Projective identification
Projective identification is a term introduced by Melanie Klein and then widely adopted in psychoanalytic psychotherapy. Projective identification may be used as a type of defense, a means of communicating, a primitive form of relationship, or a route to psychological change; used for ridding the self of unwanted parts or for controlling the other's body and mind.
