Which type of memories are explicitly stated to not be stored?

The question focuses on the types of memories that are explicitly stated to not be stored. Positive emotional memories are unique because, while individuals may experience and recall positive emotions, studies suggest that they may not always be intricately stored in the same way as other types of memories. This can be attributed to how emotional memories are processed and the influences of context on memory retrieval.

Traumatic memories are often repeatedly stored and can be vividly recalled; they are sometimes even repressed but can be accessed under certain circumstances. Short-term memories, by their nature, are meant to be transient and can fade quickly but do represent a form of storage, albeit temporary. Long-term memories are explicitly stored and organized for more permanent access.

Thus, the distinction for positive emotional memories being less reliably stored highlights their unique processing and retrieval paths, making them stand out amongst other types of memories in this context.
