Abstract 1- Introduction: Charcot-Marie-Tooth (CMT) disease is a rare and chronic hereditary disorder that causes motor and sensory damage to the peripheral nervous system. As the disease progresses, hearing sensitivity may worsen. Case Presentation: A young adult-aged patient presented to the clinic with congenital hearing loss and difficulty with conversational speech in quiet and noisy conditions. Discussion: When encountering a patient with CMT, clinicians should be cognoscente of amplification options, especially if nerve pathways begin to deteriorate. When audiologic testing reveals a progression of hearing loss, alternative amplification may be indicated because conventional hearing aids may not provide enough …


Audiological Intervention For Late-Identified Children And Teenagers With Hearing Loss, Melissa Wiedeman, Antony Joseph Mar 2023

Audiological Intervention For Late-Identified Children And Teenagers With Hearing Loss, Melissa Wiedeman, Antony Joseph

AuD Capstone Projects - Communication Sciences and Disorders

Abstract 1 - Introduction: The family of every child referred for definitive care after a newborn hearing screening should follow up with an audiologist to rule out hearing impairment. Early identification, diagnosis, and intervention are crucial for individualized planning and outcomes. Children who need binaural amplification and are not managed appropriately become exposed to sound deprivation, which leads to diminished speech audibility, sound localization, and speech and language development. Case Presentation: A young child presented to the clinic with an unspecified bilateral mild to moderate hearing loss at 500, 2000, and 4000 Hz. Discussion: Children with monaural amplification have shown …

This study examined the question: “What is the role of Augmentative and Alternative Communication (AAC) devices in aiding individuals across the autism spectrum and what perspectives do parents of children across the autism spectrum have with regard to this technology?” This study involved interviewing a parent of an autistic child to glean her perspectives on AAC. The findings from this interview guided the meta-analysis research. Three main categories arose: benefits of AAC, disadvantages of AAC and parent …


Data From: A Protracted Developmental Trajectory For English-Learning Children’S Detection Of Consonant Mispronunciations In Newly Learned Words, Carolyn Quam, Daniel Swingley Apr 2022

Data From: A Protracted Developmental Trajectory For English-Learning Children’S Detection Of Consonant Mispronunciations In Newly Learned Words, Carolyn Quam, Daniel Swingley

Speech and Hearing Sciences Faculty Datasets

Children are adept at learning their language’s speech-sound categories, but just how these categories function in their developing lexicon has not been mapped out in detail. Here, we addressed whether, in a language-guided looking procedure, two-year-olds would respond to a mispronunciation of the voicing of the initial consonant of a newly learned word. First, to provide a baseline of mature native-speaker performance, adults were taught a new word under training conditions of low prosodic variability. In a second experiment, 24- and 30-month-olds were taught a new word under training conditions of high or low prosodic variability. Children and adults showed …

The Effects Of Acidic Foods On Vocal Quality Of Vocally Healthy Individuals, Melissa Barbieri Jun 2021

The Effects Of Acidic Foods On Vocal Quality Of Vocally Healthy Individuals, Melissa Barbieri

FIU Electronic Theses and Dissertations

The purpose of the current study was to examine the relationship between the consumption of acidic liquids on the vocal quality of vocally healthy individuals. Acidic foods and liquids are known to be possible causes of common voice disorders because of their putative effect on systemic hydration of the vocal folds impacting their viscoelastic properties and eventually affecting vocal quality, as they are found in over 50% of dysphonic patients (Karkos et al., 2007). This study investigated the effects of acidic foods on vocal quality in comparison to the effects of non-acidic/alkaline beverages in vocally healthy individuals.

One hundred participants …


Creating A Theoretical Framework To Underpin Discourse Assessment And Intervention In Aphasia, Lucy Dipper, Jane Marshall, Mary Boyle, Deborah Hersh, Nicola Botting, Madeline Cruice Feb 2021

Creating A Theoretical Framework To Underpin Discourse Assessment And Intervention In Aphasia, Lucy Dipper, Jane Marshall, Mary Boyle, Deborah Hersh, Nicola Botting, Madeline Cruice

Department of Communication Sciences and Disorders Faculty Scholarship and Creative Works

Discourse (a unit of language longer than a single sentence) is fundamental to everyday communication. People with aphasia (a language impairment occurring most frequently after stroke, or other brain damage) have communication difficulties which lead to less complete, less coherent, and less complex discourse. Although there are multiple reviews of discourse assessment and an emerging evidence base for discourse intervention, there is no unified theoretical framework to underpin this research. Instead, disparate theories are recruited to explain different aspects of discourse impairment, or symptoms are reported without a hypothesis about the cause. What is needed is a theoretical framework that …

As well, we discuss studies that address the recently debated topic of cognitive processes in bilingual individuals with aphasia, with a focus on the effects of bilingualism on aphasia recovery and its potential protective effects.

Recent Findings

Providing assessment and treatment tools that best serve multilingual individuals with aphasia and unpacking the variables and mechanisms that underlie response to treatment have emerged as goals of several recent studies. Additionally, while findings are still …


Strengthening The Semantic Verb Network In Multilingual People With Aphasia: Within- And Cross-Language Treatment Effects, Aviva Lerman, Mira Goral, Lisa Edmonds, Loraine K. Obler Jan 2021

Strengthening The Semantic Verb Network In Multilingual People With Aphasia: Within- And Cross-Language Treatment Effects, Aviva Lerman, Mira Goral, Lisa Edmonds, Loraine K. Obler

Publications and Research

In multilingual people, semantic knowledge is predominantly shared across languages.
Providing semantic-focused treatment to people with aphasia has been posited to strengthen
connectivity within association cortices that subserve semantic knowledge. In multilingual people, such treatment should result in within- and cross-language generalisation to all languages, although not equally. We investigated treatment effects in two multilingual participants with aphasia who received verb-based semantic treatment in two pre-stroke highly
proficient languages. We compared within- and cross-language generalisation patterns across languages, finding within- and cross-language generalisation after treatment in the less-impaired, pre-morbidly more-proficient first-acquired language (L1). This observation supports the theory that connectivity …

The Ongoing Disparity Between Early Intervention Services And Those Who Need Them, Addison Goerl Oct 2020

The Ongoing Disparity Between Early Intervention Services And Those Who Need Them, Addison Goerl

Honors Theses

Although early intervention (EI) services have been shown to be highly effective and beneficial for young children, only 12% of those who qualify at 24 months receive services (Feinberg et al., 2011). There is a myriad of barriers that impedes access to EI services for those who need them. These barriers include myths about development and intervention, parent’s concerns being ignored, social inequalities limited access to early intervention, systemic barriers within the professional world, unperceived benefits of intervention, and limited communication flow to parents. However, there are some supports that help more families access EI services including doctors, early interventionists, …


Infants’ Discrimination Of Consonant Contrasts In The Presence And Absence Of Talker Variability, Carolyn Quam, Lauren Clough, Sara Knight, Louann Gerken Oct 2020

Infants’ Discrimination Of Consonant Contrasts In The Presence And Absence Of Talker Variability, Carolyn Quam, Lauren Clough, Sara Knight, Louann Gerken

Speech and Hearing Sciences Faculty Publications and Presentations

To learn speech‐sound categories, infants must identify the acoustic dimensions that differentiate categories and selectively attend to them as opposed to irrelevant dimensions. Variability on irrelevant acoustic dimensions can aid formation of robust categories in infants through adults in tasks such as word learning (e.g., Rost and McMurray, 2009) or speech‐sound learning (e.g., Lively et al., 1993). At the same time, variability sometimes overwhelms learners, interfering with learning and processing. Two prior studies (Kuhl & Miller, 1982; Jusczyk, Pisoni, & Mullennix, 1992) found that irrelevant variability sometimes impaired early sound discrimination. We asked whether variability would impair or facilitate discrimination …


Variables And Mechanisms Affecting Response To Language Treatment In Multilingual People With Aphasia, Mira Goral, Aviva Lerman Sep 2020

Variables And Mechanisms Affecting Response To Language Treatment In Multilingual People With Aphasia, Mira Goral, Aviva Lerman

Publications and Research

Background: Despite substantial literature exploring language treatment effects in multilingual people with aphasia (PWA), inconsistent results reported across studies make it difficult to draw firm conclusions. Methods: We highlight and illustrate variables that have been implicated in effecting cross-language treatment effects in multilingual PWA. Main contribution: We argue that opposing effects of activation and inhibition across languages, influenced by pertinent variables, such as age of language acquisition, patterns of language use, and treatment-related factors, contribute to the complex picture that has emerged from current studies of treatment in multilingual PWA. We propose a new integrated model—Treatment effects in Aphasia in …

The study was run on 50 participants, who each completed an accent imitation ability assessment, a musical ability assessment, and an articulation ability assessment. The scores for the accent imitation portion were rated by anonymous online raters. Each participant filled out a questionnaire on prior musical experience and were either classified as a musician or non-musician. The analysis found that those in the musician group performed better on the musical ability, articulation, and accent ability assessment than non-musicians. …


Perceptions Of Guilt Of Individuals With A Visible Communication Disorder Versus An Invisible Communication Disorder, Zoe Hochberg May 2020

Perceptions Of Guilt Of Individuals With A Visible Communication Disorder Versus An Invisible Communication Disorder, Zoe Hochberg

Honors Scholar Theses

This study explored how communication disorders may impact listeners’ perception of guilt. More specifically, it looked at how visible communication disorders (e.g., stuttering) and invisible communication disorders (e.g., high functioning autism) are judged by the general public. 51 adults (18-71 years) participated in the study which asked them to view video recordings of narrative samples produced by an individual who stuttered (PWS), an individual with high-functioning autism (PHFA), and an individual with no communication disorder (PNCD). Participants were not informed of the individuals’ communication abilities (PWS, PHFA, or PNCD), but were told that one of the individuals had committed a …


Effects Of Speech Cues In French-Speaking Children With Dysarthria, Erika S. Levy, Gemma Moya-Galé, Younghwa Michelle Chang, Luca Campanelli, Andrea A. N. Macleod, Sergio Escorial, Christelle Maillart Feb 2020

Effects Of Speech Cues In French-Speaking Children With Dysarthria, Erika S. Levy, Gemma Moya-Galé, Younghwa Michelle Chang, Luca Campanelli, Andrea A. N. Macleod, Sergio Escorial, Christelle Maillart

Publications and Research

Background: Articulatory excursion and vocal intensity are reduced in many children with dysarthria due to cerebral palsy (CP), contributing to the children’s intelligibility deficits and negatively affecting their social participation. However, the effects of speech-treatment strategies for improving intelligibility in this population are understudied, especially for children who speak languages other than English. In a cueing study on English-speaking children with dysarthria, acoustic variables and intelligibility improved when the children were provided with cues aimed to increase articulatory excursion and vocal intensity. While French is among the top 20 most spoken languages in the world, dysarthria and its management in …


Inner Ear Disorders Associated With Hearing And Vestibular Loss: A Case Series, Kelly Retzlaff Jan 2020

Inner Ear Disorders Associated With Hearing And Vestibular Loss: A Case Series, Kelly Retzlaff

AuD Capstone Projects - Communication Sciences and Disorders

Introduction: Sudden sensorineural hearing loss (SSNHL), a hearing loss of at least 30 dB at three or more consecutive frequencies within a 72-hour period, is typically idiopathic. Potential causes are thought to include viral, autoimmune, vascular, neurologic, neoplastic, or traumatic origins. Treatment consists of steroids. Poor patient follow up and compliance with rehabilitation negatively affect outcomes. Poor follow-up also results in the inadequate medical documentation of outcomes. Case Presentation: a 20-year old female presented with unilateral SSNHL with high-frequency tinnitus in the right ear. Her audiological history includes a known profound hearing loss in the left ear, as well as, …

Average Speech Directivity, Samuel D. Bellows, Claire M. Pincock, Jennifer K. Whiting, Timothy W. Leishman Nov 2019

Average Speech Directivity, Samuel D. Bellows, Claire M. Pincock, Jennifer K. Whiting, Timothy W. Leishman

Directivity

Speech directivity describes the angular dependence of acoustic radiation from a talker’s mouth and nostrils and diffraction about his or her body and chair (if seated). It is an essential physical aspect of communication affecting sounds and signals in acoustical environments, audio, and telecommunication systems. Because high-resolution, spherically comprehensive measurements of live, phonetically balanced speech have been unavailable in the past, the authors have undertaken research to produce and share such data for simulations of acoustical environments, optimizations of microphone placements, speech studies, and other applications. The measurements included three male and three female talkers who repeated phonetically balanced passages …

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 Jul 2019

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 …
