The studyĄ¯s hypotheses were that (1) the mother would start by offering repairs and later in development use strategies to lead the child towards self-repair; (2) she would focus on repairing different linguistic levels at different stages of the childĄ¯s development; (3) she would favor the flow of communication over formal correction; (4) the child would progressively detect mismatches between her input and her output and self-repair her own productions. The results showed that the mother frequently intervened at first by offering direct and indirect repairs but progressively elicited the childĄ¯s own repairs through repair initiations. Repairs were thus often co-constructed through multiple turns before being fully initiated by the child. The mother and childĄ¯s repairs targeted different linguistic levels according to the childĄ¯s development and to her age %K Acquisition %K child language %K French %K interaction %K repairs %U https://journals.sagepub.com/doi/full/10.1177/0142723718803155
