Mnemonic convergence in social networks: The emergent properties of cognition at a collective level
Open accessAbstract
Significance: Human memory is highly malleable. Because of this malleability, jointly remembering the past along with another individual often results in increased similarity between the conversational partners’ memories. We propose an approach that examines the conversation between a pair of participants as part of a larger network of social interactions that has the potential to reveal how human communities form collective memories. Empirical evidence indicating that dyadic-level conversational alignment processes give rise to community-wide shared memories is presented. We find that individual-level memory updating phenomena and social network structure are two fundamental factors that contribute to the emergence of collective memories.

Synchronization among individuals at a local level leads to the emergence of collective memories and beliefs at a community level.
“And third, synchronization among individuals at a local level leads to the emergence of collective memories and beliefs at a community level (Coman et al., 2016).”

The Abstract and Discussion (page numbers unavailable) report that local conversational processes and network structure contribute to collective memories in laboratory-created communities. The Abstract also describes shared beliefs as an emergent outcome thought to arise through communication, but the study does not establish that local synchronization leads to collective beliefs.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
