THE ROLE OF VISUAL MODALITY IN LANGUAGE VITALITY AND MAINTENANCE
The paper discusses sociolinguistic aspects of Russian Sign Language (RSL) and attempts to show that the tools used to access the degree of language vitality, which were developed for spoken languages, are not quite suitable to access vitality of sign languages. For example, if to try to assess the vitality of RSL in terms of six-point scale of the “nine factors” system proposed by UNESCO (Language vitality ..., 2003), which is used in the Atlas of Endangered Languages, the assessment of RSL would be no more than 3 points. In other words, RSL would be characterized as an endangered language. It is an unwritten language, mainly used in everyday communication; it exists in the environment of functionally much more powerful spoken Russian; the overwhelming majority of RSL signers are bilinguals, they use spoken Russian, at least in its written form; most deaf children acquire RSL not in the family, from birth, but later in life, at kindergartens or schools; the conditions of RSL acquisition affect the deaf signers’ language proficiency, as well as spoken Russian affects RSL’s lexicon and grammar; RSL still remains insufficiently studied and poorly documented, etc. However, RSL, as a native communication system of the Deaf, based on visual modality, is not only well maintained, but even expands some spheres of use. The main factor, which supports maintenance of RSL and which is not taken into account in the existing tools to access the degree of language vitality is visual modality. The auditory modality is inaccessible or poorly accessible for the deaf, so they can not completely shift to spoken Russian. Visual modality remains the most natural for their communication. In addition, modern technologies and the internet provide much more opportunities for the existence of RSL in this modality and for its development.
