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 …

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 …

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. …

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 …

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 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 …

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 …

Analysis Of Patterns In Handwritten Spelling Errors Among Students With Various Specific Learning Disabilities, Laura Ann Winkler

USF Tampa Graduate Theses and Dissertations

Students diagnosed with specific learning disabilities struggle with spelling accuracy, but they do so for different reasons. For instance, students with dysgraphia, dyslexia, and oral-written language learning disability (OWL-LD) have distinct areas of weakness in cognitive processing and unique difficulties with the linguistic features necessary for accurate spelling (Silliman & Berninger, 2011). This project considered the spelling errors made by such students to determine if their unique learning profiles lead to distinct misspelling patterns.

Academic summaries handwritten by 33 students diagnosed with dysgraphia (n=13), dyslexia (n=15), and OWL-LD (n=5) were analyzed for type/complexity and …

Language-Mixing In Discourse In Bilingual Individuals With Non-Fluent Aphasia, Avanthi Paplikar

Dissertations, Theses, and Capstone Projects

Language-mixing (LM) as defined by Chengappa (2009, p. 417) is an “intra-sentential phenomenon referred to as the mixing of various linguistic units (morphemes, words, modifiers, phrases, etc.), primarily from two participating grammatical systems”. LM is influenced by grammatical, environmental, and social constraints (e.g., Milroy & Wei, 1995; Bhat & Chengappa, 2005). Researchers have suggested that LM in patients with aphasia is a communicative strategy used to achieve successful exchanges between speakers; the effectiveness of this mixing, however, had yet to be demonstrated quantitatively.

In the current study we investigated whether LM is present in bilingual speakers with aphasia, and if …

Reflection: Effect Of Age On Auditory Brainstem Responses In Mice With Epha4 Mutations, Erica L. Hoogerland

Senior Honors Projects, 2010-2019

Presbycusis, or age-related hearing loss is a condition that affects approximately 40% of the population over 65 years of age (Gates & Mills, 2005). Studying the effects of EphA4 mutations (wild type, heterozygous, and homozygous) mice is fundamental in understanding the relationship between onset of age-related hearing loss, in both the mammalian population and the human population. In order to further understanding of age-related hearing loss, the researchers evaluated thirty-six mice in a preliminary study from two months to nine months of age. Following data analysis, the researchers confirmed the results by continuing a second round of testing. The hearing …

Build-Up Effect Of Auditory Stream Segregation Using Amplitude-Modulated Narrowband Noise, Harley J. Wheeler

Senior Honors Projects, 2010-2019

Recent psychoacoustic experiments (Böckmann-Barthel et al., 2014; Deike et al., 2012) have re-examined research regarding stream segregation and the build-up effect. Stream segregation is the ability to discern auditory objects within a stream of information, such as distinguishing one voice amongst background noise or an instrument within an orchestra. Initial works examining this topic proposed that auditory information is not immediately distinguished as various streams, but rather that differences accumulate over time, allowing listeners to segregate information following a period of build-up (i.e., the build-up effect); whereas more current findings indicate a build-up period is unnecessary for segregation. This experiment’s …

Effect Of Epha4 Signaling Mutations On Auditory Function, Michelle R. Gerringer

Dissertations, 2014-2019

Neural pathways underlie the ability of the auditory system to perceive sound. Organization of neural pathways into functional auditory circuitry is accomplished in part by Eph and ephrin signaling proteins. One of these signaling proteins, the EphA4 receptor tyrosine kinase protein, acts as an axon-guidance molecule to aid in target selection and to maintain tonotopicity in the auditory brainstem and midbrain. Genetic mutations of the EphA4 protein have been shown to affect structural auditory development, but there is limited research which shows the functional effects of these mutations. The goal of the present study was to determine the functional effects …

Prepulse Inhibition Of The Acoustic Startle Reflex To Obtain A Psychometric Function In Mice, Robyn Browne

Dissertations, 2014-2019

The acoustic startle reflex (ASR) is an automated motor response to an unexpected and intense auditory stimulus (Ouagazzal, Reiss, & Romand, 2006). When an audible ‘prepulse’ stimulus is presented before the intense, startle-evoking stimulus (SES); the startle reflex response is reduced and this is known as prepulse inhibition (PPI). The degree of ASR inhibition serves as a measure of the behavioral salience of the prepulse (Carlson & Willott, 1996). This study aimed to obtain a psychometric function from the amount of PPI of the ASR that resulted from varying intensity levels of a prepulse stimulus (PPS).

Twelve mice were used …

Release From Masking: Behavioral And Physiological Masking Level Differences, Sarah L. Hodgson

Dissertations, 2014-2019

Binaural hearing offers several advantages over monaural hearing and is believed to be one factor that is involved in the ability to understand speech in background noise. Binaural hearing involves analysis of interaural timing and intensity differences in signals arriving at the two ears which provides listeners with sound localization cues as well as signal in noise detection. When sounds arrive at each ear at slightly different times, there may be a release from the effects of background noise, allowing listeners to detect softer sounds in noise. Masking Level Differences (MLDs) have been widely used to evaluate behavioral binaural processing. …

Variability In Clinically Measured Wideband Acoustic Immittance Over Time In Young And Old Adults, Allison G. Mcgrath

Dissertations, 2014-2019

Wideband acoustic immittance (WAI) measures of the middle ear have the potential to increase our ability to detect changes in the middle ear transfer function not seen using traditional tympanometry. In order to use this new tool diagnostically we must first understand its normal clinical variability. The present study aimed to investigate the variability that occurs when wideband acoustic immittance (WAI) is measured clinically within subjects as a function of subject age, as a function of time, and as a function of pressure. A total of thirty-six ears from eighteen subjects were studied (n=18 young adults ears, n=18 older adult …

Acoustic Correlates Of Speech Naturalness In Post-Treatment Adults Who Stutter: Role Of Speaking Rate, Caylee Jessen

Honors Theses

Purpose: While many stuttering therapy programs can result in a decrease in stuttering behaviors among participants, some clients leave therapy with speech sounding unnatural due in part to the therapy techniques themselves. The aim of the current study is to examine associations between selected acoustic measures of speaking rate and listener ratings of speech naturalness in a group of adults who stutter following participation in an intensive fluency shaping treatment program.

Methods: Twenty-nine adults who stutter, drawn from an existing database of speech samples, served as participants. All participants had recently completed a four-week group-based intensive fluency shaping treatment program. …

Memory Support For Adults With Alzheimer’S Disease: Applications For Speech-Language Pathologists, Laura Dober

Honors Theses

Alzheimer’s disease (AD) is the most common form of dementia and is known to cause progressive and severely debilitating impairments in cognition, especially in memory. Deficits in memory and cognition are clearly reflected in the communication of people diagnosed with this progressive, degenerative, incurable disease, placing speech-language pathologists as important members of a care team for adults with AD. Speech-language pathologists provide treatment to support memory, and therefore communication, in people with AD through direct and indirect methods. Some examples of memory supportive strategies include spaced-retrieval learning, the use of external memory aids and assistive technology, Montessori methods, and manipulations …

Deficits In Sound Pattern Sequencing In Children With Specific Language Impairment: A Networks Approach, Sara J. Benham

Open Access Theses

Children with specific language impairment (SLI) demonstrate primary deficits in morphosyntax, which has served as the central theme in theoretical and clinical approaches. However, a striking number of children with SLI also exhibit speech sound deficits, characterized both by increased error patterns and by high levels of variability. These speech sound deficits have been under-studied and are not explicitly tied to accounts of SLI. In the present study, theoretical approaches drawn from dynamical systems and sequence learning are used to address speech production learning in children with SLI. Standard approaches to sound accuracy and variability and articulatory variability are integrated …

Neural Activity Reveals Effects Of Aging On Inhibitory Processes During Word Retrieval, Ranjini Mohan

Open Access Dissertations

Word retrieval difficulties are one of the most frustrating problems in older adults. Poorer access to phonological (speech sound) representation of the target word has been postulated as the underlying deficit, supported by findings of improvement in word retrieval after phonological priming. But the great variability in naming performance among older adults may reflect cognitive scaffolding or compensatory neurophysiological processes related to maintenance or decline of naming abilities. In order better understand aging effects in the underlying neurophysiological changes associated with phonological retrieval, the present study examined electrophysiological correlates of phonological priming and word retrieval in adults across the lifespan. …

Collaboration Occurring Between Professionals In Today's Schools, Kara Lynn Doglio

Theses and Dissertations

The collaborative service delivery model is beneficial in its approach as it allows educators and SLPs to work together to address communication impairments in naturalistic settings in order to maximize the functional potential of all students. The current utilization of collaboration as a viable service delivery option is unknown. The purpose of this study was to identify whether collaboration was occurring and with whom it was occurring. This study also sought to identify similarities and differences across four participant groups regarding perceived beliefs and reported practices in professional collaboration. While administrators took a separate survey than educators (general and special …

Understanding The Stigma Of Hearing Loss And How If Affects The Patient And Treatment Process, Carolyn M. Zaitzew

Williams Honors College, Honors Research Projects

This project is a literature review on the topic of hearing loss related stigma and the effects it has on persons with hearing loss. There has not been very much research conducted on this topic, which limited the paper’s content. Through researching and analyzing previous studies, it was found that a stigma related to hearing loss still exists today and has multiple effects on persons with hearing loss. The stigma can put negative stress on patients with hearing loss, both psychologically and socially, and may even cause them to not seek or accept treatment when needed. Younger adults are more …

An Investigation Of Motor Speech And Motor Limb Movements Following A Sport-Related Concussion-An Extension Study, Linda Phan

Open Access Theses & Dissertations

Background: Minimal research is available regarding the effects on motor speech and motor limb movements following a sport-related concussion (SRC). A sensitive measure is necessary to detect subtle deficits in motor speech, as it may provide diagnostic insight involving return-to- play decisions.

Purpose: This research aimed at replicating and extending a previous research study, Hewitt (2015), conducted at the University of Texas at El Paso. The Hewitt (2015) study examined motor speech tasks and motor limb tasks which included the following: oral diadochokinetics (DDK): sequential motion rate (SMR)(i.e. /puh-tuh-kuh/) and alternating motion rate (AMR) (i.e. /puhpuhpuh/, /tuhtuhtuh/, /kuhkuhkuh/); speech rate …

The Effect Of A Fluent Signing Narrator On Quality Of Maternal Behavior During E-Book Shared Reading Interactions With Their Children With Hearing Loss, Mar Alejandra Bonilla Yáñez

Open Access Theses & Dissertations

Purpose: The average high school student with hearing loss graduates reading at a 4th grade level. A factor that may contribute to the literacy development in children with typical hearing is language modeling and support surrounding shared book reading. The shared book reading experiences of children with hearing loss (CHL) and their parents may be different in quantity and quality from their peers with typical hearing. There is evidence reporting parental frustration and feeling of incompetence when reading to their CHL due to a sensory mismatch between the childâ??s and the parentâ??s mode of communication and skills. This study investigated …

The Effects Of Bilingualism On Auditory Selective Attention In Normal-Hearing Adults, Francisco Fernandez

Open Access Theses & Dissertations

Bilingual speakers have been shown to be more adept than monolingual speakers at actively blocking useless information in the visual modalities. This advantage should be observed in both the visual and the auditory modalities using tasks of inhibitory control. However, very little is known regarding how bilingualism influences inhibitory control in the perception of auditory information. By using an auditory test of inhibition, such as the utilization of a Dichotic Listening task, bilinguals are expected to display an increased measure of cognitive ability.
