Dissociative Identity Disorder: Inter-identity Amnesia and Sense of Self Across Time
Laboratory research continues to explore the complexity of dissociative identity disorder (DID) as fleshed out in the clinical literature. The nature of reported amnesia between dissociative identities has been a central topic of empirical and clinical interest, and laboratory studies have sought to determine the degree to which information is inaccessible to recall by other identities. Another topic of conceptual interest to understanding DID is the nature of self-continuity, or the experience of sense of self over time in dissociative identities. This presentation outlines recent research exploring episodic memory retrieval across identities reporting amnesia for each other. In addition, it also explores diachronicity unity, the sense of self over time in dissociative identities. This work has been conducted using both experimental paradigms and survey designs. Results show evidence of memory accessibility even in cases that reported inter-identity, suggesting that at least in some cases, amnesia may be more related to metacognitive rather than cognitive processes, and that self-continuity may be somewhat tenuous at least in some dissociative identities.
Potential to Distress: No
Upon completion of this webinar participants will be able to:
- Recognize the nature of inter-identity amnesia in DID
- Explore self-continuity in dissociative identities
- Describe the latest findings on inter-identity amnesia and self-continuity in DID
