Building a collective memory: the case for collective forgetting

https://doi.org/10.1016/j.copsyc.2018.02.002Get rights and content

Highlights

  • Studying collective memory involves exploring how individual memories become shared.

  • Selective remembering produces selective forgetting for both speakers and listeners.

  • The effects at the dyadic level can shape emergent outcomes at the community level.

The shared reality of a community rests in part on the collective memories held by members of that community. Surprisingly, psychologists have only recently begun to study collective memories, an area of interest in the social sciences for several decades. The present paper adopts the perspective that remembering is often an act of communication. One consequence of communicative acts of remembering is that speaker and listeners can come to share the same memories, thereby providing a foundation on which to build a collective memory. Another consequence is that the selectivity of communicative acts of remembering can induce collective selective forgetting, clearly one component of any collective memory. The phenomenon of retrieval-induced forgetting is discussed in the context of dyadic conversational exchanges of unrelated individuals and conversational exchanges between ingroup and outgroup members. In addition, the paper reviews work demonstrating that what occurs at the dyadic level can shape global outcomes of complex social networks, including convergence of memories across a network. The bottom-up approach described in this paper can help us understand how individual memories can come to be shared across a community.

Studying collective memory from a psychological perspective

Since Halbwachs's [2] groundbreaking work from the early 20th century, social scientists have studied collective memory by examining the role society plays in their formation and maintenance. For instance, scholars have examined the political context in which monuments are built and the way in which these monuments are reassessed as the political climate of a community changes (e.g., [3, 4]). Psychologists have largely approached the topic differently. Given their disciplinary inclinations,

A distinctively human way of remembering the past

We want to focus here on a distinctively human way of communicating about the past. Rather than just conveying new information to others, people will often talk to each other about things they already know. Just as Echterhoff et al. [1] underscored that people are motivated to create a shared reality for both epistemic and relational reasons, so also are people inclined to talk about a shared past to others for similar reasons. Faculty members jointly try to remember what was said at the last

Collective forgetting

Why does conversational remembering increase mnemonic convergence? (See [8] for an extensive discussion of this question.) One possible mechanism is reinforcement: because conversational remembering is inevitably selective [12, 13], what is mentioned will be reinforced, for both speaker and listeners, making it more accessible in the future [14, 15, 16]. Another possibility is that the selectivity of conversational remembering will selectively induce forgetting in speakers and listeners. This

Community-specificity of SSRIF

As we noted, collective memories are community-specific. Consequently, the cognitive mechanisms that govern their formation should be constrained in such a way that they promote the formation of a collective memory within a community as opposed to across communities. This appears to be the case for RIF, in that SSRIF is more robust when speaker and listener are members of the same group. This within-group bias occurs, presumably, because listeners are more motivated to concurrently retrieve if

Beyond the dyad

The just discussed research focuses almost exclusively on dyadic communicative interactions. Will the dynamics occurring at the dyadic level shape what occurs at a community level? (See [34] for a general discussion of a generative social science approach to community-wide behavior.) Several lines of research have explored this question as applied to collective memory. Using an innovative methodology that allowed them to examine experimentally established larger social networks, Coman et al. [35

Conclusion

In the beginning of this paper, we presented a challenge: to account for why communicative remembering among individuals would lead to shared memories specific to members of one community and not necessarily another. We addressed this issue by examining how selective remembering might lead to collective selective forgetting. Not only do speaker and listeners experience similar induced forgetting following selective remembering, this selective retrieval-induced forgetting is more robust when

      However, the present results call into question whether motivated victimization claims are reflected in individual short-term memory. Instead, the established low prevalence of individual memory distortions argues for the relevance of other mechanisms surrounding memory retrieval, such as selective confrontation with historical information, attribution processes or communicative effects (Hirst & Coman, 2018; Klein, 2013), in gaining a deeper understanding of the salience of collective victimhood narratives, that can be found in many different historical contexts.

      2022, Progress in Brain Research
      Citation Excerpt :

      Collective memory has a complex definition within psychology and neuroscience, embracing common memory, identity, and agency. Collective memories are currently defined as memories held in common across individuals within a social group; they are centrally important to the social identity of the group; and they loom large in the communal cognition, imagination, and agency of the group (Barnier and Sutton, 2008; Gagnepain et al., 2020; Hirst and Coman, 2018; O’Mara, 2023; Olick et al., 2011; Roediger and Abel, 2015; Wertsch and Roediger, 2008). As a shorthand, we describe these components (common memory, identity, and agency) as the “CIA” of collective memory.

      2021, Cognition
      Citation Excerpt :

      Roediger et al. suggested that covert retrieval in the form of rumination and overt retrieval in social interactions might enhance memory for events central to members of a certain group and thus shape collective memory. The latter has also been proposed by researchers examining social remembering in small-group conversations (e.g., Hirst & Coman, 2018; Rajaram & Pereira-Pasarin, 2010), suggesting that such retrieval might reinforce some, but cause forgetting of other memories, and support the emergence of overlapping and shared memories. The present data add to this perspective and suggest that memory retrieval of public events does not only occur in a deliberate and willful manner, but is equally likely to occur spontaneously, without any conscious attempts to recall the corresponding event, usually in response to cues in the ongoing situation.

      Citation Excerpt :

      The latter aspect suggests that collective memory is constructed through the reciprocal and dynamic interactions between individuals in a community and their attitudes and behaviors toward each other. Conversations among these members reinforce their collective memories, which contribute to the construction of shared realities [44•,45,46]. Culture is a macro phenomenon that is maintained through the psychological output and behaviors of individuals under specific social settings.
