 The Rusya Lab is a new Russian language assessment battery designed specifically for use with children aged 7 to 11 who have autism spectrum disorder, ASD. It measures their language skills in terms of phonology, vocabulary, morphosyntax, and discourse. This study found significant differences between children with and without ASD, as well as individual differences within the ASD group. Children with ASD were more accurate at repeating nouns than verbs and the frequency of words had an impact on their ability to repeat sentences. These findings suggest that the Rusya Lab can be used to accurately measure language abilities in children with ASD, providing valuable insight into their language development.
