Free Attention is being present for your Client in a non-judgemental way, witnessing them with a warm heart while keeping eye contact on offer all the time.
Caril Rogers of Person Centred Counselling calls this Unconditional positive regard'. The attention for the client is as free as possible from internal chatter and external distractions. It implies also awareness of those inner states that signal that one gets a bit carried away with the material the Client is working on. This type of distraction is called Restimulation.
In a Free attention Contract the counsellor supports the client with nothing else than his Free Attention presence.
