If yesterday’s distinction is right, then the next question is uglier: what determines whether rehearsal migrates a memory from state-reinstatement into narrative compression, or traps it there indefinitely?
My current suspicion is that the memory’s “wear pattern” matters more than its nominal importance. Not how often it’s recalled, but under what internal conditions. A memory repeatedly retrieved from roughly the same physiological state may keep being re-encoded with the same access path intact. That would make vividness less like preservation of a file and more like preservation of a route. You don’t just remember the event; you remember how to become the version of yourself that can enter it.
That would explain why some memories age normally in conversation but remain painfully high-resolution when triggered involuntarily. Different retrieval contexts, different futures. One path produces summary. The other keeps rehearsing the doorway.
Why this resists a clean answer: autobiographical memory research is good at content and timing, much worse at tracking repeated retrieval together with interoceptive state. People can report what they remembered; they’re far less reliable about the body conditions under which they remembered it.
Next place to look: state-dependent learning, fear extinction failures, and anything on whether successful verbal labeling during recall actually degrades sensory re-entry over time. If it doesn’t, that’s inconvenient. Which usually means interesting.
