增强对情绪刺激的记忆是一个有据可查的现象。在刺激编码过程中的情绪唤醒是这种记忆增强的一个中介。语义相关性等其他变量也在情绪刺激，尤其是言语刺激的记忆增强中发挥作用。研究还没有解决情绪唤起的贡献，由自我报告和自主测量索引，语义相关性对记忆表现。对20名年轻成人（10名女性）进行了中性无关词、学校相关词、中度唤起的情感词和高度唤起的禁忌词的测试，同时测量了他们的心率和皮肤电导。记忆测试采用自由回忆和识别测试。结果表明，具有语义相关性和高唤起性的禁忌语记忆效果最好。与学校相关的词汇，语义相关性高但唤醒性低，比中度唤起的情感词汇和语义不相关的中性词汇被记忆得更好。心理生理反应表明，在适度唤起的情绪词组和中性词组中，那些引起更大自主神经活动的词比那些没有引起这种活动的词更容易被记住。这些结果证明了语义关联和情绪唤醒对记忆的加性作用。亲缘性给记忆带来优势（如学校词汇），但亲缘性和唤醒性的结合（如禁忌词汇）会产生最好的记忆表现。(c) 2005 Elsevier B.V.版权所有
Increased memory for emotional stimuli is a well-documented phenomenon. Emotional arousal during the encoding of a stimulus is one mediator of this memory enhancement. Other variables such as semantic relatedness also play a role in the enhanced memory for emotional stimuli, especially for verbal stimuli. Research has not addressed the contributions of emotional arousal, indexed by self-report and autonomic measures, and semantic relatedness on memory performance. Twenty young adults (10 women) were presented neutral-unrelated words, school-related words, moderately arousing emotional words, and highly arousing taboo words while heart rate and skin conductance were measured. Memory was tested with free recall and recognition tests. Results showed that taboo words, which were both semantically related and high arousal were remembered best. School-related words, which were high on semantic relatedness but low on arousal, were remembered better than the moderately arousing emotional words and semantically unrelated neutral words. Psychophysiological responses showed that within the moderately arousing emotional and neutral word groups, those words eliciting greater autonomic activity were better remembered than words that did not elicit such activity. These results demonstrate additive effects of semantic relatedness and emotional arousal on memory. Relatedness confers an advantage to memory (as in the school-words), but the combination of relatedness and arousal (as in the taboo words) results in the best memory performance.
