The neurobiology of sentence comprehension: an fMRI study of late American Sign Language acquisition
Description
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.

Description
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.

Description
Despite the vast research and attention given to education, little is known about teacher preparation to raise the quality of education for the honors students. There is an apparent disconnect from the honors students at Arizona State University and the education major. This study uncovers the perspective of the honors students who are majoring in education. Qualitative data was collected using one-on-one interviews. Results showed that all seven interviewed subjects were not satisfied with the education they were receiving as an honors education major.

Description
This thesis is a two-part theatre and literature project on The Importance of Being Earnest by Oscar Wilde. The research component will consist of gathering information from the origins of this play in writing and in production to further understand my knowledge of the time it was written in and how it has been interpreted over the years. The theatrical elements will come as I direct and produce my own production of the play, and compare my research of Wilde's play and past productions to my own directorial decisions in attempt to make a successful student performed play.
