An analysis was made of the correspondence between intonation and the larger and smaller movements accompanying two-syllable and longer utterances. Synchrony between peaks of intonation and movement pattern was found and is used to argue for a performative basis for early two-word productions. (Author/EJS)

Examines whether early simultaneous bilingual language exposure causes children to be language delayed or confused. Cites research suggesting normal and parallel linguistic development occurs in each language in young children and young children's dual language developments are similar to monolingual language acquisition. Research on simultaneous…

Reports on research into the early semantic-syntactic utterances of deaf children as compared to those of learning children. It is suggested that differences in acquisition patterns may be attributable to the pedagogical nature of deaf language acquisition. (Author/AM)

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

Explores the process of language acquisition, including such aspects as pre-language, speaking and signing, and cultural influences, focusing on the resulting language acquisition differences and needs of children whose language ability and medium do not correspond with those of their family. (CB)

For the two children studied and in the situations observed and recorded, important conditions for the emergence of language in the ontogeny of communication appear to be: (1) interaction with caretaking adults, (2) shared focal attention, and (3) specificity of reference. (Author)

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)

Face-to-face communication makes up only a small proportion of an infant's diurnal transactions with his environment, but it is viewed as crucial to his total development. Research was conducted in which adult and infant behaviors were videotaped, and their interactions were analyzed. (Author/HP)

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…

Examines arguments that language comes from innate, abstract knowledge of universal grammar that signers use to create new grammatical features. (12 references) (CK)

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…

Reports on a study which followed the language development of a hearing son of deaf parents from his seventeenth month to twenty-third month. Various aspects of the child's language acquisition in sign and speech are described, as is his early ability to alternate languages (sign and speech) according to addressee. (SED)
