Objective

To assess linguistic productivity and complexity, grammatical and referential accuracy, event, content, the use of mental state expressions and narrative comprehension in children with SLI

To assess the relative strength of content elaboration and grammatical accuracy of the narratives of each child with SLI

To analyze the oral narratives and the sustained

auditory attention and verbal working memory capacities of children with SLI in comparison

with their chronological-age peers

To find out whether language productivity measures, (MLU), (%UGS), (TNW), and (NDW) produced by young children during a story retell task, can be used to accurately differentiate monolingual Spanish-speaking children with SLI from TD children

To compare the development of oral language and more specifically narrative skills (storytelling and story retelling) in children with specific language impairment (SLI) with and without literacy delay

To identify the development of morphosyntactic accuracy and grammatical complexity in

Dutch school-age children with specific language

impairment (SLI)

Test of Narrative

Language

(TNL; Gillam & Pearson, 2004 ) and analysis of the story texts

A story retelling task (The Bus Story) and a story generation task (The Frog Story)

Picture Scripted book-retelling of s story
