三个实验研究了五个词汇变量（实例优势，类别优势，词频，字母中的单词长度和音节中的单词长度）在三个不同的任务中对表现的影响，涉及单词识别：类别验证，词汇决策和发音。虽然在每个任务中使用相同的一组单词，词汇变量的反应时间的关系变化显着的任务内的话嵌入。特别是，词频的影响是最小的类别验证任务，而它是显着较大的发音任务和显着较大的词汇决策任务。有人认为，决策过程没有什么关系的词汇访问突出的词频效应在词汇决策任务，从这个任务的结果有值得怀疑的价值，在测试的假设，词频命令的词汇，从而影响时间访问的心理词汇。一个简单的两阶段模型概述了词频和其他变量在词汇决策中的作用。该模型适用于报告的实验结果和一些最重要的发现在其他研究的词汇决策和发音。
Three experiments investigated the impact of five lexical variables (instance dominance, category dominance, word frequency, word length in letters, and word length in syllables) on performance in three different tasks involving word recognition: category verification, lexical decision, and pronunciation. Although the same set of words was used in each task, the relationship of the lexical variables to reaction time varied significantly with the task within which the words were embedded. In particular, the effect of word frequency was minimal in the category verification task, whereas it was significantly larger in the pronunciation task and significantly larger yet in the lexical decision task. It is argued that decision processes having little to do with lexical access accentuate the word-frequency effect in the lexical decision task and that results from this task have questionable value in testing the assumption that word frequency orders the lexicon, thereby affecting time to access the mental lexicon. A simple two-stage model is outlined to account for the role of word frequency and other variables in lexical decision. The model is applied to the results of the reported experiments and some of the most important findings in other studies of lexical decision and pronunciation.
