Processing Of Language Switches In Bilingual Individuals With Aphasia: An Event-Related Potential Comparison, Lizette Rodarte

Open Access Theses & Dissertations

Switching between languages, or code-switching, is a common phenomenon in bilingual individuals. In proficient bilinguals, these switches are done with ease and are used for many purposes. Contrary to popular belief, these switches are rule-governed and follow grammatical structure. Bilingual individuals diagnosed with aphasia present with difficulty processing languages and these language switches. With the increase in bilingual individuals, it is likely that the speech-language pathology community will see an increase of bilingual individuals with aphasia on their caseload. For this reason, the purpose of this study is to increase our understanding of the neural processes involved in processing of …

Event Related Potentials In A Two Stimuli Auditory Oddball Task In Concussed College Athletes: A Linguistic Component Replication Study, Christopher Anthony Roosmalen

Open Access Theses & Dissertations

Concussions affect an estimated 1.6 to 3.8 million individuals annually and can result in persistent symptoms and cognitive impairments in attention and memory. Concussions are a rising health concern especially in concussion management. Event Related Potentials (ERP) may more accurately assess cognitive recovery making better return to play decisions. In 2013, Sanchez found no significant difference between concussed athletes and non-concussed individuals in the in amplitude of the P300 ERP component using an auditory oddball task consisting of 2 different consonant, vowel (CV) syllables. Because participants were instructed to maintain a mental and verbal count of the target stimuli, a …

High Definition Transcranial Direct Current Stimulation Als Mogelijke Hulp Bij Afasie-Herstel, Dirk B. Den Ouden

Communication Sciences and Disorders Faculty Articles and Research

Samenvatting

Nieuwe kennis over het plastische vermogen van het volwassen brein, ook na hersenschade, heeft geleid tot hernieuwde interesse in technieken om deze plasticiteit fysiek te sturen. Een van die technieken is transcranial Direct Current Stimulation (tDCS), waarmee de exciteerbaarheid van hersencellen beïnvloed wordt door een zwakke gelijkstroom door de hersenschors te leiden. Als met deze methode hersenplasticiteit bevorderd en gestuurd kan worden, is het wellicht mogelijk om de uitkomsten van afasietherapie te verbeteren, door het aanpakken van de fysieke bron van de stoornis. Dit artikel behandelt kort de geschiedenis en de werking van tDCS, alvorens een overzicht te geven …

Comparison Of Acoustic Measures In Discriminating Between Those With Friedreich's Ataxia And Neurologically Normal Peers, Sophia Luna-Webb

HIM 1990-2015

Background: Technological advancements in speech acoustic analysis have led to the development of spectral/cepstral analyses due to questions regarding the validity of traditional time-based measures (i.e., Jitter, Shimmer, and Harmonics-to-Noise-Ratio) in objectifying perturbations in dysphonic voices. Aim: This study investigated the validity of time-based measures in discriminating those with Friedreich’s ataxia (FA) from normal voiced (NV) peers when compared to cepstral-spectral measures. Method: A total of 120 sustained vowel phonations from an existing database of 40 participants (20 FA; 20 NV) of the vowels /ɑ/, /i/, and /o/ were analyzed to determine which set of variables (i.e., time-based vs. cepstral-spectral) …

Standardized Articulation Test Performance Of African American Preschoolers In Mississippi, Emily Ortega

Honors Theses

In the past, standardized articulation tests administered by speech-language pathologists (SLPs) have had tendencies to be biased against speakers of a dialect with characteristics that differ from Mainstream American English (MAE). Using these MAE norm referenced tests can cause several problems, including over diagnosing African American (AA) children with impaired speech and language. The purpose of this study is to document the performance of four-year-old African American English (AAE) speakers for their use of age appropriate phonemes regardless of dialect, and whether the presence of AAE affects participants' scores on the following articulation tests: the Arizona Articulation Proficiency Scale-Third Edition …

Parent/Caregiver Knowledge And Satisfaction Of Information And Referrals Related To Speech-Language Pathology Services For Children With Down Syndrome, Erin K. Salmons

Theses and Dissertations--Communication Sciences and Disorders

Down syndrome, also known as Trisomy 21, is the most commonly occurring chromosomal abnormality present at birth. The Centers for Disease Control and Prevention estimates that there are approximately 6,000 diagnoses of Down syndrome per year in the United States, further indicating that 1/700 infants are born with Down syndrome. A diagnosis of Down syndrome can be made either prenatally or postnatally. Early intervention services will be warranted to address underlying deficits associated with the syndrome, (i.e., speech-language/feeding/swallowing). Communicative disorders are among the most prominent concomitant deficits associated with Down syndrome. Therefore, it is critical that parents/caregivers of children with …

Dialect And Word Learning: Are Phonological Properties Maintained When Dialectal Influence Changes Word Meaning?, Heather C. Iwinski

Theses and Dissertations--Communication Sciences and Disorders

Word learning requires the accurate encoding and decoding of a word’s phonological and semantic properties. Errors in establishing an accurate phonemic-semantic connection can hinder accurate word comprehension and use. Geographical location, culture, and ethnicity can affect the phonology used by a speaker referred to as dialect. African American Vernacular English (AAVE) is one of the most commonly used dialects in the United States. In addition to grammatical changes AAVE is characterized by phonemic changes. The current study sought to determine the effects of AAVE use on the receptive and expressive learning of nonsense words that differ in meaning as noted …

All were developing language typically, and the groups were matched on a number of socio-demographic variables and …

An Analysis Of Spelling Patterns Produced By Elementary School-Aged Speakers Of African American English, Lindsay Meyer Turner

LSU Doctoral Dissertations

Over the years, less attention is given to students’ spelling skills compared to other areas of literacy achievement like word reading and passage comprehension in relationship to nonmainstream dialect usage. Considering that English spelling is based on the phonological and morphological structures of Mainstream American English (MAE), it is likely that children who speak a nonmainstream dialect such as African American English (AAE) will demonstrate differences in their spelling abilities. The purposes of this study were to explore the relationship between degree of AAE dialect use and spelling for a group of first to third grade children, and to describe …

Effects Of Encoding Practice On Alphabet, Phonemic Awareness, And Spelling Skills Of Students With Developmental Delays, Laura Nicole Delrose

LSU Doctoral Dissertations

Reading instruction has historically been deemphasized for students in special education, and the limited research on this topic reveals that sight word vocabulary is most commonly taught in special education classrooms (Browder, Wakeman, Spooner, Ahlgrim-Delzell, Algozzine, 2006). However, successful reading instruction must target the five essential components: vocabulary, fluency, comprehension, phonics, and phonemic awareness (National Reading Panel, 2000). The extremely small body of research attempting to teach phonics and phonemic awareness to students with mild to severe disabilities approaches instruction from a decoding framework with mixed success (Browder et al., 2006). Alternatively, this study aims to teach from an encoding …

Caregiver Perceptions Of Speech-Language Pathologist (Slp) Communication: Examining How Slps Talk With Caregivers About Child Language Disorders, Karmen L. Porter

LSU Doctoral Dissertations

Employing a qualitative methodology, the caregivers of 10 children, identified with a language-based reading impairment, participated in semi-structured interviews concerning their experiences communicating with SLPs. As a whole, the findings showed the value caregivers place on receiving clear, concrete, and timely diagnostic information, the variability and complexity associated with caregivers’ understanding of language disorders, and the reciprocal relationship between key SLP communication practices, caregiver knowledge, and effective collaboration. Some of the key themes emphasized in regard to SLP communication practices included: recognition …

Va-Et-Vient, The Goin' And Comin' Of Infinitival 'To': A Study Of Children With And Without Specific Language Impairment In Cajun English, Andrew Mandell Riviere

LSU Doctoral Dissertations

The purpose of this study was to examine Cajun English (CE)-speaking children’s marking of infinitival TO. To do this, CE-speaking children’s marking of infinitival TO was compared to the marking of infinitival TO by Southern White English (SWE)- and African American English (AAE)-speaking children. Marking of infinitival TO also was examined as a function of the children’s clinical status (i.e., Specific Language Impairment, SLI, or typically developing, TD) and by the verb contexts that preceded the infinitival TO forms.

The data came from 180 kindergarteners who lived in four rural towns in Assumption Parish, Louisiana. The children’s dialect classifications were …
