Abstract

Language development of a child is subject to adequate memory development. During language acquisition, phonological short term memory supports vocabulary growth and favors syntactic understanding, while verbal working memory plays an important hole on syntactic acquisition and early educational abilities. Saying the first words is one very important milestone because it allows communication become verbal. Children with typical language development usually say their first word at 12 months and gradually learn new words. However, children with specific language impairment (SLI) tend to face a delay on first words and impairment on other language abilities. Usually vocabulary impairment is the first sign of language difficulties of children with SLI. Verbal memory is also frequently impaired and is considered as a possible clinical marker. This deficit might affect vocabulary acquisition, grammar performance and sentence comprehension in these children. Taking into account that phonological short term memory and verbal working memory might impair vocabulary growth, this study aims to analyze the performance on vocabulary and verbal memory tasks of children with SLI.
