The basis of Authentic Movement, pioneered by Mary Whitehouse, Joan Chodorow, and Janet Adler, is the differentiation of mover and witness

Unlike performance, however, neither person has any agenda.  The mover moves in any way they like, usually with eyes closed.  The witness stays mindfully present.  Afterward there is generally some verbal reflection on the experience, traditionally in the first-person present tense.  This way of speaking supports the meaning making process as belonging to each individual, and not a property of the movement itself.  The process can be quite insightful and therapeutic, deconstructing layers of somatic experience for both mover and witness.
