Alters in Dissociative Identity Disorder
People with DID have alters, which are different identities that are independent of each other and thus, occur separately. Each alter has its own personality, set of behaviors, unique memories, and may speak a different language. Switching between alters often includes changes in behavior, including eye blinking and rolling and changing posture. Alters are theorized to stem from traumatized children not being able to form one stable identity used across different situations.

The patient has no recollection of these behavioral changes. Which of the following statements best synthesizes these core symptoms into a coherent psychological phenomenon?
