Infants are born highly sensitive to the natural patterns found in languages. They use their perceptual sensitivity to acquire detailed information about the structure of languages in their environment. To date, most studies of infant perception and early language acquisition have investigated spoken/auditory languages and hearing infants (e.g.…

The visual-manual modality of sign languages renders them a unique test case for language acquisition and processing theories. In this commentary the authors describe evidence from signed languages, and ask whether it is consistent with Ambridge's proposal. The evidence includes recent research on collocations in American Sign Language that reveal…

Explores the predictors of early mastery versus error in children's acquisition of American Sign Language. Hypothesizes that the most frequent values for a particular parameter in prelinguistic gesture will be the most frequent in early signs and the most likely sources of substitution when children make errors.

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

The acquisition of several word formation devices in American Sign Language (ASL) by deaf children learning ASL as a native language focused on some devices analogous to word formation devices in spoken languages (compounding, affixation, and derivation) and some in ASL that may not have counterparts in spoken languages. They were examined using…

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)

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…

A collection of papers addresses a variety of issues regarding the nature and structure of sign language, gesture, and gesture systems. Articles include: "Theoretical Issues Relating Language, Gesture, and Space: An Overview" (Karen Emmorey, Judy S. Reilly); "Real, Surrogate, and Token Space: Grammatical Consequences in ASL American…
