Semantic Knowledge Use In Discourse Produced By Individuals With Anomic Aphasia, Stephen Kintz, Heather Harris Wright, Gerasimos Fergadiotis

Gerasimos Fergadiotis

Background---Researchers have demonstrated that people with aphasia (PWA) have preserved semantic knowledge (Dell et al., 1997; Jefferies & Lambon Ralph, 2006). However, Antonucci (2014) demonstrated that some PWA have impaired access to certain types of knowledge more than others. Yet, all these studies used single concepts. It has not been demonstrated whether PWA have difficulty accessing certain types of features within a discourse sample.

Aims—The main goals of this study were to determine if semantic knowledge and two category types were used differently within discourse produced by participants with anomic aphasia and healthy controls.

Method & Procedures—Participants with anomic ...

Outcomes Of Speech And Language Pilot Program For International Students, Kelly Fussman

Honors College Capstone Experience/Thesis Projects

Universities in the United States host a substantial number of international students every academic year. As of the 2015-2016 academic year, Western Kentucky University, located in south-central Kentucky, alone hosts over 1,400 international students. These students often face a number of challenges upon arrival in the United States, especially when it comes to language and cultural differences. A considerable body of research indicates that international students’ educational performance and outcomes are significantly impacted by their cultural identities, psychological and sociocultural experiences, and attitudes in relation to English-speaking societies. Many international students attribute academic and social difficulties to a lack ...

Analyzing Spelling Errors By Linguistic Features Among Children With Learning Disabilities, Christine Johnson

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 error severity and frequency ...

Effects Of A Novel Right Brain Intervention On Stuttering In Familiar And Structured Speech Tasks, Josalyn Elizabeth Perry

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 ...

Interspeech Posture In Spanish-English Bilingual Adults, Merrily Rose Shary

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 the typical ISP for each language must be determined. Therefore, the purpose of this study was to extend the research by Wilson and Gick (2014) to investigate ISP in Spanish-English speaking adults.

To this end, 13 bilingual Spanish-English adults were asked to produce 30 sentences while speaking in monolingual and bilingual modes. While they were speaking, ultrasound images of the oral cavity were obtained by placing a probe sub-mentally and analyzing the position of the tongue using Articulate Assistant Advanced 2.0 software (Articulate Instruments, 2012). Tongue and palate contour measurements were made by using a curved tongue spline that was manually drawn and semi-automatically fit to each speaker’s tongue/palate contour. ISP was measured using the participant’s tongue tip height along a reference angle from the probe to the alveolar ridge. Additionally, monolingual English speaking adults were asked to rate the accentedness of each bilingual’s speech in English as a behavioral correlate of language proficiency.

Overall results of this study were non-significant; bilingual Spanish-English speakers utilized similar postures in monolingual Spanish and English modes, and in bilingual mode, in contrast with the findings of Wilson and Gick (2014). Accentedness ratings in English v indicated that the bilingual speakers were relatively uniform in their lack of accentedness. Although overall results from ...

Effects Of A Novel Right Brain Intervention On Stuttering Frequency In Unfamiliar Speech Tasks, Chelsea Beatrice Stewart

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

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 number of spelling ...

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

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 ...

Prediction In Aging Language Processing, Spyridoula Cheimariou

Theses and Dissertations

This thesis explores how predictions about upcoming linguistic stimuli are generated during real-time language comprehension in younger and older adults. Previous research has shown humans' ability to use rich contextual information to compute linguistic prediction during real-time language comprehension. Research in the modulating factors of prediction has shown, first, that predictions are informed by our experience with language and second, that these predictions are modulated by cognitive factors such as working memory and processing speed. However, little is known about how these factors interact in aging in which verbal intelligence remains stable or even increases, whereas processing speed, working memory ...

Age-Related Changes In Temporal Resolution Revisited: Findings From Cochlear Implant Users, Bruna Silveira Sobiesiak Mussoi

Theses and Dissertations

A decline in temporal resolution, or the ability of the auditory system to track fast changes in incoming sounds, is one factor thought to contribute to difficulties in speech perception that accompany the aging process. Aging effects on gap detection abilities, using behavioral or isolated electrophysiologic measures, have been studied previously. However, peripheral and central electrophysiological, and behavioral measures of temporal resolution have not been examined in the same subjects. Also, the relationship between age-related changes in temporal resolution and speech perception is still unclear, as is their interaction with cognition. By revisiting this question in CI users, it was ...

The Effect Music Has In Speech Therapy, Emily K. Nester

Honors Theses

The purpose of this exploratory study was to determine the use of music in speech therapy. A survey was sent via email to Mississippi Speech-Language-Hearing Association (MSHA) certified speech-language pathologists to acquire knowledge on the use of music in their therapy sessions. The author used the source, SurveyMonkey, to collect and analyze the data. The data was used to determine the prevalence of music in speech therapy. In addition, when music was used, the data portrayed how music was incorporated into therapy and the particular gender, genre, and/or disorder preferred.

A Case Study Of Cochlear Implants And Complications, Carly E. Amurao

Senior Honors Projects

A cochlear implant is an electronic medical device that replaces the function of the damaged inner ear, allowing the individual access to sound. In recent years, there has been tremendous progress in developing technology in the area of cochlear implants to aid those with severe/profound hearing loss. Specifically, there has been a movement towards bilateral implantation. Each cochlear implant candidate has a unique hearing loss, and must reach required bench marks in order to be considered a viable candidate for a cochlear implant. This process includes: meeting the required level of hearing loss, a required trial with hearing aids ...

Creating Therapy Materials To Improve Communication Of Young Children, Allison J. Corey

Senior Honors Projects

Once children start preschool, they should be able to speak in simple sentences and use basic syntax. When they complete preschool and begin kindergarten, they should be using complete, complex sentences, have an extensive vocabulary, and use correct grammar. However, sometimes a child’s language doesn’t develop as expected resulting in speech delays or impairments. This problem could arise for a multitude of reasons, for example, the child may be on the autism spectrum, he/she may have a specific language delay, or it may be due to an articulation/phonology problem. The role of a speech language pathologist ...

Verification And Quantification Of Surface Electromyographic (Emg) Activity Of The Masseter Muscle, Kelsey Bowles

Honors Theses

Purpose: The goal of the present study is to develop and evaluate an automated technique for measuring biting and chewing related surface electromyographic (EMG) activity of the masseter muscle.

Methods: Data from 28 neurologically healthy participants between the ages of 18-40 were selected for this study. The procedure for collecting the bite/chew data consisted of the participant biting down and chewing three small breath mints while an EMG sensor recorded the masseter muscle activity. A five-step Matlab-based algorithm was created to accurately identify onsets and offsets of each bite and chew event.

Results: Compared to manual measurements using ...

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 ...

The Effect Of Signal-Independent Information And Sentence Predictability On Speech Comprehension In Babble Noise For Typical Hearing Young Adults, Mariah N. Smart

Linguistics Senior Research Projects

The influence of signal-independent information and sentence predictability on listeners’ comprehension was investigated by measuring transcription accuracy of a series of English sentences spoken in multi-talker babble background noise with circumstances varying between sets of sentences. Fourteen native English speaking young adults with no self-reported hearing or language disabilities completed written transcriptions of four sets of sentences. Listeners were presented with a control set of the signal alone, followed by a set of sentences spoken in multi-talker babble noise, then a set with visual presence of the speaker included, and finally a set where content context was given in addition ...
