Children enrolled in kindergarten through third grade completed tasks that target language and literacy skills, and their parent(s) completed …

The Effect Of Visual Feedback On Vocal Compensation Abilities In Individuals With Post-Stroke Aphasia, Marissa Rylee Olson

Theses and Dissertations

Speech production is a complex and highly organized process comprised of various sensory and perceptual components. Post-stroke aphasia can impair speech production abilities by interrupting individuals’ ability to detect and correct speech errors and produce their targeted behavior. Contemporary models of speech production aim to understand the relationship between sensory systems and the human ability to produce perceptually accurate speech. This study seeks to understand the relationship between visual feedback and vocal compensation abilities in individuals with post-stroke aphasia to determine the effectiveness of incorporating visual feedback into therapeutic expressive language intervention. It was hypothesized that that the multi-sensory experimental …

Orthographic Knowledge And Phonological Awareness In Children With Speech Sound Disorder, Anna Marie Ehrhorn

Theses and Dissertations

Speech sound disorder (SSD) puts children at risk for word reading difficulties but does not guarantee them. Research on early literacy skills in children with SSD has primarily focused on phonological awareness due to speech sound deficits associated with SSD. Researchers have begun to examine multiple factors beyond phonological awareness that may impact word reading and spelling development. Orthographic knowledge is another essential factor understudied in children with SSD. Previous research has shown that orthographic properties of words influence phonological awareness performance in skilled readers and children with reading difficulties. No known previous studies have examined whether orthography influences phonological …

Behavioral And Neurophysiological Measures Of Speech Auditory Feedback Processing Impairment In Left Hemisphere Stroke, Stacey Sangtian

Theses and Dissertations

The purpose of this study was to identify behavioral and neural correlates of impaired speech auditory feedback processing in people with a history of left-hemisphere stroke (LHS). To do this, we used the altered auditory feedback (AAF) paradigm to externally induce speech errors by randomly shifting the pitch frequency of the online auditory feedback up or down at ±100 cents in 38 LHS and 27 neurologically intact control participants under two experimental conditions: 1) active vocalizations of a steady speech vowel sound “ah,” and 2) passive listening to the playback of the same self-produced vocalizations. Randomized control trials were included …

Transcranial Alternating Current Stimulation As An Adjuvant For Nonfluent Aphasia Therapy: A Proof-Of-Concept Study, Lynsey Mcgrath Keator

Theses and Dissertations

Identifying effective and efficient rehabilitation tools is crucial to improve language outcomes for persons living with chronic aphasia. Speech entrainment has proved to be particularly successful in improving speech output in nonfluent aphasia. It is hypothesized that, for patients with aberrant oscillatory synchronization between anterior and posterior language regions of the left hemisphere, speech entrainment may act as an external gaiting mechanism to bolster an impaired efference copy and improve synchrony between these regions. Theoretical and empirical evidence supports this idea that speech production relies on anterior-posterior connectivity in the left hemisphere.

Transcranial alternating current stimulation (tACS) delivers low, periodically-alternating …

Feasibility And Preliminary Outcomes Of A 6-Week Mindful Walking Program To Maintain And Improve Cognition In Adults At Risk For Alzheimer’S Disease Or Other Related Dementias, Caroline Mannion Wood

Theses and Dissertations

The present study examined the impact of a 6-week Mindful Walking intervention. Participants completed 30 minute walking sessions twice a week for 6 weeks. Ten older adults attended 100% of the supervised walking sessions. Pre-post comparison of the Montreal Cognitive Assessment and examination of subtests of the Montreal Cognitive Assessment did not reveal a significant change in mean scores (p.05, one-tailed). The number of steps accumulated as a result of Mindful Walking and other activities measured with the ActivPAL and change in MoCA total scores did not reach significance. Generally, the Mindful Walking program was well-liked (4 on a scale …

Measuring Orthographic Influences On Phonological Processing In Beginning Readers: An Eyetracking Study, Emily Grace Fisher

Theses and Dissertations

Purpose – Both orthographic and phonemic awareness are essential to reading. However, the role of orthographic knowledge in phonemic awareness has not been thoroughly investigated in beginning readers until recently. The purpose of this study was to examine if orthographic knowledge influenced phonological processing in beginning readers and to establish a proof of concept for the use of eyetracking measures to examine these skills in young children.

Method – 22 participants, aged 6-7 years, completed norm-referenced assessments of language and reading ability as well as experimental measures of orthographic and phonological awareness while their eye movements were monitored.

Investigating The Impact Of Nonlinguistic Cognitive Reserve On Naming Pre- And Post-Treatment, Lillian Jarold

Theses and Dissertations

Background: The relationship between linguistic and nonlinguistic cognition in persons with aphasia is complex and often debated in the literature. Furthermore, the impact of nonlinguistic cognition on aphasia treatment outcomes is unclear. The present study sought 1) to examine the relationship between WAIS scores and performance on a test of naming and 2) to examine the relationship between WAIS scores and change scores on a test of naming between baseline and post-treatment in persons with chronic aphasia.

Method: This retrospective study utilized data from participants (N=102) who were recruited for a multi-center cross-over trial (POLAR: Predicting Outcomes of Language Rehabilitation). …

A Comparative Study On The Expository Writing Abilities Of Kindergarten Students With And Without Developmental Language Disorder, Kristine Michelle Dayley Andrus

Theses and Dissertations

State standards require kindergarten students to produce expository writing, but little research has been done regarding their abilities in this area. This study describes expository writing samples of 47 typically developing (TD) kindergarteners and 43 kindergarteners with developmental language disorder (DLD). The Expository Language Measures (ELM) Flow Chart and the Systematic Analysis of Language Transcripts (SALT) software were used to detail the language complexity and text structure features the children in the sample produced. When comparing TD and DLD children's expository written samples, no significant differences in the language and text structure measures were found. It is important to continue …

Intolerance Of Uncertainty, Sensory Processing, And Related Correlates In Autistic Children During The Covid-19 Pandemic, Mollie Bradley

Theses and Dissertations

The COVID-19 pandemic increased uncertainty and anxiety for most and was especially disruptive to autistic people and their families. Autistic children were particularly vulnerable due to their intolerance for increased uncertainty and disruption to their school and therapy support. This study aimed to investigate the effect that increased uncertainty had on autistic children, specifically their sensory behaviors and stress levels and on the stress levels of their primary caregivers. Parents and guardians of 47 autistic children completed an online survey consisting of questions investigating background and demographic information, their experiences during the first six months of the pandemic, information about …

The Analysis Of Omission And Substitution Errors In Various Language Tasks In Bilingual Children, Macy Whiting

Theses and Dissertations

As the population of Spanish-English bilingual children in the United States steadily grows, the importance of accurately assessing and diagnosing developmental language disorder (DLD) has also grown. Understanding a child's underlying language learning system is critical in this process. Several studies have demonstrated the efficacy of nonword repetition (NWR) tasks in bilingual children across a wide range of development, however there is little information regarding guidelines for interpretation of NWR performance or analyzing error patterns. This study was conducted to address these gaps in the research. A sample of 26 Spanish-English bilingual school aged children (6;0-9;4) were administered English and …

The Impact Of Background Noise On The Communicative Experience Of People With Mild To Moderate Aphasia: A Qualitative Study, Riley Robertson Hegewald

Theses and Dissertations

This study examined how retelling stories with a variety different background noise conditions affected the communicative experiences of people with aphasia (PWA). Participants included 11 adults with mild to moderate aphasia and 11 age- and gender-matched controls. Participants participated in a semi-structured interview immediately following the experimental measure where they were asked open-ended questions regarding their experience retelling stories and how those experiences related to their everyday lives. Results revealed three themes related to how participants responded to communicating in noise: (a) cognitive reactions, (b) emotional reactions, and (c) social reactions. The findings suggest that PWA exert more effort when …

A total of 19 participants were recruited and divided into control and experimental groups. Of these 19, 10 were assigned to the experimental group (E) which required participants to engage in increasing their fluid intake by 1 liter per day, while the remaining 9 were part of the control group (C) and had no additional instructions.

To gather perceptual data, a survey was created and conducted via Qualtrics software, and addressed …

An Analysis Of Mental State Verbs In Children With Hearing Loss, Morgan Vachio

Theses and Dissertations

Mental state verbs (MSV) require unique cognitive and linguistic knowledge compared to lower level function words (Shatz et al., 1983). These cognitive and linguistic demands are thought to be difficult for children with hearing loss (CHL) due to deficits in word learning (Werfel, 2017; Lund, 2016), limited depth of vocabulary knowledge (Walker et al., 2018) and deficits in complex syntax (Werfel et al., 2021). The present study recruited 73 preschool children (23 CHLCI, 22 CHL-HA and 28 CNH) to participate. Our analysis examined the frequency, lexical diversity and use of MSV within required complex syntax structures.

Verbal Fluency In Women With The Fmr1 Premutation And The Broad Autism Phenotype, Emily Szabo

Theses and Dissertations

Women who carry a premutation allele on the FMR1 gene can experience limitations due to their genetic status, including executive function deficits. These subtle deficits are often shared by women who possess the broad autism phenotype (BAP). Poor understanding and limited research on the extent of these executive functioning deficits has led to limited clinical management of these two groups. The current study aimed to clarity whether there is a difference in verbal fluency abilities in mothers that possess the FMR1 premutation, mothers of children with autism who are at risk for the BAP, and mothers of typically developing children, …

Lexical Properties Of Perceptual Errors Made By Younger And Older Adults Listening To Speech In Multitalker Babble, Hannah Blythe Vickery

Theses and Dissertations

Purpose: The purpose of this error analysis was to analyze the lexical properties of misperceptions made when listening to speech in multitalker babble.

Methods: Twenty young adults with normal hearing (YNH), 20 older adults with normal hearing (ONH), and 22 older adults with hearing impairment (OHI) completed a speech-in-babble task. Participants were asked to repeat the final word in 25 high and 25 low context sentences. On each trial, participants either responded with the correct target word, a misperception error, or skipped the trial response. Misperceptions were compiled and analyzed according to their lexical properties.

Towards Understanding Therapy Response In Chronic Aphasia, Sigfus Kristinsson

Theses and Dissertations

It remains largely unclear what factors determine who responds to aphasia therapy and to what degree. The current study sought to ameliorate this issue by addressing three aims: 1) To identify baseline predictors that dissociate between therapy responders and nonresponders, 2) to identify predictors of degree of treated recovery in therapy responders, and 3) to examine the generalizability of predictors identified under Aims 1 and 2 in randomly selected subsamples of study participants.

Method: Stroke survivors (N = 102; 43 females; age = 60.5y +/- 11.0y) with chronic aphasia (>12m post-stroke) were recruited as part of a multisite trial. …

Neural Synchrony During Naturalistic Language Perception In Listeners With Aphasia, Lisa Johnson Norris

Theses and Dissertations

Neural synchrony across listeners during language processing has been found to be associated with successful comprehension in neurotypical adults. At initial presentation of auditory-visual stimuli, neural responses appear to oscillate in different rhythms across brain regions. As the stimulus progresses, the time course of neural activity synchronizes across listeners, particularly in primary auditory and visual processing regions. This phenomenon, which we refer to as ‘neural entrainment,’ has been observed in neurotypical individuals attending to the same stimulus. Neural synchrony occurs due to the inherent neural response elicited by a stimulus and has been shown to be consistent across participants in …

Correlations Between Cognitive Pause Patterns And Listener Perceptions Of Communicative Effectiveness And Likeability For People With Aphasia, Heidi Raylene Mcconaghie

Theses and Dissertations

A prevalent feature of typical spontaneous speech are speech pauses. Longer speech pauses, known as cognitive pauses, occur in typical speech and are indicative of higher-level cognitive processes. Atypical cognitive pauses, however, are prevalent in the speech of people with aphasia consequent to their communication disorder. Research has shown that these atypical pauses may contribute to negative listener perceptions. This study aimed to determine the influence of atypical speech pause on listener perceptions of communicative effectiveness and speaker likeability. Specifically, this study evaluated the relationship between listener ratings of communicative effectiveness and likeability and acoustic measures of between-utterance pause duration, …

The Influence Of Pause On Listeners' Perceptions In Speech Of People With Aphasia, Emily Wright

Theses and Dissertations

The purpose of this study was to examine how varying pause lengths in speech of people with aphasia (PWA) influences listeners' perceptions. The study specifically assesses listeners' perceptions of communicative effectiveness and speaker likability. Speech samples from six people with nonfluent or fluent aphasia were obtained from a previous study conducted by Harmon (2018). The speech samples were modified to create four sets of stimuli, including the original recordings, normalized within utterance pauses, normalized between utterance pauses, and normalized for both within and between utterance pauses. Forty listeners rated each of the speech samples based on the perceived communicative effectiveness …

The participants included 40 professionals and 5 parents from the Rio Grande Valley. Data was collected via an online survey. These findings will not only provide fundamental knowledge but will allow for breaking the silence on the topic of bilingualism in the field of ASD. Therefore, the outcome of this research is to expand the literature for both parents and professionals, in order for them to make informed decisions about this population, and to encourage the development of bilingual services and …

Effects Of Personal Fm System Use During Phonological Awareness Instruction For Children At Risk For Dyslexia, Gabriella Rose Reynolds

Theses and Dissertations

Students with reading impairments, including dyslexia, account for the largest proportion of students receiving special education services in the United States (NCES, 2016). Developmental dyslexia is characterized by slow and inaccurate word decoding (Lyon et al., 2003). This word decoding difficulty results from deficits in phonological awareness, a sound-based skill (Swan & Goswami, 1997). Classrooms are known to have high levels of background noise and are inconsistent with recommendations for optimal listening (Picard & Bradley, 2001) or accepted standards (ASHA, n.d.). Furthermore, degraded acoustic conditions have been related to poorer performance on speech-recognition tasks even for children with normal hearing …

Serving Culturally And Linguistic Students Identified With A Communication Disability In The K-12 Educational Environments, Lashell Dauterman

Theses and Dissertations

As more and more students enter public schools with culturally and linguistically diverse backgrounds that require services under the Individuals with Disabilities Education Act, facilitators must be more sensitive to the needs, especially in the area of communication. Augmentative and alternative communication devices and other assistive technology are required by law to be utilized with individuals identified as disabled. However, due to the challenges that exist in properly identifying and implementing intervention plans for children who require services as English language learners and special education, communication needs are often misidentified or not provided. Another issue that exists is the lack …

Antisaccade Performance As A Measure Of Executive Dysfunction In Women With The Fmr1 Premutation, Lyndsay Schmitt

Theses and Dissertations

Women with the FMR1 premutation appear to be at increased risk for executive dysfunction. Findings in this regard have been mixed, leading to controversy surrounding the executive phenotype. Inhibitory deficits have been a more consistently documented component of this cognitive profile (Klusek et al., 2020; Shelton et al., 2014). This study aimed to clarify the executive phenotype through use of the antisaccade task, a well referenced eye-tracking paradigm that targets oculomotor inhibition and motor control and imposes time constraints that may increase sensitivity to executive deficits in women with the FMR1 premutation. The effects of aging were examined in both …

Narrative Language Among Mothers With The Fmr1 Premutation And Mothers Of Children With Autism Spectrum Disorder, Sara Mousavi

Theses and Dissertations

Difficulties with pragmatic language are known language traits among women with the FMR1 premutation and within the broad autism phenotype (BAP). Our study investigated the narrative cohesion and story grammar organization of spontaneously generated stories produced by mothers with the FMR1 premutation, mothers of children with ASD, and mothers of typically developing children. No group differences were observed in story grammar, overall quality, or frequency of use of temporal devices. But both the mothers of children with ASD and mothers with the FMR1 premutation committed reference errors at a significantly higher frequency than mothers in the control group. This study …
