Discusses the modifications in the direction of simplified and more linear language (American Sign Language) used by deaf mothers with their deaf children. (EKN)

Examination of American Sign Language--produced by a deaf child acquiring the language from deaf parents, and videotaped at age 13, 15, 18, and 21 months--shows conformity to many of the phonological rules operative for all languages. (Author/CFM)

Reports research on the communicative behavior of a hearing child whose parents communicated with him, from birth, in both signs and words. The child's expressive ability accelerated in both modalities and this is possibly attributable to the addition of the signed component. (PJM)

Replication of a study that showed that deaf 15- to 18-year- olds could accurately identify a significant number of isolated signs presented well out in peripheral vision found that 8- to 12-year-olds could also identify such signs, although results showed a significant effect of age on performance.

Studies the simultaneous language development in American Sign Language and spoken English by a hearing girl. Findings show: (1) a mixture of oral and manual babbling, (2) a code-switching ability across modalities, and (3) a single syntactic system incorporating rules from both languages but with two separate lexicons. (Author/PJM)

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…

Explores the acquisition of productive verbs and (spatial) agreement of American Sign Language (ASL) in the signing of two deaf children with hearing parents. The children, observed at two ages, initially showed markedly different developmental trends. Then their grammatical development converged, and they were able to suit ASL to the kind of…

Longitudinal study of a deaf child's (with deaf signing and speaking parents) speech functions revealed that the child, before age three, rarely attempted speech imitation. By age five, the child had acquired new words through speechreading and had adjusted language modes to listener needs for flexible communication, and speech behavior assumed…

Describes code shifting study in communicative behavior of hearing child interacting with deaf child and mother, both of whom signed. Hearing child knew signing, but did not sign at home. Although communication change occurred, code shifting was influenced more by motivational variables and by hearing child's own flexibility with language than by…

Reports on an experiment describing the lexical development of a hearing child with a deaf mother and hearing father. Data confirm previous findings that (1) sign emerges before spoken word, (2) acquisition stages are similar in ASL and spoken English, and (3) the child initially develops one lexical system. (Author/AM)

Some 76 hearing children in prekindergarten classes, half receiving sign instruction and half not, were tested on English vocabulary acquisition. Children who received the sign instruction scored significantly higher on the Peabody Picture Vocabulary Test than children receiving sign instruction. (Contains 15 references.) (Author/LB)

Observation of severely to profoundly deaf four- to nine-year-olds (N=24) producing three types of multi-morphemic classifier predicates in American Sign Language showed that handshape production was influenced both by morphological and syntactic complexity, while handshape errors were not based on anatomical complexity alone. (26 references)…

A young child's acquisition of language and language-related skills in two modalities is discussed. The hearing daughter of a deaf father and of a hearing mother showed accelerated language development in both sign and speech. Reading readiness tests administered at 27 and 32 months revealed advanced development for her age. (Author/LMO)
