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.

Dissertation
Towards an Integrative Information Society: Studies on Individuality in Speech and Sign
TL;DR: Speech and sign are discussed as equal and analogical counterparts of communication and all research methods used in speech are modified for sign, and both production and perception of speech andSign are studied separately.

Effects of age on the temporal organization of working memory in deaf signers.
TL;DR: The findings suggest that apart from age-related slowing irrespective of sensory and language status, there is an age- related difference specific to deaf signers in the ability to retain order information in WM when temporal processing demands are high.

The Impact of Developmental Visuospatial Learning Difficulties on British Sign Language
TL;DR: The case of Heather, who is remarkably similar to the characteristic phenotype of Williams syndrome in physical appearance and cognitive abilities, but who is also congenitally deaf and a user of British Sign Language, provides the first opportunity to explore the consequences of specific visuospatial learning difficulties on the linguistic system when the language used is visuOSPatial.

The signs of a Savant: Language against the odds
TL;DR: Smith,Ianthi Tsimpli, Gary Morgan and Bencie Woll 2011 as mentioned in this paper, documents his learning of British Sign Language, casting light on the modularity of cognition, the modality neutrality of the language faculty, the structure of memory, the grammar of signed language and the nature of the human mind.
Modalities of Mind : Modality-specific and nonmodality-specific aspects of working memory for sign and speech
TL;DR: Language processing is underpinned by working memory and while working memory for signed languages has been shown to display some of the characteristics ofWorking memory for speech-based languages, there is still room for further research into this area.

The signs of language

TL;DR: The two faces of sign and sign language have been studied in this paper, where the authors compare Chinese and American signs and feature analysis of handshapes and the rate of speaking and signing.

What the hands reveal about the brain
TL;DR: This paper showed that there are primary linguistic systems passed down from one generation of deaf people to the next, which have been forged into antonomous languages and are not derived from front spoken languages.

The acquisition of American Sign Language.
TL;DR: The authors compare the acquisition of American Sign Language (ASLSA) with the acquisition process of spoken languages, and delineate those aspects of acquisition which are universal over languages of varying types, and those aspects which are specific to certain linguistic and modality-related typologies.
