Effects Of Aging And Spectral Shaping On The Sub-Cortical (Brainstem) Differentiation Of Contrastive Stop Consonants, Dania A. Rishiq

Theses and Dissertations (ETD)

Purpose: The objectives of this dissertation are to: (1) evaluate the influence of aging on the sub-cortical (brainstem) differentiation of voiced stop consonants (i.e. /b-d-g/); (2) determine whether potential aging deficits at the brainstem level influence behavioral identification of the /b-d-g/ stimuli, (3) investigate whether spectral shaping diminishes any aging impairments at the brainstem level; and (4) if so, whether minimizing these deficits improves the behavioral identification of the speech stimuli.

Subjects: Behavioral and electrophysiological responses were collected from 11 older adults (> 50 years old) with near-normal to normal hearing and were compared to those of 16 normal-hearing younger …

Modeling Hrtf For Sound Localization In Normal Listeners And Bilateral Cochlear Implant Users, Douglas A. Miller

Electronic Theses and Dissertations

Mathematical models can be very useful for understanding complicated systems and for testing algorithms through simulation that would be difficult or expensive to implement. This dissertation presents a model that attempts to simulate the sound localization performance of persons using bilateral cochlear implants. The expectation is that this model could prove to be a useful tool in developing new signal processing algorithms for neural encoding strategies.

The head related transfer function (HRTF) is a critical component of this model, and in the ideal case, provides the base characteristics of head shadow, torso and pinna effects. This defines the temporal, intensity …

Time-Frequency Analysis Of Transient-Evoked Otoacoustic Emissions In Children Exposed To Carboplatin Chemotherapy, Shaum Bhagat, Johnnie Bass, Ibrahim Qaddoumi, Rachel Brennan, Matthew Wilson, Jianrong Wu, Carlos-Rodriguez Galindo, Alessia Paglialonga, Gabriella Tognola

Faculty Publications

The aims of this study were to characterize and quantify time-frequency changes in transient-evoked otoacoustic emissions (TEOAEs) recorded in children diagnosed with retinoblastoma who were receiving carboplatin chemotherapy. A signal processing technique, the wavelet transform (WT), was used to analyze TEOAE waveforms in narrow-band frequency components. Ten children (aged 3–72 months) diagnosed with unilateral or bilateral retinoblastoma were enrolled in the study. TEOAEs were acquired from the children with linear sequences of 70 dB peak equivalent SPL clicks. After WT analysis, TEOAE energy, latency and normalized energy in the narrow-band frequency components were compared before and during carboplatin chemotherapy treatment …

Syllabic Patterns In The Early Vocalizations Of Quichua Children, Christina E. Gildersleeve-Neumann, Barbara L. Davis, Peter F. Macneilage

Speech and Hearing Sciences Faculty Publications and Presentations

To understand the interactions between production patterns common to children regardless of language environment and the early appearance of production effects based on perceptual learning from the ambient language requires the study of languages with diverse phonological properties. Few studies have evaluated early phonological acquisition patterns of children in non-Indo-European language environments. In the current study, across- and within-syllable consonant-vowel co-occurrence patterns in babbling were analyzed for a 6-month period for seven Ecuadorean Quichua learning children who were between 9 and 17 months of age at study onset. Their babbling utterances were compared to the babbling of six English-learning children …

Facilitation Of Language Acquisition Viewed Through An Interpretative Lens: The Role Of Authenticity, Melanie Ann Harper

Wayne State University Dissertations

A paradigm is the conceptual framework or lens one uses to view reality. The field of speech-language pathology is traditionally rooted in the empirical paradigm, which believes that language can be fragmented into isolated skills and taught in a hierarchal fashion. This belief has resulted in service delivery models that remove students from naturalistic contexts for decontextualized exercises. Progress in language acquisition is measured objectively. The empirical belief is exemplified by the accountability requirements in special education law (e.g., IEP). It is compounded by the realities of public school speech-language pathologists (SLPs), such as high caseload numbers, multiple buildings, and …

Age-Related Changes To The Production Of Linguistic Prosody, Daniel Richard Barnes

Open Access Theses

The production of speech prosody (the rhythm, pausing, and intonation associated with natural speech) is critical to effective communication. The current study investigated the impact of age-related changes to physiology and cognition in relation to the production of two types of linguistic prosody: lexical stress and the disambiguation of syntactically ambiguous utterances. Analyses of the acoustic correlates of stress: speech intensity (or sound-pressure level; SPL), fundamental frequency (F0), key word/phrase duration, and pause duration revealed that both young and older adults effectively use these acoustic features to signal linguistic prosody, although the relative weighting of cues differed by group. Differences …

Preschool Language And Phonological Proficiencies In Predicting Stuttering Recovery Or Persistence, Caroline E. Spencer

Open Access Theses

The purpose of this study was to investigate the relationship between expressive and receptive language, phonological, and verbal working memory proficiencies in the preschool years and eventual recovery from or persistence in stuttering. Participants included 40 children who stutter (CWS). At ages 3-5 years, participants were administered the Test of Auditory Comprehension of Language, 3rd edition (TACL-3), the Structured Photographic Expressive Language Test, 3rd edition (SPELT-3), Bankson-Bernthal Test of Phonology--Consonant Inventory subtest (BBTOP--CI), Test of Auditory Perceptual Skills--Revised (TAPS--R) auditory number memory and auditory word memory subtests, and the Dollaghan & Campbell Nonword Repetition Test (NRT). Stuttering behaviors were tracked …

Self-Ratings Of Communication Style And Discourse Performance Of Healthy Aging Adults, Hayley E. Besten

Theses and Dissertations--Communication Sciences and Disorders

This study investigated the accuracy of healthy aging adults‟ self-rating of communication style, as measured by quantifiable measures of discourse performance. Ninety cognitively healthy adults participated and comprised three age cohorts (20s, 40s, 60s). Participants completed discourse tasks that included recounting a vacation, telling a story, and describing a picture. Participants also self-rated their communication style, placing them in a talkative or reserved cohort. Communication style was measured by discourse performance variables of interest: length of output (TNW) and informativeness (%IU). When presented with an unconstrained task (recounting a vacation), talkative and reserved groups, regardless of age, produced a similar …

Structural Processing Of Language Components: Detection And Comprehension, Samantha Rose Crow

Wayne State University Theses

Although music and language share many perceptually functional characteristics, research endeavors are still focusing on the underlying neural circuitry. Past research has indicated a distinction of hemispheric lateralization between music and language processing. Recently, efforts have shifted to the notion of an initial general shared pathway in the brain with auditory stimuli differentiated in later processing to specialized regions. Therefore, both linguistic and musical components have been examined in numerous experiments to discern the possible influence of music and language components on auditory perception and comprehension, including their potential interaction. However, the effects of sentential prosody on early language structural …

Supporting Speech-Language Pathologist Evidence-Based Practice Use: A Mixed-Methods Study In Skilled Nursing Facilities Within The Promoting Action On Research Implementation In Health Services Framework, Natalie Franko Douglas

USF Tampa Graduate Theses and Dissertations

As the management of dementia is a significant public health concern, efforts to increase access to effective treatments to a greater number of residents with dementia in skilled nursing facilities (SNFs) are warranted. The treatment addressed in this study, non-electronic external memory aids, is an evidence-based practice that has been found to increase positive communicative interactions and decrease negative behavioral problems of residents with dementia in SNFs.

Although use of memory aids is recommended, there are significant barriers such as lack of time and resources that inhibit the use of effective treatments in typical clinical settings. To address such barriers …

Does The Use Of Personally Relevant Stimuli In Semantic Complexity Training Facilitate Improved Functional Communication Performance Compared To Non-Personally Relevant Stimulus Items Among Adults With Chronic Aphasia?, Stephanie Karidas

USF Tampa Graduate Theses and Dissertations

This study investigated the influence of semantic complexity treatment in individuals with fluent aphasia on discourse performance. Semantic treatment is an effective way to improve semantically based word retrieval problems in aphasia. Treatment focused on the semantic application of the Complexity Account of Treatment Efficacy (CATE) (Thompson, Shapiro, Kiran, & Sobecks, 2003) promotes training of complex items resulting in generalization to less complex, untrained items. In addition, research has shown that the personal relevance of treatment material can increase treatment efficacy. This study investigated the effect of semantic treatment of atypical personally relevant items among individuals with aphasia on discourse …

The Effect Of Rate Change On The Relative Timing Of Speakers With Multiple Sclerosis, Brandlynn N. Reister

USF Tampa Graduate Theses and Dissertations

Relative timing ratios are a useful measure for determining the temporal regularities of speech. The timing intervals that make up these ratios are thought to be important when creating the motor plan for an utterance (Weismer & Fennell, 1985). In fact, these ratios have been shown to be remarkably stable, even when speakers deliberately increase their rate (Tuller & Kelso, 1984; Weismer & Fennell, 1985). The constancy of these ratios also has been demonstrated in speakers with known speech timing disturbances, like the dysarthrias associated with Parkinson's and Huntington's disease (Goberman & McMillan; Ludlow, Connor, & Bassich, 1987; Weismer & …

Nonword Processing In Bilingual Five Year Olds: Do Phonotactics Count?, Kyna Betancourt

USF Tampa Graduate Theses and Dissertations

Phonotactic processing is foundational to the word processing task in both monolingual and bilingual children (Li & Farkas, 2002; Pierrehumbert, 2001; Shook & Marian, 2013; Storkel & Morrisette, 2002). While the use of phonotactic information in word processing in monolingual children is relatively well documented, it is less well understood in bilingual children. The purpose of this study was to investigate how bilingual kindergartners process the phonotactic probabilities of their two languages. A set of nonwords was developed that manipulated the strength of phonotactic probability across both Spanish and English while also controlling the language environment of the experimental task …

Brain Electrophysiological Correlates Of Masked Picture Priming In Fluent And Stuttering Adults, Kalie B. Morris

USF Tampa Graduate Theses and Dissertations

Abstract

Objective: The aim of the present study was to investigate mechanisms of real-time language production of adults who stutter.

Method: Data were analyzed for 19 typically fluent young adults (TFA) and 19 young adults who stutter (AWS). Participants performed a masked picture priming task where priming stimuli consisted of two conditions 1) Identity- a masked printed prime word identical to the picture target label, and 2) Unrelated- a masked printed prime word unrelated to the picture target label. Brain event-related potentials (ERPs), time-locked to pictures eliciting spontaneous naming, were recorded, as well as naming accuracy and reaction times.

Results: …

Supporting Narrative Retells For People With Aphasia Using Aac: Photographs Or Line Drawings? Text Or No Text?, Julie Griffith, Aimee R. Dietz, Kristy S.E. Weissling

Department of Special Education and Communication Disorders: Faculty Publications

People with aphasia (PWAs) have demonstrated the ability to learn augmentative and alternative communication (AAC) devices that employ traditional grid layouts to enhance their communication; however, the process is typically lengthy and yields limited generalization (Fox & Fried-Oken, 2001; Koul & Harding, 1998). In response, researchers have begun to investigate the use of visual scene displays (VSDs) to support the communication interactions of PWAs by capitalizing on their relatively intact episodic memory (Beukelman, Dietz, McKelvey, Hux, & Weissling, in press; Dietz, Beukelman, & McKelvey, 2006a; Dietz, McKelvey, Beukelman, Weissling, & Hux, 2006b; McKelvey, Dietz, Hux, Weissling, & Beukelman, 2007). High-technology …

Evaluation Of Language Of Intervention On Expressive-Receptive Lexical Skills For Preschool Bilingual Children, Blanca Estela Cisneros

Open Access Theses & Dissertations

The purpose of the study was to evaluate the expressive-receptive lexical skills gained in bilingual preschool children for both their native language (L1) and second language (L2) when provided a bilingual vocabulary intervention and compared to contrasting monolingual and controlled conditions. This group study assessed four treatment conditions: monolingual English intervention, monolingual Spanish intervention, bilingual English-Spanish intervention, and a controlled intervention condition receiving math instruction. English and Spanish expressive and receptive lexical skills were the dependent variables measured at pretest and posttest. After a brief 4 week intervention block, the bilingual group achieved greater gains in Spanish expressive lexical skills …

Examining Articulatory Kinematics Using Diadochokinesis In Concussed And Non-Concussed Individuals, Lindsay Deann Dolan

Open Access Theses & Dissertations

ABSTRACT

Cognitive and communicative deficits associated with traumatic brain injury are an active area of research. However, no research to date has reported on the functionality of motor speech following a concussion. A common tool used to evaluate the motor speech status of potentially impaired individuals is the measurement of the diadochokinetic speech rate. The purpose of this study is to investigate diadochokinetic speech rates in individuals who experience a sports-related concussion. Determining the nature and extent of motor speech involvement post concussion will contribute to the diagnosis, prognosis, and management of recovery. The present investigation will determine; (i) if …

Language Of Intervention In Bilingual Children With Autism Spectrum Disorder, Alejandra Carrillo

Open Access Theses & Dissertations

Over the last few decades the United States has seen a heavy increase in the incidences of Autism Spectrum Disorder. Also increasing in the United States is the increase in multicultural and multilingual groups. Although both of these populations are increasing there is very limited information regarding the language abilities of bilingual individuals with Autism Spectrum Disorder, the language used for intervention, and those servicing them. A survey was developed to gather information regarding the current practice trends used by Speech-Language clinicians with bilingual children with ASD. The study was conducted in El Paso, Texas a city located on the …

Benefits Of Baby Sign On Cognitive Development In Infants, Clarissa Navedo

Open Access Theses & Dissertations

Research in the area of baby sign language has increased dramatically over the past several years, however there is still a lack of research regarding baby signs effects on typical infant development, specifically in the area of cognition. The hypothesis of this study was that instruction of baby sign would be correlated with a significant increase in the development of cognition and language acquisition for infant participants. This study provided a five-week instructional course on baby sign for parents/caregivers to implement with their typically developing infants (n=11). The course provided instruction of baby signs, methods of implementation and encouragement to …
