Numerous studies have shown that speakers will affect listeners’ memories in a conversation. Especially when listeners concurrently retrieve the information with the speaker, listeners’ memories will be reshaped through the way of socially shared retrieval-induced forgetting (SS-RIF). Using a modified retrieval-induced forgetting paradigm, we explored the effects of speakers’ expertise and listeners’ attitude toward euthanasia on SS-RIF when the conversation topic was general (Experiment 1) and self-relevant (Experiment 2). Our results showed that SS-RIF was more likely to emerge when speakers were perceived as non-experts than when speakers were perceived as experts. Additionally, when the topic was self-relevant, SS-RIF also could appear when the attitude of the listener was consistent with that of the expert speaker. These findings suggest that listeners’ memories can be influenced by the social relationship and the consistency of attitude between speakers and listeners in important medical decision-making tasks.

大量研究表明，说话者在谈话中会影响听者的记忆。特别是当听者与说话者同时检索信息时，听者的记忆将通过社会共享检索诱发遗忘（SS-RIF）的方式重塑。使用修改后的检索诱发遗忘范式，我们探讨了当对话主题是一般性的（实验 1）和自我相关的（实验 2）时，说话者的专业知识和听众对安乐死的态度对 SS-RIF 的影响。我们的结果表明，当演讲者被视为非专家时，SS-RIF 更有可能出现，而不是当演讲者被视为专家时。此外，当话题是自相关的时，当听者的态度与专家说话者的态度一致时，SS-RIF 也会出现。
