Lexical development, speech language disorders and school performance: literature review

Abstract: Lexical development is directly related to the ability to understand and produce various kinds of meanings. The mental lexicon is accessed to represent an object, an attribute or any other information. The word learning process and the association of words are necessary for the lexical development. The purpose of this study is to analyze and compile findings about the relationship between lexical development, speech disorders, phonological awareness, school performance and auditory processing through literature review. The scientific productions found in this review suggest the relevance of lexical development for the phonological acquisition and subsequent written language acquisition. Regarding phonology, they show the importance of appropriate lexical development for the effective phonological acquisition.
