By the way, INTPs also have Ne as well as ENTPs. For INTP it is an auxiliary function, so it works a little different than for ENTPs and ENFPs.
For me, Ne shows up often with eye movement (because it is an explorative function). I joked with Auburn once and said Ne-dominants have "coffee eyes", like they are hopped up on caffeine all the time. Fi, which is auxiliary for ENFP, lends to something called "unaware" mouth, which almost literally translates to their jaw movement. Its kind of weird. You should email Auburn (if he's still doing this these days) to ask him more specifically about what might be expected from all the functions and then you will know what he's talking about. I've just seen it so many times now that I can recognize it when I have enough exposure to it.
