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…

Because sign languages have two main articulators, signers simultaneously experience both possibilities and constraints in the articulation and perception of linguistic messages. Sign languages commonly convey different linguistic units with each hand, and additional information is conveyed in nonmanual signals. Meaningful perseverations (or sign…

Research interest in heritage speakers and their patterns of bilingual development has grown substantially over the last decade, prompting sign language researchers to consider how the concepts of heritage language and heritage speakers apply in the Deaf community. This overview builds on previous proposals that ASL [American Sign Language] and…

American Sign Language verbs have several ways to indicate time: 1)reference to a specific time; 2) extension at wrist, elbow, or shoulder to indicate future time; 3) flexion at wrist, elbow, or shoulder to indicate past tense. (Author/LMO)

Replies to issues raised by Bouchard and Dubuisson (B&D) (1995) about American Sign Language (ASL), refuting B&D's assertion that visual-gestural languages are not bound by any universal constraints on word order and reaffirming that ASL is a highly configurational language with a basic underlying syntactic structure as well as an…

Briefly describes a program that sought to improve the written English skills of deaf adolescents' whose first language was American Sign Language, focusing on first-language skills, metalinguistic skills, translating skills, lexical matching across languages, translation of syntactical structures, and recognition of the importance of the…

This final report describes an effective, computer-based method of communicating new syntactic knowledge to students with deafness. "Choosing AVMs," the first intervention developed on the Macintosh computer, used advanced visual markers (AVMs) (icons) to communicate the essence of the syntactical structure to be taught by: (1) capturing…
