Anecdotally, some human kids don't like being tested and will deliberately fuck with a researcher. (I don't remember this, my mother was hidden behind a one way mirror.) I had some pretty severe co-ordination issues as a child, no learning related problems - but fuck knows who decided that I needed to be evaluated on both fronts. Anyway this woman comes in to test me with one of those boxes with different shaped holes in the top, and a matching block for each hole. I grab a random block and try to shove it in a hole into which it obviously does not fit - and keep trying with the same hole until the woman gets up and leaves in frustration (she'd been trying to hint that I should perhaps try another hole). The moment she left I quickly solved the puzzle.
