The Effect Of Hearing Impairment On Word Processing Of Infant- And Adult-Directed Speech, Velma Sue Robertson

Theses and Dissertations (ETD)

Objective. Little is known about how children with hearing loss (CHL) process words. The Emergent Coalition Model (ECM) of early word learning proposes that multiple cues (e.g., perceptual, social, linguistic) are used to facilitate word learning. Because hearing loss influences speech perception, different word learning patterns may emerge in CHL relative to children with normal hearing (CNH). One perceptual cue used by young children to access word learning is infant-directed-speech (IDS). Specifically, twenty-one month-olds can learn words in IDS but not in adult directed speech (ADS); however, by 27 months children can learn words in ADS. Currently, it is unknown …

Mapping The Spatial And Temporal Dynamics Of Sensorimotor Integration During The Perception And Performance Of Wallowing, Megan E. Cuellar

Theses and Dissertations (ETD)

Similar to other complex sequences of muscle activity, swallowing relies heavily upon ‘sensorimotor integration.’ It is well known that the premotor cortex and primary sensorimotor cortices provide critical sensorimotor contributions that help control the strength and timing of swallowing muscle effectors. However, the temporal dynamics of sensorimotor integration remains unclear, even when performed normally without neurological compromise. Recent advances in EEG analysis blind source separation techniques via independent component analysis offer a novel and exciting opportunity to measure cortical sensorimotor activity in realtime during swallowing, concurrently with muscle activity during swallow initiation. In the current study, mu components were identified, …

Bilingual Language Assessment: Contemporary Practice Versus Recommended Practice, Graciela Arias

Theses and Dissertations

Due to the increasing number of culturally and linguistically diverse students within American school systems, speech-language pathologists (SLPs) in school settings must be prepared to distinguish between typically developing bilingual students and those with language impairments. The purpose of this study was to identify current practices of school-based SLPs for bilingual language assessment and compare them to both American Speech-Language-Hearing Association (ASHA) best practice guidelines, and mandates of the Individuals with Disabilities Education Act (IDEA). The study was modeled to replicate Caesar and Kohler's (2007) study to include a nationally representative sample. While the survey was opened over 400 times, …

Exploring Communication Apprehension And Its Relationship To Communication Attitude And Socio-Communicative Functioning In Children With Velopharyngeal Insufficiency, Agnieszka Dzioba

Electronic Thesis and Dissertation Repository

Myriad findings on children with velopharyngeal insufficiency (VPI) indicate the potential for this population of children to experience feelings of apprehension specific to communication and the potential for other psychological and social difficulties. The purpose of the present investigation was to explore the construct of communication apprehension (CA) and its potential relationship to social and communicative functioning in a diverse group of children with VPI. Potential linkages between CA and multiple socio-communicative constructs including attitude, speech satisfaction, speech and language skill, social competence, and speech severity were explored in a cohort of children with and without VPI, followed by an …

When Less Can Be More: Dual Task Effects In Stuttering And Fluent Adults, Naomi Nechama Eichorn

Dissertations, Theses, and Capstone Projects

The present study tested the counterintuitive hypothesis that engaging cognitive resources in a secondary task while speaking could benefit aspects of speech production. Effects of dual task conditions on speech fluency, rate, and error patterns were examined in stuttering and fluent speakers based on specific predictions derived from three related theoretical frameworks. Twenty fluent adults and 19 adults with confirmed diagnoses of stuttering participated in the study. All participants completed two baseline tasks: (1) a continuous speaking task in which spontaneous speech was produced in response to given prompts; and (2) a working memory (WM) task involving manipulations of WM …

Role Of The Cochlea And Efferent System In Children With Auditory Processing Disorder, Sriram Boothalingam

Electronic Thesis and Dissertation Repository

Auditory processing disorder (APD) is characterized by difficulty listening in noisy environments despite normal hearing thresholds. APD was previously thought to be restricted to deficits in the central auditory system. The current work sought to investigate brainstem and peripheral mechanisms that may contribute to difficulties in speech understanding in noise in children with suspected APD (sAPD). Three mechanisms in particular were investigated: cochlear tuning, efferent function, and spatial hearing. Cochlear tuning was measured using stimulus frequency otoacoustic emission (SFOAE) group delay. Results indicate that children suspected with APD have atypically sharp cochlear tuning, and reduced medial olivocochlear (MOC) functioning. Sharper-than-typical …

Evaluation Of Auditory Evoked Potentials As A Hearing Aid Outcome Measure, Vijayalakshmi Easwar

Electronic Thesis and Dissertation Repository

This thesis aimed to explore the applicability of Cortical Auditory Evoked Potentials (CAEPs) and Envelope Following Responses (EFRs) as objective aided outcome measures for use in infants wearing hearing aids. The goals for CAEP-related projects were to evaluate the effect of speech stimulus source on CAEPs, non-linear hearing aid processing on tone-evoked CAEPs, and the effect of inter-stimulus intervals on non-linear hearing aid processing of phonemes. Results illustrated larger amplitude CAEPs with shorter latencies for speech stimuli from word-medial positions than word-initial positions, and no significant effect of the tone burst onset overshoot due to non-linear hearing aid processing. Inter-stimulus …

The Effects Of Target Spectrum, Noise, And Reverberation On Auditory Cue Weighting In Sound Localization, Tran M. Nguyen

Electronic Thesis and Dissertation Repository

Sound localization in the horizontal plane depends on interaural time difference (ITD) and interaural level difference (ILD) cues, which are both available in wideband sounds. Previous studies have directly measured listener weighting of those cues only under quiet, anechoic conditions, but not in the presence of noise and reverberation, which can degrade both ITD and ILD. This study examined the effects of changes in target spectral profile, background noise, and reverberation on sound localization performance and cue weighting strategies. Listeners reported locations of targets that were presented over headphones in virtual auditory space. ITD and ILD were manipulated by attenuating …

Accuracy Of /T/ Productions In Children With Cochlear Implants As Compared To Normal-Hearing, Articulation Age-Matched Peers, Terry Gier

USF Tampa Graduate Theses and Dissertations

Children who receive cochlear implants (CIs) demonstrate considerable variability in speech sound production. Investigations focused on speech sound development in children with CIs have shown initial accelerated growth, followed by a plateau where consonant order of acquisition generally mirrors that of NH children, but is slower (Blamey, Barry, & Pascale, 2001; Serry & Blamey, 1999; Spencer & Guo, 2013). A notable exception to this pattern, /t/, has been shown to be acquired later-than normal in several investigations (Blamey et al., 2001; Chin, 2003; Ertmer, True Kloiber, Jongmin, Connell Kirleis, & Bradford, 2012). The primary purpose of this investigation was to …

The Effect Of Botulinum Toxin Type A On Speech Intelligibility In Oromandibular Dystonia, Beatriz Ysabel Domingo

Electronic Thesis and Dissertation Repository

Speech intelligibility of 10 individuals with OMD was measured before and after receiving BoNT-A injections. Intelligibility was assessed using the PIT (single-word intelligibility), SIT (sentence intelligibility), and a conversational speech task. Five listeners rated the speech intelligibility of these three intelligibility tasks via orthographic transcription and visual analogue scaling (VAS) techniques. BoNT-A was not associated with significant differences in speech intelligibility. Further analysis revealed a significant difference on the PIT VAS intelligibility ratings based on order of presentation, suggesting that listeners rated the first half of words on the PIT (words 1-29) as more intelligible than the second half of …

Spelling Of Derivationally Complex Words: The Role Of Phonological, Orthographic, And Morphological Features, Sofia Benson-Goldberg

USF Tampa Graduate Theses and Dissertations

Spelling ability is not static; rather, as children age, learning how to encode morphophonologically complex words in conventional ways is motivated by the increasingly complex demands imposed by academic experiences with morphologically complex words. Success requires ongoing integration of phonological (P), orthographic (O) and morphological (M) knowledge. However, current research on the development and assessment of spelling has not sufficiently accounted for the way word features and participant characteristics interact with students' POM knowledge in the spelling of derived words. This study used a linear mixed effects regression approach to provide new insights about how both word characteristics and students' …

Effect Of Retrieval Practice On Applied Knowledge: Evidence From A Professional Training Program, Jenna Voss

Arts & Sciences Electronic Theses and Dissertations

A primary goal of deaf education teacher preparation programs is to help students acquire a sufficient body of factual and pedagogical knowledge and retain it for future application while serving children with hearing loss and their families. One potential way to improve teacher preparation is through the implementation of retrieval practice, a strategy to promote learning and retention of material over time. This study examined whether retrieval practice could be used to improve learning in an authentic educational environment, using real content, and real materials. While this study provided important information regarding the implementation of retrieval practice authentic classrooms, it …

Language Skills, Oral Narrative Production, And Executive Functions Of Children Who Are Deaf Or Hard Of Hearing, Hyejin Park

Theses and Dissertations (ETD)

This study assessed the language skills, oral narrative abilities, and executive functions (EFs) of children who are deaf or hard of hearing (DHH) and normal hearing (NH), and examined the differences between two groups as well as the relationships between oral narrative production and EFs.

Eleven children who are DHH and ten who are NH, between 9 and 11 years of age, participated in the study. All of the children in the DHH group had bilateral hearing losses ranging from moderate through profound, and had no other diagnosed social, emotional or intellectual problems. All had more than 4 years 10 …

“Birth Order’S Effect On Language Delay Detection In Young Children”, Victoria C. Souhlas

Honors Theses

In the field of Speech-Language Pathology, research has shown that the earlier a child is diagnosed with a speech and language disorder, the better the prognosis is for a favorable therapy outcome (Carroll, Bowyer-Crane, Duff, Hulme, Snowling, 2011). This researcher concentrated on how the birth order of a child can affect the prognosis of a speech and language delay. For this study, the goal was to collect quantitative data in order to view the extent of the correlation between birth order and the age of diagnosis. A sample population was found at the DuBard School of Language Disorders at the …

Auditory Versus Cursive Writing Drills In Learning New Vocabulary In 4th Grade Children, Rachel S. Tyrone

Honors Theses

Vocabulary acquisition is fundamental in order for children to succeed not only academically, but also socially. Throughout the years, many scholars have researched various techniques to aid children in learning new vocabulary. Two of the techniques to aid vocabulary can be seen by utilizing an auditory and a writing technique. A teacher will present the students with several vocabulary words multiple times throughout a regular school year. These words are vital to the success of the child. Consequently, there is a need to discover a technique that will aid the students in learning the new vocabulary words. In order to …

The Relationship Between Speaking Rate And Nasalance In Typical Adult Speakers, Rachel Whitney

Masters Theses

Nasometry is a non-invasive tool frequently used to measure speech resonance in clinical populations. The instrument uses an acoustic recording system to derive a measure termed nasalance, which is an estimate of the relative amount of acoustic energy emitted from the nasal cavity. Nasometry protocols do not provide detailed instructions for speaking rate control during data collection. Studies attempting to establish a relationship between speaking rate and nasalance have yielded mixed results; therefore, it is important to identify the influence of speaking rate on nasalance in a variety of speaking tasks. If rate is found to influence nasalance values, protocols …

The Effect Of Metalinguistic Strategy Instruction On The Oral And Written Expression Of School-Aged Children, Karen Lara Dudek

Theses and Dissertations

Vocabulary knowledge is critical for academic success; and research has indicated that students with low vocabularies can learn metalinguistic strategies that can improve their performance in school. In this study, I investigated the impact of metalinguistic strategy instruction on the oral and written expression abilities of elementary-aged children (third grade). The strategy was the Expanding Expression Tool (EET; Smith), which can help students to increase their oral and written expression by describing words using semantic features. I used a pretest-posttest-posttest between groups design to investigate the impact of three experimental conditions on oral and written expression over a nine week …

Plastic Effect Of Tetanic Stimulation On Auditory Evoked Potentials, Rajesh Tripathy

Electronic Thesis and Dissertation Repository

The goal of this thesis was to investigate tetanic acoustic stimulation (TS) and its effects on the human auditory system. Two experiments were completed to study the effects of a 2 minute duration 1 kHz TS on the auditory brainstem and cortex using auditory evoked potentials. At the cortical level the auditory long latency response (ALLR) was recorded and the P1, N1, and P2 components were measured; in the brainstem the amplitude of the 80 Hz auditory steady state response (ASSR) was measured. TS induced significant changes in ALLR component latencies, and a significant reduction in ASSR amplitude, but these …

The Influence Of Gestural Learning On Oral Reading And Reading Comprehension, Rachael Joymarie Williams

Wayne State University Theses

The purpose of this study is to evaluate how gestural training may facilitate oral reading and reading comprehension of single words. For example, it is not clear whether multi-modal cues such as gesture provide an advantage over verbal cueing alone, or which type of multi-modal cues may be more effective than others in visual-verbal learning. This study examined language learning in healthy volunteers to be able to apply the effective methods for language intervention in individuals with language difficulties.

Thirty-two healthy adults were selected to participate in four different learning conditions including verbal alone, visual cue, meaningful gesture, and meaningless …

Potential Influences Of Compliance For Short-Term Recovery From Sports-Related Concussion, Erin R. Ewing

Open Access Theses & Dissertations

Currently, treatment of sports-related concussion dictates the prescription of physical and cognitive rest to allow the injured brain to recover and for concussion-related symptoms to subside. However, clinicians who prescribe rest are often met with resistance from athletes who do not recognize its therapeutic value in the recovery process. Research has shown that athletes often fail to comply with rest recommendations, resulting in protracted recovery and the persistence of symptoms. Method: This study employed a three-group pretest-posttest experimental design to compare the effects of three different concussion management protocols. Participants were recently concussed athletes ages 18-25 seen in the UTEP …

Nonword Repetition Performance Patterns In English - Spanish Bilingual Adults And English And Spanish Monolingual Adults, Nadia Arriazola Flores

Open Access Theses & Dissertations

Nonword repetition (NWR) is known to be a less biased measure for assessing language abilities of culturally and linguistically diverse (CLD) children (Dollaghan & Campbell, 1998). NWR is used to examine phonological short-term memory mechanisms (also called working memory), because the tasks require the capability to discriminate, store, remember and reproduce phonological sequences (Baddeley, 1989; Braddeley 1974). The purpose of this study was to collect normative data on the NWR performance of bilingual and monolingual adults. This may contribute to the interpretation of performance in bilingual children by providing the standard of adult-like performance. This study examined the performance patterns …

A Pilot Study: Examining The Microstructural And Macrostructural Narrative Measures In Bilingual Preschool Aged Children, Caroline Esparza

Open Access Theses & Dissertations

Purpose: Research has identified narratives as accurate and reliable predictors of language skills, yet little is documented on the microstructural and macrostructural narrative production of preschool aged bilingual children. This pilot study examined the microstructure and macrostructure elements of narratives in these children to provide preliminary data for further research.

Method: This study examined the narrative skills of 11 bilingual children between the ages of 3 and 4. Narrative retells in Spanish were elicited and were analyzed for the microstructural measures of lexical diversity (NDW) and productivity (TNW and MLU) measures and for the their macrostructural Narrative Scoring Scheme (NSS) …

The Effects Of Cognates On Receptive And Expressive Language Among Typically Developing Preschool Second Language-Learners, Jesica B. Zavala De Guerrero

Open Access Theses & Dissertations

This exploratory study considers the facilitating effects of cognates across language of intervention, seeking to assess potential cross-language generalizations among typically developing preschool bilinguals. Nine bilingual, English-Spanish speakers of preschool age were assigned to one of three experimental groups (an English only group, a Spanish only group, and a bilingual group) or to a control condition. Children in the experimental groups were introduced to a vocabulary intervention that incorporated cognates and non-cognates. Analysis of data suggests the absence of a cognate advantage among preschool age children; furthermore limiting any possible cross-language generalizations. It is plausible to suspect that age may …

Services And Information Provided To Mothers In El Paso/Juarez Region, Christina Y. Perez

Open Access Theses & Dissertations

It is estimated that the Latino population will be the majority of the population by 2050 in the United States. There is research supporting the notion that the Latino population is under-served and under-diagnosed regarding physical and mental illnesses. Appropriately informed professionals and parents are the first step to reducing the number of under-diagnosed children that do not receive the treatment they require. This survey was conducted to determine what information Latino mothers from low socio-economic backgrounds possess concerning the developmental milestones of their children and the services available to them. Fifty mothers responded to the survey. Results revealed that …

Cochlear Development And Auditory Function In The Absence Of Thyroid Hormone Transporters Mct8 And Oatp1c1, Richard Sinn

All Graduate Theses, Dissertations, and Other Capstone Projects

Thyroid hormone (TH) is essential for the development and maturation of the nervous system. The thyroid gland secretes an active form of TH, triiodothyronine, and a prohormone, thyroxine, into the blood. TH is charged, which prevents it from passively diffusing across cell membranes and thus requires cell membrane transporters to facilitate its movement into and out of cells. However, whether TH transporters are required for TH-mediated developmental events, including the auditory system, is largely unknown.

The purpose of the present study was to investigate two specific TH transporters, monocarboxylate transporter 8 (Mct8) and organic anion transporting polypeptide 1c1 (Oatp1c1), and …

Speech And Swallowing Rehabilitation In The Home: A Comparison Of Two Service Delivery Models For Stroke Survivors, Katy J. E. Stewart

Theses: Doctorates and Masters

Background and Aims

Speech and swallowing difficulties are common sequelae for people who have suffered a stroke. Recently, there has been an increase in early discharge, community rehabilitation and the use of therapy assistants to support health professionals in stroke rehabilitation. However, the impact of these factors on communication and swallowing outcomes remains under researched. This research explored Rehabilitation in the Home (RITH) Speech Pathology (SP) services for stroke survivors with dysarthria and dysphagia. More specifically, this research investigated whether traditional speech pathology interventions, supplemented with a home practice program are effective, as well as compare usual treatment to that …
