Social interactions create opportunities for reminiscence and memory rehearsal but can also lead to memory errors. We tested how the type of information people remember can influence the magnitude of memory errors they make following collaborative discussion. Past findings show that unrelated item lists and emotional salient items reduce false alarms and improve memory discrimination, respectively, on an individual recognition test after collaborative discussion compared to no prior collaboration. In contrast, for associatively related materials with high relatedness (e.g., bed, rest, awake, tired, dream, etc.) collaboration increases false recognition memory for the critical lures (e.g., sleep) on a later individual test. We tested whether the error-pruning benefits of collaboration are restricted to unrelated and emotional information or can also occur for other classes of related information that produce high memory errors. Using categorized stimuli, we created conditions that produced high or low memory errors for the same targets (12 versus 2 target exemplars per category across study lists of equal length). Replicating past research, collaboration increased the accuracy of recognition memory and large category size decreased it. The critical novel finding showed that collaboration pruned individual recognition errors by reducing false alarms not only in the low memory error condition but also the high memory error condition. This study delineates the conditions where collaboration can prune memory errors for related information.

当社会影响减少错误识别记忆时:分类相关信息的案例。

社交互动为回忆和记忆排练创造了机会,但也可能导致记忆错误。我们测试了人们记忆的信息类型如何影响他们在协作讨论后所犯的记忆错误的程度。过去的研究结果表明,在协作讨论后的个人识别测试中,与之前没有协作相比,不相关的项目列表和情感显着项目分别减少了误报并改善了记忆辨别力。相反,对于具有高度相关性的关联相关材料(例如,床、休息、清醒、疲倦、做梦等),协作增加了对关键诱饵(例如,睡眠)的错误识别记忆) 在以后的个人测试中。我们测试了协作的错误修剪好处是否仅限于无关和情感信息,或者也可能发生在其他类别的相关信息中,这些信息会产生高记忆错误。使用分类刺激,我们创造了对相同目标产生高或低记忆错误的条件(在相同长度的研究列表中,每个类别有 12 个对 2 个目标样本)。复制过去的研究,合作提高了识别记忆的准确性,而大类别规模降低了它。关键的新发现表明,协作通过减少错误警报来减少个体识别错误,不仅在低内存错误条件下,而且在高内存错误条件下。这项研究描述了协作可以消除相关信息的记忆错误的条件。
