从3个单词识别实验中获得的反应时（RT）分布进行了分析，通过拟合前高斯函数的经验数据，以确定词频，重复和词汇的基本分布的性质的主要影响和交互影响。前高斯分析允许确定操作是否简单地移动响应时间（RT）分布，产生RT分布的偏斜，或两者兼而有之。与命名表现相反，词汇决策结果表明，词频，重复和词汇性的主要影响和相互作用主要反映了RT分布的倾斜增加，而不是简单的RT分布的变化。实验结果的意义被解释为一个混合的词汇判断两阶段模型。
Response time (RT) distributions obtained from 3 word recognition experiments were analyzed by fitting an ex-Gaussian function to the empirical data to determine the main effects and interactive influences of word frequency, repetition, and lexicality on the nature of the underlying distributions. The ex-Gaussian analysis allows one to determine if a manipulation simply shifts the response time (RT) distribution, produces a skewing of the RT distribution, or both. In contrast to naming performance, the lexical decision results indicated that the main effects and interactions of word frequency, repetition, and lexicality primarily reflect increased skewing of the RT distributions, as opposed to simple shifts of the RT distributions. The implications of the results were interpreted within a hybrid 2-stage model of lexical decision performance.
