Three experiments examined the effects of passage type on both individual and collaborative memory performance. In Experiment 1, both individuals and collaborative groups recalled more information from passages containing social information than non-social information. Furthermore, collaborative inhibition (CI) was observed for both types of passages. In Experiment 2, which included a social passage that did not contain gossip, significant main effects of both gossip (gossip > non-gossip) and sociability (explicit > implicit) were observed. As in Experiment 1, CI was observed across all conditions. Experiment 3 separately manipulated gossip and the interest level of the passages and both of these factors enhanced memory performance. Moreover, robust CI was again observed across all conditions. Taken together, the present results demonstrate a mnemonic benefit for social information in individuals and collaborative groups.
三个实验考察了篇章类型对个体和合作记忆表现的影响。在实验 1 中，个体和合作组从包含社会信息的篇章中回忆出的信息多于不包含社会信息的篇章。此外，两种类型的篇章都观察到了合作抑制（CI）。在包括一个不包含八卦的社会篇章的实验 2 中，观察到了八卦（八卦>非八卦）和社交性（显式>隐式）的显著主效应。与实验 1 一样，在所有条件下都观察到了 CI。实验 3 分别操纵八卦和篇章的趣味性，这两个因素都增强了记忆表现。此外，在所有条件下都再次观察到了强大的 CI。总之，这些结果表明，个体和合作组对社会信息有记忆优势。
