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…

In my dissertation, I examine four notation systems used to represent hand configurations in child acquisition of signed languages. Linguists have long recognized the descriptive limitations of Stokoe notation, currently the most commonly used system for phonetic or phonological transcription, but continue using it because of its widespread…

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…

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…

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)

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…

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…

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)

A study investigated acquisition of three independent yet simulatneously produced morphological systems in American Sign Language (ASL): the linguistic use of space, use of classifiers, and inflections for aspect, all information incorporated into the production of a sign. Subjects were 30 deaf children with severe or profound prelingual hearing…

A study was conducted of the language development of a hearing child whose mother was deaf and communicated only in sign and whose father was hearing and communicated in both sign and oral language. Results showed similarities in development between the two modalities as well as similarity between development in two separate modalities and two…

Examines the effect of adult recasting in sign language on the acquisition of specific syntactic-semantic structures by deaf children aged 9 to 76 months. Results indicated that recasting triggered the acquisition of new syntactic-semantic structures in American Sign Language and English, evident in the spontaneous production of previously…

Gaze during utterance was examined in a set of bilingual-bimodal twins acquiring spoken English and American Sign Language (ASL) and a set of monolingual twins acquiring ASL. The bilingual-bimodal twins differentiated their languages by age 3. Like the monolingual twins, the bilingual-bimodal twins established mutual gaze at the beginning of their…
