Co-speech gesture in monolinguals has been linked to several cognitive processes: prompting memory stores, conveying spatial concepts, searching for lexical equivalents, and supporting rhythm and cohesion. The production of co-speech gesture also occurs in spoken language bilinguals. Studies have demonstrated that bilinguals fluent in American…

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…

This study aimed to explore the literacy interactions of deaf and hearing parents with their preschool children in Saudi Arabia. The participants were three sets of parents (six individuals) of preschoolers. Data were collected through home literacy observation, experience sampling method, and interviews. All participants endorsed learning through…

Purpose: There are well-established guidelines for the recording, transcription, and analysis of spontaneous oral language samples by researchers, educators, and speech pathologists. In contrast, there is presently no consensus regarding methods for the written documentation of sign language samples. The Handshape Analysis Recording Tool (HART) is…

Past work investigating spatial cognition suggests better mental rotation abilities for those who are fluent in a signed language. However, no prior work has assessed whether fluency is needed to achieve this performance benefit or what it may look like on the neurobiological level. We conducted an electroencephalography experiment and assessed…

Despite different childhood experiences--primarily differences centered around language access--the authors share stories of growing up in large Spanish-speaking families with a strong sense of cultural identity and values. Now as they raise three children together, this is what they want for them as well--a sense of cultural identity and pride,…

Using a free-recall paradigm, we explored the effects of age of acquisition and category size on verbal fluency in Turkish Sign Language (Türk Isaret Dili [TID]). We studied the semantic and phonological fluency task performances of deaf native and deaf late adult signers. We measured the number of correct responses and performed a time course…

Purpose: This study aimed to examine how speech while sign (simultaneous communication [SimCom]) affects the spoken language of bimodal bilingual teachers and how individual differences in sign-language vocabulary knowledge, SimCom teaching experience, and the ability to perform speech under dual-task conditions explain the variability in SimCom…

The "unskilled and unaware effect" refers to the finding that individuals who are less knowledgeable or less skilled in a domain are relatively less able to evaluate their level of skill or effectively utilise feedback relative to individuals who are more skilled. Studies finding deaf students less accurate than hearing students in…

Successful face-to-face communication involves multiple channels, notably hand gestures in addition to speech for spoken language, and mouth patterns in addition to manual signs for sign language. In four experiments, we assess the extent to which comprehenders of British Sign Language (BSL) and English rely, respectively, on cues from the hands…

This study investigated the impact of language modality and age of acquisition on semantic fluency in American Sign Language (ASL) and English. Experiment 1 compared semantic fluency performance (e.g., name as many animals as possible in 1 min) for deaf native and early ASL signers and hearing monolingual English speakers. The results showed…

Families with deaf parents and hearing children often demonstrate bimodal bilingualism, using both a signed and a spoken language. This study uses an audience design framework to analyze the home language use of two bimodal bilingual families in the United States. The school-age children in these families appeared to design their utterances for…

The nature of this research study examines the relationship between text-talking and writing skills used by American Sign Language (ASL) and English speakers. When given ample opportunity to text-talk in academic settings, it is likely that students will improve their expressive communication and writing skills. The main research question asks:…

Background: Deafness has an adverse impact on children's ability to acquire spoken languages. Signed languages offer a more accessible input for deaf children, but because the vast majority are born to hearing parents who do not sign, their early exposure to sign language is limited. Deaf children as a whole are therefore at high risk of language…
