Influence of others on true and inauthentic memory both during and after collaborative remembering have drawn extensive attention in recent years. Collaborative research has recorded three typical effects: collaborative inhibition and error pruning (i.e., nominal groups recall more true information but also bear higher erroneous intrusions than collaborative groups) during collaboration, as well as post-collaborative recall benefit after collaboration. This study introduced Deese-Roediger-McDermott (DRM) lists not only to investigate these phenomena in semantically related information, but also set a course to explore false memory in the collaborative context. Another issue is the sensitivity of these effects to different episodic memory tests (i.e., item memory and source memory tests). In views of these, the current study instructed participants to study several DRM lists and then recall previously studied words (item recall) together with their displayed colors (source retrieval) twice (Recall 1 and 2). Recall 1 was performed either individually or collaboratively, whereas Recall 2 was conducted individually. The cost of collaborative inhibition was obtained, along with three different beneficial effects: error pruning, false memory reduction, and post-collaborative recall benefit. Furthermore, the novel implication of the current study is that it reveals the sensitivity of collaborative inhibition and error pruning in DRM lists to testing conditions and demonstrates that the modulation of collaboration on false memory occurs in the same way both during and after collaboration. These results are discussed in terms of the retrieval strategy disruption hypothesis and other accounts.
近年来，他人在协同记忆期间及之后对真实记忆和虚假记忆的影响受到了广泛关注。协同研究记录了三种典型效应：协同过程中的协同抑制和错误修剪（即名义小组比协同小组回忆起更多真实信息，但也承受更高的错误侵入），以及协同后的协同回忆益处。本研究引入了迪斯-罗迪格-麦克德莫特（DRM）词表，不仅要在语义相关信息中研究这些现象，还要着手探索协同情境下的错误记忆。另一个问题是这些效应对不同情景记忆测试（即项目记忆和来源记忆测试）的敏感性。鉴于此，本研究指示参与者学习几个DRM词表，然后两次回忆之前学习的单词（项目回忆）及其显示的颜色（来源检索）（回忆1和回忆2）。回忆1单独或协同进行，而回忆2单独进行。获得了协同抑制的代价，以及三种不同益处：错误修剪、错误记忆减少和协同后回忆益处。此外，本研究的新意义在于揭示了DRM词表中协同抑制和错误修剪对测试条件的敏感性，并表明协同对错误记忆的调节在协同期间和之后以相同方式发生。根据检索策略破坏假说及其他观点对这些结果进行了讨论。
