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…

Discoveries about the acquisition of American Sign Language (ASL) by deaf children are reviewed. Current research shows that ASL has developed as a fully autonomous language with complex organizational properties not derived from spoken language. Like spoken languages, ASL exhibits formal structuring at two levels and similar organizational…

Examines why bilingual education for deaf children is the best option, suggesting ways to ensure that deaf students receive the necessary American Sign Language (ASL) models in their early education. Notes that the best way to achieve success in ASL, and consequently in English, is to require that preschool teachers of deaf students be native…

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)

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

Reviews work on the acquisition of complex verbs in American Sign Language (ASL), delineating three lines of research showing how children acquire ASL and discussing possible reasons for the particular fashion in which different children (native learners, non-native learners, and native learners with parents who are non-native learners) acquire…

In examining the issue of why children do so well at language learning despite limited skill and experience, two possible explanations are addressed: one suggests that children learn language well exactly because they are limited, and the other proposes that children are extremely adept at language learning, perhaps more so than adults. Research…

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)

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)

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)

Argues against the linguistic account of children's responses to sentences with universal quantification and reports on investigations of their comprehension and production of quantificational sentences. The article concludes that young children have full grammatical competence with universal quantification. (58 references) (Author/CK)

Examination of the spoken English development of a hearing child whose deaf parents used American Sign Language (ASL) identified a consistent but not extensive ASL influence on simultaneity of expression, undifferentiated versus differentiated features, bound versus free morpheme mechanisms, and word order. (47 references) (Author/CB)

Examines the relationship between sign language and gesture in language acquisition. Specifically, the question is asked, are sign language and nonlinguistic gestures treated differently by infants acquiring a sign language? The answer is found in reexamining data concerning two deaf children learning American Sign Language (ASL). The data…

This research focused on the initial stage of language development of a hearing child who was acquiring simultaneously both spoken English and American Sign Language (ASL). The report covers the first phase of the longitudinal research on the child's linguistic development, focusing on early word meanings. The data were collected from the time…

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.
