People talk a lot about the sharing of memory between alters. This idea of memory sharing tends to be viewed on a spectrum. Either you have a lot of memory sharing, or not much memory sharing, people seem to think.
Many people don’t realize that there are many different kinds of memory. Long-term memory (“I attend Middleton High School.”), short-term memory (“What homework do I have tonight?’) or working memory (“What did I just get up to do?”), procedural memory (“How do I solve this problem?”), declarative memory (“I went to gym class today.”), sensory memory (“It smelled terrible!”).
In our system, the different types of memory have different degrees of strength. Long-term memory usually pretty crisp, unless someone has deliberately suppressed or hidden a memory. Working memory is surprisingly well-shared, so that if a switch occurs mid-task, the task will be completed successfully more often than not. Procedural memory has almost no sharing. Declarative memory is pretty variable, and sensory memory is pretty hazy.
What do you remember?
This is definitely a good question to think about, I’ve always wondered the difference between types of memory and how each of us processes memory. I think I can only speak for myself in this matter, and my ability to remember changes largely on what’s going on or what stress I’m experiencing.
Working memory seems to function just fine. We can move through tasks depending on preferences or motivation of the individual. There has been one individual where working memory and declarative memory was blocked and that’s Addius/Aria. She was only present for a few months, it was really frightening for me because memories typically carry on from individual to individual pretty well.
This is something I want to do more research on and I might be able to answer it better, and come to better understand how we function among each other.
