Exploring The Temporal Variability Of Speech Intensity, Speech Intelligibility, And Communicative Participation In Individuals With Hypophonia And Parkinson’S Disease, Cynthia Mancinelli

Electronic Thesis and Dissertation Repository

Hypophonia, or reduced speech intensity, is frequently observed in individuals with Parkinson’s disease (PD). This speech deficit can impact speech intelligibility and communicative participation. However, there is little empirical evidence exploring the day-to-day variability of speech and communicative participation in individuals with PD. The purpose of this study is to investigate the temporal variability of acoustic and perceptual speech measures and psychosocial measures in individuals with hypophonia and PD. Additionally, this study seeks to examine the relationships among measures of speech intensity, speech intelligibility, self- and proxy-rated communicative participation, demographic factors, and non-speech factors. Twenty-three participants with PD, 23 primary …

Behavioural And Objective Assessment Of Binaural Hearing In Adult Listeners With Acquired Unilateral Conductive Hearing Loss Before And After Middle Ear Surgery, Parvaneh Abbasalipour

Electronic Thesis and Dissertation Repository

In normally hearing listeners, binaural hearing relies on symmetrical input from the two ears. Previous studies on human listeners have assessed the effect of induced unilateral conductive hearing loss (UCHL) during adulthood via earplugging. These experiments indicated initial difficulty in sound localization followed by gradual improvement due to adaptation to the perturbed binaural cues. The limited duration of earplug use does not represent the consequences of chronic UCHL secondary to disease. Furthermore, there is insufficient information regarding the adaptation of binaural hearing abilities after treatment of late-onset UCHL.

The current study assessed the binaural hearing abilities of adult listeners with …

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 …

Variations In Parent And Teacher Ratings Of Internalizing, Externalizing, Adaptive Skills, And Behavioral Symptoms In Children With Selective Mutism, Evelyn R. Klein, Cesar E. Ruiz, Kylee Morales, Paige Stanley

Communication and Speech Disorders Faculty work

Selective mutism (SM) is an anxiety disorder that impacts communication. Children with SM present concerns to parents and teachers as they consistently do not speak in situations where there is an expectation to speak, such as at school, but speak in other settings where they feel more comfortable, such as at home. The purpose of this study was to investigate the relationship between parents’ and teachers’ perceptions of children with SM on behavioral rating scales and language measures. Forty-two children (22 boys and 20 girls, ranging from 2.4 to 13.8 years, with a mean age of 7.1 years) took part …

Components Of Auditory Closure, Steven Glen Madix

Steven Madix

Auditory closure (AC) is an aspect of auditory processing that is crucial for understanding speech in background noise. It is a set of abilities that allows listeners to understand speech in the absence of important information, both spectral and temporal. AC is evaluated using monaural low-redundancy speech tasks: low-pass filtered words (LPFW), time-compressed words (TCW), and words-in-noise (WiN). Although not previously used, phonemic restoration with words (PhRW) is also a speech task that has been proposed as a measure of AC. In the present study, four tasks of AC, that are listed above, were used to evaluate AC skills in …

Carers have an important role in rehabilitation and the long-term quality of life of a person with RHD. This study explores the information needs for carers following a family member’s right hemisphere stroke throughout different periods of recovery.

Methods/Procedures: Participants completed online surveys and a semi-structured phone interview. Analysis of the interviews revealed four major …

Taste Manipulation And Swallowing Mechanics In Trauma-Related Sensory-Based Dysphagia, Angela M. Dietsch, H. Duncan Dorris, William Pearson, Katie E. Dietrich-Burns, Nancy Pearl Solomon

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 …

Changes In Speech Intelligibility And Acoustic Distinctiveness Along A Speech Rate Continuum In Parkinson’S Disease, Thea Knowles

Electronic Thesis and Dissertation Repository

Asking a person to speak slowly is a common technique in speech therapy for people with Parkinson’s disease (PD). Slowed speaking rates are thought to bring about changes in speech production that make it easier for people with speech impairments associated with PD to be understood, but this is not always the case. Furthermore, research suggests that using faster speech does not necessarily lead to decreases in speech intelligibility for some people with PD. Most studies of rate modification in PD have only included one or two rate adjustments to investigate the relationship between speech rate, intelligibility, and acoustic aspects …

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 …

Multi-Frequency Electrophysiological Estimates Of Auditory Temporal Acuity, Negar Ahzan

Electronic Thesis and Dissertation Repository

Auditory temporal acuity, a listener’s ability to discriminate rapid changes in the envelope of an auditory signal over time, is crucial for understanding speech. Electrophysiological measurement of auditory temporal acuity is beneficial when we cannot achieve reliable behavioural responses. The envelope following response (EFR) evoked by a changing (swept) amplitude-modulated (AM) stimulus is significantly correlated with behavioural measures of temporal acuity in humans. Previous research using AM broadband noise carriers may have been affected by the cancellation of evoked potentials at the measurement electrodes due to out-of-phase interference of parallel responses initiated at different times due to cochlear travelling wave …

Supporting Persons With Dementia In Communicating Their Care Preferences, Vanessa L. Burshnic

USF Tampa Graduate Theses and Dissertations

Person-centered care is important to the quality of life of nursing home residents with dementia. Preference assessments enable person-centered care by documenting residents’ preferred activities. Residents with severe dementia are less likely to have a role in preference assessment due to communication challenges associated with the disease. External supports (visual and text cues) are effective in improving the communication of residents with dementia, but these cues are often not used in practice. Standard assessment (verbal questioning) places greater demands on short-term memory and attention, which are known deficits in dementia.

Applying a within-subjects design, this study evaluated two conditions (standard …

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 …

The Effect Of Narrative Language Intervention On The Language Skills Of Children With Hearing Loss, Stephanie M. Raymond

USF Tampa Graduate Theses and Dissertations

Children with hearing loss have limited auditory access to their native language and struggle to develop appropriate language skills. These children consistently demonstrate less complex oral language output, smaller vocabulary inventories, and delays in overall communicative proficiency. With the extensive implications hearing loss has on language development, a child with hearing loss requires immediate access to appropriate and effective intervention to address deficits and curb long-term language delays. However, there is a paucity of research investigating the effects of various language intervention programs with children with hearing loss. Much of the existing research focuses on the consequences of a selected …

Script Training For Adults Who Stutter, Courtney M. Rankin

USF Tampa Graduate Theses and Dissertations

Treatment for adulthood stuttering traditionally focuses on some combination of stuttering management and fluency management and may also target emotional and cognitive reactions to stuttering. However, long-term gains are often limited, and there is a need for continued development of approaches for mitigating impacts of stuttering. We know of no evidence-based therapy approaches designed to target functional communication in adults who stutter (AWS), despite widespread interest in improving functional communication in members of this speaker group. Script training is an intervention approach designed to improve accuracy and automaticity in functional communication. Script training was originally designed for use with adults …

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 …

Family Impact Of Pediatric Hearing Loss: Findings From Parent Interviews And A Parent Support Group, Kristen L. Haddad, Wendy W. Steuerwald, Lori Garland

Journal of Early Hearing Detection and Intervention

Parents experience numerous stressors tied to their child's diagnosis as deaf or hard of hearing (DHH). This study sought to inquire about the lived experiences of parents with children who are DHH to inform the types of supports that should be provided within an audiology care coordination system. Semi-structured phone interviews were conducted with parents of children under the age of five who are DHH and patients of the Division of Audiology at Cincinnati Children’s Hospital Medical Center (CCHMC). Interview findings informed focus group questions, which were facilitated in a parent support group with parents of children who are DHH …

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). …

Journal of Early Hearing Detection and Intervention

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. …

Neuro-Correlates Of Word Processing Among Four-And-Five-Year-Old Children From Homes Varying In Socio-Economic Status, Wendy Olsen

USF Tampa Graduate Theses and Dissertations

A large body of research relates families’ socioeconomic status (SES) to child language development (Hoff & Tian, 2005). Results from these studies indicate preschoolers from low SES backgrounds may have underdeveloped linguistic foundations required for future academic success (Sirin, 2005; Lacouri & Tissington, 2011). These differences have been said to create a 30 million word-gap between the language experiences of low and middle to high SES children by the age of 3 years. Thus, children who come from lower SES backgrounds often lack the vocabulary knowledge used in school and in textbooks (Hart & Risley, 1995). One index of SES …

A Method Paper For Earplug-Fitting Augmentative Procedures Tested In Groups Of More Experienced And Less Experienced Users Of Hearing Protection, Natalie Dixon, Antony Joseph

AuD Capstone Projects - Communication Sciences and Disorders

Although a long history of research has led to extensive knowledge about hearing protection devices (HPDs), there has been limited research about procedures that provide aid and verification during HPD insertion, although several studies have reported about HPD training. No standard methods have been established for training of earplug use (Takahashi, 2011).

A review of the literature revealed a need for tools that might be used to improve user ability to properly insert HPDs consistently, even in the absence of training, because training is rarely provided in the workplace. The prevailing research question was "Does the use of simple fitting …

Relationships Between Ambient Noise Levels And Vocal Effort When Working As A Restaurant Bartender, Ashley Bautista

Ursidae: The Undergraduate Research Journal at the University of Northern Colorado

Workers in many different fields depend upon their voice for job performance. Vocal load, the way a voice is used and how much it is used, increases as a function of the total time speech is produced and the intensity (“loudness”) of the voice. Speakers tend to increase pitch, intensity, and duration of speech in the presence of noise, known as the Lombard Effect, which can lead to greater vocal fold stress and subsequent risk of vocal injury. In addition to increased risk of vocal injury, high levels of ambient noise might put workers at risk of auditory damage. …

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 …

Feeding Outcomes In Children With Craniofacial Anomalies, Meghan R. Hansen, Shannon M. Theis, Deanna Britton

Student Research Symposium

Feeding disorders in children with craniofacial anomalies, specifically cleft lip and/or palate, have been documented in the literature as a source of parental stress and can lead to difficulties with the early parent-infant bonding process, as well other medical co-morbidities including poor growth, impairment to the respiratory and developmental health of the child, and increased hospitalizations (Miller, 2011). However, there is a dearth of information in the literature regarding atypical craniofacial anomalies and early feeding difficulties. By utilizing an interdisciplinary team approach, we present a series of three case studies of early feeding difficulties in children with varying degrees of …

Socialsibs: The Effects Of A Hybrid Intervention On The Core Social Communicative Behaviors Of Children With Asd, Marissa Montejano

Student Research Symposium

Purpose/Introduction
Social communication challenges are a central feature of autism spectrum disorders (ASD; APA, 2013). Social communication skills are often a key focus of intervention; however, generalization of skills to natural contexts, particularly peer relationships is a challenge for many children on the spectrum (Ferraioli & Harris, 2011; Schreiber, 2011; Wang & Spillane, 2009).

Socialsibs is a hybrid intervention that targets social interaction, communication, and reciprocity using a combination of video modeling and sibling-mediation within a naturalistic behavioral framework. The intervention was examined within a waitlist control design study with children with ASD and their neurotypical siblings. The current poster …

An Ocean Of Brain Waves: Analyzing Methods To Find Erp Signals In The Noise, Andrea Hamblen, Mallary Owen, Lindsay Robb, Susan Wiggins, Sarah Key-Delyria

Student Research Symposium

Questions:
Will the N400 ERP be observed when participants read word pairs that are either related (semantically, causally, hierarchically, or associatively) or unrelated?

Will a replication of a study using word pairs with varying degrees of relatedness produce similar results to the model study in terms of N400 latency and amplitude?

Can results from a robust, easily-recognizable ERP be used to validate methods for the discovery of more subtle ERP’s?

Hypotheses:

It is expected that our results will mirror the findings of our model study, revealing significant negative-going neural activity between 200 and 500ms after seeing the stimulus. We anticipate …
