Listening to a speaker selectively practicing previously encoded information leads to better memory for the practiced information, but at the same time results in induced forgetting of related memories. These effects have been found to occur due to the concurrent, and covert, retrieval of information on the part of the listener. Using a modified version of the method of serial reproduction (Bartlett, 1932), this study explored the degree to which rehearsal and retrieval-induced forgetting effects propagated in 64 3-person-chains of connected participants. We manipulated the degree of concurrent retrieval from the part of the listener by activating high and low relational motivations during the listening task. We showed that the degree of propagation of retrieval-induced forgetting was larger when concurrent retrieval was activated (high-relational motivation) than when concurrent retrieval was attenuated (low-relational motivation). This study provides a framework that aims to bridge between micro-level cognitive phenomena and macro-level social dynamics.

忘记社会链：认知对信息传播的影响

听说话者有选择地练习先前编码的信息会导致对练习后的信息有更好的记忆，但是同时导致相关记忆的遗忘。已经发现这些效果是由于侦听器同时进行和隐蔽地检索信息而发生的。使用串行复制方法的改进版本（Bartlett，1932年），该研究探索了彩排和检索引起的遗忘效应在连接参与者的64条3人链中传播的程度。我们通过在听力任务中激活高低的关系动机来控制从听众那里进行并发检索的程度。我们发现，激活并发检索（高关系动机）时，由检索引起的遗忘的传播程度要大于减弱并发检索（低关系动机）时的传播程度。本研究提供了一个旨在在微观认知现象和宏观社会动态之间架起桥梁的框架。
