I'm new here (Hi!), but we just had our 9yo Dd tested with an OT recently. During the memory portion of the test, she mouthed the letters she was to remember (short term memory).
I think it's a kinesthetic memory technique. Dd is very verbal and, while I don't recall seeing her do this in other circumstances, I'm guessing she did. She also *never* talked under her breath - ALWAYS out loud! LOL!
I do something similar with music - my hands remember it much better than my brain. And, when remembering/reciting things, my mouth will remember the words to form even when my braing isn't "engaged" in the recall. In fact, if I stop to think about the words, I can't bring them to mind!
HTH!
