In simultaneous interpreting studies, the concept of interference -- namely, the marks of the source language in the target language -- is perceived as a negative phenomenon. However, interference is likely to happen at a lexical level when the target language does not have its own lexicon. This is the case in international sign (IS), which can be…

The quality of sign language interpreting (SLI) is a gripping construct among practitioners, educators and researchers, calling for reliable and valid assessment. There has been a diverse array of methods in the extant literature to measure SLI quality, ranging from traditional error analysis to recent rubric scoring. In this study, we want to…

Facial expressions in sign language carry a variety of communicative features. While emotion can modulate a spoken utterance through changes in intonation, duration and intensity, in sign language specific facial expressions presented concurrently with a manual sign perform this function. When deaf adult signers cannot see facial features, their…

Children with autism spectrum disorder present with a variety of social communication deficits such as atypicalities in social gaze and verbal and non-verbal communication delays as well as perceptuo-motor deficits like motor incoordination and dyspraxia. In this study, we had the unique opportunity to study praxis performance in deaf children…

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…

This study investigated visual statistical learning (VSL) in 24 deaf signers and 24 hearing non-signers. Previous research with hearing individuals suggests that SL mechanisms support literacy. Our first goal was to assess whether VSL was associated with reading ability in deaf individuals, and whether this relation was sustained by a link between…

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…

Sensory systems are essential for perceiving and conceptualizing our semantic knowledge about the world and the way we interact with it. Despite studies reporting neural changes to compensate for the absence of a given sensory modality, studies focusing on the assessment of semantic processing reveal poor performances by deaf individuals when…

Students acquiring American Sign Language (ASL) as a second language (L2) struggle with fingerspelling comprehension more than skilled signers. These L2 learners might be attempting to perceive and comprehend fingerspelling in a way that is different from native signers, which could negatively impact their ability to comprehend fingerspelling.…

Effective literacy education in deaf students calls for psycholinguistic research revealing the cognitive and neural mechanisms underlying their written language processing. When learning a written language, deaf students are often instructed to sign out printed text. The present fMRI study was intended to reveal the neural substrates associated…

To identify neural regions that automatically respond to linguistically structured, but meaningless manual gestures, 14 deaf native users of American Sign Language (ASL) and 14 hearing non-signers passively viewed pseudosigns (possible but non-existent ASL signs) and non-iconic ASL signs, in addition to a fixation baseline. For the contrast…

The linguistic and cognitive profiles of five deaf adults with a sign language disorder were compared with those of matched deaf controls. The test involved a battery of sign language tests, a signed narrative discourse task and a neuropsychological test protocol administered in sign language. Spatial syntax and facial processing were examined in…

Bilinguals who are fluent in American Sign Language (ASL) and English often produce "code-blends"--simultaneously articulating a sign and a word while conversing with other ASL-English bilinguals. To investigate the cognitive mechanisms underlying code-blend processing, we compared picture-naming times (Experiment 1) and semantic categorization…

A review of "Sign Languages Used by Deaf People, and Psycholinguistics: A Critical Evaluation" (A. Van Uden, 1986), a book "denying that ...there is any such thing as a sign language," points out that a sign language's perceived lack of phonological and morphological rules is a more social than linguistic problem.

A collection of research materials on sign language and primatology is presented here. The essays attempt to show that: sign language is a legitimate language that can be learned not only by humans but by nonhuman primates as well, and nonhuman primates have the capability to acquire a human language using a different mode. The following…
