The study examined the effect of negative emotion on consolidation of both item and source memory. Participants learned words read by either a male or female. Then they watched either a negative or a neutral video clip. Memory tests were carried out either 25min or 24h after learning. The study yielded the following findings. First, negative emotion enhanced consolidation of item memory as measured by recognition memory in the 25-min delay, and enhanced consolidation of item memory as measured by free recall in both the 25-min and the 24-h delay. Second, negative emotion had little effect on consolidation of source memory, either in the 25-min or the 24-h delay. These findings provide evidence for the differential effects of negative emotion on item memory and source memory and have implications for using emotion as a strategy to intervene memory consolidation.
该研究考察了负面情绪对项目记忆和源记忆巩固的影响。参与者学习由男性或女性朗读的单词。然后他们观看一段负面或中性的视频片段。学习后25分钟或24小时进行记忆测试。该研究得出了以下结果。首先，负面情绪增强了项目记忆的巩固，在25分钟延迟时通过识别记忆来衡量，并且在25分钟和24小时延迟时通过自由回忆来衡量均增强了项目记忆的巩固。其次，负面情绪对源记忆的巩固几乎没有影响，无论是在25分钟还是24小时延迟时。这些发现为负面情绪对项目记忆和源记忆的不同影响提供了证据，并对将情绪作为一种干预记忆巩固的策略具有启示意义。
