It's interesting to see this done as a deliberate procedure. I thought everyone did that almost instinctively, as if telling themselves "OK, focus". I certainly do it, except for the vocalising. Even just doing a generic pointing gesture at nothing when trying to think through something unrelated to the physical world. I wonder if those trained to do it deliberately are trained to use the right hand regardless of their natural preference, since the left side of the brain is more associated with focus and logical thinking.
