Leaping across the mental canyon: higher-order long-distance analogical retrieval

Previous experiments have shown that a comparison of two written narratives highlights their shared relational structure, which in turn facilitates the retrieval of analogous narratives from the past. However, analogical retrieval occurs across domains that appear more conceptually distant than merely different narratives, and the deepest analogies use matches in higher-order relational structure. The present study investigated whether schema abstraction can facilitate analogical retrieval of higher-order relations across written narratives and abstract symbolic problems. Participants read stories which became retrieval targets after a delay, cued by either analogous stories or letter-strings. We replicated prior research that used narrative retrieval cues, and also found clear evidence that a comparison of analogous letter-string problems and explanation of the underlying principle facilitated the retrieval of source stories with analogous higher-order relations. These findings show that the schemas abstracted from comparison of narratives can be transferred to non-semantic symbolic domains.
