A study examined repair sequences in talk between two German-English bilingual children and between parent and child within a nuclear family in which German is generally spoken. Data were drawn from tape recordings and developmental diaries kept on the two preschool children. Patterns of parent-child and child-child corrections were examined. In parent-child corrections it was found that the father, a native speaker of American English, corrected most often for negative transfer from one language to another, primarily Germanisms brought into English usage. In contrast, the native German-speaking mother corrected primarily the error types monolingual German children make, particularly inflections. Repair was made most often in the turn just following the discrepancy. In child-child corrections, the older child began correcting his sister at age four years, three months. At first, corrections focused on facts, then on language usage and style, and subsequently on interference. Later he turned to giving explanations or appropriate contexts for the repair. At just five years, he made his first syntactic correction. The younger child did not correct her brother during the study. Overall, the repair patterns parallel those found in other studies. (MSE)
