The Mental Lexicon in Dyslexic Children An Overview of the Effect of Orthographic Variability

Main Article Content

Abstract

The mental lexicon is accessible in each act of linguistic communication, due to the permanent need to find words that designate what we need to transmit as messages or to understand the words we hear or read. In the context of the processes of deciphering and visual recognition of words, it is widely accepted that reading depends significantly on the subject's ability to access the mental lexicon of their language, itself determined by two main parameters: precision and access speed. However, in children suffering from learning to read disorders, or developmental dyslexia, the difficulty of accessing the mental lexicon repertoire, generally assessed by the experimental paradigm of automated rapid naming (RAN), is almost regularly identified. but it varies according to the level of graphophonological consistency (grapheme-phoneme correspondence) which characterizes the language in question. In this work, we address the question of the relationship between access to the mental lexicon and reading through a brief review of work on dyslexia in different orthographic systems, and through a presentation of some data from a study pilot on certain aspects of difficulties which characterize access to the lexicon in dyslexic children in comparison with normal readers matched in chronological age.
