Department of Special Education and Communication Disorders: Faculty Publications

Purpose: This study explored the effects of highconcentration taste manipulation trials on swallow function in persons with sensory-based dysphagia.

Method: Dysphagia researchers partnered with clinical providers to prospectively identify traumatically injured U.S. military service members (N = 18) with sensorybased dysphagia as evidenced by delayed initiation and/or decreased awareness of residue/penetration/ aspiration. Under videofluoroscopy, participants swallowed trials of 3 custom-mixed taste stimuli: unflavored (40% weight/volume [wt/vol] barium sulfate in distilled water), sour (2.7%wt/vol citric acid in 40% wt/vol barium suspension), and sweet–sour (1.11% wt/vol citric acid plus 8% wt/vol sucrose in 40% wt/vol barium suspension). Trials were analyzed and compared …

Motor-Induced Suppression Of The N100 Event-Related Potential During Motor Imagery Control Of A Speech Synthesizer Brain–Computer Interface, Jonathan S. Brumberg, Kevin M. Pitt

Department of Special Education and Communication Disorders: Faculty Publications

Purpose: Speech motor control relies on neural processes for generating sensory expectations using an efference copy mechanism to maintain accurate productions. The N100 auditory event-related potential (ERP) has been identified as a possible neural marker of the efference copy with a reduced amplitude during active listening while speaking when compared to passive listening. This study investigates N100 suppression while controlling a motor imagery speech synthesizer brain–computer interface (BCI) with instantaneous auditory feedback to determine whether similar mechanisms are used for monitoring BCI-based speech output that may both support BCI learning through existing speech motor networks and be used as a …

Uncoordinated Maturation Of Developing And Regenerating Postnatal Mammalian Vestibular Hair Cells, Tian Wang, Mamiko Niwa, Zahra N. Sayyid, Davood K. Hosseini, Nicole Pham, Sherri M. Jones, Anthony J. Ricci, Alan G. Cheng

Department of Special Education and Communication Disorders: Faculty Publications

Sensory hair cells are mechanoreceptors required for hearing and balance functions. From embryonic development, hair cells acquire apical stereociliary bundles for mechanosensation, basolateral ion channels that shape receptor potential, and synaptic contacts for conveying information centrally. These key maturation steps are sequential and presumed coupled; however, whether hair cells emerging postnatally mature similarly is unknown. Here, we show that in vivo postnatally generated and regenerated hair cells in the utricle, a vestibular organ detecting linear acceleration, acquired some mature somatic features but hair bundles appeared nonfunctional and short. The utricle consists of two hair cell subtypes with distinct morphological, electrophysiological …

Involvement Of Adults Who Are Deaf Or Hard Of Hearing In Ehdi Programs, Elizabeth Shuler-Krause, Karl R. White

Journal of Early Hearing Detection and Intervention

Consistent with a position statement of the Joint Committee on Infant Hearing (JCIH, 2007), several key organizations and groups have supported involving deaf and hard of hearing (DHH) adults in Early Hearing Detection and Intervention (EHDI) systems, including providing families of children who are DHH with opportunities to interact with adults who are DHH. This article reviews the available data on the involvement of adults who are DHH in EHDI systems to determine the availability of opportunities for families who have children who are DHH to interact with adults who are DHH, how families feel about these experiences, and to …

Effects Of Frequency Of Early Intervention On Spoken Language And Literacy Levels Of Children Who Are Deaf Or Hard Of Hearing In Preschool And Elementary School, Ann E. Geers, Jean S. Moog, Amanda M. Rudge

Journal of Early Hearing Detection and Intervention

Language delays associated with hearing loss during infancy may have a negative impact on academic development throughout childhood. Early intervention provided by the Moog Center for Deaf Education prior to 36 months of age was quantified, and associations with later outcomes were examined for 50 students who are DHH representing Moog Center alumni. The objective was to determine whether the amount of early intervention (referred to hereafter as dose of early intervention received at the Moog Center during the time children were 0-36 months of age) contributed uniquely to outcomes in preschool (4–6 years) and in elementary school (8–14 years). …

The purpose of this study was to document demographics, characteristics, and long-term outcomes of teenagers and young adults who are deaf or hard of hearing (DHH) and who all attended the Moog Center for Deaf Education for preschool and/or a portion of elementary school. Data were obtained via an online survey that was designed to assess educational, personal, and professional outcomes of individuals who were currently in high school and beyond. Survey questions were about the lives of these individuals after leaving the Moog Center. Participants included 108 individuals who were DHH, ranging from 15 to 32 years of age. …

The Effect Of Retrieval Practice On Vocabulary Learning For Children Who Are Deaf Or Hard Of Hearing, Casey Krauss Reimer

Arts & Sciences Electronic Theses and Dissertations

The goal of the current study was to determine if students who are deaf or hard of hearing (d/hh) would learn more new vocabulary words through the use of retrieval practice than repeated exposure (repeated study). No studies to date have used this cognitive strategy—retrieval practice—with children who are d/hh. Previous studies have shown that children with hearing loss struggle with learning vocabulary words. This deficit can negatively affect language development, reading outcomes, and overall academic success. Few studies have investigated specific interventions to address the poor vocabulary development for children with hearing loss. The current study investigated retrieval practice …

Validation Of A Scale To Measure Phonological And Morphological Knowledge And Skill Of Speech-Language Pathologists And Elementary Teachers, Susan S. Perry

Dissertations

Phonological and morphological skills are crucial to the process of reading. Speech-language pathologists (SLPs) have received advanced trained in these basic foundations of language and could be an untapped resource in our school systems for teaching beginning reading skills. The purposes of this research were to examine SLPs’ and general education elementary (K-6) teachers’ attitudes toward SLPs taking part in reading instruction, to compare the differences in phonological and morphological knowledge and skill among SLPs and teachers, and to assess the performance of the Revised Basic Language Constructs Surveywhen administered to SLPs and teachers.

Results indicated that, although fewer …

Evaluating The Effectiveness Of Motor Planning With Core Vocabulary: A Behavior Analytic Account, Alison Judith Karnes

Graduate Theses and Dissertations

As the prevalence of autism spectrum disorders (ASD) increases, it is important for practitioners to continue to improve evidence-based practices (EBP) for the treatment of ASD symptoms (i.e., impairments in social communication and repetitive behaviors and restricted interests; American Psychiatric Association [APA], 2013). It is estimated that 30-50% of individuals with autism do not acquire functional speech (Wodka, Mathy, & Kalb, 2013). These individuals would make appropriate candidates for Augmentative and Alternative Communication (AAC; Mirenda, 2003). One form of AAC is the speech-generating device (SGD). Over the last ten years, tablet-based technologies including iPad minisⓇ have been emphasized in the …

Aphasia & Stutter Therapy: An Ailment Not To Be Treated, Janae Nieto

Honors Theses

This work demonstrates the history of two common speech and communication disorders: aphasia and stuttering. Once considered incurable diseases, these conditions have since generated rich rehabilitation practices and accompanying schools of thought. The first part of the thesis takes up adult aphasia, excluding cases involving speech and communication disorders due to other mental illnesses. The second half of this project conveys the history of stuttering. The majority of the modern cases analyzed in this thesis focus on developmental stuttering in children; although, different forms of stuttering are embedded in the progression of the therapy history. Each chapter includes a section …

Autoscore: An Open-Source Automated Tool For Scoring Listener Perception Of Speech, Stephanie A. Borrie, Tyson S. Barrett, Sarah E. Yoho Leopold

Psychology Faculty Publications

Speech perception studies typically rely on trained research assistants to score orthographic listener transcripts for words correctly identified. While the accuracy of the human scoring protocol has been validated with strong intra- and inter-rater reliability, the process of hand-scoring the transcripts is time-consuming and resource intensive. Here, an open-source computer-based tool for automated scoring of listener transcripts is built (Autoscore) and validated on three different human-scored data sets. Results show that not only is Autoscore highly accurate, achieving approximately 99% accuracy, but extremely efficient. Thus, Autoscore affords a practical research tool, with clinical application, for scoring listener intelligibility of speech.

Speech-Language Pathologists' Collaboration With Interpreters: Results Of A Current Survey In California, Terry Saenz, Henriette W. Langdon

Faculty Publications

One of the challenges of bilingual speech and language assessment, intervention, and conferencing is the effective collaboration with interpreters in such interpreted interactions when the professional does not share the same spoken language with the client. A survey of California speech-language pathologists who were members of the California Speech-Language-Hearing Association (CSHA) was performed to obtain information on their training to collaborate with, experiences with, and opinions of interpreters. In addition, these professionals were surveyed about the training of the interpreters and suggestions for improvement in interpreted interactions. Findings from 229 participants indicated that: (a) Most of the speech-language pathologists had …

Barriers To Change For Augmentative And Alternative Communication, Lauren E. Brown

Murray State Theses and Dissertations

The purpose of this study was to identify the effects of counseling training on speech language pathologists’ (SLPs) perceived competency to address Attitude Barriers within the augmentative and alternative communication (AAC) assessment process as presented by Beukelman and Mirenda (2005). Counseling techniques, such as the use of the Readiness to Change© tool, are within the scope of practice for SLPs. Unfortunately, there is a lack of research on how to apply these tools and techniques with individuals who use AAC .

A training seminar was conducted to educate participants in the use of the Readiness to Change© tool. Data was …
