I think it's very difficult to be sure that counter transference is active, and what form it takes, without talking about it. And unless it takes on an over riding pattern, rather than just a fleeting instance, I'm not sure it matters.

What I understand of attunement is that it's a way of aligning with another person, physically or emotionally, and is often expressed through the technique of mirroring. It can be conscious, or unconscious. It's supposed to make the client feel validated and at ease. It goes back to how mothers and infants engage, through eye contact and reflecting back expressions.

Not sure your T's eye contact means she was nervous; I don't know how you could know without talking about it.
