Many situations require us to generate external cues to support later retrieval from memory. For instance, we create file names in order to cue our memory to a file's contents, and instructors create lecture slides to remember what points to make during classes. We even generate cues for others when we remind friends of shared experiences or send colleagues a computer file that is named in such a way so as to remind them of its contents. Here we explore how and how well learners tailor retrieval cues for different intended recipients. Across three experiments, subjects generated verbal cues for a list of target words for themselves or for others. Learners generated cues for others by increasing the normative cue-to-target associative strength but also by increasing the number of other words their cues point to, relative to cues that they generated for themselves. This strategy was effective: such cues supported higher levels of recall for others than cues generated for oneself. Generating cues for others also required more time than generating cues for oneself. Learners responded to the differential demands of cue generation for others by effortfully excluding personal, episodic knowledge and including knowledge that they estimate to be broadly shared.
许多情况都要求我们生成外部线索,以支持日后从记忆中检索信息。例如,我们创建文件名以便唤起对文件内容的记忆,教师制作讲课幻灯片以记住课堂上要讲的要点。当我们提醒朋友共同经历的事情,或者给同事发送一个文件名能让他们想起文件内容的计算机文件时,我们甚至会为他人生成线索。在这里,我们探讨学习者如何以及在多大程度上为不同的目标接收者定制检索线索。在三个实验中,受试者为自己或他人生成一系列目标单词的语言线索。学习者为他人生成线索时,不仅增加了规范的线索与目标的关联强度,而且相对于为自己生成的线索,还增加了线索指向的其他单词的数量。这种策略是有效的:与为自己生成的线索相比,这类线索能支持他人更高水平的回忆。为他人生成线索也比为自己生成线索需要更多时间。学习者通过努力排除个人的、情景性的知识,并纳入他们估计为广泛共享的知识,来应对为他人生成线索的不同要求。
