Effects Of External Memory Aid Assessment And Treatment On Everyday Task Performance Of Individuals With Mild Neurocognitive Disorder, Alyssa M. Lanzi

USF Tampa Graduate Theses and Dissertations

Individuals with mild neurocognitive disorder complete many activities of daily living independently; however, they may require the use of compensatory strategies while performing everyday tasks. Compensatory strategies, such as external memory aids, incorporate a strengths-based approach to enhance the functional needs of individuals. Although external memory aids have a strong evidence-base, limited assessment tools and interventions are available to facilitate the development of individualized treatment plans that promote sustained strategy use. To better support the everyday needs of individuals with mild neurocognitive disorder and to inform clinicians who are developing interventions, the current dissertation includes four paper that examine a …

Factors Related To Hearing Aid Use Among Older Adults From Hispanic/Latino Backgrounds: Findings From The Hispanic Community Health Study/Study Of Latinos, Michelle L. Arnold

USF Tampa Graduate Theses and Dissertations

The purpose of this dissertation was to understand perceived hearing loss and hearing health care use among older adults from Hispanic/Latino backgrounds using the Andersen model of health care utilization as a framework. A cross sectional analysis of audiometric and survey data from the Hispanic Community Health Study/Study of Latinos was used to estimate factors that characterize perceived hearing handicap and hearing aid use, and to determine hearing aid use rates in a large group of older Hispanic/Latino adults. Data came from 6970 adults aged 45 to 76. Results revealed that self-perceived hearing handicap is significantly correlated to measured hearing …

Early Literacy Abilities In Spanish-English Emergent Bilingual Children From Varied Dialectal Backgrounds, Antonietta Mastrota

USF Tampa Graduate Theses and Dissertations

The Hispanic population within the United States has grown to a considerable amount. The state of Florida’s population is 25% Hispanic, with projected estimates of this population continuing to grow in the coming years (Ortman & Shin, 2011). Statistics show that 28.3% of the state’s population, over the age of five, speak a language other than English at home. With this considerable number of Spanish-speakers comes the responsibility to adjust certain educational practices to best meet their needs. Literacy is an essential part of learning, and therefore assessing early literacy is an essential part to any child’s academic development.

Phonological …

Validity Of A Dynamic Spanish Assessment Of Phonological Awareness In Emergent Bilingual Children, Kelsey R. Wyman Chin

USF Tampa Graduate Theses and Dissertations

Within the current decade, the number of Hispanic students has doubled so that about 16% of the total student population within the United States are Spanish-speakers (U.S. Census Bureau, 2017). With this growing population comes a responsibility to understand and implement best practices for educating these students. Because literacy is a building-block for learning, one integral part of this responsibility consists of developing valid and reliable means of assessing pre-reading skills that are predictive of later reading abilities (Lonigan, Burgess, & Anthony, 2000; Wagner, Torgesen, & Rashotte, 1994).

English-language learning children are being identified for having reading difficulties and disabilities …

Articulatory Patterns In Children Who Use Cochlear Implants: An Ultrasound Measure Of Velar Stop Production In Bilingual Speakers, Katherine Javier

USF Tampa Graduate Theses and Dissertations

Coarticulation occurs in running speech when one speech sound or phoneme overlaps with another. It can be considered a result of the way we sequence and organize our articulators to efficiently produce consecutive consonants and vowels in fluent speech. Previous research has suggested that measures of coarticulation can provide insight into the maturity of the motor speech planning system (Barbier, Perrier, Ménard, Payan, Tiede, & Perkell, 2013; Zharkova & Hewlett, 2009; Zharkova, Hewlett, & Hardcastle, 2011). Speech stability has also been suggested as an indicator of motor speech maturity in previous research using ultrasound imaging of velar-vowel targets (Frisch, Maxfield, …

Relationship Between Intelligibility And Response Accuracy Of The Amazon Echo In Individuals With Amyotrophic Lateral Sclerosis Exhibiting Mild-Moderate Dysarthria, Caroline A. Layden

USF Tampa Graduate Theses and Dissertations

There is an ever-growing and increasing amount of technology options that use speech recognition software. Currently, the market includes smartphones, computers, and individual smart home personal assistants that allow for hands-free access to this technology. Research studies have explored the utility of these assistive devices for the completion of activities of daily living; however, there is limited research looking at the accuracy of voice recognition software within smart home personal assistants in populations with disordered speech. In persons with amyotrophic lateral sclerosis (ALS), symptoms include changes to motor functions, speech in particular, and it is unknown how some of these …

The Impact Of Vocabulary Knowledge On Nonword Judgments In Spanish-English Bilinguals, Marisa E. Leyden

USF Tampa Graduate Theses and Dissertations

This thesis suggests that the range of vocabulary in an individual’s lexicon has an influence on in their assessment of nonword wordlikeness. The study included thirteen Spanish-English bilinguals who participated in a language dominance questionnaire, standardized assessments of Spanish and English vocabulary knowledge, and Spanish and English wordlikeness judgment tasks. Resulting data demonstrated moderate correlations between vocabulary knowledge and performance on nonword wordlikeness judgement tasks in Spanish and English. Participants with larger lexicons appeared more tolerant of less probable nonwords, those with low phonotactic probability, while those with smaller lexicons were less accepting of nonwords with low phonotactic probability. The …

Relationship Between Vocal Fatigue And Physical/Psychological Factors In Prospective Vocal Professionals, Camille C. Gray

USF Tampa Graduate Theses and Dissertations

Background: To date, research has primarily focused on the subjective and objective measurement of vocal fatigue in professional voice users such as teachers and singers. However, these studies have not examined the effects of psychosocial factors (e.g., lack of sleep, emotional distress) leading to vocal fatigue in depth. Much like the professional voice users, students seeking to be professional voice users may face several psychosocial difficulties, may also experience similar vocal demands, and may develop vocal fatigue.

Goal: The purpose of this study is to identify the relationship between psychosocial factors and vocal fatigue in students majoring in Communication Sciences …

Perceptual And Physiologic Analysis Of Dystussia In Amyotrophic Lateral Sclerosis, Stephanie Anne Watts

USF Tampa Graduate Theses and Dissertations

Swallowing and cough are two vital functions that are reflexive in nature and are related to each other in terms of shared neural and anatomical space. When a disorder impacts normal and effective swallowing and/or cough, the consequences can be life-threatening. Evaluation and treatment of swallowing and cough disorders can fall under the scope of practice of the speech-language pathologist and speech-language pathologists often are leading professionals. Furthermore, much of the current research on swallowing and cough is spearheaded by speech-language pathologists often working with a multi-disciplinary team. The focus of this dissertation is on the clinical evaluation of cough …

Neural And Behavioral Mechanisms Of Clear Speech, Jenna Silver Luque

USF Tampa Graduate Theses and Dissertations

Clear speech is a speaking style that has been shown to improve intelligibility in adverse listening conditions, for various listener and talker populations. Clear-speech phonetic enhancements include a slowed speech rate, expanded vowel space, and expanded pitch range. Although clear-speech phonetic enhancements have been demonstrated across a variety of talkers, only a subset of these changes may be required for listeners to benefit perceptually from clear speech. Furthermore, while current literature has provided some understanding of the phonetic enhancements that are typical of clear speech and the improvements in intelligibility resulting from its use, less is understood regarding how listeners …

Selection Of Memory Book Content: Agreement In Content As A Function Of Informant Relationship To Memory Book Recipient, Rebecca J. Allen

USF Tampa Graduate Theses and Dissertations

This study was designed to determine to what extent provision of personally relevant information and sensory cues would agree between Recipient and Informant for selection of memory book content. Six dyads married to each other an average of 29.17 years (SD = 10.03), between the ages of 43 and 70 years (Mean = 57; SD = 8.39), and cognitively competent (i.e., no diagnosis of cognitive impairment) participated. Participants completed questionnaires independently and provided personally relevant information/memories, aversions towards select memories/topics, and sensory cues on behalf of themselves (as “Recipient) and their spouse (as “Informant”). For provision of personally relevant information/memories, …

Perceptual Differences In Natural Speech And Personalized Synthetic Speech, Katherine Overton

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to determine what perceptual differences existed between a natural recorded human voice and a synthetic voice that was created to sound like the same voice. This process was meant to mimic the differences between a voice that would be used for Message Banking and a voice that would be created by the ModelTalker system. Forty speech pathology graduate students (mean age = 23 years) rated voices on clarity, naturalness, pleasantness, and overall similarity. Analysis of data showed that the natural human voice was consistently rated as more natural, clear, and pleasant. In addition, participants …

Validity Of A New Measure Of Phonemic Awareness That Does Not Require Spoken Responses In Children With Complex Communication Needs, Tiffany Chavers

USF Tampa Graduate Theses and Dissertations

Children with complex communication needs (CCN) routinely have difficulty attaining appropriate literacy skills. Two indicators of literacy development are the alphabetic principle and phonemic awareness (Byrne & Fielding-Barnsley, 1989). The acquisition of minimal literacy skills such as letter sound knowledge can give children with CCN the opportunity to communicate and generate their own messages, instead of being reliant on vocabulary provided by others. In order to identify appropriate intervention approaches, nonverbal assessments of phonological and phonemic awareness for individuals with CCN are needed.

The purpose of this study was to determine the reliability of the Dynamic Assessment of the Alphabetic …

The Effect Of Clinical Experience On Perceived And Self-Reported Empathy In Novice Speech- Language Pathology Clinicians, Erline Vieira Nakano

USF Tampa Graduate Theses and Dissertations

In the field of medicine, empathic providers have been found to bring numerous benefits to a clinical encounter as they are better able to elicit detailed and thorough case histories, build rapport and therapeutic alliance with patients, and foster greater compliance with treatment recommendations. Despite its multiple benefits, empathy has not been researched systematically within the field of speech-language pathology. In medical training, empathy has been found to decline by the time medical students are introduced to direct patient care. Currently, no information is available regarding the empathy trajectory of novice speech-language pathologists.

The goal of the current project was …

Recovery From Diffuse Brain Injuries: Two Case Studies., Alejandro E. Brice, Roanne G. Brice

USF St. Petersburg Campus Faculty Publications

Subarachnoid hemorrhages (SAHs) are grave medical emergencies, whereas 30–50% of all SAHs may ultimately result in death. Subarachnoid hemorrhages share many resemblances with other neurological traumas such as a cerebral vascular accident, meningitis, and/or traumatic brain injury. Autoimmune encephalopathies (AE) occur when human antibodies assault the body’s cell surfaces and/or synaptic proteins. Consequently, widespread nervous system and diffuse brain involvement may occur. With subarachnoid hemorrhages and autoimmune encephalopathies, multiple areas of cognition and language can be impaired. Case studies in communication sciences and disorders are underutilized, yet are important in evidenced‐based practice. Speech-language pathologists in medical settings have worked with …

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 …

Discriminability And Perceptual Saliency Of Temporal And Spectral Cues For Final Fricative Consonant Voicing In Simulated Cochlear-Implant And Bimodal Hearing, Ying-Yee Kong, Matthew B. Winn, Katja Poelmann, Gail S. Donaldson

Communication Sciences and Disorders Faculty Publications

Multiple redundant acoustic cues can contribute to the perception of a single phonemic contrast. This study investigated the effect of spectral degradation on the discriminability and perceptual saliency of acoustic cues for identification of word-final fricative voicing in “loss” versus “laws”, and possible changes that occurred when low-frequency acoustic cues were restored. Three acoustic cues that contribute to the word-final /s/-/z/ contrast (first formant frequency [F1] offset, vowel–consonant duration ratio, and consonant voicing duration) were systematically varied in synthesized words. A discrimination task measured listeners’ ability to discriminate differences among stimuli within a single cue dimension. A categorization task examined …

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 …

Large Cross-Sectional Study Of Presbycusis Reveals Rapid Progressive Decline In Auditory Temporal Acuity, Erol J. Ozmeral, Ann C. Eddins, Robert Frisina Sr., David A. Eddins

Communication Sciences and Disorders Faculty Publications

The auditory system relies on extraordinarily precise timing cues for the accurate perception of speech, music, and object identification. Epidemiological research has documented the age-related progressive decline in hearing sensitivity that is known to be a major health concern for the elderly. Although smaller investigations indicate that auditory temporal processing also declines with age, such measures have not been included in larger studies. Temporal gap detection thresholds (TGDTs; an index of auditory temporal resolution) measured in 1071 listeners (aged 18–98 years) were shown to decline at a minimum rate of 1.05 ms (15%) per decade. Age was a significant predictor …

Construction And Evaluation Of Rodent-Specific Rtms Coils, Alexander D. Tang, Andrea S. Lowe, Andrew R. Garrett, Robert Woodward, William Bennett, Alison J. Canty, Michael I. Garry, Mark R. Hinder, Jeffery J. Summers, Roman Gersner, Alexander Rotenberg, Gary Thickbroom, Joseph P. Walton, Jennifer Rodger

Communication Sciences and Disorders Faculty Publications

Rodent models of transcranial magnetic stimulation (TMS) play a crucial role in aiding the understanding of the cellular and molecular mechanisms underlying TMS induced plasticity. Rodent-specific TMS have previously been used to deliver focal stimulation at the cost of stimulus intensity (12 mT). Here we describe two novel TMS coils designed to deliver repetitive TMS (rTMS) at greater stimulation intensities whilst maintaining spatial resolution. Two circular coils (8 mm outer diameter) were constructed with either an air or pure iron-core. Peak magnetic field strength for the air and iron-cores were 90 and 120 mT, respectively, with the iron-core coil exhibiting …

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 …

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 …

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 …

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) …

Assessing Excessive Noise Exposure Of Music-Oriented Nightclub Employees, Aiyanna Fitzgerald

USF Tampa Graduate Theses and Dissertations

Much research has gone into noise-induced hearing loss (NIHL) and the effects of high intensity noise levels on the hearing mechanism of individuals. A study by the National Institutes of Health has established that high intensity sounds can cause hearing damage of either a temporary, or worse, a permanent nature; regardless of the age of the person. While sound levels below 75 decibels are considered comparatively harmless and have been found not to cause any kind of permanent hearing loss; sound levels greater than 85 decibels and regular exposure of approximately 8 hours per day, on an average, has been …

Systematic Replication Of The Effects Of A Supplementary, Technology-Assisted, Storybook Intervention For Preschool Children With Weak Vocabulary And Comprehension Skills, Charles R. Greenwood, Judith J. Carta, Elizabeth S. Kelley, Gabriela Guerrero, Na Young Kong, Jane Atwater, Howard Goldstein

Communication Sciences and Disorders Faculty Publications

In 2013, Spencer, Goldstein, Sherman, et al. reported the promising effects of a supplemental, technology-assisted, storybook intervention (Tier 2) containing embedded instruction targeting the oral language learning of preschool children at risk for delays. We sought to advance knowledge of the intervention by replicating it in a new sample and examining children’s responses to the narrator’s instructional prompts and associations with learning outcomes. Results indicated that children were highly successful in responding with the narrator’s task-management prompts (i.e., turn the page), particularly after the first book. Children were much less proficient in correctly responding to the narrator’s word-teaching prompts …

The Effects Of Sensorineural Hearing Impairment On Asynchronous Glimpsing Of Speech, Erol J. Ozmeral, Emily Buss, Joseph W. Hall Iii

Communication Sciences and Disorders Faculty Publications

In a previous study with normal-hearing listeners, we evaluated consonant identification masked by two or more spectrally contiguous bands of noise, with asynchronous square-wave modulation applied to neighboring bands. Speech recognition thresholds were 5.1–8.5 dB better when neighboring bands were presented to different ears (dichotic) than when all bands were presented to one ear (monaural), depending on the spectral width of the frequency bands. This dichotic advantage was interpreted as reflecting masking release from peripheral spread of masking from neighboring frequency bands. The present study evaluated this effect in listeners with sensorineural hearing loss, a population more susceptible to spread …
