divided consciousness

Ernest R. Hilgard’s characterization of dissociation as a state in which one stream of mental activity (e.g., perception, memory, planning) proceeds outside of phenomenal awareness and apparently outside of voluntary control. In his neodissociation theory, Hilgard proposed that this state could be best studied through hypnosis. See also coconsciousness; unity of consciousness.
