> I'd be interested to know if others count by 1, 2, 3, or something else. I count in 1,2,3,4 or 5 blocks depending on the situation. For example if I am supposed to have 13 buttons and I want to verify it. I visually or physically separate 5, then another 5 and then check the remaining buttons. If it is 3, then I have verified it. Anything above 5 gets harder and harder to distinguish. I could easily and naturally spot 1, 2, 3, 4 or 5 items. But if it gets higher than that, it gets harder for me to distinguish between a group of 7 or 8 or 9 items.
