The Effects Of Cognates On Receptive And Expressive Language Among Typically Developing Preschool Second Language-Learners, Jesica B. Zavala De Guerrero

Open Access Theses & Dissertations

This exploratory study considers the facilitating effects of cognates across language of intervention, seeking to assess potential cross-language generalizations among typically developing preschool bilinguals. Nine bilingual, English-Spanish speakers of preschool age were assigned to one of three experimental groups (an English only group, a Spanish only group, and a bilingual group) or to a control condition. Children in the experimental groups were introduced to a vocabulary intervention that incorporated cognates and non-cognates. Analysis of data suggests the absence of a cognate advantage among preschool age children; furthermore limiting any possible cross-language generalizations. It is plausible to suspect that age may …

The Impact Of Interface Design During An Initial High-Technology Aac Experience: A Collective Case Study Of People With Aphasia, Aimee R. Dietz, Kristy S.E. Weissling, Julie Griffith, Miechelle L. Mckelvey, Devan Macke

Department of Special Education and Communication Disorders: Faculty Publications

The purpose of this collective case study was to describe the communication behaviors of five people with chronic aphasia when they retold personal narratives to an unfamiliar communication partner using four variants of a visual scene display (VSD) interface. The results revealed that spoken language comprised roughly 70% of expressive modality units; variable patterns of use for other modalities emerged. Although inconsistent across participants, several people with aphasia experienced no trouble sources during the retells using VSDs with personally relevant photographs and text boxes. Overall, participants perceived the personally relevant photographs and the text as helpful during the retells. These …

The patterns of sensor activation produced when participants’ tongues made contact with the electropalate during saliva swallows were compared with the patterns of age-matched peers. Individualized goals were developed on …

Cochlear Development And Auditory Function In The Absence Of Thyroid Hormone Transporters Mct8 And Oatp1c1, Richard Sinn

All Graduate Theses, Dissertations, and Other Capstone Projects

Thyroid hormone (TH) is essential for the development and maturation of the nervous system. The thyroid gland secretes an active form of TH, triiodothyronine, and a prohormone, thyroxine, into the blood. TH is charged, which prevents it from passively diffusing across cell membranes and thus requires cell membrane transporters to facilitate its movement into and out of cells. However, whether TH transporters are required for TH-mediated developmental events, including the auditory system, is largely unknown.

The purpose of the present study was to investigate two specific TH transporters, monocarboxylate transporter 8 (Mct8) and organic anion transporting polypeptide 1c1 (Oatp1c1), and …

Narratives By Six Year Old And Nine Year Old Boys: Brute: Institutional, And Non-Institutional Mental Facts, Adam Craig Whipple

Master's Theses

Brute facts, institutional facts, and non-institutional mental facts were studied. The philosophy of constructionism and the theory of intent provided a framework for this research. Intentionality provided the basis for social facts. Brute, institutional, and noninstitutional mental facts were operationally defined. This study analyzed the use of these facts in the narratives of 6-year-old boys and 9-year-old boys. There were a total of 19 participants in this research. This research established brute, institutional, and non-institutional mental facts as appropriate operational categories for studying children's narratives. The 6-year-old boys produced more brute facts than the 9-year-old boys. The 9-year-old boys produced …

Hearing-Aid Safety: A Comparison Of Estimated Threshold Shifts For Gains Recommended By Nal-Nl2 And Dsl M[I/O] Prescriptions For Children, Teresa Y. C. Ching, Earl E. Johnson, Mark Seeto, John H. Macrae

ETSU Faculty Works

Objective: To investigate the predicted threshold shift associated with the use of nonlinear hearing aids fitted to the NAL-NL2 or the DSL m[i/o] prescription for children with the same audiograms. For medium and high input levels, we asked: (1) How does predicted asymptotic threshold shifts (ATS) differ according to the choice of prescription? (2) How does predicted ATS vary with hearing level for gains prescribed by the two prescriptions? Design: A mathematical model consisting of the modified power law combined with equations for predicting temporary threshold shift (Macrae, 1994b) was used to predict ATS. Study sample: Predicted threshold shift were …

Comparison Of Performance On Static And Dynamic Language Tasks Among Typically Developing Preschoolers With Bilingual Experience, Mireya Hernandez

Speech and Hearing Sciences ETDs

The purpose of this study was to evaluate the potential of a graduated prompting format for measuring modifiability in a screening context among preschool children with bilingual experience. The dynamic assessment framework, including graduated prompting, is an alternative to traditional, static assessment of language impairment. Performance on four dynamic language tasks by 16 typically developing 4-year-olds with more English than Spanish experience was compared to performance of 16 matched children on static versions of the same tasks. These included novel adjective learning, semantic comparison, phonological awareness, and false-belief theory of mind tasks. When prompted responses were credited, the dynamic group …

Effects Of Truncation On Language Sample Analysis In Aphasia, Gerasimos Fergadiotis, Heather Harris Wright

Speech and Hearing Sciences Faculty Publications and Presentations

The goal of this study is to determine if the length of a language sample elicited from a person with aphasia (PWA) is of consequence when making inferences about the patient's functional language ability. When conducting a language sample analysis, a sample representing a snapshot in time is used to make inferences about an individual's language capacity in general. However, current findings are inconclusive regarding the ideal length of the language sample necessary to draw valid conclusions about patients (e.g. Heilman, Nockerts, & Miller, 2010).

Measuring Global Coherence In Aphasia, V. Galetto, S. Kintz, T. West, Heather Harris Wright, Gerasimos Fergadiotis

Speech and Hearing Sciences Faculty Publications and Presentations

Discourse coherence may be conceptualized as representing the listener's ability to interpret the overall meaning conveyed by the speaker. Discourse schemas serve as the organizing frameworks for placing the essential discourse elements within a language sample (Bloom, Borod, & Santschi-Haywoor, Pick, & Obler, 1996; Peterson & McCabe, 1983). When the essential elements are provided a logical consistency of the discourse schema is maintained and the listener perceives the discourse as coherent (Ditman & Kuperberg, 2010; Trabasso, van den Broek, & Suh, 1989; van den Broek, Virtue, Everson, Tzeng, & Sung, 2002). Global coherence refers to the ability to semantically relate …

Predicting Language Impairment Status: A Risk Factor Model, Johanna Maria Rudolph

Open Access Dissertations

The etiology of specific language impairment (SLI) is multifactorial. Research has shown that genetic, environmental, and developmental factors may influence the course of its development. Because many of these factors are present even before a child is born, it is possible that a child's risk of developing the disorder can be identified long before grammatical deficits are observed. The goal of this study was to develop and validate a screening tool to discriminate between children with SLI and typically developing (TD) children using risk factor information including gender, family history of communication or reading disorders, socioeconomic status, maternal and paternal …

Developing A Drug Delivery System For Treatment Of Vocal Fold Scarring, Aaron Michael Kosinski

Open Access Dissertations

Vocal fold scarring is an affliction that results in the formation of a disorganized and stiff extracellular matrix (ECM) with abnormal ECM component densities & structures including a significant increase in collagen deposition. It is caused by improper healing post injury and results in profound changes in the biomechanical properties of the vocal folds impairing their ability to generate a normal mucosal wave during phonation.

Finding an effective treatment for vocal fold scarring has been elusive. Currently, treatments seek temporary solutions that correct glottal incompetence and reduce stiffness caused by the scar through the augmentation of the vocal folds using …

Articulatory Distinctiveness Of Vowels And Consonants: A Data-Driven Approach, Jun Wang, Jordan R. Green, Ashok Samal, Yana Yunusova

School of Computing: Faculty Publications

Purpose: To quantify the articulatory distinctiveness of 8 major English vowels and 11 English consonants based on tongue and lip movement time series data using a data-driven approach.

Method: Tongue and lip movements of 8 vowels and 11 consonants from 10 healthy talkers were collected. First, classification accuracies were obtained using 2 complementary approaches: (a) Procrustes analysis and (b) a support vector machine. Procrustes distance was then used to measure the articulatory distinctiveness among vowels and consonants. Finally, the distance (distinctiveness) matrices of different vowel pairs and consonant pairs were used to derive articulatory vowel and consonant spaces …

Modern Prescription Theory And Application: Realistic Expectations For Speech Recognition With Hearing Aids, Earl E. Johnson

ETSU Faculty Works

A major decision at the time of hearing aid fitting and dispensing is the amount of amplification to provide listeners (both adult and pediatric populations) for the appropriate compensation of sensorineural hearing impairment across a range of frequencies (e.g., 160?10000?Hz) and input levels (e.g., 50?75?dB sound pressure level). This article describes modern prescription theory for hearing aids within the context of a risk versus return trade-off and efficient frontier analyses. The expected return of amplification recommendations (i.e., generic prescriptions such as National Acoustic Laboratories?Non-Linear 2, NAL-NL2, and Desired Sensation Level Multiple Input/Output, DSL m[i/o]) for the Speech Intelligibility Index (SII) …

Word Recognition From Continuous Articulatory Movement Time-Series Data Using Symbolic Representations, Jun Wang, Arvind Balasubramanian, Luis Mojica De La Vega, Jordan R. Green, Ashok Samal, Balakrishnan Prabhakaran

School of Computing: Conference and Workshop Papers

Although still in experimental stage, articulation-based silent speech interfaces may have significant potential for facilitating oral communication in persons with voice and speech problems. An articulation-based silent speech interface converts articulatory movement information to audible words. The complexity of speech production mechanism (e.g., co-articulation) makes the conversion a formidable problem. In this paper, we reported a novel, real-time algorithm for recognizing words from continuous articulatory movements. This approach differed from prior work in that (1) it focused on word-level, rather than phoneme-level; (2) online segmentation and recognition were conducted at the same time; and (3) a symbolic representation (SAX) was …

Assessing For And Understanding The Impact Of Hearing Loss In Children, Sally A. Arnold Ph.D.

A Preliminary Study Of The Articulatory And Acoustic Features Of Forward And Backward Tone Placement In Singing, Krista Wyllys

Masters Theses

A variety of terms exist for describing tone quality in singing, and voice scientists, voice therapists, teachers of singing, and students of singing use different terms to describe the same sound. One aspect of tone quality is tone placement. Teachers of singing often rely on imagery and imitation to elicit correct tone placement from students of singing. More concrete data about what produces forward and backward tone placement could supplement singing teachers’ current practice of using imagery and imitation to elicit a desirable tone quality. This study examined forward and backward tone placement to determine the articulatory gestures and acoustic …
