Intérêt des aspects sémantiques et catégoriels dans le développement lexical des enfants de grande section maternelle présentant un déficit lexical réceptif et/ou expressif

Abstract : The development of the lexicon is a process that is the subject of continuous scientific research. The lexicon, more commonly referred to as "vocabulary", is a component of oral language in its own right but whose functioning interacts with other linguistic entities , in particular phonology and semantics. The principles that govern the acquisition of new words are multiple. However, the typical development of the lexicon is strongly correlated with categorization capabilities. Also, in the context of lexical deficits affecting the receptive and/or expressive sides, an approach based on semantics and phonology is put forward in speech therapy rehabilitation.
Thus, this study seeks to show the interest of semantic and categorical aspects in lexical development in children with lexical deficits in large kindergarten sections, with or without phonological disorders. The impact of a phonological disorder on the lexicon was also investigated.
The results show a benefit of the lexical semantics approach and categorization on word acquisition. The effect of spontaneous development could not be isolated and the impact of a phonological disorder could not be precisely quantified.
