The Contribution Of Mild Traumatic Brain Injury/Concussion To The Development Of Post-Traumatic Stress Disorder Symptoms, Kylie Lauren Marshall

Open Access Theses & Dissertations

A controversial issue is whether TBI is a necessary precursor to the development of PTSD symptoms, or if the two variables are mutually exclusive. Recent rodent-models reveal that a stressful environment cannot cause PTSD symptoms directly without TBI, yet it is unknown if PTSD symptoms can develop following a TBI. This study provides a potential analogue to study this relationship by evaluating the effects of sports-related concussion. Purpose: This study investigated two questions, 1) Is there a significant difference in the frequency of PTSD symptoms reported by athletes at baseline (BL) testing and post-concussion (PC) testing over time? 2) Is …

Purpose: The purpose of this study is to measure the effects of baby sign training on the overall development of normally hearing children while improving on the limitations of current studies (between group study). Methods: Participants in the study included 22 children, ages 6 months to 2 years; …

A Comparative Assessment Of Electrophysiological And Behavioral Performance In Individuals With Aphasia Responding To Spoken And Written Sentence Length Commands, Sha-Renae Alexander

Open Access Theses & Dissertations

The aim of this study is to investigate whether deficits in processing affect auditory and reading comprehension in the same manner. This study compared the behavioral and electrophysiologic performance of four individuals with aphasia and four participants with no brain damage responding to spoken and written sentence length commands using a modified version of the Revised Token Test (McNeil & Prescott, 1978). Electrophysiological responses were recorded from the scalp using event related potentials (ERP). The latency and amplitude of the N400 ERP component were measured and analyzed. Behavioral reaction times and correct responses were collected and examined. Performance differences between …

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 …

The Impact Of Accented English On Speech Comprehension, Benigno Valles

Open Access Theses & Dissertations

ABSTRACT

In the context of shifting demographics in the United States and with an increasing multicultural workforce, the verbal exchange of information is vital especially between health care providers and patients. Although English is the official language in the United States, many individuals from different national origins speak English with some degree of accent. Before we can address health care provider/patient communication, it is necessary to investigate the potential impact of accented English on speech comprehension and its implications on basic communicative interactions. The verbal exchange of information between health care providers and patients is important in diagnostics, treatment, patient …

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 …

Acoustic Realization Of Contrastive Stress In Individuals With Parkinson's Disease, Ana Maria Gaviria

LSU Master's Theses

This study investigated the acoustic correlates of contrastive stress produced by individuals with Parkinson’s disease (PD) to learn more about their ability to modulate acoustic cues to mark contrastive stress. Speech materials from 10 individuals with PD and 10 gender- and age-matched neurologically healthy controls (HC) were recorded and analyzed. The four acoustic measures (peak intensity, peak F0, vowel duration, and acoustic vowel space area) of stressed and unstressed syllables were compared to determine which acoustic parameters are preferentially employed by each group to mark contrastive stress. The results indicated that individuals with PD exhibited significant changes in vowel duration …

Reliability Of Subjective Endoscopic Parameters In The Differentiation Of Essential Voice Tremor And Adductor Spasmodic Dysphonia Using High-Speed Videoendoscopy, Lindsey A. Parker

LSU Master's Theses

Certain neurogenic voice disorders present with similar or overlapping audio perceptual voice characteristics. Developing reliable and standardized perceptual measures of vocal fold vibratory characteristics for such voice disorders can enable accurate diagnosis and lead to faster, targeted treatment. In this study, subjective perceptual vocal fold vibratory characteristics and the presence and absence of supraglottic events during phonation were investigated to differentiate between Adductor Spasmodic Dysphonia (ADSD) and Essential Vocal Fold Tremor (EVT) using high-speed videoendoscopy (HSV). The specific aims of the study were to 1) assess which subjective endoscopic vocal fold vibratory measures differentiate EVT from AdSD; and 2) assess …

Do People With Aphasia Interpret Road Signs Differently Than People Without Aphasia?, Caitlin Elise Brown

LSU Master's Theses

Purpose: This study increased our understanding of how aphasia may affect interpretation of road signs. Background: Despite aphasia’s theoretical effects on road sign comprehension and promising initial findings in studies that investigated driving and aphasia, the literature examining aphasia and road signs has been sparse. Research has shown that aphasia may have some effect on road sign interpretation. However, more study is needed regarding both accuracy and response time to road sign interpretation, which are equally important for safe driving. Methods: This was a prospective, between group study that used data collected from a larger study by Donovan, Savage, Varnado, …

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

LSU Doctoral Dissertations

The purpose of this study was to identify how SLP communication regarding language disorders was perceived by caregivers. 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 …

Evaluation Of Teacher Ratings To Improve Child Language Screenings In Speech-Language Pathology, Kyomi Dana Gregory

LSU Doctoral Dissertations

The purpose of this study was to examine the validity of teacher ratings for screening children’s language skills. Teacher ratings were measured through the use of two tools, the Children’s Communication Checklist-2 (CCC-2; Bishop, 2006) and the Teacher Rating of Oral Language and Literacy (TROLL; Dickinson, McCabe, & Sprague, 2001). The data for this study were from 77 kindergarteners who lived in rural Louisiana and spoke a non-mainstream dialect of English; 51 were classified as typically developing and 26 as presenting with Specific Language Impairment. Convergent validity was examined by comparing the two teacher rating tools to each other and …
