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 …

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 …

Social Support, Social Companionship, And Social Distress In Young Adults With Cochlear Implants, Arta Ljubanovic

Dissertations, Theses, and Capstone Projects

Research has shown that social support has a positive impact on mental health and decreases levels of stress in young adults with normal-hearing sensitivity. Social relationships are one psychological construct that has not been previously studied in young adults with cochlear implants. In light of the importance of social support in the overall well-being of an individual and the lack of research on this topic in individuals with cochlear implants, the study purpose is to examine social relationships in young adults with cochlear implants and to determine the presence of any significant differences in social relationships between the group with …

Development Of A Patient-Centered Health Literacy Toolkit For Audiology And Hearing Loss (The 'Hh Lit Kit'), Jennifer L. Gilligan

Dissertations, Theses, and Capstone Projects

The Patient-Centered Health Literacy Toolkit for Audiology & Hearing Loss (‘HH Lit Kit’) represents four years of inquiry into health literacy and Patient-Centered Care (PCC) in audiology. While awareness of health literacy continues to gain momentum in medicine and public health, there is a paucity of information on PCC and health literacy in audiology.

Low health literacy is linked to poorer health and poorer quality of life. Patients with hearing loss are at high risk for low health literacy. This presents a major concern because hearing loss affects the way information is processed, retained, and applied. Gaps have been identified …

Social Isolation, Social And Emotional Loneliness, And Self-Reported Hearing Difficulties In Older Adults With Hearing Loss, Yuliya Borik

Dissertations, Theses, and Capstone Projects

Hearing loss is known to affect communicative ability and has been associated with poor health-related outcomes such as impaired cognition, increased risk for falls, and psychotic manifestations. Social isolation and loneliness are also widely recognized to negatively impact mental and physical health. The purpose of this systematic review is to review literature that explores a relationship between hearing loss with and/or without self-reported hearing difficulties and social isolation and social and emotional loneliness in older adults with hearing loss ranging from mild to profound. The goal is to determine whether there is a direct relationship between subjective and/or objective hearing …

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 …

Hearing Aid Use And Cognitive Function: A Systematic Review, Hershel Korngut

Dissertations, Theses, and Capstone Projects

This systematic review analyzed the research relating the use of hearing aids to cognitive function. Hearing aid use was examined to see if wearing hearing aids improves cognitive function, if the length of time hearing aids are worn impacts cognitive ability, if the type of hearing aid used has any impact on cognitive function, and if hearing aid use slows down cognitive decline. Ten studies met the criteria for this review. An analysis of the research revealed some evidence to support wearing hearing aids improves cognitive function, however, there is substantial evidence that shows no impact between wearing hearing aids …

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 A Social Communication Intervention On The Production Of Emotion Words For Children With Language Impairment, Emilee Anne Longmore

Theses and Dissertations

Many school-age children with a diagnosis of Language Impairment (LI) also have social communication difficulties. Some of these difficulties are related to deficits in emotion understanding. This thesis evaluates the effects of a social communication intervention designed to increase the production of emotion-based words as an indicator of emotional competence. For five elementary school-aged children with LI, the production of emotion-based words was analyzed by first determining the frequency of words produced in preintervention sessions for the following categories: happiness, sadness, anger, fear, surprise, and disgust. Following these measures, the participants received 20 intervention sessions over the course of treatment. …

Bidirectional Interference Between Simulated Driving And Speaking, Kelsey Lynn Simmons

Theses and Dissertations

The purpose of this study was to examine interference between concurrently performed speaking and driving tasks. Participants included 60 adults, 30 males and 30 females, with no history of communication disorders. They were divided into three different age groups of 20 participants each: younger (20s), middle-aged (40s), and older (60s). The participants were given a list of topics to consider and were instructed to select eight topics that they could talk about; they completed five practice trials of the driving simulator prior to the experimental recording to eliminate practice effects. Each participant completed the speaking task and driving task both …

Annexin A5 Is The Most Abundant Membrane-Associated Protein In Stereocilia But Is Dispensable For Hair-Bundle Development And Function, Jocelyn F. Krey, Meghan Drummond, Sarah Foster, Edward Porsov, Sarath Vijayakumar, Dongseok Choi, Karen Friderici, Sherri M. Jones, Alfred L. Nuttall, Peter G. Barr-Gillespie

Department of Special Education and Communication Disorders: Faculty Publications

The phospholipid- and Ca²⁺-binding protein annexin A5 (ANXA5) is the most abundant membrane-associated protein of ~P23 mouse vestibular hair bundles, the inner ear’s sensory organelle. Using quantitative mass spectrometry, we estimated that ANXA5 accounts for ~15,000 copies per stereocilium, or ~2% of the total protein there. Although seven other annexin genes are expressed in mouse utricles, mass spectrometry showed that none were present at levels near ANXA5 in bundles and none were upregulated in stereocilia of Anxa5^−/− mice. Annexins have been proposed to mediate Ca²⁺-dependent repair of membrane lesions, which could be part of the …

Psychometrically Equivalent Bisyllabic Word Lists For Spanish Pediatric Word Recognition Testing, Brenda Karina Peterson

Theses and Dissertations

While recorded speech audiometry materials have been developed in Spanish for adults, currently there are no speech audiometry materials available in Spanish that are suitable for a pediatric population. Thus, the purposes of this study were (a) to analyze Spanish bisyllabic words previously developed for adults to determine the words' appropriateness when testing word recognition scores in native Spanish-speaking children and (b) to compare the logistic regressions results from the Spanish adult data obtained in a previous study with the logistic regressions from Spanish pediatric data obtained in the present study. Using common-use children's dictionaries in the Spanish language, a …

The Efficacy Of A Literature-Based Social Communication Intervention On Teacher Report Of Sociability For Children With Language Impairment, Mnisa Lyn Harlow

Theses and Dissertations

Recent research indicates that children with language impairment (LI) often experience difficulties with social communication. Although the empirical basis for general social communication intervention is growing, information documenting the efficacy of these interventions for children with LI remains limited. The purpose of this study was to examine the effectiveness of a social communication intervention on teacher perceptions of sociability in five elementary-aged children with LI. The intervention focused on the presentation and use of children's stories to target aspects of emotion understanding. The two sociability subscales of the Teacher Behavior Rating Scale (TBRS), impulse control/likeability and prosocial behavior, were used …

Mean Length Of Utterance And Developmental Sentence Scoring In The Analysis Of Children's Language Samples, Laurie Lynne Chamberlain

Theses and Dissertations

Developmental Sentence Scoring (DSS) is a standardized language sample analysis procedure that uses complete sentences to evaluate and score a child’s use of standard American-English grammatical rules. Automated DSS software can potentially increase efficiency and decrease the time needed for DSS analysis. This study examines the accuracy of one automated DSS software program, DSSA Version 2.0, compared to manual DSS scoring on previously collected language samples from 30 children between the ages of 2;5 and 7;11 (years;months). The overall accuracy of DSSA 2.0 was 86%. Additionally, the present study sought to determine the relationship between DSS, DSSA Version 2.0, the …

The Association Between Articulator Movement And Formant Trajectories In Diphthongs, Katherine Morris Mckell

Theses and Dissertations

The current study examined the association between formant trajectories and tongue and lip movements in the American English diphthongs /aɪ/, /aʊ/, and /ɔɪ/. Seventeen native speakers of American English had electromagnetic sensors placed on their tongues and lips to record movement data along with corresponding acoustic data during productions of the diphthongs in isolation. F1 and F2 trajectories were extracted from the middle 50% of the diphthongs and compared with time-aligned kinematic data from tongue and lip movements. The movement and formant tracks were converted to z-scores and plotted together on a common time scale. Absolute difference scores between kinematic …

Cultural Competence And Ethical Decision Making For Health Care Professionals, Brenda Louw

ETSU Faculty Works

Cultural competence and ethical decision making are two separate, yet intrinsically related concepts which are central to services rendered by all health care professionals. Cultural competence is based on ethical principles and informs ethical decision making. In spite of this important connection, the interrelationship of these two concepts does not receive the attention it deserves in the literature. This issue is addressed by appraising the training and assessment of cultural competence and ethical decision making in the health care professions. The integrated relationship of these two concepts is illustrated within the broader contexts of higher education, research and clinical practice. …
