A primary interest in the psychological study of collective memory concerns the sociocognitive processes by which Central Speakers-politicians, journalists, and other public voices-may reshape the memory of groups of listeners. In 2 experiments, we examine how (a) Central Speakers may induce shared practice effects and socially shared retrieval-induced forgetting (SSRIF) for related but unmentioned items in a group of listeners, (b) how communicational remembering along a serial transmission chain can moderate this initial mnemonic influence, and (c) how listeners' relational motives toward the Central Speaker, operationalized as perceived social group membership, impact both (a) and (b). Experiment 1 shows that a Central Speaker may induce both SSRIF and shared practice effects in a group of listeners, and that, relative to noncommunicating nominal groups, communicational remembering in a looped serial transmission chain amplifies the relative inaccessibility of related but unmentioned items. In Experiment 2, we show that the Central Speaker's perceived group membership moderates the effects of subsequent communicational remembering. When ingroup, communicational remembering amplifies the Central Speaker's SSRIF, when outgroup, subsequent communicational remembering attenuates it.

对集体记忆的心理学研究的一个主要兴趣在于中央说话者（政治家、记者和其他公众声音）重塑听众群体记忆的社会认知过程。在 2 项实验中，我们研究了（a）中央说话者如何在一群听众中引起共享的练习效应和社会共享的检索诱导遗忘（SSRIF），以及相关但未提及的项目，（b）沿着串联传输链进行的交流记忆如何调节这种初始记忆影响，以及（c）听众对中央说话者的关系动机（表现为感知的社会群体成员身份）如何影响（a）和（b）。实验 1 表明，中央说话者可以在一群听众中引起 SSRIF 和共享的练习效应，并且与非交流的名义群体相比，在循环串联传输链中的交流记忆会放大相关但未提及项目的相对不可及性。在实验 2 中，我们表明中央说话者的感知群体成员身份调节了随后交流记忆的效果。当属于内群体时，交流记忆会放大中央说话者的 SSRIF，而当属于外群体时，随后的交流记忆会减弱它。（PsycINFO 数据库记录（c）2020 APA，保留所有权利）。
