Bilingualism influence on phonemic perception in children with autism spectrum disorders (ASD)

Supported by an RFBR grant 20-513-07005 «Bilingualism influence on phonemic perception in children with ASD»

The study of low-level processes of speech perception is an actual multidisciplinary problem facing neuroscience, clinical psychology and linguistics. Studies have noted in people with ASD violations of pragmatic functions of speech as well as grammar, morphology. However, most studies deal with high-level aspects of speech (pragmatics, discourse, etc.) or speech production disorders (Eigsti, 2011). And low-level mechanisms of speech perception (including phoneme discrimination) are described insufficiently detailed. /p>

Studies of children growing up in a bilingual environment have shown that the mechanisms of phonemic perception in them are significantly different compared to those for children who speak single language. The main difference is in the specificity of the errors and the temporal dynamics of mastering the basic speech functions (Hambly et al., 2014).

Studies of the effect of bilingualism on speech development in children with ASD are also devoted to the problems of high-level aspects of speech perception (Dai et al., 2018; Ohashi et al., 2012).

The novelty of our study is that we will for the first time study low-level mechanisms of speech perception in bilingual children with ASD. The aim of the study is to assess phonemic perception in the format of impressive and expressive speech in children with ASD speaking single language, compared with bilingual children with ASD. Thus, our approach can bring new knowledge about the mechanisms of perception of phonemes in the context of deficient communication skills for children with ASD, and let us develop recommendations for specialists of correctional and developmental sphere working with such children.
