Thought Field Therapy (TFT) is a fringe psychological treatment developed by an American psychologist, Roger Callahan. Its proponents say that it can heal a variety of mental and physical ailments through specialized "tapping" with the fingers at meridian points on the upper body and hands.
Theory and treatment Callahan terms his treatment "Thought Field Therapy" because he theorizes that when a person thinks about an experience or thought associated with an emotional problem, they are tuning into a "thought field." He describes this field as "the most fundamental concept in the TFT system," stating that it "creates an imaginary, though quite real scaffold, upon which we may erect our explanatory notions".
Perturbations are said to be precisely encoded information contained in the thought field; each deformation of a person's thought field is connected to a particular problem, and is activated by thinking about that problem. Callahan maintains that these perturbations are the root cause of negative emotions and that each perturbation corresponds to a meridian point on the body. In order to eliminate the emotional upset, Callahan says that a precise sequence of meridian points must be tapped.
