Evaluating the role of word-related parameters in the discriminative power of a novel nonword repetition task for bilingual children.

In bi- and monolingual children, nonword repetition tasks (NWRTs) differentiate typically developing (TD) children from children with Developmental Language Disorder (DLD) or children with a risk of DLD. Previous research has highlighted the importance of considering language specificity in nonword (NW) construction especially for bilingual children. A novel NWRT has been designed for the screening of DLD risk in the bilingual Italian-German preschool population, creating lists of language-specific (for the two target languages) and language-non-specific NWs. This study aimed to test the discriminative validity of this NWRT and to identify the characteristics of the NWs that maximise discriminative validity within language-specific and language-non-specific subsets. The findings confirm the role of language specificity (in terms of target language alikeness) but also of other characteristics related to word structure complexity. [ABSTRACT FROM AUTHOR]
