Studie verbální produkce předškolních dětí s vývojovou dysfázií

Abstract

This study aims to analyse a range of the productive vocabulary and quality of verbal expression in Czech monolingual specific-language-impaired (SLI) preschool children. SLI children´s production was also compared to a verbal production of typically developing (age-matched) peers. An assessment tool was developed to measure the range and the quality of children´s production of nouns, verbs and adjectives. Both aspects of verbal production (the range and the quality) were also proved to be closely correlated. Research results reveal statistically significant differences between the SLI and a comparison group at both range and the quality of verbal expression. A more detailed examination shows that the differences between SLI and typically developing children´s production manifest themselves in the usage of adjectives the most and the least in the usage of nouns.
