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…

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…

Signed languages continue to be a key element of deaf education programs that incorporate a bilingual approach to teaching and learning. In order to monitor the success of bilingual deaf education programs, and in particular to monitor the progress of children acquiring signed language, it is essential to develop an assessment tool of signed…

Deaf learners whose first language is American Sign Language face particular challenges and constraints in developing literacy in English as a second language. These constraints are interrogated and discussed in terms of their relationship to issues of language proficiency in both L1 and L2, and to models of second language literacy education.…

Examines the theoretical models and arguments in the debate concerning possible relationships between natural sign language proficiency and English literacy. It presents findings of a study with 155 school-aged deaf children that supported such a connection. (DB)

Critically examines the traditional notion of American Sign Language/English bilingualism. This model is contrasted with the "ASL/English as a spoken language" bilingual model in which the modality constraints facing the deaf child are presented as the fundamental issue for ASL/English bilingualism. Empirical and applied research supporting the…
