Across languages, children map words to meaning with great efficiency, despite a seemingly unconstrained space of potential mappings. The literature on how children do this is primarily limited to spoken language. This leaves a gap in our understanding of sign language acquisition, because several of the hypothesized mechanisms that children use…

This article reports the results of the first longitudinal study that systematically investigates the acquisition of verb agreement by hearing learners of a sign language. During a 2-year period, 14 novel learners of Sign Language of the Netherlands (NGT) with a spoken language background performed an elicitation task 15 times. Seven deaf native…

Following a year of study of Saudi Arabian Sign Language (SASL), we are documenting our findings to provide a grammatical sketch of the language. This paper represents one part of that endeavor and focuses on a description of selected morphemes, both manual and non-manual, that have appeared in the course of data collection. While some of the…

Background: Specific language impairment has previously solely been documented for children acquiring spoken languages, despite informal reports of deaf children with possible sign language disorder. The paper reports the case of a deaf child exposed to British Sign Language (BSL) from birth, who has significant developmental deficits in the…

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…

A study examined the process of grammaticalization in American Sign Language, examining basic principles and patterns and drawing parallels with oral language. More advanced stages of grammaticalization (involving fusion and affecting syntax) are examined in depth, leading to proposal of a temporal-ordering analysis to explain sequencing of verbal…

Investigates the differences in the use of certain verbs of movement and location between native ASL learners and children of hearing parents exposed to signing outside the home. Describes the children's use of phonology, morphology, and syntax in repeating target utterances. Relates results to interaction of language acquisition and motor…

Papers presented at a 1977 symposium on language acquisition held at the University of Wisconsin/Milwaukee are included. Contents are as follows: "Assumptions, Methods and Goals in Language Acquisition Research" (Sheldon); "The Mother as LAD: Interaction between Order and Frequency of Parental Input and Child Production"…
