Mystic writing pad model: a model of memory based on a toy writing tablet that retains fragments of old messages even after they have been "erased". In time, these fragments accumulate and begin to overlap, so that they become increasingly hard to read. Reappearance hypothesis: neisser"s term for the new rejected idea that the same memory can reappear, unchanged, again and again. Flashbulb memories: vivid, detailed memories of significant events. Theory: the theory that especially significant experiences are immediately "photocopied", preserved in long-term memory and resistant to change. Consolidation theory: the classic theory that memory traces of an event are not fully formed immediately after that event, but take some time to consolidate. Retroactive interference: a decline in recall of one event as a result of a later event. Reconsolidation: the hypothetical process whereby a memory trace is revised and reconsolidated. Method of repeated reproduction: one participant is given multiple opportunities to recall a story over time.
