Distributed Memory and Loss of Retrieval Connections: Why Two People Can Recall Together What Neither Recalls Alone
Year: 2026
Type: article
Abstract: This conceptual paper introduces Distributed Memory and Loss of Retrieval Connections, a structural account of how complementary cues held by different people make a shared history accessible through interaction. Removing the connection can make parts of that history inaccessible even when individuals retain what they previously held. The account compares what each person recalls alone with what the arrangement retrieves together and traces specific connections between cues and memories. Collaborative recall can improve retrieval or interfere with it. Any advantage requires evidence of complementary material and effective retrieval routes; remembering together does not guarantee better recall. The discussion connects the mechanism to Wegner, Erber, and Raymond’s work on transactive memory and examines Harris and colleagues’ study of older married couples. The study reports both collaborative facilitation and inhibition, alongside conversations in which one spouse’s cue prompted the other’s recall. Its fixed testing order limits causal conclusions from overall score differences. Part of the Shared Capacity and Learning series within On Human Modeling, the paper distinguishes individual retention from access sustained through relationships. Its framework can inform human–AI research on complementary memory support, retrieval dependencies, and what becomes inaccessible when a supporting connection is removed.
