Human memories are malleable and often shaped by social interactions. Previous work has demonstrated that not only one's own goals, but also those of a task-partner can facilitate subsequent retrieval of goal-relevant lexical stimuli, known as the Joint Memory Effect (JME). We outline a social-epistemic account of the JME which proposes that this memory enhancement reflects humans' tendency to map out their interaction partners' knowledge states, leading them to cognitively prioritize information relevant to and selectively attended by their partner. This account predicts that the memory enhancement for partner-relevant words should be limited to contexts where task partners are required to process their targets in terms of meaning, instead of attending to a surface feature. Additionally, we predicted that facilitated recall performance for partner-relevant information would be accompanied by enhanced memory for the social context of that information, that is, participants should be able to link the remembered content to the agent acting on it. The results of four experiments support these predictions. We demonstrate that the JME emerges selectively, depending on which stimulus feature (word meaning or presentation color) is attended by the partner, and that it extends to (and may even depend on) memory for the social context of the targets. Prioritizing partner-relevant information in memory may be linked to processes involved in establishing and monitoring common ground.

合作伙伴的任务对内容和来源记忆的影响。

人类的记忆是可塑的，通常由社会互动塑造。以前的工作表明，不仅自己的目标，而且任务伙伴的目标也可以促进随后检索与目标相关的词汇刺激，称为联合记忆效应 (JME)。我们概述了 JME 的社会认知解释，它提出这种记忆增强反映了人类绘制其互动伙伴的知识状态的倾向，导致他们在认知上优先考虑与其伙伴相关并由其选择性参与的信息。该帐户预测，与合作伙伴相关的单词的记忆增强应仅限于任务合作伙伴需要根据含义处理其目标的上下文，而不是关注表面特征。此外，我们预测，对于合作伙伴相关信息的促进回忆表现将伴随着对该信息的社会背景的增强记忆，也就是说，参与者应该能够将记住的内容与对其采取行动的代理联系起来。四项实验的结果支持这些预测。我们证明 JME 有选择地出现，这取决于合作伙伴参与的刺激特征（词义或呈现颜色），并且它扩展到（甚至可能取决于）目标社会背景的记忆。优先考虑记忆中的合作伙伴相关信息可能与建立和监控共同点所涉及的过程有关。参与者应该能够将记住的内容链接到对其采取行动的代理。四项实验的结果支持这些预测。我们证明 JME 有选择地出现，这取决于合作伙伴参与的刺激特征（词义或呈现颜色），并且它扩展到（甚至可能取决于）目标社会背景的记忆。优先考虑记忆中的合作伙伴相关信息可能与建立和监控共同点所涉及的过程有关。参与者应该能够将记住的内容链接到对其采取行动的代理。四项实验的结果支持这些预测。我们证明 JME 有选择地出现，这取决于合作伙伴参与的刺激特征（词义或呈现颜色），并且它扩展到（甚至可能取决于）目标社会背景的记忆。优先考虑记忆中的合作伙伴相关信息可能与建立和监控共同点所涉及的过程有关。并且它扩展到（甚至可能依赖于）目标社会背景的记忆。优先考虑记忆中的合作伙伴相关信息可能与建立和监控共同点所涉及的过程有关。并且它扩展到（甚至可能依赖于）目标社会背景的记忆。优先考虑记忆中的合作伙伴相关信息可能与建立和监控共同点所涉及的过程有关。
