Studies of collective memory have traditionally been the domain of philosophers and sociologists, while cognitive psychologists have largely investigated memory at the level of the individual. However, within cognitive psychology there is a variety of psychological theories and experimental paradigms that have been used to study the process and outcomes of remembering in groups. In this paper we review the research on group remembering and draw together findings from different traditions. In doing so, we aim to answer a series of questions about the outcomes and consequences of recalling in groups, and the particular features of groups and of memories that may be conducive to the formation of a collective memory. In clarifying what we know and what is yet to be studied about group memory, we point the way forward for a cognitive psychological study of collective memory.
