Editing Collective memory (section)

====Forgetting====
Studies have shown that information forgotten and excluded during group recall can promote the forgetting of related information compared to information unrelated to that which was excluded during group recall. Selective forgetting has been suggested to be a critical mechanism involved in the formation of collective memories and what details are ultimately included and excluded by group members. This mechanism has been studied using the socially-shared retrieval induced forgetting paradigm, a variation of the [[Retrieval-induced forgetting|retrieval induced forgetting method]] with individuals.<ref name =unforgettable>{{Cite journal|last1=Coman |first1=Alin |last2=Manier |first2=David |last3=Hirst |first3=William |date=May 2009 |title=Forgetting the unforgettable through conversation: socially shared retrieval-induced forgetting of September 11 memories |journal=Psychological Science |volume=20 |issue=5 |pages=627–633 |doi=10.1111/j.1467-9280.2009.02343.x|issn=1467-9280|pmid=19476592|s2cid=5936888 }}</ref><ref>{{Cite journal|last1=Coman |first1= Alin |last2=Hirst |first2=William |date=August 2015 |title=Social identity and socially shared retrieval-induced forgetting: The effects of group membership |journal=Journal of Experimental Psychology.

These structures in the brain are required for attaining new information, and if any of these structures are damaged you can get anterograde or retrograde amnesia (Anastasio et al.,p.&nbsp;26, 2012).<ref>{{Cite book|last1=Anastasio|first1=Thomas J.|last2=Ehrenberger|first2=Kristen Ann|last3=Watson|first3=Patrick|last4=Zhang|first4=Wenyi|date=2012|title= Individual and Collective Memory Consolidation|doi=10.7551/mitpress/9173.001.0001|isbn=978-0-262-30166-4}}</ref> Amnesia could be anything that disrupts your memory or affects you psychologically.
