Due to the lack of consensus about terminology in the study of DID, several terms have been proposed. One is ego state (behaviors and experiences possessing permeable boundaries with other such states but united by a common sense of self). Another is alters (each of which may have a separate autobiographical memory, independent initiative and a sense of ownership over individual behavior).
