Several studies have documented that emotional arousal may enhance long-term memory. This is an adaptation of a paradigm previously used in North American and European samples in investigations of the influence of emotion on long-term retention. A sample of 46 healthy adults of high and low educational levels watched a slide presentation of stories. A randomly assigned group watched a story with an arousing content and another group watched a neutral story. The stories were matched for structure and comprehensibility and the set and order of the 11 slides were the same in both conditions. Immediately after viewing the slide presentation, the participants were asked to rate the emotionality of the narrative. The arousing narrative was rated as being more emotional than the neutral narrative (t(44) = -3.6, P<0.001). Ten days later subjects were asked to remember the story and answer a multiple-choice questionnaire about it. The subjects who watched the arousing story had higher scores in the free recall measure (t(44) = -2.59, P<0. 01). There were no differences between groups in the multiple-choice test of recognition memory (t(44) = 0.26). These findings confirm that an emotional arousing content enhances long-term declarative memory and indicate the possibility of applying this instrument to clinical samples of various cultural backgrounds.
多项研究表明，情绪唤起可能会增强长期记忆。这是对先前在北美和欧洲样本中用于研究情绪对长期记忆影响的一种范式的改编。46名受教育程度高低不同的健康成年人观看了一组故事幻灯片。随机分配的一组观看了一个具有刺激性内容的故事，另一组观看了一个中性故事。这些故事在结构和可理解性方面进行了匹配，两种情况下11张幻灯片的设置和顺序相同。观看幻灯片后，参与者立即被要求对叙述的情感程度进行评分。刺激性叙述的情感评分高于中性叙述（t(44) = -3.6，P<0.001）。十天后，要求受试者回忆故事并回答关于该故事的多项选择题问卷。观看刺激性故事的受试者在自由回忆测试中的得分更高（t(44) = -2.59，P<0.01）。在识别记忆的多项选择题测试中，两组之间没有差异（t(44) = 0.26）。这些发现证实，刺激性情绪内容会增强长期陈述性记忆，并表明将该方法应用于不同文化背景临床样本的可能性。
