Investigates sign learning as a function of sign translucency (ease of relating a sign to its referents) and referential concreteness. Naive sign learners attempted to learn a list of sign-referent pairs. Signs high in translucency and referents high in concreteness facilitated learning; low levels of each variable inhibited learning. (Author/PJM)

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)

A study of spontaneous sign language of six deaf children of hearing parents, examined three times in a 15-month period, is described. Processes and structures representative of and not representative of signed English were sought at various levels of linguistic complexity, including developing semantics, and compared with American Sign Language.…

Studies the developmental stages deaf children pass through in acquiring the adult forms of pronominal classifiers in American Sign Language. Data were obtained on production, comprehension, and imitation from nine children aged 3 to 11. Complexities of classifier usage influence the learning strategies used. (PJM)

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.
