Questions to Down Syndrome children

[Carol Slater]

Dear All:
I wonder whether you can help locate sources that might help a student who is comparing the number and kind of questions asked by caretakers of typically developing and Down Syndrome children? She is planning to base her investigation on the corpus contributed to CHILDES by Jean Rondal and is particularly interested in comparing the two groups with regard to frequency of yes-no questions and questions that can be answered nonlinguistically (e.g., by pointing). Suggestions will be greatly appreciated.
Sincerely,
