本研究采用三个实验，考察了5个词汇变量（实例优势、类别优势、词频、字母词长和音节词长）对类别验证、词汇判断和发音3项词汇识别任务成绩的影响。虽然在每个任务中使用相同的一组单词，词汇变量与RT的关系随单词嵌入的任务而显着变化。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。概述了一个简单的两阶段模型来解释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其他研究的词汇决定和发音的一些发现。(49参考）（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
Three experiments with 80 undergraduates investigated the impact of 5 lexical variables (instance dominance, category dominance, word frequency, word length in letters, and word length in syllables) on performance in 3 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 RT varied significantly with the task within which the words were embedded. 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 2-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 findings in other studies of lexical decision and pronunciation.(49 ref)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
