Sound-Category Learning And Memory Skills In Neurotypical Adults And Adults With Language-Learning Disabilities, Allison Fulcher Jun 2023

Sound-Category Learning And Memory Skills In Neurotypical Adults And Adults With Language-Learning Disabilities, Allison Fulcher

University Honors Theses

This study evaluates the impact of memory skills (procedural, declarative, and working) and sound discrimination abilities, on the ability of adults with and without Language Learning Disability (LLD) to learn two sound-category structures, one designed to be learned implicitly and the other designed to be learned explicitly. This design tests a theorized etiology for LLD, the Procedural Deficit Hypothesis (PDH), which posits that LLD is caused by selective impairments to procedural memory and implicit learning. It also serves to evaluate factors and conditions that contribute to success in second-language learning for adults, who are less neurologically suited to the task …

Use Of A Standardized Tracheostomy Patient Simulation To Evaluate Student Clinical Communication Skills, Amanda Stead, Jordan Tinsley, Kerry Mandulak, Paul Michael, Helene Deiner

Teaching and Learning in Communication Sciences & Disorders

Simulation is a valid pedagogical tool used to teach students, observe student clinical skills, and to assess clinical competencies. During the COVID-19 pandemic, a lack of medical speech-language pathology placements required graduate programs to re-examine clinical training. Simulation has proven useful in providing an alternative and safe learning modality. Standardized patients, which are one simulation modality, provide increased standardization and higher fidelity than medical manikins. This is particularly true in the context of both student learning and demonstration of clinical communication skills (CCS) within a simulated learning environment where the simulated patient can interact authentically with the student clinician. CCS …

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 …


The Effects Of Calmer On The Quality Of Life In Adults With Level 1 Autism Spectrum Disorder, Madilyn Morris May 2023

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).

However, Flare Audio markets a product (“Calmer”) …


Verb Tense Production Differences Across Various Discourse Tasks In People With Fluent And Nonfluent Aphasia, Madeline Ann Zurbrugg May 2023

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 May 2023

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 …
