Dichotic Listening Test Performance In Children, Kairn Stetler Kelley

Graduate College Dissertations and Theses

Dichotic tests evaluate binaural integration through simultaneous presentation of different stimuli to each ear of a listener who has normal hearing sensitivity in both ears. Dichotic listening deficits may lead to problems with language, communication, reading, or academic performance. If accurately identified, dichotic deficits may be treatable with listening training or managed with accommodation. However, it is not clear which of several commercially-available dichotic test recordings are best for audiologists to use when assessing binaural integration in children. Literature review revealed limited evidence of reliability, accuracy, usefulness, or value for dichotic tests applied to children. Of 11 dichotic tests identified, …

Physiological And Behavioral Evidence Of Auditory Processing Deficit In Children Suspected Of Auditory Processing Disorder, Sangamanatha Ankmnal Veeranna

Electronic Thesis and Dissertation Repository

A series of studies were carried out to examine the neural and behavioral processing of acoustic stimuli in children with suspected auditory processing disorder (sAPD).

The click-evoked auditory brainstem responses recorded from children with sAPD and adults were analyzed using traditional clinical measures and detailed analysis seeking to explore the separate contributions of axonal conduction and synaptic transmission. Clinical measures revealed significant prolongation of absolute latencies and interwave intervals in children with sAPD compared to adults. Examination of responses delineating axonal vs. synaptic transmission showed frequent delays in synaptic factors and fewer instances of delays related to axonal conduction in …

The Effect Of Chronic Obstructive Pulmonary Disease On Swallowing, Jessica R. Torres

Senior Honors Projects, 2010-2019

This work is composed of a literature review, research review, and self-reflective essay. The anatomy and physiology of normal swallowing and respiration are reviewed. Additionally, the effect of chronic obstructive pulmonary disease (COPD) on these processes is discussed. The research goal was to determine how lung volume changes adapt the physiology of swallowing in individuals with COPD. The research project was designed and conducted by Teresa Drulia, M.S., CCC-SLP. COPD participants (n=9, mean age=72, 6 male) were compared to older healthy individuals (n=10, mean age= 59, 3 male). Participants completed swallows of 20cc of water at four lung volume conditions: …

The Effects Of Lung Volume On Swallowing In Chronic Obstructive Pulmonary Disease, Teresa C. Drulia

Dissertations, 2014-2019

Chronic Obstructive Pulmonary Disease (COPD), a respiratory disease that leads to reduced airflow, may result in difficulty swallowing with disease progression. The coordination between the respiratory and swallowing systems decouple and they may experience increased risk of aspiration. This study aimed to determine the effects of lung volume on swallowing in individuals with COPD compared with older healthy. Specifically, the study examined if altering lung volume at the time of the swallow changed swallowing timing, specifically pharyngeal swallow duration, and impacted the respiratory-swallow pattern in individuals with COPD. Measurement of estimated lung volume (ELV), pharyngeal swallow duration, and respiratory-swallow patterning …

Teacher Candidates: Vocal Health, Sarah J. Pilkington

Honors Projects

Classroom teachers are at high risk for developing voice problems and may experience positive benefits from vocal health education. Less is known about the experiences of student teachers. The objective of the study was to determine if vocal hygiene education affects the student teachers’ vocal knowledge, vocal habits, voice quality, and their self-perception of their voice. Eight female education students who were student teaching the semester of the study were randomized into either the Experimental Group (who received vocal health information before their student teaching semester) or the Control Group. Both groups were assessed using a battery of qualitative and …

Video Modeling For Social Communication In Adults With Asd, Haley Ann Altman

Honors Projects

Individuals with autism spectrum disorder (ASD) can experience significant difficulty and psychosocial toll as a result of their impairments in social communication. Specifically for adults, this can have a negative effect on relationships and vocational stability. However, there is a lack of effective intervention for adults with ASD to assist in learning these social conventions. Video modeling is an intervention that has potential to help these individuals learn to be successful in social problem-solving situations. A pilot feasibility study (Hewitt & Kelliher, n.d.) was conducted to investigate the intervention of video modeling for adults with ASD. Coding was then necessary …

Topic Manipulation In Five Children With Language Impairment In Response To Topic Probes, Kimberly Kasey Baker

Theses and Dissertations

This study describes a series of case studies on topic management patterns of five children (ages 5 to 10 years) with language impairment. The children participated in semi-structured topic tasks that assessed conversational abilities on topics that were verbally introduced and topics that were introduced both verbally and with an object. Although there was considerable variability among participants, the children generally responded to most introductions by acknowledging and maintaining the topic. With the exception of one child, however, the children in this study demonstrated immature topic manipulation patterns that could be expected to have negative social ramifications.

Preventing Vocal Fold Dehydration Using Aerosolized Salinein An Excised Porcine Model, Mallory Lynn Hansen

Theses and Dissertations

Vocal fold hydration is important for efficient oscillation during voice production. Dehydration of the vocal fold surface is believed to produce adverse effects on the voice. Specifically, low environmental humidity, mouth breathing, and certain medical conditions may contribute to laryngeal and vocal fold dehydration. This dehydration effect may be quantified using the observed pressure and flow at the onset of phonation, operationally defined as phonation threshold pressure (PTP) and phonation threshold flow (PTF), respectively. Previous research has documented that nebulized isotonic saline (0.9% Na+Cl-) can reduce PTP. Additionally, the topical application of liquid saline increases vocal fold hydration in excised …

Development Of Psychometrically Equivalent Speech Recognition Threshold Materials For Native Cebuano Speakers, Melissa Dawn Anderson

Theses and Dissertations

While there is a clear and immediate need for reliable speech audiometry materials to evaluate the speech recognition threshold (SRT), these recorded materials are not available in Cebuano, a language of the Philippines with 15.8 million speakers. The purpose of this study was to develop, digitally record, evaluate, and psychometrically equate a set of Cebuano trisyllabic words for use in measuring the SRT. To create the SRT materials, common Cebuano trisyllabic words were digitally recorded by a male talker of Cebuano and presented for evaluation to 20 native speakers of Cebuano with normal hearing. Based on psychometric performance, a set …

The Ability Of Six Children With Language Impairment To Generate Stories From Pictured Stimuli: A Pilot Study, Molly Roxanne Alldredge

Theses and Dissertations

Narrative production and comprehension is a difficult task for children with language impairment (LI). Their stories are typically shorter and contain more grammatical errors than the stories of typically developing age-matched peers. This pilot study describes the abilities of six children with LI to produce stories from pictured stimuli. Stories were elicited from each child during a 10-week period. Stimulus pictures and coding procedures from the Edmonton Narrative Norms Instrument were employed to analyze the participants' story grammar (SG). Eight SG elements were assessed including character introduction, setting, initiating event (IE), internal response (IR), internal plan (IP), attempt, and outcome. …

Hormone Replacement Therapy (Hrt) Modulates Peripheral And Central Auditory System Processing With Aging, Tanika Williamson

USF Tampa Graduate Theses and Dissertations

After the findings were reported for the Women’s Health Initiative (WHI) study in the past decade, there has been a significant decline in the overall use of hormone replacement therapy (HRT) among women. However, there are still millions of middle-aged, menopausal women in the U.S. who are currently undergoing hormone therapy. Their reasons for continuing treatment include relief of severe menopausal symptoms, aid in the management of osteoporosis and reduction in the risk of colon cancer (Ness et al., 2005). The purpose of the following investigation was to evaluate the impact of HRT on the central and peripheral auditory systems …

A New Articulation Test Applied To A Selected Group Of Children Living In The State Of New Mexico, Robert Edwin Burkhalter

Speech and Hearing Sciences ETDs

Bilingualism is much more prevalent in the United States than is commonly believed. Goodykoontz points out that "one child in every five, aged fourteen years or under, is of foreign born or mixed parentage." Since our country is still a melting pot of the world where large numbers of citizens converse in other tongues and where many children still enter our schools without speaking a word of English, the problem of bilingualism and foreign dialect will frequently be encountered by the school teacher.

Perception And Production Of /V/ And /W/ In Hindi Speakers, Vikas Grover

Dissertations, Theses, and Capstone Projects

This dissertation examines the ability of Hindi speakers to identify, discriminate and produce two English phonemes /v/ and /w/ which are difficult for Hindi speakers to distinguish. In Hindi, /v/ and /w/ are used interchangeably. This pattern of use has transferred to Indian English, resulting in English /v/ and /w/ words showing variable pronunciations (e.g., “whale” or “vale” for the word “whale”). Hindi speakers were asked to identify, discriminate and produce tokens of /v/ and /w/. This study also examined whether experience with American English, related to the length of residence (LOR) in the US affects Hindi listeners’ perception and …

Relative Clause Sentence Comprehension By Japanese-Speaking Children With Specific Language Impairment And Children With Typical Language Development, Miho Sasaki

Dissertations, Theses, and Capstone Projects

Comprehension of sentences with relative clauses was examined in Japanese-speaking children with SLI and children with TLD. The children with SLI showed comparable comprehension with the TLD peers, when the language and memory tests’ scores were controlled. The children with TLD consistently had difficulties in OR sentences than SR sentences, in spite of that Japanese relative clauses are different from English ones. The children with SLI showed the opposite pattern. Working memory rather than language knowledge predicted better the comprehension performance for all the children.

Exploring The Self-Regulatory Behaviors Of Elementary Students With Hearing Loss In Inclusive Classrooms, Kendra Di Bacco

Electronic Thesis and Dissertation Repository

An exploratory, mixed-method and multi-level research design was employed to examine relationships among students’ hearing loss, academic achievement and self-regulation (SR), classroom background noise levels, teachers’ perceptions of inclusion of students who are hard of hearing (HH) and features of classroom instruction that support SR. Data consisted of 10 elementary teachers’ perceptions of the inclusion, and ratings of 131 students’, of whom 8 were hard of hearing, SR and academic achievement scores. Classroom observations were conducted to obtain background noise levels and to examine whether and how teachers implement the features of classroom contexts to support SR within their classroom. …

The Auditory Brainstem Response And Envelope Following Response: Investigating Within-Subject Variation To Stimulus Polarity, Rebekah Taggart

Electronic Thesis and Dissertation Repository

Though the envelope following response (EFR) has potential to become an effective tool for hearing aid validation, studies have observed a considerable degree of within-subject variation with stimulus polarity that could affect its clinical usefulness. This study investigated whether a relationship exists between the polarity-sensitive variation observed in EFR amplitude and that observed in the latencies of a related neural response, the auditory brainstem response (ABR). Low frequency masked clicks and the dual-f₀ stimulus /susaʃi/ were used to evoke alternating polarity ABRs and EFRs, respectively, in 31 normal hearing adults. Maximum and median differences between polarity conditions were calculated. …

Hydration And Vocal Loading On Voice Measures, Anusha Sundarrajan

Open Access Dissertations

Vocal loading adversely affects the healthy larynx. The negative effects of vocal loading are thought to be exacerbated in dry environments, noisy environments, using non-habitual speaking patterns, and voice quality. Advancing age is also thought to be a risk factor for the negative effects of loading. To systematically tease out the effects of these factors on the healthy larynx, three different experiments were conducted. In each experiment, healthy participants produced 45-minutes of child-directed speech. In experiment 1, older, healthy adults produced loud child-directed speech, in the presence of background noise, in both low and moderate humidities, and voice was assessed. …

Assessing Spanish-Speaking Children: A Comparison Of International Practices, Alexis Decker

Honors Projects

According to The National Center for Educational Statistics, 7.7% of all public K-12 students in the United States (US) speak Spanish in the home, representing 76.5% of all English- language learner (ELL) students (2013). Children exposed to two languages are referred to in the literature as ELLs, language minorities and/or bilingual children. As these children enter school, language disorders and differences may become apparent to the Speech-Language Pathologist (SLP). It is the responsibility of the SLP to determine whether a disorder exists or if what is being observed is simply an issue of language difference. As such, it is important …

Predictors Of Language Outcome For Children In The Ontario Infant Hearing Program, Olivia M. Daub

Electronic Thesis and Dissertation Repository

The Ontario Infant Hearing Program (OIHP) provides early interventions (i.e., hearing aids) to children who are hard of hearing (CHH) because research consistently demonstrates their benefit to language outcomes. The impact of pre-fitting language abilities on these outcomes are not well understood.

This retrospective cohort analysis examined the performance of OIHP children on the Preschool Language Scale-4 at the time of (n=47), and after (n=19), initial hearing aid intervention. Regression analyses revealed that, before amplification, hearing loss severity predicted language abilities. However, after amplification, severity of hearing loss did not uniquely predict language achievement, but rather …

The Consequences Of Oromandibular Dystonia On Communicative Participation: A Qualitative Study Of The Insider's Experiences, Lauren Siegel

Electronic Thesis and Dissertation Repository

The purpose of this study was to explore the consequences of oromandibular dystonia (OMD) on communicative participation from the insider’s perspective. Qualitative research methods were used to obtain a self-reported account of the experience of living with OMD. Eight individuals with OMD and dysarthria participated in face-to-face phenomenological interviews. Interviews were transcribed from audio recordings and coded using coding software. The codes were then grouped into larger thematic categories based on salience. Results showed that communicative participation is affected by multiple physical, social, and emotional factors caused by OMD. Furthermore, OMD can have significant effects on an individual’s job, family, …

Analyzing Spelling Errors By Linguistic Features Among Children With Learning Disabilities, Christine Johnson

USF Tampa Graduate Theses and Dissertations

In order to spell fluently and accurately, phonology, orthography, and morphology must be integrated and stored into long term memory (Berninger & Richards, in press; Berninger, Nagy, Tanimoto, Thompson, Abbott, 2015). Children with dysgraphia, dyslexia, and OWL-LD have specific deficits in linguistic processing that impede the cross-mapping of these linguistic elements. This study analyzes the frequency and nature of spelling errors produced by children with dysgraphia, dyslexia, and OWL-LD during an academic writing task in order to determine if known deficits in linguistic processing affect the type and severity of spelling errors made by these children.

The present study analyzed …

Rubrics: Effectiveness Of Feedback, Sadie Louise Winterscheid

MSU Graduate Theses

The purpose of this study was to determine how rubrics affect university graduate students' receptiveness to feedback, their future college assignments, and if they will use rubrics in their own classroom. Two surveys were sent to teachers and teacher candidate graduate students from a Midwestern university. Participants were asked to answer one of the two surveys depending on whether they had their teaching certificate or were working to receive their teaching certificate. The participants answered survey questions about their college experience with rubrics and their experience and opinions of rubrics in their own, or future, classrooms. The research demonstrated that: …

Sleep Deprivation And Recovery: The Effects Of P300 Three And Six Hours Post Recovery, Kimberly A. Brauer

MSU Graduate Theses

The P300 waveform is an auditory evoked potential (AEP) elicited through a decision making process. Due to the endogenous nature of the P300 response, which requires participants to actively respond to an auditory stimuli, it has been used as on objective measure to evaluate the cognitive processes of attention and memory. Previous studies have looked at the P300 before and after sleep deprivation as well as after brief rest periods. Evidence shows that a decline in P300 amplitudes and increase in latency are seen after 24 hours of sleep deprivation and improvements in the P300 are seen after a recovery …

Story Retell Narratives In Five School-Aged Children With Language Impairment, Megan Bradshaw Deere

Theses and Dissertations

Many children identified with Language Impairment (LI) demonstrate difficulty comprehending and producing narratives. Their narratives are often structurally less complex and of overall poorer quality than those produced by their typically developing peers. These difficulties may negatively impact the academic and social success of children with LI. This thesis evaluates the performance of five school-aged children with LI on a story retell probe embedded within an intervention designed to address their social and emotional language abilities. During the 10-week intervention, participants completed a series of story retell probes using wordless picture books. The story stimuli were taken from the Edmonton …

Effects Of A Novel Right Brain Intervention On Stuttering In Familiar And Structured Speech Tasks, Josalyn Elizabeth Perry

USF Tampa Graduate Theses and Dissertations

Over 3 million Americans are disfluent due to developmental stuttering. Current evidence-based treatments typically consist of a rigorous schedule of intensive therapy, followed by the need for maintenance of skills, placing high demands on self-monitoring of one’s speech at all times. Relapse after treatment is very common, at 84%. The demand for further research into treatment possibilities for stuttering is on the forefront. Previous research has connected neural activations in people who stutter (PWS) and people with chronic nonfluent aphasia. The aim of this study was to determine if a novel intervention, based on a treatment for anomia, would change …

Tongue Twisters Quantified: Ultrasound Analysis Of Speech Stability And Speech Errors, Karen Reddick

USF Tampa Graduate Theses and Dissertations

This thesis investigates errors on speech sounds (or phonemes) produced in laboratory speech stimuli designed to generate phonological onset errors. The present study adds to the literature on phonological speech errors with an instrumental analysis of tongue posture during speech error production and an investigation of the nature of speech errors as unintended variation in articulation.

This study utilized ultrasound instrumentation to visualize speech errors made on velar and alveolar stop consonants at the point of stop closure. Two types of errors were of interest, categorical errors and gradient errors. Categorical errors are those that are heard by the listener …

Static And Dynamic Spectral Acuity In Cochlear Implant Listeners For Simple And Speech-Like Stimuli, Benjamin Anderson Russell

USF Tampa Graduate Theses and Dissertations

For cochlear implant (CI) listeners, poorer than normal speech recognition abilities are typically attributed to degraded spectral acuity. However, estimates of spectral acuity have most often been obtained using simple (tonal) stimuli, presented directly to the implanted electrodes, rather than through the speech processor as occurs in everyday listening. Further, little is known about spectral acuity for dynamic stimuli, as compared to static stimuli, even though the perception of dynamic spectral cues is important for speech perception.

The primary goal of the current study was to examine spectral acuity in CI listeners, and a comparison group of normal hearing (NH) …

Interspeech Posture In Spanish-English Bilingual Adults, Merrily Rose Shary

USF Tampa Graduate Theses and Dissertations

Interspeech posture (ISP) is a term used to define the position of a person’s articulators when they are preparing to speak. Research suggests that ISP may be representative of a speaker’s phonological knowledge in a particular language, as determined empirically with ultrasound measures of the tongue in English-French bilinguals (Wilson & Gick, 2014). It is possible, therefore, that measuring ISP could be a diagnostic tool for determining phonological knowledge in bilingual speakers. However, more information on ISP in typical adult bilingual speakers is needed before diagnostic claims can be made. For example, ISP is believed to be language specific, and …

Effects Of A Novel Right Brain Intervention On Stuttering Frequency In Unfamiliar Speech Tasks, Chelsea Beatrice Stewart

USF Tampa Graduate Theses and Dissertations

Developmental stuttering persists in approximately 1% of the United States population. Stuttering has been shown to impact overall quality of life. The present study examines the effects of a Novel Right Brain Intervention on two female participants with persistent developmental stuttering. The aim of the study was to determine whether encouraging greater activation of the right hemisphere, specifically the pre-SMA, via complex left-handed movements, prior to speech production, would lead to a reduced stuttering frequency and severity in people who stutter (PWS). It was hypothesized that each participant would reduce stuttering symptoms and behaviors following the intervention due to the …
