阅读过程中单词识别和动眼神经过程的协调通过眼动追踪实验进行了评估，该实验检查了跳字（在第一次阅读过程中没有固定单词）如何受到旁凹中字母串的词汇状态以及识别该字符串的难易程度的影响。词汇识别的难易程度是通过目标词频率（实验 1）和嵌入句子中的主要目标对之间的重复启动（实验 2）来控制的。使用凝视相关边界技术，目标词以完整预览或转置字母 (TL) 预览的方式出现在中央凹中。实验 1 中的 TL 预览字符串是非单词（例如，从目标眨眼创建的 bilnk），但在实验 2 中是单词（例如，从目标害怕创建的神圣）。实验 1 显示，在完整预览条件下，高频目标词的跳跃量大于低频目标词的跳跃量，但在 TL 预览（非词）条件下则不然。实验 2 显示，重复较早启动词的目标词比不重复的目标词有更多的跳跃，这种重复启动既发生在预览完整目标的情况下，也发生在预览目标 TL 相邻单词的情况下。然而，跳过 TL 预览单词（其含义在句子上下文中异常）之后，从目标后面的单词开始的时间比跳过完整预览单词（其含义明显符合句子上下文）的时间要长。总之，这些结果支持了这样的观点：单词识别和动眼神经过程之间的协调发生在隐含词汇决策的层面上。
The coordination of word-recognition and oculomotor processes during reading was evaluated in eye-tracking experiments that examined how word skipping, where a word is not fixated during first-pass reading, is affected by the lexical status of a letter string in the parafovea and ease of recognizing that string. Ease of lexical recognition was manipulated through target-word frequency (Experiment 1) and through repetition priming between prime-target pairs embedded in a sentence (Experiment 2). Using the gaze-contingent boundary technique the target word appeared in the parafovea either with full preview or with transposed-letter (TL) preview. The TL preview strings were nonwords in Experiment 1 (e.g., bilnk created from the target blink), but were words in Experiment 2 (e.g., sacred created from the target scared). Experiment 1 showed greater skipping for high-frequency than low-frequency target words in the full preview condition, but not in the TL preview (nonword) condition. Experiment 2 showed greater skipping for target words that repeated an earlier prime word than for those that did not, with this repetition priming occurring both with preview of the full target and with preview of the target's TL neighbor word. However, time to progress from the word after the target was greater following skips of the TL preview word, whose meaning was anomalous in the sentence context, than following skips of the full preview word whose meaning fit sensibly into the sentence context. Together, the results support the idea that coordination between word-recognition and oculomotor processes occurs at the level of implicit lexical decisions.
