Using the technique of free association in an experimental setting, this author and colleagues previously found differences in the quality of memory traces involved in the production of REM and sleep onset (SO) dreams. The present study aims to answer two questions raised by those results: (a) Must the associative session be temporally contiguous to the dream production to gain access to the sources of the dream? (b) Are the differences between SO and REM associations due only to differences in structure and content of the two types of dream reports? Free associations with the same dream collected immediately after an experimental awakening were compared with those recalled 2 months later. A first group of results supports the hypothesis that free associations are sensitive to the proximity to the amount of dream production. A second group shows that the differences between SO and REM dreams noted in the previous research are not attributable to differences in formal characteristics of the report.
在实验环境中运用自由联想技术，该作者及其同事先前发现，快速眼动（REM）睡眠和睡眠起始（SO）梦境产生过程中涉及的记忆痕迹质量存在差异。本研究旨在回答由这些结果引发的两个问题：（a）联想环节是否必须在时间上与梦境产生紧密相连，才能触及梦境的源头？（b）SO和REM联想之间的差异是否仅归因于两种梦境报告在结构和内容上的差异？将实验性唤醒后立即收集的关于同一个梦境的自由联想与两个月后回忆起的自由联想进行了比较。第一组结果支持了这样的假设，即自由联想对与梦境产生量的接近程度敏感。第二组结果表明，先前研究中指出的SO和REM梦境之间的差异并非归因于报告形式特征的差异。
