What is collective about collective memory? Two different concepts of colle
ctive memory compete-one refers to the aggregation of socially framed indiv
idual memories and one refers to collective phenomena sui generis-though th
e difference is rarely articulated in the literature. This article theorize
s the differences and relations between individualist and collectivist unde
rstandings of collective memory. The former are open to psychological consi
derations, including neurological and cognitive factors, but neglect techno
logies of memory other than the brain and the ways in which cognitive and e
ven neurological patterns are constituted in part by genuinely social proce
sses. The latter emphasize the social and cultural patternings of public an
d personal memory, but neglect the ways in which those processes are consti
tuted in part by psychological dynamics. This article advocates, through th
e example of traumatic events, a strategy of multidimensional rapprochement
between individualist and collectivist approaches.
