Take a moment to reflect on your day to day life. Think about the conversation you have with your barista at Starbucks, the polite hellos and you’re welcomes you pass out to strangers on the street, or the sound of your best friend’s latest story. Society could not exist without language. Every person utilizes language within their own spaces and communities to establish their identities and relationships with the world around them. The Linguistic Society of America classifies sociolinguistics as the investigation of how “language use symbolically represents fundamental dimensions of social behavior and human interaction.” Broadly, sociolinguistics looks at language’s relationship to and function within society.

This study looked into the cultural competency of physicians when interacting with patients who identify themselves as part of the Deaf and Hard of Hearing community. Through the course of this paper, it was found that the language barrier between these two communities played a large role in healthcare disparities for the D/HoH community. The language and culture barrier contributed to the misconceptions that are commonly found in the hearing world about the Deaf community, including assumptions about Deaf patients' opinion on their hearing loss, the efficacy of yelling, and the notion that all Deaf people can lip read with 100% accuracy. In addition, the perspectives of both the healthcare professionals and D/HoH patients was analyzed. Finally, the efficacy of current hospitals solutions for the language barrier was evaluated, particularly the use of video interpreting in hospital settings. More lasting solutions were proposed as an extension of this study, with an emphasis on education in all field of healthcare.

As the economy becomes more technologically driven the need for people in science, technology, engineering, and mathematical (STEM) fields also increases. STEM fields have been overrun with white males. Congress has been trying to promote minority groups in these fields for thirty years with little success. One of the largest underrepresented groups is individuals with disabilities. This thesis project focuses on STEM outreach for a particular group of disabled, the deaf and hard of hearing. There is a long history of deaf and hard of hearing children being poorly educated due to actions by the hearing community. Deaf and hard of hearing children are isolated not only from other deaf individuals but from their natural language, sign language. The goal of this project is to promote better educational practices and opportunities for deaf and hard of hearing children that also encourage an interest in STEM fields and education. This goal is met through the creation of the website deafstem.com. The website promotes the ideals set by the Bill of Rights for Deaf and Hard of Hearing Children established in part by the National Association of the Deaf (NAD). These include the ideals that a deaf or hard of hearing child has the same ability and capacity for language as any other child and that language pertains to both English and American Sign Language (ASL), that the families of these children play a significant role in their success, and that these children should have access and exposure to deaf and hard of hearing adults. The website build a bridge between deaf children, their hearing family, and the deaf community while promoting STEM fields by providing ASL dictionaries for both STEM and everyday vocabulary, biographies of influential deaf adults in STEM fields, and extracurricular activities for deaf and hard of hearing children.

Language acquisition is a phenomenon we all experience, and though it is well studied many questions remain regarding the neural bases of language. Whether a hearing speaker or Deaf signer, spoken and signed language acquisition (with eventual proficiency) develop similarly and share common neural networks. While signed language and spoken language engage completely different sensory modalities (visual-manual versus the more common auditory-oromotor) both languages share grammatical structures and contain syntactic intricacies innate to all languages. Thus, studies of multi-modal bilingualism (e.g. a native English speaker learning American Sign Language) can lead to a better understanding of the neurobiology of second language acquisition, and of language more broadly. For example, can the well-developed visual-spatial processing networks in English speakers support grammatical processing in sign language, as it relies heavily on location and movement? The present study furthers the understanding of the neural correlates of second language acquisition by studying late L2 normal hearing learners of American Sign Language (ASL). Twenty English speaking ASU students enrolled in advanced American Sign Language coursework participated in our functional Magnetic Resonance Imaging (fMRI) study. The aim was to identify the brain networks engaged in syntactic processing of ASL sentences in late L2 ASL learners. While many studies have addressed the neurobiology of acquiring a second spoken language, no previous study to our knowledge has examined the brain networks supporting syntactic processing in bimodal bilinguals. We examined the brain networks engaged while perceiving ASL sentences compared to ASL word lists, as well as written English sentences and word lists. We hypothesized that our findings in late bimodal bilinguals would largely coincide with the unimodal bilingual literature, but with a few notable differences including additional attention networks being engaged by ASL processing. Our results suggest that there is a high degree of overlap in sentence processing networks for ASL and English. There also are important differences in regards to the recruitment of speech comprehension, visual-spatial and domain-general brain networks. Our findings suggest that well-known sentence comprehension and syntactic processing regions for spoken languages are flexible and modality-independent.

For this project the main goal was to create a curriculum aimed at fourth grade students. This curriculum was intended to introduce them to different forms of communication, and teach them the skills, attitudes, behavior, and knowledge that would enable them to be able to communicate and interact better with a wide range of people with different types of communication styles. American Sign Language was used for this curriculum as an example of an alternative communication method. The project included developing teaching materials and lessons which made up the curriculum, after that this curriculum was implemented with 11 fourth grade students.

With higher than normal levels of cardiovascular disease, diabetes, obesity, and sexually transmitted diseases within the Deaf community, it is clear that the current level of medical care is failing. This can stem from many different issues, from the mistrust of doctors to the fact that scientific education in the Deaf community is introduced at a later time in comparison to the hearing population. Similarly, there is a distinct lack of Deaf and hard of hearing medical staff. All of this culminates in the fact that the system needs to change. The addition of more Deaf staff in the medical environment, more staff interpreters, and doctors that have experience with the Deaf community engenders the metamorphosis of this group from unhealthy to healthy. Extra exposure for doctors during clinical rotations to deaf patients as well as training in Deaf Culture will further increase the comfort level of Deaf community members utilizing health services. As a result, the overall state of medical care for the Deaf population will improve with these modifications to the current system.
