due to the feminization of eating disorders. I explain why this stigma exists and how this bias inhibits professionals from conducting objective research on male eating disorders and diagnosing them correctly. I illustrate how the stigma prevents men from recognizing their own unhealthy behaviors and can deter individuals from recognizing eating disorder-related behaviors in other men. Throughout the essay, I provide my own analysis regarding how to combat the stigmatization of eating disorders. By writing …

Receptive And Expressive Single Word Vocabulary Errors Of Preschool Children With Developmental Disabilities, Juliana L. Hirn

Honors Undergraduate Theses

Vocabulary growth during the preschool years is critical for language development. Preschool children with developmental disabilities often have more difficulty with learning and developing language, therefore making more errors in vocabulary. It is important to recognize what type of errors children are demonstrating, especially as it relates to receptive and expressive language abilities. This study explores the error patterns preschool children with developmental disabilities make during receptive and expressive single word vocabulary tests. A secondary analysis of preexisting data was conducted from a sample of 68 preschool children with developmental disabilities ranging in severity. Based on a coding system developed …

Pituitary Gland Functional Connectivity And Bmi, E. Paige Rucker

Honors Theses

This study examined the link between pituitary gland functional connectivity and BMI. The pituitary gland plays various roles in the body through the secretion of hormones, but its direct role in development of obesity and BMI management is unknown. Resting state functional Magnetic Resonance Imaging (rsfMRI) brain data of individuals with diverse BMIs were analyzed by voxel-wise analysis to determine the functional connectivities of the pituitary gland to other regions of the brain. A significant negative correlation was found between BMI and pituitary gland functional connectivity in eleven different brain regions. These regions include the posterior thalamus, lingual gyrus, precuneus, …

Promotion Of Early Pediatric Hearing Detection Through Patient Navigation, Matthew L. Bush

Theses and Dissertations--Clinical and Translational Science

Congenital hearing loss is the most common neonatal sensory disorder and it is crucial to diagnose hearing loss as soon as possible after birth in order to facilitate rapid treatment. Universal standards of infant hearing healthcare dictate that infant hearing screening should be completed by one month of age and abnormal screening tests should be followed with definitive audiological testing by three months of age. Obtaining diagnostic testing can be complicated by limited access to care in rural areas, breakdowns in communication, lack of parental support, and poor coordination of care. There is no established method to address appointment non-adherence …

Theses and Dissertations--Communication Sciences and Disorders

The primary purpose of this investigation was to explore the effects of varying degrees of vocal tract semi-occlusion in Vocal Function Exercises (VFEs) on attainment of pre- established maximum phonation time (MPT) goals in individuals between the ages of 18 and 45 with normal voice. Individuals were randomized into three experimental groups: the traditional VFE with a semi-occluded vocal tract (SOVT), modified /o/ with partial occlusion, and modified /a/ without significant occlusion. For six weeks, the participants completed the four exercises two times each, twice daily on corresponding vocal tract postures assigned by group. Results indicated significant change in percent …

Inter-Rater Reliability Of Diagnostic Language Testing Administered Via Telepractice, Sarah E. Adams

Theses and Dissertations--Communication Sciences and Disorders

Federal law mandates children with language disorders receive free and appropriate intervention. Diagnosis is the first step in the intervention continuum; however, children in rural America are underserved due to personnel shortages. Limited studies have demonstrated the reliability of language testing conducted via telepractice. Further research examining the reliability of language tests administered via telepractice is necessary. The purpose of this study was to assess inter-rater reliability of three language tests administered via telepractice.

Faculty Publications

The purpose of the present paper was to examine the social validity of telepractice as a service delivery model for Spanish-speaking families of English learners. Quantitative survey methodology was employed to examine 79 caregivers' opinions regarding telepractice and to obtain background information about participants' home environments. Findings revealed that approximately 46% of the participant sample reported being interested in their children receiving services via telepractice. Caregivers reported limited familiarity with telepractice as an option, but were likely to express interest if their child had an identified speech or language disorder or if they were interested in increased access to Spanish …

Phonetic Complexity Affects Children’S Mandarin Tone Production Accuracy In Disyllabic Words: A Perceptual Study, Puisan Wong, Winifred Strange

Publications and Research

This is the first study to examine the effect of phonetic contexts on children’s lexical tone production. Mandarin tones in disyllabic words produced by forty-four 2- to 6-year-old children and twelve mothers were low-pass filtered to eliminate lexical information. Native Mandarin speaking adults categorized the tones based on the pitch information in the filtered stimuli. All mothers’ tones were categorized with ceiling accuracy. Counter to the findings in most previous studies on children’s tone acquisition and the prevailing assumption in models of speech development that children acquire suprasegmental features much earlier than segmental features, this study found that children as …

Validating The Accuracy Of A Language Screening Instrument In Identifying Preschool Children In El Paso, Texas, Roxana Stubbemann

Open Access Theses & Dissertations

Background: Effective screeners are time and cost effective and may be an efficient indicator of whether a child needs further in-depth assessment. Surveyed Speech-Language Pathologists in the El Paso, TX region report using informal screening tools such as observational measures and checklists due to the lack of adequate standardized tools that suit the needs of bilingual children, which occupy a majority of their caseloads (Curtis, Summers, Smith, & Stubbemann, 2016). Many language-screening instruments are not psychometrically sound for culturally and linguistically diverse (CLD) populations and limited research exists on the accuracy of these tools.

Purpose: The purpose of this study …

Singing Portuguese Nasal Vowels: Practical Strategies For Managing Nasality In Brazilian Art Songs, André Campelo

Theses and Dissertations--Music

The articulation of Portuguese nasalized vowels poses some articulatory problems accompanied by negative acoustic effects for the performance of Brazilian art songs. The main objective was to find strategies that permit the singer to conciliate an idiomatic pronunciation of these vowels with a well-balanced resonance, a desirable quality in classical singing. In order to devise these strategies, the author examined sources dealing with nasalized vowels from varied perspectives: acoustic properties of vowel nasalization, phonetic and phonological aspects ofBrazilian Portuguese (BP), historical views on nasality in singing, and recent vocal pedagogy research. In addition to the overall loss of sonority, the …

Action Understanding Via Mirror Neuron Systems: A Proposed Model For The Science And Treatment Of Stuttering, Madison Jones

Honors Theses

Persistent developmental stuttering is generally considered to be a speech disorder characterized by repetitions, prolongations and postural fixations, and is relatively resistant to therapy. While mainstream stuttering therapy continues to rely on behavioral speech targets, recent research suggests that mirror neuron systems can be activated to temporarily induce natural sounding fluent speech in those who stutter via exposure to second speech signals. Despite the prevalence of speech-motor based stuttering treatments, a unified account of how and why fluency is enhanced through endogenous methods remains elusive. The purpose of these two exploratory studies is to further test the validity of the …

Effects Of Laryngeal Activity On Articulation, Christopher Dromey, Katherine M. Black

Faculty Publications

Abstract—This study examined the effects of three speech conditions (voiced, whispered, and mouthed) on global average measures of articulatory movement during sentence production. Participants were 20 adults (ten males and ten females) with no history of speech, language, or hearing disorders. They produced six target utterances in the three speaking conditions. Movements of the following articulators were recorded with an electromagnetic articulograph: Mid tongue, front of tongue, jaw, lower lip, and upper lip. The kinematic metrics were averages derived from movement strokes defined by minima in the speed record of each articulator. These measures revealed a number of significant changes …

This study examined the nature and severity of voice disorders in patients with SGS before and after a revised cricotracheal resection (CTR) procedure designed to minimize adverse effects on voice function. Method: Eleven women with idiopathic SGS provided presurgical and postsurgical audio recordings. Voice Handicap Index (VHI) scores were also collected. Cepstral, signal-to-noise, periodicity, and fundamental frequency (F0) analyses wereundertaken for connected speech and sustained vowel samples. Listeners made auditory-perceptual ratings of overall qualityand monotonicity.Results: Paired samples statistical analyses revealed that …

Effects Of Speech Intensity On Acoustic And Kinematic Articulatory Working Space, Christopher Dromey, Panika Palmer, Jason Whitfield

Faculty Publications

Acoustic measures calculated from the formant frequencies of corner vowels, such as the vowel space areas of triangles or quadrilaterals, have often been used as a window into articulatory function. Other measures, such as the formant centralization ratio (Sapir, Ramig, Spielman, & Fox, 2010), have been suggested as more sensitive alternatives. The purpose of this study was to compare changes in acoustic and kinematic measures of articulation across soft, comfortable, and loud speech conditions using both corner vowel-based and sentence level metrics. There were 19 participants, 9 male and 10 female, with ages ranging from 20 to 34 years. Each …

Incorporating Spanish Language Instruction Into Health Sciences Programs In A Hispanic-Serving Institution, Connie Summers, Vannesa Mueller, Celia Pechak, Jeri J. Sias

Faculty Publications

Patient-provider language discordance is a growing problem in health care among Spanish-speaking patients. To produce graduates capable of linguistically competent care, three university programs are incorporating Spanish language instruction into their curricula (pharmacy, physical therapy, and speech-language pathology). We review these three models of Spanish language training and summarize the lessons learned to date. Differences in the training models reflect fundamental differences regarding the use of spoken language in the disciplines.

The clinical fellowship (CF) is completed by speech-language pathologists (SLPs) after graduating with a master’s degree. The clinical fellow is supervised by a mentoring SLP who meets the qualifications set forth by the American Speech-Language-Hearing Association (ASHA). The current study focused on differences and similarities in expectations during the CF by the mentoring SLP and clinical fellow. Participants were asked about knowledge and skills for which clinical fellows are evaluated at the end of the CF in the areas of assessment and treatment. Clinical fellows wanted more help with assessment and less assistance with treatment. Mentoring SLPs felt assistance was …

Vocal Fry Use In Adult Female Speakers Exposed To Two Languages, Todd A. Gibson, Connie Summers, Sydney Walls

Faculty Publications

Summary: Objective. Several studies have identified the widespread use of vocal fry among American women. Popular explanations for this phenomenon appeal to sociolinguistic purposes that likely take significant time for second language users to learn. The objective of this study was to determine if mere exposure to this vocal register, as opposed to nuanced sociolinguistic motivations, might explain its widespread use. Study Design. This study used multigroup within- and between-subjects design. Methods. Fifty-eight women from one of three language background groups (functionally monolingual in English, functionally monolingual in Spanish, and Spanish-English bilinguals) living in El Paso, Texas, repeated a list …

Language Of Intervention In Bilingual Children With Autism Spectrum Disorders, Connie Summers, Vanessa Smith, Vannesa Mueller, Victoria Alexander, Amelie Muzza

Faculty Publications

Selecting the appropriate language of intervention for bilingual children with language impairment is difficult, especially for bilingual children with autism spectrum disorders (ASD) as their families are often encouraged by professionals to select one language only for communication. The limited evidence supports the use of bilingual language interventions when working with bilingual children with ASD. The current study sought to expand this limited work by presenting preliminary data of the effects of a bilingual and monolingual treatment condition on the language skills of two bilingual children with ASD (ages 3 and 5) using an alternating treatment, single-subject design. The two …

Faculty Publications

Objective: Auditory neuropathy spectrum disorder (ANSD) affects approximately 5–15% of children with sensorineural hearing loss (SNHL). ANSD is characterized by the presence of otoacoustic emissions (OAE) and an absent or abnormal auditory brainstem response (ABR). The purpose of this study was to investigate the prognostic value of slow-rate ABR in predicting the auditory cortical development and auditory speech perception outcomes in case studies of children with ANSD. Design: ABR waveform characteristics were collected at slow stimulation rates (5.1 clicks/second) and a fast stimulation rates (>11–31.1 clicks/second, rates typically used in a clinical setting) in three case reports of children …

Structural Covariance Of Sensory Networks, The Cerebellum, And Amygdala In Autism Spectrum Disorder, Garrett Cardon, Susan Hepburn, Donald C. Rojas

Faculty Publications

Sensory dysfunction is a core symptom of autism spectrum disorder (ASD), and abnormalities with sensory responsivity and processing can be extremely debilitating to ASD patients and their families. However, relatively little is known about the underlying neuroanatomical and neurophysiological factors that lead to sensory abnormalities in ASD. Investigation into these aspects of ASD could lead to significant advancements in our general knowledge about ASD, as well as provide targets for treatment and inform diagnostic procedures. Thus, the current study aimed to measure the covariation of volumes of brain structures (i.e., structural magnetic resonance imaging) that may be involved in abnormal …

The Use Of Code-Switching In Bilingual Children With Autism Spectrum Disorder, Monica Yolanda Ponce-Lawler

Open Access Theses & Dissertations

Abstract

Background: Code-switching may be seen as a weakness in the eyes of many who do not truly

understand bilingualism. Several professionals consider code-switching to be a compensatory

strategy, however other professionals perceive code-switching as a functionally motivating behavior

(Chung, 2006). Whether is it consciously or subconsciously that a child code-switches, there is

limited research on when bilingual children with Autism Spectrum Disorder (ASD) are likely to

code-switch as well as what patterns they utilize when they code-switch.

Purpose: To grow the limited research on the use of code-switching in bilingual children with ASD.

Introduce and compare two language treatments; …

However, research suggests that there are several factors that influence screening, referral, and diagnostic practices. This study aimed to analyze key themes that arose when parents of children with disabilities and pediatric healthcare providers discussed screening, referral, and diagnostic practices for children in El Paso, a medically underserved community. Researchers conducted a 2- phase study that employed both quantitative and qualitative methodology. Results …

K-5 Educators' Perceptions Of The Role Of Speech Language Pathologists, Dr. Karmon D. Hatcher

Walden Dissertations and Doctoral Studies

Rarely is a school-based speech language pathologist (SLP) thought of as an active contributor to the achievement of students or to the learning community in general. Researchers have found benefits for students when members of the learning community collaborate, and the SLP should be a part of this community collaboration. This qualitative case study examined elementary school teachers', administrators', and reading specialists' perspectives related to knowledge of and the inclusion of the SLP in the learning community at a local elementary school in central Georgia. Schon's theory of reflective practice and Coleman's theory of social capital provided the conceptual framework. …

Examining The Reversal Of Vocal Fold Dehydration Using Aerosolized Saline In An Excised Larynx Model, Maya Elena Stevens

Theses and Dissertations

Previous studies have found vocal fold hydration to be crucial for healthy function of the vocal mechanism. Surface tissue hydration facilitates efficient vocal fold oscillation. The composition of vocal fold surface fluid includes protective water and mucus layers, similar to the fluid that covers the mucosa and epithelia of the upper airway. Laryngeal dehydration has been linked to several factors such as mouth breathing, obstructive sleep apnea, dry air exposure, upper airway hypersensitivity, and certain diseases or behavioral voice use factors. Laryngeal dehydration affects phonation threshold pressure (PTP) and phonation threshold flow (PTF), defined as the pressure and flow observed …

Medication Use In Adults Who Stutter, Hailey Renee Guillot

LSU Master's Theses

Previous studies have associated stuttering with increased levels of self-stigma. Prior research has shown that high levels of self-stigma may relate to increased medication usage. Therefore, in the present study, the authors sought to determine an association between levels of self-stigma and medication usage among adults who stutter. Results suggest that although there is not a significant difference for lifetime medication use between AWS versus AWNS, the self-imposed stigma by AWS could predict the likelihood of medication use. Findings provide insight into additional pharmacological factors to consider during clinical intervention, and highlight the importance of stigmatized beliefs when addressing the …
