These tapes are also very good and are created by a PHD Clinical Psychologist. He uses an Ericksonian approach with double induction so they are a little like the Paraliminals. They tend to be longer than paraliminals at 35 to 40 minutes.
I have the tape called "Performance 2" and I have found it to be good for dealing with anxiety about speaking in front of groups.
I would buy more of his tapes but unfortunately they are a bit expensive at $30 a piece.
He is very helpful if you send him an e-mail. He could probably tell you which tapes or combination of tapes would be best for the situation you are dealing with.
