摘　　要：本研究以自编情绪DRM词表为实验材料,用音乐诱发正常大学生被试正性、负性和中性心境,探讨在被试处于某种心境下时是否产生心境一致性错误记忆现象、预警能否减少心境一致性错误记忆的发生。结果表明,正性关键诱饵在正性心境下的错误再认率显著高于中性和负性心境,负性关键诱饵在负性心境下的错误再认率显著高于中性和正性心境,说明正常被试也会产生心境一致性错误记忆;预警和无预警条件下被试对关键诱饵和心境一致性关键诱饵的错误再认率无显著差异,说明外显的预警提示并不能消除部分由无意识产生的错误记忆和心境一致性错误记忆。研究结果支持记忆的扩散激活理论和情感的联想网络理论。The memory of people are not always correct, when people sometimes declare to remember some events that in fact has never occurred, this is how false memories produced. Spreading activation theory tries to explain the mechanism of false memories. According to this theory, semantics related information is organized together in memory. Semantic activation of the learning items will spread to critical lures that have semantic association with the items through semantic network and thus activates the critical lures to generate false memory. Due to the fact that false memory has important influence on daily life, many researches focus on how to reduce false memory. Presenting a warning signal is the most common method in the laboratory to reduce false memory. DRM paradigm only shows one type of human false memory phenomenon. Studies show that mood also has great influence on human memory and this effect is mainly reflected in mood-congruent memory bias. Bower （1981） used associative network theory of emotion to explain this phenomenon. Based on spreading activation theory and associative network theory of emotion, we hypothesized that unconsciously spreading activated semantic and emotional information leads people to retrieve mood-congruent information. This information includes original input information and moods and semantics related non-original information, namely false memory information. False retrieval of mood-congruent non-original information generates mood-congruent false memory. Therefore, Experiment 1 examined whether the existence of mood-congruent false memory among normal participants. After warning cues were added, experiment 2 explored whether warning cue can reduce false memory. This study will explore the hypothesis： （1） error recognition rate of positive critical lures in the positive mood is significantly higher than that in the negative and neutral moods, and error recognition rate of negative critical lures in the negative mood is significantly higher than that in the positive and ne
