Children's ability to share attention with another social partner (joint attention) plays an important role in language development. However, our understanding of the role of joint attention comes mainly from children learning spoken languages, which gives a very narrow, speech-centric impression of the role of joint attention. This study broadens…

Martha's Vineyard Sign Language (MVSL) is an extinct village sign language hypothesized to be a sister of British Sign Language (BSL) and a significant contributor to early American Sign Language (ASL) (Groce 1985). After the last deaf MVSL signer died, signs were elicited from five hearing signers. This study analyzes that data through a series…

Visual manifestations of an object that moves from one place to another are common in sign languages. Here, we offer an overview of techniques for conveying motion of an entity based on an examination of storytelling and poetry in seven sign languages. The signer can use embodiment and/or classifiers to show translocating movement of an object, or…

Multiple-baseline-across-word-sets designs were used to determine whether a computer-based intervention would enhance accurate word signing with four participants. Each participant was a hearing college student with reading disorders. Learning trials included 3 s to observe printed words on the screen and a video model performing the sign twice…

In this study, 19 college-educated deaf adults with experience using interpreters in educational settings provided insights into how successfully various elements of classroom discourse were preserved through interpretation. The deaf adults, fluent in American Sign Language (ASL) and experienced at using interpreters, watched educational…

Much like early speech, early signing is characterised by modifications. Sign language phonology has been analysed on the feature level since the 1980s, yet acquisition studies predominately examine handshape, location, and movement. This study is the first to analyse the acquisition of phonology in the sign language of a Balinese village with a…

For some deaf people, sign language is the preferred language, the one in which they feel most comfortable. However, there are very few assessment tools developed or adapted for sign languages. The aim of this study was to translate and adapt in Italian Sign Language (LIS) the Italian version of the Youth Quality of Life Instrument--Deaf and Hard…

The aim of this research was to analyze the use of iconicity during language acquisition of Israeli Sign language and spoken Hebrew. Two bilingual-bimodal infants were observed in a longitudinal study between the ages of 10-26 months. I analyzed infants' production of iconic words, signs, and gestures. The results showed that infants' use of vocal…

Studies have shown that iconicity can provide a benefit to non-signers during the learning of single signs, but other aspects of signed messages that might also be beneficial have received less attention. In particular, do other features of signed languages help support comprehension of a message during the process of language learning? The…

Variation occurs in sign languages, just as in spoken languages. Lexical variation is very common and has been related to individual schools for the deaf, so-called "schoolization," rather than only to region or other common sociolinguistic factors, such as gender, social class, etc. (Baker et al. 2016). This study investigates lexical…

Expressing Left-Right relations is challenging for speaking-children. Yet, this challenge was absent for signing-children, possibly due to iconicity in the visual-spatial modality of expression. We investigate whether there is also a modality advantage when speaking-children's co-speech gestures are considered. Eight-year-old child and adult…

Signs in sign languages have been mainly analyzed as composed of three formational elements: hand configuration, location, and movement. Researchers compare and contrast lexical differences and similarities among different signs and languages based on these formal elements. Such measurement requires extensive manual annotation of each feature…

Although research of bilingualism in a single aural-oral linguistic mode is common, this has yet to be extended to visual-gestural modes of language use. This is a significant research gap, as deaf people and signed languages are agentic forces that contribute to a diverse global linguistic and sociocultural landscape. In this article, we present…

While deaf children learning American Sign Language (ASL) from deaf caregivers generally develop along typical trajectories, some have been skeptical that deaf children who have hearing caregivers--the majority of deaf children--can similarly benefit from ASL exposure. This study tracked ASL fluency and academic achievement among a large sample of…

Numbers and letters are culturally created symbols that acquire meaning through extensive training, significantly influencing brain function. The distinct hemispheric specialization of cortical regions for these categories has been hypothesized to relate to the co-activated brain networks: the left language regions for letters, and the right…
