Asymmetric Event-Related Potential Priming Effects Between English Letters And American Sign Language Fingerspelling Fonts, Zed Sevcikova Sehyr, Katherine J. Midgley, Karen Emmory, Phillip J. Holcomb

Communication Sciences and Disorders Faculty Articles and Research

Letter recognition plays an important role in reading and follows different phases of processing, from early visual feature detection to the access of abstract letter representations. Deaf ASL–English bilinguals experience orthography in two forms: English letters and fingerspelling. However, the neurobiological nature of fingerspelling representations, and the relationship between the two orthographies, remains unexplored. We examined the temporal dynamics of single English letter and ASL fingerspelling font processing in an unmasked priming paradigm with centrally presented targets for 200 ms preceded by 100 ms primes. Event-related brain potentials were recorded while participants performed a probe detection task. Experiment 1 examined …

Signing To Success: Developing Effective Asl Curricula In Secondary Public Education, Claire Sutterer

Undergraduate Research Symposium

This study aims to investigate the history of American Sign Language (ASL) in public schools, analyze where ASL education is today, and provide potential solutions to improving the quantity and quality of ASL classes within public high schools. A significant body of research focusing on preK-2nd grade students and research with primary concentration on students who are Deaf or hard of hearing has already been developed. However, developing effective methods for teaching ASL to hearing people is a relatively new and under researched area. ASL was not officially recognized as a language until the 1950s. It wasn’t until 2011 that …

American Sign Language Interpreting For D/Deaf Individuals With Disabilities: A Qualitative Study And Practical Guide, Emily Mason

Senior Honors Theses

American Sign Language (ASL) interpreting for d/Deaf individuals with disabilities (DWD) is a complex task, and one which lacks an adequate research-base to inform best practices. Using the foundation of existing literature on closely related topics such as the field of ASL interpreting, educational interpreting, education of DWD individuals, and research about specific disabilities occurring with d/Deafness, I compiled a literature review and created a theoretical conceptual framework concerning this topic. In further investigation of this subject, I also conducted a qualitative study through online questionnaires sent out by email to ASL interpreters located through snowball sampling. The data collected …

A Data-Driven Approach To The Semantics Of Iconicity In American Sign Language And English, Bill Thompson, Marcus Perlman, Gary Lupyan, Zed Sevcikova Sehyr, Karen Emmory

Communication Sciences and Disorders Faculty Articles and Research

A growing body of research shows that both signed and spoken languages display regular patterns of iconicity in their vocabularies. We compared iconicity in the lexicons of American Sign Language (ASL) and English by combining previously collected ratings of ASL signs (Caselli, Sevcikova Sehyr, Cohen-Goldberg, & Emmorey, 2017) and English words (Winter, Perlman, Perry, & Lupyan, 2017) with the use of data-driven semantic vectors derived from English. Our analyses show that models of spoken language lexical semantics drawn from large text corpora can be useful for predicting the iconicity of signs as well as words. Compared to English, ASL has …

The Perceived Mapping Between Form And Meaning In American Sign Language Depends On Linguistic Knowledge And Task: Evidence From Iconicity And Transparency Judgments, Zed Sevcikova Sehyr, Karen Emmorey

Communication Sciences and Disorders Faculty Articles and Research

Iconicity is often defined as the resemblance between a form and a given meaning, while transparency is defined as the ability to infer a given meaning based on the form. This study examined the influence of knowledge of American Sign Language (ASL) on the perceived iconicity of signs and the relationship between iconicity, transparency (correctly guessed signs), ‘perceived transparency’ (transparency ratings of the guesses), and ‘semantic potential’ (the diversity (H index) of guesses). Experiment 1 compared iconicity ratings by deaf ASL signers and hearing non-signers for 991 signs from the ASL-LEX database. Signers and non-signers’ ratings were highly correlated; however, …

Implicit Co-Activation Of American Sign Language In Deaf Readers: An Erp Study, Gabriela Meade, Katherine J. Midgley, Zed Sevcikova Sehyr, Phillipp J. Holcomb, Karen Emmorey

Communication Sciences and Disorders Faculty Articles and Research

In an implicit phonological priming paradigm, deaf bimodal bilinguals made semantic relatedness decisions for pairs of English words. Half of the semantically unrelated pairs had phonologically related translations in American Sign Language (ASL). As in previous studies with unimodal bilinguals, targets in pairs with phonologically related translations elicited smaller negativities than targets in pairs with phonologically unrelated translations within the N400 window. This suggests that the same lexicosemantic mechanism underlies implicit co-activation of a non-target language, irrespective of language modality. In contrast to unimodal bilingual studies that find no behavioral effects, we observed phonological interference, indicating that bimodal bilinguals may …

An Alternative View Of Education For Deaf Children: Part Ii, Lil Brannon, Sue Livingston

Publications and Research

How might deaf children acquire one of the primary goals of education literacy in English? This article suggests that literacy in English as well as knowledge of the English language can be acquired concomitantly through developmental reading and writing activities that reflect principles of first language acquisition if students bring to these activities relatable experiences which they have already linguistically represented. Such activities engage students in reading and writing where content and context support them in their attempts to actively understand and convey meaning in English. The end product of, rather than the prerequisite for, this meaningful reading and writing …

An Alternative View Of Education For Deaf Children: Part I, Sue Livingston

Publications and Research

Quigley and Kretschmer (1982) asserted that the primary goal of education for deaf children should be literacy in English. This article presents an alternative view that there be two primary goals: (a) thinking and learning through the development of meaning-making and meaning-sharing capacities and (b) the acquisition of literacy in English. In this article, the first of these goals is viewed as the more fundamental since it facilitates the acquisition of knowledge while it simultaneously serves as the prerequisite for the acquisition of literacy in English. Because neither direct language instruction nor the exclusive use of English in sign will …

Levels Of Development In The Language Of Deaf Children: Asl Grammatical Processes, Signed English Structures, Semantic Features, Sue Livingston

Publications and Research

This study describes the spontaneous sign language of six deaf children (6 to 16 years old) of hearing parents, who were exposed to Signed English when after the age of six they first attended a school for the deaf. Samples of their language taken at three times over a 15-month period were searched for processes and structures representative or not representative of Signed English. The nature of their developing semantics was described as the systematic acquisition of features of meaning in signs from selected lexical categories (kinship terms, negation, time expression, wh-questions, descriptive terms, and prepositions/conjunctions).

Processes not representative of …
