TLDR
It is concluded that, as in the hearing population, discourse functions involve the right hemisphere; that distinct discourse functions can be dissociated from one another in ASL; and that brain organization for linguistic spatial devices is driven by its functional role in language processing, rather than by its surface, spatial characteristics.About:

Figures
FIG. 8. Samples of AR and SJ’s drawings and block designs, showing deficits in spatial processing in both RHD deaf subjects. 
FIG. 6. Contrasting types of discourse errors in the two RHD deaf signers: Tangential utterances are very frequent in AR (60% of utterances) but essentially absent in SJ (left) and spatial errors in ASL discourse mechanisms are minimal in AR but rampant in SJ (right). 
FIG. 1. Linguistic contrasts in ASL involving crucial use of space at the lexical level, the morphological level, and the syntactic level. 
FIG. 5. Sample pictures from ‘‘Paint Story,’’ a wordless picture sequence designed to elicit spatialized discourse mechanisms of ASL.

The signing brain: the neurobiology of sign language
TL;DR: The authors found that the neural systems supporting signed and spoken languages are very similar: both involve a predominantly left-lateralised perisylvian network. But they also highlighted processing differences between languages in these different modalities.
Journal ArticleDOI
A critical period for right hemisphere recruitment in American Sign Language processing.
TL;DR: It is demonstrated that the RH angular gyrus is active during ASL processing only in native signers (hearing, ASL-English bilinguals) but not in those who acquired ASL after puberty ( hearing, native English speakers).
Journal ArticleDOI
The neural organization of discourse: an H2 15O-PET study of narrative production in English and American sign language.
TL;DR: Results indicate that anterior and posterior areas may play distinct roles in early and late stages of language production, and suggest a novel model for lateralization of cerebral activity during the generation of discourse.

Child Language: Acquisition And Growth
TL;DR: This chapter focuses on the development of an integrated theory of language acquisition through the acquisition of phonology, syntax, semantics and semantics in the context of a young child.

Journal ArticleDOI
The neurobiology of sign language and its implications for the neural basis of language
TL;DR: The linguistic abilities of 23 sign-language users with unilateral brain lesions were examined, and the view that the left-hemisphere dominance for language is not reducible solely to more general sensory or motor processes was supported.

Universal Grammar and American Sign Language: Setting the Null Argument Parameters
TL;DR: This article presented a cross-lingual survey of the use of null argument structures in ASL and discussed the learnability of null arguments and their learnability in the context of ASL.

On the nature of phonological structure in sign language
David P. Corina,Wendy Sandler +1 more
TL;DR: The authors compare spoken and signed languages in two modalities to establish modality independent linguistic universals, and accounting for modality-dependent structure and organisation, which is of theoretical importance for both reasons.
