“…In sum, the current results support the integration concept of memory updating ( Gisquet-Verrier & Riccio, 2018 , 2019a ) in episodic memory. To our knowledge, this is the first test of this concept in human declarative memory.…”

“…Nonetheless, reconsolidation theory’s explanation of memory change faces some challenges. The memory integration concept ( Gisquet-Verrier & Riccio, 2018 , 2019a ) argues that effects such as updating or weakening are due to memory integration and state dependency. Specifically, rather than a memory trace starting out as fragile (or becoming fragile again upon reactivation), traces are said to be malleable during a particular window of time starting shortly before the memory forms or is reactivated and ending shortly afterward.…”

Reactivating a memory trace has been argued to put it in a fragile state where it must undergo a stabilization process known as reconsolidation. During this process, memories are thought to be susceptible to interference and can be updated with new information. In the spatial context paradigm, memory updating has been shown to occur when new information is presented in the same spatial context as old information, an effect attributed to a reconsolidation process. However, the integration concept holds that memory change can only occur when reactivation and test states are the same, similar to a state-dependent effect. Thus, in human episodic memory, memory updating should only be found when state is the same across the study, reactivation, and test sessions. We investigated whether memory updating can be attributed to state dependency in two experiments using mood as a state. We found evidence of memory updating only when mood was the same across all sessions of the experiments, lending support to the integration concept and posing a challenge to a reconsolidation explanation.

“…Contextual Binding assumes that the hippocampus supports the encoding and retrieval of episodic memory and remains necessary across time, while other structures, especially the neocortex, support different types of memory such as semantic. As previously emphasized, the Contextual Binding presents some aspects close to our view (see Gisquet-Verrier and Riccio, 2019a). However, an important difference is that despite the fact that the authors strongly emphasize that recent memories are highly susceptible to contextual changes, they do not consider the possibility that hippocampal lesions may constitute a major contextual change as we have proposed.…”
