两个实验检验了以下假设：阅读中的词汇访问是根据在parafoveal区域获得的单词初始字母信息开始的。当大学生阅读句子时，对眼睛的运动进行了监测，这些句子包含目标词，其初始Trigram（实验1）或Bigram（实验2）在词典中施加了高度或较低程度的约束。与我们的假设相矛盾，尽管高构造单词具有高分辨率单词，但高构造单词（例如，矮人）的固定性比低规定的单词（例如小丑）更长词典。此外，对带有和不带有parafoveal字母信息的观察条件中的固定时间进行比较表明，由于先前的parafoveal可用性，目标固定时间的减少量对于高构造和低构造目标是相同的。我们得出的结论是，对单词初始字母序列的熟悉程度增加对词汇访问有益，并且这种熟悉程度会影响中央凹的效率，但不影响偏羊形处理。
Two experiments tested the hypothesis that lexical access in reading is initiated on the basis of word-initial letter information obtainable in the parafoveal region. Eye movements were monitored while college students read sentences containing target words whose initial trigram (Experiment 1) or bigram (Experiment 2) imposed either a high or a low degree of constraint in the lexicon. In contradiction to our hypothesis, high-constraint words (e.g., DWARF) received longer fixations than did low-constraint words (e.g., CLOWN), despite the fact that high-constraint words have an initial letter sequence shared by few other words in the lexicon. Moreover, a comparison of fixation times in viewing conditions with and without parafoveal letter information showed that the amount of decrease in target fixation time due to prior parafoveal availability was the same for high-constraint and low-constraint targets. We concluded that increased familiarity of word-initial letter sequence is beneficial to lexical access and that familiarity affects the efficiency of foveal but not parafoveal processing.
