Objectif This project investigates the acquisition of grammar in children with Down syndrome (DS), Specific language Impairment (SLI) and typical language development (TLD) between the ages of 2 and 12, speaking African American Vernacular English (AAVE) and Southern English (SE). Similarities and differences will be compared between the three populations to determine whether the reduced use of inflectional marking in AAVE speaking children is the result of linguistic illusions, conditioned by factors external to morphosyntax (i.e dialectal particularities). Children speaking AAVE are often referred to speech language pathologists for further assessment and intervention, because reduced production of overt inflectional marking resembles the speech of children with SLI. Similar characteristics have been argued for individuals with DS. Studies looking at DS and SLI comparatively find a number of similarities across the two populations. However, recent work on DS has shown that productions that may be seemingly due to a morphosyntactic impairment, are in fact “morphosyntactic illusions”, where the surfacing effect might seem to be a result of grammatical restrictions but it is in fact an effect caused by physiological/articulatory limitations and differences in the phonological system. The same has also been argued for toddlers with TLD.This study will provide information on the stages of language acquisition in the three populations and determine if the potential differences recorded across the three groups are the outcome of problematic language acquisition or linguistic illusions (phonetic/phonological effects, dialectal particularities, etc). Therefore, this project constitutes innovative research with regard to different stages of (a)typical language development across the three populations speaking AAVE and SE. We further aim to provide sufficient information for therapists for the development of new tools to improve linguistic performance in populations with DS and SLI Champ scientifique social scienceseducational sciencesdidacticshumanitieslanguages and literaturelinguisticsphonologyhumanitieslanguages and literaturelinguisticsphoneticssocial scienceseconomics and businessbusiness and managementemploymentsocial sciencespsychologypsycholinguistics Programme(s) H2020-EU.1.3. - EXCELLENT SCIENCE - Marie Skłodowska-Curie Actions Main Programme H2020-EU.1.3.2. - Nurturing excellence by means of cross-border and cross-sector mobility Thème(s) MSCA-IF-2016 - Individual Fellowships Appel à propositions H2020-MSCA-IF-2016 Voir d’autres projets de cet appel Régime de financement MSCA-IF-GF - Global Fellowships Coordinateur THE CHANCELLOR MASTERS AND SCHOLARS OF THE UNIVERSITY OF CAMBRIDGE Contribution nette de l'UE € 269 857,80 Adresse TRINITY LANE THE OLD SCHOOLS CB2 1TN Cambridge Royaume-Uni Voir sur la carte Région East of England East Anglia Cambridgeshire CC Type d’activité Higher or Secondary Education Establishments Liens Contacter l’organisation Opens in new window Site web Opens in new window Participation aux programmes de R&I de l'UE Opens in new window Réseau de collaboration HORIZON Opens in new window Coût total € 269 857,80 Partenaires (1) Trier par ordre alphabétique Trier par contribution nette de l'UE Tout développer Tout réduire Partenaire Les organisations partenaires contribuent à la mise en œuvre de l’action, mais ne signent pas la convention de subvention.
