This malleability of memory has important implications, for public and private spheres of life.
The dynamic nature of memory is probably not a design flaw; it can allow us to update existing knowledge in light of new information.
The reactivation of a memory through retrieval can render it subject to disruption or modification through the process of memory reconsolidation. The authors declare no competing financial interests.
In both humans and rodents, briefly reactivating a fear memory results in effective erasure by subsequent extinction training.
While a relatively stable and fixed core knowledge seems essential for successful everyday functioning and high-level concepts such as self-identity, the ability to forget outdated information and to update memories in the light of new relevant information is equally important.
Understanding the dynamics of memory change is the central focus of my research agenda.
It is assumed that through reactivation, a particular memory is transferred from a passive and stable state to an active but fragile state, at which time it can then be modified.
We present snapshots of our current knowledge and gaps in knowledge concerning the progress of consolidation over time and the cognitive architecture that supports it and shapes our long-term memories.
However, when in a novel context, updating of existing memories does not occur, and a new episodic memory is created instead.
Memory does not provide a perfect record of the past and can be altered long after acquisition.

One particularly common example of context-dependence at work occurs when an individual has lost an item (e.g. Typically, people try to systematically "retrace their steps" to determine all of the possible places where the item might be located.
