情绪唤起和长期记忆之间的关系是在两个实验中解决的，在这些实验中，受试者观看了一个相对情绪中立的短篇故事（以简短的幻灯片展示）或一个密切匹配但更情绪唤起的故事，并在2周后测试了故事的保留。实验1提供了Heuer和Reisberg（1990）结果的基本复制，并说明了在中性故事与情感故事中使用不同刺激（幻灯片）所造成的常见解释问题。在实验2中，相同的幻灯片（和序列）中使用的中性和唤醒的故事。两个不同的故事是通过改变每一张幻灯片的叙述来创造的。在这两个实验中，观看唤起故事的受试者都比观看中性故事的受试者经历了更大的情感反应，随后表现出对故事的记忆增强。在实验2中，观看唤起故事的受试者也比观看中性故事的受试者回忆起更多的幻灯片。这种影响在故事阶段2中最大，这一阶段发生了情绪化的幻灯片叙述。由于这种增强的故事幻灯片的保留不能用幻灯片本身的任何差异来解释，因此这些结果提供了新的证据来支持情绪唤醒影响正常人类受试者长期记忆的论点。(C)出版社：Academic Press
The relationship between emotional arousal and long-term memory is addressed in two experiments in which subjects viewed either a relatively emotionally neutral short story (presented as a brief slide show) or a closely matched but more emotionally arousing story and were tested for retention of the story 2 weeks later. Experiment 1 provides an essential replication of the results of Heuer and Reisberg (1990) and illustrates the common interpretive problem posed by the use of different stimuli (slides) in the neutral versus emotional stories. In Experiment 2, identical slides (and sequence) were used in both the neutral and arousal stories. Two different stories were created by varying the narration that accompanied each slide. Ln both experiments, subjects who viewed the arousal story both experienced a greater emotional reaction to the story than did the subjects who viewed the neutral story, and subsequently exhibited enhanced memory for the story. Subjects in Experiment 2 who viewed the arousal story also recalled more slides than did the subjects who viewed the neutral story. This effect was greatest for story phase 2, the phase in which the emotional slide narration occurred. Because this enhanced retention of the story slides cannot be explained by any differences in the slides themselves, the results provide new evidence to support the contention that emotional arousal influences long-term memory in normal human subjects.
