Universal Dependencies For Amahuaca, Candy Angulo, Pilar Valenzuela, Roberto Zariquiey
Universal Dependencies For Amahuaca, Candy Angulo, Pilar Valenzuela, Roberto Zariquiey
World Languages and Cultures Faculty Articles and Research
This paper presents the creation of a Universal Dependency (UD) treebank for Amahuaca (Peru), marking the first UD treebank within the Headwaters subbranch of the Panoan family, spoken mostly in Peru and Brazil. While the UD guidelines provided a general framework for our annotations, language-specific decisions were necessary due to the rich morphology of the Amahuaca language. The paper also describes specific constructions to initiate a discussion on several general UD annotation guidelines, particularly those concerning clitics and morpheme-level dependencies.

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 …
Improving Sign Recognition With Phonology, Lee Kezar, Jesse Thomason, Zed Sevcikova Sehyr
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 …
Language Classification In Western Amazonia: Advances In Favor Of The Pano-Takana Hypothesis, Pilar M. Valenzuela, Roberto Zariquiey
Language Classification In Western Amazonia: Advances In Favor Of The Pano-Takana Hypothesis, Pilar M. Valenzuela, Roberto Zariquiey
World Languages and Cultures Faculty Articles and Research
The languages of the Pano and Takana families exhibit a considerable number of lexical and structural affinities that cannot be ascribed to mere chance and are not readily detectable instances of borrowing. After the comparative studies by Key (1968) and Girard (1971) the proposal of a genetic relationship between these two families was generally accepted (e.g. Loos 1973, 2005; Suárez 1973; Kaufman 1990; Campbell 1997). Without solid argumentation, however, this classification was later put into question (Fabre 1998; Loos 1999; Fleck 2013) and, even today, there is no full consensus as to whether the observed similarities are due to genetic …
Degrees Of Temporal Remoteness In Pano: Contribution To The Cross-Linguistic Study Of Tense, Pilar Valenzuela, Sanderson Castro Soares De Oliveira
Degrees Of Temporal Remoteness In Pano: Contribution To The Cross-Linguistic Study Of Tense, Pilar Valenzuela, Sanderson Castro Soares De Oliveira
World Languages and Cultures Faculty Articles and Research
Beyond simply indicating future or past tense, the languages of the Pano family grammatically distinguish various degrees of temporal distance relative to a reference point, typically the moment of utterance; i.e., they possess what has been called ‘metrical tense’ (Chung & Timberlake 1985; Frawley 1992), ‘degrees of remoteness’ (Comrie 1985; Dahl 1985; Bybee et al. 1994; Botne 2012), or ‘graded tense’ (Cable 2013). This article offers a comparative analysis of the rich graded tense systems found in Pano, concentrating on morphologically expressed categories. In so doing, it seeks to expand our typological knowledge of languages exhibiting this feature, particularly …
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
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 …
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
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 …
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
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
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
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
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 …

Referring Strategies In American Sign Language And English (With Co-Speech Gesture): The Role Of Modality In Referring To Non-Nameable Objects, Zed Sevcikova Sehyr, Brenda Nicodemus, Jennifer Petrich, Karen Emmorey
Communication Sciences and Disorders Faculty Articles and Research
American Sign Language (ASL) and English differ in linguistic resources available to express visual–spatial information. In a referential communication task, we examined the effect of language modality on the creation and mutual acceptance of reference to non-nameable figures. In both languages, description times reduced over iterations and references to the figures’ geometric properties (“shape-based reference”) declined over time in favor of expressions describing the figures’ resemblance to nameable objects (“analogy-based reference”). ASL signers maintained a preference for shape-based reference until the final (sixth) round, while English speakers transitioned toward analogy-based reference by Round 3. Analogy-based references were more time efficient …

The temporo-occipitally distributed N170 ERP component is hypothesized to reflect print-tuning in skilled readers. This study investigated whether skilled deaf and hearing readers (matched on reading ability, but not phonological awareness) exhibit similar N170 patterns, given their distinct experiences learning to read. Thirty-two deaf and 32 hearing adults viewed words and symbol strings in a familiarity judgment task. In the N170 epoch (120–240 ms) hearing readers produced greater negativity for words than symbols at left hemisphere (LH) temporo-parietal and occipital sites, while deaf readers only showed this asymmetry at occipital sites. Linear mixed effects regression was used to examine the …

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 …
Different Neural Mechanisms For Causal Processing In Language And Perception: An Fmri Study, Brett B. Bankson, Dirk B. Den Ouden
Different Neural Mechanisms For Causal Processing In Language And Perception: An Fmri Study, Brett B. Bankson, Dirk B. Den Ouden
Communication Sciences and Disorders Faculty Articles and Research
Information that is used to establish and evaluate causal relationships between objects and events can be gleaned from many sources, especially those that rely on language and perception. For example, sentences with a verb structure using change of state verbs such as “to break” or “to freeze” imply sequential events that express understood causal relationships. At this time, little research has examined the neural correlates of causal verb processing or has compared them to the more well researched brain activity involved in perceptual causal processing. This study investigated the extent to which the evaluation of causal verbs and causal image …
Predicate Structures, Gesture, And Simultaneity In The Representation Of Action In British Sign Language: Evidence From Deaf Children And Adults, Kearsy Cormier, Sandra Smith, Zed Sehyr
Predicate Structures, Gesture, And Simultaneity In The Representation Of Action In British Sign Language: Evidence From Deaf Children And Adults, Kearsy Cormier, Sandra Smith, Zed Sehyr
Communication Sciences and Disorders Faculty Articles and Research
British Sign Language (BSL) signers use a variety of structures, such as constructed action (CA), depicting constructions (DCs), or lexical verbs, to represent action and other verbal meanings. This study examines the use of these verbal predicate structures and their gestural counterparts, both separately and simultaneously, in narratives by deaf children with various levels of exposure to BSL (ages 5;1 to 7;5) and deaf adult native BSL signers. Results reveal that all groups used the same types of predicative structures, including children with minimal BSL exposure. However, adults used CA, DCs, and/or lexical signs simultaneously more frequently than children. These …

Shiwilu (Jebero), Pilar Valenzuela, Carlos Gussenhoven
World Languages and Cultures Faculty Articles and Research
Shiwilu (a.k.a. Jebero) is a critically endangered language from Peruvian Amazonia and one of the two members of the Kawapanan linguistic family. Most of its nearly 30 remaining fluent speakers live in and around the village of Jeberos (District of Jeberos, Province of Alto Amazonas, Loreto Region), at approximately 5° S, 75° W. The documentation of Shiwilu is scarce and no survey grammar is available. Until very recently, the only trained linguist who had worked on Shiwilu was John Bendor- Samuel, who carried out fieldwork in 1955–1956 and completed a doctoral thesis in 1958 (see Bendor-Samuel 1981 [1958]). An abridged …
Lexicalization And De-Lexicalization Processes In Sign Languages: Comparing Depicting Constructions And Viewpoint Gestures, Kearsy Cormier, David Quinto-Pozos, Zed Sehyr, Adam Schembri
Lexicalization And De-Lexicalization Processes In Sign Languages: Comparing Depicting Constructions And Viewpoint Gestures, Kearsy Cormier, David Quinto-Pozos, Zed Sehyr, Adam Schembri
Communication Sciences and Disorders Faculty Articles and Research
In this paper, we compare so-called “classifier” constructions in signed languages (which we refer to as “depicting constructions”) with comparable iconic gestures produced by non-signers. We show clear correspondences between entity constructions and observer viewpoint gestures on the one hand, and handling constructions and character viewpoint gestures on the other. Such correspondences help account for both lexicalisation and de-lexicalisation processes in signed languages and how these processes are influenced by viewpoint. Understanding these processes is crucial when coding and annotating natural sign language data.
Argument Encoding And Pragmatic Marking Of The Transitive Subject In Shiwilu (Kawapanan), Pilar Valenzuela
Argument Encoding And Pragmatic Marking Of The Transitive Subject In Shiwilu (Kawapanan), Pilar Valenzuela
World Languages and Cultures Faculty Articles and Research
Shiwilu (a.k.a. Jebero) is a nearly extinct Kawapanan language from Peruvian Amazonia. The goal of this article is twofold. First, it investigates the obligatory cross-referencing of arguments in the complex Shiwilu verb. This system is predominantly nominative accusative, with the caveat that main clause object markers coincide with those conveying subject in one type of clause involving nominal predicates, as well as subject and object of dependent clauses. Second, this article provides a first analysis of the enclitic =ler, which may attach to transitive subjects and thus exhibits an ergative-like distribution. Unlike the situation in languages with syntacticized ergative systems, …
Applicative Constructions In Shipibo-Konibo (Panoan), Pilar Valenzuela
Applicative Constructions In Shipibo-Konibo (Panoan), Pilar Valenzuela
World Languages and Cultures Faculty Articles and Research
This article provides a detailed, typologically informed treatment of applicative constructions in Shipibo-Konibo, a Panoan language from Peruvian Amazonia. Shipibo-Konibo has three applicative suffixes: affective (i.e., benefactive or malefactive), dedicated malefactive, and associative. These applicative types are rather common cross-linguistically and hence the language cannot be said to be particularly rich either in terms of number or kinds of applicative constructions. Nevertheless, the Shipibo-Konibo system exhibits certain points of special interest such as the interplay between transitivity and the different applicative construction types, which include a restriction on the dedicated malefactive to combine with transitive verbs only, and the almost …
The Electrophysiological Manifestation Of Dutch Verb Second Violations, Dirk B. Den Ouden, Roelien Bastiaanse
The Electrophysiological Manifestation Of Dutch Verb Second Violations, Dirk B. Den Ouden, Roelien Bastiaanse
Communication Sciences and Disorders Faculty Articles and Research
We investigated the processing of violations of the verb position in Dutch, in a group of healthy subjects, by measuring event-related potentials (ERPs) through electroencephalography (EEG). In Dutch, the base position of the verb is clause final, but in matrix clauses, the finite verb is in second position, a construction known as Verb Second. In embedded clauses, the finite verb remains in its clause-final base position. The results show that ungrammatical placement of finite verbs in second position in embedded clauses yields a P600 response, which suggests that the parser treats this type of violation as a clear syntactic …
