Special Education: Inclusion And Exclusion In The K-12 U.S. Educational System, Erik Brault

Dissertations

The U.S. Department of Education defines students with disabilities as those having a physical or mental impairment that substantially limits one or more life activities. Previous research has found that students with disabilities placed in inclusive environments perform better academically and socially compared to students with disabilities who are placed in segregated environments. Yet, we know that inclusion in K-12 general education classrooms across the country is not consistently implemented.

The purpose of this study was to better understand the effects, if any, of general education high school teachers’ personal and professional experiences and knowledge on their attitudes toward educating …

Benefit Of Visual Speech Information For Word Comprehension In Post-Stroke Aphasia, Anna Krason, Gabriella Vigliocco, Marja-Liisa Mailend, Harrison Stoll, Rosemary Varley, Laurel J. Buxbaum

Moss-Magee Rehabilitation Papers

Aphasia is a language disorder that often involves speech comprehension impairments affecting communication. In face-to-face settings, speech is accompanied by mouth and facial movements, but little is known about the extent to which they benefit aphasic comprehension. This study investigated the benefit of visual information accompanying speech for word comprehension in people with aphasia (PWA) and the neuroanatomic substrates of any benefit. Thirty-six PWA and 13 neurotypical matched control participants performed a picture-word verification task in which they indicated whether a picture of an animate/inanimate object matched a subsequent word produced by an actress in a video. Stimuli were either …

Botulinum Toxin For Abductor Type Spasmodic Dysphonia: A Systematic Review, Keyona Sutton

Honors Theses

A systematic review was conducted to show that BTX (Botulinum Toxin) is the most effective treatment for Abductor Spasmodic Dysphonia (ABSD). There were a total of 117 records screened for inclusion in this review. After the initial screening, there were seven successive rounds of screening for eligibility. This process produced a total of three eligible records that met the following conditions: patients presented with spastic abduction, electromyography BTX type A injection into the posterior cricoarytenoid muscle, and measurement of results with acoustic dimensions. After surveying all eligible studies, it was concluded that BTX is an effective treatment for ABSD. Every …

Dynamic Assessment Of Aac Verb Symbols For Children With Autism Spectrum Disorder, Valerie Prieto, Cindy Gevarter, Cathy Binger, Mary Hartley

Speech and Hearing Sciences ETDs

This study used dynamic assessment (DA) with graduated prompting to evaluate whether preschool-aged children with autism spectrum disorder (ASD) demonstrated learning potential with verb-based augmentative alternative communication (AAC) symbols. Four participants completed DA sessions across three instructional conditions: (a) requesting actions embedded in play, (b) labeling actions embedded in play, and (c) labeling actions presented via video. Performance across these conditions along with a control condition was compared using an adapted multielement single-case design. Three participants demonstrated learning in at least two instructional conditions, and only one showed progress in the control condition. Overall, participants initially required less cueing to …

Telepractice-Based Language Intervention Training For Parents Of Children With Autism Spectrum Disorders, Sarah Bryan

Honors Theses

This study closely examined the progression and fidelity of strategy implementation of parents undergoing an ASD language intervention training program. This instructional, interactive program was designed for parents of children with autism, thus catering to the needs of participants involved. This study assessed the use of parent comments and redirects, two kinds of parent strategies, during each parent-child interaction to provide more information about the impact of training sessions. The researchers hypothesized that by the end of training, parent participants would increase their fidelity of strategy implementation, increase their use of comments rather than redirects, and employ more open-ended questions …

An Examination Of The Research Addressing Evidence-Based Communication Approaches For Students With Autism, Sydni Kaye Mcatee

Honors Theses

The meta-analysis examines scholarly articles regarding research on evidence-based communication for students with Autism Spectrum Disorder. More specifically, this research involves different forms of Alternative and Augmentative Communication. This form of communication is used without a voice. A variety of interventions for Manual Signing (MS), Speech Generating Devices (SGD), and Picture Exchange Communication Systems (PECS) are reviewed within the research study. The purpose of this research is to define which evidence-based Alternative and Augmentative Communication (AAC) interventions are most effective for children with Autism. More specifically, determining which form of communication can help lead children to more expressive language and …

Verb Tense Production Differences Across Various Discourse Tasks In People With Fluent And Nonfluent Aphasia, Madeline Ann Zurbrugg

Honors Theses

Background: Fluent and nonfluent aphasia are both seen to exhibit varying degrees of morphosyntactic difficulties, with particular difficulties in verb tense production. There is disagreement regarding why tense is particularly impaired, which type of aphasia is more impaired and why, and whether some tense forms are more impaired than others. There is also evidence that language elicitation tasks affect language production measures because they require different linguistic and cognitive processes. This is likely also true for verb tense production. To date, no studies have examined discourse elicitation task effect on verb tense production in both fluent and nonfluent aphasia. The …

The Existence Of Stuttering-Like Disfluencies In American Sign Language, Katherine King

Honors Theses

For over a century, data have documented fluency disorders and stuttering-like disfluencies (SLDs) in multiple expressive modalities outside of speech, including musical expression, writing, and American Sign Language (ASL). The presence of SLDs in multiple expressive modalities presents the argument that SLDs are not limited to speech. This study specifically surveys fluent ASL signers relative to SLDs, analyzes SLD manifestations, and documents specific examples of stuttering behaviors in ASL.

This study analyzes SLD manifestations in ASL by conducting a survey developed from all known research within the SLD paradigm. Based on all previous research, SLD manifestations are categorized and represented …

The Effects Of Calmer On The Quality Of Life In Adults With Level 1 Autism Spectrum Disorder, Madilyn Morris

Honors Theses

Level 1 autism spectrum disorder (ASD) is a high-functioning neurodevelopmental disorder (Hodges et al., 2020; Hosseini & Molla, 2023). Several features of level 1 ASD negatively impact quality of life (QOL), and auditory sensitivity (specifically hyperacusis) is one of the most prevalent and disabling features (Danesh et al., 2015, 2021; Kuiper et al., 2019; Williams et al., 2021). Hyperacusis significantly impacts QOL in the level 1 ASD population, as current hyperacusis treatment strategies often result in various forms of social isolation (Adams et al., 2021; Danesh et al., 2015; Neave-DiToro et al., 2021).

The Effect Of Microglial Cell Dysfunction On Multi-Modal Pre-Pulse Inhibition, Michelle Besser

Dissertations, 2020-current

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by persistent deficits in social communication, restricted behaviors, and executive functioning deficits. Mutations in fractalkine signaling, particularly in CX3CR1, in the brain have been linked to ASD and other neurodevelopmental disorders. This investigation examined wild-type mice and mice with one or two copies of mutated CX3CR1 and their uni-modal (auditory and somatosensory) and multi-modal (combined) pre-pulse inhibitions (PPI). PPI is an unconditioned response – a decrement in the acoustic startle reflex when the mouse detects a non-startling stimulus presented a few hundred ms before the startling sound. In this study, the …

Impact Of Diabetes Mellitus On Vestibular Function: A Scoping Review, Ellen M. Jones

Dissertations, 2020-current

Diabetes mellitus (DM) encompasses a group of metabolic diseases that result in high blood sugar (i.e., hyperglycemia). By 2030, it is anticipated that 578 million adults worldwide will have DM, with this number growing at a faster rate in developed areas of the world.^[27] If left uncontrolled, DM can cause considerable damage to several areas of the body, including the heart, kidneys, nerves, and ears. When focusing exclusively on the ears, there has been markedly less research on the vestibular system when compared to the auditory system, even though DM is a known risk factor for falling. The purpose …

Magnitude Estimates Of Angular Motion: Perception Of Speed And Spatial Orientation Across Visual And Vestibular Modalities, Erin Hernon

Dissertations, 2020-current

Both the vestibular system and optokinetic system generate conjugate eye movements in response to either movement of the head or movement of the visual surround. Both systems help to maintain gaze stability. While the VOR is most sensitive to input frequencies above .2 Hz, the optokinetic system helps maintain gaze stability at lower frequencies. Previous research on perceptual thresholds across the two sensory modalities shows that there are frequency-dependent differences between vestibular and visual perception. The purpose of this study is to extend previous vestibular psychophysics work by 1) comparing magnitude estimates from vestibular stimulation to visual stimulation across multiple …

Age-Related Decline In Neural Synchrony And The Ffr, Haley Szabo

Dissertations, 2020-current

It is a known phenomenon that speech understanding in background noise declines with advancing age. Although there is ample evidence of behavioral measures declining with age, there is less physiologic evidence. This study hypothesizes that the FFR will be degraded with advancing age, consistent with poorer phase locking. This is hypothesized to be present even in people with audiograms within normal limits. A second hypothesis is that middle-aged adults will have degraded neural representation as frequency increases, compared to a younger normal hearing group which will have better high frequency neural representation than the middle-aged group. Subjects were divided into …

Reality Of Counseling In Pediatric Audiology Clinical Practice, Lara Leggio

Dissertations, 2020-current

The overwhelming nature of hearing loss identification often causes families to experience grief and confusion. Children as young as nine months old with severe hearing loss have the option to undergo cochlear implantation (CI) surgery with the hopes of restoring normal hearing. Pediatric audiologists accompany families through the identification of hearing loss and the learning process that coincides with this surgery. Despite knowledge that parents of children with communication disabilities will experience a sense of loss and have moderate to severe cyclic emotional reactions, little is known about how audiologists manage the emotional needs of families, if they feel prepared …

Assessing Word Recognition In Infants With A History Of Chronic Otitis Media, Sarah Wright

Dissertations, 2020-current

Otitis media (OM) is a common ear-related disorder diagnosed in children that can cause a temporary conductive hearing loss. The fluctuating hearing loss may alter auditory processing which may interfere with language development while impacting quality of life for infants and their caregivers (Homøe et al., 2019). In several languages, eleven-month-old infants have shown a preference for familiar words over unfamiliar words using the head-turn preference paradigm. This study examines the effect of chronic OM on the preference for familiar or unfamiliar words in eleven-month-old infants. Fourteen eleven-month-old infants (mean age 344 days) with three or more diagnosed ear infections …

Role Of Emg Monitoring On Cvemp Testing In Preschool Age Children, Brenna Murray

Dissertations, 2020-current

While cervical vestibular evoked myogenic potential (cVEMP) testing has largely been studied and practiced on the adult population, less is known about the best practices for performing cVEMPs on a pediatric population, especially in young children under the age of 5 years. Further, very young children (i.e., 2-3 years) often prefer to sit with their caregiver during the testing, yet there is very little data on how much electromyographic (EMG) activity a child generates if in a seated position as opposed to a supine position. The purpose of this study was to assess the role of EMG on cVEMP recordings …

The Relationship Between Coping Behaviors And Misophonia Symptom Severity And Impairment, Ruth Emmon Tyson

Honors Theses

Misophonia is a complex disorder that is characterized by an extreme disliking of sounds. Individuals with misophonia may engage in anxiety-driven coping behaviors that constitute avoidance and safety behaviors. Current literature shows that while coping behavior may offer temporary relief of anxiety and distress, they can lead to persisting anxiety and avoidance of experiences. Given preliminary evidence demonstrating a link between coping behaviors and maintained or worsening symptoms, additional research is warranted to further understand the role of coping behaviors in misophonia. However, few studies have investigated the relationship between coping behaviors and maintenance or worsening of misophonia symptom severity …

Functional And Location Context Effects On Reading Sentences In Healthy Young Adults: Evidence From Eye Tracking Methods, Elizabeth Baird

Honors Theses

Spreading activation theory proves the way our brains are semantically wired to accept outside information and understand it. Previous studies have demonstrated the effects of spreading activation theory in different settings and activities. These effects are important to understand because they can be used in therapy and assessment for communication disorders. This study explores how the context of sentences affects reading time on noun targets in healthy young adults using an eye tracking method. Specifically, we compared functional and location context types and manipulated the context to be incongruent or congruent to the targets. Our research questions were (1) whether …

Multilingualism And Augmentative Alternative Communication: A Review Of The Literature, Hannah N. Lamarca, Natalie R. Andzik

Honors Capstones

Purpose: Individuals from culturally and linguistically diverse backgrounds who use Alternative and Augmentative Communication (AAC) are often offered English-only AAC systems that do not meet their language needs. Devices that host multiple languages often only offer one at a time.

Method: The authors reviewed the literature by searching relevant databases using a variety of search strings. Following our inclusionary and exclusionary criteria, 15 articles were yielded for analysis.

Results: Authors found that more than half of the included articles were discussion-based papers on AAC delivery, barriers to AAC and multilingualism, and codeswitching using AAC. The included interview studies aimed to …

Inflammatory Marker Levels Among Patients Diagnosed With Autism Spectrum Disorder And Congenital Heart Defects, Patrick Pearce, Venkateswar Venkataraman, Andrea Iannuzzelli, Jennifer Lecomte

Rowan-Virtua Research Day

Autism Spectrum Disorder (ASD) and congenital heart defects (CHD) are conditions that both confer an immense increase in standard of care, and utilization of medical resources addressing comorbidities. One shared symptom that has been consistently cited is inflammation. This review sought to explore the levels of Tumor Necrosis Factor-�� (TNF-��) and Interleukin-6 (IL-6) between patients diagnosed as having either ASD or CHD. By compiling published data containing the mean values of these two inflammatory markers within these populations, it was shown that while both have significantly elevated levels compared to a phenotypically normal demographic, there is no significant difference between …
