Recent studies have shown higher resting-state vagally-mediated heart rate variability (vmHRV) to be related to greater memory retrieval. Research has not yet linked resting vmHRV with memory encoding and retrieval, as both are thought to play an important role in correctly distinguishing between true and false memories. The current study investigated this possible link in n = 71 undergraduate students. VmHRV was assessed during a 5-minute resting baseline period. Participants then completed the Deese-Roediger-McDermott (DRM) task, where they first viewed 6 word lists (12 words per list), and were later asked to identify previously shown words (true memories) and reject non-presented words. Results showed that participants with lower resting vmHRV were less able to discriminate true from false items. These data extend previous work on resting vmHRV and memory suggesting that resting vmHRV represents a psychophysiological pathway involved in both the proper encoding and retrieval of memories.
最近的研究表明，静息状态下迷走神经介导的心率变异性（vmHRV）较高与更好的记忆检索有关。研究尚未将静息 vmHRV 与记忆编码和检索联系起来，因为人们认为这两者在正确区分真实记忆和虚假记忆方面都起着重要作用。本研究在 n = 71 名大学生中调查了这种可能的联系。在 5 分钟的静息基线期评估 vmHRV。然后，参与者完成了 Deese-Roediger-McDermott（DRM）任务，他们首先观看了 6 个单词列表（每个列表 12 个单词），然后被要求识别之前显示的单词（真实记忆）和拒绝未显示的单词。结果表明，静息 vmHRV 较低的参与者较难区分真实和虚假项目。这些数据扩展了关于静息 vmHRV 和记忆的先前研究，表明静息 vmHRV 代表了参与记忆适当编码和检索的心理生理途径。
