Most deaf children have hearing parents who do not know a sign language at birth and are at risk of limited language input during early childhood. Studying these children as they learn a sign language has revealed that timing of first-language exposure critically shapes language outcomes. But the input deaf children receive in their first language…

Deaf children of hearing parents (DOH) are at risk for early language delays (ELD) due to environmental and etiological factors, compounding the previously reported higher incidence of ELD in deaf children of deaf parents (DOD) compared to the general population. Archival data from the online database of the Visual Communication and Sign Language…

Lexical iconicity--signs or words that resemble their meaning--is overrepresented in children's early vocabularies. Embodied theories of language acquisition predict that symbols are more learnable when they are grounded in a child's firsthand experiences. As such, pantomimic iconic signs, which use the signer's body to represent a body, might be…

When children interpret spoken language in real time, linguistic information drives rapid shifts in visual attention to objects in the visual world. This language-vision interaction can provide insights into children's developing efficiency in language comprehension. But how does language influence visual attention when the linguistic signal and…

Across a diverse range of languages, children proceed through similar stages in their production of causal language: their initial verbs lack internal causal structure, followed by a period during which they produce causative overgeneralizations, indicating knowledge of a productive causative rule. We asked in this study whether a child not…

Introduction: Baby sign language is gaining in popularity. However, research has indicated a lack of empirical research supporting its use. In addition, research suggests that baby sign training may increase stress levels in parents. Methods: Nine families with children ranging in age from six months to two years; five months participated in a…

This article argues for the necessity of phonetic analysis in signed language linguistics and presents a case study of one analytical system being used in a preliminary attempt to identify natural classes and investigate variation in ASL handshapes. Robbin Battison (1978) first described what is now a widely accepted list of basic handshapes,…

Mounting evidence points to joint attention as a mediating variable in children's adaptive behavior. Joint attention in interactions between hearing mothers and congenitally deaf (n = 27) and hearing (n = 29) children, ages 18-36 months, was examined. All deaf children had severe to profound hearing loss. Mother-child interactions were coded for…

This study examined young children's hand usage when they produced American Sign Language signs and while they played, in order to determine their hand preference in early signing and to compare their hand use in signing with their hand preference in other, nonlinguistic, motor actions. Subjects were 24 young children (from the age of 12 months or…

This article discusses the development of the MacArthur Communicative Development Inventory for American Sign Language (ASL-CDI), a parent report that measures early sign production. Normative data from 69 children (8-36 months) with deafness and their parents with deafness found the development of the ASL-CDI has been successful. (Contains…

Hand preference during signing was examined longitudinally in nine very young children with deaf parents. These children generally showed a distinct and persistent hand preference in their signing, beginning with the production of their first signs. (14 references) (VWL)

The acquisition of the formational aspects of American Sign Language signs was examined in nine young children of deaf parents. Videotape records of early sign language development were made during monthly home visits. The study focused on the acquisition of three principal formational components of any American Sign Language sign: location,…

A longitudinal study investigated how a hearing child of deaf parents simultaneously acquired American Sign Language and spoken English. Neither of two unique properties of signed language (personal pronouns or "negative" sign markers) facilitated acquisition of English, suggesting that children's acquisition of grammar is relatively…

Acquisition of the location aspect of American Sign Language signs was examined in nine young hearing infants and toddlers of deaf parents. Sign locations, overall, were produced with 83.5% accuracy. Highly contrasting locations were acquired first. Location played a central role in young children's early sign language acquisition. (Author/DB)

Describes the Deaf Mentor Experimental Project, which provided deaf-mentor services to young deaf children, ages 0 to 5, and their families. Deaf adults (mentors) shared their language (American Sign Language), culture, and personal knowledge of deafness while serving as role models for the children. Program children made greater language gains…
