读者阅读的句子中包含的目标词的频率和可预测性各不相同。所观察到的模式的固定持续时间的数据只有轻微偏离加性，预测效果是略大于低频比高频字。跳跃的数据模式是不同的，因为可预测性只影响高频目标词的跳跃概率。使用E-Z Reader模型对这些数据进行模拟表明，单过程模型不太可能为这两种措施提供良好的拟合。该模型的一个版本，假设（a）词编码时间是受频率和可预测性和（B）与目标词的词汇后处理的困难，导致双重考虑占的数据，同时表明假设的词编码阶段的持续时间和观察到的固定持续时间之间的关系是不可能是透明的。
Readers read sentences containing target words varying in frequency and predictability. The observed pattern of data for fixation durations only mildly departed from additivity, with predictability effects that were slightly larger for low-frequency than for high-frequency words. The pattern of data for skipping was different as predictability affected only the probability of skipping for high-frequency target words. Simulations of these data using the E-Z Reader model indicated that a single-process model was unlikely to provide a good fit for both measures. A version of the model that assumes that (a) word-encoding time is additively affected by frequency and predictability and (b) difficulty with postlexical processing of the target word causes a double take accounted for the data while indicating that the relationship between the duration of hypothesized word-encoding stages and observed fixation durations is not likely to be transparent.
