Children learning language efficiently process single words and activate semantic, phonological, and other features of words during recognition. We investigated lexical recognition in deaf children acquiring American Sign Language (ASL) to determine how perceiving language in the visual-spatial modality affects lexical recognition. Twenty native…

Late exposure to the first language, as in the case of deaf children with hearing parents, hinders the production of linguistic expressions, even in adulthood. Less is known about the development of language soon after language exposure and if late exposure hinders all domains of language in children and adults. We compared late signing adults and…

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…

Does spatial language influence how people think about space? To address this question, we observed children who did not know a conventional language, and tested their performance on nonlinguistic spatial tasks. We studied deaf children living in Istanbul whose hearing losses prevented them from acquiring speech and whose hearing parents had not…

The view that a deaf child with autism is just that--a deaf child first (because of the critical importance of communication) and an autistic child second--is the more prevalent today, especially in larger educational programs. But this was not always the case. In the past, placement decisions often were determined in the opposite way: Many deaf…

In the course of language development children must solve arbitrary form-to-meaning mappings, in which semantic components are encoded onto linguistic labels. Because sign languages describe motion and location of entities through iconic movements and placement of the hands in space, child signers may find spatial semantics-to-language mapping…

This study investigated whether deafness contributes to enhancement of visual spatial cognition, independent of knowledge of sign language. Comparison of 12 congenitally deaf children not exposed to sign language and 12 matched hearing controls found that the groups did not differ in their performance on visual spatial skills tests.

Reports on a study that investigated the perception in deaf children, aged 6 to 10, of American Sign Language signs that differ in only one major parameter to determine whether any of the three parameters (handshape, movement, and location) is more difficult than others for deaf children to discriminate. (SED)

In an examination of the acquisition of the spatial syntax of American Sign Language (ASL), 43 children aged 3-10 years were given a range of comprehension and elicitation tests designed to analyze the subsystems involved in the corrrect use of ASL syntax. The subsystems were nominal establishment, verb agreement, and consistency of reference. The…

This report, arising from a 1991 meeting, provides an update to two of the six areas covered in the 1989 long-term plan of the National Institute on Deafness and Other Communication Disorders. These include: (1) balance and the vestibular system; and (2) language and language impairments. For each area, the state of the art is reviewed, recent…

A study examined aspects of the acquisition of spatialized morphology and syntax in American Sign Language (ASL) learned natively by deaf children of deaf parents. Children aged 2 to 8 were shown story books to elicit narratives, and the resulting use of verbs contained morphological forms not appearing in adult grammar. Analysis of the creative…
