Orthographic Representations In American Sign Language Fingerspelling, Zed Sehyr, Lauren Fillet, Kiana Billot-Vasquez, Emily Saunders, Karen Emmorey

Communication Sciences and Disorders Faculty Articles and Research

This study examined fingerspelling accuracy and error patterns in deaf American Sign Language (ASL) signers and written spelling in hearing English speakers to investigate how orthographic representations are shaped by phonological, visual, and motor encoding strategies. Deaf participants (n = 39) completed a fingerspelling repetition task, while hearing participants (n = 35) completed a written dictation task using the same word and pseudoword stimuli. While overall accuracy did not differ significantly between groups, deaf participants exhibited qualitatively distinct error patterns, including higher rates of deletions and transpositions, compared to hearing participants who made more substitution errors. Deaf participants also produced …

Against Audiepistemic Injustice: Claiming Deaf Futurity, Pamela R. Conley

Antioch University Dissertations & Theses

This dissertation proposes a new theoretical framework: Audiepistemic Injustice (AEI). Expanding upon existing theories of epistemic injustice (EI), I identify AEI as the systemic marginalization and dismissal of deaf ways of knowing. AEI is a multidimensional phenomenon rooted in the nineteenth century, when auditory and linguistic biases became codified across education, law, and literature. This interdisciplinary study interrogates three nineteenth-century literary narratives as primary case studies to examine AEI: (1) Ivan Turgenev’s “Mumu,” (2) Guy de Maupassant’s “The Deaf Mute,” and (3) Abigail Bradley Hyde’s “The Deaf and Dumb Child: A True Narrative.” I synthesize these literary works with legal …

Terminating Pregnancies In Boccaccio, Anne C. Leone

Languages, Literatures, and Linguistics - All Scholarship

Analyzing examples from the Decameron (1349-51), De mulieribus claris (1361), and the Corbaccio (1365), I argue that Boccaccio (1313-75) demonstrates an awareness of theological, legal and medical opinions on abortion and contraception at the time. However, he is more attuned to the practical concerns of pregnancy than are many of his contemporaries. Acknowledging the variety of situations facing pregnant people and some parts of their lived experience that were ignored by many religious and legal authorities, Boccaccio highlights a disconnection between theory and practice, and thereby raises questions about the limits of abstract knowledge in the face of practical concerns.

Neural Associations Between Fingerspelling, Print, And Signs: An Erp Priming Study With Deaf Readers, Brittany Lee, Sofia E. Ortega, Priscilla M. Martinez, Katherine J. Midgley, Phillip J. Holcomb, Karen Emmorey

Communication Sciences and Disorders Faculty Articles and Research

Fingerspelling is a leading predictor of reading ability for deaf people who use a signed language, but few neuroimaging studies have examined how it supports reading. We used event-related potentials to investigate how fingerspelled words prime printed words. Twenty-four skilled deaf adult readers completed a Go/No-Go task while viewing printed English word targets following related and unrelated primes in one of three conditions: printed English words, American Sign Language (ASL) signs, and fingerspelled words. N400 priming effects were strong across all three conditions. Early N400 effects were similar for printed word primes and fingerspelled word primes, suggesting shared orthographic representations. …

Deaf-Centric Expression Of Biblical Language And Themes, Grace M. Tang

Senior Honors Theses

Christianity contains complicated language and concepts that many individuals can struggle to express in American Sign Language (ASL) in ways that resonate with the Deaf community. Accessibility for the Deaf extends far beyond the translation of words into signs, requiring recontextualization to fit a Deaf lens and adaptation of communication methods to match the oral tradition and Deaf culture. This qualitative study evaluates how the hearing-centered language and themes of the Bible can be effectively portrayed to Deaf audiences through comprehensive interviews with three Deaf Christian pastors and three hearing Christian interpreters. This research found that Deaf churches allow for …

Iconicity As An Organizing Principle Of The Lexicon, Erin E. Campbell, Zed Sevcikova Sehyr, Elana Pontecorvo, Ariel Cohen-Goldberg, Karen Emmorey, Naomi Caselli

Communication Sciences and Disorders Faculty Articles and Research

The view that words are arbitrary is a foundational assumption about language, used to set human languages apart from nonhuman communication. We present here a study of the alignment between the semantic and phonological structure (systematicity) of American Sign Language (ASL), and for comparison, two spoken languages—English and Spanish. Across all three languages, words that are semantically related are more likely to be phonologically related, highlighting systematic alignment between word form and word meaning. Critically, there is a significant effect of iconicity (a perceived physical resemblance between word form and word meaning) on this alignment: words are most likely to …

Exploring Essentialization, Stereotyping, And Forms Of Dehumanization In American Sign Language, Madeline Haefele

Honors Scholar Theses

This paper investigates the philosophical implications of evolving and removing certain signs in American Sign Language (ASL), with a focus on those considered problematic due to their potential to perpetuate stereotypes or essentialism. Through an analysis of signs for words such as Jewish, Chinese, Japanese, Korean, and Black, this study explores how language shapes and reflects social attitudes, particularly within the Deaf community. The research situates these signs within philosophical frameworks, identifying their potential contributions to social essentialism, prejudice, or forms of dehumanization.

While addressing the challenges of limited first-hand accounts from Deaf individuals, the …

The Deaf Experience In National Parks With An Emphasis On Rocky Mountain National Park, Madeline Dannewitz

Undergraduate Honors Theses

This research investigated the experiences of Deaf visitors to the Rocky Mountain National Park (RMNP). The little research available focuses on how the National Park Service and its workers interact with Deaf people. Conversely, this study investigated the experiences of Deaf people and their perspective regarding interacting with the park and its members. A study regarding Deaf visitors in Yosemite National Park found that many were invisible to its employees. The desire from the Deaf community and lack of research shows the significance of this study. This analysis is crucial to the human experience as quality of life is improved …

Exploring Strategies For Modeling Sign Language Phonology, Lee Kezar, Riley Carlin, Tejas Srinivasan, Zed Sehyr, Naomi Caselli, Jesse Thomason

Communication Sciences and Disorders Faculty Articles and Research

Like speech, signs are composed of discrete, recombinable features called phonemes. Prior work shows that models which can recognize phonemes are better at sign recognition, motivating deeper exploration into strategies for modeling sign language phonemes. In this work, we learn graph convolution networks to recognize the sixteen phoneme “types” found in ASL-LEX 2.0. Specifically, we explore how learning strategies like multi-task and curriculum learning can leverage mutually useful information between phoneme types to facilitate better modeling of sign language phonemes. Results on the Sem-Lex Benchmark show that curriculum learning yields an average accuracy of 87% across all phoneme types, outperforming …

Enrico Pea And The Awareness Of Never-Ending Detachment (Alexandria, Egypt 1896–1914), Stefano Giannini

Languages, Literatures, and Linguistics - All Scholarship

This chapter analyzes the postcolonial discourse in Italy, through the voice of the novelist and playwright Enrico Pea (1881–1958). Living outside of Italy, Pea gained a unique awareness of the notion of multi-ethnic societies, of the concepts of nationality, borders, and boundaries. Alexandria, Egypt, is Pea’s referential space. It is a center, and at the same time, a marginal place. Alexandrea ad Egyptum, that is, the door to Egypt, as it was known in antiquity, this city brought together Arab and European artistic experiences that converged on, and were triggered by, its multicultural profile. The history of political exile …

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 …

Improving Sign Recognition With Phonology, Lee Kezar, Jesse Thomason, Zed Sevcikova Sehyr

Communication Sciences and Disorders Faculty Articles and Research

We use insights from research on American Sign Language (ASL) phonology to train models for isolated sign language recognition (ISLR), a step towards automatic sign language understanding. Our key insight is to explicitly recognize the role of phonology in sign production to achieve more accurate ISLR than existing work which does not consider sign language phonology. We train ISLR models that take in pose estimations of a signer producing a single sign to predict not only the sign but additionally its phonological characteristics, such as the handshape. These auxiliary predictions lead to a nearly 9% absolute gain in sign recognition …

Starved For Knowledge: The Effect Of Language Deprivation And “Mainstream” Education On Deaf Accessibility To The United States Education System, Katherine Arpino

Honors Scholar Theses

The prevalence of language deprivation in deaf and hard of hearing youth makes the United States public education system fundamentally inaccessible to that portion of the population. Previous research has demonstrated that depriving prelingually deaf children of an accessible, visual language during the critical language acquisition period has long-term effects on their reading comprehension, mental health, social development, and cognitive development (Friedman and Rusoe, 2015; Hall et al., 2019; Cheng et al., 2019; Hall, 2017). Furthermore, the lack of bilingual-bimodal education (or purely signed education) in the United States public education system sets deaf children up for failure, as they …

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 …

An Interactive Visual Database For American Sign Language Reveals How Signs Are Organized In The Mind, Zed Sevcikova Sehyr, Ariel Goldberg, Karen Emmory, Naomi Caselli

Communication Sciences and Disorders Faculty Articles and Research

"We are four researchers who study psycholinguistics, linguistics, neuroscience and deaf education. Our team of deaf and hearing scientists worked with a group of software engineers to create the ASL-LEX database that anyone can use for free. We cataloged information on nearly 3,000 signs and built a visual, searchable and interactive database that allows scientists and linguists to work with ASL in entirely new ways."

The Asl-Lex 2.0 Project: A Database Of Lexical And Phonological Properties For 2,723 Signs In American Sign Language, Zed Sevcikova Sehyr, Naomi Caselli, Ariel M. Cohen-Goldberg, Karen Emmory

Communication Sciences and Disorders Faculty Articles and Research

ASL-LEX is a publicly available, large-scale lexical database for American Sign Language (ASL). We report on the expanded database (ASL-LEX 2.0) that contains 2,723 ASL signs. For each sign, ASL-LEX now includes a more detailed phonological description, phonological density and complexity measures, frequency ratings (from deaf signers), iconicity ratings (from hearing non-signers and deaf signers), transparency (“guessability”) ratings (from non-signers), sign and videoclip durations, lexical class, and more. We document the steps used to create ASL-LEX 2.0 and describe the distributional characteristics for sign properties across the lexicon and examine the relationships among lexical and phonological properties of signs. Correlation …

The improv language exercises in this compilation are chosen from the experience I gathered 20 years ago, but also from the amazing work of Lauren Esposito and Scranton Improv & Comedy that have been more real than anything else to me this past summer, and from Jim Ansaldo, who taught me how to structure improv exercises online. They are organized by level, referring to the Common European Framework of References for Languages. That means, A1 exercises can be conducted at the beginners level but also at all other higher levels, but B2 exercises should not be imposed upon beginners or …

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 …

Cross-Linguistic Metaphor Priming In Asl-English Bilinguals: Effects Of The Double Mapping Constraint, Franziska Schaller, Brittany Lee, Zed Sevcikova Sehyr, Lucinda O'Grady Farnady, Karen Emmorey

Communication Sciences and Disorders Faculty Articles and Research

Meir’s (2010) Double Mapping Constraint (DMC) states the use of iconic signs in metaphors is restricted to signs that preserve the structural correspondence between the articulators and the concrete source domain and between the concrete and metaphorical domains. We investigated ASL signers’ comprehension of English metaphors whose translations complied with the DMC (Communication collapsed during the meeting) or violated the DMC (The acid ate the metal). Metaphors were preceded by the ASL translation of the English verb, an unrelated sign, or a still video. Participants made sensibility judgments. Response times (RTs) were faster for DMC-Compliant sentences …

A Lexical Frequency Analysis Of Irish Sign Language, Robert G. Smith, Markus Hofmann

Articles

Word frequency has a significant impact on language acquisition and fluency. It is often a point of reference for the teaching and assessing of a language and indeed, as a control for psycholinguistic studies. This paper presents the results of the first objective frequency analysis of lexical tokens from the Signs of Ireland corpus. We investigate the frequency of fully lexical, partly lexical and non-lexical signs in Irish Sign Language as they are presented in the corpus. We confirm the accuracy of the lexical gloss frequency data with a supplementary corpus subset that is tagged for grammatical class and additional …

I Saw The Signs: The Role Of American Sign Language In Preventing Violence Against Deaf Youth, Tolu Ojuola

Senior Honors Theses

The American Deaf community, comprised of approximately 500,000 people, has developed into a sociolinguistic, cultural community with American Sign Language (ASL) at its center. ASL is the autonomous language of Deaf individuals in America complete with its own grammar, orthography, syntax, and morphology. ASL is capable of conveying complex emotions and abstract ideas. However, most deaf children remain unable to express their innermost feelings because they live in homes with hearing parents who do not speak their language. For many deaf children, this is their first experience with isolation, but it is one they will grow familiar with as they …

Unique N170 Signatures To Words And Faces In Deaf Asl Signers Reflect Experience-Specific Adaptations During Early Visual Processing, Zed Sevcikova Sehyr, Katherine J. Midgley, Phillipp J. Holcomb, Karen Emmorey, David C. Plaut, Marlene Behrmann

Communication Sciences and Disorders Faculty Articles and Research

Previous studies with deaf adults reported reduced N170 waveform asymmetry to visual words, a finding attributed to reduced phonological mapping in left-hemisphere temporal regions compared to hearing adults. An open question remains whether this pattern indeed results from reduced phonological processing or from general neurobiological adaptations in visual processing of deaf individuals. Deaf ASL signers and hearing nonsigners performed a same-different discrimination task with visually presented words, faces, or cars, while scalp EEG time-locked to the onset of the first item in each pair was recorded. For word recognition, the typical left-lateralized N170 in hearing participants and reduced left-sided asymmetry …

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, …

Second Language Acquisition Of American Sign Language Influences Co-Speech Gesture Production, Jill Weisberg, Shannon Casey, Zed Sevcikova Sehyr, Karen Emmorey

Communication Sciences and Disorders Faculty Articles and Research

Previous work indicates that 1) adults with native sign language experience produce more manual co-speech gestures than monolingual non-signers, and 2) one year of ASL instruction increases gesture production in adults, but not enough to differentiate them from non-signers. To elucidate these effects, we asked early ASL–English bilinguals, fluent late second language (L2) signers (≥ 10 years of experience signing), and monolingual non-signers to retell a story depicted in cartoon clips to a monolingual partner. Early and L2 signers produced manual gestures at higher rates compared to non-signers, particularly iconic gestures, and used a greater variety of handshapes. These results …

American Sign Language Interpreters And Their Influence On The Hearing World, Madison Groat

Senior Honors Theses

This honors thesis is going to discuss the hearing community’s perception of American Sign Language and by association the hearing community’s perception of the Deaf community. For most of the hearing community their only interaction with American Sign Language is through watching an interpreter perform at their job. They personally have no physical interactions with the language. Even though they have never personally used the language or attempted to interact with the Deaf community they will draw their own conclusions about sign language and the Deaf community. The conclusions that are assumed tend to be incorrect. Early on in the …
