By the age of 8 months (pre-speaking stage) babies make inarticulate voices, babbling predominates and by the end of the first year the peculiar phonological ensembles dominate.
Typical Language Development at Preschool and Early School Ageįrom infancy, children begin to understand the structure, use, and meaning of language (Ralli & Sidiropoulou, 2012), and gradually use monosyllabic phrases or two-word phrases to communicate (McCabe & Rollins, 1994).
Especially for bilinguals with DLD storytelling tasks are challenging and can be used to differentiate them from their typically developing (TD) peers since lack of knowledge, normative data, and tools may often lead to over or underdiagnosis of language deficits in bilingual population (Laasonen et al., 2018).Ģ.1. Given that children with DLD/SLI appear to be increasing in recent years in the classroom, storytelling assessment can generally provide specialists with important information on the language skills of these children. Children’s narrative skills seem to be related to overall school and reading success as well as early mathematical ability (Boudreau, 2008 Justice et al., 2010). The production and understanding of narrative speech are very important in preschool and early school age. Microstructure seems to be greatly affected by DLD with macrostructure being affected the less. No significant difference is observed in the performance between monolinguals and bilinguals of typical language development, yet performance differences are noted between monolinguals with DLD and bilinguals with the same language impairment. The majority of studies reported significant differences in the narrative performance between monolinguals with and without DLD and between bilinguals with and without DLD. The selected studies fell under three main areas: 1) studies assessing the narrative skills of monolingual children with DLD/SLI, 2) studies comparing bilingual children of typical development and bilinguals with DLD/SLI and 3) studies comparing monolingual and bilingual children with DLD/SLI. Therefore, it focuses on 13 research articles published since 2010 until present that met the inclusion criteria set in this review. The objective of this paper is to conduct a systematic review of recent studies on the narrative skills of monolingual and bilingual pre-school and primary school children with DLD.
A method that has often been used to investigate the language features of monolingual and monolingual children with DLD is to examine their narrative abilities, since narratives provide a quasi-naturalistic measure of children’s spontaneous language and reflect distinctive structural linguistic changes through childhood and adolescence. Research has shown that when it comes to bilinguals with language deficits caution should be taken, since they may arise from impairment due to DLD but can also be caused by insufficient exposure to and limited knowledge of the target language (Reilly, Losh, Bellugi, & Wulfeck, 2004). The language characteristics of children with DLD vary considerably with the main challenge being the learning of language structures and morphosyntactic and lexical limitations (Leonard, 2014). Developmental Language Disorder (DLD), previously known as Specific Language Impairment (SLI), is a common developmental disorder that affects both preschool and school aged children.
