Social influences on action and memory are well established. However, it is unknown how acting together affects the incidental encoding of information. The present study asked whether coactors encode information that is relevant to a partner's task, but irrelevant to their own task. In Experiment 1, participants performed a categorization task alone and together, followed by a surprise free recall test where they were asked to recall items from the categorization task. Recall was better not only for items that participants had responded to themselves, but also for items that their coactor had responded to, than for items that had not required a response. The same results were found in Experiment 2, even though financial incentives motivated participants to only encode words they had responded to themselves. Together, the findings suggest that performing tasks together can modulate how information relevant to coactors is processed. Shared task representations may act as a vehicle for establishing shared memories.
社会对行动和记忆的影响已得到充分证实。然而，共同行动如何影响信息的偶然编码尚不清楚。本研究探讨了共同行动者是否会编码与伙伴任务相关但与自身任务无关的信息。在实验1中，参与者单独和一起执行分类任务，随后进行意外自由回忆测试，要求他们回忆分类任务中的项目。结果发现，参与者不仅对自己做出反应的项目回忆得更好，而且对其共同行动者做出反应的项目的回忆也比对不需要做出反应的项目更好。在实验2中也发现了相同的结果，尽管经济激励促使参与者只编码他们自己做出反应的单词。总之，研究结果表明，共同执行任务可以调节与共同行动者相关的信息的处理方式。共享的任务表征可能是建立共享记忆的一种媒介。
