Tagalog And English Core Communication Boards For Tagalog-English Bilingual Children In The Philippines, Vianca A. Ocampo

Graduate Research Theses & Dissertations

A large proportion of children who use augmentative and alternative communication (AAC) devices to communicate are bilingual. Although many AAC devices allow access to each of the bilinguals’ languages, the devices are designed in such a way that access is limited to a single language at a time. Further, most devices contain translated vocabulary from English into the bilinguals’ other language. This study aimed to fill this gap by identifying core vocabulary words from narrative language samples of 4-year-old bilingual children to create ecologically valid communication boards. The language samples were analyzed to obtain the most frequently and commonly produced …

Investigating The Quality Of Life For Children With Autism Spectrum Disorder Scale Using Rasch Methodology, Laura C. Chezan, Jin Liu, Ruiqin Gao, Erik Drasgow

Communication Disorders & Special Education Faculty Publications

Our purpose in this study was to provide additional psychometric evidence of the Quality of Life for Children with Autism Spectrum Disorder (QOLASD-C) scale. We used Rasch modeling to investigate the QOLASD-C functioning, the characteristics of the items comprising the scale, and the item functioning across subgroups of children with ASD based on gender and race/ethnicity. Results showed that QOLASD-C was unidimensional, met the local independence assumption, and measured quality of life (QOL). The items showed excellent fit to the model and good discriminating ability between low and high QOL. Most items showed a moderate difficulty level. No differential item …

Parent-Child Interaction Therapy For Children With Disruptive Behaviors And Autism: A Randomized Clinical Trial, Korrie Allen, John Harrington, Lauren B. Quetsch, Joshua Masse, Cathy Cooke, James F. Paulson

Psychology Faculty Publications

A relatively large number of children with autism spectrum disorder (ASD) exhibit disruptive behavioral problems. While accumulating data have shown behavioral parent training programs to be efficacious in reducing disruptive behaviors for this population, there is a dearth of literature examining the impact of such programs across the range of ASD severity. To evaluate the effectiveness of Parent–Child Interaction Therapy (PCIT), an evidence-based treatment for children with problem behaviors and their families, in reducing disruptive behaviors among children (4–10 years) with ASD (without intellectual disabilities). Fifty-five children (85.5% male, 7.15 years; SD 1.72) were enrolled from pediatric offices and educational …

Enhancing Nonverbal Communication Through Virtual Human Technology: Protocol For A Mixed Methods Study, Analay Perez, Michael D. Fetters, John W. Creswell, Mark Scerbo, Frederick W. Kron, Richard Gonzalez, Lawrence An, Masahito Jimbo, Predrag Klasnja, Timothy C. Guetterman

Psychology Faculty Publications

Background: Communication is a critical component of the patient-provider relationship; however, limited research exists on the role of nonverbal communication. Virtual human training is an informatics-based educational strategy that offers various benefits in communication skill training directed at providers. Recent informatics-based interventions aimed at improving communication have mainly focused on verbal communication, yet research is needed to better understand how virtual humans can improve verbal and nonverbal communication and further elucidate the patient-provider dyad.

Objective: The purpose of this study is to enhance a conceptual model that incorporates technology to examine verbal and nonverbal components of communication and develop a …

Effect Of Nodule Size And Stiffness On Phonation Threshold And Collision Pressures In A Synthetic Hemilaryngeal Vocal Fold Model, Mohsen Motie-Shirazi, Matías Zañartu, Sean D Peterson, Daryush D Mehta, Robert E Hillman, Byron D Erath

Faculty, Staff and Student Publications

Synthetic vocal fold (VF) replicas were used to explore the role of nodule size and stiffness on kinematic, aerodynamic, and acoustic measures of voiced speech production. Emphasis was placed on determining how changes in collision pressure may contribute to the development of phonotrauma. This was performed by adding spherical beads with different sizes and moduli of elasticity at the middle of the medial surface of synthetic silicone VF models, representing nodules of varying size and stiffness. The VF models were incorporated into a hemilaryngeal flow facility. For each case, self-sustained oscillations were investigated at the phonation threshold pressure. It was …

Transition Class: A Bridge From Early Intervention To Early Childhood Special Education, Jamie Mahurin-Smith, Ciera M. Lorio

Faculty Publications – Communication Sciences and Disorders

Transitions are widely acknowledged to present challenges for young children with special needs. In the US system, the transition from early intervention (EI; services for children aged 0–3) to early childhood special education services (ECSE; services for preschool children) is a process known to cause uncertainty and anxiety for families. This paper describes a transition class offered by a midwestern US EI agency; children receiving EI services are eligible to participate beginning at age 2;6. Agency personnel chart the children’s progress each week. For this study, researchers reviewed de-identified weekly progress reports for the 40 transition class participants who attended …

Impact Of Accent On Receptive Language Assessments For Bilingual Children, Katherine Stariknok

Honors Theses and Capstones

Language assessments are used to screen and diagnose children with language disorders. Many speech-language pathologists (SLP) practicing in Spanish in the United States do not speak Spanish as their first language, so they are administering these assessments in accented speech. This study aims to find what effect an SLP’s accent will have on a bilingual child’s language assessment. Initial findings show that participants were largely able to understand words in the L2 accent, with most of the errors due to several repeating consonantal features (i.e., voicing alone; place and manner of articulation). The broader impact of this work is to …

Assessing Parental Conversational Overlap In A Museum Setting And Its Correlation With Child Language Skills, Madison Gould

Honors Theses and Capstones

Research has identified the importance of quality interactions with parents, caregivers, and peers in the promotion of language acquisition. We question how certain aspects of parental language, primarily repetition, expansion, and extension, correlate with child language skills. There is limited research available regarding the impact of conversational overlap on a child’s language development at a singular time point, with most studies being longitudinal, especially when assessing conversations between children and their caregivers in different settings, such as a museum exhibit. Our findings suggest that children need less parental recasting as they age and as their language skills are bolstered.

Language Development And Poverty: Considerations And Applications For Speech-Language Pathologists, Samantha Lynn Ehler

Honors Program Theses

Economics is one vital variable that can support or hinder the successful development and acquisition of language. A large body of research has shown that conditions of poverty often negatively impact a child’s language learning environment and brain development, resulting in poor language development and a high risk of speech and language disorders. Language development is a dynamic process that begins during the first years of life and is contingent on social interactions and safe predictable routines. A thorough examination of the relationship between familial financial standing and language development is the foundation for developing interventions that will minimize the …

Exposure, Adaptation And Expectations: How They Affect Perception Of Foreign Accented Speech, Isabella Huddleston

Honors Program Theses

Understanding accented speech is becoming more and more prevalent in today’s society. The world is connected through technology allowing us to reach further than we ever have before. One challenge this presents is the necessity to communicate across languages. Even if an individual has learned another language proficiently, the speech they produce is influenced by their native language resulting in foreign accented speech (FAS). There now exists the need for understanding how FAS affects speech perception and uncovering ways to improve communication situations between native and nonnative communication partners.

The Effects Of Inspiratory Muscle Training On Exercise-Induced Laryngeal Obstruction In Young Adults, Allison Lyman

Murray State Theses and Dissertations

Exercise-induced laryngeal obstruction (EILO) is a condition that results from abnormal vocal fold adduction upon inspiration (Abdel-Hamid, 2018). Symptoms of this ailment include dyspnea, choking sensations, an audible stridor, and/or coughing during physical exertion (Marcinow et al., 2014). These symptoms affect an individual’s ability to breathe adequately during exercise. A review of current literature suggests that there are a variety of interventions that can be used to reduce perceived dyspnea in individuals who suffer from EILO. One such intervention is known as inspiratory muscle training (IMT), which works to reduce dyspnea by strengthening the primary muscle of inspiration: the posterior …

Acoustic-To-Articulatory Speech Inversion Features For Mispronunciation Detection Of/ɹ/In Child Speech Sound Disorders, Nina R. Benway, Yashish M. Siriwardena, Jonathan L. Preston, Elaine Hitchcock, Tara Mcallister, Carol Espy-Wilson

Department of Communication Sciences and Disorders Faculty Scholarship and Creative Works

Acoustic-to-articulatory speech inversion could enhance automated clinical mispronunciation detection to provide detailed articulatory feedback unattainable by formant-based mispronunciation detection algorithms; however, it is unclear the extent to which a speech inversion system trained on adult speech performs in the context of (1) child and (2) clinical speech. In the absence of an articulatory dataset in children with rhotic speech sound disorders, we show that classifiers trained on tract variables from acoustic-to-articulatory speech inversion meet or exceed the performance of state-of-the-art features when predicting clinician judgment of rhoticity.

Revisiting The Rainbow: Culturally Responsive Updates To A Standard Clinical Resource, Angela M. Dietsch, Richard Mocarski, Debra A. Hope, Nathan Woodruff, Miechelle Mckelvey

Department of Special Education and Communication Disorders: Faculty Publications

Purpose

Cultural responsivity is essential for efficacious and affirming clinical relationships. This may be especially important with historically marginalized clients, such as transgender and gender-diverse (TGD) people seeking behaviorally based affirming communication services. We recommend modifications to standard tools for diagnostics and training that otherwise might undermine our efforts to create an inclusive and affirming environment.

Method

Modifications to the Rainbow Passage, a standardized paragraph utilized for eliciting speech samples in clinical settings, focused on nongendered terminology and the elimination of content with religious connotations.

Results

The recommended edits to the Rainbow Passage maintain similar length, cadence, and phonetic balance …

Brain Activity Associated With Taste Stimulation: A Mechanism For Neuroplastic Change?, Angela M. Dietsch, Ross M. Westemeyer, Douglas H. Schultz

Department of Special Education and Communication Disorders: Faculty Publications

Purpose: Neuroplasticity may be enhanced by increasing brain activation and bloodflow in neural regions relevant to the target behavior.We administered precisely formulated and dosed taste stimuli to determine whether the associated brain activity patterns included areas that underlie swallowing control.

Methods: Five taste stimuli (unflavored, sour, sweet-sour, lemon, and orange suspensions) were administered in timing-regulated and temperature-controlled 3 mL doses via a customized pump/tubing system to 21 healthy adults during functional magnetic resonance imaging (fMRI). Whole-brain analyses of fMRI data assessed main effects of taste stimulation as well as differential effects of taste profile.

Accent Services: Considering The Perspectives Of Non-Native Speakers Of English For A Culturally Affirming Practice, Kristopher Kilgallon

Master's Theses and Doctoral Dissertations

Accent “modification” is a type of service offered by speech-language pathologists (SLPs) that is intended to, among other things, help speakers improve their intelligibility in a target second language. This area of practice has been, and continues to be, a controversial topic amongst scholars and practitioners. To explore and understand the perspectives of non-native speakers of English regarding their participation in accent services, the present study employed a qualitative research design using individual, semi-structured interviews. Ten adult non-native speakers of English (female: n = 7; male: n = 3), with ages between 28 and 47 years old (M = …

The Impact Of Bowl Feeding On Infant Muscle Activity And Kinematics - An Executive Summary, Kendall Steer

Williams Honors College, Honors Research Projects

Addressing difficulties with swallowing is a small, yet critical portion of a speech-language pathologist’s role. Infants often experience challenges associated with swallowing safely, yet the ability of SLPs to prescribe effective interventions is limited by the lack of knowledge on how anatomy and physiology interact to drive these challenges. The goal of my Honors Research Project is to address this lack of knowledge by determining how the infant pig tongue moves during feeding from a bottle versus drinking from a bowl, as well as how the muscles controlling the tongue differ in these behaviors. I used infant pigs for this …

Comparison Of Machine Learning Methods For Classification Of Alexithymia In Individuals With And Without Autism From Eye-Tracking Data, Furkan Iigin, Megan A. Witherow, Khan M. Iftekharuddin

Electrical & Computer Engineering Faculty Publications

Alexithymia describes a psychological state where individuals struggle with feeling and expressing their emotions. Individuals with alexithymia may also have a more difficult time understanding the emotions of others and may express atypical attention to the eyes when recognizing emotions. This is known to affect individuals with Autism Spectrum Disorder (ASD) differently than neurotypical (NT) individuals. Using a public data set of eye-tracking data from seventy individuals with and without autism who have been assessed for alexithymia, we train multiple traditional machine learning models for alexithymia classification including support vector machines, logistic regression, decision trees, random forest, and multilayer perceptron. …

The experimental group received twice-daily doses of Advair HFA™ (fluticasone propionate 45 mcg and salmeterol 21 mcg) via a veterinary facemask with 1-way valve and spacer; the control group received aerosolized saline. After 8 weeks, animals were euthanized, larynges excised, frozen, and subsequently thawed and mounted on a standard bench apparatus. Phonation was elicited during 15 successive trials, and phonation threshold pressure …

Investigation To Examine The Profile Of Auditory Brainstem And Hearing Thresholds Using Tone Burst Audiometry Brainstem Response In A Preclinical Migraine Model, Megan Huelsing

Graduate Theses/Dissertations

Migraine is a disabling neurological disease that is characterized by prominent auditory symptoms, including hyperacusis, which is defined as extreme sensitivity to sounds. The goal of this study was to investigate changes in hearing sensitivity and neural changes in the brainstem by measuring neural activity of the auditory brainstem in an established preclinical model of chronic migraine. To induce a chronic migraine state within the trigeminal system, male and female Sprague Dawley rats were subjected to three known human risk factors including neck muscle tension and REM sleep deprivation that promote latent sensitization, and exposure to a pungent odor, which …
