What Is Memory That It Can Be Changed? Lynne Nadel Multiple trace theory (MTT) makes two important claims. (1) Whenever the hippocampus is involved in the retrieval of episodic memories. (2) When a memory is reactivated, it becomes labile and must be reconsolidated, and within this window, there is a possibility that it can be changed. This raises two important questions. First, what is the function of consolidation? Consolidation allows us to integrate episodic memories with semantic memories or schemas. Put different, memory consolidation integrates “new experiences into established knowledge networks.” A major goal of psychotherapy is “to create momentary experiences that will lead to lasting changes in semantic memories or schemas.” Second, what is the advantage of having a malleable memory system? The answer is that as time passes we gather new information, and so it is adaptive to be able to update our memories to reflect this new information so that we in turn act accordingly. I
