This study investigates the time course of incorporation of waking life experiences into daydreams. Thirty-one participants kept a diary for 10 days, reporting major daily activities (MDAs), personally significant events (PSEs) and major concerns (MCs). They were then cued for daydream, Rapid Eye Movement (REM) and N2 dream reports in the sleep laboratory. There was a higher incorporation into daydreams of MCs from the previous two days (day-residue effect), but no day-residue effect for MDAs or PSEs, supporting a function for daydreams of processing current concerns. A day-residue effect for PSEs and the delayed incorporation of PSEs from 5 to 7 days before the dream (the dream-lag effect) have previously been found for REM dreams. Delayed incorporation was not found in this study for daydreams. Daydreams might thus differ in function from REM sleep dreams. However, the REM dream-lag effect was not replicated here, possibly due to design differences from previous studies.
本研究调查了清醒生活经历融入白日梦的时间进程。31名参与者记录了10天的日记，报告主要日常活动（MDA）、个人重大事件（PSE）和主要担忧（MC）。随后，他们在睡眠实验室中被提示进行白日梦、快速眼动（REM）和N2梦境报告。前两日的主要担忧（MC）更多地融入到白日梦中（日间残留效应），但主要日常活动（MDA）或个人重大事件（PSE）不存在日间残留效应，这支持了白日梦对处理当前担忧具有作用的观点。先前在REM梦境中发现了个人重大事件（PSE）的日间残留效应以及梦境前5至7天个人重大事件（PSE）的延迟融入（梦境延迟效应）。本研究中未发现白日梦存在延迟融入现象。因此，白日梦的功能可能与REM睡眠梦境不同。然而，此处未重复出现REM梦境延迟效应，这可能是由于与先前研究的设计差异所致。
