Psychological and pharmacological studies in humans suggest that emotional arousal enhances long-term memory. In this paper we used, in an Italian sample, an adaptation of a paradigm previously utilized in American samples to study the relationship between emotion and long-term memory. Seventy-two healthy adults from different educational backgrounds were randomly assigned either to a neutral group or to an emotional arousal group and then told a short story, presented audio-visually. In both groups, the slides shown and the slide sequence were the same, and the images were accompanied by a narrative. The two versions of the story differed primarily in their emotional content. Shortly after viewing the slide presentation, the participants were asked to rate the emotionality of the narrative, and ten days later were submitted to a retention test. The emotionally-arousing version of the story was rated as more emotional than the neutral one. Compared with the members of the neutral group, the subjects in the arousal group recalled a significantly higher number of elements from the story. There was no overall difference between the two groups in performance on the recognition memory test. These results confirm that the emotional content of stimuli enhances long-term declarative memory of those stimuli, and indicate the possible usefulness of applying the paradigm utilized in this study to different clinical samples from various cultural backgrounds.
针对人类的心理学和药理学研究表明，情绪唤起能增强长期记忆。在本文中，我们在一个意大利样本中采用了一种先前在美国样本中使用过的范式改编版，以研究情绪与长期记忆之间的关系。来自不同教育背景的72名健康成年人被随机分配到中性组或情绪唤起组，然后通过视听方式向他们讲述一个短篇故事。在两组中，展示的幻灯片及其顺序相同，且图像都配有旁白。故事的两个版本主要在情感内容上有所不同。观看幻灯片展示后不久，要求参与者对旁白的情感程度进行评分，十天后进行记忆保持测试。情绪唤起版的故事被评为比中性版更具情感性。与中性组的成员相比，唤起组的受试者从故事中回忆起的元素数量显著更多。在识别记忆测试中，两组的表现没有总体差异。这些结果证实，刺激的情感内容会增强对这些刺激的长期陈述性记忆，并表明将本研究中使用的范式应用于来自不同文化背景的不同临床样本可能是有用的。
