对情感项目的记忆通常比对中性项目的记忆要好。在三个实验中，我们检查了这一典型发现是否是由于情感项目固有的较高语义相关性所致，这在之前的研究中是一个混淆。我们还控制了其他可能的混杂变量，例如图像。在实验 1 和 2 中，参与者对语义相关性相当的情感和分类中性词列表以及语义相关性较低的随机中性词列表进行编码。在实验 3 中，列表是混合的，包含所有条件下的单词。在 40 至 55 分钟的保留间隔后测试无意外回忆。情绪词的自由回忆比随机中性词的回忆要好，复制了经典效果。重要的是，分类单词比随机中性单词的记忆效果更好，并且不比情感单词差。这些结果强调了语义相关性在经典效应中的重要作用，并表明组织过程与唤醒相关过程一起运作，以增强对情感材料的记忆。
Memory for emotional items is often better than memory for neutral items. In three experiments, we examined whether this typical finding is due to the higher semantic relatedness inherent to emotional items, a confound in previous studies. We also controlled for other possible confounding variables, such as imagery. In Experiments 1 and 2, participants encoded lists of emotional and categorized neutral words equivalent in semantic relatedness, as well as lists of random neutral words with lower semantic relatedness. In Experiment 3, the lists were mixed, containing words from all the conditions. Surprise free recall was tested after a 40- to 55-min retention interval. Free recall of emotional words was better than that of random neutral words, replicating the classic effect. Importantly, categorized words were recalled better than random neutral words, and not worse than emotional words. These results emphasize the important role of semantic relatedness in the classic effect and suggest that organizational processes operate alongside arousal-related ones to enhance memory for emotional material.
