=== Synchronization of memories from dyads to networks ===
Bottom-up approaches to the formation of collective memories investigate how cognitive-level phenomena allow for people to synchronize their memories following conversational remembering. Due to the malleability of human memory, talking with one another about the past results in memory changes that increase the similarity between the interactional partners' memories<ref name="unforgettable" /> When these dyadic interactions occur in a social network, one can understand how large communities converge on a similar memory of the past.<ref name=":5">{{cite journal | last1 = Coman | first1 = A. | last2 = Momennejad | first2 = I. | last3 = Drach | first3 = R. | last4 = Geana | first4 = A. |year = 2016 | title = Mnemonic convergence in social networks: The emergent properties of cognition at a collective level. | journal = PNAS | volume = 113 | issue = 29| pages = 8171–8176| doi = 10.1073/pnas.1525569113 | pmid = 27357678 | pmc = 4961177 | bibcode = 2016PNAS..113.8171C | doi-access = free }}</ref>{{Elaboration needed|reason=|date=October 2018}} Research on larger interactions show that collective memory in larger social networks can emerge due to cognitive mechanisms involved in small group interactions.<ref name=":5" />
