两个实验评估了词汇难度对文本理解记忆、摘要记忆和句子识别三个测试的影响。在实验1中，我们考察了不同比例的稀有词替换的影响。研究发现，在对理解产生明显的可靠效果之前，需要较高的难度词汇率（三个实体词中有一个实体词）。在实验2中，在一种形式的文章中，难词汇被放在重要的文本元素中，而在另一种形式的文章中，难词汇被放在不重要的元素中。比较了这些形式与简单词汇形式对三项理解的影响。只有在综合测试中，困难词汇在重要要素上有整体影响。研究结果从不熟悉词的信号价值的显著性角度进行了讨论。
Two experiments assessed the effect of vocabulary difficulty on three measures of text comprehension—free recall, summary recall, and sentence recognition. In Experiment 1, the effects of differing proportions of rare-word substitutions were examined. It was found that a high rate of difficult vocabulary (one substance word in three) was required before reliable effects on comprehension were evident. In Experiment 2, difficult vocabulary was placed in important text elements in one form of the passages, and in unimportant elements in another. These forms were contrasted with easy vocabulary forms in their effects on the three comprehension measures. Only on the summary measure was there an overall effect of difficult vocabulary in important elements. The results are discussed in terms of the salience of the signaling value of unfamiliar words.
