Linguistic expressions of locative spatial relations in sign languages are mostly visually motivated representations of space involving mapping of entities and spatial relations between them onto the hands and the signing space. These are also morphologically complex forms. It is debated whether modality-specific aspects of spatial expressions…

Previous studies suggest that age of acquisition affects the outcomes of learning, especially at the morphosyntactic level. Unknown is how syntactic development is affected by increased cognitive maturity and delayed language onset. The current paper studied the early syntactic development of adolescent first language learners by examining word…

Languages typically express semantic components of motion events such as manner (roll) and path (down) in separate lexical items. We explore how these combinatorial possibilities of language arise by focusing on (i) gestures produced by deaf children who lack access to input from a conventional language (homesign); (ii) gestures produced by…

There is debate about how input variation influences child language. Most deaf children are exposed to a sign language from their non-fluent hearing parents and experience a delay in exposure to accessible language. A small number of children receive language input from their deaf parents who are fluent signers. Thus it is possible to document the…

Children typically acquire their native language naturally and spontaneously at a very young age. The emergence of early grammar can be predicted from children's vocabulary size and composition (Bates et al., 1994; Bates, Bretherton & Snyder, 1998; Bates & Goodman, 1997). One central question in language research is understanding what…

We investigated whether access to a sign language affects the development of pragmatic competence in three groups of deaf children aged 6 to 11 years: native signers from deaf families receiving bimodal/bilingual instruction, native signers from deaf families receiving oralist instruction and late signers from hearing families receiving oralist…

This study explores the form of representational gestures produced by forty-five hearing children (age range 2 ; 0-3 ; 1) asked to label pictures in words. Five pictures depicting objects and five pictures depicting actions which elicited more representational gestures were chosen for more detailed analysis. The range of gestures produced for each…

Spontaneous gestures of a deaf child unexposed to sign language were studied to determine whether regularities existing within gestures were akin to morphological structure. The child's gestures, handshape/motion combinations forming a matrix for communication, suggest that structural regularity at the intraword level is a resilient property of…

Considers the cross-linguistic findings concerning the early development of formal, arbitrary, grammatical systems in normal hearing and deaf children and in children with congenital brain abnormalities. Evidence is reviewed that shows an early acquisition of grammatical forms. (Author/JL)

Research is reported which investigated the ability of four-month-old hearing infants to discriminate between gestures derived from American Sign Language. Findings show that infants possess the perceptual abilities to differentiate between signs that differ solely in terms of contrasts along a single underlying movement direction. (SED)

Studied the case of bilingual acquisition across two modalities to examine diverging hypotheses about the types of knowledge underlying early bilingualism. Three children acquiring Langues des Signes Quebecoise and French, and three children acquiring French and English were videotaped over a year while novel and familiar speakers of each child's…

Gaze during utterance was examined in a set of bilingual-bimodal twins acquiring spoken English and American Sign Language (ASL) and a set of monolingual twins acquiring ASL. The bilingual-bimodal twins differentiated their languages by age 3. Like the monolingual twins, the bilingual-bimodal twins established mutual gaze at the beginning of their…
