Collective memories are often formed through the conversations community members have with each other. The effectiveness of these conversations to transmit a memory across a community and to produce a shared and stable mnemonic representation is constrained by psychological factors. This essay examines the effects of speakers' retellings of past events on listeners' memories and on their own memories. The first topic involves research investigating social contagion, resistance to influence, and induced forgetting. The second focuses on the saying-is-believing effect and (...) the creation of a shared reality. By illuminating these processes underlying transmission and convergence of individual memories, the essay provides new insights into the formation of their collective counterpart. (shrink)

Empirical research has increasingly turned its attention to distributed cognition. Acts of remembering are embedded in a social, interactional context; cognitive labor is divided between a rememberer and external sources. The present article examines the benefits and costs associated with distributed, collaborative, conversational remembering. Further, we examine the consequences of joint acts of remembering on subsequent individual acts of remembering. Here, we focus on influences on memory through social contagion and socially shared retrieval-induced forgetting. Extending beyond a single social interaction, (...) we consider work that tracks the propagation of socially shared retrieval-induced forgetting throughout larger networks made up of several agents. Although much work has focused on how distributing cognition can augment memory, this is not the primary lesson we draw from the conversational remembering literature. Rather, mnemonic convergence between communicators is a boon to sociality. It allows the formation and maintenance of mnemonic communities, rather than expanding capacity or accuracy of memory per se. (shrink)
