Memory retrieval is a cognitive operation that itself can be remembered or forgotten, with potentially important consequences. To study memory for prior remembering, we had participants first study target words (e.g., bark) alongside semantically related cue words (e.g., dog). Then, on Test 1, participants retrieved targets in response to either the study cue or a changed cue that was semantically related to a homograph of the target (e.g., birch). Finally, on Test 2, participants retrieved all targets in response to the original study cues, and participants judged whether targets were previously retrieved on Test 1. As in previous research, cue change on Test 1 rendered target retrievals less memorable, suggesting context changes harm memory for prior remembering. We hypothesised that the negative effect of context change could be ameliorated by reminding participants of the original study cues during Test 1. We had participants either retrieve (Experiments 1 and 3, Ns = 46 and 62) or view (Experiment 2, N = 118) the study cue following each target retrieval. Reminding significantly reduced the negative effect of cue change, with self-generation being especially potent. This indicates that reminding can make remembering more memorable in the face of context change.
记忆提取是一种认知操作,其本身可能被记住或遗忘,这可能会产生潜在的重要后果。为了研究对先前记忆的记忆,我们让参与者首先将目标词(如bark)与语义相关的线索词(如dog)一起学习。然后,在测试1中,参与者根据学习线索或与目标词同形异义词语义相关的变化线索(如birch)来提取目标词。最后,在测试2中,参与者根据原始学习线索提取所有目标词,并判断目标词在测试1中是否曾被提取过。与之前的研究一样,测试1中的线索变化使目标词的提取记忆效果变差,这表明情境变化会损害对先前记忆的记忆。我们假设,在测试1期间提醒参与者原始学习线索可以减轻情境变化的负面影响。我们让参与者在每次目标词提取后要么提取(实验1和3,样本量分别为46和62)要么查看(实验2,样本量为118)学习线索。提醒显著降低了线索变化的负面影响,自我生成尤其有效。这表明在面对情境变化时,提醒可以使记忆更易于被记住。
