Some studies have concluded that sign language hinders spoken language development for deaf and hard-of-hearing (DHH) children even though sign language exposure could protect DHH children from experiencing language deprivation. Furthermore, this research has rarely considered the bilingualism of children learning a signed and a spoken language.…

Purpose: Deaf children are frequently reported to be at risk for difficulties in executive function (EF); however, the literature is divided over whether these difficulties are the result of deafness itself or of delays/deficits in language that often co-occur with deafness. The purpose of this study is to discriminate these hypotheses by…

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…

Child development researchers often discuss a "two-word" stage during language acquisition. However, there is still debate over whether the existence of this stage reflects primarily cognitive or linguistic constraints. Analyses of longitudinal data from two Deaf children, Mei and Cal, not exposed to an accessible first language (American Sign…

Argues that WH-Movement in American Sign Language (ASL) is a leftward specifier of CP. Also argues that the occurrence of rightward WH-elements derives from independently motivated syntactic and discourse factors leading to the appearance of WH-elements in a sentence- or discourse-final positions--not by rightward WH-movement. This analysis…

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…

In an examination of the acquisition of the spatial syntax of American Sign Language (ASL), 43 children aged 3-10 years were given a range of comprehension and elicitation tests designed to analyze the subsystems involved in the corrrect use of ASL syntax. The subsystems were nominal establishment, verb agreement, and consistency of reference. The…

Presents two probe recognition experiments investigating whether overt and null pronouns in American Sign Language (ASL) similarly reactivate their referents during online sentence comprehension. Both experiments indicated that an important link exists between spatial verb agreement and the ASL pronomial system and that nonreferent inhibition does…

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…
