Nope, I don't think larger numbers would have substantially changed our results -- though of course I see why you're asking, because if you're thinking in terms of group studies then 8 children seems like a relatively small number. I think it was Erin and Amy's question, not too far up in the list above yours, that got me going about the hundreds of kids in the literature who have responded to similar direct procedures -- maybe you've read that already by now. And the beauty of single-subject experimental designs is that you don't need very large sample sizes to develop some relatively believable answers to some particular questions -- eight is actually rather large for a single-subject design experiment. Thanks for your interest!
