Abstract
The aim of this study is to investigate phonology (via consonant clusters) and sentential semantics (via exhaustivity in wh-questions) regarding their potential to characterize SLI in the context of bilingual acquisition. Using the German LITMUS-QU-NWR task and the exhaustivity task, the phonological and semantic abilities of 5- to 6-year-old simultaneous-bilingual (2L1) and early second language (eL2) learners of German with SLI were compared to their typically developing peers. The results suggest that in this age group language-dependent phonological knowledge regarding consonant clusters is a marker of SLI for 2L1 and eL2 children, while language independent knowledge of consonant clusters is a marker of SLI only for eL2 children. At age 5 to 6, exhaustivity is not a marker of SLI in either bilingual group. Consistent with the notion of subtypes of SLI, individual analyses revealed considerable heterogeneity within the two SLI groups. We argue that characterization of bilingual SLI requires analyses of group and individual data, and moreover, consideration of the age at testing in relation to timing in monolingual acquisition. The COST-tasks are suitable for combining both approaches.
