Measuring language development in bilingual children: Swedish- Arabic children with and without language impairment

Data from ten Swedish-Arabic preschool children with language impairment and ten Swedish-Arabic children with normal language development matched for age and exposure to Swedish were analyzed. Specific tasks for both Swedish and Arabic were designed. By using the hierarchy predicted by processability theory as a yardstick, grammatical development was measured in the two languages of the children. The basic assumption is that there is a developmental sequence that all language learners follow on their way toward a target language. The results show that the bilingual children with language impairment tend to have a balanced low level of language development in both languages, whereas the bilingual children with normal language development show a higher level of language development in at least one language
