Amnesic Barriers

amnesic barriers:

Amnesic barriers are barriers in a system that prevent headmates from remembering what other headmates have done, or remembering trauma or events another headmate may hold. It also can protect headmates from being known by the system, to protect the core or host's identity.

This term is most often used for DID systems, but also applies to OSDD-1a.

Breaking an amnesic barrier before its time may be traumatizing for the system; these walls are often constructed to quarantine trauma knowledge.

Amnesic barriers fall under an umbrella type of amnesia, called functional amnesia or psychogenic amnesia. While not the same, dissociative amnesia is similar to amnesic barriers, albeit it is not restricted to systems and usually applies to traumagenic systems. Systems can have both dissociative amnesia and amnesia barriers separately, or have just one.

Integration often involves lowering amnesia barriers to increase communication and cooperation.

Perceptual barriers are another type of barrier that can distord perceptions, often for protection purposes similar to amnesic barriers. They can make a system member avoid spoilers, and they can prevent access to memories that a specific member should not know about (the others do not feel or see the distortion effect).

Another type of internal barriers include communication barriers.
