The Remember-Know (R-K) task is commonly used to differentiate between recollection and familiarity-based recognition memory. To further validate this test, we assessed the number of contextual details available to participants after giving R or K responses. We also examined the effect of retention interval on the episodic character of memories by administering the R-K task after both 10-minute and 1-week retention intervals. At 1 week, items receiving R responses were accompanied by a significant number of episodic details, while K responses were not. A large number of items that received R responses at the 10-minute delay received K responses at 1 week, and these items were not accompanied by episodic detail during the later test. Items that were judged familiar at 10-minutes but were labeled as recollected at 1 week were also not accompanied by significant memory of the study episode, suggesting that these items were recollected from the first test session. Overall, the data are consistent with the idea that R responses, unlike K responses, are accompanied by memory for episodic detail, and that the loss of memory for episodic detail over time parallels the conversion of R responses to K responses.
记住-知道（R-K）任务通常用于区分回忆和基于熟悉度的识别记忆。为了进一步验证该测试，我们在参与者给出R或K反应后，评估了他们可获得的情境细节数量。我们还通过在10分钟和1周的保持间隔后进行R-K任务，研究了保持间隔对记忆情节特征的影响。在1周时，得到R反应的项目伴随着大量的情节细节，而K反应则没有。大量在10分钟延迟时得到R反应的项目在1周时得到了K反应，并且在后续测试中这些项目没有伴随着情节细节。在10分钟时被判断为熟悉但在1周时被标记为回忆起来的项目，在研究情节中也没有显著的记忆伴随，这表明这些项目是从第一次测试环节中回忆起来的。总体而言，数据与以下观点一致：与K反应不同，R反应伴随着对情节细节的记忆，并且随着时间的推移情节细节记忆的丧失与R反应向K反应的转变并行。
