According to some theories of recognition memory (e.g., S. Dennis & M. S. Humphreys, 2001), the number of different contexts in which words appear determines how memorable individual occurrences of words will be: A word that occurs in a small number of different contexts should be better recognized than a word that appears in a larger number of different contexts. To empirically test this prediction, a normative measure is developed, referred to here as context variability, that estimates the number of different contexts in which words appear in everyday life. These findings confirm the prediction that words low in context variability are better recognized (on average) than words that are high in context variability.
根据一些识别记忆理论(例如,S. 丹尼斯和M. S. 汉弗莱斯,2001),单词出现的不同语境数量决定了单词的各个出现情况的可记忆程度:出现在少量不同语境中的单词应该比出现在大量不同语境中的单词更容易被识别。为了实证检验这一预测,开发了一种规范测量方法,这里称为语境变异性,它估计了单词在日常生活中出现的不同语境数量。这些发现证实了这一预测,即语境变异性低的单词(平均而言)比语境变异性高的单词更容易被识别。
