Collaborative remembering, or group recall, did not increase errors compared to individual recall in initial tests. However, pairs demonstrated reduced correct and false recall, suggesting retrieval-strategy disruption.

Area of Science:

  • Cognitive Psychology
  • Social Psychology

Background:

  • Collaborative remembering involves group recall, contrasting with individual recall.
  • The Deese-Roediger-McDermott (DRM) paradigm is frequently used to study memory errors.

Purpose of the Study:

  • To investigate if collaborative remembering reduces correct and false recall compared to individual remembering.
  • To examine the effect of interpersonal closeness on collaborative recall accuracy.

Main Methods:

  • Three experiments utilized the DRM paradigm with word lists.
  • Participants studied and recalled word lists individually or in pairs.
  • Experiment 2 manipulated group closeness (friends vs. non-friends).

Main Results:

  • Experiment 1 found no difference in recall errors between pairs and individuals.

  • Experiments 2 and 3 showed that pairs (friends and non-friends) produced fewer correct and false recalls than individuals.
  • Results suggest retrieval-strategy disruption in collaborative recall.

    • Conclusions:

    • Collaborative remembering can lead to decreased correct and false recall, contrary to some expectations.
    • Interpersonal closeness did not significantly alter the pattern of reduced recall in pairs.
    • Retrieval-strategy disruption is a key factor explaining these findings in collaborative recall.
