It examines the definition of a Cerebrovascular accident (CVA), and the various symptoms that occur when the left versus the right hemisphere is affected. The different causes of strokes are taken into account, along with the wide range of ways the victims may be affected by it, physically and mentally. It is important to be familiar with the different methods of treatment for a patient …

Under-Reactive But Easily Distracted: An Fmri Investigation Of Attentional Capture In Autism Spectrum Disorder, Brandon Keehn, Aarti K N Nair, Alan J. Lincoln, Jeanne Townsend, Ralph Axel Müller

Department of Speech, Language, and Hearing Sciences Faculty Publications

For individuals with autism spectrum disorder (ASD), salient behaviorally-relevant information often fails to capture attention, while subtle behaviorally-irrelevant details commonly induce a state of distraction. The present study used functional magnetic resonance imaging (fMRI) to investigate the neurocognitive networks underlying attentional capture in sixteen high-functioning children and adolescents with ASD and twenty-one typically developing (TD) individuals. Participants completed a rapid serial visual presentation paradigm designed to investigate activation of attentional networks to behaviorally-relevant targets and contingent attention capture by task-irrelevant distractors. In individuals with ASD, target stimuli failed to trigger bottom-up activation of the ventral attentional network and the cerebellum. …

Differential Effects Of Cdh23753a On Auditory And Vestibular Functional Aging In C57bl/6j Mice, Bruce E. Mock, Sarath Vijayakumar, Jessica Pierce, Timothy A. Jones, Sherri M. Jones

Department of Special Education and Communication Disorders: Faculty Publications

The C57BL/6J (B6) mouse strain carries a cadherin 23 mutation (Cdh23^753A, also known as Ahl), which affects inner ear structures and results in age-related hearing loss. The B6.CAST strain harbors the wild type Cdh23 gene, and hence, the influence of Ahl is absent. The purpose of the present study was to characterize the effect of age and gender on gravity receptor function in B6 and B6.CAST strains and to compare functional aging between auditory and vestibular modalities. Auditory sensitivity declined at significantly faster rates than gravity receptor sensitivity for both strains. Indeed, vestibular functional aging was …

Infant-Driven Feeding Vs. Scheduled Feeding: The Effect On Hospital Length Of Stay, Lori L. Messer

Walden Dissertations and Doctoral Studies

Developmental delays related to feeding dysfunction in premature infants can lead to lengthy hospitalizations and increased healthcare costs initially and throughout the first year of the child's life. The purpose of this project was to use readiness-to-feed assessments to evaluate the impact of an infant-driven feeding protocol on length of stay. The project compared the length of stay of 2 groups of infants: a demand fed according to a readiness-to-feed protocol (protocol group, n = 14) and a traditionally fed according to scheduled, volume-driven feedings (traditional group, n = 15). The logic model served as the change management framework and …

The purpose of this study was to investigate the effectiveness of augmentative and alternative communication (AAC) programs in improving the communication needs and lives of people affected by aphasia. Individuals (n = 20) suffering from aphasia for 3 months or more completed therapy sessions with speech and language pathologists and the AAC program. Pre- and post-intervention evaluations were administered, consisting of communication satisfaction and success questionnaires, the Western Aphasia Battery (WAB), and probing tests (prompt and response) with an …

Fundamental Frequency Characteristics Of Modal And Vocal Fry Registers, Heidi Brubaker, Jason Albertson Whitfield Ph.D., Jane Schoonmaker Rodgers D.M.A.

Honors Projects

This study examined the distribution of fundamental frequencies in the connected speech of 14 healthy young adults. Acoustic analysis of fundamental frequency was performed on previously collected speech samples of a phonetically balanced reading passage. For the first three sentences of the reading passage, fundamental frequency contours were extracted using PRAAT, a speech analysis software package. The accuracy of these contours were visually verified and manually corrected when needed. The distribution of the fundamental frequency histories for each sample were then analyzed using Gaussian Mixture Model analyses in MATLAB. For most speakers, four statistical modes were identified in the data …

Autism Spectrum Disorder: How Does Transitional Planning From Preschool To Elementary School Benefit Educational And Social Success?, Shakeika K. Everett

Honors Theses

Autism Spectrum Disorder (ASD) is a disorder that impacts millions of people worldwide on a daily basis. While most adults with autism have received, and continue to receive, the proper assistance in engaging in everyday life, children with autism face more challenges that impacts their engagement socially. Many intervention methods have been researched and implemented to assist in communication and social involvement for children with ASD. However, little research exists on helping young children with ASD effectively transition, both academically and socially, from one educational environment to another. This research will contain a case study of a six-year-old child enrolled …

Exploring The Clinical Utility Of Relative Fundamental Frequency As An Objective Measure Of Vocal Hyperfunction, Christopher Dromey, Nelson Roy, Rebecca A. Fetrow, Ray M. Merrill

Faculty Publications

Purpose: Vocal hyperfunction, related to abnormal laryngeal muscle activity, is considered the proximal cause of primary muscle tension dysphonia (pMTD). Relative fundamental frequency (RFF) has been proposed as an objective acoustic marker of vocal hyperfunction. This study examined (a) the ability of RFF to track changes in vocal hyperfunction after treatment for pMTD and (b) the influence of dysphonia severity, among other factors, on the feasibility of RFF computation. Method: RFF calculations and dysphonia severity ratings were derived from pre- and posttreatment recordings from 111 women with pMTD and 20 healthy controls. Three vowel–voiceless consonant–vowel stimuli were analyzed. Results: RFF …

Laryngeal Desiccation Challenge And Nebulized Isotonic Saline In Healthy Male Singers And Nonsingers: Effects On Acoustic, Aerodynamic, And Self-Perceived Effort And Dryness Measures, Christopher Dromey, Kristine Tanner, Robert B. Fujiki, Ray M. Merrill, Whitney Robb, Katherine A. Kendall, J Arden Hopkin, Ron W. Channell, M Preeti Sivasankar

Faculty Publications

Summary: Objectives. This study examined the effects of a laryngeal desiccation challenge and nebulized isotonic saline on voice production in young, healthy male singers and nonsingers. Study design. This is a prospective, double-blind, within-subjects experimental design. Methods. Participants included 10 male university-trained singers and 10 age-matched nonsingers (mean age, 21.8 years; range, 18–26 years) who underwent a 30-minute oral breathing laryngeal desiccation challenge using medical grade dry air (<1% relative humidity) on two occasions in consecutive weeks. After the challenge, participants received either 3 mL or 9 mL of nebulized isotonic saline (0.9% Na+ Cl); order of administration was counterbalanced. Phonation threshold pressure (PTP), the cepstral spectral index of dysphonia (CSID) for sustained vowels and connected speech, and self-perceived vocal effort, mouth dryness, and throat dryness were measured at each recording (baseline, after challenge, and at 5, 35, and 65 minutes after treatment). Results. Self-perceived effort and dryness measures increased (worsened) after desiccation challenge and decreased (improved) after nebulized treatment (P < 0.05). No consistent changes were observed for PTP or CSID over time. Overall, singers demonstrated significantly lower vocal effort and CSID as compared with nonsingers. Conclusions. Young, vocally healthy men may not experience physiologic changes in voice production associated with laryngeal desiccation and nebulized saline treatments; however, self-reported increases in vocal effort which are associated with dryness symptoms might improve with nebulized treatments. Future hydration research should consider age and sex variables

Preschool Oral Narrative Retell Intervention: A Contextualized Approach, Megan E. Miller

Masters Theses

The purpose of this study was to investigate the efficacy of a contextualized, explicit narrative intervention on oral narrative retell skills in typically developing preschoolers as a means for fostering the development of narrative structure, story comprehension, and narrative retell skills. Participants were recruited from the Childhood Development Laboratory preschool classrooms located in Buzzard Hall at Eastern Illinois University. Prior to intervention, participants' core receptive and expressive language abilities were assessed using the Comprehensive Evaluation of Language Fundamentals-Preschool-2nd Edition (CELF-P-2), and oral narrative retells were analyzed for narrative complexity using the Test of Narrative Retell-Preschool Edition (TNR-P).

Working Memory And Interference Control In Children With Specific Language Impairment, Klara Marton, Naomi Eichorn, Luca Campanelli, Lilla Zakarias

Publications and Research

Language and communication disorders are often associated with deficits in working memory (WM) and interference control. WM studies involving children with specific language impairment (SLI) have traditionally been framed using either resource theories or decay accounts, particularly Baddeley's model. Although significant interference problems in children with SLI are apparent in error analysis data from WM and language tasks, interference theories and paradigms have not been widely used in the SLI literature. A primary goal of the present paper is to provide an overview of interference deficits in children with SLI. Review of the extant literature on interference control shows deficits …

The Contribution Of Self-Regulation To Reading Comprehension In Adolescent Learners, Rebecca Lynn Parker

LSU Doctoral Dissertations

The purpose of this study was to examine the dually implicated processes of language and self-regulation in reading comprehension and to determine if self-regulation contributes unique variance to reading comprehension beyond word recognition/decoding and oral language comprehension. The study also sought to determine if the unique contribution of self-regulation to reading comprehension differs for students with language/learning difficulties and students with typical language/learning histories. Thirty-two 6th, 7th, and 8th graders participated in this study. Of these participants, 17 students had language/learning difficulties and 15 students had typical language/learning histories. All participants attended a low performing public middle school located in …

Towards Improving The Evaluation Of Speech Production Deficits In Chronic Stroke, Artemis Alexandra Basilakos

Theses and Dissertations

One of the most devastating consequences of stroke is aphasia - a disorder that impairs communication across the domains of expressive and receptive language. In addition to language difficulties, stroke survivors may struggle with disruptions in speech motor planning and/or execution processes (i.e., a motor speech disorder, MSD). The clinical management of MSDs has been challenged by debates regarding their theoretical nature and clinical manifestations. This is especially true for differentiating speech production errors that can be attributed to aphasia (i.e., phonemic paraphasias) from lower-level motor planning/programming impairments (i.e., articulation errors that occur in apraxia of speech; AOS). Therefore, the …

Neural And Behavioral Correlates Of Planning During Vocal Motor Control, Stacey Jean Sangtian

Theses and Dissertations

Speech is a goal-directed movement developed to serve the purpose of human communication. During speech, the brain simultaneously coordinates complex motor behavior and sensory information for planning, execution and online monitoring for error correction in order to ensure accurate delivery of the vocal messages. Models of speech production and voice motor control have adapted the principles of the internal forward model to explain that speech sound production is controlled by comparison of internal predictions with sensory feedback. Growing evidence from studies conducted in speech and limb motor movement indicate that these sensory predictions and responsive commands are loaded in anticipation …

Determining The Validity Of A Web-Based, Self-Rating Checklist Assessment Of Vocabulary Knowledge, Sheida Abdi

Theses and Dissertations

The purpose of this study is to examine the validity of a web-based, self-rating checklist of vocabulary knowledge. One hundred fifty-nine participants took two norm-referenced assessments in addition to one of three conditions of a developed self-rating checklist. Each condition employed a different combination of follow-up questions (synonym generation to verify participants’ self-ratings) and feedback for student responses (whether or not synonyms are correct). Condition 1 did not provide any follow-up questions or feedback, Condition 2 included follow-up questions and feedback, and Condition 3 presented follow-up questions but no feedback. Results show that participants moderately overestimated vocabulary knowledge. Moderate-to-high statistically …

Parkinson’s disease is the second most common neurodegenerative disorder therefore, it is important for clinicians to be educated about the voice treatments that can used to decrease the vocal symptoms of Parkinson’s disease. This study was conducted by having members of the American Speech-Language-Hearing Association fill out an online survey. The results indicated that speech-language pathologists who considered themselves to be …

Articulatory-Acoustic And Kinematic Relationships In Comfortable And Loud Speech, Christopher Dromey, Jason A. Whitfield, Panika Palmer

Faculty Publications

During speech, movements of the vocal tract systematically alter vowel acoustics. A number of investigations have examined these articulatory acoustic relationships (e.g., Mefferd & Green, 2010). Studies have shown that systematic changes in speaking style, such as in clear or loud speech, yield greater excursions of articulatory gestures that are accompanied by an expansion of formant frequency measures in F1-F2 space (Mefferd & Green, 2010; Tasko & Greilick, 2010). A recent investigation introduced the Articulatory-Acoustic Vowel Space (AAVS), a measure of working formant space that uses continuously sampled formant data from connected speech (Whitfield & Goberman, 2014). No data, however, …
