yes, that makes perfect sense. She actually has wonderful attention and was very focused, but my sense is that she was hiding more than she presented even though to them it seemed noteworthy. I am sure that it true of most three year olds and that plent of them were "hiding" skills because of lack of focus. She was focused intently and so some of her wrong answers are a mystery to me since they are things she clearly knows. I get a sense there would be less of that in a few years for all children.
